Evaluating the productivity of pre-fabricated and in-situconcrete buildings for post-disaster settlement using multi-dimensional decision-making model (VIKOR)

Iran is one of the natural disaster-prone countries due to its geographical location. The use of the traditional construction system in the residential building, before and after the natural disaster has caused a lot of financial losses and increase in the death toll. Buildings with durable structures, in order to provide safety for residents, are one of the essential requirements of a safe city. One of the essential requirements of a safe city is to have buildings with strong structures to provide safety for residents. Therefore, it is necessary to identify structural systems with minimum risk of damage in disasters and less time to build in the post-disaster for reconstruction and settlement. Pre-fabrication is one of the solutions that, despite the advantages and influential role in the post-disaster settlement, is still not common in Iran. The research aims to provide measurable evidence of the benefits of this technology in post-disaster settlement to speed up stakeholders’ decision-making process and encourage their investment in pre-fabrication. Negin Pardis Residential buildings have been selected as a case study. The criteria have been defined, confirmed and screened by the Delphi method, then the criteria weighted using the AHP method, and the VIKOR method has been used for ordering the options. After analysing the three alternatives in the construction systems, two groups of concrete and compound semi-prefabricated buildings were identified as the preferred system for post-disaster productivity and settlement.
