    Planning and multicriteria optimization of design processes
    ( 1996)
    Krause, F.-L.
    ;
    Golm, F.
    Proceeding from the assumption that in the future an intensified re-engineering of business processes in the area of product development will be necessary, the development of powerful tools in this area appropriate. An approach is presented providing the support for the restructuring and optimization of business processes surpassing the functional scope of commercially available tools. The approach sets the further goal of imploying the business models generated to perform a multi-criteria process optimization as well. This optimization is to be performed in an automated fashion under end-user control based on a process-related system of key-figures.

    Business process reengineering
    ( 1995)
    Neubauer, G.

    Krause, O.
    The concept of business Process Reengineering with its major characteristics is discussed. Features of processes critical to business sucess are highlighted. A survey among 600 US und EU firms showing how Reengineering affects the key performance indicators like customer satisfaction, quality, productivity, market share, turnover, cycle time und cost is evaluated. A structured approach supporting successful Reeengineering is introduced. Benefits of the IPK methodology of Integrated Enterprise Modelling (IEM) and the tool MOOGO are mentioned. Finally some key factors for sucessful change manangement highlighting the importance of a long-term strategy are given.

    Acceleration of value adding business processes. An example from German machine-too engineering. A basic requirement for production entrepreneurs is the new orientation of order handling along the chain of value adding to accelerate business processes. This article presents an example from German machine-tool engineering.

    When approaching targets like strenghtening productivity of the company by improving product quality, reducing lead time and optimizing market driven pricing. companies start to concentrate on their main business processes, on gearing all functions and ressources to the process they are involved in and on improving communication by sharing information widely within the processes. In the following the approach of Integrated Enterprise Modelling IEM using Object-Oriented Modelling Technique to model and to clarify the interaction of enterprise components will be introduced. The method will be explained as planning tool by an example. The example describes the optimization of future CAD/CAM-applications as a communication instrument within the process to develop gears.

    To live a life beyond lean production European companies have to reorganize their structures using such strategic tools as value management, outsourcing and flexible manufacturing concerning their specific European characteristics. On one hand several methods have been worked out to support the make or buy decision process whether to keep services and the manufacturing of parts and subcomponents in-house or to buy them. Unfortunately cost oriented approaches like those based on transaction theory lack quantification of parameters because of traditional calculation- and controlling systems. Their practical use is yet limited. But during the last years it has become clear, that a proper use of make or buy concerning a corporations mix of strategies can strengthen its competitiveness. On the other hand various techniques help to structure the whole spectrum of parts into sets or part families to support the introduction of group technology or different forms of cellular manufacturing. Yet there still is a lack of methods that include both make or buy decisions derived from the company's stategy as well as the structuring of the production process based on the chosen core assemblies and components. The link between corporate and business strategies as described in the Swiss St. Galler management model (Gomez, 1993) and a set of criteria to identify a company's strategic 'make' components has been discussed in the previous paper. This article deals with a methodology to support the tasks on the modelling-/structuring level and the technological-/organizational level. The two mentioned papers describe a comprehensive approach to link the two issues of strategic make or buy and factory structuring and therefore support all tasks of comprehensive planning.

    Since product innovations are imitated immediately, competitive advantage of product innovations does not last very long whereas the process of gaining competence and experience in development and production requires great efforts for all competitors. International competition forces European production enterprises to decide about their future manufacturing strategy. This decision turns out to be of vital importance. The strategy for European manufacturers has to be putting focus on producing only a carefully selected spectrum of strategic products and components. The decision whether to keep a component or an assembly that has to be produced in-house is a strategic decision and cannot be dealt with as an operative question. The division Systems Planning at the Fraunhofer Institute for Production Systems and Design Technology (IPK), Berlin/FRG has developed a method for enterprises of production industry to maintain and even improve their market situation by selecting the company's cor e assemblies and core components.
