Статистическое управление процессом (SPC)
Dear sirs carmakers, car components producers,
mechanic engineers and plastic and elastomers producers! System approach to the
quality management urge companies to analyze consumers demands and determine
Key Product Characteristics contributing good quality acceptable for the
consumers as well as keep the processes in work on the basis of SPC
(Statistical Process Control). Thanks to efficient software we can make quick
and successful introduction of statistic process control. There is a database
keeping all the measurement on the process characteristics and initial
components. It helps avoid defective products and makes possible the prototype
search in the quality sector: develop formula and construction of the product
using calculation and without expensive lab evaluation. Modern computer
evaluation programs SPC run CR, Cp, CPK, PR,PPK calculations, make diagrams,
histograms, n,p,c,r schemes for sheer seconds. I offer You my service on
creating computer programs and SPC&MSA data base.
1. SPC computer programs are needed for:
-statistic acceptance test in all kindsof production and construction;
-certificate centers auditors to evaluate providers;
-product consumers to carry homologation of initial components (in production sector, construction and pharmacology)
-in research centers to access agricultural products and food.
2. MSA Computer programs. In production
control poor assessing system may entail false conclusions and excessive
process regulation With MSA we can assess the product characteristics and
process with no risk at all.
MSA includes the following definitions:
-minimum grade value;
All programs have clear and convenient interface and laconic graphic analyses. According to Key Control Characteristics (KCC) the process control is a parameter of process (such as temperature, speed, pressure, calibre, the size etc.) where the disorder should be maintained in the established limits (borders of certain limits by production schedules) for keeping or minimization of disorder of the key characteristic of a product within its limiting values.
Key Product Characteristic (KPC) is the product characteristic where reasonably expected disorder can affect safety of a product, compliance to requirements of standards or norms or satisfaction of the product consumer. All analyzed key characteristics of KPC of car components (Key Product Characteristics) should be located in the PPAP folder.
