Model Libraries From the early stages of the development of GAMS we have collected models to be used in libraries of examples. Many of these are standard textbook examples and can be used in classes on problem formulation or to illustrate points about GAMS.
Others are models that have been used in policy or sector analysis and are interesting for both the methods and the data they use. These model libraries are included with all GAMS systems and are also available online.
To deliver GAMS with the best performance we are using the Amazon CloudFront web service, a global network of edge locations for content delivery.
GAMS is a high level modeling system for mathematical programming and optimization. It consists of a language compiler and a range of associated solvers.
Data Entry: Parameters, Scalars and Tables - Three basic forms of GAMS data types : Parameters, Scalars and Tables. – Data Manipulations with Parameters - The declaration and assignment of GAMS parameters. – Variables - The declaration and attributes of GAMS variables. – Equations - The definition and declaration of GAMS equations. – Model and Solve Statements Model - The specificiation of a GAMS model and how to solve it. – GAMS Output - The control of GAMS compilation output, execution output, output produced by a solve statement, and error reporting. – Conditional Expressions,
GAMS是灵活而强大的.模型可以方便的从一个计算机平台移到另外一个,只要GAMS已经在每个平台被安装好.GAMS很容易进行敏感度分析.使用者能够方便的规划模型来求解一个成分的不同值,然后生成一个输,列出了每种情况的解决方案特征.模型能够同时被开发和文档化,因为GAMS允许使用者包含解释性的文本来作为符号和等式的定义和解释. GAMS不断的在被增强和扩展.2.25版本包含了多个语言扩展,例如在一个循环中的SOLVE声明,INCLUDE声明,IF-ELSE声明,和使用PUT声明进行报告编写的功能.
