基于Mediator/Wrapper的VMI系统的研究

Research on VMI System Based on Mediator/Wrapper

供应商管理库存(VMI)是一种新的供应链库存管理方法,通过应用VMI,可以提高企业的运作水平,降低供应商和生产商、零售商的成本。然而,在电子商务环境下,供应商与生产商或零售商是多对多的关系,VMI系统的数据间的通信变得十分庞大复杂,信息的管理也变得很困难。为此,本文提出使用Java和XML开发基于Mediator/Wrapper的VMI系统,通过Mediator构建一个以客户应用层、中介器层和数据源层三层VMI系统,使用XML作为中介器层的数据的标准以及客户应用层和中介器层的接口,并提供统一的描述数据的结构的框架,以便在Web上部署,同时Wrapper可以解决多个供应商和零售商之间的信息异构问题。

Vendor managed inventory（VMI）is a new idea of inventory management.Through application of VMI,enterprises can effectively improve the operation level and reduce the cost of supplier,manufacturer and retailer.Under E-business environment,however,supplier,manufacturer and retailer are more-to-more relationship,data communication of VMI System becomes complex,and difficult to manage information.According to this,Java and XML having been used to develop Mediator/Wrapper-based VMI System are proposed.By using Mediator,the three layers of VMI System are constructed,which consist of client application layer,mediation layer and data resources layer.XML has been chosen to develop and to standardize the data model at the mediator tier,and the interface between client application and the mediators.This makes it easier to deploy on Web.Wrapper can resolve the problem of heterogeneous information between supplier and retailer.
