AbstractIn recent years, space projects have evolved to faster and more variable projects. To adjust the design processes in accordance, new work methodologies arise, as the Concurrent Engineering (CE). This working discipline is characterized by collaborative design and the flux of information being improved by working in a dedicated environment. CE has been recently adopted by space industry for the preliminary design phase of spacecrafts and other space systems. However, this methodology does not envisage tasks prioritization, which is a fundamental aspect to achieve an optimal design solution with an efficient allocation of resources. In this work a variation of CE discipline by applying Agile methodologies (in which the aspect of task prioritization is essential), is proposed. Agile methodologies allow the proper distribution of the design effort depending on the project priorities, the state of the design and the requirements, in a continuous process to improve the design solution. The general aspects of the proposed method are presented and applied to the design of a space mission, the results being analysed and compared with to the classical CE process in order to outline its differences and similarities with CE and Agile methodologies and show its potential for a new environment for space project design.

Lifecycle Management

The shift from sequential to concurrent engineering has led to changes in the way design projects are managed. In order to assist designers, many effective tools have been developed to support collaborative engineering. Nowadays, industrial scenarios encourage companies to adopt product lifecycle management solutions, even if they may not be able to understand their benefits. Indeed, product lifecycle management roadmap is quite difficult to implement and return on invest can take time. Moreover, many free solutions with comparable functionalities are developed, which have been increasingly successful. In this article, we test different configurations of software to make a comparison between free software and market solutions. In this experiment, 72 students in a Master’s degree course aimed to design mechanical products by using dedicated software to assist collaborative distributed design, using two different configurations: free and commercial solutions. The research question to be solved is: as engineering educators, what is the most efficient way to train our students to collaborative distributed design? This experiment allowed us to compare design functionalities between the two configurations, in order to determine ways to improve efficiency in a collaborative distributed design situation. Finally, the feedback generated in this experiment allowed us to adapt training practices in engineering education.

Opening Up

The role of collaboration in the realm of social creativity has been the focus of cutting edge research in design studies. In this paper, the authors investigate the role of collaboration in the process of creative design and propose a computational model of creativity based on the newly proposed meta-design approach. Meta-design is a unique participatory approach to design that deals with opening up of design solution spaces, and is aimed at creating a viable social platform for collaborative design. A meta-design-based collaborative approach to the design process may achieve ET-creativity by expanding the conceptual space of design beyond what would have been possible by individual, non-collaborative design. The model has been implemented using interactive genetic algorithms, which casts the design problem as an optimization problem and uses a set of collaborative users for subjective fitness evaluation. The design problems investigated include the collaborative design of architectural floorplans and editorial design of brochures.

The collaborative design and manufacturing is applied in the aircraft industry. This paper introduces the collaborative design and manufacturing mode in aircraft industry and presents its structural framework. The data is managed in the structure of BOM and there are two ways to share the data between the suppliers. The collaborative design and manufacturing process reflects the concept of concurrent engineering. The collaborative design and manufacturing system has been applied in the project of C919 which could sharply shorten the research cycle and reduce the product cost.

Agile Approach

Research in the late 80´s on technological companies that develop products of high value innovation, with sufficient speed and flexibility to adapt quickly to changing market conditions, gave rise to the new set of methodologies known as Agile Management Approach. In the current changing economic scenario, we considered very interesting to study the similarities of these Agile Methodologies with other practices whose effectiveness has been amply demonstrated in both the West and Japan. Strategies such as kaizen, Lean, World Class Manufacturing, Concurrent Engineering, etc, would be analyzed to check the values they have in common with the Agile Approach.

Target Value Design

Target value design is a new practice in the construction industry promoting concurrent engineering and collaborative design. This paper shows the results of literature survey to identify the influencing factors in the target value design. The paper also presents the results of a questionnaire survey to explore the industry practitioners' perception of the relative importance of the influencing factors. Project stakeholders participating in the survey consider the integration of different project stakeholders in the design phase as critical. The project definition is also regarded as essential in implementing the target value design. However, the market conditions and project attributes are considered as least significant in the target value design process.

<div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p>Icarus is a mission concept designed to record the activity of an asteroid during a close encounter with the Sun. The primary science goal of the mission is to unravel the nontrivial mechanism(s) that destroy asteroids on orbits with small perihelion distances. Understanding the destruction mechanism(s) allows us to constrain the bulk composition and interior structure of asteroids in general. The Icarus mission does not only aim to achieve its science goals but also functions as a technical demonstration of what a low-cost space mission can do. The proposed space segment will include a single spacecraft capable of surviving and operating in the harsh environment near the Sun. The spacecraft design relies on the heritage of missions such as Rosetta, MESSENGER, Parker Solar Probe, BepiColombo, and Solar Orbiter. The spacecraft will rendezvous with an asteroid during its perihelion passage and records the changes taking place on the asteroid’s surface. The primary scientific payload has to be capable of imaging the asteroid’s surface in high resolution using visual and near-infrared channels as well as collecting and analyzing particles that are ejected from the asteroid. The payload bay also allows for additional payloads relating to, for example, solar research. The Icarus spacecraft and the planned payloads have high technology readiness levels and the mission is aimed to fit the programmatic and cost constraints of the F1 mission (Comet Interceptor) by the European Space Agency. Considering the challenging nature of the Icarus trajectory and the fact that the next F-class mission opportunity (F2) is yet to be announced, we conclude that Icarus is feasible as an F-class mission when certain constraints such as a suitable launch configuration are met (e.g., if EnVision is selected as M5). A larger mission class, such as the M class by the European Space Agency, would be feasible in all circumstances.</p> </div> </div> </div>

Model Based

The point-based approach consists of committing a set of requirements and a single design solution from the design space. This approach is time-consuming and often leads to deadline excess when developing a new complex system such as mechatronic systems. In fact, this approach could generate iterative loops between engineers in the downstream design stage to evaluate the manufacturability and the quality of the developed system. To overcome this issue, introducing a model-based system engineering (MBSE) approach in the upstream design stage hinged on set-based concurrent engineering (SBCE) principles is a good solution to diminish the exchange loops between engineers and to enhance efficiency in the design process. This approach consists in evaluating a large set of system solutions, then gradually narrowing these solutions until converging to a limited set of optimized solutions. In this article, a novel approach entitled “Model based for reliability and manufacturability analysis (MBRMA)” and based on model-based system engineering and set-based concurrent engineering in the preliminary design phases is used to filter out weak or costly solutions over time and to assess system engineer when adopting trade-off analysis. First, customer requirements, functional and structural aspect of the system are defined using SysML diagrams. Next, the application of the algorithm allows narrowing the design space, and finally, a trade-off analysis is carried out to select the best system architecture. The first contribution of this article is the creation of novel stereotypes of composition and allocation flows in a profile diagram between functions and alternative solutions. The second contribution is the implementation of an algorithm to analyze system robustness and to converge on the final set of optimized solutions. To test this newly developed model “model based for reliability and manufacturability analysis (MBRMA),” a case study of an air conditioning electrical compressor is considered to illustrate the various stages of this concurrent engineering approach.

An important requirement for a collaborative design platform in Concurrent Engineering (CE) is the integration of various engineering software tools and utilities in product design and development. Some CE platforms based on a client/server architecture or static Service Oriented Architecture (SOA) are available in the marketplace, but they lack flexibility and reliability in the constantly changing Internet environment due to the dynamic nature of the network. Based on the current development of SOA, this paper presents a Service-oriented Collaborative Design platform (SCoD) based on SORCER—a dynamic SOA infrastructure that allows federated integration of engineering software components in CE environments. The architecture of SCoD is proposed, the wrapping methodology used to integrate engineering software tools in SCoD is presented, and the federated method invocation for services in SCoD is described. With the support of SCoD, collaborative design in CE environments can be deployed, and scalability, reliability, and flexibility can be achieved in the changing Internet environment.
