Design and pricing of maintenance service contract based on Nash non-cooperative game approach

Nowadays manufacturers are facing fierce challenge.Apart from the products,providing customers with multiple maintenance options in the service contract becomes more popular,since it can help to improve customer satisfaction,and ultimately promote sales and maximize profit for the manufacturer.By considering the combinations of corrective maintenance and preventive maintenance,totally three types of maintenance service contracts are designed.Moreover,attractive incentive and penalty mechanisms are adopted in the contracts.On this basis,Nash non-cooperative game is applied to analyze the revenue for both the manufacturer and customers,and so as to optimize the pricing mechanism of maintenance service contract and achieve a win-win situation.Numerical experiments are conducted.The results show that by taking into account the incentive and penalty mechanisms,the revenue can be improved for both the customers and manufacturer.Moreover,with the increase of repair rate and improvement factor in the preventive maintenance,the revenue will increase gradually for both the parties.

Allocation of Public Service Facilities in Villages and Towns from the Perspective of Smart Contraction: A Case Study of Zixi County, Jiangxi Province

The limitation of traditional layout system and the continuous contraction of villages and towns have brought challenges to the layout of public service facilities.It is an imperative task against this background to integrate space resources and allocate public service facilities scientifically and reasonably.This paper took the system and method of rural public service facility allocation from the perspective of smart contraction as the theoretic support,and Zixi County in Jiangxi Province for example,built the four-level life circle of“county-fundamental-basic-routine”based on the influence factors of facility allocation,village and town contraction strength,rural comprehensive assessment results,residents’trip willingness and demands on public service facilities,finally proposed the suggestions for optimizing the allocation of village and town public service facilities.

Research on telecommunication resale service supply chain coordination with revenue-sharing contract

The competition and cooperation between traditional telecom operators and resale operators in the supply chain are discussed, when the telecom industry developed telecommunication resale service. Supply chain contract is an effective way to coordinate the supply chain. This paper analyzes the revenue-sharing contract between telecom operators and resale operators. The study shows that by setting up a rational revenue-sharing ratio and wholesale price, a revenue-sharing contract can coordinate this supply chain, and telecom operators and resale operators can achieve a 'win-win' solution.

Modeling optimal oil production paths under risk service contracts

Due to the rigorous fiscal terms and huge potential risk of risk service contracts,optimizing oil production paths is one of the main challenges in designing oilfield development plans.In this paper,an oil production path optimization model is developed to maximize economic benefits within constraints of technology factors and oil contracts.This analysis describes the effects of risk service contract terms on parameters of inputs and outputs and quantifies the relationships between production and production time,revenues,investment and costs.An oil service development and production project is illustrated in which the optimal production path under its own geological conditions and contract terms is calculated.The influences of oil price,service fees per barrel and operating costs on the optimal production have been examined by sensitivity analysis.The results show that the oil price has the largest impact on the optimal production,which is negatively related to oil price and positively related to service fees per barrel and operating costs.

Determination of Relationships and Al ocation of Responsibilities——Taking the Adjudication of Household Service Contract Disputes as an Example

The combination of the realistic demand of urban families to raise children and provide for the aged and the employment demand of rural migrant workers will inevitably lead to the continuous growth of the market demand for household care services.The determination of the tripartite legal relationship between household workers,household service agencies,and families(individuals)is an important issue for the normative development of the household service industry.In specific judicial practice,local courts perform differently in the determination of the relationship between“household workers and household service agencies.”The application of law in relevant cases also often swings between the civil law and the labor law.The Civil Code of the People’s Republic of China(hereinafter“the Civil Code”)does not retain the concept of“employment relationship”used in the original Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of Law in the Trial of Personal Injury Compensation Cases.Then,what is the relationship between household workers,household service agencies,and families(individuals)after the Civil Code came into force?This article shows the judicial dilemma currently faced by the household workers in the protection of labor rights and interests through an empirical analysis of the victim liability disputes of household workers and puts forward countermeasures and suggestions for improving the occupational injury protection mechanism of household workers in China through a comparative study of the occupational injury risk sharing mechanism of household workers and an analysis of the local exploration of the occupational injury protection system of flexible employees in China.

Contracts in the payments for ecosystem services: the case of bio-prospecting

We examine the economics of royalties in bioprospecting contracts between a pharmaceutical and genetic resource supplier （local）, with an eve to understanding the relative advantages of indexing royalty, payments to gross revenue or net revenue. We show a risk-averse firm facing only production or only cost risks will index royalties to net revenue. When facing both types of risk the choice of royalty type depends on the relative magnitudes of the production and cost risk. In each case, the risk-averse firm chooses the royalty-type that shifts as much risk as possible to the local. Wheat the local is risk neutral the pharmaceutical＇s and local＇s preferences are compatible.If the local is risk averse and there is only one type of risk, it will prefer a gross revenue royalty, and shift as much risk as possible to the firm： here the local and firm preferences are compatible only ifthe firm is risk-neutral. Lastly we show if the firm sets the terms of the contract and both agents are risk averse, the.firm will not likely volunteer to implement the socially optimal royalty arrangement as it prefers to shift as much risk to the loeal, who now also prefers a more certain return, This last outcome is at the heart of the benefit sharing discussionand suggests if risk sharing and equity are a concern in benefit sharing, then the choice of rcyalty type can be an important part of negotiations between pharmaceuticals and locals for the phytochemical from nature for new drug discovery.

Realty Service Contracts and the Legal System of Realty Management in China

The realty(real estate)management of ownership of buildings includes the owner(homeowner)entrust-management and the owner self-management,the former through the way of realty service contracts,the latter through the resolution of the owners’assembly and the owners’committee.The legal disputes of realty service contracts involve balancing interests among the realty service enterprise,individual owner,and all the owners.We should use dynamic balancing of the interests of the three parties to implement the interests of the win-win cooperation rather than the interests of the trade-off of“all or nothing.”The realty service contract is similar to the entrustment contract,both of which are based on the owners’entrustment.The duty to provide realty service is not simply equivalent to fiduciary duty.The realty service contract has the essence of both behavior debt and result debt.For the former,the general provisions of the entrustment contract can be referred to,and for the latter,the general provisions of the contract for work can be referred to.In view of the group characteristics of the realty service contract,owners have no right to terminate the realty service contract at any time but should obey the principle of due process and take the majority mechanism to make a dismissal resolution resolution.The resolutions and management stipulations worked out by the owners’assembly in a majority mechanism,both of which belong to resolution behavior and are legal tools of the owners’autonomy,shall be binding on all the owners.The relationship between the owner,the owner’s assembly,and the owner’s committee is similar to the fiduciary relationship.If the decision made by the owners’assembly or the owners’committee and the management stipulation infringes upon the legal rights and interests of the owners,the injured owner has the right to revocation litigation.At present,residential commodity owners have a relatively low degree of autonomy in China,and legal disputes over realty services are frequent.In the future,we need to perfect the legal incentive and constraint measures,and stimulate the vitality of owner autonomy to promote better implementation of the owner self-management and owner entrust-management.

Global trends and development of energy services industry in China

Energy service is an effective way to promote energy conservation by market mechanisms,including energy saving services,energy procurement,supply of many varieties of energy,supply of renewable energy technologies,energy-related consulting services,risk management,etc.China is a major energy consumer but energy is in short supply,and the efficiency of energy use is low.China's energy service industry has expanded rapidly,in terms of both the number of new Energy Service Companies entering the market and amount of capital invested in Energy Performance Contracting projects,but the energy service sector in China is still at an early stage of development.Developed countries began early in developing the energy service sector and their energy service market is mature,and the experience of developed countries shows that energy services play a significant role in advancing energy saving and emission reduction.Under the new situation,China needs combine energy services experience of developed countries,and take following measures to accelerate China's energy services rapid and healthy development,including the long-term aspects of policy planning,energy-saving core technology,finance and capital investment,public sector reductions,personnel training,and so on.

Privacy Protection Framework with Defined Policies for Service-Oriented Architecture

Service-Oriented Architecture (SOA) is a computer systems design concept which aims to achieve reusability and integration in a distributed environment through the use of autonomous, loosely coupled, interoperable abstractions known as services. In order to interoperate, communication between services is very important due to their autonomous nature. This communication provides services with their functional strengths, but also creates the opportunity for the loss of privacy. In this paper, a Privacy Protection Framework for Service-Oriented Architecture (PPFSOA) is described. In this framework, a Privacy Service (PS) is used in combination with privacy policies to create privacy contracts that outline what can and cannot be done with a consumer’s personally identifiable information (PII). The privacy policy consists of one-to-many privacy rules, with each rule created from a set of six privacy elements: collector, what, purpose, retention, recipient and trust. The PS acts as an intermediary between the service consumer and service provider, to establish an unbiased contract before the two parties begin sending PII. It is shown how many Privacy Services work together to form the privacy protection framework. An examination of what current approaches to protecting privacy in an SOA environment is also presented. Finally, the operations the PS must perform in order to fulfill its tasks are outlined.

Energy-Related Services as a Business:Eco-Transformation Logic to Support the Low-Carbon Transition

The transition to low-carbon development has been recognized as one of the most important directions for the transformation of national economies in most countries.Today we can identify two of the most common service-oriented logical models of this transition.These are models of Service-Dominant Logic and Product-Service Systems that are used in this study to create a service-oriented platformfor stimulating business development in the field of energy-related(ER)services.The establishment of such a platform is being considered based on the conceptual provisions of the global business ecosystem.Such a platform has been found to be a powerful tool for systemic coordinated cooperation between actors in the ER-services market and the relevant actors in the energy sector as well as in other industrial markets,unleashing the benefits of synergies,resulting from such cooperation.The logical models of attracting energy services companies to the creation of virtual communities(centers)for large-scale implementation of measures in the field of energy efficiency and renewable energy sources are presented in detail.The advantages of the practical implementation of logicalmodels are confirmed by calculations performed onmathematicalmodel adapted for engineering use in the field of ER-services.

Research on two-part revenue-sharing contract under demand disruption

Assuming that the realized demand is determined by the inventory level,a two-part revenue sharing contract of one supplier and one retailer is analyzed under the circumstance of demand disruption(the disruption cost occurs at the supplier).Based on the centralized optimization,the profits of the two members are maximized in sequential optimization though a two-part revenue-sharing contract.The result shows that when the demand disruption occurs,if the degree of disruption is within some range,the ordering and manufacturing plans need not be changed,while only the revenue sharing fraction for the retailer should be diminished;if not,both the plan and the revenue sharing fraction should be changed for the possible coordination of the supply chain.Finally,numerical illustrations of the contract for various scenarios are given.

Smart Contract Based DDoS Attack Traceability Audit Mechanism in Intelligent IoT

In this paper,we focus on providing data provenance auditing schemes for distributed denial of service(DDoS)defense in intelligent internet of things(IoT).To achieve effective DDoS defense,we introduce a two-layer collaborative blockchain framework to support data auditing.Specifically,using data scattered among intelligent IoT devices,switch gateways self-assemble a layer of blockchain in the local autonomous system(AS),and the main chain with controller participation can be aggregated by its associated layer of blocks once a cycle,to obtain a global security model.To optimize the processing delay of the security model,we propose a process of data pre-validation with the goal of ensuring data consistency while satisfying overhead requirements.Since the flood of identity spoofing packets,it is difficult to solve the identity consistency of data with traditional detection methods,and accountability cannot be pursued afterwards.Thus,we proposed a Packet Traceback Telemetry(PTT)scheme,based on in-band telemetry,to solve the problem.Specifically,the PTT scheme is executed on the distributed switch side,the controller to schedule and select routing policies.Moreover,a tracing probabilistic optimization is embedded into the PTT scheme to accelerate path reconstruction and save device resources.Simulation results show that the PTT scheme can reconstruct address spoofing packet forward path,reduce the resource consumption compared with existing tracing scheme.Data tracing audit method has fine-grained detection and feasible performance.

家庭医生服务制度的健康伦理、现实挑战与机制完善

人文关怀、契约精神与资源分配是家庭医生服务制度健康伦理的核心指向,该制度在实践运作中存在诸多健康伦理的现实挑战。人文关怀理念的培养,必须强化全科医学人文教育的规范化与家庭医生执业中人文教育的制度化;签约服务信任关系的养成,应力求实现家庭医生服务制度的规范化且应充分考虑不同人群的特殊需要,加强家庭医生服务平台的信息化建设;签约服务首诊秩序的形成,除了人文关怀理念与签约服务信任的相关制度完善外,还应采取诱导性的制度设计,合理调整与配置医疗卫生资源,引导居民逐步养成科学的健康理念与有序的就医习惯。

农业社会化服务与小农户的组织化:不同服务模式的比较

本研究通过对比政府主导型、市场主导型和村集体经济组织主导型社会化服务模式,讨论了小农户如何被组织起来以及组织成本由谁承担的问题。在由政府主导的社会化服务模式中,小农户因受到政府补贴的吸引而达成了临时的合作,但这种组织化具有暂时性。在市场主导型社会化服务模式中,小农户或被整合到规模经营主体的种植模式中,或被服务组织重塑。在这两种服务模式中,小农户都是被动的参与者,其组织化程度并未提高。村集体经济组织可能通过重建与小农户的双向权责均衡关系,通过收取服务费用的方式来解决组织成本问题。这种双向的权责均衡关系使村集体经济组织与小农户之间建立起有机的利益联结,从而使该组织对小农户的组织和动员成为可能。

能源法的法权构造及其体系展开

能源法的核心范畴界定较为模糊,亟待澄清。基于能源权利与能源权力的交互性、能源公益与能源私益的均衡性、能源监管与能源市场的协调性等需求考量,法权可作为能源法的核心范畴。能源法法权结构可从本体论、运行论和价值论三个层面予以构造,形成体系化安排。本体论上,应以公民能源权利与国家能源权力的交互为基础,强调公民能源权作为法权结构的逻辑起点、以落脚为能源普遍服务的能源权力作为法权结构的基本保障;运行论上,应以能源合同作为法权结构运行的具体承载;价值论上,应以能源正义作为法权结构价值的最终目的。由此,可仰仗能源法的法权结构构筑能源法学体系。
