The analytic network processes method & fuzzy cognitive map method in decision making: a comparative study

s: Decision making problems always puzzled managers and decision makers in enterprises or organizations. There are many useful soft operation research methods could solve the complicated problem. The paper raises two classic approaches ANP (Analytical network process) and FCM (Fuzzy cognitive map). Those two methods have some similarities and differences. In thus, according to different decisio...

Large engineering project risk management using a Bayesian belief network

This paper presents a scheme for large engineering project risk management using a Bayesian belief network and applies it to the Korean shipbuilding industry. Twenty-six different risks were deduced from expert interviews and a literature review. A survey analysis was conducted on 252 experts from 11 major Korean shipbuilding companies in April 2007. The overall major risks were design change, ...

Bayesian causal phenotype network incorporating genetic variation and biological knowledge

A Bayesian network has often been modeled to infer a gene regulatory network from expression data. Genotypes along with gene expression can further reveal the regulatory relations and genetic architectures. Biological knowledge can also be incorporated to improve the reconstruction of a gene network. In this work, we propose a Bayesian framework to jointly infer a gene network and weights of pr...
