Description: The term ‘fractional’ refers to a model that includes fractional variables, meaning those that can take non-integer values. In the context of model optimization, this implies that variables can be represented as fractions, allowing for greater flexibility and precision in representing complex problems. Fractional models are particularly useful in situations where decisions are not simply binary (yes/no) or integer-based, but require a more nuanced allocation of resources or capacities. This characteristic enables researchers and analysts to tackle problems in various fields, such as economics, logistics, and engineering, where optimal solutions are not always integer-based. The inclusion of fractional variables can lead to a better approximation of reality, facilitating more informed and effective decision-making. In summary, fractional models are a powerful tool in optimization, allowing for a richer and more detailed representation of the problems to be solved.
