A Cloud- and Game Model-Based Approach to Project Evaluations of Sustainable Power Supply Investments

Abstract

In light of electrical energy’s increasing role in economic systems worldwide, prioritizing investments in sustainable power supplies has become paramount. This study proposes a model based on cloud theory and game theory to evaluate sustainable power supply investment projects. It establishes a foundation for assessing the merits of power supply investments, which are crucial for continuous electricity provision and economic advancement. By integrating an enhanced analytic hierarchy process and the entropy method, the study develops a dual-weighted evaluative index system. This hybrid approach addresses ambiguities and enhances the weight determination accuracy, which, when applied to the Liaojiawan Transformer Substation, verifies the project’s high benefit level, corroborated by empirical data. This innovative methodology offers a strategic framework for future power supply investments.

Dynamic Multi-Attribute Decision-Making Method for Risk-Based Ship Design

“…The third category integrates subjective preference and objective importance. Common methods for calculating comprehensive weights generally include the linear weighted synthesis method [31], the sum of squared deviations method [32], and the game theory method [33]. This study adopts game theory to determine the comprehensive weights.…”
