Monitoring Heterogeneous Multivariate Profiles Based on Heterogeneous Graphical Model
نویسندگان
چکیده
Process monitoring using profile data remains an important and challenging problem in various manufacturing industries. Motivated by application case of motherboard testing processes, we develop a novel modeling framework for heterogeneous multivariate profiles. In this framework, graphical model is constructed to depict the complicated relationship among channels. Then channels can be reduced networks. Besides, investigate several theoretical results concerning accuracy estimated structure. Finally, demonstrate proposed method through extensive simulations real study.

Investigating Effect of Autocorrelation on Monitoring Multivariate Linear Profiles
Abstract Profile monitoring in statistical quality control has attracted attention of many researchers recently. A profile is a function between response variables and one or more independent variables. There have been only a limited number of researches on monitoring multivariate profiles. Indeed, monitoring correlated multivariate profiles is a new subject in the fileld of statistical proces...
متن کاملmortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولA dynamic lattice model for heterogeneous materials
In this paper, the mechanical behavior of three-phase inhomogeneous materials is modeled using the meso-scale model with lattice beams for static and dynamic analyses. The Timoshenko beam theory is applied instead of the classical Euler-Bernoulli beam theory and the mechanical properties of lattice beam connection are derived based on the continuum medium using the non-local continuum theory. T...

The diffusion of Web-based multimedia services and the emerging competition among service providers require to enrich the Internet infrastructure with mechanisms to manage and control service quality and availability. These goals require monitoring mechanisms that ascertain the state of resources and applications in the global distributed system, and that should be a core functionality of any i...
متن کاملEvent Monitoring Based On Web Services for Heterogeneous Event Sources
This article discusses event monitoring options for heterogeneous event sources as they are given in nowadays heterogeneous distributed information systems. It follows the central assumption, that a fully generic event monitoring solution cannot provide complete support for event monitoring; instead, event source specific semantics such as certain event types or support for certain event monito...
