Description

Provides a comprehensive and practical treatment of all the important aspects of a simulation study, including modeling, simulation software, model verification and validation, input modeling, random number generators, generating random variates, statistical design and the analysis of a simulation study

### Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Describe the fundamentals of simulation and the techniques for developing simulation models.

2.

Use simulation as a decision support tool.

3.

Translate a business problem into a simulation model.

4.

Formulate an appropriate and correct discrete event simulation model of a system at an appropriate level of detail.

5.

Use an Excel spreadsheet with add-ins, e.g. @Risk, to build simulation models.

6.

Use SIMUL8 to model and solve a simulation problem.

7.

Identify the best probability distribution to describe the outcomes of a random variable.

8.

Generate random variates for discrete and continuous distributions.

9.

Analyse and interpret the results of a simulation model for making a business decision.

### Teaching and Learning Strategies

Real world examples, case studies and published peer reviewed papers will be utilised, where possible.

### Module Assessment Strategies

Continuous Assessment

1.    Project work - Design and analyse ones own Simulation                   20%.

Final Examination

1.    One written 2.5 hour paper                                                            40%

2.    One computer based 2.5 hour exam involving @Risk & Simul8          40%
