The universe of methodology for predicting the damage to structural materials and remaining life of process equipment is a branch of subject of a newly developing discipline - FORECASTING. The technique for predicting the damage to structural materials and remaining life of process equipment based on the use of experience of multi-discipline is a comprehensive technology in the field of modern technical management of facilities. Some contents of this technique have been selected among the subjects of emerging technologies to be developed over this century.

In this study, a series of new techniques for predicting the damage to structural materials and remaining life of porcess equipment have been developed, which are based on principles of approximate and plausible reasonings for uncertain parameters of fuzziness by fuzzy set theory; of quantitative metallographic technique by methods of stereoscopy and visual treatment technique.The technique proposed is of great significances for ensuring safe, high efficiency and long period operations in modernized large-scale and high parameter facilities of chemical, petrochemical, nuclear and electric power plants.

The main contributions of the technique proposed in this work are on engineering applications which provide major benefits in economics and society. The technique will be a bright future in use.
