Manufacture
Can be very useful in designing and optimizing the number and arrangement of the test stands for the best results.
Manufacture
Worldwide Clients
Important logic issues that are addressed in reality using Programmable Logic Controllers (PLC) can be tested using simulation to save valuable time and expense during actual implementation.

Apply in Healt-care
Health-care
Healthcare
When modeling a health care clinic is the capacity of simulation to model complex patient flows through health care clinics, and then to play `what if' games by changing the patient flow rules and policies.
Healthcare
Healthcare
By altering patient routing and flow, it may be possible to minimize patient waiting time and increase staff utilization rates.
Healthcare
Conclusion
Design and evaluation of new manufacturing processes.
Performance improvement of existing manufacturing processes, for example, feasibility study of an automated material handling system.
Conclusion
Establishment of optimum operational policies, for example, studying how many
Cards should be introduced on production shop floor in order to reduce work-in-progress.
An algorithm (or engine) to support production planning and scheduling.
