Question 6

Given the following chart of jobs assigned with Johnson's rule,suppose that all the jobs (A,B,C,etc)could be evenly divided into two tasks (such as A1 and A2,B1 and B2,etc).Suppose job D is split into two equivalently sized sections,D1 and D2,each with a body work time of 1.5 hours and a paint time of 2 hours (D1 and D2 sum to 3 hours of body work and 4 hours of paint which is equivalent to
D).How much is makespan reduced by this splitting of D?

Accepted Answer

Job D1 could now start paint at t=1.5 an
