Research Interests

Srinivasan’s research focuses on production-inventory optimization problems. Multi-period capacitated production inventory problems are numerically challenging and computationally intensive. These problems have been researched extensively, and various approximations to solve them have been proposed. In this thesis, unlike classic inventory models, we use a concave, monotonically non-decreasing clearing function (CF) for replenishment. Clearing functions are meta-models that capture the queuing behavior and relationship between the workload and the production in the capacitated production system. Despite various stochastic approximation methods available in the literature, they are not tested against an exact benchmark solution, which prevents rigorous assessment of the quality of their solutions relative to optimality. To gain initial insight, we start by considering the single-period version of the problem, where all production from the period can be used to meet the current period’s demand; hence a single-period lead time zero model. Since the single-period problem is the building block for the multi-period problem, we then develop an exact solution for the multiple-period problem using a stochastic dynamic programming method to obtain a benchmark for all approximation methods to illustrate the optimality gap and quality of the policy.
