    Inventory-minded friends:

    I wanted to let you know about a Python package that I recently published for inventory optimization and simulation called 
    stockpyl. It implements classical single-node inventory models like the economic order quantity (EOQ), newsvendor, and Wagner-Whitin problems. It also contains algorithms for multi-echelon inventory optimization (MEIO) under both stochastic-service model (SSM) and guaranteed-service model (GSM) assumptions. And, it has extensive features for simulating multi-echelon inventory systems.

    The package is available on PyPI at (or you can install from the command line using pip install stockpyl). The source code is available on GitHub at, and documentation is at Feedback welcome!
