Multiple Metrics

New web technologies have encouraged the deployment of various network applications that are rich with multimedia and real-time services. These services demand stringent requirements are defined through Quality of Service (QoS) parameters such as delay, jitter, loss, etc. To guarantee the delivery of these services QoS routing algorithms that deal with multiple metrics are needed. Unfortunately, QoS routing with multiple metrics is considered an NP-complete problem that cannot be solved by a simple algorithm. This paper proposes three source based QoS routing algorithms that find the optimal path from the service provider to the user that best satisfies the QoS requirements for a particular service. The three algorithms use the same filtering technique to prune all the paths that do not meet the requirements which solves the complexity of NP-complete problem. Next, each of the three algorithms integrates a different Multiple Criteria Decision Making method to select one of the paths that have resulted from the route filtering technique. The three decision making methods used are the Analytic Hierarchy Process (AHP), Multi-Attribute Utility Theory (MAUT), and Kepner-Tregoe KT. Results show that the algorithms find a path using multiple constraints with a high ability to handle multimedia and real-time applications.

Best Worst Method

Choosing the best schools from a group of schools is a multi-criteria decision-making (MCDM) problem. In this paper, we have represented a method that uses the fusion of two multi-criteria decision-making methods, Best–Worst Method (BWM) and Analytic Hierarchy Process (AHP), to rank some of the user preferred alternatives. The system considers the choice of the user and the quality of the alternatives to rank them. User preferences on the criteria are taken as inputs in the form of best–worst comparison vectors to measure the choice of the user. These values are applied to calculate the numeric weights of each of the criteria. These weights reflect the preference of the user. A dataset of secondary schools in Bangladesh has been compiled and used for automatic quantitative pairwise comparison on the alternatives to calculate the score of each alternative in every criterion, which reflects its quality in that criterion. These scores are calculated using AHP. The weights of the criteria as well as the scores of these alternatives in those criteria are then used to calculate the final score of the alternatives and to rank them accordingly. An extensive experimental analysis and comparative study is reported at the end of this paper.

It Operations

In the UK, 88% of companies utilise some form of outsourcing of their Information Technology (IT) operations. The evidence from the literature indicates that approximately 50% of these outsourcing decisions results in complications and in some cases failure. There is a need for outsourcing management frameworks to provide strategic direction and guidance in the decision-making process. This chapter describes the application of one such framework, known as the Holistic Approach {Business, Information, Organisation} (HABIO) framework, to two major commercial organisations indicating financial assessment, monitoring information for performance and quality of service which can be incorporated into service operations and benchmarking criteria.

Creating and updating meal tags, printing them on small-sized papers raise the costs, cause workload and affect the service quality negatively at the hotels with all-you-can-eat buffet system. Over the last few years, we have seen that many hotels started to make use of tablets to improve the service quality, decrease the costs, provide customers ability to order foods, make reservations, manage their rooms, etc. Going paperless and including more features by adopting new technologies increase the quality of service, help customer's and staff's decision-making processes more effective, improve customer and service personnel experience. In this chapter, authors designed and developed a flexible, cost effective, easy-to-use, customer-friendly and staff oriented paperless buffet management system for the restaurants that have all-you-can-eat buffet. Through this system, they aimed to achieve enhanced customer service, increased efficiency and customer satisfaction; save time, paper and printing costs; provide environmental benefits and efficient buffet management.

Event Service

The proliferation of sensor devices and services along with the advances in event processing brings many new opportunities as well as challenges. It is now possible to provide, analyze and react upon real-time, complex events in urban environments. When existing event services do not provide such complex events directly, an event service composition maybe required. However, it is difficult to determine which event service candidates (or service compositions) best suit users' and applications' quality-of-service requirements. A sub-optimal service composition may lead to inaccurate event detection, lack of system robustness etc. In this paper, the authors address these issues by first providing a quality-of-service aggregation schema for complex event service compositions and then developing a genetic algorithm to efficiently create near-optimal event service compositions. The authors evaluate their approach with both real sensor data collected via Internet-of-Things services as well as synthesised datasets.

The Impact

Purpose The purpose of this paper is to use multi-criteria decision-making methods to assess environmental quality of the Organization for Economic Co-operation and Development (OECD) countries. Design/methodology/approach Weights of criteria are determined by means of entropy weight method. VIKOR method is used to rank different OECD countries based on their environmental quality. Findings The results show the best and the worst environmental quality of different OECD countries. The top five countries of environmental quality are Spain, Israel, Belgium, Japan and the USA. These countries have the best quality of environment. By contrast, the worst five countries of environmental quality are Iceland, Australia, New Zealand, Canada and Chile. Originality/value The findings have implications regarding environmental quality. The results suggest that governments should engage in policy-making that improves their environmental quality. Specifically, those having poor quality of environment should protect the environment and reduce the negative impact on environment. For example, reduce emission of CO2 to lessen the impact of climate change, improve the quality of air and water, reduce waste generation, increase biodiversity and enhance forest resources. Improvement of environmental quality will improve our social and economic life as well as health conditions.

Promethee Method

Education has a very decisive role, not only for the development and manifestation of individuals but also for the development of a nation and a state. The progress of a culture depends on how that culture recognizes, appreciates, and uses its human resources. This is closely related to the quality of education provided to members of the community. The word decision means choice, namely the choice of two or more possibilities. Decision making is hardly a choice between right and wrong but what often happens is a choice between "almost right" and "maybe wrong". Decision making in an organization is the result of a continuous process of communication and participation from the entire organization. The results of these decisions can be statements that are agreed between alternatives or between procedures to achieve certain goals. However, to be able to determine the best decision, there are several methods that can be used to build a decision support system, one of which is Promethee. The promethee method is included in the Multi Criteria Decision Making (MCDM) group solving or multiple criteria decision making which is a discipline that is very important in making decisions on a problem that has more than one criterion (multicriteria).
