Fedorenko M. The increase of the fire prevention system effectiveness of the gas processing plant

The thesis is devoted to the effectiveness increase of the Fire Prevention subsystem of the Fire Safety Supporting System (FP FSSS) of the gas processing plant by means of its parameter optimization. It is shown that FP FSSS of the gas processing plant is a complex system. And to evaluate its operating effectiveness the number of partial criteria has been entered. On the grounds of those criteria the integral criterion, which takes into consideration the Fire Safety level (FS) was developed. The optimization mathematical model was constructed and the problem of optimization of the FP FSSS of the gas processing plant at all stages of the life cycle was defined. The parameters of the defined optimization problem are determined. The value of the partial criteria was calculated. The weight coefficient of the partial criteria that specify their influence on the FS level of the gas processing plant, on the grounds of the expert estimation using the hierarchy analysis method is evaluated. The problem of optimization of the FP FSSS of the gas processing plant was decomposed into two interdependent subproblems, which correspond with the stages of discovering the existent FSSS and its removal. For working out the defined optimization problems the modification of the branches and boundaries method, that takes into a count their peculiarities, is suggested. Numerous research of the FP FSSS optimization model was conducted at the units of the Gnedyntsevsky gas processing plant in Chernihov region. Also the comparative analysis of the FP FSSS units operating effectiveness at all stages of the life cycle when using the developed optimization models and in accordance with the operating plan of the SFI (State Fire Inspection) organ was carried out. The scheme for constructing the subsystem for SFI automated workplace for increasing the operating effectiveness of the FP FSSS at the gas processing plant, its algorithmic and software support has been developed.
