Examples of General Algebraic Modeling System

The General Algebraic Modeling System (GAMS) is an advanced programming language and platform, particularly used for mathematical modeling of complex systems. It offers flexibility and robustness, allowing professionals to find solutions to a variety of real-world problems. Here are three examples of GAMS being used in the real world:

Optimization of Energy Systems: GAMS has become a popular tool for researchers to model and optimize energy systems for power generation, transmission, and distribution. In one example, GAMS was used to create an integrated model of the OrcaFlex offshore wind farm in Scotland to find the most cost-effective cable configuration and layout. By using GAMS for this project, researchers were able to determine the best possible design to reduce overall costs while maintaining system efficiency and reliability.

Agricultural Planning and Management: GAMS has been used to optimize irrigation systems, crop management, and agricultural production planning. For instance, researchers from the University of California, Davis, developed a GAMS model to optimize water distribution scenarios for agricultural sites in the Central Valley of California. This model helped policymakers and stakeholders to find the most efficient water management strategies that both conserve water and maximize agricultural production.

Supply Chain Management and Logistics: GAMS is commonly used in supply chain management and logistics to model and optimize complex distribution networks, vendor relationships, and inventory management. One such example is the study carried out by researchers at the Chalmers University of Technology in Sweden, who utilized GAMS to evaluate strategic investments in the European wood fuel supply chain. By using GAMS, they were able to optimize the supply chain network and develop recommendations for investments to reduce transportation costs and carbon emissions.
