【摘要】：灰色系统理论是我国学者邓聚龙教授于1982年提出的一门全新的学科,它旨在研究“部分信息已知,部分信息未知”的不确定性系统,是通过对“部分”已知信息的生成、开发,实现对现实世界的确切描述和认识。所谓灰色系统,泛指信息不完全的系统。客观来讲,人们所认识到的世界都是由“灰色系统”组成的。由于万事万物的普遍相联性,所以系统普遍存在与人们的生活中;又因为人们认知的局限性,因此,在处理实际问题时,人们习惯于忽略其实会对结果造成影响的未知因素,进而使得人们将灰色系统当作白色系统进行处理。因此,灰色系统其实是普遍存在的。图书采购工作是整个图书馆工作的基础和起点,采购图书质量直接决定了馆藏质量,也决定着图书馆的服务水平。传统的图书采购存在效率低、主观性过强、科学性不强等种种问题,图书馆管理人员希望能够从日常服务数据中找出为图书采购提供决策支持的信息,以解决此类问题,图书采购系统也由此产生。而恰恰由于图书采购系统同样也有不完全信息,因此我们将图书采购系统当作灰色系统来处理,研究其灰色性,并依据灰色系统理论,建立图书采购灰色系统模型。为了更好的满足读者需求,提升图书采购工作效率及质量,本文首先阐述了灰色系统理论的基本概念及原理;其次,介绍了系统建模的相关原理及途径方法,并对灰色系统建模基础加以介绍;再次,从图书采购的概念、流程等方面对图书采购工作进行描述,并对图书采购系统的灰色性及灰色系统建模在图书采购系统中的运用可行性进行分析;最后,利用五步建模思想建立基于灰色系统理论的图书采购系统决策模型。
[Abstract]:Grey system theory is a new subject put forward by Professor Deng Julong in 1982. It aims to study the uncertain system of "part of information is known, part of information is unknown". Is through the "partial" known information generation, the development, realizes to the real world exact description and the understanding. The so-called gray system, general refers to the information incomplete system. Objectively speaking. The world that people realize is composed of "grey system". Because of the universal connection of all things, the system exists universally with people's life; Because of the limitation of people's cognition, people are used to ignore the unknown factors which will affect the result when dealing with practical problems. Thus, people treat grey system as white system. Therefore, grey system is universal. Book procurement is the basis and starting point of the whole library work. The quality of purchasing books directly determines the quality of library collection and the service level of library. Traditional book procurement has many problems such as low efficiency, too subjective, not scientific and so on. Library managers hope to find information from the daily service data to provide decision support for book procurement in order to solve such problems. The book procurement system is also produced. And precisely because the book procurement system also has incomplete information, so we treat the book procurement system as a grey system to study its grey nature. According to the theory of grey system, the paper establishes the grey system model of book procurement, in order to better meet the needs of readers, improve the efficiency and quality of book procurement. In this paper, the basic concept and principle of grey system theory are introduced. Secondly, the related principles and methods of system modeling are introduced, and the foundation of grey system modeling is introduced. Thirdly, the paper describes the work of book procurement from the aspects of the concept and flow of book procurement, and analyzes the grey nature of the book procurement system and the feasibility of the application of the grey system modeling in the book procurement system. Finally, a decision model of book purchasing system based on grey system theory is established by using five-step modeling idea.
