Automation decisions in flow-line assembly systems based on a cost-benefit analysis

摘要

Today, dynamic changes in market requirements call for high adaptability of the level of automation (LoA) in assembly systems. Traditionally, the viable LoA of flow-line assembly systems is calculated as a function of output and monetary costs thus neglecting the true problem complexity. This paper presents an approach for the support of automation decisions, using a range of non-monetary multivariable criteria, which were determined by means of a survey and expert interviews. With three partial models to a) describe assembly systems, b) estimate cost and benefits of proposed equipment scenarios and c) select automation configurations, this approach improves decision quality.
