【摘要】：在傳統(tǒng)的采購流程中企業(yè)需要投入巨大的人力和時(shí)間，往往還無法做到采購的實(shí)時(shí)化透明化。電子采購系統(tǒng)的出現(xiàn)就是要解決這些問題，使公司各級(jí)采購監(jiān)管部門能夠及時(shí)全面地查詢、統(tǒng)計(jì)、分析、評(píng)價(jià)其管轄范圍內(nèi)的采購合同/訂單執(zhí)行情況、采購質(zhì)量情況和采購成本情況等，從而為公司內(nèi)實(shí)現(xiàn)供應(yīng)鏈級(jí)產(chǎn)品協(xié)同研發(fā)打下基礎(chǔ)，降低產(chǎn)品研發(fā)成本，加快產(chǎn)品研發(fā)與商品化的速度。 此次的電子采購系統(tǒng)的特點(diǎn)在于采用B/S結(jié)構(gòu)相較于C/S結(jié)構(gòu)它可以在任何地方進(jìn)行操作，只要電腦能上網(wǎng)并安裝有Internet Explorer9.0以上版本的瀏覽器便可以隨時(shí)隨地進(jìn)行采購管理。而此次的系統(tǒng)基于MVC（Model View Controller一種軟件設(shè)計(jì)模式）模式不但有利于開發(fā)過程中編程人員的分工，更因?yàn)镸VC模式中，三層的松耦合性質(zhì)使得當(dāng)業(yè)務(wù)需求發(fā)生改變時(shí)，可以減少修改的工作量，有益于系統(tǒng)的后期修改和維護(hù)工作。系統(tǒng)的前臺(tái)實(shí)現(xiàn)采用了JSF框架，，數(shù)據(jù)庫采用的SQL Server2008。 軟件開發(fā)過程一般包括需求分析、系統(tǒng)設(shè)計(jì)、編碼和測試四個(gè)階段。由于文章篇幅有限，所以僅以電子采購平臺(tái)中的請(qǐng)購功能模塊和采購管理模塊為例，主要從需求分析、系統(tǒng)設(shè)計(jì)、編碼和測試四個(gè)方面詳細(xì)介紹了請(qǐng)購管理和采購管理模塊的實(shí)現(xiàn)。 本文首先整理了整個(gè)電子采購系統(tǒng)的所有主要業(yè)務(wù)需求，共分成了十一個(gè)功能模塊，針對(duì)請(qǐng)購管理和采購管理的功能模塊進(jìn)行需求分析，隨后我們分析了系統(tǒng)的用例圖，并從請(qǐng)購現(xiàn)狀查詢，請(qǐng)購單制作，查詢以及導(dǎo)出四個(gè)功能分析了他們所需的相關(guān)數(shù)據(jù)項(xiàng)。由于系統(tǒng)是三層構(gòu)架，所以我們分別從數(shù)據(jù)服務(wù)層，業(yè)務(wù)邏輯層以及表現(xiàn)層三個(gè)方面介紹了請(qǐng)購系統(tǒng)的設(shè)計(jì)與編碼實(shí)現(xiàn)。完成請(qǐng)購和采購系統(tǒng)的編碼后，按照之前業(yè)務(wù)需求的要求，對(duì)此電子采購系統(tǒng)的登錄界面、請(qǐng)購管理和采購管理功能進(jìn)行單元功能測試。文章的最后對(duì)此次非生產(chǎn)性電子采購的開發(fā)過程進(jìn)行了總結(jié)并對(duì)電子采購的未來發(fā)展提出了展望。 論文中介紹的采購系統(tǒng)已基本實(shí)現(xiàn)功能，電子采購平臺(tái)將實(shí)現(xiàn)與公司財(cái)務(wù)或其他系統(tǒng)業(yè)務(wù)的數(shù)據(jù)集成，實(shí)現(xiàn)與研發(fā)或生產(chǎn)等其他業(yè)務(wù)部門在業(yè)務(wù)、信息方面的高效互動(dòng)。
[Abstract]:The emergence of electronic procurement system is to solve these problems, so that the procurement supervision departments at all levels of the company can timely and comprehensive inquiry, statistics, analysis, evaluation of the purchasing contract / order within their jurisdiction. Conditions, procurement quality and procurement costs, so as to lay the foundation for the realization of supply chain-level product collaborative R&D within the company, reduce product R&D costs, speed up product R&D and commercialization.
The E-procurement system is characterized by B/S structure compared to C/S structure, it can operate anywhere, as long as the computer can access the Internet and install Internet Explorer version 9.0 browser can be purchasing management anytime and anywhere. This system is based on MVC (Model View Controller a software design model). The mode is not only beneficial to the division of labor of programmers in the development process, but also because the loosely coupled nature of the three layers in the MVC mode can reduce the workload of modification when the business requirements change, which is beneficial to the later modification and maintenance of the system.
The software development process generally includes four stages: requirement analysis, system design, coding and testing. Because of the limited space of the article, this paper only takes the requisition function module and purchasing management module in the electronic purchasing platform as an example, and introduces the requisition management and purchasing management in detail from four aspects: requirement analysis, system design, coding and testing. Block implementation.
Firstly, this paper sorts out all the main business requirements of the whole E-procurement system, and divides it into eleven functional modules. Then we analyze the requirement of the function modules of requisition management and purchasing management. Then we analyze the use case diagram of the system and analyze it from four functions: requisition status inquiry, requisition order making, inquiry and export. Since the system is a three-tier architecture, we introduce the design and coding of the requisition system from three aspects: data service layer, business logic layer and presentation layer. The function of purchasing management and purchasing management is tested. Finally, the paper summarizes the development process of this non-productive e-procurement and puts forward the prospect of the future development of e-procurement.
The purchasing system introduced in this paper has basically realized its functions. The electronic purchasing platform will realize the data integration with the company's financial or other system business, and realize the efficient interaction with other business departments such as R&D or production in business and information.
