A Study on Inventory Policy of Mining Relationships among Inventory Items

本研究考察了库存物品的真实状态和处理方式，它们之间可能存在着一定的关系。然后考虑涉及这些关系的库存策略。(1)为进一步的研究建立了原始数据库；(2)利用支持度-置信度框架，提出了库存物品分类的新概念。通过新算法和对比实验，验证了该算法的实用性和有效性。(3)对发生销售损失时的成本进行了估算。提出了基于新成本函数的部分和完全缺货模型。(4)研究了其他库存控制和生产计划问题，特别是多层批量问题。这项研究发表了大量的期刊论文。

This study investigates real states and treatments of inventory items among them there may are relationships. Then inventory policies involving these relationships are considered. Following contributions are achieved in our researches:(1) Set up original data bases for our further researches(2) By using the framework of support-confidence, new concept of classification of inventory items is developed. New algorithm and comparison experiment had been made to show the utility and performance of our algorithm(3) We also estimated the cost when lost sales are occurred. Several models including partial and complete backorder based on the new cost function are presented.(4) Other inventory control and production planning problem, especially on multilevel lot sizing problem are investigated. A lot of journal papers are presented on the research.
