Enterprise application integration (EAI) has been pursued strenuously by researchers and industrial practitioners for decades. With the advent of Web Services and Service-Oriented Architecture (SOA), realizing enterprise integration, even automating inter-enterprise interactions become feasible. Virtualization is the fundamental for implementing an SOA(More)
To reduce energy consumption for sustainable and energy-efficient manufacturing, a good understanding of the dynamic energy consumption patterns on the manufacturing shop floor is essential. In this paper, we introduce a novel approach to address the challenge of missing operation context information during in-situ energy data measurement. Finite-State(More)
The wireless sensor network (WSN) has provided new paradigm for factory automation applications such as asset tracking, machinery condition monitoring and distributed equipment control. This paper will show a design framework for industrial asset tracking application using WSN. The framework will use some optimization decomposition approach to address the(More)
A hybrid system combines continuous and discrete dynamics and runs with a set of modes. In we proposed an efficient health monitoring method for hybrid systems. This method utilizes unified constraint relations, named the global analytical redundancy relations (GARRs). Using GARRs for hybrid system health monitoring requires knowledge of the system's mode(More)
We consider the problem of estimating the position of an indoor wireless transmitter. Based on Angle of Arrival (AOA) readings from several base stations, a wireless transmitter's position has traditionally been determined using a least-squares approach. In particular, care is taken to ensure that the least-squares estimator is unbiased. Unbiased estimators(More)
In this paper, generic methodologies for prognostic machinery health management are discussed and a framework is proposed for extending prognostic capabilities to conventional maintenance and diagnostic system (MDS). Two specific techniques that can be used to extract knowledge and rules for fault prediction are discussed. These techniques are based on the(More)
With the continuing trend towards globalization and focusing on high value with low volume, the manufacturing system architecture is evolving from traditional centralised model to the distributed model and to the recent networked model. In the modern manufacturing environment, the manufacturing systems are in networked framework via a variety of networking(More)
