Many factors innuence the performance of a learned classiier. In this paper we study diier-ent methods of measuring performance based on a uniied set of cost models and the eeects of training class distribution with respect to these models. Observations from these eeects help us devise a distributed multi-classiier meta-learning approach to learn in domains with skewed class distributions, non-...

This paper develops a framework for stress-testing the credit risk of Chinese commercial banks to macroeconomic shocks. Using data over the period 1985-2008, this study establishes a vector auto-regression (VAR) model to describe the links between default rate and macroeconomic factors, and then designs three stress scenarios to implement the stress testing by Monte Carlo simulation. As a resul...

This paper considers a two stages pharmaceutical supply chain (PSC) consisting of a pharmaceutical manufacturer (pharma-manufacturer) that supplies one type of pharmaceutical product to a pharma-retailer. The customer demand rate for the pharmaceutical product is dependent on the pharma-retailer’s current-inventory level. The pharma-retailer determines the order quantity ( ) value as decision v...

Supplier selection is one of the most critical activities of purchasing management in supply chain and managers increasingly face sourcing decisions of how to selected suppliers. This paper illustrates the development of a sourcing decision that provides support for the buyer firm in supply chain.The models developed here, involved selecting between single and dual sourcing. Outside and local s...

Many factors innuence a learning process and the performance of a learned classiier. In this paper we investigate the eeects of class distribution in the training set on performance. We also study diierent methods of measuring performance based on cost models and the performance eeects of training class distribution with respect to the diierent cost models. Observations from these eeects help u...
