This paper concerns a multilocation newsboy problem with normal demand at each location and identical linear holding and penalty cost functions at each location. Consolidation of demand from several facilities is considered, and an expression is derived for the resulting expected holding and...

This paper considers an N period production planning problem in which a sequence of known demands d₁, d₂,..., d_N must be satisfied. The cost of production in period t consists of a setup cost K_t plus a marginal cost per unit c_t. The cost of carrying a unit of inventory into period t is h_{t - 1}....

We consider the problem of setting safety stock when both the demand in a period and the lead time are random variables. There are two cases to consider. In the first case the parameters of the demand and lead time distributions are known; in the second case they are unknown and must be...
