External Procedures and Functions
Why call external procedures
Even though AIMMS offers easy-to-use multidimensional data structures
combined with a powerful programming language, there are often good
reasons to relay parts of the execution of your model to external
procedures and functions written in e.g.
The capability to call external procedures and functions in your AIMMS
application allows you
to re-use existing software (e.g. a library of financial functions, or a collection of accurate, nonlinear process models),
to speed up selected computations by making use of dedicated data structures which are difficult to implement in AIMMS itself, and
to provide links to external data sources (e.g. on-line data feeds or proprietary databases).
This chapter describes the steps you have to follow for linking libraries of external procedures and functions to AIMMS. Such procedures and functions can be used to manipulate AIMMS data during the execution of a model. In addition, external libraries may contain functions that can be used inside the constraints of a nonlinear mathematical program.
