在環境變動日益劇烈的現今，市場上的競爭已從單純的企業與企業間提昇到供應鏈與供應鏈之間的競爭，因此供應鍊成員的協同合作將是非常重要的課題。隨著資訊科技及網際網路的發展，企業可以打破供應鏈成員之間的籓籬而形成延展示供應鍊. i-Hub及其驅動的供應鏈集中規劃將成為此環境下，供應鏈成員間協同合作的新平台。本研究即在探討於此i-Hub及其供應鏈集中規劃對企業營運之影響。
本研究首先對延展式供應鏈，協同合作，虛擬企業及跨組織關係等相關議題做探討，並對供應鏈與延展式供應鏈做本體論分析，以釐清其組成個體之間的關係。
再以i-Hub由其內部之功能: “collaborative master planning”, “collaborative master planning”, “control/alert system” 及 “data warehouse & learning system”所驅動之集中規劃為基礎來探討其對企業內部規劃及供應鏈成員間關係所受到之影響。
本研究以協同合作模式來描述供應鏈成員間及與i-Hub之互動，分別使用 “主持i-Hub的角色” 及 “選擇供應鍊成員的方式”做為區分協同合作模式的構面。在對企業內部規劃的影響方面，對中期的demand planning 及 master planning是以抽離為主，對短期且偏執行層面的規劃活動則受到i-Hub的即時監控。本研究為以
延展式供應鏈及i-Hub為背景之研究提供了一根本概念發展之基礎。

In order to gain the sustained competitive advantage in this more and more dynamic business environment, collaboration between supply chain members is critical to success. With the development of internet, the business boundaries between supply chain members could be broken and form the extended supply chain. i-Hub, the driver of centralized planning scenario, will be critical mechanism to enable the new collaboration environment. And how do i-Hub and its centralized planning function influence business is our focus.
In this thesis, we first review the relative literatures about extended supply chain, collaboration, virtual enterprise and inter-organizational relationships. Next, we propose the supply chain and extended supply chain ontology to clarify the relationships among entities in the supply chain network. After that, the infrastructure of i-Hub is identified. Based on these fundamental concept developments, we can dig into the influence of i-Hub to business. We take two perspectives to check these influence made by i-Hub. First is the influence happening among supply chain members, we propose the “collaboration mode” to identify these relationships driven by i-Hub. Second, the influence happening within business planning activities, we divide the internal planning activities into several modules and find that there are two influences, “extraction” and “control/monitor”, to different planning activities respectively.
This research could be the fundamental basis for researches which take the i-Hub, centralized planning, and extended supply chain as assumption and environment. And this thesis also sketches the contours of various further research topics.
