question 4

Essay

A new surgical facility called Cut & Sew is opening in neighborhoods throughout the United States. They are job shops that handle a variety of outpatient surgical procedures. Their process is set up so that one doctor cuts and the other sews. They have five patients to sequence for tomorrow. Since the weather forecast is for a cool and sunny day, they would also like to play golf tomorrow. They want to sequence their patients with the objective of minimizing the time from the beginning of the first job until the finish of that job. The patients and estimated times are as follows:
$$\begin{array} { c c c } \text { Patent } & \text { Cut Time hours) } & \text { Sew Time hours) } \\\text { A } & 2.3 & 2.8 \\\text { B } & 2.5 & 3.0 \\\text { C } & 2.0 & 1.5 \\\text { D } & 0.6 & 1.0 \\\text { E } & 3.6 & 2.6\end{array}$$
Sequence the patients using Johnson's Method, state the schedule for each operation, and determine the minimum makespan.
