a)

Summary Introduction

To determine: The processing sequence required to minimize the time.

Introduction: Johnson’s rule helps to determine the processing sequence that would minimize the overall time of the process. It would schedule the jobs in two work centers and it would determine the optimal sequence.

b)

Summary Introduction

To construct: The chart of the resulting sequence to determine the idle time.
