One of two new software products solving optimal inventorycontrol problems for trade and tech service enterprises. The solutions provided by these products decrease drastically the inventory costs and increase profitability by choosing optimal timing and sizes of replenishments. DOSE-TRADE can solve problems with compound Poisson demand for continuous-review case as well as for periodic and random opportunities for replenishments . This approach is more adequate and gives (as simulation experiments with real-life data show) much better solutions. In addition to usual two-level control policies DOSE-TRADE can find optimal policies with fixed case size. It always uses exact methods and finds global optimum in acceptable time. It has a built-in simulation block which allows quantitative efficiency comparison of your existing inventory control system with DOSE.
