Abstract

Optimal site selection using multi-criteria decision analysis (MCDA) is an important step to support decision makers to locate places that benefit the maximum potential of technology's preconditions. As a new, emerging and renewable technology in Brazil, concentrated solar power (CSP) plays an important role in power generation mix, and it’s crucial to indicate the viability of Brazilian regions to CSP power plants. To achieve this goal, a detailed workflow of multi-criteria analysis based on geographic information system (GIS based AHP) is set in free software, in which criteria are selected from literature, acquired as geospatial data, weighted with parity matrices through online questionnaires filled by experts, processed on QGIS with weighted linear combination (WLC), and the results validated by its AHP consistency, thematic accuracy and comparative analysis with VIKOR and TOPSIS methodologies. As a product, sites are mapped according to viability indices, with higher values in most of Northeast, Central-west and Southeast regions of Brazil, showing good stability by its validation. Thereby, the workflow with free software allows the methodology to be replicated to support decision makers in locating viable and restrictive places for technologies.

基于地理信息系统（GIS）的多准则决策分析（MCDA）优化选址——以巴西聚光太阳能发电厂为例

使用多准则决策分析（MCDA）进行最佳选址是支持决策者定位能够最大限度地利用技术先决条件潜力的地点的重要步骤。聚光太阳能发电作为巴西一种新兴的可再生技术，在发电组合中发挥着重要作用，向聚光太阳能发电厂表明巴西地区的可行性至关重要。为了实现这一目标，在自由软件中设置了一个基于地理信息系统的多准则分析的详细工作流程（基于GIS的AHP），其中准则从文献中选择，作为地理空间数据获取，通过专家填写的在线问卷用奇偶矩阵加权，在QGIS上用加权线性组合（WLC）处理，并通过AHP的一致性、主题的准确性以及与VIKOR和TOPSIS方法的比较分析验证了结果。作为一种产品，根据生存能力指数绘制站点地图，巴西东北部、中西部和东南部大部分地区的值较高，通过验证显示出良好的稳定性。因此，自由软件的工作流程允许复制该方法，以支持决策者为技术找到可行和限制的地方。
