1. (30 POINTS) Suppose that you need to design the layout for a manufacturing facility which produces various components for airplanes. The number and type of components to be manufactured change all the time. a) What is the appropriate layout design for this facility? Name it and give the reasons for your selection. b) Suppose that there are various machines in this facility, and the average number of loads that are carried between these machines vary according to the following from-to matrix: Weld Drill Mill Grind Paint Lathe X 0 X Lathe Weld Drill Mill 50 100 X 80 0 80 X 0 60 0 Grind Paint 90 30 X 50 40 80 30 X If you have the following areas for locating these machines, how would you place these five machines in order to minimize the total distances that the loads travel? Find by trial-and-error. area 1 10 m area 2 10 m area 3 10 m area 4 10 m area 5 10 m area 6 c) Suppose that the facility needs to develop a work cell in order to produce a certain airplane wing component. The necessary activities to produce this item are given in the following work balance chart (the operation times are in seconds): WORK BALANCE CHART 140 120 120 100 80 75 80 60 60 45 40 20 20 0 drill weld grind paint assemble test If one needs to produce 180 components every day (in a total of 8-hour production time), how many workers should be assigned to this work cell in order to complete the required amount of production? How should these workers be trained
