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:

Using Johnson's sequencing rule, the final sequence of the patients is

a$.2-5-3-1-4$
