Increasing attention has been focused on the analysis of the realized volatility, which can be treated as a proxy for the true volatility. In this paper, we study the potential use of the realized volatility as a proxy in a stochastic volatility model estimation. We estimate the leveraged...

An uncertainty set is a crucial component in robust optimization. Unfortunately, it is often unclear how to specify it precisely. Thus it is important to study sensitivity of the robust solution to variations in the uncertainty set, and to develop a method which improves stability of the robust...

The process of the evolution trajectory of the management logistics function is tracked in the context of the theory and practice of a networked approach to supply chain management (SCM). Issues around the main competitive forces are driving reforms in deregulation, globalisation, and...
