In this paper, we discuss the relationship between multi-attribute utility theory and DEA models without explicit inputs (DEA-WEI), including dual models and some theoretical analysis of DEA-WEI models. We then propose generic DEA-WEI models with quadratic utility terms. Finally, we provide illustrative examples to show that DEA-WEI with suitable quadratic utility terms are able to reflect some...

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...

We are witnessing evolution of standards (as the functional safety one) and increasing of complexity. This implies to perform safety studies efficiently and earlier in the context of Model-Based System Engineering. So, in this article, we will propose an evolution of the Preliminary Hazard Analysis (PHA) method in order to comply with the overall safety requirements in the automotive domain. To...

background: cutaneous leishmaniasis (cl) is a parasitic disease with a relatively wide distribution in different areas of the world, including iran. the parasite is mainly diagnosed microscopically, but serological approaches might be useful for diagnosis as well.  this study aimed to assess the efficacy of an immunoblotting system for serodiagnosis of cutaneous leishmaniasis in iran. methods: ...

nowadays multicriteria decision making (mcdm) methods are a useful tool for investigating natural resources and toaddress problems related to hydro systems. the goal of this research was to assess the daliri standardization method(dsm) to prioritize and make selections for application to mcdm. and to compare the dsm method with the utilityadditive (uta) method. the (dsm) method, unlike the (uta...

In a competitive market, customer decision is made to maximize his utility. It can be assumed that risk of losing a supply chain’s customer can be defined based on products utility from customer point of view. This paper takes account of product price and service level as competition criteria. The proposed model is based on non-cooperative game theory, for one-manufacturer and one-retailer supp...

E-mail: [email protected] In statistical analyses the researcher should normally use all the relevant information in the data. This argument has been used to advise against the habit of dichotomizing (approximately) continuous variables. However, if, for instance, a continuous variable is not normally distributed, it is possible that an optimal dichotomization can reveal relationships betwee...

Recently, representations and methods aimed at analysing decision problems where probabilities and values (utilities) are associated with distributions over them (second-order representations) have been suggested. In this paper we present an approach to how imprecise information can be modelled by means of second-order distributions and how a risk evaluation process can be elaborated by integra...

This paper examines the lifetime portfolio-selection problem in the presence of transaction costs. Using a discrete time approach, we develop analytical expressions for the investor’s indirect utility function and also for the boundaries of the no-transactions region. The economy consists of a single risky asset and a riskless asset. Transactions in the risky asset incur proportional transactio...
