In this study, a spectrum allocation algorithm is proposed to reduce the cost and the packets loss rate in the communications between the utility company and the consumers. We establish a cost model based on spectrum allocation in smart grid. Specifically, the subbands are allocated to different data aggregator units (DAUs) according to the confidence level and the maximum cost requirements. The maximum...
Grid computing, was developed by computer scientists in the mid 1990's based on ease of use and access geographically distributed resources which are dynamic and heterogeneous for solving difficult problems. These distributed resources are owned by different organizations. Grid computing provides a framework for parallel/distributed computing. For developing a grid, low-level services (secure access...
Consider the diversity of users' traffic types, we investigate the problem of distributed carrier aggregation in cognitive small cell networks. In most existing carrier aggregation (CA) researches, they aimed to optimize the throughput or to mitigate the interference. However, in practical wireless communication users' quality of experience (QoE) is the ultimate concerning. Different QoE functions...
This paper represents to solve the redundancy allocation problem (RAP) occurring in optimization technique. The past research of RAP is basically single objective, which is focused on optimization of only one objective. We can genuinely combine more important aspects like cost, volume and weight to this which will lead to a multiple objective redundancy allocation problem (MORAP). The objective of...
Due to expensive procurement cost and high operating cost, Magnetic Resonance Imaging (MRI) is usually one of bottleneck resources in hospitals. As MRI is shared by multi-types of patients with different requirements of examinations, setup time is needed to change coil between different patient types. Therefore, the same type patients are arranged in a sequential order to reduce setup time. This paper...
Minimizing the total allocation cost is an unavoidable issue needing to be deal with in task scheduling of cloud computing for processing all the tasks. In this paper, the comparative study has been done among the priority algorithms and secondly between the priority and non-priority task scheduling algorithms. In order to emulate the precedence relation of task, the task scheduling algorithms enumerate...
The aim of survey design is to obtain optimum precision at minimum cost. Stratification is one of the commonly used methods of survey design. When using stratification one of the main problems to consider is the determination of optimum strata boundaries. This paper will discuss how to determine the optimum strata boundaries when the measurement cost per units varies across the strata. The problem...
In this paper, a probabilistic production simulation (PPS) based on the equivalent energy and frequency function method is proposed to analyze the power supply reliability and the production cost of a wind-photovoltaic (PV) hybrid generation system. Compared with the wind power generation system that has the same installed capacity, the wind-PV hybrid generation system increases the value loss of...
We present a method and a tool for devising adaptation plans for the deployment of software applications on cloud computing infrastructure comprising a combination of reserved and "pay-as-you-go" resources. Starting from a trace log that represents the expected workload pattern of the application, we exploit queuing theory results to synthesize an adaptation plan that manages the cloud elasticity...
We have compared the total cost of an innovative elastic network with respect to the conventional WDM ones operating in realistic network scenarios. The results give an insight of the cost benefits that can be obtained with an elastic OFDM-based network for the operation of future optical transport networks with different protection schemes.
This article regresses the data of settlement and litigation from a Life Insurance Stock Company Limited in Beijing during the period of 2005–2008, finding that the insurer's indemnities adjudicated by a judge is far less than the amounts offered by a policyholder, being little correlated with amounts offered by a policyholder while related strongly to indemnities accepted by an insurer. District...
With the promise on-demand compute/storage resources, many users are deploying data-intensive scientific applications onto Clouds. To accelerate these applications, the prospect of caching intermediate data using the elastic compute and storage framework has proved promising. To this end, we believe that an in-depth study of cache placement decisions over various Cloud storage options would be highly...
Resource management and scheduling using economic-based principles and market-oriented models have been proven to be useful for scheduling tasks in Computing Grid. However, most studies only focus on the single objective of either cost or makespan. In this paper, we consider both cost and makespan, and focus on scheduling parallel tasks from Grid users considering a commodity market. A cost and time...
At present, China's small and medium enterprises (SMEs) develop rapidly, they play an important role in developing regional economy, creating employment opportunities, meeting consumers' demand, innovating management system and other aspects. They become an important component of China's national economy. This thesis analyzed the status and characteristics of SMEs in China, deeply discussed the problems...
This paper studies the replenishment problem in a single item, multi-supplier environment. A cost optimal model is presented. A comparative analysis with singe supplier model showed the difference in two conditions. An extended model based on model in MTP is proposed when considering the time and production capability constraints in MTO and shows the management issues in organizing MTO supply chain.
There is a great surge of interest recently in the fixed-mobile convergence from the telecom industry. This is supported by strong 3G operator interest in using the broadband penetration as a spring board to achieve cost effective delivery of the multimedia data for indoor coverage. Statistics indicated that more than 70% of the calls are made from end-users in indoor environments. Based on this trend,...
This paper studied the outsourcing of human resources management from economic view. The theory of transaction cost, game theory and the principal-agent theory were used to study decision making, monitoring and incentive compensation of the outsourcing for the service provider. The essentials of human resources management outsourcing were analyzed and summarized. The aim of this study is to provide...
Distribution center is a bridge connecting providers and clients. It plays an important role in logistics system. This paper put forward the least cost and the shortest time allocation models of materials distribution center. The integrated measure allocation models of materials distribution center considering the time and the cost together is built and a solution flow to the least cost and the shortest...
The proper application of incentive mechanism in construction project can decrease project cost. However, current incentive methods donpsilat consider the change of human needs in construction and are inadequate to analyze the impacts of incentive factors allocation on project risk and cost due to the complexity and dynamics of the project in a real world. And therefore, there is a need for a model...
In this paper, an adaptive algorithm for the dynamic network which can be affected by a variety of factors, is proposed. Because of resource utility rate and the dynamic state of the wireless network, different protocols have different costs. The proposed algorithm can select an appropriate protocol that has the lower cost. The simulation results show that the proposed adaptive algorithm is realizable...
