Applicability of Weibull distribution in Generating Model for Evaluating Lifespan Closed Circuit Television System (CCTV)

Abstract CCTV is an expedient tool for monitoring and investigating. Since it can record emergency routine events in memory of the electronic circuit board. However, process operating CCTV, necessary to carry out a sampling inspection on its lifetime predicate availability reliability. According previous literature, most parameter estimation methods used only one method, which not sufficient identifying two explicit parameters Weibull distribution. Moreover, bad method cannot achieve reliable analysis results. Therefore, this paper presented four both graphical analytical estimating These have measured accuracy by using mean square error (MSE). In addition, real data set confirmed that there distribution Kolmogorov-Smirnov test. The simulation results found maximum likelihood (MLM) outperform other estimator because provide minimum MSE, optimal shape 4.3881 scale 86.8207. Finally, are applied sets CCTV. As result, fits with sets, evaluate lifespan time failure (MTTF) as 6.6 years.
