Adaptability

In order to put virtual supply chains into practice a suitable option for coordination is necessary. This contribution presents which actors and which processes are required, if the problem will be solved by electronic marketplaces. Finally it will be shown which chances and opportunities are associated with the suggested approach.

The demands on production companies increasingly vary due to unpre-dictable changes. This results in batch production of varying products and shorter life cycles of products and leads to difficulties in controlling the production sequences. In order to maintain optimal production processes the machining systems, including the controllers, must be adapted, when changes get too drastic. Thus autarkic modules with standardised interfaces for mechanical connection, energy, and information are required. As the adaptation process must be manageable und executable in a short time, self-adapting control systems, which adapt themselves depending on the changed machine structure, are needed.

Changeable enterprises are sustainably focussing market and technology changes ranging from a short term up to long term view to maintain market success under changing market and environment conditions. The specific addressing of competence development can provide a significant contribution to changeable conditions. For these both, adaptive reactions to present changes as well as preventative planning addressing future changes are needed. To support the changeability of an enterprise holistic competence management approaches can be used. They allow to match supply and demand of competence and to design corresponding concepts for competence development.

Due to the dynamic production environment with its multiple fast changing influences, planning and reconfiguration cycles in production have become shorter. In this context, changeability and flexibility of production systems are major factors for success. The paper defines changeability and describes flexibility as major base for changeability. With the concept of Production Projects an innovative and promising concept is introduced that supports the systematic optimization of flexibility and that links the lifecycles of products and production. Furthermore, the Flexibility Mode and Effect Analysis (FlexMEA), on which the systematic analysis and optimisation of flexibility is based, is presented.

New technologies are often drivers of structural change, which in many cases leads to profound organizational and infrastructural changes in industry and within the enterprises. The aim of business action is to be versatile. That means that enterprises should play the role of the main actor of change instead of reacting only. The technology calendar described in this article is a strategic planning instrument. With this instrument it is possible to gain an overview about technologies available now and in future. From the confrontation of the product spectrum that can be manufactured in future and the technologies available in future, the necessary organizational and infrastructural measures, which result as consequence from the technological change, can be initiated. This way the planning of business change becomes possible.

In today’s changing market forecasts have become much less certain, thus seriously affecting in-house planning. The need to be able to adapt, on the other hand, is increasing. Transformability has therefore become a decisive key factor in the competitiveness of manufacturing companies in addition to the classical target factors of costs, time and quality. Nevertheless, transformability is seldom taken into sufficient consideration or implemented in practice, for it requires additional investments and the returns are not always clear. This paper describes a method that makes it possible for companies to calculate the relevant costs of changeability using the technique of scenario planning.

The new Collaborative Research Centre “Autonomous Cooperating Logistic Processes: A Paradigm Shift and its Limitations”, funded by the German Research Foundation, started on January 1st, 2004 at the University of Bremen. The objective of the new Collaborative Research Centre is systematic and broad investigation and application of “autonomy” as a new paradigm for logistic processes. For this, appropriate concepts and models as well as methods and tools are being researched and developed in twelve scientific sub-projects. In a later phase of the Collaborative Research Centre, the results of this research will be transferred into real logistic applications.
