Utility-uncertainty Trade-off Structures*

چکیده
A qualitative axiomatization of a generalization of expected utility theory is given in which the expected value of simple gambles is not necessarily the product of subjective probability and utility. Representation and uniqueness theorems for these generalized structures are derived for both Archimedean and nonarchimedean cases. It is also shown that a simple condition called distributivity is necessary and sufficient in the case of simple gambles for one of these generalized expected utility structures to have simultaneously an additive subjective probability function and a multiplicative combining rule for expected values.

Choosing the Optimum Underground Mine Layout with Regard to Metal Price Uncertainty Using Expected Utility Theory
Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...
متن کاملStochastic Congestion Alleviation with a Trade-off between Demand Response Resources and Load Shedding
Under the smart grid environments, Demand Response Resources (DRRs) as power system resources can effectively participate in and improve performance of electric systems. Congestion management is one of the technical challenges in which DRRs can play a significant role. Previously, congestion management is applied without considering the power system uncertainties. Therefore, a stochastic conges...
متن کاملUncertainty trade-off and disturbance trade-off for quantum measurements
An important non-classical feature of quantum measurements is the celebrated uncertainty trade-off, namely that the uncertainties in the outcomes of measurements performed on distinct yet identically prepared ensembles of systems cannot all be made arbitrarily small. Recently, we have shown that quantum measurements also exhibit another non-classical feature of disturbance trade-off namely, tha...
متن کاملA Utility-based Multi-copy Forwarding Algorithm in Delay Tolerant Networks
In delay tolerant networks (DTNs) with uncertainty in node mobility, message forwarding usually employs a multi-copy, opportunistic forwarding scheme to improve delivery probability. Minimizing the delivery latency (delay) and minimizing the number of forwardings (message copies) have been two conflicting goals. On the other hand, utility-based routing has been proposed in multi-hop wireless ne...
متن کاملOpportunistic Branched Plans to Maximise Utility in the Presence of Resource Uncertainty
In many applications, especially autonomous exploration, there is a trade-off between operational safety, forcing conservatism about resource usage; and maximising utility, requiring high resource utilisation. In this paper we consider a method of generating plans that maintain this conservatism whilst allowing exploitation of situations where resource usage is better than pessimistically estim...
