The anticipated demand for a certain item over the next 6 months is 175, 125, 160, 100, 115, and 140. Current inventory of this item is 30, and ending inventory should be 40. Assume a holding cost of $1 per month per unit and a setup cost of $140. Based on Silver-Meal heuristic: y=[a],[b].[c].[d].[e].[f] with total cost = $[g] Based on Least Unit Cost heuristic: y=[h], [i], [j], [k], [I], [m] with total cost $[n] Based on Part Period Balancing: y=[0].[p] [q] [r][t]. [u] with total cost $[v]
