Quality office designs created an aggregate production plan using a level strategy. The planning period is 12 months and the product is a certain fixture. The table on the following page presents the aggregate production plan. There is no inventory to begin with. The initial staffing level was at 11 employees before the given plan was created. The labor required to make one unit is 1.2 hours. For the production planning period, they found that they had a total of 253 workdays and needed to produce a total of 21,320 products. Thus they figured that they needed to make 21,320/253 = 84.26 or 85 units per day. As one units needs 1.2 hours, they needed a total of 85*1.2 = 102 labor hours each day. Given that one employee would work 8 hours per day, they figured that they thus need 102/8 = 12.75 or 13 employees at a level production schedule. Labor is paid $1500/month. Hiring costs are $475 per employee. Inventory costs are assessed on "Average Inventory" and are $12/unit/time period. The plan they came up with is given in the table below.
