Process Planning by Integrated Design and Evaluation of Technology Chains Using a Standard ERP-System
The configuration, evaluation and selection of technology chains are some of the most critical tasks, regarding the determination of optimal product and production costs. Nonetheless, these process planning tasks are often still performed in a sequential way and are only unsatisfactorily considered within the process of product development. This paper presents a methodology to overcome these shortcomings, using an integrated configuration and evaluation of technology chains. Its implementation with a standard ERP (Enterprise Resource Planning) System is shown. Basically, the proposed methodology consists of three components. The first one is a product-technology-matrix that specifies the correlations between a company’s products and its available or projected technologies. The second component is a modular generic technology chain model that enables a classification of technologies. A combined quantitative and qualitative evaluation model to calculate and compare different technology chains completes the proposed methodology. These three elements facilitate an appropriate knowledge management concerning products, technologies and their relations. Additionally, a fast configuration of alternative technology chains and a selection of the most adequate ones for newly designed products are addressed, reducing the time of planning processes by almost one quarter. The implementation of the methodology using a standard ERP system is illustrated by two representative use cases.
