The Definition of the Language
LPL is not a commercial system which needs to compete with other systems. The language is relatively simple and small. There are three reasons why LPL has been developed. In the mid-eighties, when the LPL project began, there were virtually no modeling tools available for personal computers. Yet, people at our Institute of Informatics had to manage real-life, large models. LPL and other tools have been developed and have been used since for this purpose. The second reason was to have computer-based tools for teaching modeling in operations research. I always found it to be an anachronism to teach modeling in OR without a computer. After all, wasn’t OR a child of the advent of computers?
