Homework 5 - IEM 4203 This homework is for practice only. It will not be collected or graded. I may reuse some of these problems on the final exam, so I will not be providing a solution key (@ 1. What is the major design tradeoff encountered in warehouse/storage design? 2. Name an advantage and a disadvantage for a random storage policy and for a dedicated storage policy. When might one be preferred over the other? 3. What is honeycomb loss? What is cube utilization? 4. When might the following S/R cycles be preferred: single command, dual command, and multiple command? 5. Differentiate between discrete picking, zone picking, and batch picking. What are some advantages/disadvantages of each? Under what circumstances might each be used? 6. Anticipated warehouse inventory (#pallets) over the next 12 months is given in the table below. How many slots would be needed under: a) a randomized storage policy? b) a dedicated storage policy? c) a class-based storage policy (you pick the classes, intelligently)?

Be able to write and understand integer programs relating to location, allocation, and location-allocation problems (e.g., ambulance set cover problem, transportation problem, capacitated facility location problem). 8. A regional telephone is attempting to determine the optimal location for a training facility for its operators. The operators are located in four operations centers and the training facility is to serve these centers. The coordinates of the four centers and the number of operations working in each are given in the table below. Assuming the rectilinear metric is the most appropriate distance measure, determine the optimal coordinates of the training facility. Which method are you using and why did you choose it? Coordinates Town F Number of Operators (ooos) Center #1 32 58 6.8 Center #2 49 42 4.3 Center #3 11 69 6.0 Center #4 31 3.4
