Planners for a company are about to prepare the aggregate plan in 2021. They have collected the following information about demand for their products: Month Jan Feb Mac Apr May Jun Forecast 400 510 400 405 460 675 Month Jul Aug Sep Oct Nov Dec Forecast 580 600 300 280 440 500 The company has 24 employees, each of whom can produce 28 units per month. An employee added to or subtracted from the workforce affects the production rate by 20 units per month. Regular production cost = RM33 per unit Overtime cost = RM 6 per unit Inventory holding cost = RM 10 per unit per period (based on average inventory) Back orders cost = RM 50 per unit per period Hiring and training costs = RM100 per employee Layoff costs = RM200 per employee Required: a) Assume that the initial inventory is zero. Formulate and evaluate the costs of three plans. You may use a worksheet (eg. Excel) to set up this problem. 1) a level production plan ii) a chase production plan iil) an intermediate plan (consider a level strategy, using inventory to absorb the uneven demand but allowing some backlog. Overtime at a maximum rate of 48 units per month could be used as needed. You need to describe the plan in your answer) b) Explain which plan you would choose, and provide two advantages and any negative impacts it might have.
