The requirements problem with pricing flexibility generalizes the standard economic lot-sizing problem by recognizing that the demand for a good can often be influenced by adjusting its price level. This naturally leads to a profit maximization model that integrates price setting as well as production and inventory management. In this paper, we consider the NP-hard problem that arises in the presence of general cost functions as well as time-varying production capacities. We study a reformulation of the problem as an economic lot-sizing problem and use this reformulation to derive running times for dynamic programming and approximation algorithms for the requirements planning problem.
