Abstract: The automotive industry is facing new challenges from increasing product diversification, decreasing product life cycle times and the permanent need of cost reduction. The increasing complexity of products and the reduction of costs per unit determine complex manufacturing systems with high levels of automation. The product ramp-up has a crucial role for the financial success in the automotive industry. The performance of a ramp-up depends on the maturity of product and manufacturing system. The reuse of knowledge of experience is an extraordinary driver for the maturity of both product and manufacturing system. A new approach combines the Delphi-method with experience management software based on semantic web technology. The combined solution enables to reuse experience for the development of highly automated manufacturing systems and to minimise rampup risks.

Abstract: The successful execution of ramp-ups is imperative for the financial performance of companies. In 2004, almost 60 percent of all ramp-ups missed their economic targets. Currently, ramp-up costs are often insufficiently planned and controlled. This leads back to the fact that their drivers are opaque, and that methods and/or instruments supporting the planning and controlling of ramp-up costs are entirely missing. This contribution presents the requirements for a key metric system to improve the planning and control of ramp-up costs. Furthermore, we systematically demonstrate how this metric system can be built up by following a four step approach. Finally, also the benefits of using the key metric system are investigated.

Abstract: A method is presented to abstract the information required by the production shop floor control computer system to coordinate material flow and part processing. An analysis is given covering aspects identified as relevant for process modeling and automation, such as granularity degree, life cycle, BOM/route/process integration and object oriented model reference. Particularities of production system are presented in a graph model and interpretable by computer applications. Use of model based control is among the concepts used to increase the system software reusability. The proposed solution simplifies the production system (enterprise) modeling process and improves system software reusability among other characteristics.

Abstract: E-maintenance is an emerging concept generally defined as "a maintenance management concept whereby assets are monitored and managed over the Internet". Nevertheless a lot of complementary definitions exists in which are introduced the principles of collaboration, knowledge, intelligence ... A consensus is not approved and the number of references and work is huge without a unique repository to ensure consistency. Consequently the aim of this research and review note is to define more precisely the emerging concept of e-maintenance and then to propose and discuss a conceptual e-maintenance framework based on Zachman framework. Such a framework can facilitate a widespread understanding of e-maintenance and provide useful guidance for supporting e-maintenance deployment through services, processes, organisation and infrastructure. Because of this, it can be used to classify recent e-maintenance contributions.

Abstract: Today, a new role for maintenance exists to enhance the eco-efficiency of the product life cycle. The concept of "life cycle maintenance" emerged to stress this role leading to push, at the manufacturing stage, an innovative culture wherein maintenance activities become of equal importance to actual production activities. This equivalence requires mainly considering the integration of the maintenance and production strategy planning for developing opportunistic maintenance task keeping conjointly the product - production - equipment performances. In this paper, a novel approach is proposed for integrating maintenance and production planning. The approach uses the "odds algorithm" and is based upon the theory of optimal stopping. The objective is to select, among all the production stops already planned, those which will be optimal to develop maintenance tasks keeping the expected product conditions. It uses criteria such as component performance and component reliability. An approach evaluation is shown on a practical example.

Abstract: Ontology plays important role in knowledge sharing, reuse, and communication. Repository ontology is usually the first step in the development of an intelligent decision support system. This paper first briefly reviews the literature in the area and then presents the ontologies for condition monitoring and maintenance. A short description of the software application and user interface ontologies is presented. The focus of this work is the repository ontology for the stated purpose. It shows the data structure and information needed for the maintenance management of the industrial assets with its objects, attributes and relationships. The methodology that has been used consists of different steps of defining the scope of the ontology followed by the consideration of using existing ontologies. It is based on the ontology-driven Information System theories and developed by Unified Modelling Language tool.

Abstract: The E-Maintenance paradigm has potential to impact technical, environmental, personnel, and market issues in the industrial and services maintenance sectors. To this concern, advances in MEMS (Micro Electro Mechanical Systems), in wireless technology and in custom microprocessors are giving the opportunity to produce so called "smart sensors" that will be capable to get automatically maintenance information from the shop floor equipment. Using this technology, self diagnosing and self healing systems could be developed. This will allow the design of totally new maintenance management systems, through integration with prognostics and CMMS (Computer Maintenance Management System) software. The analysis of the new maintenance business models that will emerge from this technology breakthrough is an interesting research topic that this paper intends to address.

Abstract: Small and medium enterprises (SME's) have similar characteristics in developing countries. They have facilities for their administration but limited resources in manufacturing technology. In an environment in which market dynamics and production patterns are changing, enterprises try to improve their performance related to the production velocity of manufactured items with reduced costs in their operations. Under this scenario, SMEs need low cost manufacturing automation in order to be able to compete. This paper describes an architecture that allows the integration of engineering applications on a network, with emphasis in machining functions. The proposed approach is based on the Internet Communications Engine (ICE) technology for machining applications integration.

Abstract: A low-cost alternative to software development in many domains is the construction of software family infrastructures. Instead of developing one system at a time, the software families approach focuses on creating an infrastructure of software components and configuration tools to construct application systems from a specification. The approach to implement software families for constructing component-based CNC and systems has been demonstrated. However, as any other system, software family infrastructures need to be evolved to add new components or constraints to the infrastructure. This paper presents an approach for software family infrastructure evolution and its demonstration in an infrastructure for configuring a software family of CNC systems.

Abstract: The present paper focuses on the adoption of simulation for the engineering of spare parts management in multi site contexts. A simulation model based decision support system, enabling decisions in spare parts management, is presented: at first, its modelling features are described by means of Unified Modelling Language; then, a demonstration of the decision support system is presented in order to outline its functions, an industrial use case is adopted for the sake of demonstration. Eventually, the paper extends its scope to envision integration of the decision support system in a maintenance information system of a manufacturing enterprise. The vision serves in order to define the role and integration requirements of simulation within a computer aided maintenance engineering system.

Abstract: Process monitoring and control requires estimation of quality variables, which are often not measurable directly. A cost effective approach to monitor these variables in real time is to employ model based soft sensing and state estimation techniques. Dynamic model based state estimation is a rich and highly active area of research and many novel approaches have emerged over last over last few years. In this paper, we review recent developments in the area of recursive linear and nonlinear Bayesian state estimation techniques.

Abstract: This article describes the application of an Artificial Intelligence Planner in a robotized assembly cell that can be integrated to a Flexible Manufacturing System. The objective is to allow different products to be automatically assembled in a single production line with no pre-established assembly plans. The planner function is to generate action plans to the robot, in real time, from two input information: the initial state (disposition of parts of the product in line) and the final state (configuration of the assembled product).

Abstract: Manufacturing competitiveness relies on the companies' ability to rapidly reconfigure their assembly systems. This paper introduces assembly system proactivity, a concept based on interrelated levels of human involvement, automation, and information handling. Increased and structured human involvement contributes to increased system ability to proactively address predicted and unpredicted events. Correct involvement of human operators will utilize the fully combined potential of human and technical capabilities, providing cost-efficient assembly system solutions. The ProAct project is developing proactive assembly system models and evaluating proactive, feature-based solutions. Focus is on realizing the potential of cost-efficient and semi-automated systems with relevant human involvement, i.e. highly skilled operators that add flexibility and functionality.

Abstract: Standardisation initiatives (ISO and IEC) try to answer the problem of managing heterogeneous information, scattered within organizations, by formalising the knowledge related to products technical data. While the product is the centred object from which, along its life cycle, all enterprise systems, either inside a single enterprise or between cooperating networked enterprises, have a specific view, we may consider it as active as far as it participates to the decisions making by providing knowledge about itself. This paper proposes a novel approach, postulating that the product, represented by its technical data, may be considered as interoperable per se with the many applications involved in manufacturing enterprises as far as it embeds knowledge about itself, as it stores all its technical data, provided that these are embedded on a common model. The matter of this approach is to formalise of all technical data and concepts contributing to the definition of a Product Ontology, embedded into the product itself and making it interoperable with applications, minimising loss of semantics.

Abstract: Automation is rapidly evolving, having a profound impact in the way we do work. Such development and the rapid integration of automation systems into most of the engineering processes call for constant, efficient training into automation and control systems. However, this kind of equipment is very expensive, constantly limiting both universities and private companies to have training facilities that are not widely available or, definitely, to not being able to have these facilities at all. The present paper establishes a scheduling/connection scheme for real remote automation laboratories based in common automation protocols for connection, image acquisition systems, and their publication for remote access in real time, interconnecting all the elements by a server, reducing the needed space for traditional automation laboratories, the staff needed to operate it, and the overall cost of equipment required, as well as allowing the lab practices to be customizable.

Abstract: This work presents challenges and solutions for the teaching and learning of automation applied to integrated manufacturing by means of a methodological approach based on techniques, tools and industrial equipment directly applicable in the industry. The approach was implemented in a control and automation engineering course divided into expositive and laboratory classes. Since the success of the approach is mainly from the practical activities, the article focus more on activities developed in laboratory than theorical classes.

Abstract: The current solutions implanted in the majority of manufacturing systems controlled by PLCs were developed through the language of programming known as "ladder". Such a language, easily learned and handled, shows to be efficient whenever the system to be implanted does not demand greater complexity of analyses. Bigger systems, presenting characteristics in which resource compartments, parallelism and synchronizing among processes are more frequent, demand the adoption of solutions differentiation. This article presents a teaching experience and practical application of Petri nets in a Mechatronics Engineering graduation course.

Abstract: This paper shows the significance of the structural models to solve diagnosis issues for concurrent faults in large scale systems. Considering that the capability to solve a particular fault diagnosis problem is a structural property between internal and external variables of the process with redundancy, it is suggested to investigate the structural model of a process as previous work to the formulation of a fault diagnosis task. This previous study guarantees a successful residual generator task and simplifies the fault tolerance control reconfiguration issue. The generic structure of a system is analyzed in term of graph theory tools, since diverse software toolboxes are today available to straightforward handle relations between variables and their redundancy. Real applications cases, as the concurrent leaks isolation in a pipeline and faults in a gas turbine, illustrate the advantages of the structural model to formulate proper diagnosis tasks.

Abstract: There are still wide gaps between theoretical approaches to capture, describe and manage business processes and accepted practical applications. The problem cannot be solved by consultants alone but must be internalized by the enterprise users in order to competently establish and maintain process automation. Originally being developed for IT-systems and production process automation, business process architecture and business process modelling has increasingly become an issue for the provision of services, a protagonist field being supply chain management. Seaports are important nodes in international supply chains and extremely heterogeneous, hosting enterprises of all sizes and a wide variety of administrations. To establish an architecture allowing for distinct views and to capture relevant processes is not only required to initiate automation, it is essential to allow the involved parties to understand each other and to identify common objectives. Within the research project "Effective Operations in Ports" (EFFORTS), co-funded by the European Commission, actors from specific ports all over Europe need to establish a common process platform. The CIMOSA concept was chosen to develop such a platform.

Abstract: Designing and consequent assembly of a new vehicle is a complex process as it requires close coordination and inputs from a number of disciplines in developing a number of systems and sub-systems in the vehicle that should fit within the confined vehicle space, function and provide the customers an acceptable combination of all relevant vehicle attributes. Understanding how these processes interact and how they are aligned with other while they should support the tasks involved in the conception of a new vehicle at a minimum time and cost. The first step to achieve this goal is the Modeling Business Process using UML (industry standard language).

Abstract: Integration technologies applied to product development is an important issue at Product Lifecycle Management (PLM) research area. There is a need to explore new approaches to improve product development in a collaborative and globally manner. This paper presents a PLM approach to evaluate and analize collaboration methods applying reverse engineering process. The research work uses a lathe case study developed by EAFIT University in Medellín, Colombia and supported by PLM laboratory infrastructure from Tecnologico de Monterrey, México. This paper argues that new integration technologies using PLM tools and reverse engineering improve the product development process. The first two stages of a case study are presented and the further research is to fully automate the manufacturing process of a lathe through reverse engineering.

Abstract: A monitoring system for the cutting tool condition for an industrial machining center is proposed. Four matching patterns and stochastic modelling approaches (Artificial Neural Network, Learning Vector Quantization, Support Vector Machine, and Hidden Markov Model) are compared for the diagnosis step. Integration of several sensor signals into a single fused estimation is considered. Several performance indexes such as binary and multiple classification, false alarm and false fault rate, and operating costs are considered for the comparison. Early results show that Hidden Markov Model-based approach fusing three sensors outperforms other techniques and exhibits 98% efficiency.

Abstract: High speed machining implies both high production and product quality, where surface roughness is an important performance index. A proposal for a supervisory control system is presented that predict the cutting parameters in peripheral milling process based on monitoring the surface roughness and the cutting tool condition. The novel framework consists of four modules: data acquisition system, cutting tool monitoring, surface roughness prediction and intelligent planning. Given its relevance, the surface roughness prediction module is presented in detail. A general model is introduced that considers several aluminum alloys, cutting parameters, geometries, and cutting tools. Early results validate the potential benefits of the cost-effective supervisory control system.
