A knowledge-based master model approach exemplified with jet engine structural design

2017

Successful product development requires the consideration of multiple engineering disciplines and the quantification of tradeoffs among conflicting objectives from the very early design phases. The single-largest challenge to do so is the lack of detailed design information. A possible remedy of this issue is knowledge-based engineering. This paper presents a knowledge-based master model approach that enables the management of concurrent design and analysis models within different engineering disciplines in relation to the same governing product definition. The approach is exemplified on an early phase structural design of a turbo-fan jet engine. The model allows geometric-, structural mech…

A methodology for the reduction of imprecision in the engineering process

1997

Abstract Engineering design is characterized by a high level of imprecision, vague parameters, and ill-defined relationships. In design, imprecision reduction must occur to arrive at a final product specification. Few design systems exist for adequately representing design imprecision, and formally reducing it to precise values. Fuzzy set theory has considerable potential for addressing the imprecision in design. However, it lacks a formal methodology for system development and operation. One repercussion of this is that imprecision reduction is, at present, implemented in a relatively ad-hoc manner. The main contribution of this paper is to introduce a methodology called precision converge…

Data and Information Quality Research in Engineering Construction Projects: A Review of Literature

2013

This article presents a review of the research on Data and Information Quality (DQ/IQ) assessment in engineering construction. Through a review of 445 articles on the topic, only nine were found in the context of engineering construction. The analysis of these nine articles revealed six challenges in performing DQ/IQ assessment in this context: the iterative nature of concurrent engineering, the uniqueness of engineering data, lack of integration between processes, lack of integration between systems, lack of timely information, and lack of relevant DQ/IQ assessment frameworks and tools. The specific contributions of this paper are the identification of DQ/IQ challenges in engineering const…

Platforms for Human-Human Interaction in Large Social Events

2012

In this paper we present the evolution of QRouteMe, an information system built to provide people with rich user experiences when attending museums or exhibits. QRouteMe is a platform for indirect, mediated, and facilitated interactions among humans during large social events, by means of a wide variety of concurrent technologies and devices. The system evolution is analyzed according to the new human-to-human interaction (HHI) research domain. In particular, we show how QRouteMe has been adapted for the different events in which it has been used. We analyze and describe social interaction aspects during the events and we discuss some data and results. Finally we outline some possible futur…

Shaping inter-firm collaboration in new product development in the automobile industry: A trade-off between a transaction and relational-based approa…

2008

Abstract Shaping collaboration in the new product development (NPD) has always been a very difficult task, especially in complex industries like the automobile one. This complexity is particularly true during the engineering phase of the NPD process, where different complex systems are to be designed in a collaborative way. Basically, two-kind of approaches have been observed in the literature and industry: one is more related to market transactions, specifically the west car-company style, the other is more relational based, as in the Japanese car-company style. Now, the increasing globalisation of the industry asks for a merge of the two approaches; indeed, the increasing use of standard …

Great expectations: Learning the boundaries of design rights

2019

We present a case study of an increase in design right filings and concurrent design right litigations in an industry that previously had little experience of design right protection. The motives for and outcomes of filing, and how these changed over time are discussed. We go on to explore the events, which offered the decision makers opportunities to update their beliefs about the scope of design right protection. We find that filing motives changed from specific protection goals to freedom to operate over time. We also find that the actors faced several, but sometimes contradictory, learning opportunities. There are two types of learning relating to the usage of design rights: 1) learning…
