In the contemporary era, the importance of information is undisputed, but there has never been a common understanding of information, nor a unanimous conclusion to the researches on information metrics. Based on the previous studies, this paper analyzes the important achievements in the researches of the properties and metrics of information as well as their main insufficiencies, and discusses the...
Location privacy has been a serious concern for mobile users who use location-based services provided by the third-party provider via mobile networks. Recently, there have been tremendous efforts on developing new anonymity or obfuscation techniques to protect location privacy of mobile users. Though effective in certain scenarios, these existing techniques usually assume that a user has a constant...
In this paper, a new idea on the enterprise relative diathesis evaluation approach has been proposed based on the other evaluation theory and approach, which is based on balanced scorecard and together with diathesis-decided dynamic principle, and thus combined the operation surroundings with the enterprise relative diathesis evaluation effectively. Then the evaluation model is proposed with the weighted-numbers...
This paper presents a new fuzzy chance-constrained programming model to find the Pareto solution set for multiproject and multi-item investment combination based on the perspective of real options. The proposed 0-1 integer programming model has two objectives subject to fuzzy cash supply chain constraint conditions, and the escalating GA will be employed to solve the above optimization model with...
Basic ideas that providing explanation to the movement of information in information systems were proposed in the light of regarding information as a kind of matter. It was suggested that information had both "momentum" and "energy". The momentum of information provided explanation for the dynamic behaviors, and the energy of information provided explanation for the static attributes...
This paper presents a new stochastic chance-constrained 0-1 integer programming model for investigating the investment combination problem in multi-project multi-item investment combination. The proposed model includes two objectives with stochastic constraints to construct a 0-1 integer programming model. On the one hand, the risk value will be measured by negative entropy; on the other hand, the...
This paper aims to solve the multi-project multi-item investment combination under stochastic surroundings. A new stochastic chance-constrained programming model for investigating its problem will be presented, in which there are three objectives with some stochastic constraints to construct a 0-1 integer programming model, and demonstrate how to use PSO to solve the optimization model with a small...
