how to set up one shop to make maximum profit

Problem description

The daily operating cost of each machine is $1000 and the wage of each operator is $3000 per week. The machine can operate 8 hours a day and five days a week.
A customer has to pay $100 to get the service. Also, the inter-arrival time follows the statistical distribution exponential(0, 60, getstream(current)).
The service time of each customer in a machine follows the statistical distribution lognormal2(30, 3.1, 0.5, getstream(current)). Also, the operator has to set up the machine before each service. The setup time of the machine follows the statistical distribution uniform(25, 40, getstream(current)). If a customer waits more than 200 seconds, they will leave.
Try to set up one shop to make maximum profit.
Build a simulation model. How much is the profit that you can make in a week based on your model? What are the utilizations of the operator and the machine in your model? How many customers do you serve? How many customers leave?

Hi @Stephanie,

It looks like this question may be part of a homework assignment or academic project. The professors who assign simulation modeling exercises using FlexSim expect that the academic integrity of their assignments will be maintained. In addition, we are supportive of Honor Codes or Pledges that regulate the behavior surrounding academic assignments.

I recommend reading our best practices page on the subject, which includes some resources that you should find helpful as you use FlexSim for academic purposes. I also highly recommend Dr. Allen Greenwood's FlexSim Primer, which was written specifically for students and professors.
