Abstract. The CoSoTIA (Concentrated Solar Technologies for Industrial Applications) project initiated by the CRTI center in collaboration with the URMPE unit concerns the study and development of CSP solar concentrators for industrial applications. In the present work, we present decision support tools for the choice of a solar concentration technology for sites in Algeria. They will be used for the comparison between different technologies of solar concentration e.g.: cylindro-parabolic, parabolic, solar tower, etc. The models used include project costs and site characteristics; they incorporate also engineering knowledge (economic, social, technical and environmental). The information needed for decisionmaking produced by these tools is: the total cost of the project, indicators with economic, social, technical and environmental aspects. The case studies presented were conducted under the SAM Advisor environment, which was developed to evaluate the capacities to implement CSP project in order to produce expertise for the different actors through an application on a given site (by the client). Four case sites in Algeria and for two types of solar concentrator plant are studied and presented. A comparative study was conducted and for each site the best CSP was deduced and commented. Keywords: Decision support · Multicriteria analysis · Solar concentration · CSP · SAM advisor
1 Introduction The environmental problems caused by greenhouse gas emissions during the exploitation of fossil fuels and the increasing demand for electricity have spurred the search for alternative energy resources. Concentration solar technologies offer the possibility of satisfying the world’s demand for electricity (Goetzberger and Greubel 1977, Seitz et al. 2014, Imenes and Mills 2004) but are still conditioned by the weather conditions of the sites, the high cost of kWh and the need for optimal storage capacity (Sylvain 2007) for continuous operation, etc. © Springer Nature Switzerland AG 2020 B.

Making a decision usually requires the simultaneous optimization of several often contradictory objectives. Tools such as multi-criteria analysis are therefore very useful for the decision maker (Mena 2000, Tsoukiàs 2007). The multicriteria approach makes it possible, based on multiple criteria and decision maker preference conditions, to choose the best type of CSP technology taking into account a maximum of criteria. In many new thermal plants installation projects (Stoddard et al. 2006), decision-makers are faced with complex problems of large size and multi-purpose. To achieve these goals, effective decisions must be made to avoid the following problems: – The incompatibility of installation site with the ty
