In the multi-attribute utility theory the utility functions are usually constructed by dots. It concerns both the lottery’s method and the value increasing method. In the both cases the utility function is constructed in the absolute scale [0,1] that causes inconveniences for experts. The comparative assessments look more preferable for decision-makers. The paired comparison matrix (PCM) looks ...

OBJECTIVE We aimed to assess the effects of age, comorbidity, and disease-specific functions on utility scores derived from three methods on prostate cancer. METHODS A total of 330 Japanese prostate cancer patients were asked to answer self-administered questionnaires. Community-weighted utility scores were derived from the EuroQoL-5D (EQ-5D) and the Short Form-36 (SF-36), while the patient's...

This work concerns decision making under risk with the rank-dependent utility model (RDU), a generalization of expected utility providing enhanced descriptive possibilities. We introduce a new incremental decision procedure, involving monotone regression spline functions to model both components of RDU, namely the probability weighting function and the utility function. First, assuming the util...

the purpose of this paper is to analyze the utility operating radius and service on city parks in ardabil neighborhood, local, regional and urban level, to investigate the relationship between the distribution of these parks with water levels in the city of ardabil, including shorabil lake and balyqlv river and reviews for distribution park. the data and information used by documentary. to anal...

In his so-called 'Allais Impossibility Theorem', Allais (1988) asserts that the technique of 'generalized expected utility analysis' from Machina (1982) is invalid, on the grounds that its key tool, the 'local utility function', cannot be well-defined for preferences over finite-outcome lotteries. This paper presents a brief description of the local utility function and a summary of Allais' arg...

A bstract We define the utility of the specified up state of the system, 2: Xi, consisting of n independent multistate items. A measure of importance of an item and that of a given state of an item are discussed with respect to the expected utility function. It is shown that., for non-decreasing utility functions, the perfect state of an item yields maximum contribution to the expected utility ...

The purpose of the present paper is to introduce a methodology, using structural equation modeling, that we believe has the potential to improve the design of assistive technology products. In addition, a large-scale evaluation of the methodology is currently underway (to be completed in early 2011) that focuses on power wheelchair use and users. The methodology attempts to determine the future...

In this research, firms aim at maximizing two purposes of social welfare (environment) and profitability in the supply chain system. It is assumed that there are two supply chains, a green and an ordinary, each consists of a manufacturer and a supplier; in which the manufacturer generates profit through franchises. The green and the ordinary manufacturers form a cartel on the market of a certai...

In order to seek a new method of book evaluation and realize book resources sharing among the regional university libraries, we think that library should collect books of the high utility value in the case of limited funds. We proposed a changing Bellman equation as a utility function and used the explicit functions of the book usage factor and the book usage half-life derived from the utility ...
