1. Using the data in case Exhibit 4 and the 2012 annual demand, calculate the EOQ and ROP quantities for the five SKUs scheduled to be produced in the last week of June. How do these amounts compare w... ith those calculated in 2011? Compare the increases in EOQs with the increases in annual demand. (2.5 points) 2. Brodie is uncertain if the costs presented in case Exhibit 2 are appropriate for determining the EOQs. What changes would you recommend, and why? Should the cost of the three idle part-time workers be included when the production line is down? Using the 2012 annual demand, and your recommendations, recalculate the EOQs for the five SKUs. (2.5 points) In set up costs, the cost of part time workers should also be included, as they are idle at that time. Assuming the salary of each part time worker to be half that of full time worker So, Total salary of 3 part time workers, during idle time of 1 hour = 3*0.5*23.5 = $35.25 So, new set up cost = $63.7 + $35.25 = $98.95 In carrying cost, storage cost was considered as 0%, which should be more because, there is always an opportunity cost of storing one inventory over another. So, considering storage cost as 2%, new carrying cost = 6% + 2% + 3% = 11% Some of the basic assumptions of EOQ are debated •The demand is not uniform throughout the year, which may lead to stock outs •The order of new batch takes time and is not done instantly. For this case, the ROP should be adjusted to include the lead time to place order [Show More]
