【摘要】：云服務(wù)供應(yīng)鏈的供需匹配是指在給定的供給或者需求策略下,通過合適的契約管控供應(yīng)鏈,實現(xiàn)系統(tǒng)的服務(wù)水平和利潤的最優(yōu)化,締造一個精益供應(yīng)鏈。本文主要的研究工作和成果:(1)提出了符合云服務(wù)收費特點的兩部收費制契約。本文在動態(tài)定價機制思想的指導(dǎo)下,結(jié)合SLA協(xié)議的內(nèi)容,提出了符合云服務(wù)特點的供應(yīng)鏈利潤表達函數(shù),并通過改變供應(yīng)鏈的付費結(jié)構(gòu)-兩部收費制契約實現(xiàn)了系統(tǒng)需求,價格,供給的同時最優(yōu)。(2)提出了雙向期權(quán)契約來協(xié)調(diào)具有預(yù)訂和能力擴展柔性的云服務(wù)供應(yīng)鏈。本文在考慮能力易逝性,遷移成本,服務(wù)可得性等云服務(wù)特點的基礎(chǔ)上,提出了兩種能力供給策略,并證明了由于高昂的服務(wù)延遲成本和資源搭建成本,預(yù)訂和能力擴展相結(jié)合的供給策略優(yōu)于隨需而配的策略,此外還運用了雙向期權(quán)契約實現(xiàn)了預(yù)訂場景下的供應(yīng)鏈的協(xié)調(diào)。(3)設(shè)計了有區(qū)分度的兩部收費制契約實現(xiàn)了私有需求信息的揭示。本文假設(shè)了供應(yīng)鏈成員具有單方私有信息的場景,并通過兩部收費制契約,揭示了真實的需求信息,改進了供應(yīng)鏈的利潤。
[Abstract]:The supply and demand matching of cloud service supply chain is to realize the optimization of the service level and profit of the system under the given supply or demand strategy, and to create a lean supply chain. The main research work and achievements of this paper are as follows: (1) A two-part contract of charging system is proposed, which accords with the characteristics of cloud service charges. Under the guidance of dynamic pricing mechanism and the content of SLA protocol, this paper puts forward the profit expression function of supply chain in accordance with the characteristics of cloud service, and realizes the system demand by changing the payment structure of supply chain-two charge system contracts. (2) A bi-directional option contract is proposed to coordinate the cloud service supply chain with reservation and capacity expansion flexibility. On the basis of considering the characteristics of cloud services, such as capability perishable, migration cost and service availability, this paper proposes two capacity supply strategies, and proves that the high cost of service delay and the cost of building resources. The supply strategy combined with reservation and capacity expansion is superior to the on-demand strategy. In addition, a bi-directional option contract is used to coordinate the supply chain under the reservation scenario. (3) A two-part fee system contract with differentiated degree is designed to reveal the private demand information. This paper assumes that supply chain members have unilateral private information, and reveals the real demand information through two charging contracts, which improves the profit of the supply chain.
