INTRODUCTION TO MODELING AND SIMULATION

INTRODUCTION TO MODELING AND SIMULATION

1. WHAT IS MODELING?

   • Representation of the construction and working of some system of interest
     • Purpose:Predicts changes of a system

2. WHAT IS SIMULATION?

   • Operation of the model. It can also be studiede and how the properties infer inside the system
     • Purpose:Reduces chances of failure and optimizes its system
   • STEPS FOR A DEVELOPING SIMULATION MODEL:
     • 1. IDENTIFY THE PROBLEM
       • 2.FORMULATE THE PROBLEM
         • 3.COLLECT AND PROCESS DATA
           • 4.FORMULATE AND DEVELOP A MODEL
             • 5.VALIDATE THE MODEL
               • 6.DOCUMENT THE MODEL
                 • 7.SELECT APPROPIATE DESIGN
                   • 8.ESTABLISH EXPERIMENTAL CONDITIONS
   • ADVANTAGES AND DISADVANTAGES
     • ADVANTAGES
       • Better understanding of a system
         • Study the effects of an environment
           • Experiment with new or unknown situations
     • DISADVANTAGES
       • Erroneous assumptions
         • Poor schedule and budget planning
           • Inappropiate analytic solution

3. WHEN TO USE?

   • To observe certain process from the real world. Math models when analytic solutions are impossible
