Selection of Tower Crane using Multi-Criteria Decision-Making Techniques

Devika Nayal , Dr. Virendra Kumar Paul , Kuldeep Kumar

Within the range of equipment used at site, owing to its extensive usage, it is stated in various literature that the tower crane becomes a pivotal equipment at site and its optimal performance at minimal cost is most desired. Due to the importance of tower cranes at site, this paper proposes a system of selection of tower cranes at site using multi-criteria decision- making (MCDM) model for the same. The study also attempts to apply the model on a case study, finding of which shall be presented in the report. The methodology adopted for the selection is Technique of Order Preference Similarity to the Ideal Solution (TOPSIS) method and the result have been compared against those obtained by Multicriteria Optimization and Compromise Solution (VIKOR) and Simple Additive Weighing (SAW). The technique selected for MCDM is as crucial as the factors considered for selection since the results may vary. Hence, on the basis of this variation, more than one MCDM technique can be employed for a better understanding of the suitability of the equipment.
