以中介者為基礎之彈性化電子商務架構

Abstract

網際網路購物的交易過程中，可以使用各種不同的交易協定或交易方 式，而每種方式中，資訊傳遞的流程、傳遞資訊的內容以及交易處理流程 也都不盡相同，如果要替每一種交易協定設計出相對的應用程式，不但要 花費許多人力進行設計實作，消費者也必須熟悉不同的廠商所提供的交易 介面。所以發展出一個各種不同的交易協定都能共用的交易模式，讓消費 者只需熟悉使用一個交易環境即可使用各種交易協定是一個相當重要的研 究課題。此外，經由中介者進行網路購物可減少消費者購物之風險，也可 以提供產品搜尋、比較、訂購，付款以及售後服務等功能，這也是網路購 物交易實用化的重要考量。 本研究首先分析探討網際網路購物環境 下，各種交易協定、中介者角色以及彈性化購物模式，進而建構一個結合 基本交易功能及彈性處理交易流程，以滿足不同商務協定的彈性商務模式 。我們所提出的模式是架構在提供各種付款、產品搜尋以及送貨機制等功 能的服務系統上。隨著與中介者的整合，我們的模式可以涵蓋交易前期、 交易期以及交易後期的商務交易協定。最後，本研究建構了一個以中介者 為基礎之彈性化電子商務模式之雛形系統。 In Internet shopping, there are many different commerce protocols to process transactions between customers, merchants, and intermediaries. Each protocol handles different messages and different flow of transactions. A lot of work will be needed to implement various commerce protocols. Besides, customers need to be familiar with various shopping mechanisms supported by different merchants, and consequently, it is not convenient for customers to conduct Internet shopping. Therefore, it is a key issue to develop a unified Internet commerce model that can adapt various commerce protocols enabling customers to use various shopping mechanisms conveniently. Moreover, shopping through intermediary can reduce the shopping risks for customers. Integrating the intermediary with Internet shopping mechanism to support various services including search, compare, order, payment and after-sale services is important for realizing Internet shopping. In this work, we analyze various commerce protocols and the roles of intermediary in order to develop an intermediary-based flexible commerce model. Our primary goal is to design a flexible Internet commerce model that integrates primitive transaction functions and flexible processing of transaction flow to adapt to various commerce protocols. The proposed model is built on top of the service systems that provide various payment, search and delivery mechanisms. With the intermediary, various commerce protocols covering pre-trade, trade and post-trade phases can be supported. Finally a prototype system is developed to demonstrate our work on intermediary-based flexible commerce model.
