This means the dimensions of your model can change without requiring changes to your expression of the problem.

Using LINGO, you can easily make your model 'scalable'. Models are easier for the developer to maintain and for colleagues to read and understand. The modeling language's similarity to standard mathematical notation makes it very easy to read. Very large models can often be efficiently expressed with LINGO in less than a single page. LINGO's modeling language can help you drastically cut your model development time. LINGO even allows you to express common sets implicitly, such as days of the week or months of the year. Taking advantage of sets is the foundation of LINGO's modeling language, the fundamental building block of the program's most powerful capabilities. Rather than requiring that you express an individual constraint for each set member, LINGO allows you to express the entire group of constraints in one concise statement. Often if a constraint applies to one member of a set, then a constraint of the same form also applies to each of the other set members. When building models, you typically find there are one or more sets of related objects (e.g., sets of factories, customers, vehicles, or employees). Your models are compact and easy to read. LINGO allows you to do things such as quickly express a series of similar constraints in a single compact statement. LINGO's modeling language lets you express your problems in a natural manner very similar to standard mathematical notation. One of LINGO's most powerful features is its mathematical modeling language. LINGO can exploit multiple CPU cores for faster model generation. Models are easier to build, easier to understand, and, therefore, easier to maintain. LINGO's modeling language allows you to express models in a straightforward intuitive manner using summations and subscripted variables - much like you would with pencil and paper. It lets you formulate your linear, nonlinear and integer problems quickly in a highly readable form. LINGO will help you cut your development time. LINGO provides a completely integrated package that includes a powerful language for expressing optimization models, a full featured environment for building and editing problems, and a set of fast built-in solvers. LINGO is a comprehensive tool designed to make building and solving Linear, Nonlinear (convex & nonconvex/Global), Quadratic, Quadratically Constrained, Second Order Cone, Semi-Definite, Stochastic, and Integer optimization models faster, easier and more efficient.
