摘要：To clarify the impact of demand variability on single item stochastic inventory systems with setup costs, we subsume the distributional information of the lead time demand into its mean and variance and solve the resulting problem against the worst possible distribution in this class. For (Q, r) policies we obtain in closed form a distribution-free solution for Q and r, and upper bounds on the optimal long run average cost and on the optimal batch size. As a byproduct we develop a robust, dist...

摘要：This paper is concerned with the problem of resource allocation and target setting in the provision of public services. The paper develops a network-based representation of multilevel resource management With equity, efficiency, and effectiveness being recognised as the fundamental objectives of the system. On the modelling side, the proposed method combines data envelopment analysis and goal programming formulations integrated within an interactive planning framework. An illustrative applicat...
