a new method is developed for a fast identification of the stability situation of industrial processes. the proposed method includes two factor ratios of the control constants for the upper and lower control limits to process these constants. an indication ratio is then defined as the ratio of the maximum data range value to the difference between the maximum and average values for individual d...

in today's business environment in which coordination and adaptation with constant changes are the only ways of survival, real-time monitoring of activities and making the decisions accordingly are necessary. since performance measurement cannot be managed independent of business processes, business activity monitoring (bam) systems should monitor performance metrics based on business processes...

in some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile. in this paper, polynomial profiles are considered to monitor processes in which there is a first order autoregressive relation between the error terms in each profile. a remedi...

در بعضی از مسایل کنترل فرآیند آماری عملکرد فرآیند یا کیفیت محصول بوسیله رابطه بین یک متغیر پاسخ و یک یا چند متغیر مستقل توصیف می شود که محققان این رابطه را پروفایل می نامند. در بعضی از کاربردها همچون کالیبراسیون این رابطه بااستفاده از یک مدل رگرسیون خطی ساده توصیف می شود در حالی که در موقعیتهای دیگر مدلهای پیچیده تری نیاز است. به عنوان مثال در فرآیند ساخت موتور در صنعت خودروسازی کیفیت یک موتور ...

in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

The objective of the current paper is to present an intelligent system for complex process monitoring, based on artificial intelligence technologies. This system aims to realize with success all the complex process monitoring tasks that are: detection, diagnosis, identification and reconfiguration. For this purpose, the development of a multi-agent system that combines multiple intelligences su...
