Open System Architecture for CIM


Book Description

On Integration computer applications have by now entered almost all enterprises, but mostly in an uncoordinated way without long term integration plans or automation strategies. Departments introduced computing equipment and purchased or developed programs to support their department operations. This approach divided an enterprise into small and almost autonomous enterprises, each with the goal to deploy the computer to make their department and its associated activities work more efficiently. Thus many departments acquired computers, developed and installed automation systems and PCs and educated their staff, announcing this was done to make the work force aware of the large benefits that computers bring. In this fashion the most important functions in an enterprise were more or less computerized (accounting more, CAM and CAD less). In 1986 Europe, the level of computerization in descending order of significance was as follows: Accounting, Inventory Control, Order Entry, Production Planning & Control, Purchasing, Distribution, Sales Planning, Shop Floor Control, Process Control, Quality Control, Manufacturing Engineering (including CAM), and finally Design Engineering (with CAD) [1]. The net result (something that dawned upon us after decades) was that the enterprise consisted of many II islands of ll automation • Moreover, these islands could even be found within departments, where specific functions had been computerized without regard to the impact on the remainder. In the late seventies it became clear that smooth transfer of information between enterprise activities and even within departments was a burden, if at all possible.




CIMOSA: Open System Architecture for CIM


Book Description

Enterprise operation efficiency is seriously constrained by the inability to provide the right information, in the right place, at the right time. In spite of significant advances in technology it is still difficult to access information used or produced by different applications due to the hardware and software incompatibilities of manufacturing and information processing equipment. But it is this information and operational knowledge which makes up most of the business value of the enterprise and which enables it to compete in the marketplace. Therefore, sufficient and timely information access is a prerequisite for its efficient use in the operation of enterprises. It is the aim of the ESPRIT project AMICE to make this knowledge base available enterprise-wide. During several ESPRIT contracts the project has developed and validated CIMOSA: Open System Architecture for CIM. The CIMOSA concepts provide operation structuring based on cooperating processes. Enterprise operations are represented in terms of functionality and dynamic behaviour (control flow). Information needed and produced, as well as resources and organisational aspects relevant in the course of the operation are modelled in the process model. However, the different aspects may be viewed separately for additional structuring and detailing during the enterprise engineering process.

Computer-Assisted Management and Control of Manufacturing Systems


Book Description

Modem manufacturing systems involve many processes and operations that can be monitored and controlled at several levels of intelligence. At the highest level there is a computer that supervises the various manufacturing functions, whereas at the lowest level there are stand alone computer controlled systems of manufacturing processes and robotic cells. Until recenty computer-aided manufacturing systems constituted isolated "islands" of automation, each oriented to a particular application, but present day systems offer integrated approaches to manufacturing and enterprise operations. These modem systems, known as computer-integrated manufacturing (CIM) systems, can easily meet the current performance and manufacturing competitiveness requirements under strong environmental changes. CIM systems are much of a challenge, and imply a systemic approach to the design and operation of a manufacturing enterprise. Actualy, a CIM system must take into account in a unified way the following three views : the user view, the technology view, and the enterprise view. This means that CIM includes both the engineering and enterprise planning and control activities, as well as the information flow activities across all the stages of the system.




Balanced Automation Systems


Book Description

Towards Balanced Automation The concept. Manufacturing industries worldwide are facing tough challenges as a consequence of the globalization of economy and the openness of the markets. Progress of the economic blocks such as the European Union, NAFTA, and MERCOSUR, and the global agreements such as GATT, in addition to their obvious economic and social consequences, provoke strong paradigm shifts in the way that the manufacturing systems are conceived and operate. To increase profitability and reduce the manufacturing costs, there is a recent tendency towards establishing partnership links among the involved industries, usually between big industries and the networks of components' suppliers. To benefit from the advances in technology, similar agreements are being established between industries and universities and research institutes. Such an open tete-cooperation network may be identified as an extended enterprise or a virtual enterprise. In fact, the manufacturing process is no more carried out by a single enterprise, rather each enterprise is just a node that adds some value (a step in the manufacturing chain) to the cooperation network of enterprises. The new trends create new scenarios and technological challenges, especially to the Small and Medium size Enterprises (SMEs) that clearly comprise the overwhelming majority of manufacturing enterprises worldwide. Under the classical scenarios, these SMEs would have had big difficulties to access or benefit from the state of the art technology, due to their limited human, financial, and material resources.




Advances in Production Management Systems


Book Description

This book is divided into four sections: invited papers, principles, systems and techniques. The invited papers form an extensive overview of the state-of-the-art of production management. The themes range from the everlasting hunt for better productivity to the implications of CIM architectures (particularly CIM-OSA) for production management. The other three sections of the book look at the various problems affecting production management. One of the characteristics of modern production management is the need for better principles, systems and techniques for interorganizational production management. Another topic of crucial relevance is the necessity to master not only repetitive manufacturing but also one-of-a-kind product manufacturing. From the managerial point of view, the forecast-based make-to-stock principles have proven insufficient, with market forces demanding fast and reliable deliveries of customer-oriented products. The goals of production management have been re-evaluated as a result.

The key technologies which are being developed, and the results emerging from the collaborative projects, have contributed to the establishment of an integrative approach to manufacturing problems which embraces engineering, logistics, process automation, business functions, organizational and environmental concerns.




Viewpoint-based Flexible Information System Architectures


Book Description

Information system architecture (ISA) specification as a part of software engineering field has been an information systems research topic since the 60's of the 20th century. There have been manifold specification methodologies over the recent decades, developed newly or adapted in order to target the domains of software modelling, legacy systems, steel production, and automotive safety. Still, there exist considerable issues constituting the need for a flexible ISA development, e.g. incomplete methodology for requirements in model-driven architectures, lacking qualitative methods for thorough definition and usage of viewpoints. Currently existing methods for information system architecture specification usually de- vise the target architectures either addressing only a part of software life-cycles or neglect- ing less structured information. The method for flexible information system architectures (FISA) specification uses the viewpoint concept for mediating the domain expert and technical system levels. The FISA-method defines construction and application reference models based on the ANSI/IEEE Standard 1471-2000, viewpoints with model transfor- mations based on OMG-Standard Model-Driven Architecture (MDA), and four different approaches for ISA specification, thus providing for flexibility both in construction and refactoring procedures. The development of FISA-method has been based on a thorough analysis of the ISA specification method field and constructs a comprehensive procedure and reference engi- neering models for flexible ISA specification. The genericity of the conceived construction and application procedure models of FISA allows for its usage not only in research, but also in industry settings, as presented on illustrative scenarios in steel manufacturing and automotive safety.




Engineering Systems with Intelligence


Book Description

This book contains a selection of papers presented at the "European Robotics and Intelligent Systems Conference" (EURISCON '91) held in Corfu. Greece (June 23-28. 1991). It is devoted to the analysis. design and applications of technological systems with built-in intelligence achieved through appropriate blending of mathematical, symbolic. sensing. computer processing. and feedback control concepts. methods and software / hardware tools. System intelligence includes human-like capabilities such as learning. observation. perception. interpretation. reasoning. planning. decision making. and action. Integrated intelligent decision and control systems obey Saridis' prinCiple of Increasing Precision with Decreasing Intelligence (IPDI). and have a hierarchical structure with three basic levels. namely Organization. Coordination. and Execution Levels. As we proceed from the organization to the execution level. the precision about the jobs to be completed increases and accordingly the intelligence reqUired for these jobs decreases. As an example. it is mentioned here that in an intelligent robotic system the organization tasks can be realized using a neural net. the coordination tasks by a Petri net. and the execution tasks by local sensors and actuators. The field of intelligent systems is a new interdisciplinary field with continuously increasing interest and expansion. It is actually the outcome of the synergetic interaction and cooperation of classical fields such as system theory. control theory. artificial intelligence. operational research. information theory. electronics. communications. and others.
