abstract = {For years, manufacturing companies have faced an increasingly complex and rapidly changing market environment which is the result of, if nothing else, higher customer individualization. This particularly concerns SME's, whose competitiveness is increasingly dependent on the early identification of new customer and market requirements and their ability to dynamically respond to these in an adequate fashion. In order to meet the high standards demanded of the planning quality and planning safety with ever increasing complexity and the continuous reduction of the planning time available, SME-compatible IT technologies are needed for the simulation of complex manufacturing relations. The following article addresses this problem and in-troduces the method set ecoFLEX, which enables the simulation of targeted and dynamic alignment of existing plant structures, resources and value-added processes with new production requirements. Unlike digital factory planning tools, a complete picture of the specific plant situation is not required, as will be illustrated by selected case studies from the medium sized production sector.},

abstract = {Production companies operate in increasingly turbulent and discontinuous environments. The rapid speed of change, coupled with a high complexity of cause-effect relationships of industries, globally-dispersed markets, technologies and economic areas create great challenges to the manufacturing systems. Therefore, a more holistic view of technical and organizational freedom is needed in production to support sustainable planning, control and modification of manufacturing systems, which incorporate system and life cycle aspects to the goal of profitability. Hence, reliable statements about flexibility on different organisational levels in a manufacturing system have a considerable role to ensure resource efficiency.
The following paper details the concept for calculating the production flexibility and the application experience in industrial production from the flexibility assessment toolbox ecoFLEX. It enables the simulation of targeted and dynamic alignment of existing plant structures and value-added processes with external environmental and internal changes. Unlike digital factory planning tools, a complete picture of the specific plant situation is not required, as will be illustrated by selected case studies from the medium sized assembling and stamping production enterprises.

abstract = {For years, production companies have faced an increasingly complex and rapidly changing market, which results in higher client customization. These coupled with a high complexity of cause-effect relationships of industries, globally-dispersed markets, technologies and economic areas create great challenges to the manufacturing systems. Uncertain projections about future sales, fluctuations in quantities, new manufacturing technologies and shorter product life cycles with changing product requirements, at the same time with an increasing range of variants requires a continuous transformation of production structures to the current requirements on the market. As a consequence, methods for evaluating a company's production flexibility are of great significance. The following article discusses the experience gained in research results in medium-sized production. The use of the IT-framework “WertProNET” that emerged from these results shows the impact that production changes have on economical plant operation, and how unnecessary additional costs from the inefficient use of resources can be avoided.},

abstract = {Demands on production systems are changing constantly as a result of changing competitive conditions and are also closely linked to the performance goals of time, quality, costs and innovation ability. This results in an ever increasing selection between various competitors, with the most important selection criteria being customer individualization, an increasingly shorter product life cycle and new technological innovations. This situation creates an existential need for production companies to manage to adapt over time to the changed surrounding conditions and plan their resources in a way that makes them suitable for cost-effective and market-oriented manufacturing. The following article presents the computerized methodology of an innovative evaluation technique called ecoFLEX which allows the measurement of a production system's flexibility. At first the paper details the general concept for estimating production flexibility and the approach to concretely calculating the flexibility on different production levels. Furthermore, it presents the practical experience gained in ecoFLEX during its application at a small and medium enterprise (SME) to evaluate the complex manufacturing coherencies from the perspective of their efficiency. Especially it will be shown how the usage of flexibility indices calculated by ecoFLEX helps to come to the right decision on the strategic and operational level in production systems.},
