The open XXZ spin chain with the anisotropy parameter $\Delta=-\frac12$ and diagonal boundary magnetic fields that depend on a $x$ is studied. For real $x>0$, exact finite-size ground-state eigenvalue of spin-chain Hamiltonian explicitly computed. In suitable normalisation, components are characterised as polynomials in integer coefficients. Linear sum rules special this eigenvector computed te...

The main thesis of this book is that while technology may change, economic laws do not. The authors, Carl Shapiro and Hal Varian point out that the information economy is driven by advances in information technology and infrastructure. What is new is, not the total amount of information available but our ability to manipulate information across industries. Technology is allowing people to do mo...

There is a problem of applying of combining rules to evidence which were got from different information sources in framework of Dempster-Shafer theory. In this work the conflict measure and index of decreasing of ignorance in frame of Dempster-Shafer theory are introduced for characterization of quality of applied combining rules. Those functionals are analyzed on the bodies of evidences of spe...

Through the emergence of information and communication technologies and customer-oriented approaches in business and industry, for achieving competitive advantages and in order to remain at the top in every business, more exible and responsive supply chain systems are required. The next generation of supply chain systems must be agile, adaptive, cooperative, integrated and exible. Agent-based s...

In a supply chain management context, the enterprise architecture concept to efficiently support the collaborative processes among the supply chain members involved has been evolving. Each supply chain has an organizational structure that describes the hierarchical relationships among its members, ranging from centralized to decentralized organizations. From a decentralized perspective, each su...

Agricultural products supply-chain finance, as one of the solutions to the issue of “capital problems” of agriculture, countryside and farmers, has proposed a kind of characteristics model to assess the risk of agricultural production, processing and marketing, which can improve the issue of farmers and enterprises lacking of funds. This model is proposed on the basis of uncertain information p...

The modern supply chain were more vulnerable to risk, supply chain risk mainly comes from many aspects of the internal and external environment, the supply chain industry products background, upstream and downstream supply chain relationship, decision support. The study found that the need to establish information sharing mechanism, multilevel supply chain defense system, the principal-agent me...

Traceability has emerged as a prime requirement for multi-tier and multi-site production. It enables visibility caters to the consumer requirements of transparency quality assurance. Textile clothing industry is one such example that requires traceability implementation address prevailing problems information asymmetry low visibility. Customers find it difficult access product data can facilita...
