Research And Application On The Flexible Production Planning For Order

In violent market competition, the enterprise management turned "sale by production" to "production by sale". Especially individuation and diversification of customers requirements have made Made To Order(MTO) one of important means for production in manufacturing industry. According to customer order requirement, it is an important program in MTO how production planning(PP) is realized for quick response. Based on the analysis of the relative theory and technologies of PP, this dissertation presents production planning knowledge(PPK) and establishment of PPK base, and then presents the flexible PP realization based on PPK in MTO, and further, discusses dynamic coherence of PP on the order variation,. The dissertation research was applied in cooperative company.In the first chapter, the background, significance and the current research status of PP are firstly introduced, and then key research contents and architecture of this dissertation are briefly described.In the second chapter, by analysis of relative experiences on PP, PPK is introduced, it present definition, content and presentation of PPK. And then PPK base is created, organization of PPK, architecture of PPK base and reasoning applications of PP are elucidated.In the third chapter, the whole application frame of PPK-oriented flexible PP in MTO is put forward, the task process of main production schedule(MPS), material requirement planning(MRP) and shop floor planning(SFP) are presented. By application of PPK, MPS, MRP and SFP creation algorithms are expounded. So it makes production planning more flexibility.In the forth chapter, the conventional PP treatment methods of order variation is analyzed, then PP variation model on order variation is presented according to order variation characteristics and types, three PP variation treatment algorithms for order variation are elucidated pertinently. And dynamic coherence of order-oriented flexible production planning is realized.In the fifth chapter, according to theory research and informationizing requirement of enterprises, a flexible PP management application system for order-oriented is developed and these applications instances of order-oriented PP modules and shop floor planning modules are mainly presented with the developed project in the dissertation.In the end, this dissertation summarizes the research work and gives the future work of this research.
