OPM 502: Supply Chain Analytics: Inventory Management

Inventory management is a core element of any company’s supply chain management activities. Yet, deciding on the right amount of inventory, in a given setting, is a challenging task. For many companies, inventory ties up a huge amount of capital. To set appropriate inventory levels, companies must trade off inventory costs and benefits. While inventory costs tend to be readily visible, measuring inventory benefits is more demanding, in general. Business analytics tools and techniques are of great value to master these challenges. This course introduces such approaches. It structures the analysis by distinguishing different inventory drivers. For each driver, it first highlights the underlying economic trade-offs and then introduces and analyses quantitative models that allow to optimize them. Core topics include demand forecasting, lot sizing, safety stocks, and seasonal inventory. The course also addresses the interplay between the sales and operations functions of a firm.
