International projects proposal analysis: Risk assessment using radial maps

International projects are very attractive to companies seeking to expand their business horizons, and collaborative networks of international partners have created new work environments that differ from the conventional business structures of the past. This study provides scholarly research into the risks that inherently affect an international project's success and provides insight into the effective measures that project managers may employ to assist in analyzing and mitigating these multinational risks during the bid and proposal process. A new method of radial risk mapping assists management in graphing their risk findings to aid in their proposal analysis. These graphical representations provide firms seeking international markets with a method for selecting those projects with the least risk, thereby increasing their chances of success and maximum profit.

Commercial Mortgage Default: A Comparison of Logit with Radial Basis Function Networks

This article explores the use of artificial neural networks in the modeling of foreclosure of commercial mortgages. The study employs a large set of individual loan histories previously used in the literature of proportional hazard models on loan default. Radial basis function networks are trained (estimated) using the same input variables as those used in the logistic. The objective is to demonstrate the use of networks in forecasting mortgage default and to compare their performance with that of the logistic benchmark in terms of prediction accuracy. Neural networks are shown to be superior to the logistic in terms of discriminating between good and bad loans. The study performs sensitivity analysis on the average loan and offers suggestions on further improving prediction of defaulting loans.
