The most recent optimization algorithm for (s, S) order policies with continuous demand was developed byFedergruen and Zipkin (1985). This was also the first efficient algorithm, which uses policy iteration instead ofdiscretization. Zheng and Federgruen (1991) developed an even more efficient...

This paper extends a fundamental result about single-item inventory systems. This approachallows more general performance measures, demand processes and order policies, and leads toeasier analysis and implementation, than prior research. We obtain closed form expressions forthe Laplace...
