An Analysis of the Proactive Approach as a Potential Tool for Adaptability in Production Systems
KTH, School of Industrial Engineering and Management (ITM), Production Engineering.
2011 (English)Licentiate thesis, comprehensive summary (Other academic)
Abstract [en]

Competitive systems for manufacturing, especially assembly systems, have to cope with frequent changes of external as well as internal demands. A proactive behaviour in an assembly system should make it capable of rapid changes and have an ability to handle frequent changes and disturbances.

During recent decades several different system theories have occurred of which the majority remained theories never taken to actual production solutions.

The thesis presents results from four case studies.

 

It is suggested, that the proactivity of an assembly system is strongly influenced by the system’s ability to change the three parameters:

1) level of automation,

2) level of information,

3) level of competence[l3]  (among the operators in a defined work area).

 

Proactivity is not easy to describe. However, this[l4]  thesis has taken a step in that direction. A general definition of proactivity is “taking action by causing change towards a state and not only reacting to change when it happens”. Another way to phrase this is "to be anticipatory and taking charge of situations”.

Proactivity can be described as the ability of preparation for:

- Changes and disturbance during operation;

- Planned long-term evolution for a sustainable and perfect production system.

 

Such a system consists of technical components efficiently integrated with human operators and has the ability to handle frequent changes. Proactivity in an assembly system is dependent on the following factors:

-         Continuous changes;

-         Mandate to allocate resources;

-         Mandate to do short term planning.

The thesis presents a first model for evaluation of different technical resources that contributes to an overall proactive system behaviour. The model has been published but not yet tested.

Abstract [en]

Manufacturing competitiveness is highly dependant on companies' ability to rapidly reconfigure their manufacturing and assembly systems. Efforts to approach emerging and self-reconfigurable systems could be successfully complemented by efficient integration of highly flexible human operators into the system. The concept of system proactivity is introduced which is based on the interrelated levels of automation, information, and competence in the assembly system. An ongoing project to develop proactive assembly systems, ProAct, is described.

Abstract [en]

Competitive assembly systems must cope with frequent demand changes, requiring drastically shortened resetting and ramp-up times. Characteristics of assembly systems capable of rapid change are e.g. Flexibility; Robustness, Agility, and ability to handle frequent changes and disturbances. This paper proposes proactivity as a vital factor of semi-automated assembly systems to increase speed of change. Proactive systems utilize the full potential of human operators and technical systems. Such systems have ability to dynamically change system automation levels, resulting in decrease of time consumed for assembly tasks. Proactivity criteria for assembly systems are reviewed based on theory and industrial case studies

Abstract [en]

Increasing customisation of products results in decreasing production batch sizes, especially in the final assembly. Industry must therefore increase their capability to handle smaller batches as well as radically decrease set up time between different product groups and new products. This paper suggests the need for further development, primarily addressing time parameters in dynamically changing assembly systems. We propose proactivity as a vital characteristic of semi-automated assembly systems, to increase fulfilment of customer demands and decrease non value-adding tasks. In proactive assembly systems, the full and complementary potential of human operators and technical systems is utilised. Criteria for proactivity in assembly systems are reviewed from automation, information, and competence perspectives.
