In this paper, we present a variant of Datalog language (we call it Datalog ) able to deal with weights on ground facts and to consequently compute a feedback result for the goal satisfaction. The weights are chosen from a proper c-semiring. In our context, our goal is to use this language as a semantic foundation for languages for expressing trust relationships. As a matter of fact, many of th...

Sharing sensitive information across security domains is an important requirement for knowledge intensive collaborative work, but such sharing may impose risks on security and privacy integrity. Research has increasingly recognized the role of trust in minimizing the risk of information sharing across untrusted or unknown entities. To this extent, trust negotiations[1][3][15][20] have emerged a...

This paper studies an integrated optimization problem on outsourcing and production decisions in the context of the global supply chain and China’s export-oriented tax policies. A three-stage decision model is proposed for this integrated optimization problem. A crossentropy-based solution method is also developed to solve the three-stage decision model. Numerical experiments are performed to i...

In an analysis to find ways of measuring the design and effectiveness of hospital audit, therefore, seven main measures emerged t...

This study differs from previous ones applying multivariate statistical analysis and multiple criteria decision-making (MCDM) methods. We use the Variable Consistency Dominance-based Rough Set Approach (VC-DRSA) to formulate airline service strategies by generating airline service decision rules thatmodelpassengerpreferences for airline servicequality. Flowgraphsare applied to inferdecision rul...
