- Functional Products (FP) and Product Service Systems (PSS) may be seen as integrated systems comprising hardware and support services. For such offerings, availability is key. Little research has been done on integrating Data Stream Management Systems (DSMS) for monitoring (parts of) a FP to improve system availability. This paper introduces an approach for how data stream mining may be applied to monitor hardware being part of a Functional Product. The result shows that DSMS have the potential to significantly support continuous availability awareness of industrial systems, especially important when the supplier is to supply a function with certain availability.

Konferensbidrag (refereegranskat)abstract
- In today’s industry, functional provision is becoming more and more important, necessitating increased simulation support. In this paper, the objective is to present a modeling and simulation approach for simulation-driven design (SDD) to support function development. The scope of this paper is simulation support for developing hardware equipment used in processing industry. The research is founded on industrial needs identified through two parallel interview-based studies in the Swedish process industry. Both companies explore doing business with functional products rather than hardware, in scenarios where the responsibility for and availability of the functions may remain with the service provider. One as-is and one future (to-be) scenario are presented. A decomposition of a general processing function (applicable to both companies) describes how the companies transfer machine input to output specifications. The decomposition includes customer and provider value and the paper demonstrates, as part of the results and based on the SDD approach, how that value may be increased through evaluation and prioritization. Additionally, the SDD approach shows that it is possible to identify a set of solutions which meet the specified requirements, supporting evaluation and prioritization of business offers and activities.

Tidskriftsartikel (refereegranskat)abstract
- During the last few decades, and in order to increase product development efficiency, simulations strategies have been developed to guide designers towards better solutions rather than to verify suggested and basically unevaluated solutions. Such approaches are often called Simulation Driven Design (SDD), which is of interest in this review. The objective of this paper is to show the research evolution of SDD and identify the state of the art in SDD methodology. The literature review comprises several hundred references, of which 79 are included in this paper. The results comprise the state of the art in simulation driven design including the history, various definitions, criteria and effects of using SDD approaches.

Mechanics of materials and structures: a simulation-driven design approach

- Engineering product development has developed considerably over the past decade. In order for industry to keep up with continuously changing requirements, it is necessary to develop new and innovative simulation methods. However, few tools and methods for simulation-driven design have been applied in industrial settings and proven to actually drive the development and selection of the ideal solution. Such tools, based on fundamental equations, are the focus of this paper. In this paper the work is based on two cases of mechanics of materials and structures: welding and rotor dynamical simulations. These two examples of simulation-driven design indicate that a larger design space can be explored and that more possible solutions can be evaluated. Therefore, the approach improves the probability of innovations and finding optimal solutions. A calibrated block dumping approach can be used to increase the efficiency of welding simulations when many simulations are required.

A development process for Functional Products : hardware, software, service support system and management of operation

Tidskriftsartikel (refereegranskat)abstract
- The development process for a Functional Product (FP) is complex and there is a need to coordinate, monitor, control and share information as well as to communicate properly among the parties involved in the process. This paper proposes a conceptual development process to manage the FP development, including development of hardware, software, service support system, and how to manage the operation of an FP. Further, challenges related to the integrated development of FPs are also discussed.

Functional product development : what information should be shared during the development process?

Tidskriftsartikel (refereegranskat)abstract
- The development process for a Functional Product (FP) is complex and there is a need to share information as well as to communicate it among the parties involved in the process. The paper concerns shared information that is of specific interest when developing FPs, in contrast to information that must be shared during a general product or service development process. The findings are compiled in a conceptual table comprising such specific information items pertaining to both the initial development as well as post development parts of an FPs lifecycle. This table can be used as an aid to any development process or method, as it points out information items that must necessarily be shared, but not how they to be shared.

A modelling and simulation approach for linking design activities to business decisions

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The business environment of the manufacturing industry is changing from a hardware-based product focus to a process and function focus. A current industrial interest is the development and sale of functions. This function could be realised as a product based on hardware, software and services, and may be sold as a function rather than as hardware. This function view is referred to as Functional Products (FP). The new focus for the customer is on value rather than hardware. This presents new challenges for how engineering hardware design may best be carried out. Sale of functional products requires a changed business model in which the price of the functional product is related to the functionality of the product itself; hence the name functional product. The supplier can in such a scenario no longer sell maintenance and spare parts. Instead, these activities become a cost, thus motivating the supplier to increase process efficiency, decrease internal production cost by using less energy per produced unit and increase knowledge about use-cases. The researcher's challenge is how to create new knowledge regarding functional product development for academic as well as for industrial benefit. The research question was formulated as: How may methods or tools for design process modelling and simulation be developed to support functional product development? Four case studies were carried out in Swedish industry. Case study 1 was carried out in cooperation with Hägglunds Drives AB. Case study 2 was carried out in cooperation with companies Hägglunds Drives AB, Volvo Aero and Volvo Car Corporation. Case study 3 was carried out in cooperation Volvo Aero and Case study 4 was carried out in cooperation with nine industrial companies during the formation of the Faste Laboratory, Centre for Functional Product Innovation. Results include the need for integrating product development process and company strategy for functional product development and the identification of the need for new methods and tools to enable better understanding of technology and business processes. The research shows the possibility of evaluating cost and time of development before doing the actual product development work by modelling and simulating the design process. Thus, the knowledge that previously was implicit in the work process is made explicit and possible to manipulate for a desired outcome. Linking the future business cases to work processes by modelling and simulation enables knowledge re-use and work-process predictions concerning cost and time. Hence, modelling and simulation of work processes results in better knowledge of company development capacity earlier than before, thus allowing shorter reaction time to changes in the business domain.
