PRODUCTION LINE CONSTITUTION EVALUATING DEVICE AND METHOD OF CONSTRUCTING PRODUCTION LINE BY USING THIS PRODUCTION LINE CONSTITUTION EVALUATING DEVICE

摘要

PURPOSE: To automatize optimization in the case of design-changing a production line, in a device whereby a plan of short preparing period further with a small number of sets of necessary equipment can be searched at a high speed. CONSTITUTION: A production line constitution evaluating device 1 comprises the first input device 1, second input device 2, third input device 3, production line constitution evaluating simulator 4, data base 5, equipment part data preparing device 6, equipment ability comparing device 7, equipment layout device 8 and CAD 9. From a processing form of equipment, processing time, preparation rearrangement, maintenance time (stagnation time), frequency and a trouble factor, input from the second input device 2, a rate of operation and equipment ability are calculated by the production line constitution evaluating simulator 4, and by inputting a number of target production lots and a number of modules, a module constitution is determined to calculate a period of manufacture and a number of sets of equipment. As a solving method of combination, genetic algorithm is applied. A processing flow is divided by a fixed rule, to prepare a work group. In what module this work group is processed serves as a gene.
