Evolvable production systems

Abstract: Sustainability, given as a goal for future industry, is not only an issue for Production Engineering. Economy and Ecology are an actual concern of governments and individuals worldwide. An effort must be carried on in order to reduce energy and resource consumption, deal with the possibility of climate changes and, at the same time, keep competitive in a world ruled by economic demands. In accordance with these demands, the Evolvable Production Systems (EPS) has aimed at developing such technological solutions and support mechanisms. The essence of Evolvable Production Systems resides in building a system with several independent process-oriented modules that possess the ability to dynamically adapt to the changing conditions of operation. Evolvability aims to attain highly adaptable control and mechanical systems enhancing re-usability and interoperability of modules, extending their life cycle and enabling short deployment times at shop floor level. Customisation and the shorter life time of products demand a continuous adaptation of the manufacturing systems and consequently enterprises must change systems development from reaction to short-term events to long term strategic development [12]. Enterprises can follow this strategy by re-thinking their organisational levels and structure, aligning systems development re-engineering process (adopting EPS approach) with Business Process Re-engineering (BPR) in order to enhance manufacturing agility from management to shop floor level. This paper will present Evolvable Production Systems advantages in order to achieve such results towards more ecological and economically suitable production systems.

Capturing the life cycle environmental performance of a company’s manufacturing system

Abstract: This research has developed methods for manufacturing decision makers to measure manufacturing environmental performance and to predict the environmental consequences of alternative manufacturing system configurations. The ideas behind the methods are based on life-cycle thinking from the perspective of an industrial actor, and its decision makers, in the value chain of a product. The ideas are to (1) focus on the parts of the product life cycle that manufacturing decision makers can influence, (2) relate environmental consequences to changes in a manufacturing system, and (3) use a model in which discrete-event simulation (DES) is used to capture the dynamic features of a manufacturing system and life-cycle assessment (LCA) is used to quantify the life cycle environmental consequences. The aim has been to enable manufacturing decision makers to understand the environmental consequences of their actions. To do this, the ideas were further developed using a case study of a bearing unit production line. From the experience gained in that case study and from the knowledge foundation in previous published work we have developed three main methods. The first is a method to relate environmental consequences to a manufacturing actor when performing a life-cycle assessment (LCA), this to increase the relevance of results and the probability to find ways to improve the system. The second method suggests how system boundaries in an LCA can be drawn to specifically measure the environmental performance of an industrial actor’s manufacturing system. This is done by only considering this manufacturing system’s material losses and energy use when calculating its environmental impact. Finally, to capture the dynamic characteristics of a manufacturing system and enable what-if scenarios for changed production configuration, four methodological sub-proposals are suggested to create a DES-LCA model.

A comparison of the roles and responsibilities of manufacturing engineers in Japan and the United States

Abstract: The manufacturing engineering work in nine Japanese firms is structured by a horizontal division of labor between manufacturing design engineers and production process engineers, in contrast to a vertical division of labor between manufacturing engineers and technicians in three American firms. The production process engineers in the Japanese firms link manufacturing engineering processes closely with production processes, whereas less coordination between the two processes occurs in the American firms. Regarding product design, manufacturing engineering, and production processes in the Japanese firms, employees engaged in downstream processes are more heavily involved with work concerned with upstream processes than in the American firms.

On the use of problem-specific candidate generators for the hybrid optimization of multi-objective production engineering problems

Abstract: In the field of production engineering, various complex multi-objective problems are known. In this paper we focus on the design of mold temperature control systems, the reconstruction of digitized surfaces, and the optimization of NC paths for the five-axis milling process. For all these applications, efficient problem-specific algorithms exist that only consider a subset of the desirable objectives. In contrast, modern multi-objective evolutionary algorithms are able to cope with many conflicting objectives, but they require a long runtime due to their general applicability. Therefore, we propose hybrid algorithms for the three applications mentioned. In each case, the problem-specific algorithms are used to determine promising initial solutions for the multi-objective evolutionary approach, whose variation concepts are used to generate diversity in the objective space. We show that the combination of these techniques provides great benefits. Since the final solution is chosen by a decision maker based on this Pareto front approximation, appropriate visualizations of the high-dimensional solutions are presented.

Systems Informatics for Biomass Feedstock Production Engineering

Abstract: Biomass feedstock production is a significant part of the supply chain of bioenergy. It consists of an integrative framework of chemical and biological processes as well as technical operations. The introduction of systems informatics facilitates the flow of information between these processes and operations through the use of specific techniques such as knowledge management, concurrent science and engineering, software engineering, and decision support. These techniques are integrated in the production of biomass feedstock through an information system. The core element of this information system is a database system. The handling of the data of the database system occurs through a number of graphical user interfaces. The design of these graphical user interfaces is based on the use of metadata which correspond to the attributes of the tasks, subtasks, and technological equipments of the respective stages of the biomass feedstock production. Furthermore, these interfaces allow the initiation of a number of operations, such as optimization, simulation, analysis of experimental data, and collection of information in real time, with parallel use of a number of software packages specialized for each stage of the biomass feedstock production. This paper describes the development of the framework for this information system for biomass feedstock production.
