Improving customer satisfaction is important in order to create a good relationship between a company and its customers which will give benefit to both sides. One way to accomplish it is by conducting quality improvement. Quality improvement has a strong relationship with the customer satisfaction, so it is an important issue in manufacturing. This paper discusses an optimization model to allocate...
Various techniques of portfolio selection are applied to interpret the status of the market and predict the market's future trend, but they are not beneficial to small investors because these techniques should be administered by an expert. In addition, these techniques desire accumulation of data about the market and complicated calculations, which is too much effort for individual small investors...
Electricity deregulation and the increase of renewable energy penetration are playing an important role in developed countries. In this work, a study of the decision-making process of energy traders is presented. We develop a theoretical solution for the sourcing trade-off, that a utility company faces when designing its long-term energy allocation strategy. The market mechanism of long-term contracts,...
Each company continually has to choose the projects in which to invest, among the numerous proposals submitted by company departments. Just a few projects among those put forward for funding can be actually accepted, due to the unavoidable discrepancy between available money and required investments. Though overall profit maximization could appear as the natural allocation goal, it is to be considered...
In the case of electricity market reform, the electricity market is becoming increasingly active, and transacted electricity quantity is growing unceasingly and the tradable format is on the increase. Because of the limited energy resources, the level of transaction efficiency has become the focus of attention. In the face of resources diversity of electricity purchasing and selling, power grid carries...
This study aims to construct a scientific model in estimating effort and cost of software development projects. Use Case Points (UCP) is very important method to estimate the total effort in software development projects. While the technique of Activity-based Costing (ABC) serves as the calculation of costs in each of the activities, especially the allocation of project resources. ABC technique consists...
In Industry 4.0 the optimal allocation of a pool of available workers is a very important issue. Solving this problem can improve the performance of the company and the life of workers with positive returns on productivity. Moreover, from a computational perspective, this problem is extremely interesting because it could have a combinatorial explosion and become very hard to solve. In this paper,...
Task allocation problems have focused on achieving one-shot optimality. In practice, many task allocation problems are of repeated nature, where the allocation outcome of previous rounds may influence the participation of agents in subsequent rounds, and consequently, the quality of the allocations in the long term. We investigate how allocation influences agents' decision to participate using prospect...
Recent increases in the adoption of Online Social Networks (OSNs) for advertising has resulted in the research and development of algorithms that can maximize the resulting revenue. OSN users are likely to be influenced by their friends; therefore, one can leverage friendship relationships to determine how advertisements should be distributed among users. If a user is given an indication that their...
In the article we consider the implementation of the matrix information management project technology in the form of PRP-system, which is an example of a new class of Project Management systems. The functions, structure and components are described. Also we represented its unique advantages over existing traditional Project Management information systems, e.g. simulation modeling and product planning.
In a deregulated electricity supply required method of determining the actual power flow on each line of the generator to load. This paper is a study to solved the problem of the utilization of transmission by using the distribution factor method. The main purpose of this paper is to provide a new scheme for determining the utilization of the transmission line. The proposed method was verified on...
Datacenter-based Cloud Computing services provide a flexible, scalable and yet economical infrastructure to host online services such as multimedia streaming, email and bulk storage. Many such services perform geo-replication to provide necessary quality of service and reliability to users resulting in frequent large inter-datacenter transfers. In order to meet tenant service level agreements (SLAs),...
Although there are vast potential locations to install FACTS devices in a power system, the actual installation number is very limited due to economical consideration. Therefore the allocation strategy exhibits strong sparsity. This paper formulates FACTS device allocation problem as a general sparsity constrained OPF problem and employs Lq(0 <q < 1) norms to enforce sparsity on FACTS devices...
The growth in the packaged food industry has created pressure on the packaged food warehouse to enhance the order-picking efficiency. The decision support system (DSS) for stock keeping units (SKUs) allocation thus has to make quality decisions for shortening the order-picking time. In order to improve the decision making ability of the DSS, the determinant factors of the major input variable - the...
Nowadays there are more than 10 billion sensors in the Internet of Things. These sensors will produce a mass of historical data as time goes on. And these data are useful in data mining and may create great value for human. However, historical sensor data are hard to archive because they have the characteristics of mass, complexity, isomerism and dynamic nature. Therefore, how to archive historical...
Based on the social exchange perspective, this paper explore the relationship between high-performance work systems and the employee job satisfaction, and analyze the mediation effect of organizational identification. Through more than 200 employees at different levels in the enterprise investigation and using hierarchical regression analysis to deal with the data, the results show that: (1) High-performance...
Container transportation is a significant guarantee to the realization of many international trades and playing a significant role in the transactions across borders. Empty container allocation and management relate to the degree of container utilization, the cost of empty container disposition expenses, adaptation for containers of goods sent in a timely manner and enterprise economic benefits. Through...
At present, China's express market demands and supply capacity of the express service providers is increasingly prominent. In the view of the problems such as scattered, small, bad in the express industry in China, the collaborative mode of service network based on horizontal resource integration is proposed. Through the cooperative operation of the express enterprise service network, it is not only...
Though there are many less-than-truckload (LTL) companies, the LTL industry is still in a decentralized structure and the market is dispersive. Under the influence of economic recession and regional restriction in self-development, LTL companies urgently form a collaborative logistics network that is based on each's existed facilities and networks to make up their own deficiencies, share resources,...
With the deterioration of environment, the government and the companies which have strong consciousness of environmental protection make sure their own emissions reduction targets to reduce the emissions of CO2. In addition, the government also introduced all kinds of subsidy policies to encourage the industry to reduce the emissions of CO2. For companies, they often tend to cooperate with their upstream...
