Condition-based Maintenance: Model vs. Statistics A Performance Comparison
(2016)Procedia CIRP ~ Factories of the Future in the digital environment - Proceedings of the 49th CIRP Conference on Manufacturing SystemsThe current development in industrial applications shows a variety of approaches to perform maintenance: With reactive maintenance, only parts which fail will be replaced. This causes high costs and high unexpected failure rates. Preventive maintenance uses a predefined service plan and also a wear part exchange schedule. The plan or schedule is often based on real-time or an operation time. This often results in fixed maintenance cycles ...Conference Paper -
Virtual reality based time and motion study with support for real walking
(2016)Procedia CIRP ~ Factories of the Future in the digital environment - Proceedings of the 49th CIRP Conference on Manufacturing SystemsManual operations in mass production are important cost drivers. Thus, tools like the MTM (Methods-time Measurement) – a time and motion study method – were introduced, which are nowadays established in industry for evaluation and improvement of production facilities. In this method, cardboard engineering is used to build simplified physical mock-ups of machines or production lines, in which the manual working process can be simulated. ...Conference Paper -
Real walking in virtual environments for factory planning and evaluation
(2016)Procedia CIRP ~ 6th CIRP Conference on Assembly Technologies and Systems (CATS)Nowadays, buildings or production facilities are designed using specialized design software and building information modeling tools help to evaluate the resulting virtual mock-up. However, with current, primarily desktop based tools it is hard to evaluate human factors of such a design, for instance spatial constraints for workforces. This paper presents a new tool for factory planning and evaluation based on virtual reality that allows ...Conference Paper
