Consider a dynamic lot-size model with five periods. The demand, setup cost, and unit holding cost vary per period and are as shown in the table below. Period i Demand D, (units) Setup cost K, () 1 5 27 2 23 27 30 30 3 4 5 9964 10 Holding cost h, () 4 4 3 4 5 There is no initial inventory. The variable ordering cost is 1 for all periods. Determine the order quantities y, i = 1,...,5, and the corresponding total costs using the Silver- Meal heuristic. When calculating the total costs, the variable ordering costs should also be included.
