A Statistical Method of Energy ConsumptionBased on Energy-Tree

【摘要】：正Combined with the national energy policy and the actual project requirements,the author studies a statistical method of energy consumption based on energy-tree,in order to reduce corporate energy consumption,improve enterprise efficiency and optimize enterprise direction.Firstly,the author establishes energy-tree model that includes an entity tree that solid parent-child relationship between entities and a table that solid many-to-many relationship between entities and energies.Secondly,the author studies energy-tree recursive statistics.Finally,the author applies the research result to actual projects.Practice shows that the statistical method of energy consumption based on energy-tree is an efficient and reliable method of energy consumption.
