One step of such management deals with prioritising those disturbances which should undergo root cause analysis. The focus of this work is on two areas. First, investigating current challenges faced by manufacturing companies when prioritising root cause analysis of production disturbances. Second, identifying the stakeholders and factors impacted by production disturbances. Understanding the current challenges and identifying impacted stakeholders and factors allows the development of more efficient prioritisation strategies and, thus, contributes to the reduction of frequency and impact of disturbances.Design/methodology/approachTo achieve the intended purpose of this research, a qualitative approach was chosen. A series of interviews was conducted with practitioners, to identify current challenges. A series of focus groups was also held, to identify the impacted stakeholders and factors by disturbances.Fin...

Flexibility can be interpreted at different time-scales. Object-oriented modeling supports long time-scale flexibility by simplifying the introduction of different equipment within the system without extensive reprogramming of the control system. Distributed product specification, where each (type of) product is specified independently of any other product that may be simultaneously produced, supports medium time-scale flexibility with feasible introduction of new products. Automatic synthesis of control laws, by use of the supervisory control theory, permits on-line recalculation of the control policies and thus supports short time-scale flexibility. We describe an integrated approach to increase flexibility of production-system control, where given a set of object-oriented resource models, and a set of distributed product specifications control-laws are automatically syn...

The complexity needs to be defined, and further operationalized to support management of production complexity. This paper's contribution is the empirical findings of perceived production complexity at three manufacturing companies, from the perspective of different functions/roles within the production systems; production engineers, operative personnel, internal logistics, and in ...

This paper presents research project aimed at developing a feasible definition of complexity, a method for measuring complexity, which supports line rebalancing, man-hour planning, and complexity management, competence, and information support. The project is done in collaboration between Swerea IVF, Chalmers, Volvo Cars, Electrolux, Stoneridge, Electronics, and AB Volvo. Industrial studies were ...
