Unformatted text preview: 1 IE 306.01 PS #5 20.03.2009 Simulation Example: Consider the following continously operating job shop. Interarrival times are distributed as follows: Interarrival time (hours) Probability 0 0.23 1 0.37 2 0.28 3 0.12 Processing times for jobs are normally distributed with mean 50 minutes and standard deviation 8 minutes. Construct a simulation table, and perform a simulation for 10 new customers. Assume that simulation begins there is one job being processed (scheduled to be completed in 25 minutes) and there is one job with a 50-minute processing time in the queue. (a) What was the average time in the queue? (b) What was the maximum time in the system? (c) What was the total idle time of the server? Random numbers for interarrival times: 0.557, 0.174, 0.864, 0.674, 0.904, 0.263, 0.485, 0.513, 0.086, 0.437 Random processing times: 54, 56, 51, 59, 45, 44, 46, 52, 47, 48 1. A production process manufactures alternators for outboard engines used in recreational boating. On the average,1 % of the alternators will not perform up to the required standards...
