This paper describes the need to view a planner as situated in an environment dealing with the whole planning problem While a planning agent deals with plan generation aspects other agents are concerned with aspects such as task elicitation plan analysis reactive execution plan repair etc Each of these systems has its own perspective on the planning problem and each of the systems must be capab...

This paper makes two linked contributions. First, we argue that p]ann;ng systems, instead of being correct (every plan returned achieves the goal) and complete (all such plans are returned), should be app~zimately correct and complete, in that most plans returned achieve the goal and that most such plans are returned. Our first contribution is to formalize this notion. Our second aim is to demo...

We consider plan execution for an autonomous robot to be a computational process that performs the following task: given (1) a plan that has been designed accomplish some jobs, (2) a stream of sensory data, and (3) a stream of feedback signals from the robot control processes, cause the robot to exhibit a behavior that accomplishes its jobs as specified by the plan. Plan execution would be triv...

in all over the world, mining is considered as a high-risk activity that is pregnant with serious disasters not only for miners, engineers, and other people into it, but also for people who live near the mines. in this article, our main purpose is to examine some major mine disasters and safety in mines and the case study is a coal mine in turkey. safety in mines is one of the most important is...

Most planning formalisms allow instances with shortest plans of exponential length. While such instances are problematic, they are usually unavoidable and can occur in practice. There are several known cases of restricted planning problems where plans can be exponential but always have a compact (ie. polynomial) representation, often using recursive macros. Such compact representations are impo...

There is increasing interest in using agents in open systems, such as the Agentcities1 project. It is obviously important for agents to interact with each other. These interactions are usually governed by interaction protocols that define the legal sequences of messages in a conversation. These interaction protocols need to be common to agents and are therefore usually defined by standards bodi...

Warnings are widely and commonly used in our lives. People almost unconsciously utter warnings, but the process of generating them has not been explained clearly. In this paper, we present a method of automatic warning generation from plan spaces. The type of warning dealt in this paper is confined as eliminatory warnings, which has a role of excluding other plans in the user’s plan space. The ...
