BioMarin currently uses an inventory planning system based on initiating production of specific end items in order to ensure that forecast inventory levels never fall below a required minimum. This system is currently managed manually. In this project, we first develop a tool that automates this planning based on exogenously determined minimum inventory levels. Once this tool has been validated, we will use it as a key component in the development of algorithms to optimize these minimum inventory levels.
This project consists of two key steps:

1) Develop a spreadsheet based tool to automate inventory planning based on minimum forecast inventory levels in end-product inventory.

2) Optimize those minimum levels to ensure that demand is met while mimimizing inventory holding cost and expired inventory.
