Description

  The present invention relates to a production scheduling technique when processing is performed in parallel by a plurality of facilities, and more particularly, to a technique that performs scheduling with high production efficiency in the case of including a process of performing continuous production.

  A production plan for producing a plurality of types of products by a plurality of processes is required to maximize productivity as well as to meet the delivery date. An example of such a production line composed of a plurality of processes is a production line of a metal material factory such as steel, copper plate, aluminum plate.

  In such a production line, a technique for creating a schedule for keeping the delivery date and increasing the production efficiency has been proposed.

  For example, in a series of steelmaking processes, when performing so-called post-scheduling scheduling for every charge corresponding to one cup of molten steel, so-called post-scheduling scheduling, there is equipment competition due to multiple charges in the same equipment With regard to the plurality of charges, a technique has been proposed in which equipment competition is resolved by advancing the time of use in each upstream process equipment, and a practical steelmaking schedule without equipment competition is obtained (see Patent Document 1). .

  Here, the competition that must be taken into consideration when creating the production schedule is not limited to the equipment.

  Generally, when processing is performed in equipment such as a factory, a person who operates the equipment, that is, a so-called operator is arranged for each equipment. When the difficulty level of the operation at the facility is higher than the skill level of the operator arranged in the facility, the supervisor instructs the operator. The supervisor means an operator who has a high experience value for operation and a relatively high skill level. In this way, the supervisor (skilled person) guides the operator (non-skilled person) who performs processing that is more difficult than his skill level, thereby shortening the processing time and improving productivity. , Preventing quality degradation.

  However, in recent years, due to the fact that the baby boomers have reached retirement age, the number of skilled persons who can become supervisors has decreased. Therefore, in the production line as described above, as shown in FIG. 1, there is a case where one supervisor has to give guidance to a plurality of operators. In other words, non-experts compete.

  When one supervisor gives guidance to a large number of operators, there is a possibility that the supervisor may not be able to provide sufficient guidance, and there may be a problem that productivity and quality deteriorate.

  Therefore, it is desirable to create a production schedule that minimizes the number of operators that one supervisor must give guidance.

  Here, among the plurality of processes, there is a process where it is desirable to perform continuous production. Continuous production means that when products are sequentially processed in a certain process, the next product to be processed is connected to the preceding product in some way on the entry side of the equipment in that process. This is a production system in which products are manufactured and processed without interruption. In addition, in continuous production, not only when the preceding product and the product to be processed next are physically connected and processed, but they are not physically connected but are processed intermittently. Cases are also included. Continuous production is performed, for example, at a metal material production site using casting equipment, rolling equipment, annealing equipment, plating equipment, and the like.

  In such a continuous production process, the processing difficulty is usually higher when different products are processed successively than when similar products are processed continuously.

  Accordingly, when operating facilities for continuous production in parallel, many operators assigned to these facilities may require supervisory guidance at the same time. This is not preferable from the viewpoint of production efficiency due to a decrease in quality and productivity.

Means, assigning means for assigning an operator for operating the equipment for each equipment, skill level storage means for storing a skill level indicating the degree of skill for operating the equipment for each operator, equipment In The processing of the object to be processed in each facility is performed so that the number of consecutive points where the skill level of the assigned operator is less than the difficulty level calculated by the difficulty level calculation means is reduced at the same time. And a processing order determining means for determining the order.

  And the production schedule preparation method which concerns on the other one aspect | mode of this invention is a some equipment which processes in parallel, Comprising: Each equipment schedules each equipment which processes a several to-be-processed object continuously, respectively.

  In another aspect of the present invention, the production schedule creation device is a plurality of facilities that perform processing in parallel, and each facility creates a schedule for each facility that sequentially processes a plurality of objects to be processed. A production schedule creation device, for each workpiece, a workpiece information storage means for storing attributes of the workpiece, and for each piece of equipment, the workpiece and the workpiece Difficulty of calculating the degree of difficulty of processing at a continuous location where the workpieces to be processed are continuous based on the attributes stored in the workpiece information storage means of each of the workpieces continuous at the consecutive locations. A degree calculation means, a skill level storage means for storing a skill level indicating a degree of skill related to the operation of the equipment, for each operator assigned to each of the plurality of equipment for operating the equipment, Operators operating the equipment in each facility so that the number of consecutive locations where the skill level of the operator being operated is less than the difficulty level calculated by the difficulty level calculation means is reduced at the same time.

Will be able to. The fact that the number of such continuous parts occurring at the same time is small, the burden on the supervisor who guides the operator is reduced, and as a result, it is possible to improve quality and productivity.

  “Processing” is a general term for manufacturing activities that are performed in the process of manufacturing a processed object into a final product. For example, processing such as component adjustment is performed on the processed object, and casting is performed. Or rolling, and further annealing.

<Embodiment 1>
The production schedule creation device according to the embodiment can reduce the number of operators that the supervisor must instruct at the same time, in other words, the number of facilities as much as possible, when a plurality of facilities in the process of continuous production perform processing in parallel. The production schedule is reduced. Specifically, scheduling is performed so as to reduce the number of facilities that have difficulty in continuous production to exceed the skill level of the assigned operator.

<Difficulty of continuous production>
First, the difficulty of operation in continuous production will be described. Hereinafter, an object to be processed (operated) in the process will be referred to as an “object to be processed”.

  In general, the degree of difficulty of operation is defined such that the processing method of 'object A' is difficult.

  However, continuous production is characterized by the fact that products are manufactured and processed seamlessly (regardless of whether they are physically connected or not) in the facility, so that the processing of the workpiece itself is difficult. In addition, the processing may be difficult when the processing target β follows the processing target α. Examples of such a process (equipment) include a continuous casting machine, a rolling mill, and an annealing equipment.

  There are the following two factors for determining the degree of difficulty of processing in which the processing target β follows the processing target α. The first is the attributes of the object to be processed α and the object to be processed β, for example, the shape, the component, and the like. The second is the content of processing in the equipment, for example, the processing temperature, the speed of movement in the equipment (line speed), and the like.

  Hereinafter, the attribute information (substance, width, thickness, component, surface shape, strength, etc., if it is a plate) of the object to be processed in the facility, and the processing content in the facility (annealing temperature, cooling temperature, The line speed, plating process type, packaging process type, etc.) are collectively referred to as “processed object information”.

  The difficulty level of the operation is determined based on the difference between the workpieces α and β that are continuously processed.

  The degree of difficulty will be described using an example of an annealing facility for a plate (object to be processed) as equipment for performing continuous production. In a continuous annealing facility, a thin plate to be annealed is welded to a preceding thin plate on the entrance side of the facility. Thereby, a thin plate is passed and annealed one after another in the annealing equipment.

  For example, if the plate width, which is one of the attributes of the plate α and the plate β, is greatly different, the processing in the annealing equipment (for example, the annealing temperature, the cooling temperature, the processing speed, etc.) is exactly the same, but care must be taken for passing the plate. Is required and the difficulty of operation increases. On the contrary, the plates α and β have the same shape and components, but the annealing temperature and the cooling temperature may be different. At this time as well, care must be taken in the temperature management of the furnace and the cooling zone, which increases the operational difficulty.

  That is, the difficulty of operation in a continuous production process occurs in the process in the continuous location where the workpiece and the workpiece to be processed next to the workpiece are continuous. Specifically, there is a problem in processing when the processing is shifted from the processing content to be processed to the processing object before the continuous portion to the processing content to be performed on the subsequent processing object.

  Hereinafter, in the embodiment, as an example of an equipment for a process for performing continuous production, an annealing equipment for an iron manufacturing process or a non-ferrous metal manufacturing process will be described as an example, and the equipment that requires supervisor's guidance is reduced at the same time. An apparatus for creating a production schedule for improving productivity and quality will be described. In the embodiment, as shown in FIG. 1, the equipment 1 to the equipment 4 are operated in parallel and the number of supervisors is one, but the present invention is N (N: a natural number of 2 or more). In a production line having facilities, the present invention is applied to the case where at least N operators who operate at each facility are instructed by N-1 or less supervisors.

  Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

  In the continuous annealing step described in the embodiment, the preceding workpiece and the subsequent workpiece are physically connected (welded) and continuously processed. The same applies to the continuous casting process. However, the present invention is a process in which workpieces are processed intermittently, that is, without being physically connected, for example, in a process such as a converter, secondary refining, thin plate hot rolling, and thick plate rolling. Is also applicable.

A location where the processed product b is continuous is one of the continuous locations.

  When calculating the difficulty level of the connection location, it is calculated using two elements as described above in <Difficulty of continuous production>. That is, it calculates based on the attribute of a to-be-processed object, and the content of the process in an installation. In the embodiment, the degree of difficulty is calculated using the component of the object to be processed as the attribute of the object to be processed, and the degree of difficulty is calculated using the speed of the object to be processed moving within the facility as the processing content of the facility.

In the facility in the embodiment, a case will be described in which the speeds at two locations P1 and P2 in the facility need to be within the upper and lower limit values. If these places P1 and P2 are annealing facilities, for example, they are a heating zone and a cooling zone in the furnace, and the target value of speed, the upper limit value, and the lower limit value are determined in advance at each location.

  For example, “equipment 1” is set as the equipment 2211, “processing object a” is set as the processing object 2212, “component 1” is set as the item 2213, and “target value” is set as the category 2214. Since the value 2215 is set to “0.020%”, the target value of the component 1 included in the workpiece a processed by the facility 1 is 0.020%. . In the record in which “speed at P1” is set as the item 2213 and “target value” is set as the category 2214, “100 mpm” is set as the value 2215, so the position P1 in the equipment 1 The target value of the speed when the workpiece a moves is 100 m (meter) per minute.

Since “OK” is set as the “actual result”, “operator A” is set as the operator 2313 and “none” is set as the supervisor guidance 2314, it is difficult to cope with the component difference in the continuous portion of this table. The degree is “4”, the speed difference correspondence difficulty is “2”, and the operator A has operated accurately without the supervision of the supervisor.

This is a table that summarizes the results of each and is created for each operator. The component difference correspondence result table 2610 and the speed difference correspondence result table 2620 are created for each operator in the process in which the skill level calculation unit 1300 calculates the skill level of the operator, and stored in the skill level information storage unit 2600. The

Specifically, it is composed of “OK count”, “NG count”, and “success rate”. “OK number” indicates the number of successful operations without supervision of the supervisor, that is, the number of successes, and “NG count” indicates the number of times of non-accurate operation without the supervision of the supervisor. Show. “Success rate” indicates the success rate. In the embodiment, the success rate is obtained by the number of times of OK / (number of times of OK + number of times of NG) × 100.

  For example, “71.4%” is set as the “success rate” of the component adjustment record 2613 of the record in which “operator A” is set as the operator ID 2611 and “5” is set as the component difference correspondence difficulty 2612 In this case, the success rate of the operation with the difficulty level corresponding to the component difference of the operator A being “5” is “71.4%”.

  FIG. 11A shows an initial schedule 2410. The initial schedule 2410 is created by the one production schedule creation device 1000 and stored in the schedule storage unit 2400.

  The initial schedule 2410 describes, for each facility, assigned operators and objects to be processed in each unit processing period.

  For example, in the initial schedule 2410, the operator P is assigned to the facility 1, and the workpiece a is assigned as the workpiece to be processed in the first unit processing period starting from 10:00.

  FIG. 11B is a diagram illustrating an example of the configuration and contents of the determination result table 2420. This determination result table 2420 is a table indicating whether or not a supervisor is necessary for each continuous portion in the initial schedule 2410, created by the comparison determination unit 1400, and stored in the schedule storage unit 2400. Further, the determination result table 2420 is created for each schedule.

  The determination result table 2420 includes a processing order 2411, equipment 1 (2412), equipment 2 (2413), equipment 3 (2414), and equipment 4 (2415).

  The processing order 2411 indicates a unit processing period number.

  Facility 1 (2412) indicates whether or not there is a need for a supervisor at a continuous location in facility 1. The operators assigned to the equipment 1 are shown in parentheses. The facility 1 (2412) is composed of “processing object” and “necessity of instruction”, and “processing object” indicates a processing object assigned to the unit processing period indicated by the processing order 2411. “Necessary instruction” indicates the necessity of supervision by the supervisor, “◯” indicates necessity, and “×” indicates unnecessary. These “O” and “X” are set as “Necessary instruction” in the record in which the processing order 2411 is not set in consideration of the visibility of the table. The presence or absence of a supervisor's necessity shall be shown about the location where the to-be-processed object set as "is continued."

  Facility 2 (2413), Facility 3 (2414), and Facility 4 (2415) are each composed of “processed object” and “need to be instructed”, as well as facility 1 (2412). The processing object assigned to the unit processing period indicated by the processing order 2411 is shown, and “Necessity of guidance” indicates the necessity of guidance of the supervisor.

<Training necessity determination method>
Here, a method for determining whether or not the supervisor's guidance is necessary when the operator operates the facility will be described.

  This process is a process performed by the comparison determination unit 1400.

  The comparison / determination unit 1400 reads the difficulty level information table 2510 (see FIG. 5) indicating the difficulty level of each facility in succession from the difficulty level information storage unit 2500, and from the skill level information storage unit 2600, the skill level of each operator. The operator skill level table 2630 (see FIG. 10) in which the degrees are described is read out. Moreover, the operator arrange | positioned at each installation is acquired with reference to the initial schedule 2410 (refer Fig.11 (a)) memorize | stored in the schedule memory | storage part 2400. FIG.

  Then, for each connection location of each facility, it is determined whether or not supervisor guidance is necessary, and a determination result table 2420 (see FIG. 11B) is created and stored in the schedule storage unit 2400.

  Judgment compares each component difference difficulty and speed difference difficulty of consecutive locations with each component difference skill and speed difference skill of the operator located in the facility. In both cases, it is determined that the supervisor's guidance is unnecessary only when the skill level is higher than the difficulty level.

  For example, in the facility 4 of the initial schedule 2410, it is determined whether or not it is necessary to supervise the supervisor at consecutive locations of the workpieces to be processed in the second and third unit processing periods.

  In the difficulty level information table 2510-4 (see FIG. 5D) in which “equipment 4” is set as the equipment 2511, “second” is set as the processing order 2512, and “component difference correspondence” is set as the item 2514. Since “4” is set as the difficulty level 2515 in the set record, the difficulty level corresponding to the component difference at this continuous location is “4”. Similarly, since “2” is set as the degree of difficulty 2515 in the record in which “speed difference correspondence” is set as the item 2514, the speed difference correspondence difficulty at this continuous location is “2”.

In the facility 4, an operator S is arranged as indicated by an initial schedule 2410. Since “3” is set as the component difference correspondence 2632 and “4” is set as the speed difference correspondence 2633 in the record in which “operator S” is set as the operator ID 2631 in the operator skill level table 2630 The skill level corresponding to the component difference and the skill level corresponding to the speed difference of the operator P are “3” and “4”, respectively, and the following expressions are established.
Component difference correspondence skill (3) <component difference correspondence difficulty (4),
Speed difference correspondence skill (4)> Speed difference correspondence difficulty (2),
That is, since the skill level is insufficient for the item corresponding to the component difference, this continuous portion is determined as requiring guidance.

  Then, in the corresponding part of the determination result table 2420, here, the record between the record in which “second” is set as the processing order 2411 and the record in which “third” is set is included in the facility 4 (2415). “○” is set as “Necessary instruction”.

<Difficulty calculation method>
Next, the calculation method of the difficulty level of a continuous location is demonstrated using FIGS.

  First, a method of calculating the difficulty level corresponding to the component difference will be described. This process is a process performed by the component difference correspondence difficulty calculation unit 1210, and calculates the difficulty of the component difference correspondence operation when the workpiece is continuously processed. Hereinafter, the case where the to-be-processed object 1 and the to-be-processed object 2 are processed continuously is demonstrated to an example.

  The difficulty level is determined for a certain component included in the object to be processed from an allowable range included in the object 1 and an allowable range included in the object 2.

  In FIG. 6, the allowable range of the component 1 determined from the upper limit value and the lower limit value of the component 1 included in the workpiece 1 is indicated by C11. Similarly, the allowable range of component 1 contained in the workpiece 2 is C21. In addition, the allowable range of the component 2 included in the workpiece 1 is C12, and the allowable range of the component 2 included in the workpiece 2 is C22.

In the case where the object 1 and the object 2 are continuously processed, the difficulty level corresponding to the component 1 is defined as L1, and the value is defined as follows. The difficulty level is shown in four levels of 0, 1, 2, and 3. “0” is the lowest difficulty level and “3” is the highest level.
L1 = 0 if C11≡C21: Upper limit and lower limit are the same (the range is the same)
1 else if C11 ∈ C21 or C21 ∈ C11: One of the ranges is included in the other 2 else if C11 ∩ C21 ≠ φ: There is a common part 3 else: The relationship shown by these expressions without a common part 7 shows a correspondence table between the relationship between the allowable ranges and the difficulty level. When the allowable range C11 of the workpiece 1 and the allowable range C21 of the workpiece 2 match, the degree of difficulty is set to “0”, and the allowable range C11 is included in the allowable range C11 or is allowable in the allowable range C21. When the range C11 is included, the difficulty level is set to “1”. Further, when the allowable range C11 and the allowable range C21 partially overlap each other, the difficulty level is “2”, and when there is no overlap, the difficulty level is “3”.

  The definition of this difficulty level is the same component tolerance range, and when processing continuously, it is possible to cope with the same operation, so the difficulty level is low, and if it is different, there are elements that must be considered in the operation It shows that the level of difficulty increases.

Similarly, the difficulty level corresponding to the component 2 in the case where the workpiece 1 and the workpiece 2 are successively processed is defined as L2, and the value is defined as follows.
L2 = 0 if C12≡C22: Upper limit and lower limit are the same 1 else if C12∈C22 or C22∈C12: Either range is included in the other 2 else if C12 CC22 ≠ φ: Common part 3 else : There is no common part L is the total difficulty of dealing with component differences, taking into account both components 1 and 2 when processing object 1 and object 2 in succession, and the value is as follows: Defined in The overall difficulty level is shown in five levels of 1, 2, 3, 4 and 5, with “1” being the lowest difficulty level and “5” being the highest level.
L = 1 if L1 + L2 = 0
2 else if L1 + L2 = 1
3 else if L1 + L2 = 2
4 else if L1 + L2 = 3
5 else
The difficulty level corresponding to the component difference is determined according to the sum of the difficulty level corresponding to the component difference 1 and the difficulty level corresponding to the component difference 2. Specifically, if the sum is 0, the difficulty level L is “1”, if the sum is 1, the difficulty level L is “2”, if the sum is 2, the difficulty level L is “3”, and the sum is 3 Then, the difficulty level L is set to “4”. If the sum is 4 or more, the difficulty level L is set to “5”.

  For example, the difficulty level of the place where the workpiece a shown in the workpiece information table 2210a in FIG. 4A and the workpiece b shown in the workpiece information table 2210b in FIG. Ask for.

  In the workpiece information table 2210a, the value set as the value 2215 in the record in which “component 1” is set as the item 2213 and “upper limit value” is set as the category 2214 is “0.015%” Since the value set as the value 2215 is “0.010%” in the record in which the “lower limit value” is set as the category 2214, the allowable range of the component 1 of the workpiece a is “0.010%”. ˜0.015% ”. In the processing object information table 2210b, the value set as the value 2215 is “0.015%” in the record in which “component 1” is set as the item 2213 and “upper limit value” is set as the category 2214. Since the value set as the value 2215 is “0.010%” in the record in which the “lower limit value” is set as the category 2214, the allowable range of the component 1 of the workpiece b is “0. 010% to 0.015% ". Therefore, the allowable range “0.010% to 0.015%” of component 1 of the object to be processed a and the allowable range “0.010% to 0.015%” of component 1 of the object to be processed b match. The difficulty level L1 is 0 (see FIG. 7).

  Similarly, when the component difference is obtained for the component 2, the component difference of the component 2 of the workpiece a is “0.390% to 0.420%”, and the component difference of the component 2 of the workpiece b is “0. Since “370% to 0.380%” does not overlap, the difficulty level L2 is 3.

  Since L1 is 0 and L2 is 3, the sum of L1 and L2 is 3. Therefore, the total difficulty level L corresponding to the component difference is 4.

  Next, a method for calculating the difficulty corresponding to the speed difference will be described. This process is a process performed by the speed difference correspondence difficulty calculation unit 1220.

  Similar to the component difference correspondence difficulty, the speed difference correspondence difficulty is determined from the allowable range of the workpiece 1 and the allowable range of the workpiece 2 with respect to the moving speed of the workpiece.

  Similar to the allowable range C11 of component 1 shown in FIG. 6, the allowable speed range at P1 that can be derived from the upper and lower speed limits of the workpiece 1 at the location P1 is D11. Similarly, let D21 be an allowable speed range of the workpiece 2 at the place P1. Furthermore, the allowable speed range of the workpiece 1 at the place P2 is D12, and the allowable speed range of the workpiece 2 at the place P2 is D22. Each difficulty level correspondence difficulty is defined as follows in the same manner as in the case of the component.

The speed difference difficulty at the place P1 is set to V1.
V1 = 0 if D11≡D21: Upper limit and lower limit are the same 1 else if D11 ∈ D21 or D21 ∈ D11: One of the ranges is included in the other 2 else if D11 ∩ D21 ≠ φ: Common part 3 else : V2 is the speed difference difficulty at the place P2 where there is no common part.
V2 = 0 if D12≡D22: Upper limit and lower limit are the same 1 else if D12∈D22 or D22∈D12: Either range is included in the other 2 else if D12∩D22 ≠ φ: Common part 3 else : When there is no common part Processed object 1 and Processed object 2 are processed continuously, taking into account both the speeds of places P1 and P2, V is the overall speed difference difficulty, and the value is It is defined as follows.
V = 1 if V1 + V2 = 0
= 2 else if V1 + V2 = 1
= 3 else if V1 + V2 = 2
= 4 else if V1 + V2 = 3
= 5 else
The speed difference correspondence difficulty is determined according to the sum of the speed difference correspondence difficulty at the place P1 and the speed difference correspondence difficulty at the place P2. Specifically, if the sum is 0, the difficulty level V is “1”, if the sum is 1, the difficulty level V is “2”, if the sum is 2, the difficulty level V is “3”, and the sum is 3 Then, the difficulty level V is set to “4”. If the sum is 4 or more, the difficulty level V is set to “5”.

  For example, the speed difference at the place where the workpiece a shown in the workpiece information table 2210a in FIG. 4A and the workpiece b shown in the workpiece information table 2210b in FIG. Find the difficulty level.

  In the workpiece information table 2210a, the value set as the value 2215 in the record in which “speed at P1” is set as the item 2213 and “upper limit value” is set as the category 2214 is “110 mpm”, Since the value set as the value 2215 in the record in which the “lower limit value” is set as the category 2214 is “90 mpm”, the allowable range of the speed of the workpiece a at P1 is “90 mpm to 110 mpm”. . In the processing object information table 2210b, the value set as the value 2215 is “100 mpm” in the record in which “speed at P1” is set as the item 2213 and “upper limit value” is set as the category 2214. Yes, since the value set as the value 2215 is “90 mpm” in the record in which the “lower limit value” is set as the category 2214, the allowable range of the speed of the workpiece b at P1 is “90 mpm to 100 mpm”. It becomes. Therefore, the allowable range “90 mpm to 110 mpm” of the speed “P1” of the workpiece “a” and the allowable range “90 mpm to 100 mpm” of the velocity “P1” of the workpiece “b” are inclusive relation. (See FIG. 7).

  Similarly, when the allowable range of speed at P2 is obtained, the allowable range of speed at P2 of the workpiece a is “70 mpm to 100 mpm%”, and the allowable range of speed at P2 of the workpiece b is “70 mpm. Since “˜100 mpm%” match, the difficulty level V2 is zero.

  Since V1 is 1 and V2 is 0, the sum of V1 and V2 is 1. Therefore, the overall speed difference handling difficulty level V is 2.

  In the embodiment, the overall component difference correspondence difficulty L is determined by the value of the sum of L1 and L2, and the overall speed difference correspondence difficulty V is determined by the value of the sum of V1 and V2. However, other methods may be used, and the calculation method may be changed depending on the production facility. For example, a calculation method such as taking the maximum value or obtaining the product can be considered. Moreover, although the example in the case of two types of components and two places was shown, the case where the number of component types and places is one or more may be used.

  Moreover, you may obtain | require a difficulty level using items other than a component and speed as an attribute and process content of a to-be-processed object. For example, FIG. 19 is a diagram showing an example of the configuration and contents of the workpiece information table 2290, and shows an example of the workpiece information table 2290z of the workpiece z. Here, the item 2213 is constituted by “width” and “thickness” instead of “component 1” and “component 2”, and is constituted by “temperature” instead of “speed at P1”. The width indicates the width of the plate, the thickness indicates the thickness of the plate, and the temperature indicates the temperature at which processing is performed by the equipment. Furthermore, the attribute of the object to be processed, that is, the information as a substance includes the surface shape and strength, and the processing contents in the facility include a plating processing type and a packaging processing type.

<Skill level calculation method>
Next, a method for calculating the difficulty level of the operator will be described with reference to FIGS. 8 to 10 and 12.

  This processing is performed by the skill level calculation unit 1300.

  First, the skill level calculation unit 1300 creates a component difference correspondence result table 2610 and a speed difference correspondence result table 2620 for each operator from the operation result table 2310 stored in the operation result information storage unit 2300.

  Specifically, for each operator indicated by the operator 2313, the operation result table 2310 (see FIG. 8) is read, and the difficulty of the component difference correspondence 2311 when “none” is set as the supervisor guidance 2314. The number of results “OK” and “NG” for each degree is counted. In the component difference correspondence result table 2610 (see FIG. 9A), the number of “OK times” and “NG times” in the component adjustment results 2613 are set, the success rate is calculated, and the “success rate” is set. To do. Similarly, the number of achievements “OK” and “NG” for each difficulty level corresponding to the speed difference 2312 is counted. The number counted in each of “OK count” and “NG count” of the speed adjustment record 2623 of the speed difference correspondence record table 2620 is set, and the success rate is calculated and set to “success rate”.

  Next, the skill level calculation unit 1300 creates an operator skill level table 2630 from the component difference correspondence result table 2610 and the speed difference correspondence result table 2620 (see FIG. 9B) of each operator.

  The skill level is shown in five levels of 0, 1, 2, 3, and 4. “0” indicates that the skill level is the lowest, and “4” indicates that the skill level is the highest.

  Here, the concept of skill level will be described. When the success rate for each difficulty level of operation exceeds a predetermined threshold value, it is determined that supervision guidance is unnecessary for the operation at that difficulty level, and the skill level corresponding to that is given to the operator. However, the success rate of the lower difficulty level needs to exceed the threshold. In the embodiment, the degree of difficulty determined that the supervisor's instruction is unnecessary is the skill level. For example, if it is determined that the guidance of the supervisor is unnecessary if the component difference difficulty level is “3”, the skill level of the operator is “3”.

  For example, taking the component difference correspondence result table 2610 of FIG. 9A as an example, the operator A has a success rate of 100% in the case of the component difference correspondence work of difficulty levels 1 and 2 without supervisor guidance. . Therefore, it can be said that the operator A can sufficiently perform the component difference handling work up to the difficulty level 2. If the threshold is 95%, the success rate is 96.8% at difficulty level 3, 91.3% at difficulty level 4, and 71.4% at difficulty level 5. The person A can execute up to difficulty level 3 for the component difference handling work. The work skill level corresponding to the component difference, that is, the skill level corresponding to the component difference is determined as the skill level 3.

Note that the success rate of work with a low difficulty level is less than 95%, and conversely, the success rate of work with a high difficulty level is 95% or more. For example, if the number of failures at difficulty level 5 is 0, the success rate of the task for handling component differences at difficulty level 5 is 100%. There are various ways of thinking in such a case, but if the success rate in a task with a low difficulty level divides the threshold, it is assumed that a further skill level cannot be obtained. However, it is good also as giving the skill level more than that.

  The skill level calculation process will be described with reference to FIG. FIG. 12 is a flowchart of the skill level calculation process. The threshold is 95%.

  First, it is determined whether or not the success rate for difficulty level 1 is 95% or more (step S1). When it is determined that the success rate is less than 95% (step S1: NO), the skill level of operator A is defined as 0 (step S2). On the other hand, when it is determined that the success rate is 95% or more (step S1: YES), it is determined whether or not the success rate for the difficulty level 2 is 95% or more (step S3). When it is determined that the success rate is less than 95% (step S3: NO), the skill level of the operator A is defined as 1 (step S4). On the other hand, when it is determined that the success rate is 95% or more (step S3: YES), it is determined whether or not the success rate in the case of difficulty level 3 is 95% or more (step S5). When it is determined that the success rate is less than 95% (step S5: NO), the skill level of the operator A is defined as 2 (step S6). On the other hand, when it is determined that the success rate is 95% or more (step S5: YES), it is determined whether the success rate in the case of difficulty level 4 is 95% or more (step S7). When it is determined that the success rate is less than 95% (S7: NO), the skill level of the operator A is defined as 3 (step S8). On the other hand, when it is determined that the success rate is 95% or more (step S7: YES), it is determined whether or not the success rate in the case of difficulty level 5 is 95% or more (step S9). When it is determined that the success rate is less than 95% (step S9: NO), the skill level of the operator A is defined as 4 (step S10). On the other hand, when it is determined that the success rate is 95% or more (step S9: YES), the skill level of the operator A is defined as 5 (step S11).

  Further, from the speed difference correspondence result table 2620 of FIG. 9B, the operator skill level corresponding to the speed difference of the operator A, that is, the speed difference correspondence skill level can be similarly derived.

  The skill level of each operation of other operators is derived in the same manner as in the case of the operator A described above, and the operator skill level table 2630 is created.

  As described above, the operator skill level table 2630 is calculated from the component difference corresponding result table 2610 and the speed difference corresponding result table 2620 which are past operation results accumulated for each operator. The processing order can be determined based on the skill level evaluation.

<Operation>
Hereinafter, production schedule creation processing of the production schedule creation apparatus 1000 will be described with reference to the drawings.

  FIG. 13 is a flowchart of the production schedule creation process.

  First, the user inputs data necessary for production schedule creation processing via the input unit 1020 and stores the data in each storage unit. For example, the workpiece information table 2210 for each workpiece is stored in the workpiece information storage unit 2200.

  Next, the user inputs a command for instructing creation of a schedule via the input unit 1020.

  When the production schedule creation control unit 1010 receives a notification that a command for creating a schedule has been input (step S11: YES), the production schedule creation control unit 1010 instructs the initial schedule creation unit 1100 to start creating an initial schedule.

  Upon receiving the instruction, the initial schedule creation unit 1100 reads various information necessary for the production schedule creation process such as the scheduled start time table 2110 from the production plan information storage unit 2100 and creates a schedule. The initial schedule creation unit 1100 instructs the operator assignment unit 1110 to assign operators to the created schedule, create an initial schedule 2410 (see FIG. 11A), and store the schedule in the schedule storage unit 2400.

  Next, the production schedule creation control unit 1010 requests the skill calculation unit 1300 to calculate the skill level of each operator. At this time, the operator ID assigned to the initial schedule 2410 is passed.

  Upon receiving the request, the skill level calculation unit 1300 calculates the skill level for each operator of the passed ID and creates the operator skill level table 2630 as described in the section of <Skill level calculation method> above. Then, it is stored in the skill level information storage unit 2600 (step S12). For example, in the case of the initial schedule 2410, an operator skill level table 2630 in which four operators, operator P, operator Q, operator R, and operator S are registered, is created. Before starting the production schedule creation process, the skill level of all operators who can be arranged is calculated, and an operator skill level table 2630 in which all operators are registered is created to store skill level information. It may be stored in the part 2600. In this case, the process of step S12 becomes unnecessary.

  When the skill level calculation unit 1300 creates the operator skill level table 2630 and stores it in the skill level information storage unit 2600, the production schedule creation control unit 1010 calculates the difficulty level of the continuous parts of the initial schedule 2410. The calculation unit 1200 is instructed.

  Receiving the instruction, the difficulty level calculation unit 1200 reads the initial schedule 2410 from the schedule storage unit 2400, calculates the difficulty level of the continuous location of each facility, and determines the difficulty level information tables 2510-1 to 2510-1 (FIG. 5A to FIG. 5). (See (d)) is created and stored in the difficulty level information storage unit 2500 (step S13).

  Specifically, the difficulty level calculation unit 1200 detects a continuous part from the initial schedule 2410, and reads the workpiece information table 2210 of the identifiers of the workpieces before and after the continuous part from the workpiece information storage unit 2200. . Then, the read workpiece information table 2210 is passed to the component difference correspondence difficulty calculation unit 1210 and the speed difference correspondence difficulty calculation unit 1220 to calculate the component difference correspondence difficulty and the speed difference correspondence difficulty, respectively. Ask.

  The requested component difference correspondence difficulty calculation unit 1210 refers to the workpiece information table 2210 delivered from the difficulty calculation unit 1200, and as described in the above section <difficulty calculation method> The correspondence difficulty level is calculated, and the calculated component difference correspondence difficulty level is passed to the difficulty level calculation unit 1200. Similarly, the speed difference corresponding difficulty level calculation unit 1220 refers to the workpiece information table 2210 passed from the difficulty level calculation unit 1200 and corresponds to the speed difference as described in the section of <Difficulty level calculation method> above. The difficulty level is calculated, and the calculated speed difference correspondence difficulty level is passed to the difficulty level calculation unit 1200.

  The difficulty level calculation unit 1200 to which the difficulty level corresponding to the component difference and the difficulty level corresponding to the speed difference have been passed sets the passed difficulty level as the difficulty level 2515 of the corresponding continuous location in the difficulty level information table 2510 (see FIG. 5). To do. For example, in the facility 1 of the initial schedule 2410, when calculating the difficulty level of the place where the workpiece a to be processed in the first unit processing period and the workpiece b to be processed in the second unit processing period are continuous. Passes the workpiece information table 2210a and the workpiece information table 2210b to the component difference correspondence difficulty calculator 1210 and the speed difference correspondence difficulty calculator 1220, respectively. Upon receiving “4” as the component difference correspondence difficulty from the component difference correspondence difficulty calculation unit 1210 and “2” as the speed difference correspondence difficulty from the speed difference correspondence difficulty calculation unit 1220, the difficulty information table 2510. “4” is set as the difficulty level 2515 in the record in which “facility 1” is set as the equipment 2511, “first” is set as the processing order 2512, and “corresponding to component difference” is set as the item 2514. . Also, “2” is set as the difficulty 2515 in the record in which “facility 1” is set as the facility 2511, “first” is set as the processing order 2512, and “speed difference correspondence” is set as the item 2514. .

  When the difficulty level calculation unit 1200 creates the difficulty level information table 2510 and stores the difficulty level information table 2510 in the difficulty level information storage unit 2500, the production schedule creation control unit 1010 requires the comparison determination unit 1400 to receive guidance from the supervisor at each successive location. Ask to determine whether or not.

  Upon receiving the request, the comparison / determination unit 1400 compares the difficulty level of the continuous portion with the skill level of the operator, creates a determination result table 2420 (see FIG. 11B), and stores it in the schedule storage unit 2400. (Steps S14 and S15).

  Specifically, difficulty level information table 2510-1 to difficulty level information table 2510-4 are read from difficulty level information storage unit 2500, and operator skill level table 2630 is read from skill level information storage unit 2600. Then, as described above in the section <Method for determining necessity / unnecessary guidance>, for each successive location, the presence / absence of guidance by the supervisor at that location is determined, and a determination result table 2420 is created.

  When the comparison determination unit 1400 creates the determination result table 2420 and stores it in the schedule storage unit 2400, the production schedule creation control unit 1010 requests the processing order change unit 1500 to create a new schedule with a changed processing order.

  The processing order changing unit 1500 that has received the request creates a changing schedule that is a schedule in which the processing order has been changed, and stores it in the schedule storage unit 2400 (step S17). For example, there is a schedule of the processing order of the workpieces shown in the determination result table 2430 shown in FIG. 14A and the determination result table 2440 shown in FIG. In the schedule of the processing order of the objects to be processed shown in the determination result table 2430, the order of the objects to be processed in the equipment 4 of the initial schedule 2410 is changed (see colored portions). Specifically, in the initial schedule 2410, processing is performed in the order of “processing object j”, “processing object k”, and “processing object 1”, but the processing order shown in the determination result table 2430 In this schedule, “processing object 1”, “processing object k”, and “processing object j” are processed in this order.

  When the processing order changing unit 1500 stores the schedule whose processing order has been changed in the schedule storage unit 2400, the production schedule creation control unit 1010 performs the processes of steps S13 to S15 on the schedule created by the processing order changing unit 1500. Make it.

  When all patterns of the change schedule in which the processing order of the objects to be processed is changed, in the embodiment, 1296 schedule processes are completed (step S16: YES), the production schedule creation control unit 1010 simultaneously receives the guidance of the supervisor. The schedule with the fewest necessary continuous parts is selected as the optimal schedule (step S18), and the process is terminated.

  For example, in the determination result table 2420 (FIG. 11 (b)), when changing from the second object to be processed to the third object to be processed, two instruction facilities requiring the facilities 1 and 4 are generated. On the other hand, for example, as shown in the determination result table 2430 (FIG. 14A), the processing of the workpiece j to be processed first and the workpiece 1 to be processed third in the facility 4 When the order is changed from the order shown in the initial schedule 2410, the number of facilities that require guidance from the supervisor at the same time is one at maximum. It should be noted that the difficulty level when changing from the object to be processed j to the object to be processed k is equal to the difficulty level when changing from the object to be processed k to the object to be processed j. It is clear from the explanation in the section of Method>.

  Further, as shown in the determination result table 2440 (FIG. 14B), the processing order of the first processed object and the second processed object in the facility 1 is set in the initial schedule 2410. Even when the order is changed, the number of facilities that are simultaneously determined as instructional facilities is one at maximum. It can be said that the change schedule shown in the determination result table 2430 and the change schedule shown in the determination result table 2440 are better schedules than the initial schedule 2410.

In addition, there are 331,767 combinations of processing orders when processing four processing objects with four facilities, and there are about 200 million processing combinations when processing five processing objects. There are combinations of processing order. Therefore, in a production line equipped with four facilities, an optimum solution can be derived without algorithmic ingenuity up to about four workpieces to be processed in each facility. However, when the number of objects to be processed in each facility is more than that and the number of facilities provided in the production line is more than that, when determining the processing order of objects to be processed in each facility, for example, Simultaneously supervised by creating a change schedule that is closer to the optimal solution by adopting some algorithmic ingenuity such as genetic algorithm, simulated annealing method, branch and bound method, and methods such as using provisional solution by censoring calculation time It is necessary to reduce the number of schedules for determining the number of facilities that require guidance from the person. If there is a restriction on the processing order of the objects to be processed, the restriction is stored in the storage unit so that the processing order that violates the restriction does not become the final processing order.
<Embodiment 2>
In the first embodiment, the processing order of the objects to be processed in each facility is changed, and a schedule is created so that the number of connection points that require guidance from the supervisor is reduced at the same time. In the second embodiment, the number of connection points that require supervision by the supervisor can be increased by changing the operator who operates the facility without changing the processing order of the objects to be processed in each facility. Create a schedule that will decrease.

<Configuration>
A configuration of the production schedule creation device 3000 according to the second embodiment will be described.

  FIG. 15 is a diagram illustrating a functional block configuration of the production schedule creation device 3000.

  Here, among the functional units of the production schedule creation device 3000, those given the same reference numerals as the functional units of the production schedule creation device 1000 shown in FIG. 2 have the same functions. Therefore, the operator arrangement changing unit 3500 different from the production schedule creation apparatus 1000 will be described focusing on the difference.

  Operator placement changing unit 3500 has a function of sequentially creating a change schedule for all combinations of operators placed in each facility based on the initial schedule. In the embodiment, operators are arranged in four facilities, respectively. Therefore, as shown in “CASE 1” to “CASE 24” in the combination table of FIG. = 24 ways. Therefore, the operator placement changing unit 3500, when requested by the production schedule creation control unit 3010, creates a schedule that is one of 24 schedules and is not stored in the schedule storage unit 2400, The schedule is stored in the schedule storage unit 2400. In the second embodiment, for each of the 24 schedules, the number of facilities that need to be instructed at the same time is obtained, and the optimum schedule is determined.

  The data used in the production schedule creation apparatus 3000 according to the second embodiment is the same as the data used in the production schedule creation apparatus 1000 according to the first embodiment.

<Operation>
Hereinafter, the operation of the production schedule creation device 3000 will be described with reference to FIG.

  FIG. 17 is a flowchart of production schedule creation processing in the production schedule creation device 3000.

  In the flowchart of FIG. 17 and the flowchart of the first embodiment shown in FIG. 13, steps denoted by the same reference numerals perform the same processing. Therefore, the description will focus on the processing of steps with different reference numerals.

  A user inputs a command instructing creation of a schedule via the input unit 1020.

  When the production schedule creation control unit 3010 receives a notification that a command for creating a schedule has been input (step S11: YES), the production schedule creation control unit 3010 instructs the initial schedule creation unit 1100 to start creating an initial schedule.

  Upon receiving the instruction, the initial schedule creation unit 1100 creates an initial schedule 2410 (see FIG. 11A) and stores it in the schedule storage unit 2400.

  Next, the production schedule creation control unit 3010 requests the skill level calculation unit 1300 to calculate the skill level of each operator, and the skill level calculation unit 1300 that receives the request includes the item <Skill level calculation method> described above. As described above, the skill level for each operator of the passed ID is calculated, and the operator skill level table 2630 is created and stored in the skill level information storage unit 2600 (step S12).

  Next, the production schedule creation control unit 3010 instructs the difficulty level calculation unit 1200 to calculate the difficulty level of the continuous portion of the initial schedule 2410, and the difficulty level calculation unit 1200 that has received the instruction instructs the difficulty level information table 2510- 1 to 4 (see FIGS. 5A to 5D) are created and stored in the difficulty level information storage unit 2500 (step S13).

  Next, the production schedule creation control unit 3010 requests the comparison determination unit 1400 to determine whether or not it is necessary to supervise the supervisor at each continuous location. The difficulty level and the skill level of the operator are compared, and a determination result table 2420 (see FIG. 11B) is created and stored in the schedule storage unit 2400 (steps S14 and S15).

  When the comparison determination unit 1400 creates the determination result table 2420 and stores the determination result table 2420 in the schedule storage unit 2400, the production schedule creation control unit 3010 causes the operator placement change unit 3500 to create a new schedule in which the operator placement is changed. Ask.

  The operator placement changing unit 3500 that has received the request creates a change schedule that is a schedule in which the placement of operators is changed, and stores it in the schedule storage unit 2400 (step S27).

  When the operator placement changing unit 3500 stores the schedule in which the operator placement is changed in the schedule storage unit 2400, the production schedule creation control unit 3010 causes the processes of step S14 and step S15 to be performed for the new schedule. In the second embodiment, the reprocessing in step S13 that was performed in the first embodiment is not performed. This is because, in the second embodiment, unlike the first embodiment, the processing order of the objects to be processed by each facility is not changed, so that it is not necessary to recalculate the difficulty of processing the continuous portions.

  In all patterns of the schedule in which the arrangement of operators is changed, in the second embodiment, when the processing of 24 schedules is completed (step S26: YES), the production schedule creation control unit 3010 needs the guidance of the supervisor at the same time. The schedule with the smallest number of consecutive locations is selected as the optimal schedule (step S28), and the process is terminated.

As described above, in the second embodiment, as in the first embodiment, it is possible to suppress a decrease in productivity and quality due to insufficient guidance from the supervisor. Note that the production schedule creation device 3000 according to the second embodiment is compared with the production schedule creation device 1000 according to the first embodiment when the processing order of the objects to be processed cannot be changed or when the cost increases by changing the processing order. And useful.
