Ahmadreza Marandi: Robust Spare Parts Inventory Management 6 February 2025 16:00 - 17:00

In this seminar, Ahmadreza Marandi will give a talk about Robust Spare Parts Inventory Management.

We focus on the spare parts inventory control under demand uncertainty, particularly during the New Product Introduction (NPI) phase when historical data is limited. Most conventional spare parts inventory control models assume demand follows a Poisson process with a known rate. However, the rate may not be known when limited data is available. We propose an adaptive robust optimization (ARO) approach to multi-item spare parts inventory control. We show how the ARO problem can be reformulated as a tractable deterministic integer programming problem. We develop an efficient algorithm to obtain near-optimal solutions for thousands of items. We demonstrate the practical value of our model through a case study at ASML, a leading semiconductor equipment supplier. The case study reveals that our model consistently achieves higher service levels at lower costs than the conventional stochastic optimization approach employed at ASML.
