Critical path method for the analysis of bituminous road transport network under fuzzy environment of various fuzzy quantities

Abstract

Determining the critical path in bituminous road transport network in the past period depended only on time and cost, whereas in current period the identifying the critical path has become complicated because of multi-criteria: time, distance, security, etc. We have proposed Integrated FAHP – FTOPSIS Methodology for determining the optimal critical path based on trapezoidal, hexagonal and octagonal fuzzy numbers. The aim of this research work is for transport department and society should have through the effective methodology to avoid critical path and for safe journey. Moreover, this methodology will carry for future course of action through Ministry of Road Transport to make safe roadways which is helpful and useful for effective transportations. We are exhibiting the proposed methodology by giving a numerical example and comparing trapezoidal, hexagonal and octagonal fuzzy numbers.
