The composition of Web Services has been a topic of vital interest for supporting the tasks of both electronic commerce and the integration of applications among different firms by means of the web. The aim of this paper is to present an analysis about how the planning techniques in Artificial Intelligence can be used to carry out the composition of web services. This paper describes the main s...

Exploratory data analysis (EDA) is as much a matter of strategy as of selecting speci c statistical operations. We have developed a knowledge-based planning system, called Aide, to help users with EDA. Aide strikes a balance between conventional statistical packages, which need guidance for every step in the exploration, and autonomous systems, which leave the user entirely out of the decision-...

In the development of the IPC, there is an ongoing conflict between pushing the frontiers, and consolidating our technology. With growing PDDL, it becomes ever more difficult to achieve both. We propose to introduce a separate instrument for consolidation. A “tough nut” is a domain that can be addressed, language-wise, by existing planning techniques, but that cannot be solved efficiently. In a...

In free-floating mode, space manipulator systems have their thrusters off, and exhibit nonholonomic behavior due to angular momentum conservation. The system is underactuated and a challenging problem is to control both the end effector location and the base attitude, using manipulator actuators only. Here, a path planning methodology satisfying this double goal is presented. The key idea is to...

This paper explores the issue of planning in two-person games using approximately learned knowledge which is in the form of macros. A planning technique called Knowledge Enabled Planning, which consists of generating new plans by instantiating and composing the macros and testing them against the opponent's counter-plans, is introduced using a program called LEBL that learns and plans in two-pe...

Abstract Enterprise resource planning systems, if implemented successfully, can bestow impressive strategic, operational and information-related benefits to adopting firms. A failed implementation can often spell financial doom. Currently, most of the information about the failures and successes are based on reports on implementations in large manufacturing and service organizations. But enterp...

his paper deals with visual servoing for 6-degree-of-freedom root manipulators, and considers the problem of establishing hether and how it is possible to reach the desired location while eeping all features in the field of view and following a straight ine in the Euclidean space. A path-planning technique based on a arametrization of the camera path through polynomials is proosed, which overco...

This paper reports on our current eeort for applying probabilistic path planning techniques to logistics and operation in huge industrial installations (e.g., power plants). We show how the speciic domain constraints impose a dedicated software architecture to take advantage of the generality of probabilistic approaches. In addition, such an architecture should be compatible with existing CAD s...

Kinodynamic motion planning of an autonomous robot in an unknown or partially known indoor or outdoor environment is a challenging task, especially when the generated path must maintain the largest distance from surrounding obstacles and the robot’s kinodynamic properties, its localisation, and uncertainty of the environment are also considered. A new motion planning technique, which is built o...

In this paper, we describe situation calculus with aspect, which is an extension of the classical situation calculus. The new approach allows eecient representation of the frame axioms and partially ordered plans. In S.C. with aspect, uents and actions are associated with aspects. The frame axioms are replaced by axioms that describe the interference relation between aspects. A plan is represen...
