Abstract

The present invention provides product delivery deadline compliance and increased worker training efficiency. A worker assignment scheme creation section of a worker assignment device creates a worker assignment scheme and calculates a job completion time for each process step of each product in accordance with a worker assignment rule. An evaluation value calculation section calculates evaluation values concerning delivery deadline compliance and worker training in accordance with processing results produced by the worker assignment scheme creation section. A worker assignment priority change section changes the worker assignment rule in accordance with the evaluation values and target values therefor. The above process is repeated a number of times to produce plural worker assignment schemes, which are compared in accordance with the evaluation values concerning delivery deadline compliance and worker training. The result of comparison is eventually presented to a user.

Claims

a storage;

a controller;

an input section;

a display; and

a communication section;

wherein the controller includes

an information acquisition section that acquires product information identifying a product-specific delivery deadline and process path, process step information, product-specific in-progress process step information, work information about workers, working time information about workers, training target time information about workers, processing priority information concerning products and process steps, and assignment priority information concerning products, process steps and workers from an external system through the communication section and stores the acquired information in the storage,

a worker assignment scheme creation section that performs a process for creating a worker assignment scheme for each process step of each product and a process for calculating a job start time and job completion time for each process step of each product in accordance with the processing priority information and the assignment priority information,

a work history information storage section that stores work history information created by the worker assignment scheme creation section in the storage, the work history information including worker assignment information and job start time information and job completion time information about each process step of each product,

an evaluation value calculation section that performs a process for calculating a delivery deadline compliance evaluation value indicative of the percentage of delivery deadline compliance in accordance with the worker assignment information, the job start time information, the job completion time information, and product-specific delivery deadline information, and a process for calculating a worker training evaluation value indicative of the percentage of training goal achievement in the worker assignment scheme in accordance with the result of worker assignment scheme creation and training goal information about each worker, and

a worker assignment priority change section that performs, in accordance with processing results produced by the evaluation value calculation section, a delivery deadline compliance percentage target value, a worker training goal achievement percentage target value, and the working time information about each process step of each worker, a process for applying a worker assignment priority change so as to preferentially assign workers whose working time is relatively short to a process step of a delivery-deadline-overdue product if the delivery deadline compliance evaluation value has not reached a target value, and preferentially assign workers whose working time is relatively long to a process step of a delivery-deadline-compliant product if the worker training evaluation value has not reached a target value, and causes the display to perform a process for displaying plural worker assignment schemes for comparison purposes by simultaneously displaying the delivery deadline compliance evaluation value and the worker training evaluation value, which are the processing results produced by the controller.

4. The worker assignment device according to claim 1, wherein the worker assignment priority change section performs a process for producing a delivery-deadline-overdue product having the minimum or maximum time overdue from a delivery deadline as a product for applying a worker assignment priority change.

5. The worker assignment device according to claim 1, wherein the worker assignment priority change section performs a process for producing a delivery-deadline-compliant product having the minimum or maximum time remaining before a delivery deadline as a product for applying a worker assignment priority change.

6. The worker assignment device according to claim 1, wherein the worker assignment priority change section performs a process for giving the highest assignment priority to a worker having the minimum or maximum working time in a process step of a product to be subjected to an assignment priority change.

7. The worker assignment device according to claim 1, wherein the worker assignment priority change section performs a process for extracting, in a process step of a product to be subjected to an assignment priority change, a worker having the highest assignment priority from workers whose working time is shorter or longer than the working time of workers assigned before an assignment priority change and giving the extracted worker higher assignment priority than the workers assigned before the assignment priority change.

2. A computer readable medium storing a worker assignment program causing a computer to function as a worker assignment device and execute a process for assigning workers to various jobs involved in a manufacturing process, wherein the computer includes a control unit and a display unit, the process comprising:

causing the control unit to perform a process for creating a worker assignment scheme for each process step of each product in accordance with worker assignment rule information, a process for calculating a job completion time for each product, a process for calculating a delivery deadline compliance evaluation value indicative of the percentage of delivery deadline compliance in accordance with the calculated job completion time and delivery deadline information about each product, a process for calculating a worker training evaluation value indicative of the percentage of training goal achievement in the worker assignment scheme in accordance with the result of worker assignment scheme creation and training goal information about each worker, and a process for applying a worker assignment rule change, in accordance with processing results produced by the evaluation value calculation section, a delivery deadline compliance percentage target value, a worker training goal achievement percentage target value, and the working time information about each process step of each worker, so as to preferentially assign workers whose working time is relatively short to a process step of a delivery-deadline-overdue product if the delivery deadline compliance evaluation value has not reached a target value, and preferentially assign workers whose working time is relatively long to a process step of a delivery-deadline-compliant product if the worker training evaluation value has not reached a target value; and

causing the display unit to perform a process for displaying plural worker assignment schemes for comparison purposes by simultaneously displaying the delivery deadline compliance evaluation value and the worker training evaluation value, which are the processing results produced by the control unit.

3. A worker assignment system that assigns workers to various jobs involved in a manufacturing process, the system comprising:

a controller; and

a display;

wherein the controller includes

a worker assignment scheme creation section that performs a process for creating a worker assignment scheme for each process step of each product and a process for calculating a job completion time for each product in accordance with the worker assignment rule information,
