Keywords- ; engineering; collaborative design process design I. INTRODUCTION Development of complex products is an extremely rigorous and systematic project involving structures, dynamic simulation, electromagnetic, pneumatic, and other subsystems, each subsystem belong to different research institutions, and each research institution relies more assisted units support. Such a huge project, needs a massive transregional cross-sectoral collaboration, and system integration, coordination, research and design process, often pass through several iterations to get optimum comprehensive general scheme [1]. With the increase of product types, traditional design platform do not meet current design requirements, it is necessary to combine the existing development workflow and platform, developed on this basis can support advanced research, design, manufacturing engineering systems for specific applications, while building in Hall for workshop of model, task, process, Index, represented by communication environment, collision and confrontation of ideas through technical innovation, promoting the integration of and business processes, support a new generation of innovative design and overall design for complex products. II. DEMAND ANALYSIS For the realization of complex product collaborative design and optimization, the system must meet the following main functions: A. d task In the process in Task Manager, you can reuse resources, according to design business processes, similar tasks and processes in the and resources are pushed onto the task process node. B. Multi-source acquisition technique Multi engineering can be divided into documents and text classes, model category, experience, tools, etc, for multi-source engineering of the distribution and characteristics of acquisition in different ways, and encapsulates the resources into a unified model of, stored in the repository. C. d design process In the design process of complex products, according to user needs to retrieve similar cases and improved to enhance design reuse, mainly through discovery, organization and extraction, model construction method of design process precipitation [2-4]. Meanwhile, can also design iteration process in design/simulation of generating data and resources; promotion of design concepts,, accumulation of specification reuse, inheritance, and drive [5], and with the stored in the corresponding (including the,, model, process, etc). D. Design-activity-d -correlation technologies In the design process, by means of push technology will push resource to designers in the work environment, and to monitor progress in the design process. III. SYSTEM DESIGN For complex product design process, d on the methodology of systems engineering and engineering, building cooperative design system framework and realization of collaborative design d on. A core of collaborative design, driven by, building a modern, intelligent and integrated product design system and capacity to meet product life cycle collaboration, refinement, needs, significantly improving product design capabilities. A. General framework Of complex product collaborative design platform d on by the application layer, function layer, layer and data layer, as shown in Figure 1.

System technical architecture

3 Application layer: uses the system for all types of users, collaborative design process includes mission planners, monitors, general staff,, platform maintenance and personnel, and so on. Portal users through a unified design system in accordance with their respective projects and technical role permissions use a functional system design platform, carry out related work. Functional : the core, through project, system, ( community), integrated module for the application layer provides the capability to support different designers. Support layer: a system-wide basis, through large data processing and ontology technologies, data mining, the process engine, data, role, life cycle, extensible interface functions. The data layer is a system resource pools for all types of users with collaborative design process requires the, data and documentation, including models, rules,,, experts, process library, ontology, and so on. B. Technical Architecture Technology architecture is the technical realization of functional architecture. This system will be d on large data technology, push, ontology to achieve collaborative design system d on. Technical architecture, primarily through discovery ( extraction), ( of storage), ( push) technology to achieve, organization, and use of iterative processes, the technical architecture of the system is shown in Figure 2. (1) discovery Hall for workshop of the project through " Board" recorded during the discussion in the form of ideas, views and solutions to achieve discussion of tacit mining. Task, indicators of need, and the process process through product requirements and analysis process, the entire process using support resources, constraints, resources are stored. Finally, extraction, resources, and realize the tacit explicit. (2) Management In order to achieve unity of multi-source engineering interact, store to facilitate subsequent collaborative design platform d on for application, need to establish unified applied to multi engineering acquisition model UKM (Unified Model). The so-called UKM, which is the source of resources,, business process, upload, environment, of metadata according to a certain logic rules the unified organization of the model, it can be d on, sources, business processes, people, characters and other elements of view freely. UKM to ensure the model class, and the text of the document class, experience, and tools description of resources, while ensuring that the view corresponds to a different type of resources. (3) Services Task, indicators of demand and the decomposition stage, through discovery and push technology, demand, map, go back in, under project name, type content, target and content, pushing demand indicators from the related to standards, methods, guides the user through demand and target decomposition. C. Key technology 1) Base construction method d on design process Collaborative complex product development process involves a great deal of, sharing, and innovation, and is scattered on each node of the design process, with different categories and formats. In this paper, d on the design process and method research of heterogeneous acquisition; d on the unified model of organization systems, from the perspective of reuse, integrate dispersed resources, through a rational organization and packaging, form a unified, logically structured, to achieve orderly and controllable, accessible State. For the proof of concept, requirements analysis, design, multidisciplinary collaborative design processes such as design, test, process category, model, tool, data categories, such as document refinement of and curing.

For such complex systems engineering, will involve a lot of. Therefore, in the process of collaborative design, analyzing the characteristics of design and design activities and work, using push technology pushes resource to the design environment. Design and design activities through already-established Association between using feature index matching design of associated with the dynamic design process, supporting product collaborative design activity, laying the Foundation for navigation for collaborative design activities. 3) Design results d of technology Design for complex products, key resources, extraction and presentation methods, relying on the project, and key resources, forming a clearer, more comprehensive shows prototype system construction, and combs the key to universal extraction and presentation. To tease out objects, resource evaluation method, considering the factor, the is applied and the contributing factors of creation, quantitative evaluation model of resources, including index and weight set. On this basis, further research on resource valuation models, including the model elements, organization and methods of evaluation, promotion resources quantitative evaluation of curing, high-value sharing and reuse. IV. CONCLUSION From the angle of systems engineering and engineering, analysis of complex product collaborative design process support. Through needs analysis proposed collaborative design system d on architecture, describes the technical architecture of the system and its key technologies.
