INTO
Human and machine - Performance by human-oriented automation
Project Leader and Principal Investigator at Aalto University: Prof. Heikki Koivo
Principal Investigator at ASE: Prof. Hannu Koivisto
Duration of the project: 2009 – 2011
Project description:
The project concentrates on the systematic analysis and development of the human-process/machine-interaction. The aim is also the overall optimization of a work or process chain consisting of several individual machines or industrial processes. Generic theoretical background and practical tools for managing the human-machine combination will be developed in the project. This improves the service business of the participating equipment suppliers as well as the process effectiveness and product quality of the end user companies. More info in Finnish.
ASE developed methods for forest harvesting machines, rock crushers and nickel leaching processes. The method developed for the recognition of machine work tasks and work cycles is based on the combination of multivariate control signals generated by the operator. The recognition of work cycles and tasks is based on Hidden Markov Models (HMM). As the actions of the operator become recognizable, the operator’s effect to the overall performance of machine work does not need to be regarded as an unknown disturbance. The model of the crushing process is based on the well established theories of crushing and process experiments. The main goal is to present a dynamic process simulator suitable for later use in control system design and control strategy planning. For nickel leaching an operator decision support system was developed.
