In an evaluation of labor assignment rules when workers are not perfectly interchangeable, Paul. M. Bobrowski and Paul Sungchil Park created a dynamic job shop with 9 work centers and 9 workers, both numbered 1–9. The efficiency of each worker is specified in the following labor efficiency matrix, which represents the degree of worker cross-training.† Work Centers     1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85   0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 0.95 0.95 0.95 0.95 0.95 0.85 0.85 0.85 0.85 1.00 W o r k e r s (a) For what work center(s) is worker 2 least efficient?

A new surgical facility called Cut & Sew has opened in the United States. The branches of the facility are spread throughout the country. These are job shops that handle a variety of outpatient surgical procedures. The process of the facility is set up in a way that one doctor will cut and another will sew. The data regarding the patients and the estimated time for cutting and sewing for each patient are given in the following table: Patient A Cut Time (hours) 2.3 2.5 Sew Time (hours) 2.8 3.0 1.5 1.0 2.8 IB 2.0 0.6 3.8 If we apply the following sequence B-C-D-A-E, the makespan is place).
