STUDENT LAB/TUTORIAL ACTIVITY REPORT
Course Code : CSM 233
Course Name : Computer Simulation & modeling
EXPERIMENT/EXERCISE NO. : 05
TITLE OF EXPERIMENT/EXERCISE: Multi Processing System Simulation Model
Goal AIM/OBJECTIVE (similar to the manual):
Description :
In this session we will cover:
1. The Arena simulation software environment.
2. Simulation project concepts such as Entities, Resources, Queues, Attributes, Variables, and Statistical accumulators in Arena.
3.Flowchartand data modules in Arena
4. The Create, Process, and Dispose modules in Arena.
5. Building and running a simple simulation model discuss the results of a simulation run.
Objectives:
A quick tour of the Arena environment
• Recap of basic concepts
• The three (3) basic modules
• Building your first model
• Before you run the model
• Running the model
• Viewing the results
CASE STUDY/ RELEVANT PROGRAMS / DESIGN/CONFIGURATION / IMPLEMENTATION/COMMANDS. (A PART TEACHER TAUGHT IN THE
LAB)
Theory / Explanation:
Consider the following system. Create an Arena model.
a) Problem statement as stated here
Problem Statement :
Funny parts called AB arrive to a section of our system and go through different stations for some processes then leave the system. Interarrvial time is distributed as expo(5 hr). The process at Station 1requires 1 worker take expo(4 hr). The process at Station 2 requires 1 doctor and 2 nurse and it will take expo(5 hr). The process Station 3 requires 1 bed and it will take expo(13 hr). The process at Station 4 requires 3 of tool X and 2 of will take expo(10 hr). The process at Station 5 requires 2 carts and it will take expo(5 hr). We have one of one of Station 2, 3 identical Station 3, 3 parallel Station 4, and one of Station 5. Simulate for 10,000 hrs
b) Draw logical model using software (past it into your Word file)
c) Copy of statistical output (past it into your Word file)
