We introduce a single location periodic review inventory control problem with lost sales and fractional lead times. We model the optimal inventory control problem as a stochastic dynamic program and analyze properties of the objective function as well as the optimal policy. We present upper and lower bounds on the optimal policy. These bounds can readily be used in easily computable heuristics....

The present paper is an attempt to develop a new heuristic algorithm, find the optimal sequence to minimize the utilization time of the machines and hence their rental cost for two stage specially structured flow shop scheduling under specified rental policy in which processing times and set up time are associated with their respective probabilities including transportation time. Further jo...
In this paper, we explore the issue of coordination in a manufacturer-retailer supply chain where the manufacturer is socially responsible and invests in CSR activities. On the other hand, the retailer invests in promotional efforts and uses a periodic review order-up-to policy for replenishing items. First, the decentralized decision-making structure is modeled to calculate the minimum accepta...
