The monthly inventory cost is calculated based on the final inventory for the month. A safety stock of 10% of your forecast is absolutely essential (inventory final). Fido 12% 22:41 a) Develop a synchronous production strategy that respects the forecasts and the safety stock of each month, by varying only the level of manpower by contracts with variable duration. Calculate the total cost of your synchronous plan. N.B. to calculate the number of employees required for the monthly production, you must absolutely round your result to the nearest whole value. This means that if you need 16.4 employees for your monthly production, you hire 17 employees for production for 16.4 employees. You pay for 17 employees and 0.6 employees will not be used, but will be paid anyway. b) Compare costs to a leveled production plan that uses inventory and sub-contracting to absorb fluctuations. Calculate the cost of your plan. N.B. since the employees work every day of the year, the quantity to be produced each month will vary from month to month. For example, the month of February has 28 days while that of January has 31. Therefore, you must use a leveled production per day to calculate the production by month. In the examples presented in the course notes, it is assumed that the employees work the same number of days per month, and therefore produce the same quantity per month. N.B.
