Recently, attention has been focused on provid­ ing Knowledge Acquisition (KA) support for building practical planning systems. Such sup­ port is needed to guide a knowledge engineer in selecting planning methods, as well as for build­ ing and validating the planning knowledge-base for a given practical domain. Following cur­ rent practice in knowledge acquisition, devel­ oping KA tools for pla...

Vibration is one of the most important resources of error in motion of tip of flexible robot manipulators. Although much work has been done in the design of controllers for flexible manipulators to follow a specified tip trajectory, it has been done a little work in trajectory planning itself. For redundant robot manipulators, trajectory planning can be accomplished with the aim of optimizing s...

Cooperative game is an approach for a group of decision-making agents (DMAs) to reach mutually beneficial agreements where the players make agreements in order to optimize their common cost or payment. A coordination mechanism is required to achieve a rational and structured plan for a decision jointly made by independent DMAs. This paper presents a cooperative game for the problem of collabora...

In project planning and control it is of vital importance to take into account that diierent categories of resources have diierent work patterns. Algorithms for time analysis, resource smoothing and resource scheduling are almost always presented as if this has no importance. Practical planning tools, however, have diierent work patterns as a natural part of the data. In this paper, we discuss ...

This doctoral work centers on developing domain-independent heuristics for planning problems characterized by state incompleteness and action non-determinism. The key means by which the heuristics are computed is through planning graph analysis. The approach has been used to construct conformant and contingent plans in two different search techniques. The initial focus of the research was inves...

In real-world applications of AI and automation such as in robotics, computer game playing and web-services, agents need to make decisions in unstructured environments that are open-world, dynamic and partially observable. In the AI and Robotics research communities in particular, there is much interest in equipping robots to operate with minimal human intervention in diverse scenarios such as ...

Information systems planning (ISP) work has changed tremendously during the last twenty years. Previously as a work of IT/IS professionals it has now changed towards a collaborative planning challenge of several stakeholders, such as top managers, business unit managers, IT/IS professionals and even external stakeholders such as customers, partners etc. In addition to that it is very often labe...
