We propose an adaptive service model that maximizes the amount of service that spectrum users (SUs) achieve from accessing DSA systems. The proposed model allows SUs to utilize available spectrum efficiently by enabling them to locate spectrum opportunities in a distributed manner, thereby maximizing the long-term rewards that SUs receive. In this model, SUs adapt their required level of service with...
The aim of the work is to review and analyze the ideas and possibilities of modeling social welfare optimization based on the essential premises of neoclassical schools on consumer choice optimization. The work explains current and often controversial conceptions of basic postulates of economic welfare. It deals with the problems of defining the functions of social welfare, conceptions about the principles...
In order to improve operation efficiency and customer satisfaction and to minimize the turnaround time of vessels at container terminals, a berth allocation problem (BAP) was formulated. An adaptive artificial fish swarm algorithm (AFSA) was proposed to solve it. Firstly, the basic principle and the algorithm design of the AFSA were introduced. Then, for a test case, computational experiments explored...
Designing a general model of human resources management information systems fitted on corporate strategy based on related research from domestic and foreign scholars. Additionally, Sanjiu Medicine Co., Ltd. has been adopted for case study, systematically elaborated processes and patterns of human resource management information systems fitted on corporate strategy. The results show that the establishment...
Loss allocation to each user based on fair and justice is the main content of electrical power transmission cost reasonable allocation in Electricity Market. Making use of the uniqueness of Shapley value and distinctive features of shapley theorem, power sources and load are regard as players in a union. That is transform power source to equivalent voltage source and load to impedance based on Thevenin...
An issue of considerable importance, involves the problem of how to simultaneously allocate a fixed input resources and set targets among a set of competing entities in an equitable way. Based on data envelopment analysis (DEA), the current paper proposes a new method for simultaneously allocating fixed input resources and setting targets to all decision making units (DMUs), in such a way that all...
Computational science increasingly relies on the execution of workflows in distributed networks to solve complex applications. However, the heterogeneity of resources in these environments complicates resource management and the scheduling of such applications. Sophisticated scheduling policies are being developed for workflows, but they have had little impact in practice because their integration...
In this paper, hierarchical holographic modeling (HHM) is used to identify the risks in transport PPPs under the perspectives of contractual nature of PPPs, institution and cultural environment, and inadequate supervision. Then, we propose that the traditional financial audit approach can not effectively control risk on PPPs, and furthermore, we give an analytic framework of audit supervision for...
Logistics companies are typical enterprises depending on the maintenance of customer relationships, in which the customers are important resources. The establishment of a supply chain management concept and the implementation of customer relationship management are propitious to improve the competitiveness of logistics enterprises. In this paper, the necessity of the implementation of customer relationship...
To improve developing level of forestry is essential to forestry eco-system and forestry industry. And input-output efficiency is the most important measure of forestry developing level. The paper calculates forestry input-output efficiency of 31 districts with DEA, and arranges them in the order of results through horizontal and longitudinal analysis. The paper compares and ranks the forestry input-output...
To achieve the goals of: (1) reflecting the value information of resource flows and points to the key areas for improvement in an enterprise, (2) providing effective decision-making in environmental and resource management, and (3) showing the direction of the enterprise's sustainable development, this paper develops the resource flow equation which includes three kinds of indicators: (1) resource...
The main purpose of human resources outsourcing is to improve enterprise's core competence, reduce transaction cost, then constitute game relationship between enterprise and outsourcing service provider because of outsourcing projects and benefit distribution. Through introducing the concept of fair entropy in this game problem, the authors build the dynamic game model to research on the benefit allocation...
In this paper, the minimal cost spanning tree interval game is studied. It is proved that the interval core is no empty when n=2. By introducing the concepts of the left game, right game of MCSTIG, and compositive, it is proved there exists a hyperplane with non-negative normal vector to separate L and R strictly. when the interval core of MCSTIG is empty. It obtained the sufficient and necessary...
In recent years, there have been increasing researches on the irrational, subjective and perceptual aspects of strategic management, indicating the influence of perceptual factors such as value, emotion and feelings on strategic decision-making. Based on a rational perspective, current mental model is divided into belief and knowledge and is regarded as a mechanism to explain human perception, decision-making...
Abstract-Linking the tobacco manufacturers and the end retail consumers, cigarette distribution does not only represent the service level of logistics, but also concerns the overall operation efficiency of an enterprise. However, problems such as poor management and high cost of distribution still exist and need to be solved urgently. Therefore, cigarette distribution centers must gradually promote...
The implication of outlay management of university library contains its budget, daily management and management systems. The paper probes into its evaluation which includes evaluation contents, weights and value numeration methods. Finally, the paper sets forth results of university library outlay management and carries on the case analysis.
Material procurement is the very first link in the course of construction project, which relates to project cost, quality, and time limit and so on. Therefore, the selection of supplier is particularly important. In this paper, a two-stage model of supplier selection in project has been constructed by rough set and multi-objective liner programming based approach. The application of rough set based...
As the complexity of under the condition of large-scaled resource-constrained multi-project duration optimization problems, it is difficult to give its analysis solution. With the network technology in this paper, taking the minimum number of the multi-project weighted duration as the goal, then establish a mathematical model for the optimization problem. In view of the basic cellular automaton topological...
On the base of character of quality and quantity of mine water, ant colony algorithm is applied to optimize the site of purification plant. Aiming to industry, irrigation of agriculture, water supply of ecologic and living rural and urban residents, setting the maximum of net yield water supply, environment efficiency and society overall efficiency as object functions, using the capacity of water...
Based on the concept of multi-project management, it is pointed out that the key to multi-project management of real estate enterprises is to solve the strategic problems, resource problems and coordination problems. The functions of the project management office is evolved with the specific needs of enterprise project management, this paper will introduce the organizational form of Project Management...
