This paper deals with the 3-co mponent identical system under the influence of hu man errors and Co mmon Cause Shock (CCS) failures. The M L estimates of system availability and frequency of failures were developed in the case of series and parallel systems. Also we developed empirical evidence to establish the valid ity of the proposed estimates by simu lation study. have complementary exponential distributions. Dhillon[5] discussed the role o f CCS failures and hu man errors in estimating reliability of a system. Sagar et al[8] developed the reliability and availability measures in the presence of CCS failures and human errors. He considered three component identical system.This paper presents, Maximu m likelihood estimat ion approach to assess the performance of the redundant systems. In this connection, we considered three co mponent identical system which is affected by human erro rs and Co mmon cause shock failures. The M L estimates are proposed for reliability indices such as availability function, frequency of failure function in the case of series and parallel systems. Also the proposed estimates are assessed based on simulated samples.

The present paper discusses the problem of estimating the reliability measures of a three-component identical system when the system is affected by Common Cause Shock (CCS) failures as well as human errors. The maximum likelihood estimators of the reliability measures like reliability function and mean time between failures of the present model are obtained. The performances of the proposed estimates have been developed in terms of mean square error, using simulated data. General TermsThree-component identical system, Reliability measures, Reliability estimates, Maximum likelihood estimation.

2014) The evaluation model of international science and technology cooperation based on set pair analysis, Journal of Interdisciplinary Mathematics, 17:1, 95-108, AbstractThis article studied the situation of international scientifi c and technological cooperation use the set pair analysis after understanding the research status of the international scientifi c and technological cooperation. Firstly we introduces the basics of set pair analysis, Secondly we established evaluation indexes and model of international science and technology cooperation based on set pair analysis, At the same time, we analyze the cooperation that China and other six countries, and obtain the corresponding conclusions by the system's situation of connect number in set pair analysis, putting forward strategy and suggestion that can promote international scientifi c and technological cooperation.
