Essay

A firm of six departments has the following trip matrix and current block plan of all departments: $$\begin{array}{l}\begin{array} { | l | c | c | c | c | c | c | } \hline \begin{array} { c } \text { Dept } \\\text { Name }\end{array} & \text { A } & \text { B } & \text { C } & \text { D } & \text { E } & \text { F } \\\hline \text { A } & - & 7 & 8 & 9 & 0 & 2 \\\hline B & & - & 6 & 3 & 0 & 10 \\\hline C & & & - & 2 & 12 & 0 \\\hline D & & & & - & 3 & 0 \\\hline \text { E } & & & & & - & 6 \\\hline \text { A } & & & & & & - \\\hline\end{array}\\\begin{array} { | l | l | l | } \hline \mathrm { A } & \mathrm { B } & \mathrm { C } \\\hline \mathrm { D } & \mathrm { E } & \mathrm { F } \\\hline\end{array}\end{array}$$
a. What is the load- distance score for the current layout? (Assume rectilinear distance and that the distance between departments A and B is one unit of distance.)
b. What would be the load- distance score for the following layout? $$\begin{array} { | l | l | l | } \hline A & C & E \\\hline \mathrm { D } & \mathrm { B } & \mathrm { F } \\\hline\end{array}$$
