A steady-state system simulator has been developed, capable of simulating the performance of a wide variety of systems. One of the most interesting applications of this systems simulator is the analysis of performance of steam and electrical power generating plants when their performance and mode of operation is closely related to the operation of a process plant. An interesting feature of the simulator is the fact that all the information is handled by a Data Base Management System. Another novel feature is the fact that the system modules can be solved for a wide variety of input information. Solving modules for the available input information rather than the customary physical input-output fashion, allows in most cases of interest to solve the network using a resolution sequence without cycles or iterations. The drawback of this approach is the fact that modules are no longer naturally inserted using the output of one module as the input of another. To solve this problem, an ordering algorithm was developed that searches for a cycleless resolution sequence taking into account the different modes of resolution of the modules. © 1989.
