  • In this study, classification and regression trees (CART) and adaptive neuro-fuzzy inference systems (ANFIS) will be developed as an effective intelligent system for performing machine fault diagnosis and condition prognosis. CART is known as one of the illustrious techniques of the decision tree induction and used for the purpose of either classification or regression depending on the output variable which is categorical or numerical. CART recursively partitions the entire data into binary descendant subsets which are as homogeneous as possible with respect to the response variables. High effective omputation and reliability are the remarkable advantages of this algorithm. In the sec...

  • The major objective of this research is to describe how the BSC and trength-Weakness-Opportunity -Thread (SWOT) matrix can be used to formulate the business strategies and to measure the strategic performance of construction. Angiang Construction Enterprise (ACE) is selected as a case study to measure the strategic performance. An applicable simulation model of a construction enterprise was built using system dynamics methodology. The DBSC model was calibrated to a construction enterprise to measure the strategic performance and to formulate and evaluate practical policies to improve its performance. In order to considerably improve performance, some integrated policies combining the ...
