Description

  The present invention is continuously processed for electronic device products such as semiconductor elements, magnetic storage devices, flat displays, and printed circuit boards, and industrial machine products such as automobiles, elevators, escalators, and construction machines, oil refineries, pharmaceuticals, and food processing. The present invention relates to a worker placement support apparatus and a worker placement support system in a manufacturing site for products.

  In order to improve production efficiency in a production line in which an operator holds a plurality of devices and a product is handled manually, it is necessary to optimize the number and arrangement of workers. However, in a production line in which many kinds of products are mixed, since the arrangement of production processes differs depending on the kind, the arrival of products at each process varies, and the load on the production apparatus fluctuates. In addition, because the production capacity of each process varies depending on the worker's attendance, etc., the production indicators such as throughput, manufacturing lead time, and the amount of work in progress in each process and each device are the number of workers. It is difficult to predict when it will worsen due to lack.

  As a background art of this technical field, there is JP 2009-289056 A (Patent Document 1).

  Also, the worker placement support system 100 of the present invention provides information to a CPU 901, a memory 902, an external storage device 903 such as an HDD, and a portable storage medium 904 such as a CD or DVD as shown in FIG. A reading device 905 that reads and writes data, an input device 906 such as a keyboard and a mouse, an output device 907 such as a display, and a communication device 908 that communicates with other computers via a communication network such as the Internet. It can be constructed on a computer system having a general configuration including a bus or the like, or a network system including a plurality of computer systems.

  Next, processing executed by the worker placement evaluation apparatus 110 according to the embodiment of the present invention will be described in order with reference to FIG.

  FIG. 13 is a flowchart illustrating processing executed by the worker placement evaluation apparatus 110 according to the embodiment of the present invention.

  First, the information acquisition management unit 1121 stores, from the storage unit 111, process route information, manufacturing device stop plan, input plan, work in progress information, manufacturing device information, worker information, work shift plan, worker work schedule for all products. The plan is read as input data (S10).

  Next, the production simulation unit 1122 performs a production simulation for the designated planning period from the present information to the future from the information of only the process route information, the manufacturing device stop plan, the input plan, the in-process information, and the manufacturing device information. The progress plan (A) for the product is prepared (S20). In the production simulation executed here, worker information, work shift plan, and worker work plan are not input, so in the progress plan (A) of the product to be created, worker waiting time occurs in all devices. do not do. Therefore, the processing waiting time in the progress plan (A) consists only of the processing waiting time due to the stop of the apparatus and the processing waiting time of other products.

  Next, the worker simulation unit 1123 designates process route information, manufacturing equipment stop plan, input plan, work in progress information, manufacturing equipment information, worker information, work shift plan, and worker work plan from the present to the future. A production simulation for the planned period is performed, and a progress plan (B) for all products and an accompanying work plan for the worker are created (S30). In the production simulation executed here, worker information, work shift plan, and worker work plan are input. In the progress plan (B) of the product to be created, depending on the work situation of the worker, Latency may occur. Therefore, the processing waiting time in the progress plan (B) includes a processing waiting time due to the stop of the apparatus, a processing waiting time for other products, and a worker waiting time.

  Next, the operator excess / deficiency evaluation unit 1124 calculates the throughput and manufacturing for each device, each process, and each area, which is totaled in units of work shifts for each of the progress plan (A) and the progress plan (B). Statistical values such as the sum of production indices such as the lead time and the amount of work in progress, the average value, the median value, and the standard deviation value are calculated (S40).

Next, the worker excess / deficiency evaluation unit 1124 specifies, for each work shift i, the statistical value of the production index in the progress plan (A) and the progress plan (B) defined by the following equation (1). A difference ΔMI _i with the statistical value of the production index is calculated (S50).

(Equation 1)
ΔMI _i = MI (B) _i -MI (A) _i (1)

Here, i is an index that specifies a work shift. MI (A) _i is a statistical value of the production index designated by the work shift i in the progress plan (A). MI (B) _i is a statistical value of the production index designated by the work shift i in the progress plan (B).

Next, the worker excess / deficiency evaluation unit 1124 calculates, for each work shift i, an average change rate of ΔMI _{i in} the shift i defined by the following equation (2) (S60).

(Equation 2)
(Average rate of change of _{ΔMI i) = (ΔMI i -} ΔMI i-1) / (t i - t i-1) ··· (2)

Here, t _i is the end time of work shift i.

  Next, the worker excess / deficiency evaluation unit 1124 outputs the results of step S50 and step S60, for example, in the form of an output screen 200 described later (S70).

  FIG. 14 is a schematic diagram of an output screen 200 that is an example of output information of the worker placement evaluation apparatus according to an embodiment of the present invention.

  The output screen 200 includes an area selection area 200a, a production index selection area 200b, a threshold selection area 200c, a selection unit 200d, and a result display area 200e.

  First, in the output screen 200 displayed on the output unit 114, an input is received in the plan area selection area 200a, an input is received in the production index selection area 200b, and an input is further input in the threshold selection area 200c. When the acceptance and selection unit 200d is pressed, the data output in step S70 of the worker excess / deficiency evaluation unit 1124 is output to the result display area 200e.

Here, the operator excess / deficiency evaluation unit 1124 applies ΔMI _{i for} each work shift i with respect to the production index specified in the production index selection area 200b for all devices existing in the area specified in the area selection area 200a. The value of is output. At the same time, the worker excess / deficiency evaluation unit 1124 emphasizes the cell of the work shift i in which the average change rate of ΔMI _i satisfies the condition specified in the threshold selection area 200c, for example, by texture display.

  By displaying such an output screen 200 on the output unit 114, the manufacturer who organizes the work shift of the worker can, for example, work corresponding to the emphasized cell based on the output of the result display area 200e. By reviewing the shift plan, it is possible to prevent the production index from deteriorating due to workers.

  Further, it is possible to configure the output screen 200 so that the user can confirm the selected evaluation result and change the work shift plan.
