What To Do Next Each project group is identified by project number and group (1-1, 1-2, 2-1, 2-2, etc.) Each project group is identified by project number and group (1-1, 1-2, 2-1, 2-2, etc.) Each group is formed by 2 members as shown on the previous slide. Select your group members and a project leader (Form a team) Each group is formed by 2 members as shown on the previous slide. Select your group members and a project leader (Form a team) Project leader should send me an containing the project group name, group members and the task for each group member – see the next slide (Until 9’th November 2007) Project leader should send me an containing the project group name, group members and the task for each group member – see the next slide (Until 9’th November 2007)

Basic Activities of the Project Collect data Develop and implement the model Production runs Write the report Task for the group: identify the tasks and assign the tasks for each group member

Collect Data This activity is the most important of all Study the system to find out the activities and collect data by observing the system at different times (at least two different time periods). Collect both input and output data for validation purposes Try to fit the raw data to a known distribution (such as exponential, uniform, etc.)

Develop and Implement the Model Design and implement the model using the SIMDL DOS version. Design and implement the model using the SIMDL DOS version. Validate and verify the model using the data collected from observations Validate and verify the model using the data collected from observations Run the model with distributions closest to your collected data if you could not fit your raw data to a probability distribution function. For example, you may use an exponential distribution for interarrival and service times as a good choice Run the model with distributions closest to your collected data if you could not fit your raw data to a probability distribution function. For example, you may use an exponential distribution for interarrival and service times as a good choice

Production Runs Design at least two experiments to test the model's responsiveness to parameter changes Design at least two experiments to test the model's responsiveness to parameter changes For example, if the model develops a queue with large waiting times, the experiment could be the change in server numbers to see the effect of this parameter change in waiting times. For example, if the model develops a queue with large waiting times, the experiment could be the change in server numbers to see the effect of this parameter change in waiting times.

Feedback If your model does not work properly or contains design/implementation errors you will be asked to correct it. In this case you will get a lower grade. If your model does not work properly or contains design/implementation errors you will be asked to correct it. In this case you will get a lower grade. I will return my feedbacks individually I will return my feedbacks individually

Next You will be asked to implement the same model using GPSS as your next task You will be asked to implement the same model using GPSS as your next task Do not forget that the deadline for the GPSS report is 12’th December 2007 Do not forget that the deadline for the GPSS report is 12’th December 2007
