Abstract: A system evaluates residential satisfaction of residents living in a building, based on preferred sections of the residents predicted using personal tendencies of the residents and sensing data collected through sensors in the building. The system may include a server that evaluates the residential satisfaction of the residents by analyzing a correlation between the sensing data and residential satisfaction information obtained from the survey conducted through a communication manner including the user terminals, and controls an air conditioning system in the building of a control target by predicting a feature-based preferred section of the users through random forest model learning.

Abstract: An energy-saving dynamic production scheduling operation method for a parallel heat treatment process which handle processes in parallel is provided. The energy-saving dynamic production scheduling operation method includes: acquiring, by a production scheduling operation system, dynamic state information of a process of each processor; scheduling, by the production scheduling operation system, the process of each processor based on the dynamic state information; and deriving, by the production scheduling operation system, an estimated cost based on a result of generating a schedule regarding the process of each processor. Accordingly, an input sequence of heat treatment target products and a combination schedule can be optimized by reflecting dynamic state information (a product inputted to a corresponding heat treatment furnace, estimated heat treatment start and end times, cooling and heating states, etc.) of a plurality of heat treatment furnace which handle processes in parallel.

Abstract: Proposed is an apparatus, system, and method for conducting a company-customized work evaluation of employees based on work sincerity and work concentration to induce employees toward the ideal talent pursued by the company. The apparatus may receive an input of setting values for work sincerity and work concentration each including a plurality of evaluation items, setting values for weights for the respective evaluation items, and setting values for satisfaction/violation conditions from a manager terminal. Additionally, the apparatus may receive data on work sincerity and work concentration obtained by collecting and counting event information on satisfaction/violation for each evaluation item according to an employee's work from a plurality of employee terminals. Also, the apparatus may perform work evaluation on a plurality of employees via a work evaluation algorithm that uses the work sincerity and work concentration data and the weights as input values.
