We describe a way to improve the performance of MDP planners by modifying them to use lower and upper bounds to eliminate non-optimal actions during their search. First, we discuss a particular state-abstraction formulation of MDP planning problems and how to use that formulation to compute bounds on the Q-functions of those planning problems. Then, we describe how to incorporate those bounds i...

The main goal of our research is to establish “methodology for investigation of event” and to construct “a knowledge reconstruction system” to provide event planners with “chances” to design effective and attractive events. The methodology described here is to articulate gaps between event planners’ intention and event visitors’ mental impression at real event sites. Visitors’ interactions with...

Original scientific paper Nowadays the production process with as few as possible deadlocks is the most important goal of management in every company. An optimized production process can be reached with well-trained personnel and especially with well-trained schedule planners. In this contribution, a new strategy on how to train production planners for different types of production by using vir...

Recent advances in AI planning technology have drastically improved the capabilities of modern planners. However, these advances have left research in domain specialization behind; many older specialization techniques are no longer applicable to modern planners. This paper explores how to automate domain specialization in a modern planning as constraint satisfaction engine using existing analys...

Constructing a planner for a particular application is a diicult job, for which little concrete support is currently available. The literature on planning is overwhelming and there is no clear synthesis of the various planning methods which could be used by knowledge engineers. In this paper, we show how a general, knowledge-level framework for conceptually specifying knowledge-based systems, c...

In this paper, we present an analysis of planning with uncertain information regarding both the state of the world and the eeects of actions using a Strips-or (propositional) Adl-style representation 4, 17]. We provide formal deenitions of plans under incomplete information and conditional plans, and describe Plinth, a conditional linear planner based on these deenitions. We also clarify the de...

Rapidly increasing urbanization in the world, especially in developing countries, let to increasing urban extents. Rapid urban growth causes to appearance many problems such as wasting environmental resources, inability of providing necessary services for citizens and unplanned growth. Urban mangers and planners need tools for understanding amount and size of future urban growths to prevent the...

PLANNING IN ITS POLITICAL CONTEXT: Developing Organizational Strategies for the Planning Agency by Daniel Stephen Greenbaum Submitted to the Department of Urban Studies and Planning on August 9, 1974, in partial fulfillment of the requirements for the degree of Master of City Planning. Planners are trained to provide rational technical analysis of public policy issues to guide governmental acti...

This paper chronicles some issues that arose in attempting to implement two simple planners that interleave planning and execution. (For brevity, such planners will be called IPE planners.) The IPE planners are based on UCPOP (Barrett et al. 1993), a classic operator-based planner using goal-regression. Unfortunately, while the planners succeeded on very simple problems, they failed on problems...
