Luxury Boats Manufacturing - System Modeling and Simulation Assessment Answers

Internal Code: 2ACAG

System Modeling and Simulation Assignment

Exercise questions: The production process of a luxury boats manufacturing consists of 4 stations. Body Paint is the first station; the yachts are sprayed with high quality paint and then they are transferred to the Assembly station. After assembly go to the Trim shop followed by inspection. The products failing inspection move to the Rework station, the ones that are passed are moved to a temporary storage where they wait to be transferred. Part 1:

1. Using Arena (enclose your CD or memory sticks), simulate the system for a whole year (no initialisation of stats or system).
2. What is the total number of boats made of each type at the end of the year? What is the number of Reworks by type of boat?
3. What is the average time for a customer to receive their order by type?
4. What is the utilisation of each resource at each station?
5. What is the average queue time behind each station?
6. What is the average WIP of each type (including production and transport time)?
7. Identify the bottleneck of the system if any exists and explain why you think that they are bottlenecks of the system.
8. How long do boats wait in the temporary storage to be transported?
9. What is the average distance that each ship travels a year? 10- What is the average fuel consumption for each ship?

Part 2: The sales and management of the company believes that they could accept further number of orders (possibly 8 to 12 boats a month). What are the ramifications on the current system? Answer the following:

1. What will be the average increase in the time of delivery to customers?
2. Using the entity Balking technique behind the stations and transporters find out how many of those orders cannot be met if the company wishes to maintain the same delivery lead- time (hint: you need to make comparison between the new model and the answer to question 2)?
3. Identify the bottlenecks for the new situation and suggest methods (e.g. changes in capacity,

Part 3: The management is on a drive to reduce its carbon emissions for their distribution systems. In order to do so the need a much smarter way of utilising their transporters (the Ships) and minimising the distance they travel. Advise the management with possible solutions to reduce carbon footprint of the transport systems (reduction in fuel consumption?
