Homework Answers
Answer: Safety stock should be 125 units
Explanation:
| demand per period, d | 543 | |
| Lead time, LT (in periods) | 2.0 | |
| standard deviation of period demand, Sd | 38.0 | |
| standard deviation of lead time, SLT | 0.00 | |
| Standard deviation of lead time demand, SdLT | SQRT((LT*(Sd)^2) + (d*SLT)^2)) | 53.74 |
| Service level desired | 99.0% | |
| Z value at service level, z | NORMSINV(service probability) | 2.33 |
| Safety stock, SS | z*SdLT | 125 |

Bass-killer, a special plastic bait, is available at the Winona Fishing Cabin(WFC) at $10 per bag. The demand can be approximated by a normal distribution with a mean of 21 bags per week and a standard deviation of 3.4 bags per week. Lead time is 3 weeks, and there will be shipping cost $50 for each order. The new manager desires a chance of stockout of 5% or lower, and estimates the annual inventory holding cost is 20% of sales...

A company begins a review of ordering policies for its continuous review system by checking the current policies for a sample of SKUs. Following are the characteristics of one item: follows≻Demand (D) = 80 units/week (Assume 50 weeks per year) follows≻Ordering and setup cost (S) =90/order follows≻Holding cost (H) =18/unit/year follows≻Lead time (L) = 22 week(s) follows≻Standard deviation of weekly demand = 2020 units follows≻Cycle-service level = 9292 percent follows≻EOQ = 200200 units Using the above information, develop the best...

Your firm uses a periodic review system for all SKUs classified, using ABC analysis, as B or C items. Further, it uses a continuous review system for all SKUs classified as A items. The demand for a specific SKU, currently classified as an A item, has been dropping. You have been asked to evaluate the impact of moving the item from continuous review to periodic review. Assume your firm operates 52 weeks per year,...
