【摘要】：云計(jì)算通過Internet將一切計(jì)算資源以服務(wù)的形式提供給用戶,而根據(jù)不同的資源類型和服務(wù)層次,可以將資源提供者劃分為IaaS、 PaaS、SaaS服務(wù)提供商。針對(duì)這一背景,本文以云計(jì)算服務(wù)提供商為主體,構(gòu)建云計(jì)算服務(wù)供應(yīng)鏈。以減少需求不確定性所帶來(lái)的風(fēng)險(xiǎn)和提高云計(jì)算服務(wù)供應(yīng)鏈績(jī)效為目標(biāo),設(shè)計(jì)出行之有效的、并為各方主體所樂于接受的協(xié)調(diào)機(jī)制。 本文的研究主要集中在以下三個(gè)方面： (1)設(shè)計(jì)了一種聯(lián)合契約,即引入獎(jiǎng)勵(lì)與懲罰機(jī)制的數(shù)量柔性契約,實(shí)現(xiàn)了對(duì)稱信息下二級(jí)云計(jì)算服務(wù)供應(yīng)鏈的協(xié)調(diào)。該服務(wù)供應(yīng)鏈由AIP(Application Infrastructrue Provider)和ASP(Application Service Provider)構(gòu)成,其中ASP向AIP租賃計(jì)算能力服務(wù),并將增值的服務(wù)提供給市場(chǎng)。假設(shè)在完全信息市場(chǎng)中,市場(chǎng)需求服從均勻分布且價(jià)格敏感。以LF博弈(Leader-follower Game)理論考察AIP與ASP的決策行為。通過對(duì)比集中決策、分散決策、數(shù)量柔性契約和聯(lián)合契約下,供應(yīng)鏈的整體績(jī)效,說(shuō)明聯(lián)合不僅能實(shí)現(xiàn)供應(yīng)鏈協(xié)調(diào),還能任意分配協(xié)調(diào)利潤(rùn)。 (2)提出了一種數(shù)量折扣和收入共享的聯(lián)合契約,實(shí)現(xiàn)了不對(duì)稱信息下二級(jí)云計(jì)算服務(wù)供應(yīng)鏈網(wǎng)絡(luò)的協(xié)調(diào)。該網(wǎng)絡(luò)由1個(gè)AIP、1個(gè)潛在AIP和N個(gè)ASP構(gòu)成,其中AIP與潛在AIP競(jìng)爭(zhēng)為ASP提供服務(wù)；不同的ASP面向市場(chǎng)提供不同類型的SaaS服務(wù),該服務(wù)系統(tǒng)可近似抽象為M/M/1排隊(duì)系統(tǒng)。ASP面對(duì)相互獨(dú)立、價(jià)格敏感的等彈性需求。ASP擁有私有信息,即市場(chǎng)需求和自身最小服務(wù)期望租賃量。研究結(jié)果表明,分散決策及數(shù)量折扣契約無(wú)法實(shí)現(xiàn)供應(yīng)鏈協(xié)調(diào),而聯(lián)合契約不僅能實(shí)現(xiàn)供應(yīng)鏈的績(jī)效協(xié)調(diào),還能提供參與方的利潤(rùn)。 (3)運(yùn)用數(shù)量折扣與聯(lián)合契約的聯(lián)合應(yīng)用,實(shí)現(xiàn)了不對(duì)稱信息下的三級(jí)云計(jì)算服務(wù)供應(yīng)鏈網(wǎng)絡(luò)的協(xié)調(diào)。該網(wǎng)絡(luò)由1個(gè)AIP、1個(gè)APP(Application Platform Provider)和N個(gè)ASP構(gòu)成。AIP為APP提供計(jì)算能力服務(wù),APP為ASP提供平臺(tái)服務(wù),ASP向市場(chǎng)提供增值的應(yīng)用服務(wù)。ASP面對(duì)相互獨(dú)立、價(jià)格敏感的等彈性需求,且擁有私有信息。研究表明,參與各方的自利行為將導(dǎo)致雙邊際化效應(yīng),而聯(lián)合契約能有效的引導(dǎo)和激勵(lì)各方的決策行為,實(shí)現(xiàn)供應(yīng)鏈的協(xié)調(diào)。
[Abstract]:Cloud computing provides all computing resources to users in the form of services through Internet. According to different resource types and service levels, resource providers can be divided into IaaSs, PaaSnSaaS service providers.In view of this background, this paper takes cloud computing service provider as the main body, constructs cloud computing service supply chain.Aiming at reducing the risk of demand uncertainty and improving the performance of cloud computing service supply chain, an effective and acceptable coordination mechanism is designed.This paper focuses on the following three aspects:1) A joint contract is designed, that is, the quantity flexible contract with reward and punishment mechanism is introduced to realize the coordination of the two-level cloud computing service supply chain under symmetric information.The service supply chain consists of AIP(Application Infrastructrue provider and ASP(Application Service provider, where ASP rents computing power to AIP and provides value-added services to the market.Assume that in a complete information market, market demand is evenly distributed and price-sensitive.The decision behavior of AIP and ASP is investigated by using the Leader-follower game theory of LF game.By comparing the overall performance of supply chain with centralized decision, decentralized decision, quantity flexible contract and joint contract, it is shown that alliance can not only realize coordination of supply chain, but also distribute coordination profit arbitrarily.A joint contract of quantity discount and revenue sharing is proposed to coordinate the two-level cloud computing service supply chain network under asymmetric information.The network consists of an AIP, a potential AIP and N ASP, in which AIP competes with potential AIP to provide services for ASP, and different ASP provide different types of SaaS services to the market. The service system can be abstracted as M/M/1 queuing system.The price-sensitive iso-elastic demand .ASP has private information, that is, the market demand and its own minimum service expected lease amount.The results show that decentralized decision and quantity discount contract can not achieve supply chain coordination, and the joint contract can not only achieve the coordination of supply chain performance, but also provide the profits of the participants.3) the coordination of three-level cloud computing service supply chain network under asymmetric information is realized by using the combined application of quantity discount and joint contract.The network is composed of 1 AIP, 1 APP(Application Platform provider, and N ASP. AIP provides computing power service for APP. App provides platform service for ASP. ASP provides value-added application service. ASP is faced with independent, price-sensitive and other elastic demands, and has private information.The research shows that the self-interest behavior of the parties involved will lead to the double marginalization effect, and the joint contract can effectively guide and motivate the decision-making behavior of the parties and achieve the coordination of the supply chain.
