A warehouse serves 3 retail stores with a certain home cleaning product. The retail stores are called Fairview, Bristol, and Springfield (for the towns they are in). The lead time between any retail store and this warehouse is 4 working days. The lead time between the warehouse and the manufacturer is 10 working days. Daily demand for the working days in the past year is given in the Excel file for this question. Each row in the Excel file gives demand for that day. The data runs from day 1 to day 312 because the stores were only open for 312 working days in the calendar year.

The company uses a cycle service level (CSL) of 98% for this product.
