Multiple Choice

Table J.17
A company must take on seven new projects. Each project has a planning stage and a design stage, and the planning stage must be completed before the design stage can begin. Also, two project teams are available to work on these projects: Team 1 works only on planning stages of projects, and Team 2 works only on design stages of projects. The times to complete the project stage, in days, are shown in the following table.

-Using the information in Table J.17 and Johnson's rule, develop a schedule that minimizes makespan for these seven jobs. Assume that job C could be neatly split into two equal parts, each having half of the processing time on each machine as the full job C. Using your original sequence, but splitting job C, what is the makespan for the seven jobs?

• A) between 58 and 59 days
• B) between 56 and 57 days
• C) between 55 and 56 days
• D) between 57 and 58 days

Back Pressure

Resistance against the flow of fluids in piping or engineering systems, often necessary for the proper functioning of certain mechanisms.
