In Korea small - medium companies constitute 96.6% of all of the mining and manufacturing industries, about 35.2% of the total production of value added business, an average of 35% of the actual export of industrial goods,and 47.7% of employment at the end of 1979. Now then small - medium industry companies organization style constitutes 82.1% of private companies and 82.7% of the total on an small scale under 50 persons in regular empolyees. Small - medium industry Companies have growing problems and bottle-necks in their physical conditions. Total Quality Control is contributed by small - medium industry company for more growth than present conditions. But now, Small - medium industry company do not use systematic application of Quality Control Method, the small - medium business compay products quality is not better as compared with big business Company. Specially, TQC is needed for Small - medium company for imperishable enlargement.

Box-Jenkins models have some important limitations to the procedure : (a) They require a great deal of time, efforts and expertise for the model identification. (b) They require an extensive amount of past observations to identify an acceptable model. (c) The model selected is a constant model in time. Therefore, the Kalman Filter is recommended as a technique to overcome the three problems mentioned above. The research reported here uses the Kalman Filter algorithm to propose Kalman-AR(p) model. The data analysis shows that the Kalman-AR(p) model proposed can be used to resolve the problems of Box-Jenkins AR(p)model. It is seen that the Kalman Filter has great potentials for real-time industrial applications.

6시그마($\sigma$)의 통계적의미는 에러나 불량률관리에서 3.4 ppm (Parts Per Milli- on)수준의 QC기법과는 근본적으로 추진목표와 그 철학적인 이론배경이 다르기 때문이다.
