Research On Operator Optimization Configuration Of Intermittent Manufacturing Plant

Due to the different production characteristics of two production systems, we solve theoperator assignment problem of discrete manufacturers in two stages: one is the long termoperator staff level planning for a productionline in pipelined （Flow-shop） manufacturingplants,which concerned with ‘‘who works where?”; and the other is the short termassignment of operators in workshop-type（Job-shop）flexible manufacturing plants basedoncustomer individuality demand,which concerned with ‘‘who works when?”.This paper takes the average operation time and the quality of the completed products ina given period as the evaluation indexes, the weights of which is determined by entropyvalue method, and build operator competence evaluation model to calculate the personnelcompetency index. Based on the personnel competency index, the matching degree of theoperators and the stations is calculated by establishing evaluation model, on the basis ofwhich the operator optimization allocation model for the Flow-shop manufacturing plants isbuilt, the optimization goal of which is to maximize the sum of matching degree andminimize the matching degree of difference between station of the production line, and themodel is solved by a heuristic algorithm and is verified by an real example. For the flexibleJob-shop manufacturing plants, the resource-constraint mathematical model is constructedbased on personnel competency index. The initial solution of the model is obtained byheuristic algorithm, and the optimal personnel scheduling plan is obtained with theminimum duration by using the revised genetic algorithm to solve the model and thefeasibility and practicability of the model is verified by real cases. Finally, the model andmethod in this paper was applied in a heavy-duty automobile companyaccording to thespecific need of the assembly line producing main reducers drive axles, and the conceptmodel, function model and database model of system are constructed and a MES-orientedassembly line operators scheduling system is developed.
