“…The focus of the paper is on the student survey, where challenges and shortcomings in the method proposed by Safavi et al (2016) to students to facilitate the implementation of MDO within their projects are listed and will be addressed in the proposed guideline. This information is generated from a Masterlevel course at Linköping University.…”

This study provides a method to construct a collaborative multidisciplinary design optimization (CMDO) framework to be used in conceptual analysis of a complex engineering product. As its named implies, the CMDO framework, should be developed through the joint efforts of a team. Both technical and collaborative aspects should therefore be taken into account to provide a generic guideline. The proposed guideline to facilitate CMDO implementation in conceptual design is based on information gathered from a course project that included 40 students at Linköping University. An exploratory approach is used to clarify the technical/collaboration challenges, including questionnaires and extensive interviews with students. The guideline has been established to handle the challenges and difficulties of MDO implementation. It provides a handbook (step-by-step) approach to realize a CMDO framework in conceptual design. Preliminary results include an ontology to enable the use of CMDO, the collaboration strategy and a generic guideline.

“…The person responsible for each task should manage the team for the tasks to be performed effectively. Figure 2 shows the guideline presented by Safavi et al (2016), which was delivered to the team members during the course. The group should then follow the guideline to develop an MDO framework.…”

“…In addition, Fujita and Yoshida (2004) develop a product variety optimization model for module combination and module attributes of multiple products. In this context, multidisciplinary design optimization has been used especially for complex systems (Brevault et al, 2018;Safavi et al, 2016). The use of single-objective models in the literature can be classified into technical design optimization, generic design and sustainable design.…”

Design is a process through which customer needs are transformed into product or service specifications, and then used to develop a model or prototype. The prototype is tested, and modifications are brought to it before the production process starts. Moreover, the design process may be divided into different stages, starting from the definition of the customer needs, going through the conceptual design phase and ending up with the detailed design. In this article, we address the conceptual design phase, where the customer needs are assumed to be known. The proposed approach considers, based on customer needs, primary and secondary design criteria. Each design criterion has a set of predetermined possible values (options) from which the designer may select. Making the best selection of all the design features while satisfying the customer needs in terms of cost, quality (customer preference) and environmental performance is a combinatorial problem and therefore a decision-making framework would be helpful for the designers. In this article, the design criteria are evaluated using fuzzy technique for order preference by similarities to ideal solution based on cost, quality and environmental sustainability. A multiobjective and a single-objective binary programming models are then developed and solved, and their optimal solutions are obtained. The multiobjective solutions provide the decision makers with the possible trade-offs, whereas the single-objective model solution can be used as a final decision-making tool. The proposed approach is implemented in a user-friendly software developed by the authors. A case study is conducted using a baby car seat for which three main and six secondary design criteria are considered. The obtained results show the effectiveness of the approach used.

“…Concurrent engineering also made large impact in the automotive, electronics, and computer industry in particular by supporting integrated product development spanning over different disciplines and lifecycle phases (Prasad, 1995, 1996). By today, the methodology of concurrent engineering is applied to conceptual design also in various industries and gets combined with multidisciplinary design optimization (MDO) (Reysset et al, 2015; Safavi et al, 2016).…”

This work presents a method and a tool for conducting conceptual design studies for projects such as a space exploration mission and a satellite constellation in a concurrent manner in both time and space, while taking into account the structure of the system to design and the dependencies between the system's constituting elements. Design work is parallelized to reduce the time required to converge to a solution for a preliminary design, which includes the system architecture, its detailed requirements, and its costs. The multidisciplinary team of designers works in colocation to leverage effective direct human interaction for discussing design trade-offs quickly. While this is practice in space agencies for mission feasibility studies, a common methodology was not described so far. Our work proposes a method for the coordination of discipline experts and the sequence of activities performed during conceptual design studies, which use integrated parametric system models. Our method reduces the number of design iterations by applying a design structure matrix clustering algorithm to the system model and deriving a schedule for the design session. We also describe the tool Concurrent Engineering Data Exchange Skoltech we developed for collaborative work on the parametric system models and serve as an instrument for research on complex system design methodologies. The tool features a fast synchronization mechanism for the concurrent work of multiple design experts, and it supports our coordination method for concurrent design studies. The tool was published as open-source software, so other researchers can use it and build upon it. We used our tool and applied the method to two case studies of preliminary satellite designs and tested them with groups of students of a satellite engineering class and researchers from our institute. Throughout the experiments, we recorded information about user interactions and collected user feedback for the evaluation of the coordination method and the collaboration tool. Both method and tool demonstrated their validity in our experimental setting.
