  1. Simulation featuring ARENA By: Chad Eskew Middleware Spring 2007

  2. ARENA • Discrete event simulator • Dr. Dennis Pegden in 1982, SIMAN • Still run old models on current version • 2 level design: flow logic and control data • Works in tandem with Excel and Visio • Works well when timing is involved • Is used to better assembly lines/supply chain environments

  3. ARENA Pricing • The current version of ARENA being currently shipped is ARENA 11.0 • It must be purchased on a university purchase order and licensed to a professor • The current textbook can be purchased through McGraw-Hill and textbook includes the academic version which has limitations • ARENA can only be used for research purposes only • For a single ARENA PE Educational copy it is $1,850 or for a 20 Seat-License it is $3,000 • The animation software is an additional $650, single, or $2,750 for the 20 Seat-License

  4. Reader Agent Model in ARENA • The Arrival/Source comes from either a input from a file or one generated by data • Queue is where the entity waits for a free server • Server is where a delay happens or where a process is supposed to take place • Departure is where the entity exits the model

  5. Results • ARENA is a powerful software simulation product. • It is too reliant on timing for it to be of any use in the hospital inventory location problem. • It is my thought that one could solve the problem using Java to create a GUI that can use 2-D mapping and sections to code a program such that it searches through tag reads and finds the last read for each item based on a day-by-day basis that is maintained over long periods of time. • What should be left for the next day is a list of all current inventory items, with unique IDs for each item, and its last known read/location. This can then be used to map the hospital using floor plans.

  6. How ARENA Relates to TagCentric • ARENA relates to TagCentric through the spreadsheet data gathered by a reader. • The output that ARENA creates can then be used to evaluate a given process and that subsequent data can be used to determine how one can improve on the current process. • Data can then be reread and enter and then reevaluated by the ARENA software many times until a desired conclusion is the result.

  7. Future Work • SDC/Capstone or Middleware, year long • Simulation class offered by the Industrial Engineering department and taught by Dr. Rossetti. • Book Recommends: ProModel, Witness, AutoMod, and Flexsim • SourceForge Recommends: OMNeT++, SimPy Simulation Package, Fungus Agent Simulator, and SimTool
