✦ Synopsis

Practical problems solved by the simulation calculations of complex chemical processes require admitting a more general distribution of given and unknown input parameters of streams and nodes, than it is usual for common forward or backward "node by node" computations. The distribution should not be limited, anyway. However, for arbitrary distribution the problem of over-and underdetermination arises, similarly as in the case of balance calculations. An algorithm for testing of overand underdetermination in problem formulations for simple method of simulation calculations is derived by the application of least-square method. But the main idea can be applied also on more sophisticated methods of system engineering. The subject is closely connected with degrees of freedom of a complex chemical process.
