“…Each of these failure modes is individually assessed and allocated a risk priority number (RPN) as the product of an ordinally rated severity (S), probability (P) and likelihood of detection (D). A completed assessment provides insight into the function integrity (risk to function fulfilment) of a system thereby informing mitigation activities and design decision-making (Wichmann et al, 2020).…”

In seeking to retrofit decade old production systems, there is often the need to re-analyse many facets of the system as previous assessments and past assumptions must be validated or amended. The following paper presents the system modelling and analysis of an industrial cigarette filter maker. The matrix based Integrated Function Modelling (IFM) Framework was applied to model six design entities to create a comprehensive system understanding. The derived system model was subsequently analysed using the Function Integrity Diagnosis and Documentation (FIDD) method to identify risk to system function. Through the unique use-case discussed in this paper, new insights for improvement of the modelling approach and analysis method are identified. This paper concludes with actionable recommendations for improved application of the IFM Framework and FIDD method.

“…This paper investigates the possibility of using GBDLs for this endeavor. One major advantage of this integration is the opportunity of automated analyses in this domain, such as fault tree analyses (FTA-compare Riestenpatt gen. Richter and Rudolph [5]) and fault propagation path analyses, which could facilitate the estimation, planning and management of engineering change significantly [6].…”

The main focus of this paper is the integration of an integrated function modeling (IFM) framework in an engineering framework based on graph-based design languages (GBDLs). Over the last decade, GBDLs have received increasing attention as they offer a promising approach for addressing several important challenges in engineering, such as the frequent and time-consuming transfer of data between different computer aided engineering (CAE) tools. This absorbs significant amounts of manual labor in engineering design projects. GBDLs create digital system models at a meta level, encompassing all relevant information concerning a certain product design and feeding this into the relevant simulation tools needed for evaluating the impact of possible design variations on the performance of the resulting products/parts. It is possible to automate this process using digital compilers. Because of this, it is also possible to realize systematic design variations for a very large number of parameters and topological variants. Therefore, these kinds of graph-based languages are a powerful means for creating a large number of viable design alternatives and for permitting fast evaluation processes against the given specifications. While, thus far, such analyses tend to be based on a more or less fully defined system, this paper proposes an expansion of the applicability of GBDLs into the domain of product functions to cohesively link conceptual with embodiment design stages. This will also help with early systematic, automated generation and the validation of design alternatives through relevant simulation tools during embodiment design. Further, it will permit the automated exploration of function paths and enable extended analysis possibilities, such as the detection of functional bottlenecks, while enhancing the traceability of the design over the development process. For these extended analysis possibilities, a function analysis tool was developed that adopts core ideas of the failure mode and effects analysis (FMEA). In this, the functional distinction between function carriers and function-related processes allows the goal-directed assessment of component reliabilities and the detectability and importance of processes in a technical system. In the paper, the graph-based modeling of functions and the function analysis tools are demonstrated on the example of a multicopter.
