都市内物流に関するロジスティック費用と顧客サービスのトレードオフ

抄録

This paper makes an analytical and empirical study of distributing items by trucks from a supplier to many customers located in a surrounding region. The total logistic cost of a supplier and customers is formulated and minimized to determine the optimal time between dispatches. Customer service must be simultaneously considered for logistics management and its factors are represented by both average lead-time and the time between deliveries to each customer. The empirical analysis of trade-off between logistic cost and customer service implies that a supplier tries to gurantee higher level of customer service than that achieved by total cost minimization. This is a feature of Just-in-Time distribution strategies.
