2. The operations manager of an assembly and paint shop has five trucks to schedule for repair. He would like to minimize the throughput time (makespan) to complete all work on these cars. Each truck requires assembly prior to painting. The estimates of the times required to do the assembly and paint work on each are as follows:Use Johnson's rule to sequence these five jobs for minimum total duration. Show your step by step work in determining the job sequence and calculate the total duration of finishing assembly and painting operations on all the five trucks ?
