退貨産品在國民經濟中發揮重要作用,近些年來在工業界和學術界引起廣泛關注。由于受到退貨産品的巨大經濟潛能驅動以及迫于相關法律的強大壓力,企業開始積極整合現有供應鏈流程和産品退貨流程,但是在這個過程中生産計劃和庫存管理運營遇到了前所未有的挑戰。本論文分析了可修護單壹産品的多周期庫存系統管理問題,其中該庫存系統包含隨機的新産品需求和産品保修需求。所探討的系統還包含了以下特征: i. 産品供應源的完美替換。新訂購産品和維修後的退貨産品並無二異。ii. 需求優先級。在單個周期內,新産品需求優先級高于保修需求。iii. 新産品訂購和退貨産品維修特性。兩項流程交付時間都假設爲零。在每個周期中,維修退貨産品過程涉及且考慮維修損失。我們探尋到了所考察系統的最優庫存補貨和處理控制策略。 ; Product returns play an important role in the economy and have attracted more and more attention both from industry and academia in the past few years. Motivated by enormous economic potential of and dramatic legislation pressure on product returns, companies today actively integrate product-return processes with their existing forward supply-chain processes, but must confront the considerable challenge of production planning and inventory control problems compared to traditional problems without returns and repairs. ; This thesis analyzes a multi-period single-item repairable inventory system with stochastic new and warranty demands. The system investigated has the following features: i. perfect substitution of supply sources. Newly-procured items are indistinguishable from items repaired from repairable warranty returns. ii. demand priority. New demand has higher priority than warranty demand within a period and thus needs to be satisfied first. iii. properties on the processes of purchasing and repairing. We assume zero lead-time for both processes. Further we capture the "repair loss" in repairing returns in each period. We identify the optimal inventory replenishment and disposal policies for the investigated system. ; Detailed summary in vernacular field only. ; Lin, Yizhong. ; Thesis (Ph.D.) Chinese University of Hong Kong, 2014. ; Includes bibliographical references (leaves 80-87). ; Abstracts also in Chinese.
Despite the differences in our cultural, economic, and political systems China and Australia are societies sharing rapidly urbanising futures. This presents significant challenges for urban planning, placemaking, and the sustainability of livable, urban communities. Using Chongqing as a case study, metaPLACE is an experimental project investigating how participatory urban media (large and small interactive screens, installations, façades, and devices) can act as a co-designed interface between diverse community, industry, and government stakeholders. The empirical data gathered from a co-design workshop held in Chongqing in 2019 indicates there are a range of opportunities and concerns related to equitable placemaking, the environment, the nature of interfaces and participation, ownership and management of data, large and small screens, and cultural and generational considerations. Our critical and comparative analysis of the research design and cultural factors influencing the co-design process, reveal deficiencies in widely accepted models of user experience design and design process used across industry and design research. This has significant implications for transcultural and interdisciplinary co-design and the establishment of a viable Sino-Australian design ecosystem.
這項研究探討信息科技在中國的技術政治。研究試圖書寫電子計算機作為一種新的電子信息科技在中國早期設置過程的技術政治社會史,並在理論層面上尝试构建一個拓展了的「技術、社會、與勞動」的進路。源於冷戰的地緣政治結構,不像韓國、台灣、或香港等其他亞洲國家和地區 ,在1980年代改革開放以前,中國大陸的計算機工業已經經歷了近30年(1955-1984)連續且激進的獨立發展。特別需要指出的是,中國社會主義時代的計算機發展不僅僅是爲了滿足冷戰中的國防需要和技術民族主義意識形態下社會動員的需要,同時高度嵌入了有關階級政治和技術哲學的社會主義「社會實驗」當中。而隨著文革群眾運動的終結和中國的「改革開放」,鄧小平為首的國家決策層爲了回應來自外部的壓力和來自社會主義內部的危機,用實用主義的技術發展觀取代了社會主義的技術民主實踐。1984年,隨著阿尔文.托夫勒(Alvin Toffler)的《第三次浪潮》(The Third Wave)風靡中國大陸,革命中國的計算機工業和技術政策逐步被隨新自由主義全球化而來的「信息社會」和「矽谷模式」所取代。 ; 作為一個技術和文化的雙重物件,電子計算機及其衍生科技(臺式計算機、筆記本電腦、智慧手機、平板電腦等)是理解當代資本主義生產、消費、與勞動關係的指標性科技。然而在社會主義中國的革命現代化進程中,它卻曾經一度拐入了一條另類的發展路徑。中國的信息化(informationalization)或曰計算機化(computerization)過程中的技術路線鬥爭和轉型是如何發生的,這一進程與中國「從毛到鄧」的獨特現代化道路之間是怎樣的關係?時至今日,批判的傳播研究對這段歷史依然所知甚少。本文試圖重訪這個歷史轉折,探查計算機在中國的早期技術政治史。通過追蹤關鍵的歷史事件、人物、思潮、和政策,論文試圖探尋冷戰架構下東西方技術政治之間的交鋒,如何在被計算機仲介的生產與勞動關係中顯影。從這個「閃回」中得到的知識,有助我們將對今日中國信息產業和信息勞動的理解,重新納入中國革命現代性的潮起潮落之中。 ; This paper traces the political and social history for the installation process of digital technology in China, in order to shed light on the ways in which computer interacted with the transformation of Chinese socialism. Due to geopolitical structure of the Cold War, unlike other East Asian countries, before 1980s China had developed its independent computer industry for more than 30 years. This development was not just under the rubric of techno-nationalism, which mainly helps to fulfill military and national defense aims, but also embedded into proletariat political debates. Maoist China developed a dialectical approach to technology, in which the most powerful productive power is the revolutionary proletariat class per se, not the machine or technology. So the process of socialist technology development, like the process of socialist culture and arts development is also a dialectical process, which must follow mass line to not just develop productive force, but also transform production relations and create socialist subjectivity. Instead, the post-Mao leadership under Deng Xiaoping responded to external Cold War pressures and the profound internal crises of ...
