SELECTION AND USE OF CONTROL CARDS FOR CONSTRUCTION

Abstract

It is proposed to use methods of statistical process control (SPC) to estimate the parameters of construction and management. In addition to the widespread Shewhart maps, we consider cases of the need to use other means of control, namely: Hotelling maps (when detecting correlations between the studied process parameters), maps of accumulated amounts (CUSUM-maps are used to detect small gradual shifts and deviations from average process values), moving average map (MA-map and EWMA-map - used to detect small trends in the development of the process), regression control maps (RK maps - allow you to detect observations that deviate greatly from average sample), Pareto control charts (used to identify the factors that most affect the change in the qualities of the studied parameter). The algorithm of the choice of control cards for estimation of parameters of construction depending on the purposes of the control and qualities of the estimated indicators is resulted
