Description: A yes-no model is a type of optimization model that involves binary decisions, where the options are limited to two possibilities: yes or no. This approach is fundamental in decision-making as it simplifies complex problems by reducing alternatives to clear and direct choices. Yes-no models are particularly useful in various situations requiring categorical responses, such as project selection, resource allocation, or strategy planning. The main characteristics of these models include their ability to mathematically represent problems, facilitating the analysis and optimization of decisions. Additionally, they are applicable in various fields, from operations research to artificial intelligence and other areas of technology, where the goal is to maximize or minimize an objective under certain constraints. The relevance of yes-no models lies in their versatility and effectiveness in addressing problems that require discrete decisions, allowing analysts and decision-makers to quickly evaluate the implications of each option and select the most suitable one based on predefined criteria.
