This paper proposes a stochastic user equilibrium assignment model for congested transit networks, together with a solution algorithm. A mathematical programming problem is formulated, that is equivalent to the stochastic user equilibrium assignment model for congested transit system. When the...

There are two difficulties in doing an objective evaluation of the performance of decision-making units (DMUs). The first one is how to treat undesirable outputs jointly produced with the desirable outputs, and the second one is how to treat uncontrollable variables, which often capture the...

In China, many ongoing problems in the electricity sector can be traced back to the old ‘centrally planned’ economy. Since the start of liberalization in the 1980s, the clash between a liberalized economy (excluding a few so-called strategic industries) and a centrally controlled electricity...

Incident energy on solar modules is lost both through reflection at the first air/glass interface of the packaging glass and through scattering or absorption by accumulated dust on outdoor panels. While simple antireflective coatings on the glass can help alleviate reflection in systems with...

The continuous network design problem (CNDP) is characterized by a bilevel programming model and recognized to be one of the most difficult and challenging problems in transportation. The main difficulty stems from the fact that the bilevel formulation for the CNDP is nonconvex and...

In this article we examine the effects of undesirable outputs on the Malmquist TFP indices. Our empirical work uses an unbalanced panel which covers 796 utility and non-utility coal-fired power plants in China during 1996-2002. In order to meet the requirement of a balanced panel for calculating...
