Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the field of assembly-type manufacturing of information equipment products and home electric appliances, at a work site consisting of a plurality of workplaces mainly focusing on manual work, grasp the work acquisition status of each worker. The present invention relates to an inter-workplace worker accommodation system that can cope with a change in production quantity by accommodating multi-skilled workers who can perform many operations between workplaces by saving labor and time.

[0002]

2. Description of the Related Art Conventionally, a factory in a manufacturing industry regards a series of production processes as a sum of simple operations by dividing the production process into small pieces.
It consisted of a conveyor-centered production line where each worker shared simple tasks. For such a conveyor line, line balancing is important in order to ensure a good line knitting efficiency as a whole. Here, the line organization efficiency is the ratio of the net work time in the entire line, and the net time of the work in the entire line for one work item is the time required for the work object to pass through the entire line. Is the value obtained by dividing by It can be said that the line knitting efficiency is a better value as its value approaches 1.
Line balancing refers to leveling of the load ratio for each of the divided simple tasks. For this reason, conventionally, various methods and algorithms for performing line balancing have been developed. For example, Mitsuru Kuroda, “Line Balancing and Its Applications,” pp. 41-74, Nikkan Kogyo Shimbun, 1984 (known example 1) discloses a conventionally developed line balancing method and algorithm. In a conveyor line, products are produced through a series of divided simple operations, and if the operation time required for each simple operation is not uniform, line balance (the load allocation status for each simple operation) deteriorates,
Line knitting efficiency decreases. Therefore, conventional line balancing methods and algorithms have been developed for the purpose of finding a division of the production process so that the operation time of each simple operation is as uniform as possible. Since the problem of line balancing is often a combinatorial optimization problem, Suresh et al., "A Genetic
algorithm for assembly li
ne balancing ", Production
Planning & Control, Vol. 7,
No. 1, pp. 38-46, 1996 (known example 2)
As disclosed in, for example, there is an example of solving a problem using the latest optimization method. In the above conveyor line, once the method of dividing the production process is determined,
The tact time of the conveyor line (interval time during which the product to be worked is put into the line) is determined accordingly, and the production capacity of the entire line is fixedly determined.

However, information equipment products and home electric appliances are
The cycle of new product development is short, and the demand (varieties and quantities) in the market fluctuates greatly. Conveyor lines whose production capacity is fixedly determined for such products as described above are difficult to cope with severe demand fluctuations. Therefore, recently, a system has been introduced in which each worker is in charge of a certain amount of work in the production process. These are referred to as a cell production system or a stall system, and are described in, for example, the article “Shocking of Conveyor Removal”, Nikkei Mechanical, No. 459, p
p. 20-38, 1995 (known example 3). With these methods, each worker becomes multi-skilled,
Since a series of completed operations can be performed, there is no need to consider the line balance between the divided operations, and there is no waste due to a reduction in line organization efficiency. Further, it is possible to flexibly cope with fluctuations in demand by increasing or decreasing the number of production work units called cells or food stalls or changing the arrangement of workers. Therefore, in such a cell production system or a stall system, the arrangement of workers at each production workplace such as a cell or a stall becomes an important problem.

[0004] On the other hand, when the range of work in each workplace such as a cell or a food stall is widened and complicated, a workplace that cannot be assigned without some level of experience or ability may be created. As a result, there are workplaces that can and cannot be assigned by workers. In order to reflect the information on the available workplaces for each worker in the workplace assignment, a list of available work for each worker, such as a star list and a skills certification table, is created and the workplace is assigned to each worker. There is a way to narrow down possible workplaces. For example, in the publicly known example 3, an example of a star chart in which the contents of work mastered for each worker is recorded is disclosed. Also, the article "The source of profit is in the factory", Factory Management, Vol. 40, no. 1
3, pp. 39-43, 1994 (known example 4),
A method is disclosed in which a skill certification table is created by mapping varieties that have been in charge of each worker and acquired work, and the worker arrangement is determined based on the table.

[0005]

However, with respect to a conventional production system using a conveyor line, considering the line balance,
Since the production process is divided and the production capacity is fixedly determined thereby, it is not possible to cope with a drastic demand fluctuation of information equipment products and home electric appliances. Therefore, Known Example 1
Also, in the second conventional example, a method and an algorithm for determining the process composition in the conveyor line are provided, but even if these methods are used, it is not possible to cope with severe demand fluctuation.

[0006] On the other hand, production methods such as a cell production method and a stall method can flexibly cope with demand fluctuations by increasing or decreasing the number of production workplaces and the arrangement of workers. At this time, it is necessary to consider a production workplace to which the worker can take charge.
Discloses a method for that. However, the star chart used in the publicly known example 3 records the work content mastered for each worker, and such information must be collected and recorded for all workers engaged in the target production process. No. In addition, the skill certification table used in the known example 4 has similar difficulties. In addition, when arranging workers using the skill certification table, the arrangement is determined while checking the suitability of each worker. There must be.

[0007] However, usually, a factory employs hundreds to thousands of workers in many cases, and it is necessary to prepare a star chart and a skill certification table as described above and to allocate workers based on them. It takes enormous effort and time to perform. As described above, if labor and time are required for arranging the workers, it becomes impossible to flexibly respond to demand fluctuation which is a feature of the cell production system or the stall system.

[0008] Actually, when the contents of the work constituting the production process are analyzed, it is possible to grasp the possibility of being in charge of the work without looking at the work acquisition status of each worker.
For example, in the production of information equipment products, those who have been engaged in the assembly work of equipment can also be in charge of the repair work of the equipment, or those who have been in charge of the assembly of the type A have more This is a case where a type B which is easy to assemble can also be in charge. In such a case, it is not necessary to know the status of individual work acquisition for each worker, and only by considering the work content of the workplace and the flexibility of workers between workplaces, the arrangement of workers It can be performed.

According to the present invention, the flexibility of workers between workplaces is set based on information as to whether skills can be diverted between works, and workers are allocated to each worker, which has been conventionally required. To provide a worker interworking system that can reduce the time and effort required to grasp the work acquisition status and the size of the device for storing them, and can flexibly respond to changes in production quantities. Aim.

[0010]

Means for Solving the Problems To solve the above-mentioned problems, a system for interworking workers according to the present invention is realized by the following configuration.

[0011] In a work site composed of a plurality of workplaces where manual work is mainly performed, a planned work quantity for each workplace is input, and a worker accommodation system for accommodating workers between workplaces. Stores the work to be performed in each workplace, the types of products produced in each workplace, the standard work hours for working on products per unit quantity in each workplace, and the working hours per day in each workplace Work data, work skill diversion possibility data indicating whether skills can be transferred between works according to the work content, the number of basic workers in each workplace, and the difficulty of interworking workers Storage means for storing evaluation score data for each workplace set to evaluate the degree, and the workplace data and the work skill diversion possibility data stored in the storage means To determine whether or not workers can be accommodated between workplaces, and to generate worker-to-workplace flexibility data indicating the possibility of worker accommodation between workplaces. From the setting means, the planned quantity, and the standard work time and the working hours per day stored in the storage means, calculate the required number of workers, which is the number of workers required in each workplace. The required number of workers per workplace to be calculated, the required number of workers calculated by the required number of workers per workplace calculation means, the number of basic placement workers per workplace and the number of evaluation points stored in the storage means. Based on the data and the inter-worker flexibility data generated by the worker flexibility setting means, the number of workers in each workplace after the relocation of workers is determined by the required worker Satisfy the number and each job , The total number of workers relocating from the workplace to another workplace and the total number of workers remaining in the workplace satisfying the condition that the total And an operator accommodation plan determining means for determining the number of workers to be relocated so that the evaluation on the result of the operator accommodation is the best.

In particular, the worker flexibility setting means includes:
Judgment that worker accommodation is possible only between two workplaces where the work type is the same and skills can be transferred between the work in the workplace, and data on worker interchangeability between workplaces is generated. It is conceivable to have the function of

In order to make it possible to more flexibly set the worker flexibility between the workplaces, the worker flexibility setting means includes the workplace data stored in the storage means and the work skill diversion possibility. A function that automatically determines whether or not workers can be interchanged between workplaces and generates inter-worker interchangeability data, and then modifies the inter-worker interchangeability data. Is also conceivable.

Further, in order to quantitatively evaluate the goodness of the worker accommodation plan, the worker accommodation plan determining means includes a workplace-specific required worker number calculated by the workplace-specific required worker number calculating means; Inter-worker worker interchange evaluation score data in which the number of workplace-based basic arrangement workers stored in the storage means, a combination of workplaces where workers can be interchanged, and a penalty value when an operator is interchanged for each combination are registered. In some cases, a function to determine the number of workers to be relocated or the number of workers to be allocated to each workplace may be provided so as to minimize the total penalty value due to worker flexibility.

[0015] Further, the worker accommodation plan determining means may include a required number of workers per workplace calculated by the required number of workers per workplace calculation means and a number of basic workplace workers per workplace stored in the storage means. Based on the combination of workplaces where workers can be accommodated and the penalty value when workers are interchanged for each combination, the interworker interchangeability evaluation score data is registered.
It is also conceivable to have a function of determining the number of workers to be relocated and the number of workers to be assigned to each workplace so as to minimize the total penalty value due to worker flexibility using the simplex method in linear programming.

Forty, the following steps S502 to S506
The start of a series of processes up to this is instructed.

In step S502, a combination of two workplaces for which interworker worker flexibility data 1103 has not yet been set is selected from the workplaces registered in the workplace data 1102.

Next, in step S503, it is checked whether the varieties of the combination in both workplaces are the same. If the varieties are the same, the process proceeds to step S504, and if they are different, the process proceeds to step S506.

If the process proceeds to step S 504, it is determined whether the work skill can be diverted based on the work skill diversion possibility data 1101 by looking at the work in both workplaces of the combination. If it is determined in step S504 that the work skill can be diverted, the process proceeds to step S505,
Otherwise, the process proceeds to step S506.

If the process proceeds to step S505, it is determined that the combination of the workplaces can accommodate the worker in the direction in which the work skill can be diverted. For example, since the type is the same between the workplace notebook PC assembly workplace and the notebook PC repair workplace, and the work skills can be diverted from the assembly to the repair, it is determined that the worker can be interchanged from the workplace. You.

When the processing in step S505 is completed, the flow advances to step S506 to determine whether there is a combination of workplaces that have not been processed yet. If there is a combination of workplaces that have not been processed yet, the flow returns to step S502. Otherwise, a series of processing ends.

As a result of the processing by the worker flexibility setting means 140 described above, inter-worker worker flexibility data 1000 as shown in FIG. 10 is obtained as data. The inter-worker worker flexibility data 1000 is a table having a FROM column 1001 composed of a plurality of columns in a column direction and a TO column 1002 composed of a plurality of columns in a row direction.
Each column of the FROM column 1001 stores an identifier (workplace number) indicating the workplace from which the worker has been accommodated and the name of the workplace. In each column of the TO column 1002, an identifier (workplace number) indicating the workplace to which the worker is accommodated is stored. Each element in the table is a flag indicating whether or not the worker can be accommodated from the workplace on the FROM side to the workplace on the TO side. If the accommodation is possible, 1 is registered, and if the accommodation is not possible, 0 is registered. . In particular,
For the sake of convenience, it is assumed that all accommodations from the same workplace to oneself are possible (flag 1). The matrix 1003 composed of the elements of this table as elements is referred to as an inter-worker worker flexibility matrix. In FIG. 10, for example, a notebook type P
It has been shown that it is possible to relocate a worker located at a C-assembly workplace to a laptop PC repair workplace, but not to a laptop PC inspection workplace.

And can be modified. In addition, for each combination of the workplaces where the workers are accommodated, the user can enter and set a penalty in the penalty column 1206 as an evaluation value indicating the difficulty level when the workers are accommodated. As a method of setting the penalty, for example, the following setting method can be considered. When the workers are accommodated, a penalty of 5 is given if the original workplace and the destination workplace belong to different sections. In addition, if the workplace of the loan source or the workplace of the loan destination is constituted by outsourcing to another company, 3 is given as a penalty. Further, when the workplace of the loan source and the workplace of the loan destination are in different buildings, 1 is given as a penalty. In addition, it is possible to set a penalty for each combination of the workplaces in which workers are accommodated, reflecting various circumstances. FIG. 13 shows that, for example, a worker can be accommodated from a notebook PC assembly workplace to a desk PC assembly workplace, but in this case, a penalty of 5 is charged every time one worker is accommodated. As shown in FIG. 13, after the user resets various settings, a cancel button 1

In each column of the TO column 1002, an identifier (workplace number) indicating the workplace to which the worker is accommodated is stored. Each element of the table is F
This flag indicates whether or not workers can be accommodated from the workplace on the ROM side to the workplace on the TO side. If the accommodation is possible, 1 is registered, and if the accommodation is not possible, 0 is registered. All flexibility from the workplace to itself is possible (flag 1)
This is the same as the inter-worker worker flexibility data 1000 in FIG. However, since it has been modified by the operator flexibility setting means 140, the table element 1003 in FIG. 10 and the table element 14 in FIG.
01 is different. Table element 14 in FIG.
A matrix having 01 as an element is referred to as an inter-worker worker flexibility matrix T.

FIG. 15 shows the contents shown in FIG. 14 so as to be easily understood. In FIG. 15, the arrow connecting the names of the workplaces indicates that the worker can be accommodated in that direction. In FIG. 15, it is shown that workers can be accommodated from the notebook PC assembly workplace to the notebook PC repair workplace, and workers can be interchanged from the notebook PC repair workplace to the notebook PC inspection workplace. I have. In FIG. 15, a desk-type PC
Workers can be accommodated from the assembly workplace to the desk-type PC repair workplace.
C indicates that workers can be accommodated in the inspection workplace. Up to this point, it is the same as FIG. 11 which shows the contents of FIG. 10 for easy understanding. In FIG. 15, it is further shown that workers can be exchanged from the notebook PC assembly workplace to the desk-type PC assembly workplace, and workers can be interchanged from the notebook PC assembly workplace to the desk-type PC repair workplace. Represents. Further, it indicates that workers can be accommodated from the notebook PC repair shop to the desk PC repair shop, and workers can be accommodated from the desk PC repair shop to the notebook PC repair shop. Further, it indicates that workers can be exchanged from the desk-type PC inspection workplace to the notebook-type PC inspection workplace.

The penalty set through the screen shown in FIG. 13 is stored as inter-worker interchangeability evaluation score data 1104 as shown in FIG. The interworker worker interchange evaluation score data 1104 is a table having a FROM column 1601 composed of a plurality of columns in a column direction and a TO column 1602 composed of a plurality of columns in a row direction. FROM column 1
In each column of 601, an identifier (workplace number) indicating the workplace from which the worker has been provided and the name of the workplace are stored. TO column 16
Each column of 02 stores an identifier (workplace number) indicating the workplace where the worker is accommodated. Each element in the table is a penalty, which is an evaluation score indicating whether or not the worker can easily be accommodated from the workplace on the FROM side to the workplace on the TO side, and is set through the screen of FIG. As the penalty, 0 is registered if the accommodation is easy, 1 is set if the accommodation is somewhat easy, 3 is set if the accommodation is somewhat difficult, and 5 is set if the accommodation is difficult. A matrix including the element 1603 in the table in FIG. 16 as an element will be referred to as an inter-worker worker evaluation score matrix P.

Next, referring to FIG. 17, the required number of workers for each workplace calculating means 120 and the means for determining a worker accommodation plan 130 of the inter-worker accommodation system 100 according to the present embodiment will be described.
Will be described. FIG. 17 is a diagram showing the required number of workers for each workplace calculating means 120 and the means for determining a worker accommodation plan 130 of the interworker worker accommodation system 100 according to the present embodiment.
6 is a flowchart showing the operation of the first embodiment.

First, in step S1701, the required number of workers by workplace calculating means 120 reads the workplace data 1102 stored in the storage means 110 and the workplace / product type planned quantity data 150 sent from outside.
In addition, the worker accommodation plan determination means 130 stores the storage means 110
Data 110 for the number of basic placement workers by workplace stored in the
5. The interworker worker accommodation possibility data 1103 and the interworker worker accommodation evaluation score data 1104 are read.

Next, in step S1702, the required number of workers for each workplace calculating means 120 determines in step S17.
01, the standard work time required to produce the work item per unit quantity for each workplace, the working time for each workplace, and the planned quantity data 150 for each workplace and type, among the workplace data read in 01. Then, the required number of workers for each workplace is calculated, and the required number of workers for each workplace data 160 is generated.

The planned quantity data 150 by workplace / product type shows the number of work items to be produced per day assigned to each workplace to be produced. The planned quantity data 150 by workplace / product type is updated every day and sent before the day before the work day. FIG. 18 shows an example of the data 150 of the planned quantity by workplace / product type. By workplace shown in FIG.
The type-specific planned quantity data 150 includes a type column 1801 composed of a plurality of columns, a workplace column 1802 corresponding to each column of the type column 1801, and a planned quantity column 1803 corresponding to each column of the workplace column 1802. And Each column of the type column 1801 stores the type of the work item. Each field of the workplace column 1802 stores the name of a workplace that works on the work target product of the type stored in the corresponding type column 1801. Each column of the planned quantity column 1803 stores the number of work items to be produced per day (planned quantity) in the workplace with the name stored in the corresponding workplace column 1802.

In calculating the required number of workers for each workplace, the required number of workers for each workplace 120 calculates the value calculated by the calculation “the planned quantity × the standard work time per vehicle ÷ the relevant work time”. The value rounded up to an integer value is obtained as the required number of workers in the workplace. FIG. 19 shows an example of the required number of workers by workplace data 160 obtained by the required number of workers by workplace calculation means 120. In FIG. 19, the required number of workers by workplace data 160 includes a workplace column 1901 composed of a plurality of columns, and a required worker number column 1902 corresponding to each column of the workplace column 1901. Each column of the workplace column 1901 stores a workplace name and an identifier (workplace number). Each column of the required number of workers column 1902 stores the number of required workers in the workplace having the identifier and name stored in the corresponding column of the workplace column 1901. For example, the required number of workers in the notebook PC assembly workplace is as follows: the standard work time 20.0 minutes per work and the work time 465.0 minutes / day in the workplace data 1102 shown in FIG.
180 × 20.0 ÷ 46 using the planned quantity 180 units / day of the planned quantity data 150 by workplace / type shown in FIG.
5.0 = 7.742, which was rounded up to 8
It is calculated as a person. In FIG. 19, consider a vector having the number of workers 1903 stored in each column of the required number of workers column 1902 of the required number of workers by workplace 160 as an element, and this vector is referred to as a vector R.

Next, in step S1703, the worker accommodation plan determining means 130 determines the required worker number data 160 for each workplace calculated by the required workplace number calculating means 120 in step S1702 (see FIG. 19).
And the workplace-based basic arrangement worker number data 1105, the workplace interworker flexibility data 1103 (see FIG. 14), and the workplace interoperability evaluation score data 1104 (see FIG. 16) read in step S1701. Then, a plan of the number of workers to be exchanged (placed) between the workplaces (this plan is referred to as a worker accommodation plan) and the number of workers to be arranged for each workplace after the transfer are determined.

The basic arrangement worker number data 1105 means a basic arrangement worker number in a case where workers are not interchanged between workplaces. Specifically, it is the number of workers initially assigned to each workplace, or the number of workers assigned as suitable for work in each workplace.
FIG. 20 shows an example of the data 1105 on the number of basic placement workers by workplace. Data on the number of basic workers by workplace 1105
Is a workplace column 2001 composed of a plurality of columns, and a basic worker number column 20 corresponding to each column of the workplace column 2001.
02. Each column of the workplace column 2001 stores a workplace name and an identifier (workplace number). Each column of the number of basic workers column 2002 stores the number of basic arrangement workers in the workplace having the identifier and the name stored in the corresponding column of the workplace column 2001. In FIG. 20, for example,
One worker was initially assigned to the notebook PC assembly workplace.
It indicates that there are five people. In FIG. 20, the number of basic workers column 200 in the data 1105 of the number of basic placement workers by workplace.
2 is considered as a vector having the number of basic arrangement workers 2003 stored in each column as an element.
Shall be referred to as

In the present embodiment, step S17
The process of determining the worker accommodation plan of the worker accommodation plan determining means 130 in 03 is performed by applying the simplex method of the linear programming method. The worker accommodation plan is determined so as to minimize the sum of penalties caused by the worker accommodation. At this time, (1) the condition that the relocation of workers from a certain workplace must be less than or equal to the basic number of workers in the workplace shown in FIG. 20 and (2) each workplace after the relocation of workers Is considered to satisfy the condition that the number of arrangement workers must match the required number of workers shown in FIG.
Vector R indicating the required number of workers for each workplace shown in FIG.
(The element is ri, and i is an integer from 1 to 6), a vector B indicating the number of basic placement workers by workplace shown in FIG.
(Element is bi, i is an integer from 1 to 6), a matrix T showing the flexibility of workers between workplaces shown in FIG.
(Elements are tij, i and j are integers from 1 to 6). A matrix P (elements are pij and i, j are the penalties when workers are interchanged between the workplaces shown in FIG. To
Using integers from 1 to 6), the problem of determining a worker accommodation plan in the present embodiment is that the element xij of the matrix X having the element xij as shown in the following equation (Equation 1) Is expressed as a linear programming problem. Here, a matrix X (elements are xij, i and j are integers from 1 to 6) is obtained from the workplace of workplace number i by the workplace number j
Factor xi, the number of workers who relocate to the workplace
j is a matrix. It should be noted that the element xij is the number of workers who change the layout, so it is unlikely that the element xij becomes negative.

[0064]

(Equation 1)

In (Equation 1), the first expression is called an evaluation function, and the second and third expressions are called constraint expression. The evaluation function means a total penalty (sum of penalties) when the operator is accommodated. The constraint condition expression of the second formula is the condition of the above (1), and the constraint condition expression of the third formula is the above. Each of the conditions (2) is meant. The problem of determining a worker accommodation plan in the present embodiment is as follows.
A non-negative x that satisfies the constraint expression shown in (Equation 1) and minimizes the evaluation value that is the value of the evaluation function shown in (Equation 1)
ij is expressed as a linear programming problem. (Equation 1)
When the values of the respective elements of the matrix P, the matrix T, the vector B, and the vector R are substituted into the linear programming problem shown in (1), an evaluation function and a constraint expression such as (Equation 2) are obtained.

[0066]

(Equation 2)

In order to process the problem by the simplex method, first, the seventh constraint expression in (Equation 2) is substituted into the first constraint expression, and then a slack is added to the inequality constraint expression. When the variables y1 to y6 are added to the constraint equation, which is an equation, and the fine variables y7 to y11 are respectively added, a sufficiently large real number M is introduced, and the evaluation function is rewritten into a maximized form. This is expressed as a constraint expression.

[0068]

(Equation 3)

The problem rewritten as (Equation 3) is
This can be solved by using the well-known simplex fine method, and the initial simplex table is shown in FIG. The simplex method is described in, for example, “Example Solution OR Approach to Decision Making” (published by Tadashi Owada and Yutaka Kato, Jikkyo Shuppan). Details are described in 1-29.

In FIG. 21, the values in the column of wi are coefficients in the evaluation function of (Equation 3) of the base variable corresponding to each column. Further, the values in the columns of wj are coefficients in the evaluation function of (Equation 3) of the variables corresponding to each column. The values in the cells from the first row to the eleventh row are coefficients for the respective variables in the first to eleventh constraint expression in (Equation 3). It is considered that 0 is stored in a cell in which a numerical value is not stored. zj
Is a value obtained by summing the values obtained by multiplying the numerical values in the cells of the column by the values of wi in the row corresponding to the cell for all the cells in the column. For example, FIG.
In the column of x12, since 1 is entered in the first row and 1 is entered in the seventh row, 0 × 1 + (− M × 1) = − M is obtained and entered in the column of zj. For each numerical value in the column of θ, first, select one column having the largest value among the numerical values in the column of wj-zj, and use the numerical value in each cell of the column to calculate the constant term of the row of the cell. It is determined by dividing the value.
For example, in FIG. 21, the fourth column (column of x22 surrounded by a circle) which is the maximum at wj−zj = M (triangle mark in the diagram) is selected, and θ = 7 ÷ 0 = ∞, for the second row, θ = 10 ÷ 1 = 10, etc. When θ has been obtained for all the rows, the row having the minimum value of θ is selected and its base variable is set as a non-base variable, and at the same time, the variable of the column whose wj-zj value previously selected is the maximum is newly added. Basic variables. For example, in FIG. 21, the row having the minimum value of θ is the seventh row (triangle mark in the figure), the base variable y7 is a non-base variable, and the variable x22 of the previously selected column is It becomes the base variable. At this time, a pivot operation in the simplex method is performed to make x22 a base variable. That is, among the coefficients of the variable (x22) to be newly set as the basis variables, the coefficient at the intersection between the base variable and the variable (y7) to be the non-base variable is set to 1, and the other coefficients are set to 0.

By the above processing, the simplex table of FIG. 21 is rewritten to the simplex table of FIG. Hereinafter, the same procedure described in the simplex table of FIG. 21 is repeated, and the simplex table is rewritten until all the values of wj-zj in the simplex table become 0 or less (until there is no room for improvement of the evaluation function value). To go. FIG. 22 to FIG. 31 are simplex tables obtained in the process of solving a problem by the simplex method in the present embodiment. In FIG. 31, all w
Since the value of j-zj is 0 or less, it can be seen that the optimal solution has been reached. The optimal solution of (Equation 3) can be obtained if each value of the basis variable in the simplex table in FIG. 31 takes the value in the column of the corresponding constant term. That is, y1 = 2, x
23 = 3, x33 = 5, x45 = 0, x55 = 6, x6
6 = 8, x22 = 7, x12 = 1, x44 = 10, x1
5 = 4, x56 = 2, and other variables = 0 are optimal solutions. In addition, from the seventh constraint expression of (Equation 2), x1
1 = 8. However, a variable having the same subscript (for example, x33) or a slack variable (for example, y1) has no relation to the transfer of workers between workplaces.

FIG. 32 is an explanatory diagram showing the relocation of the workers based on the optimal solution obtained in FIG. In FIG. 32, the notebook PC assembly workplace
One person in the repair workplace (x12 = 1), four people from the notebook PC assembly workplace to the desk type PC repair workplace (x15 = 4),
The figure shows that three people (x23 = 3) are transferred from the notebook PC repair shop to the notebook PC inspection workplace, and two people (x56 = 2) are transferred from the desk PC repair workplace to the desk PC inspection workplace. The evaluation value (sum of penalties) at this time is 26. This evaluation value is obtained by substituting the value of the optimal solution obtained in FIG. 31 into the evaluation function shown in (Equation 2).

FIG. 33 shows the same data (vector R,
FIG. 10 is an explanatory diagram showing an example of a worker rearrangement based on a worker accommodation plan created by a human being based on a vector B, a matrix T, and a matrix P). In FIG. 33, a notebook PC
5 people from the assembly workplace to the desk PC repair workplace, 2 people from the notebook PC repair workplace to the notebook PC inspection workplace,
From desk type PC repair workplace to desk type PC inspection workplace 3
This shows that one person has been switched from a desk-type PC inspection workplace to a notebook-type PC inspection workplace. According to this, the evaluation value is 35, and the penalty is larger than the optimal solution shown in FIG. 32, which is not preferable.

Finally, in step S1704 of FIG. 17, the worker accommodation plan determination means 130 outputs the finally determined number of relocation workers for each workplace as data 170 for the number of relocation workers for each workplace. . Further, the number of placement workers for each workplace is output as workplace-based placement worker number data 180, and the series of processing is terminated. As the workplace-specific relocation worker number data 170, for example, the value of xij obtained as an optimal solution may be output. Alternatively, a diagram as shown in FIG. 32 may be output. Number of workers arranged by workplace 1
As 80, for example, data as shown in FIG. 34 can be output. The workplace number of workers by workplace data 180 shown in FIG.
401, and a number of placement workers column 3402 corresponding to each column of the workplace column 3401, respectively. Each column of the workplace column 3401 stores a workplace name and an identifier (workplace number). Each column of the number of arrangement workers column 3402 stores the number of arrangement workers after the worker interchange in the workplace having the identifier and the name stored in the corresponding workplace column 3401.
The number of allocated workers after the worker accommodation is calculated by dividing the number of basic workers stored in the number of basic workers 2202 of the number of basic allocated workers 1105 shown in FIG. It can be obtained by changing the number data 170 according to the number of transfer workers. For example, the number of basic workers in the notebook PC assembly workplace is 15 according to FIG.
Since one person is assigned to the repair workplace and four people are changed from the notebook PC assembly workplace to the desk-type PC repair workplace, the number of workers arranged in the notebook PC assembly workplace is ten as shown in FIG.

As described above, the interworker worker interchange system 100 according to the present invention enables the arrangement of workers corresponding to the planned production quantity without having to grasp the work acquisition status of each worker as in the related art. In the present embodiment, if the work acquisition status of each worker is registered in order to determine the arrangement of the workers, the maximum number of workers (56) × the number of workplaces (6 workplaces) = 336 It is necessary to have the results of the survey as data. On the other hand, if the inter-workplace worker accommodation system 100 according to the present invention is used, the work skill diversion possibility data 1101 can be interchanged among the workplaces (the number of work (3 work) × the number of work (3 work)) = 9. Sex data 1103 is the number of workplaces (6 workplaces) x the number of workplaces (6 workplaces) = 3
Since only the data of the number of the workplaces (6 workplaces) × the number of the workplaces (6 workplaces) = 36 cases need to be registered as the 6 workplace worker interchange evaluation data 1104, the required data capacity is 4 minutes even if it is simply considered. 1 (336 ÷ 81) or less.
Actually, the data of the work learning status for each worker includes many attributes and the size per record becomes large, whereas the interworker worker interchange system 10 according to the present invention is used.
Since the work skill diversion possibility data 1101 and the inter-worker interchangeability data 1103 need only be a flag (a one-digit character string or a numerical value), the effect can be further improved.

[0076]

According to the worker interworking system according to the present invention, the possibility of worker interchange between workplaces is set based on information on whether skills can be transferred between works and workers are arranged. In addition, it is possible to reduce the trouble and time required for grasping the work acquisition status of each worker and the scale of a device for storing them, thereby enabling a flexible response to a change in production quantity.
