Cloud computing is an emerging new computing paradigm designed to deliver numerous computing services through networked media such as the Internet. This solution offers many possibilities that did not exist before for all enterprises but especially for small and medium sized companies, which very often cannot afford for huge investments in contemporary IT solutions. The aim of the paper is an attempt...
In the dynamic environment, organizations are required to build their competitive advantage not only on own resources, but also on resources commissioned from external providers, accessed through various forms of sourcing, including the sourcing of IT services. This paper presents some of the aspects of information security, in the context of the modern implementation of new IT sourcing methods. IT...

The companies that know customer expectation can deliver services/products of superior quality compared with those services provided by conceivable competitors, this is the key for the company success in the modern era. This paper...
The aim of this study is to propose an objective method based on a new measure of intuitionistic fuzzy information, called knowledge measure for determining weights of attributes (also called criteria) in a real-world multicriteria decision making problem under intuitionistic fuzzy environment. To address this issue, we first analyze the existing entropy measures and show that their use in objective...
The multi-agent is now an established research topic of epistemology, in the view of ontology, multiagent is usually related to role and agent is the executor of role, in this paper, we take research on multi-agent by solving the problem of RBAC role-permission assignment with conflicting constraints: the formalization, the description of conflict, and the algorithm are given based on the E-CARGO...
Workflow Management Systems (WfMSs) help big enterprises in automation of their business processes and thus help the management to take critical decisions fast. The WfMSs can be combined with the power of Cloud Computing to harness the strengths of both the technologies. The use of WfMSs for critical and strategic applications, which is common in case of business and scientific community, gives rise...
Based on the triangular norms, some new operational laws of linguistic variables are defined. They can remedy the defects of some existed operational laws. The desirable properties of the new operational laws are studied. Within the situation of the defined linguistic operational laws, an extended linguistic weighted arithmetic averaging (ELWAA) operator is proposed to aggregate the linguistic information...
Customer switching behavior refers to the action of a customer switching from one supplier of a product or service to another one. Among competing facilities, this behavior can be described as a customer switching from a facility, providing a certain kind of service, to a similar facility. In reality, customers in congested facilities are more prone to switch. Competitive location model presented...
Because of the economic globalization, products are manufactured in one place and sold all over the world. As freight cost accounts for a large part of the total costs for these products, it plays a more important role in the management of inventory. Recent years, phenomenal growth of successful deployments of innovative pricing strategies in a variety of industries makes scores of retail and manufacturing...
In a competitive environment, competing agents would maximize their ideas' influence for higher profits. For example, in an unsaturated market, when a new company participates in the market sharing competition, it would distribute free tryout or discount to several customers, let them adopt the product or service, and influence others to use this product as propagation goes. This situation can also...
Nowadays, companies are increasingly offering their business services through computational services on the Internet in order to attract more customers and increase their revenues. However, these services have financial costs that need to be managed in order to maximize profit. Several models and techniques have been recently reported that aim at managing, controlling and reducing service costs. However,...
Quality is a mainstream issue for Websites and Web-based systems. Analysts, designers and developers can choose from a variety of models and methods to design and evaluate quality Websites. However, our experience, both as users and professionals, is too often disappointing. Besides usability, the most known of the factors contributing to a Website's quality, there are a large numbers of other features...
This paper presents an overview of various interrelated Cloud technologies and presents a framework for use in the creation of a Cloud based asset management application. The full potential of the application of Cloud based services are still to be realised by corporates and in this paper the possibilities of mobile applications within an organisational environment is highlighted in the form of a...
It is important to implement a continuous improvement when analyzing the life cycle of Business Process (BP). As a result, organizations are searching for tools like Business Process Management (BPM) using Business Process Management System (BPMS). The Workflow Management System (WfMS) is the most significant BPMS that is used to automatically improve the business process. Organizations require virtual...
Nowadays, cloud computing has become a relatively popular approach between those businesses that would like to be agile, flexible and provident. For these purposes many companies have started to transfer all or parts of their business processes to the cloud platform. In this paper cloud migration process of a sample company has been studied through a case which is a company. Since current accounting...
Recent years have seen the popularization of model based development (MBD) using models based on block diagrams. In many mechatronics systems, including automobile engine control and the brake control, a closed loop control is used to manage controls based on feedback data from control target objects. In order to develop a closed loop control using model base, a plant model that simulates the behavior...
Cloud computing has recently emerged compelling paradigm by introducing several characteristics such as on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. Despite the fact that cloud computing offers huge cost benefits for companies, the unique security challenges have been introduced in a cloud environment that make risk assessment challenging...
In public vs. private solutions (i.e. Cloud vs. In-house, or leased vs. Owned) for storage, both alternatives have their pros and cons. Cloud storage can easily adapt to the company needs, but exhibits a higher unit cost than in-house solutions. On the other hand, if the company relies on its own storage equipment, it must periodically purchase it on the basis of forecasts, which may prove imprecise...
An interval estimate is provided for the Herfindahl-Hirschman Index (HHI) when the knowledge about the market is incomplete, and we know just the largest market shares. Two rigorous bounds are provided for the HHI, without any further assumptions. Though the interval gets wider as the sum of the known market shares gets smaller, the estimate proves to be quite tight even when the fraction of the market...
Cloud Computing provides great opportunities especially for companies within the SME segment. This is why Cloud Service Providers (CSPs) are increasing their efforts to make their infrastructure accessible for small companies to help them compensate the lack of their own IT infrastructure. But nevertheless a lot of companies - especially smaller ones - are not yet convinced of the benefits of cloud...
