Decision Making System

The service purchaser needs to stipulate for the service. The service contributor will afford the service to the purchaser.The powerful use of services to assemble business processes in service computing pressures that the Quality of Services (QoS) convene consumers’ perspective. When  manipulating the services, a service provider must  set apart the quality of service levels that will be existing to the  customers. Programmed web-based negotiation of Service Level Agreements (SLA) can assist in describing the QoS necessities of critical service-based processes. We put forward a trusted Negotiation Organizer(NO) structure that performs adaptive and intelligent mutual bargaining of SLAs between a service contributor and a service purchaser based on each party’s elevated level business necessities. We also define an algorithm for adapting the decision functions during an continuing negotiation to match with an opponent’s offers or with simplified purchaser preferences. The NO uses intelligent agents to conduct the negotiation locally by choosing the most suitable multi criteria decision making system known as Analytic Hierarchy Process (AHP).

Auto Scaling

Auto-scaling is one of the most important features in Cloud computing. This feature promises cloud computing customers the ability to best adapt the capacity of their systems to the load they are facing while maintaining the Quality of Service (QoS). This adaptation will be done automatically by increasing or decreasing the amount of resources being leveraged against the workload’s resource demands. There are two types and several techniques of auto-scaling proposed in the literature. However, regardless the type or technique of auto-scaling used, over-provisioning or under-provisioning problem is often observed. In this paper, we model the auto-scaling mechanism with the Stochastic Well-formed coloured Nets (SWN). The simulation of the SWN model allows us to find the state of the system (the number of requests to be dispatched, the idle times of the started resources) from which the auto-scaling mechanism must be operated in order to minimize the amount of used resources without violating the service-level agreements (SLA).

The article considers the concept of hotel services quality, and pays special attention to the fact that service level depends on the focusing of staff on customer. An important condition for the successful operation of a small hotel is its orientation towards the consumer, consisting in enhance the perceived value of the service, in meeting its needs and, as a result, in achieving customer loyalty. Focusing of employees on customer is one of major factors of ensuring efficiency of activities and competitiveness of hotel. The author researches the quality assessment of the small hotels services in Novosibirsk. The main problems in rendering hotel services revealed by author are related to technical, functional and social service quality. Virtually all aspects of activities of small hotels have shortcomings showing the lack of system approach to management, despite the size and an organizational structure of enterprises which assume mobility and flexibility of management, fast adaptation to a market situation, requests of consumers, a high susceptibility to innovations. The author offers the recommendations for improving activities of small hotels, implementation of which will allow to increase hotel services quality. The management of small hotels of the Novosibirsk should pay attention to the following parameters: material and technical resources, quality standards, corporate culture, corporate style, staff policy, technologies of servicing, organization of business processes, range of services, price policy, and marketing communications. The service quality improvement should be complex and cover all activities of hotel. To hold the client, the enterprises of the industry of hospitality need to motivate the employees, to improve quality of the provided services, raising degree of a customer satisfaction and creating its loyalty of the organization.

Service Consumer

Service Level Agreement (SLA) is an agreement between the service provider and consumer to provide the verifiable quality of services. Using the valuable metrics in SLA, a service consumer could easily evaluate the service provider. Though there are different types of SLA models are available between the consumer and provider, the proposed approach describes the Fuzzy rule base SLA agreement generation among multiple service providers. A negotiation system is designed in this work to collect the different sets of provider services. With their desired quality metrics, a common Fuzzy based SLA report is generated and compared against the existing consumer requirements. From the analysis of the common agreement report, consumers can easily evaluate the best service with the desired Impact service, cost and Quality. The main advantage of this approach is that it reduces the time consumption of a consumer. Moreover, the best service provider can be selected among multiple providers with the desired QoS parameters. At the same time, the bilateral negotiation is enhanced with the approach of multilateral negotiation to improve the searching time of consumers.

Analytic Hierarchy

In order to evaluate the quality of the air passenger service objectively and accurately, based on analyzing the characteristics of comprehensive evaluation of service level, and applied the theory of Maslow’s hierarchy of need, the evaluation index system of air passenger service quality has been built from six aspects, such as objective, economy, service, quickness, comfort and convenience. The evaluation index weight vector is determined by means of the improved analytic hierarchy process. The fuzzy theory is used for comprehensive evaluation, and the model is analyzed through example. The results show that the evaluation system can effectively reflect the level of air passenger transport service quality and reduce the influence of human factors.
