Salient Simulation Model Features FEATURE DETAILS (Manual Page Numbers) ENTITY ARRIVALS Continuous (159); Periodic (164); Patterned (160); Scheduled (165) ACTIVITY Represents Details of a Step (145-150) ROUTES Percentage (186); Alternate (170); Conditional (176); Create (I72); Attach (178); Detach (180); Pickup (188); Renege (180) VARIABLES Can be used to assess a situation and make decisions dynamically. Can be affected by any Entity. For example crowd between two points in a process. (256) ATTRIBUTES Can be used to represent entity-specific properties. The value of the property stays with the Entity. For example, a Patient could be a Trauma Patient or Simple Patient. (254) RESOURCES and SHIFT Represent human and equipment resources. (153, 155) RESOURCE ASSIGNMENT Different ways of using a Resource: GET, FREE, GET AND FREE, ALTERNATE (193) STORAGE Waiting areas. Useful to direct flow out of. (201) ACTION LOGIC Custom Logic of Processing at a Step. (215) FUNCTIONS Specific Keywords with inbuilt calculations. E.g. CLOCK(). (212) SIMULATION OPTIONS Options of how we want to run the simulation (duration, warm up time, run time, replications). (271) DETAILED OUTPUT Provides all output for throughput, cycle time, queues,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
