INTEGRATED MANAGEMENT SYSTEM FOR PRODUCT DESIGN,PRODUCTION,INVENTORY AND DISTRIBUTION FUNCTIONS

该项目旨在开发一种创新的管理系统，有效地缩短从产品开发到产品推向市场的周期，并提高系统对市场用户需求变化的适应能力。结果，得到了以下结论：1.在对由工厂、库点和运输路径组成的配送网络进行建模和分析的基础上，提出了一种求解该问题的有效算法。通过对一些数值算例的应用，说明了该算法的有效性。提出了一种有效的生产订货系统，在该系统中可以控制混合缓冲系统，以减小库存、生产订货和配送订货水平的偏差。在融合概念的基础上，提出了用户需求评估中信息行为分析的基本模型和方法，以及产品/产品设计过程。模型和方法的一些应用表明了该模型和方法的有效性和存在的问题。

This project aims to develop aninnovative management system which is effective on the reduction of a lead time from product development to introducing the product into the market, and on increasing the adaptability of the system for changes of users' needs in a market. As aresult, the followings are obtained.1. Based on modeling of distribution network consisted of factory, stock-point and transporting route and analyzing the model, we developed an effective algorism to solve the problem. Application to some numerical examples clarifies the usefulness of the algorism proposed.2. An effective production ordering system is proposed, and in which mixed a buffer system can be controled to decrease the deviations of inventory, production ordering and distribution ordering levels.3. A basic model and method to analyze information behavior in users' needs assessment, and a product/production desigh process have been developed on the basis of the fusion concept. Some applications of the model and method clarify the usefulness and problems.
