Info

Developing a Modeling Approach • Define submodels, modules, data structures, control logic • Appropriate level of detail — judgment call • Often multiple ways to model, represent logic • This model: – Separate Arrive modules for two part types – Separate Server modules for each Prep area – Inspect modules for Sealer and Rework – Depart modules for Shipping, Salvage, Scrap – Transfer times: Route – Attribute Sealer Time assigned at Arrival (parts have different times at the Sealer station) Simulation with Arena — Chapter 5 — Modeling Basic Operations and Inputs 5 - 8
Stations • Up to now: no (zero) transfer times between stations — realistic • Station: Physical location for an activity (or a group of activities) • Way to model entity flow, transfer generally • Provide animation “launching, landing pads” • Each Station has a unique name • Station marker: • Can separate logical station, physical station Simulation with Arena — Chapter 5 — Modeling Basic Operations and Inputs 5 - 9
