项目摘要

In general, pre-production work is a non-routine work and much depends upon inherent technologies of the person in charge. It is necessary to share and inherit important information in natural form. In this study, requirements for pre-production supporting information system have been summarized. Then, a methodology has been developed to register background information for decision making in addition to formal information as a database and relate it to activity model and CAD system. Activity model is a model of entire production activity which include various elements of working procedure or person in charge, negotiation, environment, background of decision making and so forth. Here, activity model is considered to implement for practical use and an infrastructure-like software has been developed. The activity model can be loaded in the combination of three elements such as hierarchical task model, design items to be determined in each work level (like shape, working condition or specification) and background information related to each design item. These three elements are arranged in the manner where they can be freely registered or changed and their mutual relationship can be modified or dynamically constructed. Thus, an integrated system was developed in which this activity model and multi-media database and further, CAD are combined. All contents of operation are accumulated as log information and determined values are accumulated as a part of product information. Through the above arrangement, it became possible to select effective background information like frequently used information or the basis to obtain reliable quality. Relationship between the determined value and the applied background information used to determine it is referenced when the ground of the production design is perused while it is also used to check whether determined value contains any error. It should be possible to revise and improve production design standard using this system.

一般来说，前期制作工作属于非常规工作，很大程度上取决于负责人的固有技术。有必要以自然形式共享和继承重要信息。本研究总结了预生产支持信息系统的需求。然后，开发了一种方法，将除了正式信息之外的决策背景信息注册为数据库，并将其与活动模型和 CAD 系统相关联。活动模型是整个生产活动的模型，包括工序或负责人、谈判、环境、决策背景等各种要素。在这里，活动模型被考虑实施以供实际使用，并且已经开发了类似基础设施的软件。活动模型可以以分层任务模型、每个工作级别中要确定的设计项目（如形状、工作条件或规格）以及与每个设计项目相关的背景信息等三个元素的组合来加载。这三个元素的排列方式可以自由注册或更改，并且可以修改或动态构建它们的相互关系。因此，开发了一个集成系统，其中该活动模型与多媒体数据库以及 CAD 相结合。所有操作内容都作为日志信息累积，确定值作为产品信息的一部分累积。通过上述布置，可以选择有效的背景信息，例如频繁使用的信息或获得可靠质量的基础。确定值与用于确定该确定值的应用背景信息之间的关系是在仔细研究生产设计基础时参考的，同时也用于检查确定值是否存在误差。使用该系统应该可以修改和改进生产设计标准。
