【摘要】 随着信息技术的不断发展，中小型制造企业信息化建设越来越重要。为了适应当前信息社会激烈的市场竞争，中小型企业要提高自己的经济效益必须要进行业务流程重组，充分利用企业已有资源来增强企业经营活力。从MRP到MRPⅡ，再到ERP，企业信息管理系统覆盖的范围在不断地深入和扩大，中小型制造企业通过成功实施先进的企业资源计划系统必然能提高企业自身的竞争力。同时，许多中小型制造企业采用的都是基于订单生产的模式，强调以销定产。那么，如何有效地解决基于订单生产的中小型制造企业资源计划系统问题，把客户订购的信息有效地导入生产企业的ERP系统并及时地生产出客户需求的产品显得尤其重要。本课题针对这一主题展开研究，并在基于订单生产的中小型制造企业加以实践研究，同时对基于订单生产模式的中小型制造企业ERP模型进行了研究。 论文首先分别介绍了Intranet、数据库技术的发展及其应用，同时对信息系统建模方法和制造业生产类型开展了研究；特别阐述了基于订单生产的中小型制造企业ERP研究的核心问题，强调以订单驱动模式为核心，建立面向订单的参数化物料清单。在相关研究基础上，本课题以浙江巨人电梯有限公司企业资源计划系统为应用实例，对该企业基于订单生产的中小型制造企业资源计划系统GEERP作了应用研究和具体实践，对实施这一系统的关键技术作了详尽的探讨，具体在以下几个方面：（1）数据库技术；（2）基于UML的Web应用系统的建模技术；（3）B/S模式和C/S模式相结合的信息系统开发技术。 之后，论文对GEERP系统的实现进行了探讨，分别详细阐述了在硕士阶段研究的ERP两大子系统：销售合同管理系统和生产管理系统的实现；在对所做的研究和实践工作总结的基础上，对基于订单生产的中小型制造企业ERP模型开展了研究，用I₂DEF建模方法建立了系统的结构模型、动态模型和功能模型，最后论文提出了进一步研究的方向。更多还原

【Abstract】 With the development of information technology, informatization of small medium manufacturing enterprises becomes more and more important. In order to adapt to the current intensive market competition, enterprises need enhance their economic effect. Therefore, they should reprocess their business logic and then make full of their resources available. From MRP to MRPn, then to ERP, the range involved by enterprise management information systems has been deepen and expanded more greatly. And small medium manufacturing enterprises will boost their competitive ability by successfully putting the Enterprise Resource Planning system in practice. At the same time, currently, many enterprises’ activities are based on the mode of Make to Order. They emphasize on the need of customers. So it’s important for us to effectly solve the Enterprise Resource Planning of Make to Order based small medium manufacturing enterprises. In other words, we should effectly put the customer’s order information into the ERP system and then the enterprises quickly make the specific products that customers have required. This thesis is involved in research on application and modeling of Make to Order based small medium manufacturing enterprises ERP system.At the beginning of this thesis, it introduces the development and application of Intranet and database technology respectively. Also research on the modeling methods of information systems is carried out. At the same time, the manufacturing types and development of the ERP system are introduced. Then, the thesis deals with issues of Make to Order based small medium manufacturing enterprises ERP system. The thesis emphasizes the importance of orders and conduct research on the order parametrized Bill of Material. After that, Zhejiang Giant-Elevator Limited Corporation is taken for an example and the thesis puts Make to Order based small medium manufacturing enterprises ERP system GEERP into practice. Also, the thesis discusses the key technology used in the implemention of this system, which is involved in the following aspects: 1) database technology; 2) UML base web modeling technology; 3) information development technology combining B/S with C/S pattens. After all of the work, the implementation of the GEERP system is expatiated on, especially of two critical subsystems of sales and production management information systems.Based on research and practice of Make to Order based small medium manufacturing enterprises ERP, this thesis conducts reseach on system modeling of Make to Order based small medium manufacturing enterprises ERP and builds the structure model, dynamic model and function model of the system using L;DEF modeling method. In the end of this thesis, conclusions and prospects are given in the end of this thesis.更多还原
