“…Special attention should be reserved to the choice between physical and virtual prototypes. In fact, this is acknowledged to be an important and not self-evident decision (Tahera et al , 2012), impacting the product design and development outcomes. Someone believes that the role of virtual prototype is that of substituting physical ones (Wang, 2002), maybe considering a different design-build-test cycle, as shown by Ullman (2010), where a higher number of fruitful iterations between “designing” and “testing” (virtually) should be possible.…”

“…Still another point of view is that of Elverum and Welo (2015), who observe that within the context of new product development of automotive parts, physical prototypes provide larger potential for exploration that digital (or virtual) ones. More generally, some pros and cons related to the two different prototyping types have been highlighted in literature (Broek et al , 2000; Camburn et al , 2015; Jensen et al , 2016; Tahera et al , 2012) and some preferred application for virtual ones have been inferred (Chun et al , 2012; Dunlap et al , 2014; Tiainen et al , 2014). It has also been observed that an integrated use of the two mentioned approaches, if correctly used, can certainly bring to non-negligible benefits (Tahera et al , 2010, 2014).…”

Purpose This paper aims to argue about the involvement of additive technologies (ATs) in the prototyping issues of designing. More precisely, it reviews the literature contributions focused on the different perspectives of prototyping activities for design purposes, searching for both available knowledge and research needs concerning the correct exploitation of ATs. Design/methodology/approach A two-step literature review has been performed. In the first step, general information has been retrieved about prototyping issues related to design. In the second step, the literature searches were focused on retrieving more detailed information about ATs, concerning each of the main issues identified in the previous step. Extracted information has been analyzed and discussed for understanding the actual coverage of the arguments and for identifying possible research needs. Findings Four generally valid prototyping issues have been identified in the first step of the literature review. For each of them, available information and current lacks have been identified and discussed about the involvement of AT, allowing to extract six different research hints for future works. Originality/value This is the first literature review concerning AT-focused contributions that cover the complex and inter-disciplinary issues characterizing prototyping activities in design contexts.

“…Physical prototypes are being pushed back for these cost reasons. (Tahera, 2014) These advantages of common CAT support the assumption of investigating novel processes for their suitability. Virtual Reality (VR) technology can represent a new possibility in this context.…”

Product development is time-consuming and cost-intensive. Part of the costs can be attributed to physical tests. Therefore, new methods are being researched to save resources. One upcoming area that becomes important for the industry is Virtual Reality (VR) technology.In the state of research studies have already compared VR with methods such as CAD visualizations. However, there is a need for research regarding the comparison to physical models.Therefore, a comparative study between a physical system and a VR system is evaluated in terms of functional analysis. The study task was to analyze the mechanism of a lawn sprinkler. For evaluation, a function explanation in a final interview was used.Although more different representations were possible with VR, there was no general improvement. This could be because movements were more difficult to visualize and recognize. The VR application is very suitable if you mainly have to look at systems that are difficult to view in reality. For example, some physical systems may be challenging to see in operation or may not allow a physical cut, so VR can be a solution. The advantages of physical systems can be in using other impressions, such as a feeling of certain forces.

“…Indeed, multiple works [15][16][17] have identified that designers maintain subjective beliefs about the true state of the system design during the design process. In this regard, verification activities mitigate the epistemic uncertainty on a system design by revealing more information about the true current state of the system design 18 Yet, a majority of the literature on verification activities adopts the aleatory uncertainty approach 2,3,5, [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] The reader is referred to 13,35 for a discussion on these works and the drawbacks of adopting the aleatory uncertainty approach to model systems engineering projects.…”

Optimal verification strategy for general development plans using a belief‐based approach

Verification activities are intended to reduce the costs of system development by identifying design errors before deploying the system. However, subcontractors in multi‐firm projects are motivated to implement locally cost‐effective verification strategies over verification strategies that benefit the main contractor. Incentivizing verification activities is one mechanism by which the contractor can motivate subcontractors to implement verification strategies desirable to the contractor. In this paper, we present a belief‐based modeling concept for determining optimal verification strategies for general development plans. The results show that the optimal incentives are a function of the subordinate firm's beliefs and the influence exerted by the subordinate firm on the supervising firm with respect to verification activities.
