Each product requires a certain number of different types of components (C1, C2, … C5) to be assembled. Figure 1 shows the products and their respective components Components C1 to C5 are fed to the production line according to exponential distributions with prameters 50, 45, 52, 80, and 49 (all in minutes) respectively. Assembling times are given by TRIA (10,12,15) for A, TRIA (37,48,55) for B and TRIA (18, 20, 22) for C. The plant layout consists of 5 stations, Stations 1 through 4 are machining stations and each component has a separate processing sequence through these stations. Operation times at each machine are shown in table 1. After various machining process, all components go to the fifth station which is the assembly station. Components are put together according to product type. At each of the machine stations, the highest priority is given to the longest components that have been in the system Station 5 has two assembly robots that may be selected at random, but one has failure problems. It breaks down periodically and historical data on these breakdowns have shown a mean uptime of exponential, λ=120 minutes. The time to repair also follows an exponential distribution with a mean of 4 minutes. The system operates 8 hours shift in a day. Transfer between each two stations is TRIA (7,8,10) minutes. Due to increase in demand, and the need to reduce production costs, the company is considering ways to effectively reduce work in process and reduce throughput times whilst maintaining a good level of resource utilisation. To achieve this, management wants to identify the bottleneck processes and increase their capacities if necessary. As a systems analyst consulted by this company, 1. Develop a simulation model with appropriate animations of the production system. You may use the system layout in figure 2 for your animation. 2. Identify the bottleneck process and propose alternative system improvement initiatives that will improve the performance factors listed. Model your proposed system and compare results for resource utilisation, work-in-process, throughput times and number out of each product type with the original system 3. Discuss your improvements with reference to the original system in a written report to the management of the company. The report should present a strong case for your proposal and clearly show the values of the performance factors before and after your improvement (you may want to use Arena’s output analyser for your comparative studies). Validate the results using statistical means (see lecture notes 5 and associated references). 4. In addition, the company is considering installation of a conveyor system to transfer entities between stations. You are required to simulate the conveyor system (non-accumulating) and find the best settings (e.g. velocity) that retains the appropriate resource utilisation but could reduce overall time entities remain in the system. Distances between stations are. Use run conditions defined as: Warm-up Period =30 minutes, replication length = 5 days and number of replication =10. The system requires initialisation between replications. Decide on whether to initialise statistics at Run replications and explain your reasoning why you have made the decision.
