【摘要】：称重系统作为企业ERP数据源获取的一个重要组成部分,在企业物资管理及物流信息化中具有举足轻重的作用。目前,称重系统智能化在设计与实施中还存在以下问题:不能适应不同的软硬件环境;界面布局过于固定;计算公式单一且难以更改等。本文从系统本身使用角度出发,提出一种面向柔性需求的智能称重系统,以此来解决称重系统适应多元化环境的问题。本文在查阅了大量国内外优秀文献的基础上,引入软系统方法论的基本思想,按照柔性需求分析、算法设计、系统实施、实例分析与效果评价这一技术路线,在智能称重系统的公式求解和界面柔性布局上做了一定的研究,主要体现在以下几个方面:第一,以软系统方法论为基础,采用富图分析法描述问题情境,进行有关系统根定义并建立S(C,Aj,Pj,W,O,E)柔性需求模型,设计面向柔性需求的智能称重系统的体系结构和功能模块。第二,对系统实现的关键技术进行了探讨,主要包括基于中缀表达式的递归拆分公式求解算法、基于可变分辨率的界面布局算法和基于U-RAM三维矩阵模型的多角色权限/模块数据表结构设计。第三,分别从公式的自定义编辑、界面控件的自适应性布局和多角色权限设置三个方面给出了具体的系统运行实例,最后对系统实施的效果进行了评价。
[Abstract]:As an important part of enterprise ERP data acquisition, weighing system plays an important role in enterprise material management and logistics informatization. At present, the intelligent weighing system still has the following problems in the design and implementation: can not adapt to different software and hardware environment, interface layout is too fixed, calculation formula is single and difficult to change, etc. In this paper, from the point of view of the system itself, an intelligent weighing system for flexible requirements is proposed to solve the problem that the weighing system adapts to the diversified environment. On the basis of consulting a large number of excellent literatures at home and abroad, this paper introduces the basic idea of soft system methodology, according to the technical route of flexible demand analysis, algorithm design, system implementation, case analysis and effect evaluation. In this paper, the formula solution of intelligent weighing system and the flexible layout of interface are studied, which are mainly reflected in the following aspects: firstly, based on the soft system methodology, the problem situation is described by using rich graph analysis method. The definition of system root and the establishment of S (C _ J _ (J) PJ _ (J) WO _ (E) flexible requirement model are carried out, and the architecture and function module of intelligent weighing system for flexible requirement are designed. Secondly, the key technologies of the system are discussed, including the recursive split formula solving algorithm based on the infix expression. Interface layout algorithm based on variable resolution and multi-role authority / module data table structure design based on U-RAM 3D matrix model. Thirdly, the system running examples are given from three aspects: the custom editing of the formula, the adaptive layout of the interface control and the multi-role permission setting. Finally, the effect of the system implementation is evaluated.
