1.0 INTRODUCTION

The aim of this report is to examine the existing business model that is in operation in S&J garage, an understanding of what the inputs and outputs that are required for the smooth running of the business and a weekly activity that mimics the real life situation of the company will be presented.

The software that will be used to carry this out is called ARENA; it is a software that has been developed based on the principle of flow-oriented simulation. It allows for the modeling of real life scenarios and modifications can be made in order to test and an opportunity is given to experiment with what we normally cannot do with the original business because of the cost implication. This is a very great way of increasing overall efficiency of any business.

A table will be drawn to illustrate the entities, state variables and events. A flowchart diagram would also be used to show a representation of the overall process flow. An activity cycle diagram will also be created, this will identify the key processes and the resources that are assigned to them; it will also show what the sequence of activities is like during the process and how the resources’ states change (“idle” to “busy” and vice versa) when an event occurs. What these diagrams will do is to further assist in understanding the situation at S&J.

When the model is complete, what the current resource utilization, bottlenecks, costs incurred and revenue received are is analyzed according to what the real life situation is. Afterwards, amendments will be made to some parts of the model to ascertain if an improvement in its efficiency can be changed. Some of the improvements to be made include: Minimizing the overall service time

Achieving a minimum queue at each work Centre.
Maximizing the resource(s) utilizations.
Minimizing average car waiting time in the overall process.
If all of the above can be achieved it will lead to reduction of costs which are associated with the business operations. Finally, future directions and recommendations will be suggested as regards what can be done to what they have at the moment to increase overall efficiency of the company and ultimately its profitability.

1.1 AIM

The aim of this simulation exercise is to minimize the overall simulation time, achieve a minimum queue at each work center, maximize the resource(s) utilizations and minimize average waiting time. 1.2 OBJECTIVES

The objectives of this simulation include:
* To use ARENA software to model the real life business scenario of S&J garage. * To create an understanding with the aid of a table, an activity cycle diagram and a flow chart diagram of the core entities and processes carried out with in the business model. * To analyze the utilization of resources and the bottlenecks present in the current system. * To create scenarios, which modify and increase the productivity of the current business model. * To choose the best scenario that gives the best efficiency of the business model. * To suggest further directions, recommendations and suggestions that could give the garage a better competitive edge over their rivals.

1.3 ASSUMPTIONS

To effectively model this, the following assumptions will be applied: 1) An 8:00am-5:00pm...
