ABSTRACT
The SOSIE (Simulation and Optimization of Integrated Systems) software was designed to facilitate the construction of simulation models of the operation of complex production structures. Its initial versions which focused on the optimization of multi-energy systems, were not easily convertible to other purposes. It was then written in a more general fashion, enabling it to be used to describe any system (modifiable at will, both in their structure and in their management), at the same time as real libraries of complex dataprocessing items were built up (sets of sub-programs, images, data, etc.) transportable without from one model to another. Functions such as management stocking operations, transfers or conversion of products, all subject to the same software treatment, may thus be described once for all, entered into libraries, and retrieved in the various models as often as necessary. The same thing may be done with the associations of converters, to simulate complex functions such as dams, networks, factories, etc.
