An Oil and Gas Retrofitted Carbon Capture Utilisation and Storage Value Chain: A Green Industry
Abstract: Fossil fuel consumption continues to be crucial to industrialisation. It has continued to contribute to over 80% of the world’s total primary energy production for the past three decades. The primary cause of climate change, however, has been identified to be the rising greenhouse gases emission from the use of fossil fuels. Hence, a proposed solution to this is to switch to greener, lower-carbon energy sources. Despite growing concern over …

A Study and Performance Evaluation of Evolutionary Optimization Techniques for Multi-objective Master Production Scheduling Problems
Abstract: Master production schedule (MPS) can effectively and efficiently synchronize the operations in any organization. MPS, which is posed as one of the multi-objective parameter optimization problems, is a plan that determines optimal values of products to be produced. For many engineering optimization problems, more competitive and optimal solutions can be obtained by using Heuristic evolutionary optimization algorithms. Among these, two main algorithms considered here are the differential evolution (DE) whose …
