How To Optimize Storage Classes In A Unit-Load Warehouse, Marcus Ang, Yun Fong Lim Oct 2019

How To Optimize Storage Classes In A Unit-Load Warehouse, Marcus Ang, Yun Fong Lim

Research Collection Lee Kong Chian School Of Business

We study a problem of optimizing storage classes in a unit-load warehouse such that the total travel cost is minimized. This is crucial to the operational efficiency of unit-load warehouses, which constitute a crit- ical part of a supply chain. We propose a novel approach called the FB method to solve the problem. The FB method is suitable for general receiving-dock and shipping-dock locations that may not coincide. The FB method first ranks the locations according to the frequencies that they are visited, which are estimated by a linear program based on the warehouse’s layout as well as the products’ …

Interim Brigade Combat Team (Ibct) Munitions Distribution Study, Todd S. Bertulis Mar 2002

Interim Brigade Combat Team (Ibct) Munitions Distribution Study, Todd S. Bertulis

Theses and Dissertations

This research sought to describe an alternative way for calculating expected back order (EBO) for reparable inventory systems. The high costs associated with reparable items management, together with its importance for system's availability, make the assessment of back orders of great importance in supporting decisions of what-to-buy and where-to-locate those items. Starting at the point that existing models (METRIC, MOD-METRIC, and VARIMETRIC) rely on some assumptions that often cannot be met in real life, the proposed method (called P-METRIC), which is a mix of simulation and mathematical analytical model, relaxes assumptions about Demand, Time to Repair (TTR), and Ordering & …
