Question 1-....-Points (3): 1. Define discrete event simulation modeling in your own words. When do we usually implement this technique? 2. State two advantages and disadvantages of simulation modeling respectively. 3. What are the necessary steps involved in the discrete event simulation modeling process? You can use a flowchart to answer this question. 4. Pick a real-life system that you are interested to study using discrete event simulation modeling. Provide the following about the system: 4.1. The objective of your study (discuss what you want to know/measure about the system) 4.2. Entities involved and their attributes 4.3. Resources and activities 4.4. Events involved (for i.e. Arrival, departure, starting and closing time of the system) Note: Please use your own words for answering the above question. For questions (1-3), you just need to write 3-4 lines. The answer to question 4 will not be graded. I just want to know your problem formulation intuition
