This paper constructs the knowledge transfer simulation mode based on small world network model. It uses the average path length and clustering coefficient to stand for AC frequency and aggregation degree among knowledge network nodes and studies the node’s ability to release and absorb as well as the knowledge transfer effect by trust degree. Simulation results show that improving the AC frequency and aggregation degree of nodes, enhancing node’s ability to transfer knowledge can ensure transfer frequency in organization reaching a high level.

The resource-constrained project scheduling problem (RCPSP) includes activities which have to be scheduled due to precedence and resource restrictions such that an objective is satisfied. There are several variants of this problem currently, and also different objectives are considered with regards to the specific applications. This paper tries to introduce a new multiagent learning algorithm (MALA) for solving the multi-mode resource-constrained project scheduling problem (MMRCPSP), in which the activities of the project can be performed in multiple execution modes. This work aims to minimize the total project duration which is referred to its makespan. The experimental results show that our method is a new one for this specific problem and can outperform other algorithms in different areas.

In this paper, the consensus problem of second-order nonlinear multi-agent systems with directed communication topology is discussed. Information for the states of neighbour agents is quantized using a uniform quantizer. The sliding mode control law is designed based on quantized state information and the stability analyzed by using Lyapunov theory. Additionally, an iterative learning control law based on sliding mode errors is developed. Thereby, a novel consensus control protocol consisting of a sliding mode control law and an iterative learning approach is achieved, where the purpose of applying the sliding mode control law is to eliminate non-repeatable uncertainties and the iterative learning control law is to remove repeatable disturbances. Also, the convergence of the proposed control protocol is analyzed in the frequency domain. Finally, two cases are provided to illustrate the effectiveness of theoretical analysis.

자동화된 건강관리 모니터링은 많은 시간이 소요되고, 많은 문제들이 발생할 수 있다. 왜냐하면 정시에 환자들의 건강 상태에 대한 모니터링 정보를 제공받기 어렵기 때문이다 이 논문에서는 임베디드된 건강 관리 서비스가 iSCSI 프로토콜에 의해 제안된다. 이 프로토콜은 자동화된 멀티에이전트와 제한된 자원의 디바이스들(예. PD4 스마트폰, 테블릿PC)의 협력체계에 기반을 두고 있다. 이 둘의 협력체계는 쌍방향 iSCSI 프로토콜에 의해 유지된다. 자동화된 건강관리 제어는 반복되는 방식에서 매우 유용할 수 있다. 완전 집중화된 제어에서는 이 방법이 적용될 수 없다.

An automated healthcare monitoring is demand of time, lot of problems occurring just because of less monitoring of patients health condition on time. In this paper an embedded healthcare service is proposed by an iSCSI protocol on an automated multi-agent coordination by resource-constrained devices controlled system for healthcare service. The coordination between the resource constrained devices (e.g. PDA, SmartPhone, Tablet PC), and automated agents are maintained by a two-way handshaking mode iSCSI protocol. The automated health care control could be useable, and beneficial in the repetitive way. A fully centralized control is not applicable for this kind of approach.

In this paper, we present a finite-time sliding mode control (FSMC) with an integral finite-time sliding surface for applying the concept of graph theory to a distributed wheeled mobile robot (WMR) system. The kinematic and dynamic property of the WMR system are considered simultaneously to design a finite-time sliding mode controller. Next, consensus and formation control laws for distributed WMR systems are derived by using the graph theory. The kinematic and dynamic controllers are applied simultaneously to compensate the dynamic effect of the WMR system. Compared to the conventional sliding mode control (SMC), fast convergence is assured and the finite-time performance index is derived using extended Lyapunov function with adaptive law to describe the uncertainty. Numerical simulation results of formation control for WMR systems shows the efficacy of the proposed controller.
