Hi everybody,

Currently, I did model Surgery Scheduling for a week(from Monday to Friday) and have implemented this model. 

I want this model to solve for a year. If I only want to simulate 12 months, I should write myself a script so that it solves itself, again and again, reads the next instance of data again and again. That means, I want the program should solve it 12*4=48 times automatically.

Is there any example to schedule for the long term?

I would be very thankful for any advice.

best regards,

Sherzod

Which of CPLEX's many APIs did you use to implement the model?

Thank you very much for your answer.

I created a model for surgery scheduling with OPL. It schedules surgeries for one week. But I need to schedule for a longer period. I have to run this model for different data iteratively. And, if I run the model for data1, can I add remaining surgeries(unscheduled surgeries) from data1 to data2 in the next iteration?

What you have to do is to loop over the 48 weeks and create and solve a new model for each week (potentially using as input the results from the previous week).

In case you are using OPL, take a look for example at opl/examples/opl/mulprod/mulprod_main.mod (ignore the stuff related to bases/warm starts) or opl/examples/opl/LagrangianRelaxation/LagrangianRelaxation.mod
