Selecting the Best 3D Concrete Printing Technology for Refugee Camp’s Shelter Construction Using Analytical Hierarchy Process: The Case of Syrian Refugees in Jordan

Upgrading the Syrian refugee shelter design serves humanitarian needs, especially since currently used T-shelters have a life span of 2–4 years, and there are no clear signs an imminent return refugees to their country, even after end civil war. The use 3D concrete printing can provide promising method construct new durable shelters with long better protection against extreme change in desert climate, privacy, cultural constraints. This research aims multi-criteria decision methods—in particular, Analytical Hierarchal Process (AHP) method—to select best these shelters. proposed model takes following into consideration: machine’s technical characteristics, building structure economic environmental aspects. three basic developed technologies—contour crafting, D-shape, printing—were as alternatives model. results show that contour crafting is technology for this application, inconsistency test sensitivity analysis indicate effective reasonable ranking.
