Abstract (English): The purpose of this article was to optimise the cost of the energy consumption of an industrial complex that was using three energy sources: industrial electricity, natural gas, and solar energy. Before undertaking any optimisation action, we carried out an in-depth examination of the company's energy system. This action was positioned as an essential pivot for collecting energy data according to: Source (gas, electricity); Equipment or production tools; Usage (heating, cooling, lighting, ventilation, etc.). The in-depth examination of the company's energy system made it possible to identify the energy consumption of the equipment and the costs associated with it for a year of operation. With an objective of energy and economic performance, the simplex algorithm was implemented to resolve the energy mix model and machine hours, according to the two-phase technique applied first to the energy problem and second to resolving the time problem.

Abstract (Afrikaans): Die doel van hierdie artikel was om die koste van die energieverbruik van 'n industriële kompleks wat drie energiebronne gebruik het te optimeer: industriële elektrisiteit, aardgas en sonkrag. Voordat ons enige optimeringsaksie onderneem het, het ons 'n in-diepte ondersoek van die maatskappy se energiestelsel uitgevoer. Hierdie aksie is geposisioneer as 'n noodsaaklike spilpunt vir die insameling van energiedata volgens: Bron (gas, elektrisiteit); Toerusting of produksie gereedskap; Gebruik (verhitting, verkoeling, beligting, ventilasie, ens.). Die in-diepte ondersoek van die maatskappy se energiestelsel het dit moontlik gemaak om die energieverbruik van die toerusting en die koste daaraan verbonde vir 'n jaar van bedryf te identifiseer. Met 'n doelwit van energie en ekonomiese werkverrigting, is die simpleksalgoritme geïmplementeer om die energiemengselmodel en masjienure op te los, volgens die tweefase-tegniek wat eerstens op die energieprobleem toegepas is en tweedens om die tydprobleem op te los.
