Chapter 15 - Appendix 2
One fundamental point with Asprova is that it can be used without the need for customization. However, we will customize a system in order to answer the special demands of plants and factories that are applying such things as scheduling logical and user interfaces. Expressions should be used in cases where items can be solved through the use of those previously mentioned expressions, but if there is a problem that cannot be solved through the use of an expression, plug-ins can be developed for that purpose using a COM interface.
Asprova's objects and properties are available to the public to be used, almost as is, via the COM interface. The user uses such things as Visual Basic, C++ and C# to develop plug-ins by means of these objects and properties.
