Question

A Missouri job shop has four departments––machining (M), dipping in a chemical bath (D), finishing (f), and plating (P) ––assigned to four areas. The operations manager, Mary Marrs, has gathered the following data for this job shop as it is currently laid out (Plan A).
100s of Work pieces Moved Between Work Areas Each Year


Distances Between Work Areas (Departments) in Feet

(a) Determine cost of the current layout, Plan A, from the data above.
(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:
