Investments in generation capacity in restructured electricity systems remain a relatively unexplored subject in the modeling community. We consider three models that differ by their underlying economic assumptions and the degree to which they depart from the old capacity expansion...

With the release of Stata 7, the glm command for fitting generalized linear models underwent a substantial overhaul. Stata 7 glm contains an expanded array of variance estimators, regression diagnostics, and other enhancements. The overhaul took place to coincide with the release of Hardin and...

A dual problem for convex generalized fractional programs with no duality gap is presented and it is shown how this dual program can be efficiently solved using a parametric approach. The resulting algorithm can be seen as "dual" to the Dinkelbach-type algorithm for generalized fractional...

In this paper, we present a heuristic procedure based on tabu search (TS) and intelligent memory structures for solving this problem. The TS method starts with a feasible schedule generated by a greedy forward dispatching procedure, then through a series of intensification and diversification...

Audit scheduling with overlapping activities and sequence dependent setup cost has not been treated in literature. This paper presents a formulation and a solution approach for this audit scheduling problem. In this paper, we treat the activity duration as a decision variable and include...

The homogeneous search equilibrium model of Mortensen (1990) and Burdett and Mortensen (1998) is extended to allow on-the-job wage growth. The extension allows an improved empirical fit to the cross-section wage distribution. The estimation problem is nonregular but tractable. Estimated...

With this study we intend to define a methodology capable to deal with the task of evaluating and planning the interdependent dynamics of growth for some European countries together with their foreign partners. To that aim we employ a nonlinear differential equations system representing a...

In this paper we review the current state of the problem solving environment (PSE) field and make projections for the future. First we describe the computing context, the definition of a PSE and the goals of a PSE. The state-of-the-art is summarized along with the principal components and...
