Simulation of Inventory System

April 17, 2008

A company that sells a single product would like to decide how many items it should have in inventory for each of the next n months (n is a fixed input parameter). The times between demands are IID exponential random variables with a mean of 0.1 month. The sizes of the demands,D, are IID random variables ……….

Job-Shop Model

April 15, 2008

Simlib to simulate a model of manufacturing system. This simulation illustrates how simulation can be used to identify bottlenecks in a production process. A manufacturing system consists of five work stations, and at present stations 1,2,…,5 consist of 3,2,4,3, and 1 identical machine(s), respectively. In effect, the system is a network of five multiserver queues. …………………………………………………

Multiteller Bank With Jockeying

April 15, 2008

Simlib to simulate a multiteller bank where the customers are allowed to jockey (move) from one queue to another if it seems to be to their advantage. A bank with five tellers opens its doors at 9 A.M. and closes its doors at 5 P.M., but operates until all customers in the bank by 5 P.M. have been served. Assume that the interarrival times of customers are IID exponential random variables with mean 1 minutes and that service times of customers are IID exponential random variables with mean 4.5 minutes…………….

Time-Shared Computer Model

April 15, 2008

Simlib to simulate a model of a time-shared computer facility considered by Adiri and Avi-Itzhak. A company has a computer system consisting of a single central processing unit (CPU) and n terminals. The operator of each terminal ‘thinks’ for an amount of time that is an exponential random variable with mean 25 seconds, and then sends to the CPU a job having service time distributed exponentially with mean 0.8 second. ………………………..
