Description

Area use planning system, area use planning method, and area use planning device

Technical Field

The present invention relates to an area use planning system, an area use planning method, and an area use planning device.

Background

For example, in the case of manufacturing a large product such as a control panel, a production plan for efficiently using the work area of a factory needs to be prepared.

For example, patent document 1 discloses "a construction planning support device for a plant that supports planning and creation of building construction or renovation construction of a plant including a plurality of components constructed in a building area, the device including: a database unit 2 that stores a plurality of actual results data 5 of construction performed in the past; an input unit 1 that inputs a type and a construction site of a construction object that is the same as or similar to a predetermined construction; an actual result data extracting means 11 for extracting actual result data of the past construction corresponding to the type and construction site of the construction target inputted by the input means 1 from the database means 2; and a plan creation unit 12 for creating a procedure plan table in which the work content and the time-series order of the work to be performed are set, using the actual results data extracted by the actual results data extraction unit 11.

A social infrastructure system product such as a control panel is generally configured by a plurality of devices, and is a single-order design product designed, manufactured, tested, and shipped in accordance with a customer order.

The plurality of devices constituting the control panel differ in production resources such as a manufacturing line, a test area, and equipment depending on the type thereof, and competition of production resources occurs between the respective processes in the constituent elements (various control panels and various units) of the ordered control panel.

In particular, in the case of a large-sized product such as a control panel, it is necessary to secure not only an occupied area of the product itself but also a space for arranging equipment (a test apparatus or the like) necessary for each process or performing work when performing manufacturing and testing, and it is important to make a production plan satisfying these restrictions in advance in order to effectively use the work area.

In addition, in the mounting and testing process of the control panel or the like, a large crane or the like is required depending on the product size and specification, and an operation within a range in which a special power supply can be secured may be required. When an actual process plan is prepared, it is necessary to determine whether or not operations such as actual mounting and testing can be performed by considering these constraints in time series. In addition, when a long-term free space is generated in production planning, it is also possible to obtain benefits by renting the space for a certain period of time as an external warehouse.

Patent document 1 describes the following method: the spatial condition of each bucket unit of the operation area in the factory is calculated, and a process planning table is created. However, in the conventional process planning method, since it is not possible to determine in time series the restriction items regarding the places and the time periods corresponding to the uses of the work areas, it is not possible to make a use plan for effectively using the free space in the plant as described above.

< example of configuration of a regional use planning system as an embodiment of the present invention >

Fig. 1 shows a configuration example of an area use planning system 10 as an embodiment of the present invention.

The area use planning system 10 includes an input/output unit 100, a storage unit 200, and a calculation unit 300.

The input/output unit 100 receives input information 210 necessary for planning use of the area and stores the input information in the storage unit 200. The input/output unit 100 displays an input screen 110 (fig. 10) for instructing the start of the area use planning process, an output screen 120 (fig. 32) for showing the result of the area use planning process, and the like on a display (not shown).

The input/output Unit 100 may be, for example, a personal computer or the like including a CPU (Central Processing Unit), a memory, an input device, a display, a communication I/F (interface), and the like.

The storage unit 200 stores input information 210 input from the input/output unit 100. The storage unit 200 stores the output information 220 generated by the arithmetic unit 300. The storage unit 200 supplies the input information 210 and the output information 220 to the operation unit 300 as appropriate.

The storage unit 200 can employ a memory such as a hard disk drive or an information processing apparatus including a memory.

The input information 210 includes production plan information 211, work area information 212, area occupancy information 213, area usage condition information 214, and device power usage area information 215.

The production plan information 211, the work area information 212, the area occupancy information 213, the area usage condition information 214, and the device power usage area information 215 will be described below by way of example.

Fig. 2 shows an example of the production plan information 211. The production plan information 211 is information for managing execution plans of processes for producing a product ordered by a customer, and is composed of items of a product code, a process, a start date, and an end date. Fig. 2 shows an example in which a product (hereinafter, also referred to as a product "P10") having a product code "P10" performs a "test" process in a period from a start date "6/1" to an end date "6/8", and performs a "factory" process in "6/9".

Next, fig. 3 shows an example of the work area information 212. The work area information 212 is information for managing the size of each work area in the factory, and is composed of each item of the work area, the vertical [ m ], and the horizontal [ m ]. In the example of fig. 3, for example, the size of the work area "E10" is "7 [ m ] in vertical width and" 10[ m ] in horizontal width ".

Next, fig. 4 shows an example of the area occupancy information 213. The area occupation information 213 is information for managing a predetermined range for implementation of each process of each product, and is composed of each item of a product code, a process, a work area, a start point (X, Y), and an end point (X, Y). In the example of fig. 4, for example, the "test" process of the product code "P10" is a plan performed within a rectangular range indicated by the start point (6, 3) and the end point (9, 7) in the work area "E10". Further, the starting point is the upper left vertex of the rectangular range, and the end point is the lower right vertex of the rectangular range.

In the present specification, the X direction is defined as the lateral direction, the Y direction is defined as the vertical direction, and the starting point (A, B) is a block having a lateral width of 1[ m ] from the top left of the rectangular work area to a-1 to a [ m ] in the right lateral direction and a vertical width of 1[ m ] from the top left of the work area to B-1 to B [ m ] in the vertical direction. Similarly, the end point (C, D) is a range having a lateral width of 1[ m ] from the top left vertex of the rectangular work area to C-1 to C [ m ] in the right lateral direction and a vertical width of 1[ m ] from the top left vertex of the work area to D-1 to D [ m ] in the vertical direction. Therefore, the rectangular range represented by the start point (A, B) and the end point (C, D) represents a range having a horizontal width of (C-A +1) [ m ] and a vertical width of (D-B +1) [ m ].

Next, fig. 5 shows an example of the area usage condition information 214. The area usage condition information 214 is information for managing restrictions on the size of a range, a period, equipment, power supply, and the like required when the work area is used for each application, and is composed of each item of application, required minimum vertical length [ m ], required minimum horizontal length [ m ], required minimum period (day), required equipment, required power supply, and partition necessity. In the case of fig. 5, the following is shown: for example, the minimum vertical width of the range used for the "mounting" use is "2 [ m ]" and the minimum horizontal width is "2 [ m ]", and at least "10 (days)" must be secured as the occupied period.

Next, fig. 6 shows an example of the device power use area information 215. The device power source use area information 215 is information for managing the range of devices and power sources that can be used in the plant in each work area, and is composed of items of a work area, a device power source name, a start point (X, Y), and an end point (X, Y). In the case of fig. 6, the following is shown: for example, a range in which "power source" of "400V" can be used in the work area "E10" is a rectangular range represented by a start point (4, 2) and an end point (9, 7).

Returning to fig. 1. The output information 220 is obtained as a result of an area use planning process described later, and includes area use planning information 221, area use layout information 222, and area usage rate information 223.

The area use plan information 221, the area use layout information 222, and the area use rate information 223 will be described below as examples.

Fig. 7 shows an example of the area use plan information 221. The area use plan information 221 is information for managing the use period and the usable area for each use area, and is composed of a work area, a use plan, a use, a start date, an end date, and a usable area [ m ]²]The items of (1) are combined. The following is shown in the example of fig. 7: in the usage pattern "ES 01" in the work area "E10", the period from the start date "6/1" to the end date "6/8" in the "installation" use can use "26 [ m²]"is used in the above range.

Next, fig. 8 shows an example of the area use layout information 222. The area use layout information 222 is information for managing a work area and a work period for each use in the use plan of each work area, and is composed of items of the work area, a use plan, a product, a use, an assignment flag, a start point (X, Y), an end point (X, Y), a start date, and an end date. The following is shown in the example of fig. 8: for example, in the usage pattern "ES 01" in the work area "E10", in the "trial" use, a rectangular range (row 1) of the start point (6, 3) and the end point (9, 7) can be secured in the period from the start date "6/1" to the end date "6/8". In addition, the following cases are shown: for example, in the usage scenario "ES 01" in the work area "E10", in the "install" usage, a rectangular range (row 3) of the start point (1, 1) and the end point (10, 2) can be secured for the period from the start date "6/1" to the end date "6/30".

Here, as in the product "P10", the product code beginning with "P" is stored in the product item in an area that has already been scheduled for use in the production plan information 211 and the like, and "1" is stored in the allocation flag item. On the other hand, in the product item, the product code beginning with "F" is stored as in the product "F01", and the assignment flag "0" is stored in a range in which the use, the place, and the time zone are not determined to be scheduled for use in each work area by the area use scheduling process described later.

Next, fig. 9 shows an example of the area usage information 223. The area usage rate information 223 is information for managing usage rates of each work area and period for each usage plan, and is composed of items of a work area, a usage plan, a start date, an end date, and an area usage rate. The following is shown in the example of fig. 9: for example, in the usage pattern "ES 01" in the work area "E10", the area usage rate in the period from the start date "6/1" to the end date "6/30" is "85.5%". Further, a method of calculating the area usage rate will be described later.

Returning to fig. 1. The arithmetic unit 300 can be, for example, a personal computer or a server including a CPU, a memory, an input device, a display, a communication I/F, and the like.

The arithmetic unit 300 acquires information (input information 210) necessary for the area use planning process from the input/output unit 100 and the storage unit 200, performs the process, and outputs output information 220 obtained as a result thereof to the storage unit 200. The arithmetic unit 300 corresponds to the area use planning device of the present invention.

The arithmetic unit 300 includes an arithmetic processing unit 320 and a storage unit 310. The arithmetic processing unit 320 performs arithmetic processing (area use planning processing). The storage unit 310 is a work area for arithmetic processing in the arithmetic processing unit 320. The storage unit 310 temporarily stores information acquired from the input/output unit 100 and the storage unit 200 and the result of the arithmetic processing performed by the arithmetic processing unit 320.

The arithmetic processing unit 320 includes functional blocks of a data acquisition unit 321, a planned production area extraction unit 322, a usable area determination unit 323, an overlap area determination unit 324, an area use plan generation unit 325, an area use rate calculation unit 326, and a display control unit 327.

The data acquisition unit 321 acquires the input information 210 required by the arithmetic processing unit 320 from the storage unit 200 based on the information of the planned time period and the planned condition of the area use input by the user using the input screen 110 (fig. 10) displayed on the input/output unit 100, and stores the acquired information in the storage unit 310.

The scheduled production area extracting section 322 extracts the work area and the time period that have been scheduled to be used by the production plan, based on the production plan information 211 and the area occupancy information 213.

The usable area determination unit 323 determines whether or not the free space of each work area in the work area information 212 is usable for each time slot and use, and assigns the use, time slot, and range to the free space.

The overlap area judgment section 324 makes an overlap judgment of the work range and period that have been scheduled to be used by the production plan and the range and period of free space allocation within the work area.

The area use plan generating unit 325 generates the area use plan information 221 (fig. 7) by connecting the allocation results of the areas that can be used for each work area in time series. The area use plan generator 325 generates the area use layout information 222 (fig. 8).

The area usage rate calculation unit 326 calculates the usage rate of each work area based on the allocated range and the free space of the time series in the area usage plan, and generates the area usage rate information 223 (fig. 9).

The display control unit 327 supplies the generated area use plan information 221, area use layout information 222, and area use rate information 223 to the storage unit 200, and stores them as the output information 220. The display control unit 327 also generates the output screen 120 (fig. 32) based on the area use plan information 221, the area use layout information 222, and the area use rate information 223, and outputs the output screen to the input/output unit 100.

The display control unit 327 can output at least one of the area use plan information 221, the area use layout information 222, the area use rate information 223, and the output screen 120 to an external device other than the input/output unit 100 and the storage unit 200.

< area usage planning processing of area usage planning System 10 >

Next, an example of the area use planning process of the area use planning system 10 will be described.

Fig. 10 shows an example of an input screen 110 on which the user can instruct the start of the area use planning process. The input screen 110 is displayed on the display of the input/output unit 100 in accordance with a predetermined operation by the user.

An area planning period setting field 111, an area planning condition setting field 112, a plan addition button 113, a line addition button 114, a line deletion button 115, and an execution button 116 are provided on the input screen 110.

In the area planning period setting column 111, the user can set a period to be a target of the area use planning. In the area planning condition setting field 112, the user can set conditions for area planning. Here, the conditions for planning the area can be set to a plurality of plans when a plan for use of the free space is made in the work area, a plurality of uses can be set for each plan, and priorities can be set for each use.

In the case of this figure, four usage plans "ES 01" to "ES 04" have been set in the area plan condition setting column 112. For example, a usage "installation" is set in the usage scenario "ES 01". For example, the usage plan "ES 02" has two purposes "test" and "install", the priority of the purpose "test" is set to the first, and the priority of the purpose "install" is set to the second.

The scenario addition button 113 is clicked by the user, and thereby the usage scenario can be added. The line addition button 114 can be clicked by the user to add an application to an arbitrary usage plan. The line delete button 115 is clicked by the user, thereby enabling the use to be deleted from any use scheme. The execution button 116 is clicked by the user, whereby the start of the area usage planning process can be instructed.

Hereinafter, a case where the area planning period and the area planning condition shown in fig. 10 are set will be described as an example.

Next, fig. 11 is a flowchart illustrating an example of the area use planning process. Fig. 12 is a flowchart illustrating step S3 of fig. 11 in detail. Fig. 13 is a flowchart illustrating step S5 of fig. 11 in detail.

For example, when the work area in the factory is narrow and the production planning needs to be performed again, or when the use method of the free space in the future work area needs to be studied, the area use planning process in fig. 11 is started when the user sets information necessary for the input screen 110 (fig. 10) and clicks the execution button 116.

Further, it is assumed that production plan information 211, work area information 212, area occupancy information 213, area usage condition information 214, and device power usage area information 215 shown in fig. 2 to 6 have been stored in the storage unit 200 as input information 210.

First, the data acquisition unit 321 of the arithmetic processing unit 320 acquires the input information 210 (the production plan information 211, the work area information 212, the area occupancy information 213, the area usage condition information 214, and the device power usage area information 215) corresponding to the area plan period ("6/1" to "6/30" in the present case) set on the input screen 110 from the storage unit 200 and stores the acquired information in the storage unit 310 (step S1).

Next, the planned production area extraction unit 322 extracts the work area and the time period that have been planned to be used in the production plan, from the production plan information 211 and the area occupancy information 213 in the storage unit 310, and stores the extracted work area and time period in the storage unit 310 (step S2).

Specifically, the planned production area extracting unit 322 extracts the product codes and the processes from the production plan information 211 (fig. 2) in the order of the start date from the morning to the evening, and extracts the work area occupied when the extracted product codes and processes are executed and the range thereof from the area occupancy information 213 (fig. 4). The planned production area extracting unit 322 groups the processes performed in the same work area on the same start date, adds a production event number to the grouped processes, generates production event information 3221 (fig. 14), and stores the production event information in the storage unit 310.

Fig. 14 shows an example of the production event information 3221 generated in step S2. In the present case, for example, the start date "6/1" of the "trial" process of the product "P10" and the "installation" process of the product "P11" are the same as the work area "E10", and therefore the same production event number "1" is attached. Since the "shipping" step is not stored in the area occupancy information 213 (fig. 4), and does not occupy the range of the work area, the "0" is recorded at the start point (X, Y) and the end point (X, Y) indicating the occupied range. The "shipment" process means that the product of the product "P10" disappears from the work area "E10".

Next, the usable area determination unit 323 pays attention to the area usage plan set on the input screen 110 in the order of the numbers, pays attention to the area usage plan in the order of the production event numbers, determines whether or not the free space of each work area of each production event in the work area information 212 (fig. 3) of the storage unit 310 is usable by time zone and use, and assigns use, time zone, and range to the work area (step S3).

The detailed processing of step S3 is explained with reference to fig. 12.

First, the usable area determination unit 323 specifies a work area corresponding to the production event number of interest from the production event information 3221 (fig. 14) stored in the storage unit 310, acquires the size of the work area from the work area information 212 (fig. 3), allocates the range of each process in the production event to the work area, generates the use allocation information 2221 (fig. 16), and stores the use allocation information in the storage unit 310 (step S31).

Specifically, the usable area determination unit 323 focuses on the production event number "1" and the work area thereof is "E10" in the production event information 3221, and thus obtains the vertical width "7 [ m ] and the horizontal width" 10[ m ] as the size of the work area "E10" from the work area information 212. Further, the usable area determining section 323 assigns a predetermined range of production for which use has been scheduled to the start date "6/1" in the work area "E10" to the work area "E10" in accordance with the production event information 3221 (fig. 14). Fig. 15 shows a state in which a predetermined range of production (a region of the "trial" process of the product "P10" and a range of the "installation" process of the product "P11") that has been scheduled for use is allocated to the work area "E10". The usable area determination unit 323 generates the usage assignment information 2221 (up to the 1 st and 2 nd rows in fig. 16) having the assignment result as data.

Next, the usable area determination unit 323 focuses on each application of the focused area usage plan with respect to the work area in priority based on the area usage condition information 214 (fig. 5) and the device power source usage area information 215 (fig. 6), searches for a start point of a free space (a rectangular range having an aspect ratio of 2[ m ] or more) (step S32), and determines whether or not the start point of the free space can be searched (step S33). Here, when the usable area determination unit 323 determines that the start point of the free space can be searched (step S33: "yes"), the process proceeds to step S34. Conversely, when the usable area determination unit 323 determines that the start point of the free space has not been searched (step S33: NO), the process proceeds to step S37.

Specifically, in the input screen 110 (fig. 10), the area usage plan "ES 01" of interest is set only for the "installation" purpose, and when referring to the area usage condition information 214 (fig. 5), since the device, the power supply, and the partition are not required for the "installation" purpose, the start point of the free space is sequentially searched in the Y direction and the X direction from the upper left origin (1, 1) of the work area "E01" without considering the position of the device and the power supply.

In the case of the work area "E10" shown in fig. 15, the origin (1, 1) is free, and therefore the usable area determination unit 323 determines the origin (1, 1) as the starting point of the free space.

Next, the area determination unit 323 searches for the end point of the maximum free space starting from the origin (1, 1) (step S34). In the case of the work area "E10" shown in fig. 15, (10, 2) is determined as the end point of the maximum free space starting from the point (1, 1). In this case, the size of the free space is 10 × 2[ m ].

Next, the usable area determination unit 323 determines whether or not the free space determined in steps S32 and S34 is usable for each application (step S35). Here, when the usable area determination unit 323 determines that it is usable, the process proceeds to step S36. On the other hand, when the usable area determination unit 323 determines that the usable area cannot be used, the process returns to step S32, and the process from step S32 onward is repeated for the next use.

In the present case, it is known from the area use condition information 214 (fig. 5) that the minimum size of the range required for the "installation" use is 2 × 2[ m ] and the free space is 10 × 2[ m ], and therefore the usable area determination unit 323 determines that the free space can be used for the "installation" use.

Next, the free space determined to be available by the available area determination unit 323 is assigned the usage, the range, and the start date, and the usage assignment information 2221 in the storage unit 310 is updated based on the result (step S36). Specifically, the data of line 3 of the usage assignment information 2221 shown in fig. 16 is added.

Further, the item of the allocation flag in the usage allocation information 2221 (fig. 16) stores "1" in the case where a specific product to be produced is decided. Conversely, "0" is stored when the product to be produced is not decided, that is, when the free space to which the use is allocated, and the product code beginning with "F" is stored as a default value in the product column.

Thereafter, the process returns to step S32, and step S32 and thereafter are repeated again, whereby a search and allocation of free space are further performed in the work area "E01", and the 4 th and 5 th lines of the usage allocation information 2221 shown in fig. 16 are added.

Fig. 17 shows the state of allocation of the range in the work area "E10" corresponding to the 1 st to 5 th rows of the usage allocation information 2221 shown in fig. 16. That is, the figure shows a state in which the work area "E10" is assigned with the range of the "test" process of the product code "P10" as the production scheduled range that has been scheduled to be used, the range of the "mount" process of the product code "P11", the range of the "mount" process of the product code "F01" as the area in which the use reservation has not been made, the range of the "mount" process of the product code "F02", and the range of the "mount" process of the product code "F03". In addition, the rectangular ranges of the start points (10, 3) and the end points (10, 7) shown in the figure do not satisfy 2[ m ] in lateral width and are not detected as empty spaces, and therefore cannot be assigned to any use.

Then, the usable area determination unit 323 determines whether or not the use of the currently focused area usage plan remains the use that is not focused (step S37). If it is determined that there is an application that is not focused on (yes in step S37), the process returns to step S32, and step S32 and thereafter are repeated focusing on the application with the second highest priority. If it is determined that the use that is not focused is not left (no in step S37), the usable area determination unit 323 ends the detailed process of step S3.

In the present case, only the "install" use is set in the area usage plan "ES 01", and other uses do not exist, so the usable area determination unit 323 ends the detailed processing of step S3 of the area usage plan "ES 01". Then, the process advances to step S4 of fig. 11.

Next, the usable area determination unit 323 determines whether or not there is a production event that has not been paid attention to in step S3 (step S4), and if the usable area determination unit 323 determines that there is a production event that has not been paid attention to (step S4: "yes"), the process proceeds to step S5. Conversely, when the usable area determination section 323 determines that no production event remains that is not of interest (step S4: NO), the processing proceeds to step S6.

In the present case, as is known from the production event information 3221 (fig. 14), the production event numbers in the area planning period ("6/1" to "6/30") exist in "1" to "5", and no attention is paid to the production event number "2" and thereafter, so the process proceeds to step S5.

Next, the overlap area determination unit 324 performs overlap determination of the range and the period to which the free space has been allocated as the area usage plan for the next work range and period scheduled to be used, and updates the usage allocation information 2221 (fig. 16) based on the result of the overlap determination (step S5).

The detailed processing of step S5 is explained with reference to fig. 13.

First, the overlapping area judging section 324 acquires the production event information 3221 (fig. 14) and the usage assignment information 2221 (fig. 16) from the storage section 310 (step S51). In the present case, data of the production event number "2" of the production event information 3221 is focused on. This data indicates that the start date of the "install" process for product "P12" is "6/4". When the data of the previous production event number "1" is noted, the end dates of the "test" step and the "installation" step are "6/8", and thus it is understood that at the time point of "6/4", as shown in fig. 18, the products "P10" and "P11" corresponding to the production event number "1" are also present in the work area "E10".

Therefore, the overlap area determination unit 324 adds and updates the data in row 6 in correspondence with the data of the production event number "2" to the acquired usage assignment information 2221 (fig. 16), thereby generating usage assignment information 2222 (fig. 19) and storing it in the storage unit 310.

Fig. 19 shows the updated usage allocation information 2222. The data in row 6 of the usage allocation information 2222 indicates that the "installation" process of the product "P12" occupies ranges of the period from the start date "6/4" to the end date "6/13", the start point (1, 5), and the end point (4, 6).

Next, the overlapping area determination unit 324 refers to the usage allocation information 2222 (fig. 19), compares the area (data of the allocation flag "1") that has been scheduled to be used with the allocation result of the free space (data of the allocation flag "0"), and determines whether or not there is an overlapping area (step S52). Here, when the overlapping area determination unit 324 determines that there is an overlapping area (yes in step S52), the process proceeds to step S53. Conversely, when the overlapping area determination unit 324 determines that there is no overlapping area (step S52: NO), the detailed processing of step S5 is terminated.

In the present case, the overlapping judgment in step S52 is essentially to compare the state of the work area "E10" shown in fig. 17 with the state of the work area "E10" shown in fig. 18. As can be seen from comparison of fig. 17 and 18, the range of the "mounting" process of product "F02" overlaps the range of the "mounting" process of product "P12", and therefore the process proceeds to step S53.

Next, the overlap area determination unit 324 sets the date to the end date of the blank field so that the allocation result of the free space (data of the allocation flag "0") of the overlapped usage allocation information 2222 (fig. 19) does not overlap. In the present case, since the overlap occurs after "6/4", the day "6/3" before the overlap day is set in the end date of the 3 rd line of the usage assignment information 2222.

Next, the overlap area determination unit 324 determines whether or not the free space with the end date set therein satisfies the required minimum time period for each application (step S54). Here, when the overlap area judgment section 324 judges that the required minimum period is satisfied (step S54: yes), the detailed processing of this step S5 is ended. Conversely, when the overlap area judgment section 324 judges that the required minimum period is not satisfied (step S54: NO), the allocation result of the free space which does not satisfy the required minimum period is deleted (step S55).

In the present case, the "installation" step of the product code "F02" of the end date is set, and the required minimum time period is "10 (days)" from the area use condition information 214 (fig. 5). On the other hand, the "install" process for the product code "F02" can allocate only 3 days from the start date "6/1" to the end date "6/3" and does not satisfy the required minimum period, and therefore the data relating to the product code "F02" on the 3 rd row is deleted from the usage allocation information 2222 (fig. 19).

In the above, the detailed processing of step S5 corresponding to the production event number "2" is ended. Then, the process returns to step S3 of fig. 11.

Next, by repeating steps S3 to S5, the overlapping area determination unit 324 sequentially focuses on the production event numbers "3" to "5" in the production event information 3221 (fig. 14) and executes the detailed processing of step S5. As a result, the assignment state in the work area "E10" changes as shown in fig. 20. The usage allocation information 2222 (fig. 19) is also updated by the overlapping area determination unit 324, and data (the 1 st to 10 th line data in fig. 8) corresponding to the usage pattern "ES 01" in the area usage layout information 222 (fig. 8) is generated and stored in the storage unit 310.

For example, in the state corresponding to the production event number "3" in fig. 20, the ranges of the start points (5, 5) and the end points (10, 7) are temporarily allocated to the "installation" use of the product "F05", but overlap with the range of the "trial" process of the product "P12" in the next production event number "4", and do not satisfy the required minimum period, and therefore, the data corresponding thereto are deleted from the area use layout information 222 (fig. 8).

Thereafter, since the start date of the production event number "6" of the production event information 3221 (fig. 14) is after the area planning period, the usable area determination part 323 determines that no production event remains which has not been paid attention to in step S3 (step S4: no), and the processing proceeds to step S6.

Next, the usable area determination unit 323 determines whether or not an area usage plan that is not focused remains in all the area planning conditions set on the input screen 110 (step S6). If the usable area determination unit 323 determines that an area usage plan that is not focused on remains (yes in step S6), the process returns to step S3.

In the present case, since the region of interest usage scenario "ES 01" remains without the region of interest usage scenarios "ES 02" to "ES 04", the region determination unit 323 may then perform steps S3 to S6 while focusing on the region usage scenario "ES 02".

In the case of the area usage plan "ES 02", the priority of the "test" use and the "installation" use is set on the input screen 110 (fig. 10). The detailed processing of step S3 in the case of the region of interest usage scenario "ES 02" is described with reference to the flowchart of fig. 12.

First, the usable area determination section 323 specifies the work area "E10" corresponding to the production event number "1" of interest from the production event information 3221 (fig. 14), and acquires the size (10 × 7[ m ]) of the work area "E10" from the work area information 212. Then, the usable area judging section 323 assigns a predetermined range of production for which use has been scheduled to the start date "6/1" in the work area "E10" to the work area "E10" in accordance with the production event information 3221 (fig. 14) (step S31).

Next, the usable area determination unit 323 focuses on each use of the focused area usage plan in priority with respect to the work area based on the area usage condition information 214 (fig. 5) and the device power source usage area information 215 (fig. 6), and searches for a start point of a free space (step S32).

Specifically, in the case of the area usage plan "ES 02", the area usage plan is prepared in the order of "test" use and "installation" use, but the "400V" power supply is required for "test" use based on the area usage condition information 214 (fig. 5). Therefore, the usable area determination unit 323 refers to the device power source use area information 215 (fig. 6), identifies a range of the start point (4, 2) and the end point (9, 7) in which the "400V" power source can be used in the work area "E10", and allocates only the free space for the "test" use to the range. Fig. 21 shows the state of the work area "E10" at this point in time, and the range that can be used for the "test" application, that is, the range that can use the "400V" power supply is within the thick-framed broken line, and therefore the start point (4, 2) of this range is determined as the start point of the free space for the "test" application (step S33: yes). Then, the end points (5, 7) that can secure the maximum free space for the start points (4, 2) of the free space are searched and determined (steps S33, S34).

Next, the usable area determination unit 323 refers to the area use condition information 214 (fig. 5), compares the minimum size (2 × 2[ m ]) required for the "test" use with the size (2 × 6[ m ]) of the free space, and determines that the free space can be used for the "test" use (step S35: yes). Next, as shown in fig. 22, the usable area determination unit 323 allocates the use purpose "test", the range of the start point (4, 2), the end point (5, 7), and the start date "6/1" to the free space determined to be usable, generates use purpose allocation information (not shown), and stores the use purpose allocation information in the storage unit 310.

Thereafter, the process returns to step S32, and steps S32 to S36 are repeated, but since there is no more free space available for the use of the "test" application, the process proceeds to step S37, and the usable area determination unit 323 determines whether or not the use of the focused area usage scenario "ES 02" remains the use of no focus (step S37). In the present case, since the "mounting" purpose that is not focused on remains (step S37: "yes"), the process returns to step S32, and repeats step S32 after focusing on the "mounting" purpose, thereby adding the allocation of the range of the "mounting" purpose of product "F02", the range of the "mounting" purpose of product "F03", and the range of the "mounting" purpose of product "F04" to the state of work area "E01" shown in fig. 22, and fig. 23 shows the allocation state of work area "E01". Then, the usage assignment information 2223 shown in fig. 24 is generated and stored in the storage unit 310. Then, the process advances to step S4 of fig. 11.

Then, the usable area determination section 323 determines that an unattended production event remains in step S3 (step S4: YES), and the processing returns to step S3 via step S5.

Thereafter, the usable area determination unit 323 sequentially focuses on the production event numbers "2" to "5", and repeats steps S3 to S5. As a result, the assignment state to the work area "E10" changes as shown in fig. 25. The usage allocation information 2223 (fig. 24) is also updated by the overlap area determination unit 324, and data (data on the 11 th to 22 th rows) corresponding to the usage pattern "ES 02" of the area usage layout information 222 (fig. 8) is generated and stored in the storage unit 310.

Thereafter, the usable area determination section 323 determines that no unattended production event remains in step S3 (step S4: NO), and the process proceeds to step S6.

Subsequently, the usable area determination unit 323 determines that an area usage scenario not to be focused on remains (step S6: YES), and the process returns to step S3.

In the present case, since the region usage plan "ES 02" remains with the region usage plans "ES 03" and "ES 04", the usable region determination unit 323 sequentially focuses on the region usage plans "ES 03" and "ES 04" next, and executes steps S3 to S6.

As a result of the usable region determination unit 323 performing steps S3 to S6 focusing on the region use plan "ES 03", the assignment state to the work region "E10" changes as shown in fig. 26. The usage allocation information 2223 (fig. 24) is also updated by the overlapping area determination unit 324, and data (data on the 1 st to 12 th rows) corresponding to the usage pattern "ES 03" of the area usage layout information 225 shown in fig. 28 is generated.

Next, as a result of the step S3 to step S6 being executed with the region determination unit 323 focusing on the region use plan "ES 04", the assignment state to the work region "E10" changes as shown in fig. 27. Then, the usage allocation information 2223 (fig. 24) is also updated by the overlapping area determination unit 324, and data (data on the 13 th to 23 th rows) corresponding to the usage pattern "ES 04" of the area usage layout information 225 shown in fig. 28 is generated.

Next, the area use plan generating unit 325 generates the area use plan information 221 (fig. 7) based on the area

use layout information

222 and 2225 generated thus far, and stores the area use plan information in the storage unit 310 (step S7).

Specifically, in the present case, the area usage plan generating unit 325 acquires the area usage layout information 222 (fig. 8) corresponding to the area usage plans "ES 01" and "ES 02" and the area usage layout information 2225 (fig. 28) corresponding to the area usage plans "ES 03" and "ES 04" from the storage unit 310. Then, the area usage plan generating unit 325 extracts data with an allocation flag of "0" from the data of the area

usage layout information

222 and 2225, and calculates the size of the usable range from the start point and the end point of each data, thereby generating the area usage plan intermediate information 2211 shown in fig. 29.

Further, the area usage plan generating unit 325 generates the area usage plan information 221 (fig. 7) by adding the available ranges in time series for each work area, usage plan, and usage, by using the area usage plan intermediate information 2211 (fig. 29).

For example, in the use of "installation" of the work area "E10" and the area usage plan "ES 01" in the area usage plan intermediate information 2211 (fig. 29), the time periods of "6/1" to "6/8" can sum up the usable ranges of the products "F01" and "F03", and sum up the result "26 [ m [ m ] ]²]"is described in line 1 of the area use plan information 221 (fig. 7). In addition, in the use of "installation" of the work area "E10" and the area usage plan "ES 01", the time period from "6/9" to "6/13" can be counted up to the usable ranges of the products "F01", "F03", and "F04", and the result "30 [ m [" m "]²]"is described in the 2 nd line of the area use plan information 221 (fig. 7). In the "installation" use of the work area "E10" and the area usage plan "ES 01", 6/14 "to" 6/2The period of 0 "can sum up the usable ranges of the products" F01 "," F03 "," F04 "," F06 ", the result" 45[ m²]"is described in the 3 rd line of the area use plan information 221 (fig. 7). In addition, in the use of "installation" of the work area "E10" and the area usage plan "ES 01", the time period from "6/21" to "6/30" can be counted up to the usable ranges of the products "F01", "F03", "F04", "F06", and "F07", and the result "55 [ m" is counted up²]"is described in the 4 th line of the area use plan information 221 (fig. 7).

Next, the area usage rate calculator 326 calculates the time-series area usage area for each work area based on the area usage plan information 221 (fig. 7) and the area usage layout information 222 (fig. 8) and 2225 (fig. 28) generated in step S7, and generates the area usage rate information 223 (fig. 9) based on the work area information 212 (fig. 3) and stores the same in the storage unit 310 (step S8).

Specifically, in the present case, the area usage plan generating unit 325 extracts data with the allocation flag "1" from the data of the area

usage layout information

222 or 2225, and calculates the size of the usable range from the start point and the end point of each data, thereby generating the area usage plan intermediate information 2212 shown in fig. 30. In this case, only one data is left and the other data is deleted, with the same work area, product, use, start date, and end date and with different use schemes.

The area usage plan generating unit 325 calculates the area usage area for each time series of area usage plans based on the area usage plan intermediate information 2212 (fig. 30) and the area usage plan information 221 (fig. 7), and generates the area usage rate intermediate information 2231 (fig. 31).

For example, as for the area usage plan "ES 01", the usable range of "6/1" to "6/3" is "24 (═ 20+4) [ m ] as can be seen from the area usage plan intermediate information 2212 (fig. 30)²]"from the area use plan information 221 (fig. 7)," 6/1 "to" 6/3 "are available in the range of" 26[ m²]", so the total value is" 56[ m ]²]"is described in line 1 of the area usage rate intermediate information 2231 (fig. 31). In additionIn addition, as can be seen from the area use plan intermediate information 2212 (fig. 30), the usable range of "6/4" to "6/8" is "32 (═ 20+4+8) [ m²]"from the area use plan information 221 (fig. 7)," 6/4 "to" 6/8 "are available in the range of" 26[ m²]", and thus the total value" 58[ m ]²]"is described in line 2 of the area usage intermediate information 2231 (fig. 31). As can be seen from the area use plan intermediate information 2212 (fig. 30), the usable range of "6/9" to "6/13" is "16 (═ 8+8) [ m²]"from the area use plan information 221 (fig. 7)," 6/9 "to" 6/13 "are available in the range of" 30[ m²]", and thus the total value is" 46[ m ]²]"is described in line 3 of the area usage rate intermediate information 2231 (fig. 31).

The area usage plan generating unit 325 also sums the area usage area of the area usage rate intermediate information 2231 (fig. 31) for each area usage plan, and divides the area by the area of the work area "E10" (70[ m) known from the work area information 212 (fig. 3)²]) The area use rate information 223 (fig. 9) is generated by multiplying the area planning period (30 days (6/1-6/30)).

For example, for the area usage pattern "ES 01", when the area usage area of the area usage pattern "ES 01" is summed in the area usage rate intermediate information 2231 (fig. 31), 1795(═ 50 × 3+58 × 5+46 × 5+65 × 7+67 × 10) [ m × 10 ]²]When divided by 2100(═ 70 × 30) [ m²]The time becomes 0.855.

For example, for the area usage plan "ES 02", when the area usage area of the area usage plan "ES 02" is summed in the area usage middle information 2231 (fig. 31), 1719(═ 46 × 3+54 × 5+44 × 5+63 × 7+65 × 10) [ m ″)²]When divided by 2100(═ 70 × 30) [ m²]The average molecular weight becomes 0.819.

Finally, the display control unit 327 outputs the area use plan information 221 (fig. 7), the area use layout information 222 (fig. 8), and the area use rate information 223 (fig. 9) stored in the storage unit 310 to the storage unit 200 and stores them as the output information 220. Then, the display control unit 327 generates the output screen 120 (fig. 32) based on the area use plan information 221, the area use layout information 222, and the area use rate information 223, outputs the output screen to the input/output unit 100, and displays the output screen on the display of the input/output unit 100 (step S9). The area usage planning process is ended, as described above.

Next, fig. 32 shows a display example of the output screen 120. A planned-period display column 121, an area-use planned display column 122, an area-use-ratio display column 123, and an area-use layout display column 124 are provided on the output screen 120.

The area planning period input to the input screen 110 by the user is displayed in the planning period display field 121. A schedule table showing a work area, a usage plan, a plan for each use, and an area of a usable area in each period based on the area usage plan information 221 (fig. 7) is displayed in the area usage plan display field 122. Thus, the user can grasp the period of each usage pattern and the area of the usable region for each application, and can study the usage pattern such as the region shortage for each process.

The area usage rate for each usage pattern based on the area usage rate information 223 (fig. 9) is displayed in the area usage rate display field 123. Thus, the user can grasp the area usage rate for each usage pattern, and can study the usage pattern of the effective usage area.

The use layout of the work area based on the area use layout information 222 (fig. 8) is displayed in the area use layout display field 124. Further, in the area usage layout display field 124, the user can select or input a work area, a usage plan, and a date in which the usage layout is to be displayed. In addition, the user can select an application and can highlight the range allocated to the selected application.

In the case of this drawing, the use layout corresponding to the work area "E01", the use pattern "ES 02", and the date "6/21" is displayed in the area use layout display field 124, and the range of the use of "test" is highlighted. Thus, the user can specify a specific execution policy for the area shortage and the like.

< summary >

According to the area use planning process described above, in a factory that produces large products requiring a work area to be secured, an area use plan for each application, such as actual manufacturing, testing, and rental of areas, can be prepared for vacant space that will occur in time series in the future. As a result, even in a situation where the work area is a bottleneck in production planning, efficient production of products can be planned and executed efficiently, and thus the production cycle can be shortened. Further, since the feasibility of external rental or the like of a work area in the future can be confirmed without affecting the production plan in the plant, the work area in the plant can be effectively used.

The area usage planning system 10 shown in fig. 1 realizes the input/output unit 100, the storage unit 200, and the calculation unit 300 by different devices, but the input/output unit 100, the storage unit 200, and the calculation unit 300 may be realized by one device (for example, a personal computer).

Fig. 33 is a block diagram showing an example of a hardware configuration of a computer that functions as the area usage planning system 10 by executing a program.

In the computer 1000, a CPU1001, a ROM (Read Only Memory) 1002, and a RAM (Random Access Memory) 1003 are connected to each other via a bus 1004. The RAM 1003 can function as the storage unit 310 of the arithmetic unit 300.

An input/output interface 1005 is also connected to the bus 1004. The input/output interface 1005 is connected to an input unit 1006, an output unit 1007, a storage unit 1008, a communication unit 1009, and a driver 1010.

The input unit 1006 is constituted by a keyboard, a mouse, a microphone, and the like. The output unit 1007 is configured by a display, a speaker, and the like. The input unit 1006 and the output unit 1007 can function as the input/output unit 100.

The storage unit 1008 is configured by a hard disk, a nonvolatile memory, and the like. The storage unit 1008 can function as the storage unit 310 of the storage unit 200 or the arithmetic unit 300. The communication unit 1009 is configured by a network interface or the like. The drive 1010 drives a removable medium 1011 such as a magnetic disk, an optical magnetic disk, or a semiconductor memory. The removable medium 1011 can function as the storage unit 310 of the storage unit 200 or the arithmetic unit 300.

In the computer 1000 configured as described above, the CPU1001 realizes the arithmetic processing unit 320 of the arithmetic unit 300 by loading and executing a program stored in the storage unit 1008 to the RAM 1003 via the input/output interface 1005 and the bus 1004, for example.

The program executed by the computer 1000(CPU1001) can be provided by being recorded on a removable medium 1011 such as a cartridge medium. In addition, the program can be provided via a wired or wireless transmission medium such as a local area network, the internet, digital satellite broadcasting, or the like.

In the computer 1000, by mounting the removable medium 1011 to the drive 1010, a program can be installed in the storage unit 1008 via the input/output interface 1005. The program is received by the communication unit 1009 via a wired or wireless transmission medium, and can be installed in the storage unit 1008. The program can be installed in advance in the ROM 1002 or the storage unit 1008.

The program executed by the computer 1000 may be a program that performs processing in time series in the order described in the present specification, or may be a program that performs processing in parallel or at a desired timing such as when calling.
