Integration of job shop scheduling with discrete event simulation for manufacturing facilities

A system for integrating job shop scheduling with discrete event simulation for manufacturing facilities, comprising:

• a scheduler module operable to provide a job schedule for a facility;
• a simulator module operable to simulate discrete events of a facility using the job schedule generated by the scheduler, the simulator simulating the facility based on one or more local rules, one or more resources, and one or more parameters associated with said locals rules and said resources, the simulator further modeling said one or more parameters as random variables and using said random variables in its simulation of the facility,
• an analysis module operable to provide a feedback to said scheduler based on output from the simulator, said feedback including at least an instruction to the scheduler to include at least one of said one or more resource and to change said one or more parameters based on said modeling of said one or more parameters as random variables, said feedback for the scheduler to use for updating a scheduling model associated with said scheduler and generating an updated schedule.
