Multi-Criteria Decision Analysis (MCDA) is a structured approach used to evaluate and prioritize different options based on multiple criteria. It helps decision-makers assess the trade-offs between conflicting objectives, such as cost, quality, and environmental impact. By quantifying preferences and weighing various factors, MCDA provides a clear framework for making informed choices. This method is widely applied in fields like environmental management, healthcare, and urban planning. MCDA can involve techniques such as scoring systems or ranking methods, allowing stakeholders to visualize the implications of their decisions and select the best alternative based on their specific goals and values.
