Problem 1: Figure (1) gives the activity relationship and areas of eight departments. Develop a layout using the SLP technique. Problem 2: The ABC Cooling and Heating Company manufactures several different types of air conditioners. Five departments are involved in the processing required for the products. A summary of the processing sequences required for the five major products and the weekly production volumes for the products are shown in the tables below along with the department area. Based on the graph-based construction method, develop a block layout. Problem 3: Consider four departments labeled A, B, C, and D. Each department is represented by a 11 square. The following data are given 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 11 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.)
