Outline of Final Research Achievements |
We investigate how to plan a inventory policy where items are considered to be correlated each other. Our contributions are,(1) We used association rules to describe the relationships of items, made a useful criterion by support-confidence framework and developed a calculation algorithm to evaluate the relationships between items. (2) Several criteria like as Max profit and Min loss are developed. Relationships with time windows are also considered. And substitution rules are discussed. (3) We estimated the cost when lost sales are occurred. (4) Several models including partial and complete backorder based on the new cost function are presented. the production scheduling problem considered the demand of items are associated in future and multilevel lot sizing problem are also discussed. Our research gives a fundamental inquiry on the assumption of independence of items. It is time to consider what should we do if the items are correlated because there are being in real world.
