Hello I am trying to create some logic for a bigger simulation i am trying to do.
1. The processing time of product A on machines 1, 3 and 4 are uniform(25,35), uniform(100,120) and uniform(30,35). The processing time of product B on machines 2, 3 and 4 are uniform(20,30), uniform(100,130) and uniform(20,35). The processing time of product C on machines 1, 2, 3 and 4 are uniform(30,45), uniform(25,40), uniform(120,150) and uniform(30,35). The inter-arrival times of products A, B and C are uniform(25,35), uniform(30,40) and uniform(40,45). There is a setup time of uniform(10,20) before the first product of the same type is processed. Besides, the setup task needs an operator to perform. The walking speed of an operator is 0.5m/s.
2. Products arrive in batches. Also, the number of each batch is between 20-30. The types of products have to be different in consecutive batches.
3. Machine 3 processes products in batches. The number of each batch is 30.
4. Except for machine 3, the others process products one by one.
5. The distance between machine 3 and machine 4 is about 20 meters. Products have to be transported by a forklift or a conveyor. The speed of a forklift is 1m/s and that of conveyor is 1m/s as well. However, a forklift needs an operator to transport products in batches of 10 and the loading/unloading is 10s/5s. There is no loading/unloading for a conveyor.
Iam stucking in step 3. Can you help me with step 3? If possible, you can check if my 5 steps are correct because I see a lot of inventory in Queue.
