【摘要】：摘要：云制造是一种面向服务的网络化制造新模式,它为中国制造业的服务化转型提供给了一种新的思路。为促进云制造的落地实施,本文以云制造环境下的设计阶段作为研究对象,提出了一套面向设计资源的服务化理论与方法,实现云制造环境下不同种类设计资源的服务化接入和服务化接出,提供有力的设计问题求解环境和基于服务的设计资源运用方式。本文首先根据设计资源的形成关系,将其分为智力资源、知识资源、工具资源和设计能力四类。提出采用设计资源服务化平台作为这四类资源的集成共享平台,给出了平台的结构组成及特点。进一步提出了基于联邦元计算的设计资源服务化框架,为构建具有易用性、弹性和自管理性的设计资源服务化平台提供支持。描述了基于服务的设计资源运用方式,制造企业不仅可以动态地加入和撤离设计资源服务化平台,还可以以服务的形式使用资源,而无需考虑底层的具体资源。为实现设计资源服务化平台下各类资源的服务化接入和服务化接出,进一步开展了以下三个方面的研究工作。 (1)根据设计资源的特点,采用SOOA (Service Object-Oriented Architecture,面向服务对象的体系架构)作为底层的服务架构,提出了一种基于SOOA的设计资源服务化方法,研究了其中三项技术：设计服务接口、设计资源服务化策略和设计服务动态供应,通过接口定义、资源封装和动态供应三步,将不同种类的设计资源动态供应为具有标准化接口和SOOA特点的设计服务,为设计资源的服务化接入提供支持。 (2)为实现设计资源的规范、快速封装,提出了一种基于服务模板的设计资源封装方法,给出了服务模板的定义、结构、类型及描述语言,描述了其中的服务抽取和服务封装两个过程。该方法不仅可以加快、规范设计资源的封装工作,还可以将已有的设计服务程序抽取为不同类型的服务模板加以重用。设计工程师无需编程就可以将设计资源封装为设计服务。 (3)开展了联邦元计算环境下设计资源管理方面的研究,提出了基于QoS (Quality of Service,服务质量)和SLA (Service-Level Agreement,服务等级协议)的设计资源管理模型,给出了该模型中的SLA规范和QoS规范,并建立了SLA对象模型。根据服务请求中的QoS要求,通过基于SLA的服务资源动态协商过程,为服务请求方配置或动态供应满足QoS要求的服务资源,为制造企业接出高质量的设计服务提供支持。最后,为了对本文提出的服务化框架及方法的有效性实用性进行验证,设计开发了面向高速机车结构设计的设计资源服务化平台,并在该平台下开展了CRH2车轴轻量化设计实例的运用,实现了实例所需四种资源的服务化接入和服务化接出。前期工程应用显示,设计资源服务化平台为用户提供了有力的设计问题求解环境和基于服务的设计资源运用方式,有效地缩短了服务双方的交接周期。
[Abstract]:Abstract: Cloud manufacturing is a new service-oriented network manufacturing model, which provides a new way for the service transformation of China's manufacturing industry. In order to promote the implementation of cloud manufacturing, this paper, taking the design stage of cloud manufacturing environment as the research object, puts forward a set of service theory and method for the design resource, and realizes the service access and service of different kinds of design resources under the cloud manufacturing environment. It provides a powerful design problem solving environment and a service-based design resource application mode. First of all, according to the formation of the design resources, it is divided into four parts: intelligence resource, knowledge resource, tool resource and design ability. In this paper, the design resource service platform is used as the integrated sharing platform of the four types of resources, and the structure and the structure of the platform are given. Point. The design resource service framework based on the federated meta-calculation is further put forward, which provides support for the design of the design resource service platform with ease of use, elasticity and self-management. A service-based design resource application mode is described. The manufacturing enterprise can not only dynamically join and evacuate the design resource service platform, but also use the resources in the form of service without considering the specific material of the bottom layer In order to realize the service access and service of various kinds of resources under the design resource service platform, the following three aspects are further carried out: In this paper, based on the characteristics of the design resources, the service architecture of SOOA (Service Object-Oriented Architecture) is used as the service framework of the bottom layer, and a service method of design resource based on SOOA is proposed. The service interface of the meter, the design resource service strategy and the design service dynamic supply, through the interface definition, the resource encapsulation and the dynamic supply three steps, the different kinds of design resources are dynamically supplied to the design service with the standardized interface and the SOOA characteristic, and the service connection of the design resources In order to realize the specification and fast encapsulation of the design resources, the design resource packaging method based on the service template is proposed, and the definition, structure, type and description language of the service template are given, and the service extraction and service are described. the method not only can accelerate and standardize the encapsulation of the design resources, but also can extract the existing design service programs into different types of clothes The traffic template is reused. The design engineer can use the design resources without programming In this paper, a design resource management model based on QoS (Quality of Service, Service Quality) and SLA (Service-Level Agreement) is presented, and the SL in this model is given. A Specification and QoS Specification and Built the SLA object model is established; according to the QoS requirement in the service request, the service resource satisfying the QoS requirement is configured or dynamically supplied to the service requester by the service resource dynamic negotiation process based on the SLA, and high quality is connected for the manufacturing enterprise Finally, in order to verify the validity and practicability of the service framework and method proposed in this paper, a design resource service platform for the structural design of the high-speed locomotive is designed, and the CRH2 vehicle is carried out under the platform. The application of the weight-weight design example of the axle realizes the four kinds of resources needed by the example. The pre-engineering application shows that the design resource service platform provides the user with a powerful design problem solving environment and a service-based design resource utilization mode, and is effectively scaled down.
