A Multi-Objective Optimization Business Model for Non-Commercial Port Sustainability

Abstract

Increasing port productivity will affect increasing port income. To be able to achieve this, Resources already in place must be optimized. One option cannot adequately address the complexity of factors affecting port productivity. A method called multiple objectives can assist decision-makers in logically allocating resources by using models for numerous distinct purposes at once. Several objectives must be achieved, including maximizing revenue, minimizing environmental costs, and maximizing the number of workers to design a noncommercial port business optimization model. These goals contain different or even contradictory aspects. For this reason, we need a method that can provide an optimal solution: a meeting point (trade-off) of these goals. The goal programming method can solve problems optimally with more than one (multi) goal objective. The research results show that the product combination resulting from goal programming optimization is more profitable than what the company has done so far. Optimization results fulfil aspects of sustainable port management, namely economic, social, and environmental elements. With this optimization method, port managers can optimize their ports in a balanced way between seeking profits, advancing job growth and minimizing environmental impacts, thus leading to sustainable port management.
