This study reports an intensive, exploratory study of a single, protracted conflictual interaction involving all four members of a family. Within the larger interaction, there were four subinteractions. Because of space limitations, only the central conflictual subinteraction will be described. This interaction involved three of the four family members: the father and two daughters. The two chi...

We present a prototype of a decision sup­ port system for management of the fungal disease powdery mildew in winter wheat. The prototype is based on an influence di­ agram which is used to determine the op­ timal time and dose of mildew treatments. This involves multiple decision opportunities over time, stochasticity, inaccurate informa­ tion and incomplete knowledge. The paper describes the p...

Second-order calculations may significantly increase a decision maker’s understanding of a decision situation when handling aggregations of imprecise representations, as is the case in decision trees or influence diagrams, while the use of only first-order results gives an incomplete picture. The results apply also to approaches which do not explicitly deal with second-order distributions, inst...

This article introduces the idea that probabilistic reasoning (PR) may be understood as information compression by multiple alignment, unification and search (ICMAUS). In this context, multiple alignment has a meaning which is similar to but distinct from its meaning in bioinformatics, while unification means a simple merging of matching patterns, a meaning which is related to but simpler than ...

We derive qualitative relationships about the informational relevance of variables in graph­ ical decision models based on a considera­ tion of the topology of the models. Specifi­ cally, we identify dominance relations for the expected value of information on chance vari­ ables in terms of their position and relation­ ships in influence diagrams. The qualitative relationships can be harnessed ...

This paper proposes a partial implementation of an integrated Quality, Security and Environment management system [1] to deal with the definition of an appropriate global management plan. This implementation is based on the multi-objective influence diagrams [12] which are one of the most commonly used graphical decision models for reasoning under uncertainty with multiple objectives.

due to substantial effect of classification of resource models on future mine planning, one should come with an accurate method of estimation to guarantee that the minimum error is acquired in the estimation process. the known world class cu-mo deposit, sarcheshmeh porphyry deposit (central iran) selected as the study area. the hypogene zone of the deposit was chosen as the space in which estim...

the runoff generation and soil erosion in the kechik watershed, golestan province, was assessed, using a designed and constructed portable rainfall simulator. treatments were applied on different land-uses, slopes and aspects as the most influential factors. results showed that land-use significantly affected runoff generation (13.35 l, 6.9 l, and 4.12 l, respectively for agriculture, forest an...

The aim of the article is to show a stochastic approach for both modelling and optimizing the statistical agent belief in a probability model. Two networks are defined: a decision network D of the agent belief state and a utility network U, presenting the utility structure of the agent belief problem. The agent belief is presented via the following three items (B,D,U), where B is a Bayesian net...
