Could I please get an explanation on identifying decision variables, objective functions and constraints in detail. Thanks

Use Solver to find the optimal solution to the given integer programming problem.

Consider the same operating room discussed in the Solver example in the chapter. Suppose that instead

of maximizing profit from surgeries, our objective is to minimize the cost incurred due to surgeries. As

before, we denote the number of major surgeries scheduled in a week using decision variable s1, the

number of minor surgeries scheduled in a week using decision variable s2, and the number of elective

surgeries scheduled in a week using decision variable s3.

The relevant data for each type of surgery is:

Surgery Type Cost Operating Room Time Labor Hours

Major (s1) $5,500 4 hours 15

Minor (s2) $3,000 0.5 hour 10

Elective (s3) $4,000 2 hours 12

In addition, for this problem we will assume the facility has only one operating room, which is available

60 hours per week, and the facility has a total of 500 labor hours a week that can be devoted to

surgeries.

Prior to using Solver, you may want to formulate your problem (i.e, clearly identify decision variables,

objective functions and constraints)
