LRATCkurven

LRATCkurven is a term found in Scandinavian technical literature that refers to a specific curve used to represent relationships in data modeling, optimization, or planning problems. The precise mathematical form of the curve varies by source, and there is no universally accepted definition in English-language references.

Etymology and usage often reflect the linguistic roots of the term: kurven means “the curve” in Danish and Norwegian, while LRATC is an acronym whose expansion is not standardized across publications. In Danish-language sources, LRATCkurven commonly appears in discussions related to transport planning, resource allocation, or environmental modeling, where curves are used to illustrate trade-offs between competing factors.

Mathematical and practical characteristics described in the literature position LRATCkurven as either a parametric or an implicit curve derived from empirical data or a theoretical model. It may aim to capture relationships such as throughput versus latency, risk versus cost, or allocation efficiency as a function of a control parameter. Some descriptions emphasize monotonicity or piecewise smooth behavior, while others note potential convexity or concavity in different segments depending on the application.

Applications and references for LRATCkurven are found in niche publications, conference papers, and theses within Scandinavian academia and industry. The term is most often linked to optimization, control, or transport planning problems where the curve summarizes a critical trade-off.
