Two-sided assembly lines are designed to produce large and complex products, where workers can perform on both sides at the same time. This paper establishes a mathematical model for multi-objective two-sided line balancing problems with additional constraints (MOATALBP). The considers workers’ skill balance of line, aimings maximize efficiency minimize cost smoothness index. A harmony search a...

in today's competitive markets, with orientation companies towards customer satisfaction, customer relationship management (crm) is more complicated. the main question is how to identify profitable and key customers of company. companies can segmenting their customers into different groups based on the specific criteria by identify and analyzing the characteristics of their behavior. these...

With the rapid growth of electric vehicle (EV) ownership, problem increased peak loads on distribution networks due to large-scale EV integration needs be addressed. This study proposes an active network multi-objective optimization scheduling method. It takes into account charging demands EVs and aims minimize operating costs, reduce net load variance, maximize photovoltaic (PV) consumption ra...

Power system restructuring has changed transmission expansion planning (TEP) and caused many complications due to conflicting contradictory objectives. The capacity would significantly affect the revenue of investor-owned renewable energy sources (RESs). Thus, investment decisions on merchant RESs must be considered in TEP studies conducted by operator (TSO). In this regard, paper aims propose ...
