A Study of Energy Statistics Based on Energy-Tree

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.
