摘要: A standard inventory model is examined with a concave increasing ordering cost function rather than simply linear one setup cost. generalized s, S policy shown to be optimal in the n-period problem. generalization of k-convex and quasi-convex functions quasi-k-convex required process. The probability densities demand must one-sided Polya densities.
