Comprehensive benefit evaluation method for photovoltaic power generation projects based on cloud model

Engineering projects exert a profound influence on diverse facets of society, encompassing individuals’ livelihoods, the broader economy, and the environment. Assessing the benefits of projects is crucial in governmental decision-making processes and in determining investments in social capital. This paper introduces a cloud-based method for evaluating the comprehensive benefits of engineering projects, specifically focusing on photovoltaic power generation projects. First, the paper constructs a comprehensive benefit evaluation system tailored to photovoltaic power generation projects. Next, it calculates the weights of the indicators within the evaluation system. By merging the subjective weights derived from the fuzzy analytic hierarchy process (FAHP) with the objective weights gathered from grey relational analysis (GRA), the method yields a more scientifically sound combined weight. Finally, the combined weight is assimilated into the cloud model, leading to the creation of a comprehensive evaluation benefit cloud model tailored to the projects. The effectiveness of the proposed methodology is substantiated through a real-world example of a photovoltaic power generation project.
