Actively involving participants in business process modeling enables integration between elicitation and modeling steps of the BPM lifecycle. Such integration may lead to a more efficient design procedure and ultimately to a more accurate representation of the business process. However, active involvement of process participants creates several challenges, as the latter are not expected to have modeling skills. The purpose of this paper is to present a business process design approach, called CoMPArE /WP, which tightly integrates the elicitation and modeling stages of process design, through the active involvement of process participants. To achieve effective involvement of process participants, CoMPArE/WP adopts the principles of natural modeling. However, being a business process design approach aiming at supporting the whole BPM lifecycle, CoMPArE /WP deals also with the transition of natural modeling to formal process representations that can be enacted using a BPMS.

Nowadays, industries face very strong challenges because of the high competitiveness between them. In fact, they are required to offer products with high quality and minimum cost in the minimum time. Since most of the characteristics and costs of the product and its manufacturing process are fixed in the design phase, this paper is focused on this strategic phase. Indeed, a new integrated product design approach is presented. It considers at the same time design requirements, materials characteristics, manufacturing parameters and the assembly process specifications. The developed approach is quantitative. Actually, the decision making is based on all its steps on objective and subjective indicators. To validate the integrated approach, a case study on the Schrader Robot is developed. This application allows to choose the most appropriate materials, manufacturing processes and assembly solution of its different components.

Multilevel design is a subset of engineering design in which design problems are defined and analyzed at various levels of model complexity or resolution. Due to the potential for propagated uncertainty in a multilevel design process, design goals for maximizing system robustness to uncertainty in noise and control factors are included in the Blast resistant panels (BRP) design process. Blast resistant panels (BRPs) are sandwich structures consisting of two solid panels surrounding a honeycomb core. Under impulse loading, BRPs experience less deflection than similarly loaded solid panels of equal mass due to core crushing. In order to manage complexity in BRP concurrent product and materials design, a multilevel design approach is proposed. Additionally, in order to collect and store BRP design information in a modular and reusable format, a template-based design approach is implemented in BRP multilevel design. In this paper, a generic multilevel design template based on existing design methods (the compromise Decision Support Problem and the Inductive Design Exploration Method) is presented. The multilevel design template is then particularized and applied to BRP preliminary design, highlighting the advantages of a templatebased approach to multilevel design.

This article introduces the design and the experimental validation of the Trackhold, a novel mechanical motion-tracker for upper limb physical rehabilitation. The Trackhold is based on a passively balanced mechanism that can approximately relieve the weight of the patient’s arm regardless of the position. The system features a novel kinematic architecture with large workspace and custom developed joint sensors providing accurate real-time measure of the upper limb posture. The design approach of the device, which went through kinetostatic and dynamic analyses, is presented and details on the employed mechatronic solutions are provided. A prototype of the Trackhold has been fabricated and functionally validated.

Abstract In team-based concurrent product and process design (CPPD), one type of team activities proceeds alternately in a one-by-one fashion. This sequential mode of design flow can be treated as a generalized leader/follower team paradigm, in which the leader acts as a principal team and the follower as a subordinate team. In the dual-team approach, the leader and the follower correspond to two aspects of CPPD — product design and process design — whereby the alternate nature of design tasks can be characterized through the interactions of the leader and the follower. To reveal the variety of such team activities, the notion of responsibility and controllability in various design protocols is introduced to describe the respective roles of the leader and the follower in team design. The method of Design for Satisfaction (DfS) is used as a framework to characterize team’s preference toward a feasible design in view of the team’s goal. Accordingly, the satisfaction-driven dual-team based CPPD models are developed to account for different team scenarios. A design example is used to support the illustration of the team design approach suggested.
