Multi-criteria decision making model for the applicability of additive manufacturing technologies in buildings

Abstract

With the additive manufacturing technique, which has been used in many industries for years but is considered new in the construction industry, it is possible to make houses that are cost efficient, faster, higher quality, safer, more flexible, with a high level of completion rate and produced with the least error in a shorter time. With the additive manufacturing technologies that have become increasingly widespread in the field of construction for the last 10 years, almost ready-to-use structures are made today. Offices produced in as little as a week, residences produced in a day, sewers produced in one or two hours, environmentally friendly walls, benches, etc. In this context, as a result of the literature research, criteria were put forward on the use of additive manufacturing in the field of construction and its features. A multi-criteria decision making model was proposed as a result of filling the evaluation forms prepared according to the determined criteria and analyzing them with the fuzzy DEMATEL method (The Decision Making Trial and Evaluation Laboratory). The criteria or criterias that are advantageous or disadvantageous were found by showing the order of importance according to the weight of the criteria in the proposed decision making model with the determined sample. The proposed model will help the contractors, designers and implementers who want to use this production system to make a ranking according to their priorities in the building to be built, and to help decide whether the project determined with this production system should be carried out.
