HTN planning paradigm has been widely used during the last decade to model and solve planning and scheduling problems. Even so, little research have been oriented to represent and generate these planning domains automatically with the help of software tools. In this paper we present an extensible software framework directed to cover this goal, proposing an(More)
Manufacturing systems are entering a new age in which the demands of a market in continuous change impose their conditions on production processes. In this new generation, both the response capability to these demands and a reliable production process are aspects that are receiving most attention and study. One of the stages that can most a!ect these terms(More)
This paper describes a preliminary work on Machine , a temporal partial order planner based on the use of temporal constraint networks to represent and propagate temporal constraints over the actions of a plan. The use of this formalism provide several advantages like the possibility of including deadline goals, makespans and imprecise temporal references(More)
Starting from a set of requirements which should be accomplished by any hierarchical planning approach to real-world problem solving, we show how known hierarchical models may be improved by means of a hybrid approach. Additionally, on the basis of this hybrid model, which is being applied to a real domain, we present a compared criticism about known(More)
In this paper we analyze the lessons learned during three projects that are being developed between our research group and our spin-off IActive Intelligent Solutions. These projects are based on the deployment of AI planning technology in three different business environments with a different degree of maturity in ICT. In these three cases we will focus on(More)
lal Ib~ (c~ Fig. 6. Applying the 4-block heuristics for three-dimensional pallet loading. (a) Layer 1; (b) Layer 2; (c) Layer 3. In this paper the problem of calculating optimal packing patterns of small rectangles on a pallet is considered. We propose new heuristics which are based on the 4-block structure of packing patterns. Since, in general, for(More)
The measurement of per capita daily expenditures relative to a monetary poverty line, also know n as ‘sophisticated means testing’, is the most w idely used approach to poverty assessment. H ow ever, it is reliant on the implementation of timeand cost-intensive household surveys. H ence, for operational purposes, it is not an effective method for targeting(More)
This work presents a translation process from a standard representation of plans into a standard executable format for Business Process Management (BPM). This translation is conceived as a Knowledge Engineering for Planning process that bridges the existing gap between AI Planning and Busines Process Management and provides support for the direct execution(More)
This work introduces SIADEX 1, a planning framework intented to assist human experts in the design of forest fire fighting plans. Issues about how to engineer planning knowledge for such a system, how to monitor the execution of fighting plans and how to patch unfeasible plans are discussed in detail.
