    MINIMIZATION OF RISK OF THE ERRONEOUS DECISION IN THE ASSESSMENT OF THE IMPORTANCE OF STATISTICAL RELATIONS OF TECHNICAL AND ECONOMIC INDICATORS OF THE OBJECTS OF ELECTRIC POWER SY... by E. M. Farhadzadeh, A. Z. Muradaliyev, Yu. Z. Farzaliyev, T. K. Rafiyeva, S. A. Abdullayeva

    Published 2018-05-01
    “…The novelty consists in the application of fiducial approach; the calculation of critical values are fulfilled with the aid of computer technologies of simulation of possible realizations of the correlation coefficients for the two assumptions, viz. technical and economic indicators of the independent and dependent; simulation is fulfilled with the method of solving the “inverse problem”, which enables the possible implementation of the correlation coefficients for the really dependent and independent samples of random variables at a given sample size; the developed algorithms and programs for calculation made it possible to obtain the critical values of correlation coefficients for independent and dependent samples; in conditions of the sameness of the consequences of erroneous decisions it is proposed to make a decision not based on critical value but based on the boundary values of the correlation coefficients that correspond to the minimum total risk of erroneous decisions; the exemplification of the recommendations application was made on example of technical and economic parameters of boilers of power units of 300 MWt. …”

    Accuracy Evaluation of Multi-Source Precipitation Data in Mountain Flood Simulation in Guoning Village, Xiahe County by Wubin HUANG, Jing FU, Runxia GUO, Junxia ZHANG, Yu LEI

    Published 2025-02-01
    “…From 22:00 on September 6, 2023 to 04:00 (Beijing Time) on September 7, Xiahe County in Gansu Province experienced severe convective weather, with short-term heavy rainfall in some areas, causing flash floods in Guoning Village, Xiahe County, resulting in casualties.In this study, the characteristics of Radar Quantitative Precipitation Estimation (Radar-QPE), FengYun 4B Quantitative Precipitation Estimation (FY4B-QPE), and CMA Multi-source Precipitation Analysis (CMPA) precipitation products were contrastive analyzed based on meteorological station observations.These precipitation data were used to drive the hydrodynamic hydrological model and evaluate the effect of different precipitation data in the flash flood simulation.The results showed that: (1) Among the 12-hour cumulative precipitation amounts, CMPA demonstrated higher accuracy in terms of the position of large value areas and differences in local precipitation levels; Radar-QPE was closer to AWS (Automatic Weather Station) in terms of cumulative precipitation level but showed significant differences in spatial distribution; FY4B-QPE overestimated the cumulative precipitation level by 33.8%.(2) In terms of hourly distribution, CMPA was most similar to AWS in terms of temporal evolution, spatial distribution, and precipitation level; Radar-QPE's peak values were smaller, and the peak times were lagged, with negative deviations in precipitation being dominant; FY4B-QPE's peak values and peak times were consistent with reality, but there were deviations in the start and end times of precipitation, with positive deviations in precipitation being dominant.(3) In the hydrological simulation study, CMPA, Radar-QPE, and FY4B-QPE all overestimated water levels, but the timing of water level peaks was more consistent with AWS.CMPA performed best in terms of RMSE (Root Mean Square Error), NSE (Nash Efficiency Coefficient), and Bias (Relative Deviation), followed by Radar-QPE, and FY4B-QPE performed relatively poorly.Although existing site-observed precipitation cannot fully meet the needs of research and early warning for small and medium scale mountain floods, the high precision of CMPA data could effectively supplement the deficiencies of traditional meteorological observation stations to some extent.Meanwhile, the algorithms and accuracy of Radar-QPE and FY4B-QPE needed to be further improved and enhanced.…”
