In individual decision making experiments I test the robustness of biases in the perception of independence and whether they survive feedback about the median decision in groups of five. I argue that the median decision reflects the market clearing price in an equivalent interactive market setting. Despite better experimental control, known biases are confirmed but also qualified. While feedbac...

I describe a planning methodology for domains with uncertainty in the form of external events that are not completely predictable. Under certain conditions, these events can be modelled as continuous-time Markov chains whose states are characterised by the planner’s domain predicates. Planning is goal-directed, but the subgoals are suggested by analysing the utility of the partial plan rather t...

I present a straightforward objection to the view that what we know has epistemic probability 1: when combined with Bayesian decision theory, the view seems to entail implausible conclusions concerning rational choice. I consider and reject three responses. The first holds that the fault is with decision theory, rather than the view that knowledge has probability 1. The second two try to reconc...

In this paper I discuss the problem of providing an account of the normative force of theories of rationality. The theories considered are theories of rational inference, rational belief and rational decision— logic, probability theory and decision theory, respectively. I provide a naturalistic account of the normativity of these theories that is not viciously circular. The account offered does...

INTR()DUCTi()N Organizations vltry in the way they respond to orglmizational problems, even when they are in similar task environments or are facing simihu stress conditions (Scott 1987). This way of response is due, in part, agent style (Kets de Vries and Miller 1986; LaPorle and Consolini 1991), which is also related to the norms in, or culture of, thc organization (Parsons 1956; Blumberg 198...

The multiplicative hesitant fuzzy information proposed by Xia (2012) uses the non-uniform scale to express the preference of the decision makers which has a broad application background. The key difference between multiplicative hesitant fuzzy information and hesitant fuzzy information is the former uses unsymmetrical scale in expressing the preferences about two alternatives but the latter use...

this paper applies a new multi attribute decision-making (madm) model to help companies for enterprise resource planning (erp) selection problem based on balanced score card method. this paper uses three-parameter interval grey numbers which is derived from grey theory (was proposed by j. deng). this numbers is used instead of linguistic variables. beside, a new weighting method that outcomes f...

I show that virtually any model of decision making under uncertainty is associated to a certain structure. This contains three fundamental ingredients: (1) The domain of the acts; (2) Another set, which is called the set of models for the decision maker; and (3) The decision maker’s information about the set of models (an algebra of subsets of the set of models). A consequence of this finding i...
