Conflict Mitigation

AbstractLarge-scale engineering projects typically involve many different types of professionals who must interact and communicate with one another. This interaction produces conflicts that need to be resolved. A framework is presented in which the rationale used in a collaborative design environment for designing an artifact is also used for conflict mitigation. The framework contains mechanisms for checking interactions and prompting hypotheses about the reasons for the interactions. These hypotheses, once verified by the designers, improve conflict resolution by assisting them in coordinating and negotiating conflicts. This, in turn, enhances communication during the design process and consequently increases productivity in the engineering industry.

Successful collaborative design requires in-depth communication between experts from different disciplines. Many design decisions are made based on a shared mental model and understanding of key features and functions before the first prototype is built. Large-Scale Immersive Computing Environments (LSICEs) provide the opportunity for teams of experts to view and interact with 3D CAD models using natural human motions to explore potential design configurations. This paper presents the results of a class exercise where student design teams used an LSICE to examine their design ideas and make decisions during the design process. The goal of this research is to gain an understanding of (1) whether the decisions made by the students are improved by full-scale visualizations of their designs in LSICEs, (2) how the use of LSICEs affect the communication of students with collaborators and clients, and (3) how the interaction methods provided in LSICEs affect the design process. The results of this research indicate that the use of LSICEs improves communication among design team members.

Abstract Collaborative engineering involves multiple engineers and managers working together to develop engineering products. As the engineering problems become more and more complicated, new technologies are required to achieve better effectiveness and efficiency. While process models management and technologies have been developed to support engineering design, most of them apply only to routine design tasks and do not explicitly deal with the change of processes during execution. Our research proposes a process-driven framework to support collaborative engineering. The framework is composed of a process model that captures both high level and low level activity dependencies, an agent network that monitors process execution and facilitates coordination among engineers, and a Petri-net based modeling tool to represent and analyze process features and predict the performance of engineering processes. In this paper, we first describe a simple collaborative design problem and our proposed ActivePROCESS collaborative engineering framework. After that we present our Petri-net based analytical model of collaborative design process and discuss the model along with a case example.

Abstract Shape modeling plays a vital role in the design process but often it is the most tedious task in the whole design cycle. In recent years the Computer Aided Design (CAD) industry has evolved through a number of advances and developments in design methodology. However, modeling in these CAD systems requires expertise and in-depth understanding of the modeling process, user interface and the CAD system itself, resulting in increased design cycle time. To overcome these problems a new methodology and a system called “Detailed Virtual Design System” (DVDS) has been developed for detailed shape modeling in a multi-modal, multi-sensory Virtual Environment (VE). This system provides an intuitive and natural way of designing using hand motions, gestures and voice commands. Due to the lack of effective collaborative design, visualization and analysis tools, designers spend a considerable amount of time and effort in the group discussion during design process. To enable multiple designers to effectively and efficiently collaborate in a design environment, framework of a collaborative virtual environment, called “Virtual Environment to Virtual Environment” (V2V), has been discussed. This framework allows same site and remote site multi-modal, multi-sensory immersive interface between designers.

Engineering Systems

The complexity of engineering systems is rapidly increasing because the number of components has increased and various engineering disciplines are involved. According to this trend, large-scale engineering systems are designed by multiple design teams with many designers of various disciplines. Although the design process by the design teams is a great deal similar to the design process by an individual designer, there is an important difference between them. Designing a large-scale engineering system with design teams can cause potential conflict among the subsystems because each team may design a subsystem without considering the other team’s subsystems. In this article, a collaborative design process is proposed to design a large-scale engineering system efficiently without the conflict among the subsystems using the Independence Axiom of axiomatic design. The proposed process uses a zigzagging process between the functional domain and the physical domain, and the online electric vehicle (OLEV) is designed by the proposed process. The OLEV is an electric vehicle which uses electric power transmitted wirelessly from the power source buried in the road. The functional requirements (FRs) and constraints of the OLEV are specified to clarify the design objectives and specifications. The prototype, which is designed by the design teams based on the defined FRs, is evaluated using the proposed process. It is found that the proposed process can lead design teams to design a product more efficiently without unnecessary iterations.

Design Options

A set-based multiscale and multidisciplinary design method has been proposed in which distributed designers manage interdependencies by exchanging targets and Pareto sets of solutions. Prior research has shown that the set-based method (SBM) has the potential to reduce the number of costly iterations between design teams, relative to centralized optimization approaches, while expanding the variety of high-quality, system-wide solutions. These results have been obtained with representative examples in a laboratory setting. The goal of this research is to investigate whether similar results are obtained from an industrial trial, implemented in an industry design environment. The SBM is applied to the design of a downhole module for our industrial partners at Schlumberger, a developer of oilfield tools and services. The design was conducted on location at Schlumberger by an intern who converted the existing Schlumberger design process into a set-based design process. Results indicate that the SBM delivers the benefits predicted in the laboratory, along with a host of advantageous side effects, such as a library of back-up design options for future design projects.

Resolution Strategy

Shortcomings of current conflict resolution methods in solving the problems of disordered competition for design resource in networked design environment are analyzed. By introducing the design structure matrix (DSM) to the planning process of design task, a mathematic description model in collaborative design considering the conflict causes as resource conflict, process conflict and design conflict is given. The reconstruction method of the DSM as well as the DSM based matrix search algorithm is given, based on which the problem of design locking and long waiting because of limited resource in the collaborative design process can be successfully solved. Finally, the design of a bridge crane is used as an example to demonstrate the successful application of the proposed resource conflict resolution strategy in collaborative Design environment.

Managing the product realization process is a difficult endeavor in today’s global product development environment. Design project managers are required to form teams from geographically distributed designers as well as effectively manage the collaborative design process. In this paper, a computational method is proposed to aid design managers in allocating design tasks to geographically distributed designers and identify appropriate coordination mechanisms to manage the collaborative design process. The method involves three stages: i) arriving at an initial design task sequence using the design structure matrix through partitioning of design tasks into blocks of dependent, independent and interdependent tasks, ii) allocating of design tasks to design teams and the improvement of the design sequence accounting for the number of designers available and their competencies and iii) determination of design review meeting frequencies as a coordination mechanism for interdependent tasks using agent based modeling simulations.
