Ecological Systems and Devices Annotation << Back PROCESS MONITORING OF WASTEWATER TREATMENT IN THE PRODUCTION OF PRINTED CIRCUIT BOARDS TAKING INTO ACCOUNT CORRELATION OF INDICATORS V.N. Klyachkin, Z.V. Podolskaya, K.S. Shirkunova Statistical process control methods in monitoring of wastewater treatment in the production of printed-circuit boards allow you to detect violation of stability and on time to prevent controlled output indicators for the maximum permissible value. In the context of correlativeness uses multidimensional indicators methods based on Hotelling’s algorithm, you must also identify the indicator or indicators group responsible for violation of process.
