QUESTION II. The three-period demand values and production-related costs for a product are given in the table below. Demand and production quantities are integer values. For this product, for which there is no stock at the beginning of the planning period, it is not allowed to meet the demands later. At the end of the third period, it is required to have 1 unit of stock. Table. Demand and cost information The cost functions of the product are as follows. Using the wagner-whitin algorithm for the threeperiod dynamic production planning problem for this product, find the quantities and stock levels that must be produced in each period. ft(Xt,It+)={At+ctXt+htIt+,htIt+,Xt>0Xt=0ht(It+)={It+,5+5It+,0It+5It+>5 Discuss how the calculations of the wagner-whitin algorithm will change, choosing only one of the following situations. a) If there is a production capacity b) If cost of selling is added c) If it has multiple products
