Linear local tangent space alignment (LLTSA) is an unsupervised dimension reduction method, which will lends to remaining overlaps between faults when it is used to high-dimension fault feature for dimension reduction due to its incapacity of using part sample class label information. Aiming at this problem, semi-supervised linear local tangent space alignment (SS-LLTSA) dimension reduction method is proposed in this paper. In SS-LLTSA, the distance between different points is adjusted by utilizing part class label information, thereby a new distance matrix is formed and the neighborhood is construct through this new distance matrix. The improved method realized the combination of data intrinsic manifold structure and class label information, and more discriminative low-dimension features can been obtained. And then, the corresponding relationship between low-dimension feature and fault classes are established by using support vector machine (SVM). Dimension reduction with SS-LLTSA can effectively increase the discrimination of fault feature, and furthermore, SVM can further improve fault diagnosis accuracy with its excellent pattern recognition capacity. Finally, the effectiveness of the proposed method was verified through the fault diagnosis experiment of rolling bearing. © 2017, Editorial Department of JOURNAL OF MECHANICAL STRENGTH.

abs Similar to the CUSUM location chart, the traditional CUSUM dispersion chart can be designed to optimize the detection of specified variance changes. However, this optimality property requires that the magnitude of the out-of-control variance is known exactly a priori. To get away from this requirement, this paper suggests an adaptive CUSUM procedure for signaling changes in the process variance of unknown sizes. The basic idea is to first estimate the current process variance and then dynamically adjust the CUSUM chart to match the variance estimate. A two-dimensional Markov chain model is developed to analyze the chart performance. The comparison results with the traditional CUSUM dispersion chart and other competitive procedures favor the proposed one.

Overall Equipment Effectiveness (OEE) is an indicator frequently used for measuring efficiency of critical equipment. Typically presents a negative asymmetrical distribution, limited to the interval [0;1]. Due to this characteristic, it is uncommon using statistical control procedures for monitoring OEE. This study aims to contribute to this discussion by presenting an approach for monitoring OEE through statistical control procedures. The OEE/TEEP control chart is presented with sensitization procedures, allowing the user to adapt the results of the monitoring process to the needs of the monitored resource constraint. Performance results are presented based on an extensive Monte Carlo simulation study, with 4551 sets of 20 thousand observations each. One application example is also presented, for illustrating the potential of the proposed control charts.

Establishing new paradigms, such as S-BPM, requires education. In this paper, an educational proposal is developed, not only to help members of existing BPM communities shifting, but also capturing the dynamics of the field itself. The approach is grounded on the concepts of evidence-based practice and learning, stemming from medicine, and epistemological considerations. In the paper the major constituents of evidence-based S-BPM education are discussed and exemplified: provision of knowledge and content generation, exploration and consolidation, sharing and distribution. They can be intertwined and designed in a variety of ways. Of particular interest are stakeholder-specific perspectives and behavior patterns, as the change over time, and require sophisticated features and a corresponding scheme of representing BPM content, information about user-specific content individualization, and social interaction. © 2011 Springer-Verlag.

Intelligent advisory services are becoming increasingly pervasive. Ranging from e-Commerce to e-Government platforms, intelligent advisory systems, with user-centered design, can potentially overcome technical barriers that commonly exist on traditional websites. This study explores the impact of system-user communication style similarities on the user's perception towards the virtual advisory service in the healthcare domain. Drawing on Similarity-Attraction Theory, we propose a research framework to investigate this relationship. Through a mixed-method approach, including preliminary surveys, experiments and follow-up interviews, this study shows that an intelligent advisory system's communication style, when aligned well with a user's communication style, can better engage the user and lead to more perceived transparency, enjoyment, informativeness and credibility during the interaction process. Overall, hedonic aspects of user perceptions are shown to be more critical for creating a feeling of social presence and reuse intentions than utilitarian ones. The implications of the study for research and practice are then discussed. © 2014 Elsevier Ltd.

Information systems and information technology (IS/IT, hereafter just IT) strategies usually depend on a business strategy. The alignment of both strategies improves their strategic plans. From an external perspective, business and IT alignment is the extent to which the IT strategy enables and drives the business strategy. This article reviews strategic alignment between business and IT, and proposes the use of enterprise engineering (EE) to achieve this alignment. The EE approach facilitates the definition of a formal dialog in the alignment design. In relation to this, new building blocks and life-cycle phases have been defined for their use in an enterprise architecture context. This proposal has been adopted in a critical process of a ceramic tile company for the purpose of aligning a strategic business plan and IT strategy, which are essential to support this process. © 2011 Taylor & Francis.

Recently, much attention has been given to performance management within collaborative environments resulting in a wide variety of performance measurement/management frameworks. However, practically all of these frameworks present a common gap regarding the information treatment needs that support these frameworks. This issue is even more important in the case of Small and Medium-sized Enterprises (SMEs) due to their special characteristics. For that purpose, this paper presents an approach called Global Performance Management (GPM) Framework composed of a methodology, an information architecture and a technological solution, focusing mainly on the information architecture. The methodology guides SMEs when defining, developing, deploying and operating the GPM framework. The information architecture consists of a set of elements that support the tasks of collection, treatment and analysis of the used information, which complement the methodology to build a real model for the GPM framework. Finally, the technological solution bridges the engineering and conceptual environment, with the real-world operational and executable environment, following the path defined by the methodology. The information architecture was applied to two European pilots, achieving satisfactory results, which are highlighted in the paper as well as the main barriers encountered and solutions provided. © 2010 Elsevier B.V.

Preventive methods are seldom used in logistics, although there is increasing awareness of their potential. This paper presents two examples of preventive methods currently in use, Poka-Yoke and FMEA (Failure Mode and Effect Analysis). The implementation of Poka-Yoke, the mistake proofing methodology, has been shown to drastically reduce the enormous warranty costs, including logistics costs, while FMEA, implemented for the purpose of assuring the smooth execution of industrial processes, has already been successfully applied during the early planning phase of a new packing centre under construction.

Subject-oriented Business Process Management (S-BPM) is a novel paradigm in Business Process Management (BPM). Educating students and business stakeholders in S-BPM requires facilitating a substantial mind shift from function- towards communication-oriented (re-)construction of processes. Reformist pedagogy, as driven by Maria Montessori, allows learners grasping and applying novel concepts in self-contained settings and in an individualistic while reflected way. So why not learn from her experiences for introducing S-BPM? In this contribution her analysis of human cultural factors enabling literacy has been transcribed to S-BPM education. When informing S-BPM capacity development according to progressive education, understanding the actual situation and readiness of learners seems to play a crucial role, as it influences their engagement in learning environments. These factors need to be differentiated when conveying S-BPM concepts and activities. © 2014 Springer International Publishing.
