Utility functions for ceteris paribus preferences
… ceteris paribus preferences into a quantitative utility function. Our algorithm is complete for a finite universe of binary features. Constructing the utility function can, in the worst case, take time exponential in the number of features. Common forms of independence conditions reduce the …

Multiattribute utility functions for the deep borehole filter restoration problem
… This dissertation studies multiattribute utility functions for modeling such challenging decision problems using the example of the deep borehole filter restoration problem from the uranium extraction industry. In this problem, the filter of the production borehole (or well) is …

Visualization impacts on utility functions and multiattribute utility copula approach toward electronic product recovery techniques
… can have on the environment. A multiattribute utility copula approach was used in analyzing the behavior of EOL processing activities on the part of an OEM. This decision-making tool was used in order to incorporate the firm’s preferences while accounting for uncertainty with the incoming …

Characterization and computation of equilibria in infinite games
… games (those with continuous strategy spaces and utility functions) with a view towards computation of equilibria. We cover all of the game-theoretic background needed to understand these results in detail. Then we present new work, which can be divided into three parts. First, it is known that …

Supermodular utility representations
… and invoke the assumption of supermodularity of utility functions. In the context of choice over finite lattices, it is well-known that existence of supermodular representations is equivalent to existence of quasisupermodular ones for monotone preferences. In particular, strictly monotone …

Utility Libraries for Traversing and Manipulating Tree-like Data Structures with Varying Schemas
… large-scale code bases having to implement their utility functions over and over again. To address these concerns within the JavaScript developer community, we propose Treecle and Vastly: two free open-source libraries that provide utility functions and operations to help developers work with …

Learning-NUM: Utility Maximization in Stochastic Queueing Networks
Network Utility Maximization (NUM) studies the problems of allocating traffic rates to network users in order to maximize the users’ total utility subject to network resource constraints. We propose a new paradigm of utility maximization in stochastic queueing networks where the utility functions …

Model complexity and risk aversion in decision analysis
… very well in a variety of settings. Although utility functions are a fundamental component of decision analysis, they can assume many forms. For small decisions, the choice might not change the decision. But it can greatly affect recommendations for large decisions. There are qualitative …

Behavioral decision theory and the negotiation process; effects of agenda and frame
… models of preference (Expected Value, Expected Utility, and Prospect Theory) by fitting utility functions to negotiation behavior observed in a laboratory setting. In addition to inferring the form of the utility function from observed negotiation behavior, utility functions were measured …

A Probabilistic Decision Support System for a Performance-Based Design of Infrastructures
… of such fundamental facilities should maximize utility for the designers, occupants, and the society. With respect to the nature of the decision problem, two main types of uncertainties may exist: 1) the aleatory uncertainty associated with the nature of the built environment (i.e., the …

Utility-Aware Scheduling of Stochastic Real-Time Systems
Time utility functions offer a reasonably general way to describe the complex timing constraints of real-time and cyber-physical systems. However, utility-aware scheduling policy design is an open research problem. In particular, scheduling policies that optimize expected utility accrual are needed …

Recovery of primal solution in dual subgradient schemes
… of the scheme in the framework of Network Utility Maximization (NUM), which has recently drawn great research interest. Specifically for the NUM problems, which can have concave or nonconcave utility functions and linear constraints, we apply the dual-based decentralized subgradient method …

Resource Allocation for Smart Phones in 4G LTE-Advanced Carrier Aggregation
… Frank Kelly algorithm that allows for the use of utility functions that are piecewise concave, but not a member of a strictly \'diminishing return\' model. This adjustment to the Frank Kelly algorithm allows resource allocation to take into account devices with multiple applications. The second …

Modeling dynamic community acceptance of mining using agent-based modeling
… This objective focuses on: 1) formulating agent utility functions for ABM, based on discrete choice theory; 2) applying ABM to account for the effect of information diffusion on community acceptance; and 3) explaining the relationship between initial conditions, topology, and rate of …

Modeling and analysis of affective influences on human experience, prediction, decision making, and behavior
… Prospect Theory (PT)- based subjective value functions to model human experienced-utility and predicted-utility functions. The AC model assumes that the shapes (or parameters) of these subjective value functions dynamically vary with the decision makers affective states in sequential decision …

Investor preferences in the securities options market
… We propose that when investors maximize expected utility for Friedman-Savage-Markowitz utility functions, the option mispricing observed in the market will result. The theories and empirical tests in the literature of higher-order utility functions and risk-neutral valuation (RNV) in the options …

Risk Aversion and Consumer Choice With Many Commodities
… towards risk affect the choices of expected utility maximizing agents whose preferences are defined over a single variable, wealth. The restriction of the analysis to utility functions of one argument, however, severely limits its applicability: in many problems of choice we must represent …

An investigation of the equity premium using habit utility and equity returns: Australian evidence
… investor has additive and separable utility functions in the perfect market. Compared to other forms or utility functions, at a certain period, these conventional preferences derived from utility of consumption in previous periods. Also this utility maintains a constance risk aversion …

Resource allocation in realistic wireless cognitive radios networks
