CBRS: Continuous Benchmark Rate Setting. Business problem: how are the different metrics/ technologies/ operating models/ layout impacting the productivity? Output of the project: develop a model which defines Site-specific Benchmark Rates based on Site’s characteristics. This document will describe (from initial shaping to final deployment) a new methodology for benchmarking AMZL sites’ performance in terms of costs and productivity. The IB CBRS model, Continuous Benchmark Rate Setting model for Inbound, will introduce a quarterly-refreshed benchmark rate for the Inbound core processes in AMZL Delivery Stations (Last Mile Logistics sites). This model is built upon the K-means clustering approach, and it is based on Stations’ layout peculiarities, available technologies, existing processes, and seasonality.
