tasks and resources, allowing for efficient use of energy by controlling the operation of these devices according to current needs. Meanwhile, the variable indicating loading capacity has a direct impact on energy usage. Optimal utilization of this capacity can lead to cost reduction associated with energy efficiency and potentially reducing energy load variation. All these variables, analyzed in the context of electricity usage, provide crucial information for decision-making regarding the optimization of processes and resources to effectively manage energy consumption and operational costs. Monitoring and analyzing them can lead to greater energy efficiency and a reduction in the negative impact on the environment. The Table 1 presented below provides a summary of the variables with their description. For the variables presented, 240 records representing the values of binary and continuous states were collected. Table 1: Variable characteristic by groups Variable_group Type Description
