Abstract

This paper describes a decision-support system developed to assist practicing professionals in matching project parameters with characteristics of the various construction methods and evaluating the degree to which each method satisfies user requirements. The model, named Innovative Modular Procedure for Evaluation of Construction Technologies (I.M.P.E.C.T), combines concepts from constraint satisfaction techniques, linear algebra, calculus, and applied statistics. The proposed model employs a two-step selection process, namely a technical evaluation and a preference evaluation. At the technical evaluation stage, characteristics of each construction method are compared with the project's qualifying attributes (i.e. pipe diameter) to ensure technical soundness of the method. The preference evaluation process includes parameters considered to be controlled by the user (i.e. cost). The model determines the likelihood that each of the construction methods will satisfy the user objectives and rank it based on its utility value, which is equal to the sum of the product of each degree of user objective satisfaction and the probability of such an outcome. The proposed method represents a powerful decision-making model capable of addressing the complex and interacting technical, social, business, and risk aspects associated with many large trenchless technology projects.
