Computer generated battleeeld agents need to be able to explain the rationales for their actions. Such explanations make it easier to validate agent behavior, and can enhance the eeectiveness of the agents as training devices. This paper describes an explanation capability called Debrief that enables agents implemented in Soar to describe and justify their decisions. Debrief determines the moti...

It is shown that the model of twoor multistage programming undi^r risk results from the application of the principle of dynamic planning* in special structured dynamic decision situations under risk. By u ^ing this property, some characteristics of the solution set of dynamic planning problems will be derived. *This principle is well known and discussed as "flexible Planung" in the German manag...

The characteristics of wireless sensor networks are such that traditional approaches to network management and monitoring are inappropriate. In this paper a system for performance debugging in wireless sensor networks is presented. It tracks two key metrics the delay and reliability of message delivery. Its principle of operation is to reactively isolate and diagnose problems once they occur, r...

This paper discusses the impacts of resource tax reform on the optimal resources extraction in China when the time of resource tax reform and the ways of taxes levy are uncertain. Based on the assumption that the process for accepting resource tax reform follows Poisson process, we first divide resource extraction into two processes by using the idea of dynamic planning. We then apply the optim...

This paper describes the development and validation of a simulation model capable of simulating a submarine hunt using multi-sensor fusion of signals from passive sonobuoys and of computing a near-optimal placement for the next buoy to be deployed.

This effort investigated methods to provide superior decision support primarily for dynamic planning and execution in support of both Crisis Action Plans and Deliberate Planning. This was accomplished by evaluating current Air Force wargaming methods and looking at ways to improve them. Issues with current wargaming methods were identified while methods for improving them were developed, leadin...

We analyze optimal production and pricing strategies in the single period (newsvendor) dual sourcing problem that entails local and offshore suppliers. The local supplier is used reactively as an emergency source following the realization of random demand. A multiplicative demand model is employed. We show that dual sourcing flexibility may decrease optimal price when emergency supply cost is s...

Situated and embodied reactive agents solve relatively complex tasks by coordinating action and perception. Reactive agents are generally believed to be incapable of coping with identical sensory states that require different responses (i.e., perceptual ambiguity). In contrast to reactive agents, non-reactive agents can cope with perceptual ambiguity by storing and integrating sensory informati...

The objective of our research effort is to enable robots to engage in complex collaborative tasks with humanrobot interaction. To function as a reliable assistant or teammate, the robot must be able to adapt to the actions of its human partner and respond to temporal variations in its own and its partner’s actions. Dynamic plan execution algorithms provide a fast and robust method of executing ...

In this paper we present a novel planning approach, based on wellknown techniques such as goal decomposition and heuristic planning, aimed at working in highly dynamic environments with time constraints. Our contribution is a domain-independent planner to incrementally generate plans under a deliberative framework for reactive domains. The planner follows the anytime principles, i.e a first sol...
