“…Since the Gini coefficient can reflects the data difference between different evaluation objects, Li et al [31] proposed a method to calculate the weights of objectives based on the Gini coefficient: Suppose that G k denotes the Gini coefficient of the k-th criterion (k = 1, 2, · · · , n), m denotes the total data of a specific criterion, y ki denotes the i-th alternative' performance value under the k-th criterion, E k denotes the expectation value of all alternatives' performance values under the k-th criterion. Then the Gini coefficient value G k can be calculated by Equations (8) and (9) [31].…”

Sustainable Cloud Service Provider Development by a Z-Number-Based DNMA Method with Gini-Coefficient-Based Weight Determination

et al. 2020

The sustainable development of cloud service providers (CSPs) is a significant multiple criteria decision making (MCDM) problem, involving the intrinsic relations among multiple alternatives, (quantitative and qualitative) decision criteria and decision-experts for the selection of trustworthy CSPs. Most existing MCDM methods for CSP selection incorporated only one normalization technique in benefit and cost criteria, which would mislead the decision results and limit the applications of these methods. In addition, these methods did not consider the reliability of information given by decision-makers. Given these research gaps, this study introduces a Z-number-based double normalization-based multiple aggregation (DNMA) method to tackle quantitative and qualitative criteria in forms of benefit, cost, and target types for sustainable CSP development. We extend the original DNMA method to the Z-number environment to handle the uncertain and unreliability information of decision-makers. To make trade-offs between normalized criteria values, we develop a Gini-coefficient based weighting method to replace the mean-square-based weighting method used in the original DNMA method to enhance the applicability and isotonicity of the DNMA method. A case study is conducted to demonstrate the effectiveness of the proposed method. Furthermore, comparative analysis and sensitivity analysis are implemented to test the stability and applicability of the proposed method.Sustainability 2020, 12, 3410 2 of 17 future generations to meet their own needs" [2]. Sustainability requires sustainable business practices. For doing so, information systems play an important role in the organization transition towards sustainability initiatives. The sustainable information systems have been considered as an opportunity for organizations to improve productivity, reduce costs, and increase profitability [3]. The flexible, elastic and agile nature of cloud computing provides an opportunity for governmental, academic and business organizations to consider migrating their existing applications to cloud environments to make their business processes agile with minimal cost and management effort [4]. Due to the increase in the number of cloud service providers (CSPs) offering functionally similar cloud services with varying cost, features and quality, it becomes extremely complex and burdensome to select a dependable, scalable, sustainable and high cost-effective cloud service for consumers to fulfil and satisfy their requirements and business strategies. There is a pressing need of comprehensive techniques to help them for the sustainable CSP development [5,6].Sustainable CSP development can be formulated as a multicriteria decision-making (MCDM) problem [5]. It involves the intrinsic relations among multiple alternatives, (quantitative and qualitative) decision criteria and experts for selecting the trustworthy CSPs. Moreover, the CSP evaluation data often involves uncertain, unreliability, multi-scale and imprecise weights of quality of service (QoS)...

“…Statistical analyzes on the different randomly generated task graphs are applied to estimate the verification results. Rafieyan et al 23 studied the problem of cloud scheduling based on a combination of the concept of the multi‐criteria decision‐making method and compromise ranking method (VIKOR) in virtualized heterogeneous systems, while considering three levels of priorities, including scheduling level, resources level, and job level. The authors have investigated the effect of priority of each job in compared with other jobs separately using comparison matrixes of jobs.…”

The massive growth of cloud computing has led to huge amounts of energy consumption and carbon emissions by a large number of servers. One of the major aspects of cloud computing is its scheduling of many task requests submitted by users. Minimizing energy consumption while ensuring the user's QoS preferences is very important to achieving profit maximization for the cloud service providers and ensuring the user's service level agreement (SLA).Therefore, in addition to implementing user's tasks, cloud data centers should meet the different criteria in applying the cloud resources by considering the multiple requirements of different users. Mapping of user requests to cloud resources for processing in a distributed environment is a well-known NPhard problem. To resolve this problem, this paper proposes an energy-efficient task-scheduling algorithm based on best-worst (BWM) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) methodology. The main objective of this paper is to determine which cloud scheduling solution is more important to select. First, a decision-making group identify the evaluation criteria. After that, a BWM process is applied to assign the importance weights for each criterion, because the selected criteria have varied importance. Then, TOPSIS uses these weighted criteria as inputs to evaluate and measure the performance of each alternative. The performance of the proposed and existing algorithms is evaluated using several benchmarks in the CloudSim toolkit and statistical testing through ANOVA, where the evaluation metrics include the makespan, energy consumption, and resource utilization.

The tasks are offloaded to fog computing instead of cloud computing to enhance the quality of service (QoS) of internet of things (IoT) applications. Though it provides improved QoS the accessibility of unremitting computation properties of fog servers is one among the limitations of IoT applications as transmitting a huge quantity of data may induce more energy consumption, cost, and increased makespan. Much research has been made to build up an efficient technique to address the multi-objective task scheduling in fog computing. One such method used to solve multiple objective problems in different domains is multi-criteria decision-making methods (MCDM). The MCDM Method named complex proportional assessment (COPRAS) has risen in popularity due to simple and fast computation. In this paper, a task scheduling algorithm (ECOPRAS) based on the integration of the entropy weight method and COPRAS method is proposed. The proposed technique consists of two phases that is, Task prioritization, and Task assignment. In the first phase, the task is ordered based on the heuristic method, B-level and in the second phase, the task will be assigned based on the ranking provided by the ECOPRAS method. The proposed method aims at minimizing energy consumption, price, and makespan and maximizing the reliability and utilization rate. The simulation results are compared with similar algorithms through various workflows and the proposed method outperforms well.
