  • Quantifying Levels of Automation - to enable competitive assembly systems
  • 2012
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Production companies frequently have to meet demands and requirements, both internal and external, which trigger a plan for change in different production areas. Assembly systems of today are heading towards more customised production, i.e. smaller batches, shorter cycle times and increased number of variants. As a result, companies have to find more flexible methods for assembling their products and become more proactive in the assembly system itself. Identifying new strategies becomes vital and can be achieved by designing the assembly system in a structured way with the most advantageous cognitive and mechanical Level of Automation.The aim of this thesis is to show that by quantifying, measuring and analysing physical and cognitive Levels of Automation it is possible to enable competitive assembly systems. ‘If it is not Quantifiable it is not true’ – this is a common statement among engineers who rather use numbers than words when describing a phenomenon. This thesis will discuss the phenomenon of Levels of Automation from both a quantitative and qualitative point of view. Furthermore it will discuss whether it is necessary to have more than one level or dimension of automation and if so, what benefits this creates for industry when measuring and analysing Levels of Automation in their assembly systems.‘The future assembly systems will consist of highly skilled operators...’ In order to choose and use the right level of automation, the choice itself has to be structured and well based. This thesis will discuss the importance of a structured method and an easy-to-use tool to visualise and quantify the levels of automation in the current state of a system. Furthermore, it will show how this could be used in a future analysis.Lastly, this thesis will discuss the effects of changing mind-set from primary look at cost and productivity to also consider other parameters that could influence the system in order to be competitive.

  • Interaction between Complexity, Quality and Cognitive Automation
  • 2012
  • Ingår i: Proc. 4th CIRP Conference on Assembly Technologies and Systems (CATS 2012), Ann Arbor, 21-22 May 2012.
  • Konferensbidrag (refereegranskat)abstract
    • Today’s assembly systems are adapting to the increased mass customisation. This means shorter cycle times, more variants and a more complex environment for the operators. An industrial case study has been performed in order to describe relations between complexity, quality and cognitive automation. This article use quantitative methods to describe the complex environment. This is done in order to create a better understanding for the importance of using cognitive automation as an enabler in order to create a more competitive assembly system for the future.

  • Enabling Flexible Manufacturing Systems by Using Level of Automation as Design Parameter
  • 2009
  • Ingår i: Proceedings - Winter Simulation Conference. - 0891-7736. - 9781424457700 ; , s. 2176-2184
  • Konferensbidrag (refereegranskat)abstract
    • Handling flexibility in an ever changing manufacturing environment is one of the key challenges for a successful industry. By using tools for virtual manufacturing, industries can analyze and predict outcomes of changes before taking action to change the real manufacturing systems. This paper describes a simulation tool that can be used to study the effect of level of automation issues on the design of manufacturing systems, including their effect on the overall system performance, ergonomics, environment, and economic measures. Determining a suitable level of automation can provide a manufacturing system with the flexibility needed to respond to the unpredictable events that occur in factory systems such as machine failures, lack of quality, lack of materials, lack of resources, etc. In addition, this tool is designed to use emerging simulation standards, allowing it to provide a neutral interface for both upstream and downstream data sources.
