Shoney Video Concepts produces a line of video streaming servers that are linked to computers for storing movies. These devices have very fast access and large storage capacity. Shoney is trying to determine a production plan for the next 12 months. The main criterion for this plan is that the employment level is to be held constant over the period. Shoney is continuing in its R&D efforts to develop new applications and prefers not to cause any adverse feelings with the local workforce. For the same reason, all employees should put in full workweeks, even if that is not the lowest-cost alternative. The forecast for the next 12 months is MONTH FORECAST DEMAND     MONTH FORECAST DEMAND
January 600      July 200
February 800     August 200
March 900      September 300
April 600      October 700
May 400     November 800
June 300     December 900

Manufacturing cost is $200 per set, equally divided between materials and labor. Inventory storage cost is $5 per month. A shortage of sets results in lost sales and is estimated to cost an overall $20 per unit short. The inventory on hand at the beginning of the planning period is 200 units. Ten labor hours are required per videodisc player. The workday is eight hours.
