The prediction of the occurrence of failure events for pressure vessels used in the process industry is a newly developing technology in the field of modern technical management of facilities. It is of great significance for ensuring safe and high efficiency operations in modernized large-scale and high parameter facilities of chemical, petrochemical, nuclear and electric power plants. Approximate and plausible reasonings have been proposed in the present methodology as the main procedure for drawing conclusions from hypotheses or facts involving uncertain parameters of fuzziness. In this study, a series of new techniques for predicting failure probability, gravity of perniciousness of failure events, damage to structural materials and remaining life, etc., have been developed. These techniques have met with success and have obtained economic benefits. A brief statement of theoretical work and actual case studies is given.
