Patent number: 10394266Abstract: According to embodiments of the present invention, the energy consumption assessment is done by identifying the benchmark production processes or enterprises. First, a process similarity between a target production process and a candidate production process is determined based on energy consumption units (ECUs) involved in the target production process and the candidate production process. In response to the process similarity being greater than a first threshold, an energy consumption similarity between the target production process and the candidate production process is determined based on a factor that has influence on energy consumption of at least one of the ECUs. In response to the energy consumption similarity being greater than a second threshold, the candidate production process is identified as a benchmark for assessing energy consumption of the target production process.Type: GrantFiled: August 26, 2015Date of Patent: August 27, 2019Assignee: International Business Machines CorporationInventors: Feng Jin, Bin Li, Xin Jie Lv, Qi Ming Tian, Lei Ye, Li Zhang, Gang Zhou

Patent number: 10359280Abstract: A system, method and computer program product for tracking and identifying a polluted air mass's transmission trajectory in real 3-D space. In one aspect, a polluted air mass's transmission path identification is based on a monitoring of PM2.5 concentration in cubic volumes of an air mass. The method computes a transmission path of polluted air that considers wind-pressure conversion, the displacement estimation with mass concentration, and planetary boundary layer (PBLP height constraint) for 3-D cubic grids. The resultant determination of a polluted air mass's transmission trajectory in real 3-D space generates more practical and reliable results for intensive knowledge of the transport pathways and potential pollution sources in real 3-D space.Type: GrantFiled: April 28, 2017Date of Patent: July 23, 2019Assignee: International Business Machines CorporationInventors: Xin Xin Bai, Xin Jie Lv, Xiao Guang Rui, Xi Xia, Jian Yao, Wen Jun Yin, Wei Zhao, Yu Xin Zhao
