Referencing Styles : OSCOLA Title: Assignment 2: Modelling and Simulation with ExtendSim Description: This is a group assignment involving the design and simulation of a system using the techniques and tools of the unit content. Criteria for assessment: Assignment work in the unit is fully described, along with the assessment criteria, on the assignment page of the Moodle-based unit web site. A peer assessment form is also completed by all students to ensure fair distribution of marks. Guidelines on undertaking a group assignment such as conducting meetings and recording processes will be given to students. Complete an ExtendSim model for the problem. Write a report to management to summarise your findings from the different models that you have built. Your report should include the following: 1. Analysis of the standard performance measures (i.e. queue length, waiting time in queue, the average cycle time and server utilisation) for the different models. 2. A discussion on the following questions: i. Identify what is the effect of the additional variability in Model 2 compared to the results in Model 1? ii. Are there any differences in system performance of Model 3 compared to the results in Model 2? iii. Besides the standard performance measures, analyse the performance of Model 4 using the following additional measures:  The time spent shopping (average and standard deviation).  The number of customers (average and standard deviation).  The separate cycle times for heavy and light shoppers (average and standard deviation). iv. How does the design change in Model 5 affect the cycle times for the two customer groups and for the average customer? 3. Recommendation(s) to management based on the results generated.
