The production planner of a company forecasts the sales over the next four months as 3000, 1200, 1800, and 800 units, respectively. During a 50-day period when there were 30 workers, the company produced 18000 units. Assume that the numbers of workdays over the four months are 22, 24, 20, and 16, respectively. There are currently 10 workers employed, and there is no beginning inventory. The unit costs are given as follows: Inventory holding cost is 0.30 TL per unit per month; hiring cost is 120 TL per worker; and firing cost is 200 TL per worker. The planner solves the mathematical model of this problem. The optimal solution gives the following results, where Hi Number of workers hired in period t, F: Number of workers fired in period t HE HE Hs HA F F F F2 5.68 1.36 0 0 0 0 0 By rounding the values of the hires up and fires down, what is the total cost (in TL) of the resulting plan? 02178 b. 2144 2216 3.0 2267
