Abstract

In Germany alone, inventories are estimated to be worth of more than 500 billion €. To manage these inventories, numerous inventory-control policies have been developed in the last decades. These inventory-control policies are typically derived analytically, which is often complicated and time consuming. For many relevant settings, such as complex multi-echelon models, there exist no closed-form formulae to describe the optimal solution. Optimal solutions for those problems are determined by complex algorithms that require several iteration steps. In this paper, we present an alternative approach to derive optimal or near-optimal inventory-control policies that are based on Genetic Programming (GP). GP is an algorithm related to Genetic Algorithms. It applies the principles of natural evolution to solve optimization problems. In this paper, we show how closed-form heuristics for a common inventory-control setting with periodic review can be found with GP. The advantage of GP is that inventory-control policies can be derived empirically without solving complex mathematical models.
