CASE STUDIES IN COMPUTER SIMULATION. A COMPARISON: PERT VS. TRANSIM NETWORK ANALYSIS,

Abstract

Estimates of time to complete a naval ship boiler repair as part of a regular ship overhaul, are developed by two different analytical methods, PERT and TRANSIM, in order to conduct a comparison between the two techniques of network analysis. The latter is a Monte Carlo-type, general-purpose simulator, capable of including in the analysis the variances of activity times as represented by individual probability distributions. This permits utilization of input activity distributions based on actual histograms and develops variations in the critical path due to the stochasticity of activity times. A comparison of the results obtained with the two techniques provides reliable measures of the errors due to PERT assumptions and approximations. (Author)
