ABC Co. is to plan its workforce and production levels for next year. Forecast demands for the next 4 quarters are 1160,960, 1150,1380 units. Ending inventory of last year is expected to be 60, and the ABC would like to have a minimum of 50 units in inventory at the end of next year. The cost of holding one unit in inventory for one quarter is $190. There are currently 200 workers. The cost of hiring one worker is $700, and the cost of firing one worker is $1500. In the past, the plant manager observed that over 60 working days and with the workforce level constant at 200 workers, ABC produced 1200 units. The number of working days for the next 4 quarters are respectively 61, 62, 65, and 58. Assume that ABC plans to adopt a level strategy constant workforce plan) for next year. (a) (10 pts) Determine the level of workforce for next year such that all quarterly demands will be met. How many workers does ABC need to hire or fire at the beginning of next year? Hire 9 workers Hire 2 workers Fire 6 workers Fire 11 wokers 2. Same as Problem 1. except that the forecast demands for the next 4 quarters are 1160, 1260,1150.980 units.
