In the article we concentrate on timing aspect of information propagation on social web. The aim of the information producer is to transfer the information to the broad audience via social web. Producer needs to identify interesting content and publish it to social web in the right time. Right timing of information publishing can increase the potential of spreading it. In the article we describe the process of interesting content identification and we present a model for right moment estimation of information publishing. Our estimation is based on producer's web usage mining, web topic tracking and event identification.

Along with the service sector plays a more critical role in the development of world economy, conventional manufacturer puts more focus on bundling service with physical products to gain competitive advantage. Based on the traditional theory of supply chain management, this paper proposes Service Supply Chain to cover the supply chains for both service industry and manufacturing industry. Then a Product-Service Matrix is established to reveal the nature of the service supply chain. A Servitization-Globalization Matrix is developed to describe the evolution footprint from conventional manufacturing factory to Global Service Network and Global Manufacturing Network. Finally, this paper establishes a conceptual framework for service supply chain management, and the management processes are proposed and compared with other model.

To evaluate the soundness of multidimensional binary signal analysis based on Boolean factor analysis theory and mainly of its neural network implementation, proposed is a universal measure - informational gain. This measure is derived using classical informational theory results. Neural network based Boolean factor analysis method efficiency is demonstrated using this measure, both when applied to Bars Problem benchmark data and to real textual data. It is shown that when applied to the well defined Bars Problem data, Boolean factor analysis provides informational gain close to its maximum, i.e. the latent structure of the testing images data was revealed with the maximal accuracy. For scientific origin real textual data the informational gain provided by the method happened to be much higher comparing to that based on human experts proposal.

Procurement and replenishment are always susceptible to uncertain customer demand and also to purchase price volatility. Single factor approaches such as long-term contracts, spot procurements, or supply contracts with options, can mitigate some specific aspect of the overall risk, but such approaches are often of limited value when several types of risk prevail. This study contributes to the problem of procurement by presenting a portfolio approach that simultaneously deals with the two major types of procurement risk, price and inventory. The specific model presented jointly considers both the procurement planning and risk hedging problems. The model is in the form of a multi-stage stochastic program in which replenishment decisions are made at various stages along a time horizon, with replenishment quantities being jointly determined by the stochastic demand and the price dynamics of the spot market. The model attempts to minimise the risk exposure of procurement decisions measured as conditional value-at-risk. Numerical experiments to test the effectiveness of the proposed model. The results indicate that the proposed model can fairly reliably outperform other approaches, especially when either the demand and/or prices exhibit significant variability.

The development of Large Vocabulary Continuous Speech Recognition systems involves issues as: Acoustic Phonetic Decoding, Language Modelling or the development of appropriated Language Resources. In the state of the art, new techniques for reusing Language Resources of more resourced related languages is becoming of great interest, and there is also a growing interest on Multilingual systems. This paper describes the initial experiments on multilingual recognition and cross-lingual adaptation carried out in order to create a robust Multilingual Speech Recognition system for the Basque context. The interest on Multilingual Systems arouses because there are three official languages in the Basque Country (Basque, Spanish, and French), and there is much linguistic interaction among them, even if Basque has very different roots than the other two languages.

Laser trackers have been widely used in many industries to meet increasingly high accuracy requirements. In laser tracker measurement, it is complex and difficult to perform an accurate error analysis and uncertainty evaluation. This paper firstly reviews the working principle of single beam laser trackers and state-of-the-art of key technologies from both industrial and academic efforts, followed by a comprehensive analysis of uncertainty sources. A generic laser tracker modelling method is formulated and the framework of the virtual tracker is proposed. The VLS can be used for measurement planning, measurement accuracy optimization and uncertainty evaluation. The completed virtual laser tracking system should take all the uncertainty sources affecting coordinate measurement into consideration and establish an uncertainty model which will behave in an identical way to the real system.

The paper presents the results of the authors' studies which consisted in modeling the processes taking place in an enterprise characterized by manufacturing of complex products (machine building) of a very long production cycle. The production environment of a diesel ship engine is described. The idea of the so-called domains of the CIMOSA concept which has been used for the modeling was explained. The article introduces the multi-agent system idea on the basis of which a model will be built and used in the simulation experiment. Finally the algorithm for planning process is presented.

Maritime surveillance is a difficult task as its aim is to detect any threatening event in a dynamic, complex and hugely distributed system. As there are many different types of vessels, behaviours, situations, and because the system is constantly evolving, classical automated surveillance approaches are unrealistic. We propose an adaptive multi-agent system in which each agent is responsible for a vessel. This agent perceives local anomalies and combines them to maintain a criticality value, used to decide when an alert is appropriate. The importance of the anomalies and how they are combined emerges from a cooperative self-adjusting process taking user feedback into account. This software is currently under development in ScanMaris, a project supported by the French National Research Agency.

This paper presents an evaluation method for part manufacturability. The data model used is the STEP-NC data model, i.e. ISO 14649. Firstly, the evaluation indices such as workpiece clamping, performance of machine tools, resources of cutting tools and auxiliary performances are presented. Then, an information resource model of machine tools is established, and an evaluation algorithm is designed. Finally, a prototype system is discussed which verified the model and algorithm developed.

Manufacturing cost reduction, product quality improvement, training, new product introduction, and cycle time fluctuation are common challenges for semiconductor assembly and test manufacturing (ATM) factories. Manufacturing Execution System (MES) as the bridge connecting Enterprise Resource Planning (ERP) and Process Control System (PCS) is essential for manufacturing to collect real-time product line information, support manufacturing decision making/scheduling and increase manufacturing efficiency. This paper will present the operational complexities that are integrated into the MES solution. Based on the special features of ATM and data warehouse technology, the MES architecture has been designed with four layers of integrated automation system including basic functions, data layer, business objects/methods and user interface. As the MES adopting this approach turns into reality, overall manufacturing competition advantage and production process management improve greatly. Furthermore, this system has been applied to all Intel ATM factories. The successful implementation of this system has explored a new approach for the high volume manufacturing systems in discrete manufacturing enterprise.
