Contribution to an informed choice of social housing in cameroon through the use of a multicriteria method of analysis: a decision-making tool

Cameroon's population growth is very high and makes access to housing difficult over time. The decision-making engineering that governs production the current planning and social housing presents many weaknesses. Among them, the production rates are very insufficient and the dominant constructive system is the reinforced concrete - hollow cement bonded hitch. The major challenge of the article is to propose an alternative decision-making approach to better integrate locally abundant materials in the various agro-ecological zones of Cameroon. A detailed analysis of the socio-economic and technical data is carried out. Multicriteria analysis, coupled with fuzzy logic, classifies constructive systems according to their degree of consensus with respect to the criteria considered. For the sake of financial viabilisation, the best constructive systems are analyzed by making a comparison between the public contracting and the public-private partnership approaches. The reinforced concrete (structural material) - solid wood (wall material) system has a satisfactory overall agreement.
