Abstract [en]

In today’s turbulent environment, manufacturing companies are forced to efficiently change or develop production systems that are robust and dynamic enough to handle changing production situations during its entire life-cycle. To achieve such a production system requires a structured development process that should be carried out simultaneously to the product development process and considers the company’s product portfolio. Within a structured development process, the requirements specification of the proposed system is vital since it will guide the design process and the evaluation of the system on a conceptual as well as a detailed level.  The aim of this paper is to address the requirement specification process that covers all aspects of the production system to be designed. This paper argues for the need of a holistic view in the requirement specification process of production systems. A holistic view of the overall process will facilitate to manage the various demands and categories important to deal with in the specification of requirements. Based on the holistic view it will be possible to identify the gates and stakeholders of the process itself, but also the substantial content of this process map.

Abstract [en]

This paper presents empirical findings on manufacturing characteristics at subcontractor small and medium sized manufacturing enterprises (SMME). The SMME:s play a significant role in today’s economy, but they do not act to the same extent on the global market as the international larger companies. To remain competitive on the global market SMME:s should improve manufacturing.

The study has been accomplished in different industries and different sizes to identify their characteristics. The results indicate that SMME:s are focused on process technologies and not on the entire manufacturing system. The companies also have difficulties in locating and hiring skilled people.

Abstract [en]

Assembly work settings enabling proactive behaviour of the assembly operators are considered to be an important factor enabling customization of assembly work. As a consequence, access to necessary and essential information is a critical means to support proactive behaviour of assembly operators. In this paper we propose a methodology for assessing information requirements supporting operators’ proactive activities and decisions. The methodology is based on work domain analysis and it was used for assessing the information flow in a real assembly setting. By analysing the structure of information exchange and the hierarchical means-ends relationships a number of conclusions could be drawn. The first is that in order to consider information needed for all possible work activities, work domain analysis is a suitable approach. Additionally, proactive behaviour is related to the access to information answering why and what-questions. Furthermore, development towards more proactivity among assembly operators may necessitate decentralised decision-making. It is also concluded that in order to identify intentional constraints of an assembly system with increased proactivity, it is necessary to examine the levels of automation. Furthermore, to reach productivity gains the levels of competence must be developed so that most proactive decisions will remain on the skill- or rule-based levels.

Abstract [en]

The paper reviews the idea of proactivity in an assembly system with respect to information and decision making. It begins with an explanation about the term proactivity and moves on to a discussion of necessary changes of the assembly system to become proactive. Further, this paper will consider the role of information in a proactive assembly system and its impact on the proactive behavior of an operator. The method applied in this paper is a literature study.

Abstract [en]

Creating a requirement specification for modify a production system design is difficult. When modifying a production system the methodologies utilized span from full methodical and rational way to a trial and error approach. Often when modifying a production system there is more or less no requirement specification done in advance at all. This is due to a number of causes e.g. time pressure and lack of knowledge in the specific area and strong focus on a quick solution. Low understanding of the effects of an absent requirement specification and unclear relations to how the outcome of the production system modification will be affected by the identified requirements is often why the requirement specification is neglected. To visualize the need and impact of the requirements specification on the final system it would be beneficial to simulate the requirement specification. A suggested technique is to create a model where verification of the requirement specification could be done. This paper demonstrates the requirement complexity from a SME perspective when implementing a new robot module in a production system at Componenta Främmestad, Sweden. The paper also elaborates and discusses a possible approach for deciding requirements for a production system design verification model.

Abstract [en]

Manufacturing competitiveness highly depends on companies' ability to rapidly reconfigure their assembly systems. This paper introduces the concept of assembly system proactivity based on interrelated levels of human involvement in a planed way will contribute to increased system ability to proactively address predicted and unpredicted events. Correct involvement of human operators will utilize the full combined potential of human and technical capabilities, also providing cost-efficient assembly system solutions. The ProAct (project presented) will develop proactive assembly system models, evaluating proactive, feature-based solutions. Focus is on realizing the potential of semi-automated system with relevant human involvement, i.e. operators with high skills adding e.g. flexible capability and functionality.
