The implementation of fuzzy trapezoidal critical path method in a housing project

Abstract

Project scheduling is one of the most important elements in a project. Scheduling using deterministic methods often has constraints in estimating the completion time for a project. Using deterministic methods that there is only 1 duration to determine the completion of an activity where this will be risky if there is a delay, so in this study try to implement the scheduling method using a trapezoidal fuzzy critical path, where there are 4 durations is used to estimate the completion of a job. In this analysis, the project data was obtained from the VB housing project. Based on the available data, several research scenarios were obtained to find the effect of changes in the factors contained in the trapezoidal fuzzy method towards the changing of the final duration and critical path in the project. The results of this analysis were found that the changes in the critical path could be influenced by changes in alpha values and the duration of the activity range. The total project duration range is affected by the shape of the fuzzy diagram.
