This manual describes several advanced features of the gPROMS package. These in-
clude:
 The gPROMS Foreign Object Interface (see chapter 2).
Foreign Objects are external software components that provide certain compu-
tational services to gPROMS MODELs. These include physical property packages,
external unit operation modules, or even complete computational
uid dynam-
ics (CFD) software packages. This chapter explains how to make use of foreign
objects that are already interfaced to gPROMS; and also how to develop and
interface your own foreign objects.
 The gPROMS Physical Property Interface (see chapter 3).
Physical property packages form a special type of foreign objects (see above) that
are encountered very frequently in practice. The gPROMS Physical Property
Interface (PPI) de nes a standard set of physical property facilities that should be
supported by all physical property packages interfaced to gPROMS. Some widely
used physical property packages are already interfaced to gPROMS; details on
how to use them are also provided in this chapter. Finally, the PPI provides
a particularly convenient way of interfacing new physical property packages to
gPROMS.
 The gPROMS Foreign Process Interface (see chapter 4).
The Foreign Process Interface (FPI) allows gPROMS simulations to interact with
external software such as distributed control systems and operator training pack-
ages in order to exchange data and other information. The interaction takes the
form of a special set of elementary actions within the gPROMS TASK language.
FPI is particularly useful for embedding gPROMS simulations within larger soft-
ware systems.

This manual describes several advanced features of the gPROMS package. These include:
 Dynamic Optimisation in gPROMS (see chapter 2).
gPROMS can be used to optimise the steady-state and/or the dynamic behaviour
of a continuous or batch process. Both plant design and operational optimisation
can be carried out. The form of the objective function and the constraints can
be quite general. Moreover, the optimisation decision variables can be either
functions of time (\controls") or time-invariant quantities.
 Parameter Estimation in gPROMS (see chapter 3).
gPROMS can be used to estimate the values of model parameters from the results
of one or more experiments. Both steady-state and dynamic experiments can be
used for this purpose. The experiments can employ di erent initial conditions
and/or operating sequences; the sets of variables measured by each experiment,
as well as the times at which these measurements are taken, may also di er from
experiment to experiment.
 The gPROMS Foreign Object Interface (see chapter 4).
Foreign Objects are external software components that provide certain computational
services to gPROMS MODELs. These include physical property packages,
external unit operation modules, or even complete computational
uid dynamics
(CFD) software packages.
