réalisables

Réalisables is the plural form of the French adjective réalisable, meaning capable of being realized, achieved, or produced under current conditions. In everyday and technical language, it is used to characterize plans, goals, outcomes, or elements that can be carried out within given constraints such as time, resources, or rules.

In planning and management, something described as réalisable is practical and attainable. The term is often paired with qualifiers like “à court terme” or “dans le cadre du projet” to emphasize feasibility within a specific context. The concept helps focus objectives on what can realistically be delivered rather than on idealized outcomes.

In mathematics and operations research, réalisables refers to feasible solutions. The ensemble des solutions réalisables, or the régiòn réalisable, comprises all variable assignments that satisfy all constraints, such as equalities and inequalities. The feasible region in a linear programming problem is a classic example, typically forming a convex set that allows standard optimization methods to operate.

The related noun réalsabilité (or feasibility as a concept) and the noun réalisabilité describe the quality or state of being realizable. In contrast, terms such as irréalisable denote impossibility under the given constraints. In practice, designers, engineers, and policymakers assess réalisables to balance ambition with practicality, ensuring plans are both aspirational and executable. Synonyms include faisable and viable, while faisabilité is the more common noun for feasibility in French.
