This paper presents a new approach to minimize the operation cost of wind-diesel system. Under the constraints of diesel units' startup/shut down time, ramp rate and power balance etc., the ‘Unit Commitment’ concept is introduced to construct the model for optimal operation planning of all...

This paper investigates the influence of information asymmetry on the cross-sectional variation of volume-return relation. We find that the dynamic volume-return relation within medium-size trades has the most significant response to the degree of information asymmetry. We also show that the...

This paper applies entropy weight and grey relation analysis to evaluate corporate social responsibility (CSR) performance of eight Chinese major airlines. This paper intends to achieve two main aims. First, this study uses entropy to find the relative weights of performance measures of CSR. In...
