Since the traditional mass production can no longer adapt to the rapid changes of the modern markets, customized production has been adopted by more and more manufacturing enterprises. As a result, theories of customized production have become a research focus for many researchers. On the basis of the already-made theoretic researches into customization, this dissertation makes a systematic study of order acceptance in the context of customization, proposes a system structure of prompt response in order acceptance(OA), and focuses on three key technical issues in order acceptance, namely risk analysis and evaluation, how to make quotations promptly and reasonably to the customers, and how to lower costs in sample development.The dissertation describes the definition,features, flow of work, technical support and development tendency of made-to-order (MTO) manufacturing. While describing the present researches into non-mass-customization, the paper analyzes the limitations of mass customization (MC), which is a major strategy in dealing with MTO manufacturig, in real practice, and the importance of order acceptance in MTO manufacturing. Then it probes into the underlying causes of failure in order acceptance, proposes a framework system of prompt response in order acceptance in the context of customization production, and the countermeasures to improve the speed and success rate of order acceptance.The dissertation introduces risk management into the process of MTO manufacturing, elaborates the risk factors in MTO manufacturing, makes a qualitative study of the rule of risk changes in MTO, and then moves on to a mathematical model of risk loss, which can be used to calculate the risk level of different stages or of the whole process of MTO manufacturing by fuzzy mathematics,Analytic Hierarchy Process (AHP) and Analytic Network Process(ANP) . A case is also cited to exemplify how to apply the evaluation method.The paper then discusses the great significance of quotation in MTO and the difficulties it encounters, analyzes various quotation methods widely used at home and abroad and their shortcomings. After a careful study of the designing and process planning of quotation, the author proposes a prompt quotation method based on the output value per unit time, and sets up a mathematical model of quotation.Since the trial-manufacture and development of samples is the process of no directly ecomonic benefit and high rejection rate, this dissertation suggests a process planning method which aims at the lowest rejection loss, and sets up a mathematical model of process planning. In optimized decision-making of multi-procedure process planning, adaptive genetic algorithm is employed to search for the optimum results. An example is given to prove how to reduce the rejection loss using the method.Combining the reality of the enterprise in which the author carries out his research and using integrated thoughtway of CIMS, the paper develops a system of prompt response in order acceptance of customization production, and describes how this system work in enterprises and the results of applying this sytem.
