Monikriteerireititys

Monikriteerireititys is a term used in operations research and decision analysis to describe the process of selecting a route or path when multiple, often conflicting, criteria must be considered. Unlike simple shortest path algorithms that optimize a single objective (e.g., distance or time), monikriteerireititys acknowledges that real-world routing decisions usually involve a combination of factors. These factors can include cost, travel time, safety, environmental impact, accessibility, fuel efficiency, and user preference.

The challenge in monikriteerireititys lies in balancing these diverse criteria. Often, optimizing for one criterion will lead to a suboptimal outcome for another. For instance, the shortest route might be the most expensive or the least safe. Therefore, algorithms and methodologies for monikriteerireititys aim to find solutions that represent a good compromise across all relevant criteria.

Various techniques are employed to address this problem. Multi-criteria decision-making (MCDM) methods, such as Analytic Hierarchy Process (AHP) or weighted sum models, are frequently used to assign weights to different criteria and then evaluate potential routes based on these weighted preferences. Evolutionary algorithms, like genetic algorithms, can also be effective in exploring a wide range of possible routes and identifying Pareto optimal solutions, which are routes where no single criterion can be improved without worsening another. The application of monikriteerireititys is widespread, including logistics, transportation planning, network design, and even in areas like personal navigation systems where users might specify preferences beyond just speed.
