The parameters for this simulation model are developed from the data collected at the metal fabrication company. Failure data are collected and used to identify the failure characteristics of each machine. By using the Kolmogorov-Smirnov test it is found that each data set is best represented by the Weibull distribution; a distribution often used to model equipment failures. The Weibull distribution is defined by a scale and shape parameter. The scale parameter represents MTBF and the shape parameter represents failure rate. A shape parameter of 1.0 represents a constant failure rate. However,as the shape parameter increases the probability of a failure occurring increases as well. The Weibull distribution for Machine 1 is characterized by a MTBF of 6,400 minutes (used as the scale parameter) and a shape parameter of 1.34. Machine 2 is characterized by a MTBF of 4,584 minutes and a shape parameter of 3.37, and Machine 3 is characterized by a MTBF of 10,187 minutes and a shape parameter of 2.43.
