【摘要】：随着市场经济的发展,用户的需求也已转变为个性化以及多样化。面对用户需求的变化,企业也要提高自身快速响应的能力,以便能更快更好地满足用户的要求。同时,随着计算机技术在制造业中的应用,企业实施信息化管理已成为一种必然趋势。信息化管理不仅能够使企业可以全面实时掌握内部信息,还可以使企业不同部门之间实现信息的共享,加快产品的研发制造速度,从而对市场的变化做出快速的响应。工艺资源作为企业信息化的基础资源,是产品研发和制造过程中重要的基础数据。对于叶片产品,由于它的个性化以及复杂性,使其在制造过程中会大量用到不同的工艺资源。因此,开发叶片工艺资源数据库管理系统,不仅可以对企业现有的工艺资源进行有效的管理,使企业对工艺资源状况进行整体的把握,还可以方便工艺人员快速查找到各个产品在制造过程中用到的工艺资源以及工艺资源的实时状况,从而提高工艺规程编制的速度和质量。本文以无锡某叶片制造公司为背景,结合该企业工艺资源的使用状况,做了以下工作: 首先,将企业内的工艺资源进行分类,根据不同种类工艺资源包含内容的不同,通过面向对象技术,将每类工艺资源的属性信息进行抽象,构建工艺资源的局部E-R模型。同时,根据工序与工艺资源之间的关系,将工序进行抽象,通过工序实体建立基于叶片制造流程的全局E-R模型。其次,根据产品在不同阶段的生产状态,构建叶片产品的树形模型,同时将不同阶段的制造工序以及每道工序中使用的工艺资源融入进去,构建产品、工序和工艺资源的树形模型,实现不同产品通过工序对工艺资源进行有效管理。最后,开发了叶片工艺资源数据库管理系统和数据库设计,并对系统的各个功能模块进行了简单的介绍,通过各个模块实现工艺资源基本信息的存储和管理,以及通过工序对工艺资源进行结构化管理,方便维护和查看工艺资源信息,实现工艺资源信息共享。
[Abstract]:With the development of market economy, the needs of users have changed into individuation and diversification. Faced with the change of user's demand, enterprises should improve their ability to respond quickly so as to meet the requirements of users more quickly and better. At the same time, with the application of computer technology in manufacturing, information management has become an inevitable trend. Information management not only enables enterprises to grasp internal information in real time, but also enables enterprises to share information among different departments, accelerate the speed of product development and manufacture, and thus make a rapid response to the changes in the market. Process resources, as the basic resources of enterprise informatization, are important basic data in product development and manufacturing process. For blade products, due to its individuation and complexity, many different process resources are used in the manufacturing process. Therefore, the development of blade process resource database management system can not only effectively manage the existing technological resources of enterprises, but also make the enterprises grasp the status of process resources as a whole. It is also convenient for the process personnel to find out the process resources and the real time status of the process resources used in the manufacturing process of each product, so as to improve the speed and quality of the process planning. Based on the background of a blade manufacturing company in Wuxi, this paper has done the following work in combination with the use of technological resources in this enterprise: Firstly, the process resources in the enterprise are classified. According to the different contents of different kinds of process resources, the attribute information of each process resource is abstracted by object-oriented technology, and the local E-R model of process resources is constructed. At the same time, according to the relationship between process and process resources, the process is abstracted and the global E-R model based on blade manufacturing process is established through process entities. Secondly, according to the production state of the product at different stages, the tree model of the blade product is constructed. At the same time, the manufacturing process in different stages and the process resources used in each process are integrated into the product, and the product is constructed. The tree model of process and process resources can realize the effective management of process resources by different products. Finally, the database management system and database design of blade process resources are developed, and the function modules of the system are introduced briefly. The basic information of process resources is stored and managed by each module. And through the process of process resources structured management, easy to maintain and view process resources information, realize the sharing of process resources information.
