Prior research has investigated the appropriate ordering policy for an inventory system. Two key factors to are daily demand and lead time. Many studies assume lead time and daily demand are independent. In this study, we relax this assumption for a continuous review inventory system and analyze...

In this paper, we apply continuous review (S-1, S) policy for inventory control in a three-echelon supply chain (SC) including r identical retailers, a central warehouse with limited storage space, and two independent manufacturing plants which offer two kinds of product to the customer. The...

Lead time is one of the major limits that affect planning at every stage of the supply chain system. In this paper, we study a continuous review inventory model. This paper investigates the ordering cost reductions are dependent on lead time. This study addressed two-echelon supply chain problem...

This paper describes about two strategies in consignment inventory based supply chain with controllable lead time and delaying last delivery comprising a two level supply chain involving single vendor and multi buyers. This model would give minimum joint total expected cost of the strategies...

In this article, an imperfect vendor-buyer inventory system with stochastic demand, process quality control and learning in production is investigated. It is assumed that there are learning in production and investment for process quality improvement at the vendor’s end, and lot-size dependent...

This paper provides an approximation for the customer service level for a perishable item in a stochastic lost sales environment using a periodic review inventory control system in which demand is discrete and case pack sizes are fixed. We first show that the customer service level is virtually...

Purpose: The purpose of this study is to investigate how ambiguity faced by the risk-neutral manager affects the firm’s optimal level of safety stock. Design/methodology/approach: This study adopts the traditional model of Arrow et al. (1951) and employ a manager who has multiple prior beliefs...
