Decision Support Method for Efficient Sequential and Parallel Simulation: Time Decomposition in Modified Conceptual Models

A new method, the time decomposition in modified conceptual models (MCM) is described. There are introduced two approaches to model the function execution time in MCMs, necessary to decomposition: the execution-state approach and the execution-path approach. There are also described transformations necessary to manage the resolution of MCMs. There is also introduced the concept of preliminary simulation to the time decomposition of MCMs in process simulation environment. There is given an example of using decomposition results to support sequential-parallel simulation decisions increasing the efficiency of simulation.
