27. Efficiency assessment of Reconfigurable Manufacturing Systems

FIDETIA - University of Seville, Spain
Reconfigurable Manufacturing Systems (RMS) are advanced production systems designed for rapid change in its configuration, allowing it to adapt its production capacity and functionality to the dynamic changes of the demand of the part types. As with any other manufacturing system, the efficiency of RMS should also be assessed. In this paper, a novel Data Envelopment Analysis (DEA) approach is proposed to assess the technical efficiency of RMS by benchmarking the observed time allocation of the different system configurations and the inputs consumed and output produced in each of them. The inputs considered are the time usage of the different RMS modules, labour and energy consumed. The outputs are the number of units produced of each part type. The production possibility set is determined by previous observations, from which the best practices are identified. The proposed approach is illustrated on a simulated dataset.
91. Capability matchmaking procedure to support rapid configuration and re-configuration of production systems

Rapid responsiveness in terms of processing functions, production capacity and order dispatching is required from today’s production systems. This paper introduces a capability-based matchmaking procedure, which supports rapid configuration and re-configuration of production systems. The approach relies on formal OWL-based descriptions of both product requirements and resource capabilities. The base algorithm for the matchmaking is introduced together with the required rules for combined capability calculation and capability matchmaking. The presented approach supports the system designer and reconfiguration planner by automatically suggesting possible resource alternatives for certain product requirements.

Currently, there are many research about sustainable and eco-friendly manufacturing system. However, up to now, there are not many studies yet discussing about the integration between sustainability and self-reconfigurability. In this paper, the relationship between self-reconfigurability and sustainability is investigated, especially when a manufacturing system changes its process based on its new-determined goal. This paper also provides an experiment result by using simulation model consider a process reconfiguration and sustainability factors. Through existing research results, the literature is reviewed in order to obtain the relationship between self-reconfigurability and sustainability. The appropriate sustainability factors for self-reconfigurability such as energy efficiency, resource efficiency, and so on, has been checked and selected by using AHP(Analytic hierarchy process). Then, the simulation model will be developed by considering the selected sustainability factors. To check and analyze how sustainability factors affect manufacturing processes and how sustainability factors, also change when manufacturing process are changed. The result of this paper can be a basis for the future research to increase sustainability in a self-reconfigurable manufacturing system..
357. Towards practical guidelines for conversion from a fixed to a reconfigurable manufacturing automation system

It is generally considered to be a key requirement in the development of reconfigurable manufacturing systems, that economic feasibility is only attainable if the system is defined to be reconfigurable at the outset of its design. In this work we consider the potential exception to this requirement, in the context of a common industrial scenario where a specialized and expensive manufacturing machine or system will otherwise be rendered useless due to loss of business of the particular product being manufactured. Specific guidelines to convert from a fixed to a reconfigurable system are proposed, and evaluated through a case study.
