摘要： In parallel with the increase of the importance of life cycle management aspects the appropriate supply of information according to specific requirements within all life cycle phases becomes more important. By this, an information management system is needed which has to be based on an appropriate information technological infrastructure to secure the information flows between life cycle phases distributed in place and time. Within this contribution a reference model of such information technological infrastructures will be presented, which contains the most important elements to fulfil the complex tasks and can be used to derive specific infrastructures. Based on this reference model a simulation system is described which has the task to model and optimize information technological infrastructures.

摘要： This paper presents a design method dedicated to manufacturing firms' information and decision systems (IDS). It has been developed to help small and medium sized enterprises to follow a CIM (computer integrated manufacturing) approach. So our work is a contribution to the IDS modelling in the very particular field of manufacturing firms' IDS. However, the formal description techniques used in OLYMPIOS can be extended to other applications. But, in fact, what is really important, and what we want to focus on, is the philosophy of our works, in two words: coherence and continuity. The coherence of a model, which is the main factor of quality, can be obtained by the means of mathematical specifications (logic or algebra). But to match the specification to reality, and to preserve coherence until realisation and maintenance, one must manage the system life cycle in homogeneous and continuous approach. For example, OLYMPIOS uses object-oriented design techniques to cope with the complexity of industrial information. Then we have tried to take the object concept into account, as early as possible in the life cycle. We also had to cope with time (the ''dynamic'' side) so that we propose to introduce temporal features in objects. We propose a continuous life cycle, with partly automatic translations from analysis to design. (C) 1997 John Wiley & Sons, Inc.

摘要： Today's development of technical products that are fit for the market is characterized by the necessity to take the complete life cycle of a product into consideration at an early stage in decision-making processes. This information on the product life cycle and corresponding support mechanisms must be supplied accompanying the developmental stage but also for planning disassembly/recycle processes. This contribution presents a computer-aided tool for product development with disassembly and recycle adequacy, with an emphasis on the life cycle oriented assessment of product alternatives. Based on a joint database and integrating current marginal conditions, an approach for determining the economically optimized disassembly extent is subsequently described as basis for future-oriented recycle processes. The described software tools will support the recycling-oriented information management from product development tip to disposal of technical products.

摘要： This paper presents an overview of the problems and possible solutions for automation information management and utilization in the process industries. The process plant life-cycle model is introduced and the cost structure of process automation investments is reviewed in this context. The general trends in process industry and developments in automation technologies are described and their effects are discussed. The advances in engineering CAD systems and their usability in solving the information management needs over the lifetime of process plants is assessed. This paper also presents;one application of advanced engineering CAD system for automation information management in an oil refinery. (C) 1997 Elsevier Science Ltd.
