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 … determining the optimal s. Furthermore, we constructtwo aid functions (generated by the optimality conditions for s and S) , and …

We … obtain closed form expressions forthe Laplace transforms of the expressions of the performance measures, and with the help of … anefficient inversion algorithm, the approximations of these cost and service measures are almost upto machine precision. …

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small … for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand … repeat the success of revenue management in practice if reference price effects are included in the demand model and the …
