Mary is the manager of the Alpha company in the grocery industry. The major role of Alpha company is working as a grocery distributor though the company also produces some products. There are 4 products W, X, Y, and Z caused a lot of troubles for Mary in the past several years since the inventory and sales records were not available. From 2021 with the investment of IT and supply chain infrastructure, Mary can continuously monitor the sales and inventory information of these 4 products. It was the end of 2021. Mary had collected all 2021 weekly sales data and order history for these 4 products shown in the attached spreadsheet. This file also includes the historical order information for every weeks order in 2021. Mary wanted to use scientific ways to forecast demand and manage inventory for these 4 products. She decided to assign a project to Jason who has worked in the company for several years and just got his MBA degree from UNC Pembroke last year. Consider yourself as Jason to figure out what to do from this point forward. 1. Mary hoped Jason can determine which forecast methods will be appropriate for each of these 4 products. Moreover, Jason should provide the demand forecast for the first 4 weeks of 2022 for each of these 4 products so Mary can test Jasons method at the beginning of 2022.
