Question
Chapter 11, Problem 51AP
Summary Introduction
Interpretation: An initial layout of five departments and a from-to flow data chart are given in Figure 11-34. Assuming that departments A and D are in fixed locations and cannot be moved, and also that the objective is to minimize the total distance traveled, then the layout recommended by CRAFT for departments B, C and E needs to be given.
Figure 11 - 34
Concept Introduction: The full form of CRAFT is Computerized Relative Allocation of Facilities Technique and it uses a pair wise exchange algorithm for calculating the optimal results and this tool is used to enhance the existing facilities for a layout.

Mason Machine Tools is reevaluating its facility layout. Thecurrent layout is shown in Figure 10-13 and the from–to matrixis in Table 10-11. Mason has to leave department C in its currentlocation because relocation costs are too high. It is consideringexchanging departments B and D. Evaluate the proposal bycomputing the ld score for both layouts.
The next step is to select a basic layout that depicts the general form and arrangement of operations facility. Identify and describe the most suitablebasic layout for the jean manufacturing facility. Justify your choice
Hren Electronics is in process of setting a new office building. The following tables show the number of expected communications among the four departments and two possible layouts for considerations (tables 2 and 3 show the distance among the departments in the given layout). Calculate a total cost (or total distance traveled) for each layout and provide a recommendation that would minimize the total costs.
