the present study aim is to offer a systematic method of assessing the credit risk of banks and also to identify key indicators using decision making trial and evaluation laboratory (dematel) technique as well as using logit regression in order to predict the credit risk of listed banks. the population of the study consists of the legal clients of the bank (ansar bank, bank saderat iran, bank m...

capacity of garden productions in iran is such that is accounted as a country that produces thirteen garden products in the world but despite excellent condition in iran for producing garden products, natural disasters damage production of fruits in the country therefore farmers incur a loss. pistachio tree has been in danger of destruction and dryness. thus, in order to reduce loss incurred on...

We introduce a Generalized Nested Logit model of demand for bundles that can be estimated sequentially and virtually eliminates any challenge dimensionality related to large choice sets. use it investigate quantity discounts carbonated soft drinks by simulating counterfactual with linear pricing. The prices quantities up 1L decrease −31.5% while those larger increase +14.8%. Purchased −20.4%, a...

In this paper we empirically analyse two counterfactual situations facing an anti-trust authority following the merger of two of the largest international cigarette companies. First we estimate a nested logit model of demand for cigarettes. The implied elasticity of demand for smoking and implied marginal costs are both broadly consistent with the limited independent estimates available. We the...

one of the farmers' marketing decisions is how to sell their products to the market. they sell their products in different ways, for example pre-sell, local dealers and wholesalers,. this paper aims at investigating citrus distribution channels and evaluation of factors affecting the choice of each channels by mazandaran ‘s producers. the data was collected by simple random sampling method. 252...

This study provides a gradient projection (GP) algorithm to solve the combined modal split and traffic assignment (CMSTA) problem. The nested logit (NL) model is used consider mode correlation under user equilibrium (UE) route choice condition. Specifically, two-phase GP developed handle hierarchical structure of NL in CMSTA Seoul transportation network Korea adopted demonstrate an applicabilit...

Understanding the underlying relationship between crash injury severity and factors such as driver’s characteristics, vehicle type, and roadway conditions is very important for improving traffic safety. Most previous studies on this topic used traditional statistical models such as ordered probit OP , multinomial logit, and nested logit models. This research introduces the Bayesian inference an...

The choice network revenue management model incorporates customer purchase behavior as a function of the offered products, and is the appropriate model for airline and hotel network revenue management, dynamic sales of bundles, and dynamic assortment optimization. The optimization problem is a stochastic dynamic program and is intractable. A certainty-equivalence relaxation of the dynamic progr...
