The component equipment allocation apparatus 10 of this embodiment performs production management of products using a plurality of equipment. Hereinafter, the product manufactured by the equipment will be described as “parts”. Hereinafter, the equipment will be described as manufacturing parts, but the manufacturing includes parts production and processing.

  The component equipment allocation device 10 of the present embodiment is a PC (Personal Computer), a tablet terminal, or the like. The parts equipment allocation device 10 has manufacturing plan information in which parts to be manufactured are assigned to a plurality of equipments in advance. The parts equipment allocation device 10 performs processing for determining equipment for substituting production of products and parts to be substituted when the production plan imposed on a certain equipment exceeds the production capacity.

  The component equipment allocation device 10 includes a calculation unit 100, a storage unit 200, an input unit 300, and an output unit 400. The calculating part 100 controls the component equipment allocation process in this embodiment. The storage unit 200 stores data necessary for the component equipment allocation process. The input unit 300 is a device that receives an input operation from a user. The output unit 400 is a device that performs an output process of data stored in the component equipment allocation device 10.

  The arithmetic unit 100 includes an arithmetic processing unit 110 and a memory unit 120. The arithmetic processing unit 110 includes a data acquisition unit 111, an equipment load calculation unit 112, an equipment capacity determination unit 113, an equipment load movement man-hour ratio calculation unit 114, an equipment replacement assignment unit 115, and a display control unit 116. .

  The data acquisition unit 111 acquires data necessary for the component equipment allocation process from the memory unit 120, the input unit 300, or the storage unit 200.

  The equipment load calculation unit 112 calculates the load of each equipment using the information stored in the storage unit 200 or the intermediate information stored in the memory unit 120. The load of the facility is, for example, the operation time of the facility on a predetermined day. A method for calculating the load on the facility will be described in detail later.

  The facility capacity determination unit 113 compares the load of each facility calculated by the facility load calculation unit 112 with the manufacturing capability information 204, and the load of each facility to which the product is assigned is assigned to each manufacturing capability. Determine if it has exceeded.

  The equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio for each combination of equipment planned to be manufactured, equipment that can be replaced, and parts that are planned to be manufactured. The equipment load transfer man-hour ratio is an index (parameter) indicating an influence when substituting manufacturing of parts from a predetermined equipment to another equipment. The equipment load movement man-hour ratio calculation unit 114 is based on the number of shape elements, which is an index indicating the complexity of the product, the load when the equipment before replacement manufactures the product, and the unit CAM (Computer Aided Manufacturing) creation man-hour. The equipment load transfer man-hour ratio is calculated in detail.

  The equipment replacement allocating unit 115 identifies an alternative equipment for substituting for manufacturing and a part for substituting for manufacturing according to a process described later, based on the equipment load transfer man-hour ratio. In addition, the facility replacement assignment unit 115 updates the information reported to the storage unit 200 so as to assign the manufacture of the specified part to the specified replacement facility.

  The display control unit 116 generates information for displaying an equipment allocation execution screen that is a screen for starting alternative allocation of components. In addition, the display control unit 116 generates information for displaying the post-allocation display screen 230 that displays the allocation status after the production of parts is allocated to the alternative equipment. The display control unit 116 causes the output unit 400 to display each screen using the generated information.

  The memory unit 120 temporarily stores information generated by the arithmetic processing unit 110. The memory unit 120 temporarily stores intermediate information, which is information generated between the start of a component equipment allocation process and an alternative allocation process, which will be described later, until a predetermined information is output. In the memory unit 120, for example, facility load pile information 207, facility load accumulated information 208, and facility load movement man-hour ratio information 209 are stored.

  The storage unit 200 stores part information 201, manufacturing plan information 202, equipment replacement information 203, manufacturing capacity information 204, parts equipment allocation information 205, and CAM creation instruction information 206. The storage unit 200 stores part information 201, manufacturing plan information 202, facility replacement information 203, and manufacturing capability information 204 as input information in advance before the processing in the present embodiment is started. When the processing in the present embodiment is started, the storage unit 200 stores component equipment allocation information 205 and CAM creation instruction information 206 as output information.

  The parts information 201 is information regarding parts manufactured in a facility having each equipment. The component information 201 includes the shape of each component and the time required for each facility when manufactured by facilities in the factory.

  FIG. 2 is a diagram illustrating an example of the component information 201. The component information 201 is information in which a component name 201b, a shape element number 201c, a facility 201d, and a required time 201e are associated with a component ID (Identification) 201a that is component identification information for identifying a component. It is.

  The component ID 201a is identification information uniquely defined for each component. The part name 201b is the name of the part.

  The shape element number 201c is a numerical value serving as an index indicating the complexity of the part. The shape element number 201c is data acquired from, for example, CAD (Computer Aided Design), and indicates the number of lines, holes, and the like for specifying the shape of the component. The larger the value of the shape element number 201c, the larger the CAM creation man-hour.

  The equipment 201d is equipment capable of manufacturing parts. The required time 201e is a time required when a part is manufactured by the equipment 201d, and is indicated in units of “minute”, for example.

  This figure shows that, for example, when the part ID 201a is “P01” and the shape element number 201c is “15” and the equipment 201d is produced with “equipment A”, the time required for the production is 11.7 minutes. This is shown. Similarly, when a part having the same part ID “P01” is manufactured by “equipment B”, the manufacturing takes 20 minutes.

  Returning to FIG. The production plan information 202 is information for managing a production schedule facility to which each part is produced, a production number, and production of the parts are assigned.

  FIG. 3 is a diagram illustrating an example of the manufacturing plan information 202. The production plan information 202 is information in which an allocation facility 202b, a production quantity 202c, and a scheduled input date 202d are associated with each part ID 202a that identifies a part to be manufactured.

  The component ID 202a is identification information for identifying a component, and corresponds to the component ID 201a of the component information 201. The allocation facility 202b is information for identifying a facility allocated to a component, that is, a facility where the manufacture of the component is scheduled. The production number 202c is the number of parts produced by the allocation equipment 202b. The scheduled input date 202d is a date on which a part is scheduled to be input, and indicates that the part is manufactured on that date.

  The production plan information 202 is information at the planning stage, and the parts allocation facility 202b specified in the production plan information 202 is provisionally determined by the presence or absence of CAM data at the time of planning, the production time, and the like. It is what was done. Therefore, depending on the load status of each facility, it is changed and assigned to another facility by a process described later.

  Returning to FIG. The equipment replacement information 203 is information for managing whether or not equipment can be replaced and the CAM creation man-hour at the time of replacement.

  FIG. 4 is a diagram illustrating an example of the equipment replacement information 203. The equipment replacement information 203 is information that associates the availability of replacement with the unit CAM creation man-hours for each combination of equipment. The equipment replacement information 203 includes a pre-change equipment 203a, a post-change equipment 203b, a substitution possibility 203c, and a unit CAM creation man-hour 203d.

  The pre-change equipment 203a is one equipment managed by the parts equipment assignment device 10. The post-change equipment 203b is equipment other than the pre-change equipment 203a. Note that the facility replacement information 203 has a record different from the combination in which the pre-change equipment 203a and the post-change equipment 203b are positive even if the pre-change equipment 203a and the post-change equipment 203b are reversed. Yes. For example, the equipment replacement information 203 includes information indicating that the equipment 203a before the change is "equipment A" and the equipment 203b after the change is "equipment B", the equipment 203a before the change is "equipment B", and the equipment 203b after the change is "equipment" A ”is also included. This is the same even when the equipment A is a higher model than the equipment B, for example.

  The substitution possibility 203c is information indicating whether or not substitution of production from the pre-change equipment 203a to the post-change equipment 203b is possible. The unit CAM creation man-hour 203d is a man-hour for creating CAM data required per one shape element, which is generated when the pre-change equipment 203a is replaced with the post-change equipment 203b.

  Here, the CAM creation man-hour will be described. In order to make the equipment manufacture parts, it is necessary to create CAM data that is a machining program for machine tools. CAM data is necessary data for a combination of equipment and parts. Therefore, it is conceivable that CAM data is held in advance for all combinations of facilities and products managed by the component equipment allocation device 10. However, if CAM data is created for all combinations, the number of man-hours for creating CAM data becomes enormous. Therefore, it is usually desirable to create CAM data limited to the required CAM data.

  If the planned production facility has a CAM for the production of specified parts, it will be used in the planned replacement facility due to the commonality of the facility capacity between the planned production facility and the planned replacement device, the similarity of tools, etc. In some cases, the number of man-hours required to create a CAM can be reduced. For this reason, in the equipment replacement information 203, in addition to whether or not the equipment can be replaced, the number of man-hours for creating a CAM generated during the replacement is managed. The unit CAM creation man-hour is a CAM creation man-hour per number of shape elements described later.

  For example, in the case of FIG. 4, when the equipment 203a before change is "equipment A" and the equipment 203b after change is "equipment B", the alternative is "possible", and the unit CAM creation man-hour 203d at that time is "6" It is shown that. Further, when the pre-change equipment 203a is "equipment A" and the post-change equipment 203b is "equipment C", the alternative is "possible", and the unit CAM creation man-hour 203d at that time is "12". Therefore, it is shown that when the “equipment A” is replaced with the “equipment B”, the replacement can be performed with half the number of CAM creation man-hours as compared with the case where the “facility C” is replaced.

  The production capacity information 204 is information indicating the upper limit value of the load of each facility, and includes the operating time of each facility per day.

  FIG. 5 is a diagram illustrating an example of the manufacturing capability information 204. The production capability information 204 is information in which the processing capability 204b is associated with the facility 204a.

  The facility 204a is information for identifying a facility that is managed by the component facility allocation apparatus 10. The processing capacity 204b is a value indicating the processing capacity of the facility. The processing capacity 204b is, for example, the time during which the facility can operate per day. The processing capacity 204b may be the number of parts that can be processed per day, etc., and may be of any type as long as the value indicates the upper limit value of the load on the equipment.

  Returning to FIG. The parts equipment allocation information 205 is information for managing the parts to be assigned to each equipment and the load applied to the equipment when the parts are manufactured for each scheduled input date.

  FIG. 6 is a diagram illustrating an example of the component equipment allocation information 205. The component facility allocation information 205 is information in which the allocated facility 205b, the facility load 205c, and the scheduled input date 205d are associated with each other for each component ID 205a that identifies the component to be manufactured.

  The component ID 205 a is identification information that identifies a component to be manufactured, and corresponds to the component ID 201 a of the component information 201. The allocation facility 205 b is information for identifying the facility to which the part ID 201 a is allocated for manufacturing, and corresponds to the allocation facility 202 b of the manufacturing plan information 202. The equipment load 205c is information indicating the load applied to the assigned equipment 205b when the component ID 201a is manufactured by the assigned equipment 205b. The equipment load 205c is, for example, the time taken when the assigned equipment 205b manufactures the component ID 205a. The scheduled input date 205d is a date on which the part ID 205a is scheduled to be input, and corresponds to the scheduled input date 202d of the manufacturing plan information 202.

  FIG. 6 shows that, for example, a part whose part ID 205a is “P01” is manufactured by the allocation equipment 205b “equipment A” on the scheduled input date 205d “2013/07/01”, and the time required for “equipment A” at that time is shown. “3.5” hours.

  Returning to FIG. 1, the CAM creation instruction information 206 includes a pre-change facility, a post-change facility, a component to be replaced, and a scheduled input date to be replaced when a component to be replaced and a replacement facility are specified. It is information for managing. Based on the CAM creation instruction information 206, creation of CAM data of parts to be manufactured for each alternative facility is instructed.

  FIG. 7 is a diagram illustrating an example of the CAM creation instruction information 206. The CAM creation instruction information 206 is information in which a pre-change equipment 206b, a post-change equipment 206c, and a scheduled input date 206d are associated with each part ID 206a of a part to be manufactured.

  The component ID 206a is identification information that identifies a component that is to be replaced, and corresponds to the component ID 201a of the component information 201. The pre-change equipment 206b is equipment for which the production of the component ID 206a is scheduled, and is information for specifying the equipment before the production is replaced. The post-change equipment 206c is information for specifying an alternative equipment that substitutes the production of the component ID 206a from the pre-change equipment 206b. The scheduled loading date 206d is information indicating the date on which the component ID 206a is scheduled to be loaded into the changed facility 206c.

  For example, in FIG. 7, for the part whose part ID 206a is “P02”, the assignment is changed from the pre-change equipment 206b “equipment A” to the post-change equipment 206c “equipment B”, and the scheduled input date 206d “2013/07/01” Indicates that the input is scheduled. Therefore, it is necessary to additionally create CAM data for manufacturing the component ID “P02” with “facility B”.

  Next, information generated at an intermediate stage of processing in the present embodiment will be described. In the intermediate stage, facility load pile information 207, facility load accumulated information 208, and facility load movement man-hour ratio information 209 are generated and temporarily stored in the memory unit 120, respectively.

  FIG. 8 is a diagram illustrating an example of the equipment load pile information 207. The equipment load pile information 207 is intermediate information generated at the time of component equipment assignment processing, and is temporarily stored in the memory unit 120.

  The equipment load pile information 207 is information in which the load of the assigned equipment is associated with each part for which the production plan is made by the production plan information 202. The equipment load stacking information 207 is information in which the assigned equipment 207b, the equipment load 207c, and the scheduled input date 207d are associated with the component ID 207a.

The allocation facility 207 b is information for specifying a facility scheduled to be manufactured with the component ID 207 a and corresponds to the allocation facility 202 b of the manufacturing plan information 202.

  The equipment load 207c is information indicating the load applied to the assigned equipment 207b when the component ID 207a is manufactured by the assigned equipment 207b. The facility equipment 207b is, for example, an operation time when the assigned equipment 207b manufactures a part specified by the part ID 207a.

  The scheduled input date 207d is information indicating the date on which the component ID 207a is scheduled to be input to the assigned equipment 207b.

  FIG. 9 is a diagram illustrating an example of the facility load cumulative information 208. The equipment load accumulation information 208 is information indicating the accumulation of the equipment loads of the equipment whose production is planned in the production plan information 202 on the scheduled introduction date. The equipment load accumulation information 208 is information in which the equipment load 208b and the scheduled input date 208c are associated with each equipment 208a.

  The facility 208 a is information for identifying a facility for manufacturing a part, and corresponds to the allocated facility 202 b of the manufacturing plan information 202. The equipment load 208b is information indicating the load on the scheduled date 208c of the equipment 208a. The equipment load 208b is, for example, the total operating time on the scheduled date 208c of the equipment 208a. The scheduled input date 208c is a date on which the facility 208a is scheduled to operate.

  FIG. 10 is a diagram illustrating an example of the equipment load movement man-hour ratio information 209. The equipment load transfer man-hour ratio is a value calculated for a combination of parts, equipment before change, and equipment after change. Therefore, in the equipment load movement man-hour ratio information 209, the equipment load movement man-hour ratio 209d is associated with the component ID 209a, the pre-change equipment 209b, and the post-change equipment 209c.

The pre-change equipment 209 b is information for specifying the equipment to which the part related to the part ID 202 a is assigned in the production plan information 202, and corresponds to the assigned equipment 202 b in the production plan information 202.

  The post-change facility 209c is information that identifies a facility that is a candidate for substituting manufacturing from the pre-change facility 209b for the component related to the component ID 202a. The equipment load movement man-hour ratio 209d is a parameter indicating the movement load when the production of the part related to the part ID 209a is replaced from the pre-change equipment 209b to the post-change equipment 209c. Details of the calculation method and the like will be described later.

Hereinafter, regarding each day of the period in which the input is received in the target period input area 221, it is determined whether or not the facility allocation is necessary, and when it is determined that it is necessary, a process of allocating alternative facilities for a predetermined day is performed. Note that the target period input area 221 may accept designation of a date to which an alternative facility is allocated instead of designation of a period composed of a start date and an end date.

  The execution button 222 is a button for confirming the target period input in the target period input area 221. The maintenance button 223 is a button for performing maintenance of the component information 201, the manufacturing plan information 202, the equipment replacement information 203, and the manufacturing capability information 204 stored in the storage unit 200.

In step S10, when the target period is input to the target period input area 221 of the equipment allocation execution period and the execution button 222 is selected, the data acquisition unit 111 includes the component information 201, the production plan information 202 of the target period, The equipment replacement information 203 and the production capability information 204 are called from the storage unit 200 (step S12).

  Next, the facility load calculation unit 112 identifies a date (calculation date) q for facility allocation in the target period (step S14). Here, the sum of the calculation dates included in the target period is set as r day, and the calculation date q is specified in ascending order of dates, for example. First, the following processing is performed with q = 1.

  Next, the equipment load calculation unit 112 calculates the equipment load for each component, and generates equipment load pile information 207 (step S16). Specifically, the equipment load calculation unit 112 reads out the part ID 202a and the assigned equipment 202b that correspond to the calculation date specified in step S14 and the scheduled input date 202d of the production plan information 202. The equipment load calculation unit 112 refers to the part information 201 using the read part ID 202a and the assigned equipment 202b, and the required time of the record in which the part ID 202a and the part ID 201a correspond and the assigned equipment 202b and the equipment 201d correspond. 201e is read. Next, the facility load calculation unit 112 calculates the facility load by multiplying the read required time 201e and the number of manufactured products 202c of the manufacturing plan information 202. The equipment load calculation unit 112 calculates the equipment load for each part that is scheduled to be manufactured on the calculation date specified in step S <b> 14, and generates equipment load pile information 207.

  For example, when “2013/07/01” is specified as the calculation date in step S14, the facility load calculation unit 112 refers to the production plan information 202, and a record in which the estimated input date 202d is “2013/07/01”. As a result, a record in which the component ID 202a is “P01”, the assigned equipment 202b is “equipment A”, and the production number 202c is “18” is read. Next, the facility load calculation unit 112 refers to the component information 201 and reads the required time 201e “11.7 (minutes)” of the record in which the component ID 201a is “P01” and the facility 201d is “equipment A”. Next, the facility load calculation unit 112 calculates the facility load “3.51 (hours)” by multiplying the required time “11.7 (minutes)” by the number of manufactured products “18”. Next, the equipment load calculation unit 112 sets the part ID 207a of the equipment load stacking information 207 to “P01”, the assigned equipment 207b to “equipment A”, the equipment load 207c to “(about) 3.5”, and the scheduled input date 207d to “ 2013/07/01 ", the equipment load pile information 207 is generated.

  Next, the facility load calculation unit 112 sums the facility loads on the calculation date for each facility, and generates facility load cumulative information 208 (step S18). Specifically, the equipment load calculation unit 112 refers to the equipment load pile information 207, adds up the equipment loads 207c for each assigned equipment 207b of the equipment load pile information 207, and generates equipment load accumulated information 208.

  For example, in the equipment load pile information 207 shown in FIG. 8, the assigned equipment 207 b totals the equipment loads 207 c of the records of “facility A”, thereby calculating “14 (time)”. The equipment load calculation unit 112 sums up the equipment loads for each equipment, for example, generates the equipment load accumulated information 208 shown in FIG. 9 and stores it in the memory unit 120.

  Next, the facility capacity determination unit 113 compares the facility load accumulated information 208 and the manufacturing capacity information 204 to determine whether there is an overcapacity facility (step S20). Specifically, the facility capacity determination unit 113 determines whether the facility load 208 b exceeds the processing capacity 204 b of the manufacturing capacity information 204 for each facility 208 a stored in the accumulated facility load information 208.

  When the equipment capacity determination unit 113 determines that there is an equipment in which the equipment load 208b exceeds the processing capacity 204b of the manufacturing capacity information 204 (in the case of “YES” in step S20), the equipment capacity determination unit 113 sets the equipment over capacity capacity. The parts assigned to the part are extracted (step S22). Specifically, the facility capacity determination unit 113 refers to the manufacturing plan information 202 and extracts assigned parts for facilities whose facility load 208b exceeds the processing capacity 204b.

  For example, in the equipment load cumulative information 208 of FIG. 9, the equipment 208a having “equipment A” and “equipment D” exceeds the processing capacity “8 (hours)”. The facility capability determination unit 113 refers to the production plan information 202 and extracts the component IDs 202a of all the components assigned to “facility A” and “facility D”.

  Next, the arithmetic processing unit 110 identifies equipment for substituting for one of the components extracted in step S22, and performs an allocation process (step S24).

  FIG. 13 is a flowchart showing the flow of alternative allocation processing. Before this processing is started, one or a plurality of facilities that exceed the processing capacity on a predetermined scheduled input date and parts assigned to the facilities are extracted.

  First, the facility substitution allocating unit 115 identifies one facility among the overcapacity facilities (step S241). The specified over-capacity equipment is set as m, and the over-capacity equipment is specified in order until m reaches the total number of over-capacity equipment n, and the following processing is performed. In the following description, it is assumed that “facility A” is specified.

  Next, the equipment load movement man-hour ratio calculation unit 114 extracts the replaceable equipment and the unit CAM creation man-hours for the equipment specified in Step S241 (Step S243). Specifically, the equipment load movement man-hour ratio calculation unit 114 refers to the equipment replacement information 203 using information for specifying the overcapacity equipment, and the substitute availability 203c is “ The post-change equipment 203b that is “possible” and the unit CAM creation man-hour 203d are extracted. When there are a plurality of post-change equipment 203b whose substitution possibility 203c is “permitted”, all the post-change equipment 203b is extracted in association with the unit CAM creation man-hour 203d. Hereinafter, the extracted post-change equipment will be described as alternative equipment.

  Explaining in the above example, the equipment load movement man-hour ratio calculating unit 114 corresponds to “equipment A” in the equipment substitution information 203 and creates a changeable equipment “equipment B” having a substitution possibility 203c of “possible” and a unit CAM. Man-hours 203d "6", "equipment C" and "12", "equipment D" and "15" are extracted in association with each other.

  Next, the equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio for each component assigned to the equipment specified in step S241 (step S245). The equipment load transfer man-hour ratio is an index calculated for each combination of equipment scheduled to be manufactured, substitutable equipment, and parts assigned to the equipment to be manufactured. The equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio when manufacturing is assigned to each of the substitutable equipment extracted in step S243 for each part assigned to the overcapacity equipment.

  The equipment load movement man-hour ratio is an index (parameter) indicating the impact of substituting parts production from overcapacity equipment to substitutable equipment, that is, the movement load. It is calculated on the basis of the unit CAM creation man-hour generated at the time and the equipment load when the equipment before change manufactures the part. The calculation formula for calculating the equipment load movement man-hour ratio is as follows.

The equipment load movement man-hour ratio E _{i, j, k} calculated in the above (Equation 1) indicates the movement load when the production of the component i is replaced from the equipment j to the replaceable equipment k. The larger the equipment load movement man-hour ratio, the greater the load associated with the movement.

Each parameter of (Equation 1) will be described. _Pi is the number of shape elements of the part i. M _{j, k} is a unit CAM creation man-hour when changing the allocation from the equipment j to the equipment k. h represents one component, and T _{i, j, h} represents the required time (load) in the equipment j per component i.

  The denominator of (Expression 1) indicates a load applied to the equipment j when the part i is manufactured in the equipment j. The larger the denominator, the greater the production load of the product in the facility before replacement, and it is more efficient at the time of replacement to substitute the other facilities for the manufacture of parts with a large production load.

  The numerator of (Equation 1) is a parameter indicating the CAM creation man-hour required for allocating the part i from the equipment j to the equipment k, and has the number of shape elements indicating the complexity of the shape of the part i and the equipment before and after the substitution. It is calculated by the product of CAM creation man-hours per unit element, which occurs due to differences in tools and the like. In addition, the numerator of (Equation 1) indicates that more CAM creation man-hours occur when the part shape is complicated and the tools of the facilities before and after replacement have no commonality.

  FIG. 14 is a diagram showing the concept of the facility load movement man-hour ratio. In the facility A, the facility load when manufacturing the part “P01” is “210 (minutes)”, and the number of shape elements of the part “P01” is “15”. Further, from the equipment replacement information 203 in FIG. 4, the unit CAM creation man-hour when the manufacturing is replaced from the equipment A to the equipment B is “6”. Therefore, the equipment load transfer man-hour ratio when replacing the part “P01” from the equipment A to the equipment B is “about 0.43” from “15 × 6/210”.

  Similarly, the equipment load transfer man-hour ratio when replacing the part “P01” from the equipment A to the equipment C is “approximately 0.86” from “15 × 12/210”, and the part “P02” is installed from the equipment A to the equipment A. The ratio of man-hours for moving the equipment load when substituting for B is “10 × 6/150 = 0.4”.

  In the present embodiment, the load associated with the substitution including the CAM creation man-hour is further increased by preferentially substituting the manufacturing for the combination of the over-capacity equipment (scheduled production equipment), the substitutable equipment, and the parts with a small equipment load movement man-hour ratio. Keep it low.

  In the above example, the parts “P01”, “P02”, “P03”, “P04”, “P05”, and “P06” are assigned to the overcapacity equipment “equipment A” (from the production plan information 202). The equipment load movement man-hour ratio calculation unit calculates the replaceable equipment “equipment B” “equipment C” “equipment” extracted in step S243 for each of the parts “P01” “P02” “P03” “P04” “P05” “P06”. The ratio of the man-hours for moving the equipment load to each of “D” is calculated.

  The equipment load movement man-hour ratio calculation unit 114 stores the calculated equipment load movement man-hour ratio in the memory unit 120. For example, as the equipment load movement man-hour ratio information 209 illustrated in FIG. 10, the memory unit 120 includes a part ID of a component that is a basis for calculating the equipment load movement man-hour ratio, the equipment before change, the equipment after change, and the calculated equipment load. A record in which the movement man-hour ratio is associated is generated.

  Returning to FIG. Next, the equipment load movement man-hour ratio calculation unit 114 determines whether m = n (step S247). The fact that m = n means that the equipment load transfer man-hour ratio between the assigned part and the replaceable equipment has been calculated for all the overpowered equipment determined to exceed the processing capacity in step S18. Is shown.

  If the equipment load movement man-hour ratio calculation unit 114 does not determine that m = n (“NO” in step S247), the equipment load movement man-hour ratio calculation unit 114 increments m (step S249). Thereafter, the equipment load movement man-hour ratio calculation unit 114 returns the process to step S243.

  When the equipment load movement man-hour ratio calculation unit 114 determines that m = n (in the case of “YES” in step S247), the equipment replacement allocation unit 115 determines that the equipment load movement man-hour ratio is the smallest component / capacity excess equipment. A combination of substitutable equipment is extracted, the extracted substitutable equipment is specified as a replacement candidate equipment, and the extracted part is specified as a replacement candidate part (step S251).

  For example, referring to the equipment load movement man-hour ratio 209d in the example of FIG. 10, the equipment load movement man-hour ratio “0.4” when substituting the production of the part “P02” from “equipment A” to “equipment B” is the smallest. is there. Therefore, the facility replacement allocation unit 115 identifies “installation B”, which is a replaceable facility, as a replacement candidate facility and the component “P02” as a replacement candidate component.

  Returning to FIG. Next, the equipment replacement allocation unit 115 calculates the total equipment load of the replacement candidate equipment (step S253). Specifically, the equipment replacement assignment unit 115 calculates the total equipment load when the replacement candidate parts are assigned to the replacement candidate equipment.

  To explain using the above example, the equipment load before the substitute candidate part “P02” is assigned to “equipment B” of the alternative candidate equipment is “2” according to the equipment load cumulative information 208 of FIG. The equipment replacement allocating unit 115 calculates the equipment load when the part “P02” is manufactured by the “equipment B”. The value calculated here is the required time “when the part“ P02 ”is manufactured by the“ equipment B ”to the manufacturing number“ 25 ”of the part“ P02 ”(extracted from the manufacturing number 202c of the manufacturing plan information 202)”. "3.75 (hours)" obtained by multiplying by "9.0 (minutes)" (extracted from the required time 201e of the component information 201). The equipment replacement allocating unit 115 adds the load “3.75” at the time of manufacturing the replacement candidate part to the initial equipment load “2” to obtain the total equipment load “5.75”.

  Next, the equipment replacement allocation unit 115 determines whether or not the total equipment load of the replacement candidate equipment is within the processing capacity (step S255). Specifically, the facility replacement allocating unit 115 compares the total facility load calculated in step S253 with the processing capability of the manufacturing capability information 204, and determines whether the total facility load is within the processing capability.

  In the above example, the equipment replacement allocating unit 115 determines that the total equipment load “5.75” of “facility B” of the alternative candidate equipment is within the processing capacity “8” of “facility B” of the manufacturing capacity information 204. judge.

  If the facility replacement allocation unit 115 determines that the total facility load of the replacement candidate facility is within the processing capacity (“YES” in step S255), the facility replacement allocation unit 115 changes the production plan information 202 ( Step S257). Specifically, the facility replacement allocation unit 115 identifies the replacement candidate facility as the replacement facility, and rewrites the allocation facility 202b associated with the component ID 202a corresponding to the replacement candidate component in the production plan information 202 with the replacement facility. Thereby, the production of the alternative candidate parts is assigned to the alternative equipment.

  Next, the equipment replacement assignment unit 115 generates CAM creation instruction information 206 (step S259). Specifically, the equipment replacement allocation unit 115 replaces the replacement candidate part with the part ID 206a in the CAM creation information, the pre-change equipment with the original replacement candidate part assigned to the pre-change equipment 206b, and the replacement candidate with the post-change equipment 206c. For the equipment, information is generated that associates the planned input date with which the parts are scheduled to be input in the manufacturing plan information 202 with the planned input date 206d. Thereafter, the equipment substitution allocating unit 115 advances the process to step S16. In subsequent step S16, facility load pile information 207 is generated based on the production plan information 202 changed in step S257.

  If the equipment replacement allocation unit 115 does not determine that the total equipment load of the replacement candidate equipment is within the processing capacity (in the case of “NO” in step S255), the equipment replacement allocation unit 115 then determines that the equipment load transfer man-hour ratio is A combination of small parts, overcapacity equipment, and substitutable equipment is extracted, and the substitutable equipment is specified as a substituting candidate equipment, and the part is specified as a substituting candidate part (step S261).

  In the above example, if the part “P02” is replaced with “equipment B” and the total equipment load of “equipment B” exceeds the processing capacity “8”, the equipment replacement assignment unit 115 Extract a combination with a small moving man-hour ratio. In FIG. 10, the equipment load transfer man-hour ratio is the next smallest value “0.42” when the part “P09” is replaced from “equipment D” to “equipment E”. , “Equipment E” is identified as an alternative candidate facility, and part “P09” is identified as an alternative candidate part.

  After that, the facility replacement assignment unit 115 returns the process to step S253.

  Returning to FIG. In step S20, if the equipment capacity determination unit 113 does not determine that there is an equipment whose equipment load 208b exceeds the processing capacity 204b of the manufacturing capacity information 204 (in the case of “NO” in step S20), the equipment capacity determination unit 113 It is determined whether or not the calculation date q is equal to r (step S26). The case where the calculation date q is equal to r is a case where parts are allocated to each facility so as to be within the processing capacity for all schedules included in the target period for which designation is accepted on the facility allocation execution screen 220.

  If the facility capability determination unit 113 does not determine that the calculation date q is equal to r (“NO” in step S26), the facility capability determination unit 113 increments q (step S28). Thereafter, the equipment capability determination unit 113 returns the process to step S14.

  When the equipment capacity determination unit 113 determines that the calculation date q is equal to r (in the case of “YES” in step S26), the equipment load calculation unit 112 determines that the part is based on the manufacturing plan information 202 and the part information 201. Equipment allocation information 205 is generated (step S30). Specifically, the equipment load calculation unit 112 calculates the equipment load by multiplying the number of manufactured parts 202c and the required time 201e in the parts information 201 for each part ID 202a of the manufacturing plan information 202. The equipment load calculation unit 112 plans to input the part ID 202a of the manufacturing plan information 202 to the part ID 205a, the assigned equipment 202b to the assigned equipment 205b, the calculated equipment load to the equipment load 205c, and the scheduled input date 202d of the manufacturing plan information 202. A record corresponding to each day 205d is generated, and the component equipment allocation information 205 is generated.

  Note that the equipment load pile information 207 generated in step S16 immediately before it is determined as “NO” in step S20 is in common with the component equipment allocation information generated in step S28.

  Next, the display control unit 116 outputs the post-assignment display screen 230 (step S32). In the alternative facility allocation process in step S24, CAM creation instruction information 206 is generated in which the parts to be replaced are associated with the equipment before the change and the alternative equipment after the change. Based on the CAM creation instruction information 206, the display control unit 116 generates display information for displaying the replacement equipment after the change and the part to be replaced on the display screen 230 after the assignment, and outputs the display information via the display unit. . Then, the process of this flowchart is complete | finished.

  FIG. 16 is a diagram illustrating an example of the post-assignment display screen 230. The post-assignment display screen 230 includes a scheduled date input area 231, a component equipment assignment display area 232, a CAM creation instruction display area 233, and an equipment load display area 234. The information displayed on the post-assignment display screen 230 is information after the part assignment is changed from the pre-change equipment to the alternative equipment. The information displayed on the post-assignment display screen 230 may be any one of the information displayed on the part equipment assignment display area 232, the CAM creation instruction display area 233, or the equipment load display area 234. Also, a combination of two of these may be used.

  The scheduled input date input area 231 is an area for inputting a date on which a part is scheduled to be input. In the planned launch date display area, the planned launch date can be selected from a drop-down list, for example. When the planned introduction date is input in the planned planned date input area 231, the display control unit 116 stores the component equipment allocation information, the CAM creation instruction information, and the equipment load information on the input planned planned date in each area. Display.

  In the parts facility allocation display area 232, the parts to be input on the scheduled input date and the allocated facilities to which the parts are allocated are displayed in association with each other. The display control unit 116 refers to the production plan information 202, and identifies the part ID 202a and the assigned equipment 202b for the record corresponding to the planned input date and the planned input date 202d input in the planned input date input area 231. The display control unit 116 associates the identified part ID 202a with the assigned equipment 202b and generates display information to be displayed in the part equipment assigned display area 232.

  In the CAM creation instruction display area 233, the parts that have been replaced by the manufacturing and the facilities that are contracted for manufacturing after the replacement are displayed in association with each other. The display control unit 116 refers to the CAM creation instruction information 206, and identifies the part ID 206a and the post-change equipment 206c for the record corresponding to the planned input date and the planned input date 206d input in the planned input date input area. The display control unit 116 associates the identified component ID 206a with the changed equipment 206c and generates display information to be displayed in the CAM creation instruction display area. By browsing the CAM creation instruction display area 233, it is possible to grasp in a list which CAM data corresponding to which equipment should be generated for a part to be manufactured.

  The equipment load display area 234 is an area for displaying the load imposed on the scheduled introduction date for each piece of equipment managed by the component equipment assignment apparatus 10. The display control unit 116 refers to the equipment load cumulative information 208, and uses the equipment load of each equipment on the planned entry date input area to enter the display information of the screen displayed in the equipment load display area 234. Generate.

  The equipment load display area 234 may be displayed, for example, as a bar graph in which each equipment is arranged on the horizontal axis and the load on each equipment is on the vertical axis. Thereby, the load imposed on each equipment can be grasped in a list. Further, by displaying the upper limit value of the processing capacity of each facility with a bold line, it is possible to grasp the situation in which each facility is assigned to manufacture without exceeding the processing capacity.

  According to the present embodiment, when manufacturing is replaced from equipment that exceeds the processing capacity to other equipment, it is possible to identify alternative equipment and parts that are less affected by the replacement. Thereby, manufacture of components can be replaced with other equipment more efficiently.

(First modification)
Next, a first modification will be described. In the above-described embodiment, the substitute equipment is determined by calculating the equipment load transfer man-hour ratio for all the parts allocated to the overcapacity equipment. In the first modified example, the production of parts is preferentially substituted by the other equipment from the equipment with less alternative equipment among the overcapacity equipment. Hereinafter, differences from the above-described embodiment will be described, and description of overlapping points will be omitted.

  FIG. 17 is a flowchart showing the flow of component equipment assignment processing in the first modification. The processing from step S10 to step S20 is the same as in the above-described embodiment. First, the data acquisition unit 111 receives an execution instruction specifying the target period (step S10). Next, the data acquisition unit 111 calls the part information 201, the manufacturing plan information 202, the equipment replacement information 203, and the manufacturing capability information 204 (step S12). Next, the facility load calculation unit 112 specifies a calculation date during the target period (step S14). Next, the equipment load calculation unit 112 calculates the equipment load for each component, and generates equipment load pile information 207 (step S16). Next, the equipment load calculation unit 112 sums up the equipment loads for each part, and generates equipment load cumulative information 208 (step S18). Next, the facility capacity determination unit 113 compares the facility load accumulated information 208 and the manufacturing capacity information 204 to determine whether there is an overcapacity facility (step S20).

  In step S20, when the equipment capacity determination unit 113 determines that there is equipment whose equipment load 208b exceeds the processing capacity 204b of the manufacturing capacity information 204 (in the case of “YES” in step S20), the equipment capacity determination unit 113 With reference to the substitute information 203, the facility with the least replaceable facility among the overcapacity facilities is identified (step S21).

  Specifically, the facility capacity determination unit 113 refers to the replacement possibility 203c associated with the pre-change equipment 203a corresponding to the overcapacity equipment for each of the overcapacity equipments, and the record in which the replacement possibility 203c is “possible”. Count the number of The facility capacity determination unit 113 identifies the overcapacity facility with the smallest number of records in which the substitution possibility 203c is “possible”. In addition, when there are a plurality of overcapacity facilities having the same number of records that are “permitted”, any overcapacity facility may be specified.

  The processing performed from step S22 to step S32 is the same as that in the above-described embodiment. The equipment capacity determination unit 113 extracts the parts assigned to the over capacity equipment (step S22). Next, each processing unit in the arithmetic processing unit 110 performs allocation to an alternative facility (step S24). In step S20, if the facility capacity determination unit 113 compares the facility load accumulated information and the manufacturing capacity information and determines that there is no overcapacity facility (in the case of “NO” in step S20), the facility capacity determination unit 113 Then, it is determined whether or not the calculation date q is equal to r (step S26). If the facility capacity determination unit 113 does not determine that the calculation date q is equal to r (“NO” in step S26), the facility capacity determination unit 113 increments q (step S28). If the equipment capacity determination unit 113 determines that the calculation date q is equal to r (“YES” in step S26), the equipment load calculation unit 112 generates the part equipment allocation information 205 (step S30). Next, the display control unit 116 outputs the post-assignment display screen 230. Then, the process of this flowchart is complete | finished.

  FIG. 18 is a flowchart showing the flow of alternative assignment processing in the first modification. In the first modification, since one of the overcapacity facilities has already been specified, the process of step S241 is not required. Note that the processing performed from step S243 to step S245 is the same as in the above-described embodiment.

  In step S243, the equipment load movement man-hour ratio calculation unit 114 extracts a replaceable equipment and a unit CAM creation man-hour for each part assigned to the overcapacity equipment specified in step S19.

  In step S245, the equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio for each part allocated to the overcapacity equipment specified in step S19.

  In the first modified example, since the specified overcapacity facility is replaced with another facility, there is no need to calculate the facility load transfer man-hour ratio for all the overcapacity facilities at this stage. Therefore, in the first modification, the processes in steps S247 and S249 in the above-described embodiment are not required.

  Processing performed between step S251 and step S261 is the same as that in the above-described embodiment. The equipment replacement allocation unit 115 extracts a combination of a part, an overcapacity equipment, and a substitutable equipment having the smallest equipment load transfer man-hour ratio, and specifies a replacement candidate equipment and a replacement candidate part (step S251). Next, the equipment replacement allocation unit 115 calculates the equipment load of the replacement candidate equipment (step S253). Next, the equipment replacement allocation unit 115 determines whether or not the equipment load of the replacement candidate equipment is within the processing capacity (step S225). If the equipment replacement allocation unit 115 determines that the equipment load of the replacement candidate equipment is within the processing capacity (“YES” in step S225), the equipment replacement allocation unit 115 changes the production plan information 202 (step S225). S257). Next, the facility substitution allocation unit 115 generates CAM creation instruction information 106 (step S259). The equipment replacement allocating unit 115 thereafter ends the process of this flowchart. If the equipment replacement assignment unit 115 does not determine that the equipment load of the replacement candidate equipment is within the processing capacity (“NO” in step S225), the equipment replacement assignment unit 115 has the next smallest equipment load movement man-hour ratio. A combination of parts, overcapacity equipment and substitutable equipment is extracted, and alternative candidate equipment and alternative candidate parts are identified (step S261).

  The equipment load transfer man-hour ratio does not consider the number of equipment that can be replaced in the overcapacity equipment.As a result of assigning to the substitute equipment in ascending order of the equipment load transfer man-hour ratio, the overcapacity equipment that does not have a replacement destination is not replaced May remain. For this reason, in the 1st modification, substitution of manufacture to other equipment is performed preferentially from the overcapacity equipment with few substituteable equipment. As a result, the facility load can be further leveled and the production can be allocated to the alternative facility.

(Second modification)
Next, a second modification will be described. In the second modification, the component information 201 includes information indicating the presence / absence of a CAM. The equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio using a predetermined coefficient when the replaceable equipment has a CAM for a part.

  FIG. 19 is a diagram illustrating an example of the component information 201 in the second modification. The component information 201 includes a component ID, a component name, the number of shape elements, equipment, and a required time, as well as a CAM presence / absence 201f.

  The CAM presence / absence 201f is information specifying the presence / absence of a CAM. When the presence / absence of the CAM 201f is “present”, it indicates that the CAM data for manufacturing the part related to the part ID with the equipment associated with the CAM presence / absence 201f already exists.

  As described above, the CAM data is a machining program for causing a certain facility to manufacture a part. Therefore, when CAM data associated with an equipment and a product already exists, it is not necessary to generate CAM data when substituting the equipment for manufacturing the product.

  When calculating the equipment load movement man-hour ratio, the equipment load movement man-hour ratio calculating unit 114 calculates the unit CAM creation man-hours when CAM data corresponding to a combination of substitutable equipment and parts as a basis of calculation exists. Multiply by a predetermined factor. For example, the equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio by multiplying the unit CAM creation man-hour by a coefficient “0”. As a result, manufacturing can be preferentially substituted for a combination of parts having CAM data and substitutable equipment.

(Third Modification)
Next, a third modification will be described. In the third modification, the material and plate thickness of a part are taken into account when specifying a facility that can be substituted for the overcapacity facility.

  FIG. 20 is a diagram illustrating an example of the component information 201 in the third modification. The component information 201 in this modification includes a material 201g and a plate thickness 201h. The material 201g is information indicating the material of the component specified by the component ID. The plate thickness 201h is information indicating the thickness of the component.

  FIG. 21 is a diagram illustrating an example of the facility replacement information 203 in the third modified example. The equipment replacement information 203 in this modification includes a material condition 203e and a plate thickness condition 203f. The material condition 203e is information indicating the material of a part or material that can be manufactured in the post-change equipment. The plate thickness condition 203f is information indicating the thickness of a part or material that can be manufactured in the post-change equipment. The plate thickness condition 203f is, for example, the upper limit of the thickness of parts that can be manufactured.

  FIG. 22 is a flowchart showing the flow of an alternative assignment process in the third modification. The processing performed from step S241 to step S243 is the same as that in the above-described embodiment. First, the facility substitution allocation unit 115 identifies one of the overcapacity facilities (step S241). Next, the facility load movement man-hour ratio calculation unit 114 identifies a replaceable facility and a unit CAM creation man-hour for the specified overcapacity facility (step S243).

  Next, the equipment load movement man-hour ratio calculation unit 114 refers to the part information 201 for the parts allocated to the overcapacity equipment, and identifies the corresponding material and plate thickness (step S2451). Specifically, the equipment load movement man-hour ratio calculation unit 114 refers to the part information 201 using the information specified in step S22 and specifies the part assigned to the overcapacity equipment, and the corresponding material 201g and The plate thickness 201h is specified and stored in the memory unit 120.

  Next, the equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio with the changed equipment that can be substituted for the parts allocated to the overcapacity equipment (step S2452). As described above, the equipment load movement man-hour ratio is an index calculated for each combination of equipment scheduled to be manufactured, substitutable equipment, and parts assigned to the equipment scheduled to be manufactured. The equipment load movement man-hour ratio calculation unit 114 refers to the equipment replacement information 203 for the replaceable equipment extracted in step S243, and is stored in the memory section in step S2451 with the material conditions 203e and plate thickness conditions 203f of the replaceable equipment. Compare the material and thickness. The equipment load movement man-hour ratio calculation unit 114 identifies replaceable equipment that satisfies the conditions of material and plate thickness, and for each part assigned to the overcapacity equipment, manufacturing is assigned to each of the specified replaceable equipment. Calculate the equipment load movement man-hour ratio in the case of

  The processing performed from step S247 to step S261 is the same as that in the above-described embodiment. The equipment load movement man-hour ratio calculation unit 114 determines whether m = n (step S247). If the equipment load movement man-hour ratio calculation unit 114 does not determine that m = n (“NO” in step S247), the equipment load movement man-hour ratio calculation unit 114 increments m (step S249). When the equipment load movement man-hour ratio calculation unit 114 determines that m = n (in the case of “YES” in step S247), the equipment replacement assignment unit 115 determines that the equipment load movement man-hour ratio has the smallest equipment load movement man-hour ratio. -A combination of substitutable facilities is extracted, and a substitutive candidate facility and an alternative candidate part are specified (step S251). Next, the equipment replacement allocation unit 115 calculates the equipment load of the replacement candidate equipment (step S253). Next, the equipment replacement allocation unit 115 determines whether or not the equipment load of the replacement candidate equipment is within the processing capacity (step S225). If the equipment replacement allocation unit 115 determines that the equipment load of the replacement candidate equipment is within the processing capacity (“YES” in step S225), the equipment replacement allocation unit 115 changes the production plan information 202 (step S225). S257). Next, the facility substitution allocation unit 115 generates CAM creation instruction information 106 (step S259). The equipment replacement allocating unit 115 thereafter ends the process of this flowchart. If the equipment replacement assignment unit 115 does not determine that the equipment load of the replacement candidate equipment is within the processing capacity (“NO” in step S225), the equipment replacement assignment unit 115 has the next smallest equipment load movement man-hour ratio. A combination of parts, overcapacity equipment and substitutable equipment is extracted, and alternative candidate equipment and alternative candidate parts are identified (step S261).

  Thereby, the allocation to the alternative equipment can be performed in consideration of the manufacturing conditions of the equipment regarding the parts.

(Fourth modification)
Next, a fourth modification will be described. In the fourth modified example, for example, before the processing according to the present embodiment is started, the facility allocation execution screen 220 accepts selection of facilities for fixing the allocation of manufacturing. The equipment replacement allocation unit 115 treats the selected equipment as not replaceable when specifying a replaceable equipment for the overcapable equipment (step S243 described above). As a result, it is possible to select not to replace any equipment. For example, when it is not desired to apply a load to a predetermined equipment, the input of the equipment to fix the allocation is accepted. Flexibility to take into account needs for decisions.

(Second Embodiment)
Next, a second embodiment will be described. In the second embodiment, when determining an alternative facility, the similarity of tools when the facility manufactures a part is considered. Hereinafter, a different point from 1st Embodiment is demonstrated and description is abbreviate | omitted about the overlapping point.

  FIG. 23 is a diagram illustrating an example of functional blocks of the component equipment assignment apparatus 10 according to the second embodiment. The arithmetic processing unit 110 further includes a unit CAM creation man-hour calculating unit 117. The storage unit 200 further includes CAM information 210 and tool information 211 in addition to the information described above.

  The unit CAM creation man-hour calculation unit 117 calculates a unit CAM creation man-hour based on the CAM information 210 and the tool information 211. The CAM information 210 is information for managing tools and the like used when manufacturing parts for each facility. The tool information 211 is information for managing tools owned by each facility.

  FIG. 24 is a diagram illustrating an example of the CAM information 210. In the CAM information 210, a tool 210c necessary for manufacturing is associated with a combination of the component ID 210a and the equipment 210b.

  The component ID 210 is identification information for identifying a component, and corresponds to the component ID 201 a of the component information 201. The facility 210b is information for identifying the facility, and corresponds to the facility 201d of the component information 201.

  The tool 210c is information for specifying a tool used when the component ID 210a is manufactured by the equipment 210b. The tool 210c is a tool that the associated equipment 210b has.

  Note that the CAM information 210 illustrated in FIG. 24 includes a tool 210c having “tool a”, “tool b”, and a tool whose tool ID 210b is “equipment A” in order to manufacture a component having a component ID 210a “P01”. It indicates that the tools “tool c” and “tool d” are used. Similarly, in order to manufacture the same part whose part ID 210a is “P01” in the equipment whose equipment 210b is “equipment B”, the tool 210c is “tool a”, “tool b”, “tool c”, It shows that the tool “tool e” is used.

  FIG. 25 is a diagram illustrating an example of the tool information 211. The tool information 211 is information that associates the equipment 211a with the tool 211b that the equipment has.

  The equipment 211a is information for specifying the equipment and corresponds to the equipment 201d of the part information 201. The tool 211b is a tool that the equipment 211a has. For example, the tool information 211 illustrated in FIG. 25 indicates that the equipment whose equipment 211a is “equipment A” has the tool 211b having “tool a”, “tool b”, “tool c”, and “tool d”. ing.

  FIG. 26 is a flowchart illustrating the flow of an alternative assignment process in the second embodiment. The process performed in step S241 is the same as the process in the first embodiment. First, the facility substitution allocating unit 115 identifies one facility among the overcapacity facilities (step S241).

  Next, the facility load movement man-hour ratio calculation unit 114 refers to the facility replacement information 203 and extracts a replaceable facility for the facility specified in Step S241 (Step S242). Specifically, the equipment load movement man-hour ratio calculating unit 114 extracts the equipment ID 203a corresponding to the specified equipment and the post-change equipment 203b of the record whose substitution possibility 203c is “possible”.

  Next, the unit CAM creation man-hour calculation unit 117 calculates the unit CAM creation man-hour between the specified overcapacity facility and the replaceable facility (step S244). The unit CAM creation man-hour calculation unit 117 uses the CAM information 210 and the tool information 211 to calculate a unit CAM creation man-hour for each part allocated to the overcapacity equipment specified in step S241.

  The following (Equation 2) is an equation for calculating the unit CAM creation man-hours.

M ′ _{i, j, k} is a unit CAM creation man-hour for the part i, the equipment j before change, and the equipment k after change. X _{i, j, k} is a tool matching ratio, which is an index indicating the commonality between the tool used in the pre-change equipment i and the tool used in the post-change equipment k in order to manufacture the part i. The tool matching ratio is calculated by, for example, (the number of tools that match the pre-change equipment and the post-change equipment / the number of tools used in the pre-change equipment).

The variable a is a man-hour that is proportional to (1−X _{i, j, k} ) which is a tool non-conformity rate between facilities. The variable a is, for example, the CAM data creation time per number of shape elements. The variable b is a man-hour that is regularly generated when the CAM data is replaced with the replacement of the equipment. The variable b is, for example, the time associated with data transfer. Note that the values of the variables a and b are predetermined by statistical values of past CAM creation times.

  In the above-described embodiment, calculation of the unit CAM creation man-hour when the production of the part “P01” is replaced from “equipment A” to “equipment B” will be described. First, the unit CAM creation man-hour calculation unit 117 refers to the CAM information 210, and "tool a" and "tool b" which are tools 210c when the "equipment A" as the pre-change equipment manufactures the part "P01". , “Tool c”, and “tool d”. Further, the unit CAM creation man-hour calculation unit 117 refers to the CAM information 210, and “tool a” and “tool b” which are the tools 210c when the “equipment B” which is the modified equipment manufactures the part “P01”. , “Tool c” and “tool e” are specified. The tool matching ratio is 75% (3/4 × 100).

Assuming that a = 12, b = 3, M ′ _{1, A, B} = 6 is calculated.

  Next, the equipment load movement man-hour ratio calculation unit 114 calculates the equipment load movement man-hour ratio using the unit CAM creation man-hour calculated in step S244. The following (Equation 3) is used for the calculation.

The difference from the above-described embodiment is that instead of unit CAM creation man-hours M _{j, k} that are fixed values for each combination of equipment before change, equipment after change, and parts, CAM information 210, tool information 211, and The point is that M ′ _{i, j, k} which is a unit CAM creation man-hour calculated based on parameters derived from the time used for the past CAM data creation time or the like is used.

  The processes after step S247 are the same as those in the above-described embodiment. The equipment load movement man-hour ratio calculation unit 114 determines whether m = n (step S247). If the equipment load movement man-hour ratio calculation unit 114 does not determine that m = n (“NO” in step S247), the equipment load movement man-hour ratio calculation unit 114 increments m (step S249). When the equipment load movement man-hour ratio calculation unit 114 determines that m = n (in the case of “YES” in step S247), the equipment replacement assignment unit 115 determines that the equipment load movement man-hour ratio has the smallest equipment load movement man-hour ratio. -A combination of substitutable facilities is extracted, and a substitutive candidate facility and an alternative candidate part are specified (step S251). Next, the equipment replacement allocation unit 115 calculates the equipment load of the replacement candidate equipment (step S253). Next, the equipment replacement allocation unit 115 determines whether or not the equipment load of the replacement candidate equipment is within the processing capacity (step S255). If the equipment replacement allocation unit 115 determines that the equipment load of the replacement candidate equipment is within the processing capacity (“YES” in step S255), the equipment replacement allocation unit 115 changes the production plan information 202 (step S202). S257). Next, the facility substitution allocation unit 115 generates CAM creation instruction information 106 (step S259). The equipment replacement allocating unit 115 thereafter ends the process of this flowchart. If the equipment replacement allocation unit 115 does not determine that the equipment load of the replacement candidate equipment is within the processing capacity (“NO” in step S255), the equipment replacement allocation unit 115 has the next smallest equipment load movement man-hour ratio. A combination of parts, overcapacity equipment and substitutable equipment is extracted, and alternative candidate equipment and alternative candidate parts are identified (step S261).

  According to this modification, the unit CAM creation man-hours used for calculating the equipment movement man-hour ratio can be automatically generated based on the past CAM data creation time record and the tool characteristics for each equipment. For this reason, even if the CAM creation man-hour is different from the actual situation, the maintenance man-hour of the original data such as the equipment substitution information 203 can be reduced, and the substitution equipment based on the more accurate equipment load movement man-hour ratio It becomes possible to plan the production allocation to.
