Interval Analysis and DEMATEL-Based Reliability Apportionment for Energy Consumption Optimization With Energy Internet

Energy Internet represents a critical breakthrough that allows traditional energy to be transformed into intelligent energy. In this regard, the reliability apportionment technologies for modern products within Energy Internet deserve more attention because they can ensure the reliability optimization of different functional modules of systems. And because of the growingly serious energy crisis, environmental protection has become much more urgent, which requires industrial products to be more environmental friendly. However, traditional reliability apportionment methods can not do this. First, in design phase of product, most of them tend to ignore the environmental attributes, including carbon emissions and resource efficiency. Second, they fail to process the uncertainties of reliability apportionment, which is inevitable and important efficiently. Third, they pay insufficient attention to the correlations among product subsystems, which greatly influence the different product functions. To overcome these drawbacks, a reliability apportionment model based on the interval analysis and decision-making trial and evaluation laboratory is proposed. The validity of the proposed method is demonstrated by a case study.
