Abstract The paper proposes a modular functional modeling framework, which aims at integrating the different functional modeling perspectives, relevant to different disciplines. The results of two extensive literature studies on diverse functional modeling approaches proposed in a variety of disciplines are consolidated. These studies identified specific needs for an integrated functional modeling approach to support interdisciplinary conceptual design. The presented framework aims at fulfilling these needs. It consists of a variety of associated views, represented through different matrices. This matrix-based representation facilitates the analysis of different functional modeling perspectives and their interdependencies. Finally, the implications of the presented approach are discussed.

1 Introduction Functional modeling is proposed in systematic design approaches across disciplines. It is intended to support early concept development for a technical system, i.e. the transition from a design problem to an early solution concept. Functional modeling results in a first abstract representation of the technical system under development. The term ‘‘technical system’’ encompasses both technical products as well as product/service-systems (PSS) in this paper. Across and within different disciplines a large variety of function models is proposed and a common approach to functional modeling can hardly be found [1–4]. As a consequence, diverse ways of representing functions are competing when designers from different disciplines collaborate, potentially hindering the exchange expertise [1, 5]. Approaches to bridge the existing diversity, so far, have not been successful [2, 6]. This paper consolidates the results of two extensive literature studies on the diverse functional modeling approaches, proposed in a variety of disciplines [3, 4]. The considered studies identified specific needs for an integrated functional modeling approach linking the different functional modeling perspectives, which are prominently addressed in the proposed function models from different disciplines. This paper presents the concept of an integrated functional modeling approach, which aims at satisfying the identified needs.
