Abstract
A plant construction project always involves lots of activities. Precise
information about the activities duration is unfortunately unavailable due to the uncertain
resources capacity. The fuzzy program evaluation and review technique (PERT) has been
widely applied to solve the fuzzy project scheduling problem. This paper presents an
extended fuzzy PERT approach with four major improvement aspects to support the
construction project scheduling management: 1) Evaluate operation fuzzy times based on
available working volumes, resources quantity and fuzzy capacity of resources, 2) Adopting
a maximal i levelcut method to compare the fuzzy precedent activities times to
determine the reasonable earliest starting times of each activity, 3) Using fuzzy algebra
method instead of fuzzy subtraction method to compute the fuzzy latest starting times and
4) Developing a project scheduling risk index (PSRI) to assist the decision maker to
evaluate the project scheduling risk. Simulations experiments are conducted and
demonstrated satisfactory results.
