Social networking services (SNS) have had a rapid development. To explore the interpersonal node spatial distribution characteristics in SNS community, a fuzzy SNS community centrality analysis method is proposed, which combines graph-theory with related fuzzy approaches. A case study on two types of topic groups in Ren Ren Net is conducted. The study finds that centralization characteristics exist in the interpersonal node spatial distribution in SNS community and present significant difference among groups of different relation types. The findings can directly support the SNS management and development.

Risk assessment is one of the most important skills that pilots are expected to acquire to ensure the safe and successful management of flight. The traditional approach to the development of these skills requires pilots to directly engage with potentially hazardous events. This paper develops dual adaptive neuro-fuzzy inference system (D-ANFIS) in civil aviation as context for pilot's risk assessment, which can help reduce the risk to the aircraft aviation flight, while maintaining operational performance. It was concluded that exposure to hazards within a simulated environment could provide the basis for the development of risk assessment skills amongst less experienced pilots.

Environmental quality plays a very important role in the human survival and development, and therefore environmental quality assessment must be effectively carried out. The paper presents an adjustment regional environmental quality assessment based on differences of group bearing capacity, the strategy will help people to distinguish environmental quality real impacts on people and help people pay attention to and protect environment quality.

The theory of filters and fuzzy filters in logical algebras play a vital role in reasoning mechanism in informationsciences, computersciences, theory of control, artificial intelligence and many other important fields. We introduce the concept of fuzzy sub positive implicative filters of residuated lattice and investigate the properties of it, and further characterize the fuzzy sub positive implicative filters by proposing the equivalent conditions that a fuzzy filters to be a fuzzy sub positive implicative filters.
The technical term "lattice computing" was recently coined to refer to an evolving collection of tools and mathematical models for processing lattice ordered data such as numbers, intervals, possibility and ...

This paper discusses the partial r-interdiction median problem for multi-sourcing supply systems (PRIM-MS). Compared with r-interdiction median problem (RIM), PRIM-MS mainly has three characteristics: (1) Limited capacity for each facility;(2) Partial interdiction;(3) Multi-sourcing property for supply systems. PRIM-MS falls into bilevel programming in the form of leader-follower decisions, where the attacker tries to degrade system performance the most by determining offensive resources invested while the user rebuilds supply-demand relationship to reduce the influences by interdiction. In this paper, we model the problem as a single level heuristic model based on two heuristic strategies. Experiments are carried out to testify the effectiveness of the heuristic model.

Traditional tobacco intelligent sensory evaluation has no high accuracy due to the limitation of chemical components detection technologies. A new approach discussed in this paper utilizes the near-infrared spectroscopy (NIRS) to build the model of sensory quality instead of the analysis of chemical compositions. The results indicate that the NIRS models have greater ability to treat complex tobacco sensory analysis. The NIRS sensory evaluation which is fast, efficient and environmentally-friendly will become more prosperous in this field.

alpha-resolution principle based on lattice-valued logic is focused on in this paper, which is a great extension of resolution principle based on classical logic. Concretely, based on a Group resolution principle in lattice-valued logic, alpha-Group lock resolution principle is introduced, aiming to improve the efficiency of resolution and the ability of resolution. Then both the soundness and the completeness theorems of alpha-Group lock resolution principle are proved in lattice-valued propositional logic LICE). The example given in lattice-valued propositional logic LP(X) illustrates that alpha-Group lock resolution method is, to some extent, more resolution efficiency than alpha-Group resolution method and more resolution ability than alpha-lock resolution method, which only pemiits binary resolution in lattice-valued logic. This work will provide theoretical foundations for the establishment of automated reasoning algorithm and the further applications of automated reasoning and decision making under uncertainty.

Rough set is an useful tool to characterize uncertain information. It has been widely applied to feature selection. In this paper, we extend the information entropy into the kernel fuzzy rough set. Then, we construct the fast feature selection algorithm based on conditional entropy. Experimental results show that the conditional entropy-based feature selection algorithm can improve the classification performance with few features in most of the cases.
