13 A sheet metal shop was in moving to a new facility and wanted to create a layout for their new factory. The new building was 60 feet by 20 feet. The operations manager had looked into dif- ferent methods for developing a layout and decided to try Systematic Layout Planning (SLP). He has worked with the project team to put together the information given below.

a Construct the initial relationship diagram based on the information given above and table C in exhibit TN6.9.

b. Use the answer in part a to create an initial layout for the sheet metal shop assuming all departments are of equal size.

c. Create a final layout by adjusting your answer in part b to account for square footage and building size.1+++ 14 Francis Johnson's plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 15 units per hour and there is room for only four workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task.

a. Draw the precedence diagram.

b. What is the workstation cycle time?

c. Balance the line so that only four workstations are required. Use whatever method you feel is appropriate.

d. What is the efficiency of your line balance?
