The Investigation Of Production Management Styles And Job Scheduling Problem In Production System

Facing to manufacturing system, this paper analyzed its characters and evolvement of production management modes, demonstrated that lean production and human-based theory were practical ways to reform our manufacturing systems fit for the reality. A division method was raised to separate the job-scheduling problem into SHOP and STATION types, and emphasis was pressed on the study of partheno-genetic algorithm (PGA), a revised genetic algorithm, to calculate this problem. A new kind of gene joint-move algorithm was also raised. The validity and superiority were demonstrated. Then the paper investigated how to apply the PGA into job-scheduling problem of manufacturing systems. According to two different production targets, mini flow time and JIT, the detailed solutions and operation process were given. At last with the example of a gear workshop, a set of software was developed to calculate scheduling solution rapidly based on PGA.
