Abstract
This paper aims to introduce a quantitative method to builders for the most appropriate material selections based on multiple attributes and integrate decision group member opinions throughout bidding process. In this respect, a new model used together with the Analytic Hierarchy Process (AHP) and fuzzy Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA), multi-criteria decision methods are proposed. In a real decision process, there are many uncertainties and ambiguities. In fact decision makers cannot always provide practical guidelines and especially precise judgments due to time limitations. The intelligent model proposed demonstrates that the AHP and fuzzy MOORA approach can not only be used easily to imitate the decision duration in the material selection but also the results obtained from this work provide contractors valuable insight into the material selection problem. At the same time, the quantitative analysis method based on the appropriately raised floor materials along the bidding process enables the builders to use their restricted resources more expeditiously and enhances considerably the possibility of winning agreement, as one of the most striking points deduced from the present study. In short, the model with AHP and fuzzy MOORA approaches can assist the builders to improve resolutions for the bidding.
Highlights
Firms must exhibit the high capability to evaluate diverse bidding states successfully in extremely competitive construction market so that they keep up with today’s conditions
The proposed model created for Analytic Hierarchy Process (AHP) and fuzzy MOORA methods for the raised floor choice practice consists of three simple phases:
The AHP and fuzzy MOORA methods are used in an integrated manner along with the model proposed
Summary
Firms must exhibit the high capability to evaluate diverse bidding states successfully in extremely competitive construction market so that they keep up with today’s conditions. Contractor’s decision is seriously affected by various factors and influences as All kinds of installations as regards the electricity and computer cables can be conveyed to desired points by passing them through the empty spaces under the raised flooring. The selection of raised floor panels for office decoration is known as a commonly difficult decision-making problem. The raised floor panels are obtained from the supplier companies and are tested in terms of compliance with the standards for technical and physical properties. During the evaluation of the materials, the physical, technical and price criteria are considered seriously, and the AHP and fuzzy MOORA analyses are conducted on the real values of secondary criteria connected to the primary criteria
