Question
Chapter 11, Problem 50AP
Summary Introduction
Interpretation: An initial layout for four departments and from-to charts giving distances separating departments and unit transportation costs appear in Figure 11 -33. Using the CRAFT pairwise exchange technique, the layout recommended to minimize the total material handling costs needs to be determined.
Figure 11 - 33
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.

A Missouri job shop bas four departments- machining (M), dipping in a chemical bath (D), finishing (F), and plating (P)-assigned to four work areas. The operations manager, MaryMarrs, bas gathered the following data for this job shop as it is currently laid out (Plan A). It costs $0.50 to move workpiece foot in the job shop.Marrs's goal is to find a layout that bas the lowest materialhandlingcost.a) Detemline cost of the current layout, Plan A, from the given data.b) One alternative is to switch those departments with the high loads, namely, finishing (F) and plating (P), which alters the distance between them and machining (M) and dipping (D), as follows: What is the cost of this layout?Marrs now wants you to evaluate Plan C, which also switches milling (M) and dri lling (D), below.…
