tion for Plannin Under Uncertainty
نویسنده
چکیده
The virtue of the STRIPS assumption for planning is that it bounds the information relevant to determining the effects of actions. Viewing the “assumption” as a statement about beliefs, we find that it does not actually assume anything about the world itself. We can characterize the assertion about beliefs in terms of probabilistic independence, thereby facilitating analysis of representations for planning under uncertainty. This interpretation separates the STRIPS assumption from other necessary features of a planning architecture, such as its model of persistence and its inferential policies. By isolating these factors, we can understand the role of dependence across a wide range of planners and action represent ations. Graphical models of dependence developed for probabilistic analysis provide a convenient tool for verifying the STRIPS assumption for a variety of planning systems. Investigation of a few representative systems reveals a Markovian event structure common to these planning models. The Frame Problem and the STRIPS

متن کاملA Nadir Compromise Programming for Supplier Selection Problem under Uncertainty
Supplier selection is one of the influential decisions for effectiveness of purchasing and manufacturing policies under competitive conditions of the market. Regarding the fact that decision makers (DMs) consider conflicting criteria for selecting suppliers, multiple-criteria programming is a promising approach to solve the problem. This paper develops a nadir compromise programming (NCP) model...

Core equivalence for economy under rough sets information
We reconsider the core equivalence theorem for a pure exchange economy under uncertainty from a rough set theoretical point of view in data mining; the traders are assumed to have a multi-modal logic of belief and to make their decision under uncertainty represented by rough sets. We propose a generalized notion of rational expectations equilibrium, called expecta,tion equilibrium in belief for...
