Safety-oriented global analysis and parallel processing
The objective of safety-oriented global analysis (SOGA) is to determine the conditions under which the evolution of a dynamic system in time remains within the imposed constraints in view of the uncertainties on the system parameters and/or the observed systern state. Often the only generally applicable SOGA method for nonlinear systems is the direct integration of the governing equations, which can be computationally prohibitive. An alternative SOGA methodology has been under dridopment at the Ohio State University (OSU), and its application to reactor dynamics has been illustrated in previous presentations. In spite of the computational advantage of the OSU methodology over direct integration, the computational time and storage requirements are still limiting factors in implementation. A procedure to reduce the storage requirements was presented earlier. This paper describes how the computational time can be reduced using parallel processing.
