The document is a reference manual for the Industrial Programming Language (IPL) developed by Industrial Algorithms LLC, detailing its ability to model and solve complex industrial optimization problems like planning and scheduling. It specifies how IPL integrates with various programming languages and how it operates in conjunction with the Industrial Modeling Language (IML) for data interchange. The document also outlines the functions used for configuring both static and dynamic model data within the IPL framework.

2. Introduction
The IPL code can be programmed in any computer programming language that can interact with
dynamic link or shared object libraries and then can be used to call our IMPL modeling and solving
platform. IMPL is an acronym for Industrial Modeling and Programming Language provided by
Industrial Algorithms LLC. The IPL code allows the user to configure and capture the necessary data to
model and solve large-scale and complex industrial optimization problems (IOP's) such as planning,
scheduling, control and data reconciliation and regression in either off or on-line environments. IPL,
also known as the IMPL Interacter, is a complement to IML (known as the IMPL Interfacer) which means
that they can be combined together in any arrangement or combination. That is, a portion of the model
can be configured in IML/IPL and the remaining portion can be configured in IPL/IML. In addition, all
terminology and nomenclature used in IPL are consistent with IML given that their data is
interchangeable and exchangeable. Ultimately, once all of the static and dynamic model data have been
configured using IML and IPL, then IMPL’s Modeler will create or generate the necessary IMPL sets, lists,
parameters, formulas, variables and constraints (as well as the derivatives and expressions).
All integers are 4-bytes (long), all reals are 8-bytes (double precision) and all strings are 64-bytes unless
otherwise stated. The return status for the integer functions is zero (0) for successful and non-zero for
unsuccessful which usually implies that the unit-operation-port-state names and/or the quality name
was not recognized.
Static Model Data (Non-Time-Varying)
Static model data are used to configure the model and are non-time-varying (immutable or constant)
over the past/present and future time-horizons.

Dynamic model data are used to configure the model and are time-varying (mutable or non-constant)
over the past/present and future time-horizons. All dynamic model data is digitized into discrete-time
for quantity, logistics and quality problems or digitized into distributed-time for quantity and quality
problems. Discrete-time uses the configured time-period duration and distributed-time determines the
time-points and consequently the time-periods with non-uniform durations from the start, begin and
end-times found in the dynamic model data.

Index Data
Index data are computed by the IMPL Modeler and are used to convert names to numbers during the
creation or generation of our IMPL sets, lists, parameters, formulas, variables and constraints. These
indices can also be used to reference, address, point, key or index to any of model and solution data
using the IMPL Server routines IMPLrow(), IMPLreview1()/ IMPLreview2() and IMPLrevise1()/

24. IMPLrevise2() where the row routine determines the row-element index in the IMPL sets, list,
parameter, formula, variable and constraint vectors and the revise routines can be used to update or
modify any of their row-element values if required. If the INNON (Integer Non-Naturally Occurring
Number) is returned then the unit-operation-port-state name and/or quality name was not recognized.
