Bilevel Optimization for Capacity Contingency Debottlenecking Considering Trade-Offs within the Waste Oil Supply Chain

Selena Kian Yii Song, Lip Siang Yeo, Sin Yong Teng, Sue Lin Ngan, Viknesh Andiappan, and Bing Shen How

Abstract

A bilevel optimization model is developed to synthesize an optimal waste oil recycling supply chain design in economic and environmental aspects while considering its overall resiliency in addressing major disruptions.

JOURNAL

Planning and Optimisation of Renewable Energy Systems for Decarbonising Operations of Oil Refineries

Clarence Yii Fang Lau, Yick Eu Chew, Bing Shen How and Viknesh Andiappan

Abstract

A multi-period optimisation model is developed via mixed integer linear programming to determine the optimal renewable energy system in terms of cost and its optimal energy storage technology to enhance its flexibility for oil refinery operations.

JOURNAL

Decarbonization of Energy Operations for Hard-to-Abate Industries Through Smart Energy System Optimization

Yick Eu Chew, Bing Shen How, Jaka Sunarso, Irene Moser and Viknesh Andiappan

Abstract

A multiperiod MILP model optimizes smart energy system and decarbonization strategies tailored for cement plant. Neither decarbonization strategy alone achieves net-zero emissions, but together they cut emissions effectively.
