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 prompt any adverse feelings from 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 January 560 February 760 March 860 April 560 May 360 June 320 July 160 August 160 September 260 October 660 November 760 December 860 Manufacturing cost is $160 per server, equally divided between materials and labor. Inventory storage cost is $5 per month. A shortage of servers 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 160 units. Ten labor hours are required per DVD player. The workday is eight hours. Develop an aggregate production schedule for the year using a constant workforce. For simplicity, assume 22 working days each month except July, when the plant closes down for three weeks' vacation (leaving seven working days). Assume that total production capacity is greater than or equal to total demand (i.e., compute workforce level based on annual demand and annual capacity). using this format JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC total Forecast 560 760 860 560 360 320 160 160 260 660 760 860 6,280 beginning inventory available production ending inventory costs lost sales inventory total
