YD plant's production system consists of 10 stations, and produces two products (A type & B type) simultaneously. Number of each station and its capacity is shown below, and each product does not have to go through every station.

Through simulation, verify the Little's Law for both best case and case with changes for the production system. 1. Record TH, WIP, and CT for the entire system, and verify the Little's Law. 2. Record TH, WIP, and CT for each product and verify the Little's Law. 3. Record TH, WIP, and CT for one specific station, and verify the Little's Law. The production system of the YD plant consists of 10 stations, and each product is produced through different routes as shown in the <Figure 1>. We will collect the TH, WIP, CT values of each product and for each station. Simulation will run for 1000 minutes, and for the system stability and accuracy of the statistic values, we will have 100 minutes of warm-up time. Experiment 1. Record TH, WIP, and CT for the entire production system and verify t he Little's Law for the best case and case with changes. - Changes for M/C 5 and M/C 6 are considered simultaneously (Case 1: Type A→ 6min/job, Type B → 4min/job) (Case 2: Type A → 9min/job, Type B → 3min/job) 1 2 Bes t ca # se Fluc tuat ed Best cas Fluctuate d Best cas e d Fluctuate e A Type B Type A Type Experiment 2.
