Control Study About The Production Schedule On The Basis Of The Fuzzy Theory

Any making type enterprise, there must all be function planned and controlling, including the market requirement forecasting of the products, it already determines when to increase the equipment and personnel to make a plan, how it buy and can't make by supplies, how much there is, and so on .In the whole production management system, the production schedule is primary link, and a precondition carried out and controlled, its purpose is to stipulate goal and task of the activity in production for the time (plans) in the future, go on according to the request for the operations objective for the production work of guiding enterprises.This thesis is analyzed to the uncertain factor in every aspect of facing of enterprises in the decision-making process of the production schedule of the present stage mainly, put out better settlement countermeasure.This text part has introduced the relevant theory that is originally using in the article at first, it is the research of decision of the production schedule that has offered the theoretical foundation, then introduced the basic conception of the production schedule, and introduce the challenge that face in enterprise's development at the present stage, put forward the question at the same time, offer the theoretical foundation for argumentation for the future; Chapter four sum up the concept and position of the comprehensive production schedule briefly , discuss the comprehensive production schedule and fuzzy external characteristic that control, have put forward controlling the method thought fuzzily of comprehensive production schedule . And provide the comprehensive fuzzy general step of controlling the method of production schedule. Have analyzed the fuzzy set of interval value, then use it for in the comprehensive production schedule; Chapter five the theory summary of the main production schedule, what the main production schedule is directed against is not products group, but concrete products, is the final products based on independent demand. Controllingthe method fuzzily of main production schedule. Discuss the main fuzzy characteristic of production schedule and describe first, put forward controlling the method thought fuzzily of main production schedule. Adopt the balanced method piecemeal and strengthen the control of the production schedule. Chapter six the application in the production plans of production of fuzzy mathematics. Because of some methods at present being all the information based on accuracy the information in actual production is fuzzy, it is necessary to consider the fuzzy message of the production system. For this reason, provide the fuzzy method to the course of arranging in an order etc. in the production operation.This text applied the fuzzy theory to production through the instance finally, there is a series of limitation while using to avoid general much target planning, if can't reflect that restrain the condition from being up to the change of time, can't reflect and restrain a great deal of factors in the condition and influence a great deal of factors of the degree of order of importance and emergency of goal objectively, emphasized idealized " solving optimally " at the same time, and ignored" solving satisfied" with required practical problem.
