To solve the implementation problems of knowledge management when a product is designed in Reverse Engineering (RE) integrated system developed by Multi-Agent, knowledge representation analysis involved in the process of reverse design is firstly analyzed. The tree architecture of knowledge is built. Three kinds of knowledge including domain and cooperation and meta-level are categorized according to analysis. The function process of knowledge management is then classified into three stages including collection, organization and application. By coordinating relationships among knowledge, data, process and tool, a comprehensive decision support system is finally constructed based on knowledge integration. The system possesses characteristics of cooperation and intelligence;it can support the distributed integration development environment in reversely designing process.

Measurement system configuration or deployment is becoming an important issue in the technique field of large volume metrology. Almost all configuration works are task-specific and heavily rely on time-consuming and labor-intensive experiment on shop-floor. Furthermore, such configuration way is difficult to be carried out in the early stages (product and process design) of large complex product development because it is not based on the direct product model. Therefore, there is a strong need to establish optimal configuration model and to perform configuration simulation before the implementation of actual physical deployments or setups on shop-floor (online). This paper firstly presents a problem definition and a classification scheme for large-scale measurement system. Then a general framework and main procedures for measurement system configuration are proposed. The general framework is consisted of four tasks: (1) select instruments, (2) solve feasible space domain, (3) simulate measurement points, and (4) estimate and visualize uncertainty. The rough configuration performs the former two tasks to maximize the accessible volume, while the fine configuration conducts the latter two tasks to minimize the measurement uncertainty. Main algorithms involved with the procedures in the measurement system configuration are identified. A CAD-directed prototype for measurement system configuration has been developed to identify the suitable deployment solution for specific measurement task. An initial experiment study of a wing rib of airplane has demonstrated the effectiveness of the framework and methodologies.

Energy efficiency represents one of the main challenges in the engineering field. The benefit of the energy efficiency is twofold: the reduction of the cost owing to the energy consumption and the reduction in the energy consumption due to a better design minimising the energy losses. This is particularly true in real world processes in the industry or in business, where the elements involved may be considered as distributed agents. Moreover, in some fields like building management systems the data are full of noise and biases, and the emergence of new technologies -as the ambient intelligence can be- degrades the quality data introducing linguistic values. In this contribution we propose the use of the novel genetic fuzzy system approach to obtain classifiers and models able to manage low quality data to improve the enemy efficiency in intelligent distributed systems. We will introduce the problem and some of the challenging fields are to be detailed. Finally, a brief review of methods considering the low quality data is related.

The development of intelligent Tutoring Systems (ITS) based on mobile platforms offers new perspectives for a better integration of people with intellectual disabilities. The LAGUNTXO System aims to achieve the performance of human tutors. Due to the wide diversity related to a person with disabilities, an intelligent structure that may achieve a convenient tutoring system configuration for each case has been incorporated. With an appropriate design of the structure and architecture of this task handler, it is very easy to operate by stakeholders. An automaton-based mechanism has been performed to technologically adapt the large amount of possibilities related to the interaction between people with disabilities, the task that is going to be made autonomously by users, and the mobile system elements. In this paper, LAGUNTXO architecture, operational ways, heuristic evaluation and a pilot study with final users are presented.

Globalization has resulted in a dynamic environment which is a combination of uncertainties and unpredictable behaviour of customers, enterprise partners and market conditions. As a consequence, manufacturing enterprises tend to improve the monitoring and control of enterprise value creation processes to achieve flexibility and adaptability. Enterprise integration (EI) can be seen as a prerequisite for realizing a multi-loop control system within and across different enterprise levels. Various standards are available for El but these standards do not mention how to realize them in terms of technology. Therefore, an IT-framework for digital El based on different standards and technologies is proposed. This IT-framework describes integration of manufacturing level and enterprise control level, graphical user interface for visualization and control, and process control using workflow management system and rule-based system. Finally, a case study is presented showing the application of the IT-framework for different types of manufacturing.

This article presents the Hippocrates of Cos Multi-Agent System 1.0 (HC-MAS 1.0) a multi-agent system (MAS) based on PAINALLI, an open MAS architecture based on virtual organizations. PAINALLI utilizes an agent-based model to facilitate the development of MAS and optimize the communication process in business organizations. The architecture and the system can access information and services ubiquitously from either land or mobile devices connected to wired or wireless networks. HC-MAS 1.0 supports the communication process for the healthcare services of a hospital. This paper presents the results obtained from the implementation of the system and demonstrates the advantages produced by the use of this new technology.

Today's manufacturing plants are equipped with heterogeneous software systems for different types of tasks, both manufacturing operations and factory planning. On the operating level software systems are neither yet integrated and thus support separate tasks such as production monitoring, sequence planning, work piece identification, maintenance order management, worker information and others. Nor are MES-systems parts of the integrated industrial engineering chain from mechanical engineering, electrical engineering, PLC-programming to operations. Today information technology becomes the main enabler for new processes and structures in manufacturing and logistics. In this paper the author presents six relevant trends for MES-systems, derived from actual R&D-projects with industrial partners. The mentioned trends are illustrated by examples from projects.

This paper presents the development of a new modelling constructs enable human and technical resource system to be described coherently and explicitly as 'configurable', 're-usable' component' of manufacturing enterprise, so as to support agile dynamic manufacturing process-resource system design and decision making. These components are referred to as 'Dynamic Producer Units' or DPUs. DPU characterization is designed to facilitate: (1) Graphical Representation (2) Explicit Specification and (3) Implementation Description of Resource systems. This enable the modelling of responsive production systems;where such systems comprise user defined configurations of process networks, resource systems and time dependent flows of units of work. The new modelling methods was then applied through a case study concentrate on engine assembly, illustrated how responsive production systems could be designed by using the method, followed by discussion of future development especially the capability of computer executable within simulation modelling environments.

Discrete industry (DI) concentrates on a class of business where the production process is basically no material change except the shape and compositions. In such DI workshop, productivity is greatly obstructed by tedious information transferring and management by paper work. This paper proposes a RFID-enabled real-time paperless hardware platform for DI. First, wireless manufacturing devices such as RFID readers are deployed in DI workshop. Then, a wireless communication network is set up. Finally, real-time manufacturing could be achieved according to the reorganization of production. A case study is also introduced in this paper to illustrate how real-time manufacturing works through this platform in DI workshop. Limitations such as channel seeking and universal work flows configuration should be improved if this platform of great merits to extend to other industry.
