Arena: Assembly Line and Model
Production line
-Report-
In this report will be analysed the current production line of a manufacturing company that produces three different products. Because the system is consuming too much resources and it’s not very efficiently, ways to improve all this factors is needed. By identifying the bottleneck an alternative solution can be proposed for this problem. Due to increases of demand, and the need to reduce production costs, the company is considering ways of effectively reducing Work-in-Process and also reducing throughput times whilst maintaining a good level of resources utilization. For analysing the production line, a simulation model was built using Arena software program, based on information provided by company. The purpose of using Arena simulation software is to help demonstrate, predict, and measure system strategies for effective, efficient and optimized performance. The model was built using the following input data:
For manufacturing three different products (P1,P2,P3) the company uses five components (C1,C2,C3,C4,C5) .For assembling one product, three components are used following the next scheme:
Product 1 | C1 | C2 | C3 | Product 2 | C1 | C3 | C5 | Product 3 | C2 | C4 | C5 |
The components arrive according to an exponential distribution with the following parameters: C1 | C2 | C3 | C4 | C5 | 15 min | 10 min | 12 min | 8 min | 17 min |
In the process of fabricating this product all components need to follow a specific sequence to be processed and ready for final stage (assembly).
Stations 1 through 4 are machining stations and each component has a separate processing route and time through these stations and the 5-th station is the assembling station. Components routing and process times (all times are in minutes and are triangularly distributed).
Components | Station | Station | Station | Station | Station | C1 | 1 (5,15,20) | 2 (5,8,10) | 3 (15,20,25) | 4 (8,12,16) | 5 (assembly) | C2 | 1
