The most cost-effective option. Introduction: Mean time between failures (MTBF): The mean time between failures is a term which denotes the time that is elapsed between the first failure of a product and the second failure of a product. It is calculated during the normal system operation. Mean time to repair (MTTR): The mean time to repair is the time incurred for a device to fail and also the time elapsed to repair the device. The repair is carried out after the failure of the device.

The S&OP team at Kansas Furniture, led by David Angelow, has received estimates of demand requirements as shown in the table. Assuming one-time stockout costs for lost sales of $125 per unit, inventory carrying costs of $30 per unit per month, and zero beginning and ending inventory, evaluate the following plan on an incremental cost basis: Plan B: Vary the workforce to produce the prior month's demand. Demand was 1,300 units in June. The cost of hiring additional workers is $35 per unit produced. The cost of layoffs is $60 per unit cut back. (Enter all responses as whole numbers.) Note: Both hiring and layoff costs are incurred in the month of the change (i.e., going from production of 1,300 in July to 1300 in August requires a layoff (and related costs) of 0 units in August). Hire Month 1 July Demand 1300 Production (Units) Layoff (Units) Ending Inventory Stockouts (Units) 2 August 1150 3 September 1100 4 October 1600 5 November 1900 6 December 1900

The S&OP team at Kansas Furniture, led by David Angelow, has received estimates of demand requirements as shown in the table. Assuming one-time stockout costs for lost sales of $100 per unit, inventory carrying costs of $20 per unit per month, and zero beginning and ending inventory, evaluate the following plan on an incremental cost basis: Plan A: Produce at a steady rate (equal to minimum requirements) of 1,100 units per month and subcontract additional units at a $65 per unit premium cost. Subcontracting capacity is limited to 800 units per month. (Enter all responses as whole numbers).
