* NOTE Example E2.1: If you are running example 7-1 (Course Book, Mousavi) using Arena's academic/demo version you realise that a warning/error will pop up after a while declaring that "you have exceeded 150 entities" allowed for the academic/demo version of Arena . This is due to the fact that the model is generating too many entities i.e. exceeding the allowance for the demo version. The reason for this error could be due to the parts waiting behind resources to be processed or too many entities being generated. Do not worry - by changing the time between arrivals or reducing the processing time you can solve this problem at this stage. Later on you will be using the Balking example to monitor the number of entities behind queues and will be able to troubleshoot this sort of problem.

[This was intentional for you to experience this sort of error in Arena]

However, your individual assignments are designed in a way that you should not have this issue at all. Therefore, if you encounter this error whilst completing your individual assignment; this means that there is a mistake in your model. You need to detect and resolve this mistake in your modelling approach.

Sample of an Excellent Assignment submission by a group in 2015. It is a very good template for you to follow. Even though it is a group assignment, but the format and overall coverage of the material can also be used for individual assignments.
