Stochastic game theory is proposed to apply in the research on network security situational awareness (NSSA), which is a research focus in network security field at present. A novel dynamic awareness method of network security situation (NSS) based on analyses of network service states is proposed in this paper. Realizing situation awareness is a dynamic process, and the diverse states of network services are just direct mirrors of the whole network security situation. Network security situation reflects what is happening in the network, including both the offense and defense behaviors in it. Stochastic game model of network security system is constructed in this paper, and network security situation is quantified by the game mathematical formulation, costs or rewards of attackers and defenders are established, and finally non-linear programming is used to compute the Nash equilibrium points, at which point both of the two sides get a balance between their benefits. Network security situation can then be dynamically achieved by visualizing the diverse metrics information of network services at Nash equilibrium during the operating of network system.

A critical problem in the deployment of commercial teleoperated robots is the development of effective training tools and methodologies. This paper describes our approach to the problem of providing such training to robot operators tasked to contaminated environments. The Vanguard MK2 and C2SMFast Sensor Simulator - a virtual reality based training system - provides an accurate simulation of the C2SM Crime Scene Modeler, an autonomous robotic system developed for the investigation of contaminated crime scenes. The training system provides a simulation of the underlying robotic platform and the C2SMFast sensor suite, and allows training on the system without physically deploying the robot or CBRNE contaminants. Here we describe the basic structure of the simulator and the software components that were used to construct it.

We propose an approach for finding an optimal path in a flexible jobshop manufacturing system considering two criteria of time and cost. With rise in demands, advancement in technology, and increase in production capacity, the need for more shops persists. Therefore, a flexible jobshop system has more than one shop with the same duty. The difference among shops with the same duty is in their machines with various specifications. A network is configured in which the nodes are considered to be the shops with arcs representing the paths among the shops. An Automated Guided Vehicle (AGV) functions as a material handling device through the manufacturing network. To account for uncertainty, we consider time to be a triangular fuzzy number and apply an expert system to infer cost. The objective is to find a path minimizing both the time and cost criteria, aggregately. Since time and cost have different scales, a normalization procedure is proposed to remove the scales. The model being bi-objective, the AHP weighing method is applied to construct a single objective. Finally, a dynamic programming approach is presented for computing a shortest path in the network. The effectiveness of the proposed approach is illustrated by a numerical example.
