The document summarizes how Essar Oil leveraged an operations simulation program conducted by enParadigm to improve refinery operations and profitability. Senior managers from various refinery functions participated in a 2-day simulation where they operated virtual refineries and had to make real-time operational decisions. This allowed them to gain a wider business perspective on how their daily decisions impact other departments and the company's performance. As a result, participants implemented various initiatives like aligning maintenance schedules to reduce costs, optimizing resource allocation, and micro-innovations to streamline processes. The intervention helped Essar Oil improve cost control, resource optimization, and operational effectiveness.
