Exercise 2: Consider four departments labeled A, B, C, and D. Each department is represented by a 1 X 1 square. The following data are given: Flow-Between Matrix Unit Cost Matrix A B C D A B C D A - 6 0 3. A - 2 0 3 Initial Layout B 0 B 2 - 1 0 A B C 0 C 0 1 0 C D D D 3 0 0 The location of department A is fixed. Answer the following questions using CRAFT with two-way exchanges only. a. List all the department pairs that CRAFT would consider exchanging. (Do not compute their associated cost.) b. Compute the actual cost of exchanging departments C and D. c. Given that department A is fixed and that each department must remain as a 1 X 1 square, is the layout obtained by exchanging departments C and D optimum? Why or why not? (Hint: Examine the properties of the resulting layout and consider the objective function of CRAFT.) Exercise 1: XYZ Inc. has a facility with six departments (A, B, C, D, E, and F). A summary of the processing sequence for 10 products and the weekly production forecasts for the products are given in the tables below. a. Develop the from-to chart based on the expected weekly production. b. Develop a block layout using SLP.
