A Multi-attribute Urban Metro Construction Excavated Soil Transportation Decision Making Model Based on Integrated Fuzzy AHP and Integer Linear Programming

Warapoj Meethom, Titiwat Triwong

Abstract


There has been a lack of proper decision making referring to the excavated soil transportation industry from urban metro construction areas and around metropolis Bangkok due to the implemented heavy truck ban on certain streets. Therefore, this research aims to develop a decision making model to support the metro tunnel excavation project engineer with a decision system. This will aid the excavated soil transportation solving the problem of insufficient sail reserves at the construction site, and save transportation costs within the time constraints. This will be achieved by applying qualitative decision criteria affecting the operation in Bangkok by developing an Integer Linear Programming (ILP) model. This model also applies the Fuzzy Analytic Hierarchy Process (FAHP) to calculate the optimal transportation costs and the related qualitative criteria to help increase the decision makers’ flexibility in various cases.
