Manual: Malaria Seasonality and Calculating Resupply

This concept paper describes an approach for enhancing the simple average monthly consumption (AMC) rule to handle seasonal commodities, while maintaining some of its simplicity to continue to meet complex needs of the developing country settings where it would be used. The approach operationally involves multiplying the AMC by indices that compensate for seasonality — referred to as Look-Ahead Seasonality Indices (LSI) — before multiplying by the maximum stock level. The LSI approach is tested through three case studies, in Burkina Faso, Zambia, and Zimbabwe.
