Simulation with Arena, 3 rd ed. Chapter 8 – Entity Transfer Slide 3 of 25 Types of Entity Transfers So Far Connect Zero-delay Connection graphic vs. module Labels (no graphic) Route Non-zero-delay — constant, r.v., expression Stations, animated Routes Fixed routes vs. entity-dependent Sequences Connect and Route both assume: No limit on number in transit at a time Entities have their own feet

Simulation with Arena, 3 rd ed. Chapter 8 – Entity Transfer Slide 4 of 25 New Types of Entity Transfers Resource-constrained transfers Limit total number of entities in transit at a time Entities still have their own feet Telecommunications (number of packets), logistics (number of vehicles) Material-handling devices Transporters – fork lifts, trucks, carts, wheelchairs Usually place limits on numbers, capabilities of transporters Like a Resource, except moveable Conveyors Belts, hook lines, escalators Usually limit space on conveyor, speed Non-accumulating vs. accumulating

Simulation with Arena, 3 rd ed. Chapter 8 – Entity Transfer Slide 5 of 25 Model 8-1: Small Manufacturing System with Resource-Constrained Transfers Original system (Model 7-1) Assumed all transfer times = 2 minutes … keep (for now) Parts have their own feet … keep (for now) No limit on number of parts in transit at a time … dump Now – no more than 2 parts can be in motion at a given time If other parts are ready to go, they must wait until there’s room to go Model via existing constructs think creatively Model “space” on the “road” as a Resource Limit the number of Units of this Resource Entity must Seize unit of “space” resource before beginning trip, Release it at end of trip

Simulation with Arena, 3 rd ed. Chapter 8 – Entity Transfer Slide 6 of 25 Two Ways to Model Resource- Constrained Transfers Both use a new Transfer Resource representing space on the transitways Capacity set to 2 in Resource data module Maybe the most obvious way (but won’t do) … Before each Route module insert a Seize module to Seize one unit of Transfer (queue, priority details … see text) After each Station module (except Order Release ) insert a Release module to free up one unit of Transfer

    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.
