Indifference-zone-selection procedures have been widely studied and applied to determine the required sample sizes for selecting a good design from k alternatives. However, efficiency is still a key concern for application of simulation to ranking and selection problems. In this paper, we present a new approach that can further enhance the efficiency of indifferencezone-selection procedures. Ou...

The Loanable funds theory Hypotheses: Individuals care only about real variables (output gains or losses, purchasing-power gains or losses). The marginal productivity of capital assets (MPK) is given and determined by the technical characteristics of the productive assets. It represents the gain, in terms of output, obtained by increasing the capacity of production by one additional capital ass...

Toluene photooxidation is chosen as an example to examine how simulations of smog-chamber experiments can be used to unravel shortcomings in detailed mechanisms and to provide information on complex reaction systems that will be crucial for the design of future validation experiments. The mechanism used in this study is extracted from the Master Chemical Mechanism Version 3 (MCM v3) and has bee...

[1] We use a chemical transport model (GEOS-CHEM) to quantify the contribution of long-range transported pollution to the European ozone (O3) budget for the year 1997. The model reproduces the main features observed over Europe for O3, carbon monoxide and nitrogen dioxides, as well as two events of enhanced O3 of North American origin over the eastern North Atlantic and over Europe. North Ameri...

A large panel of German municipalities is employed in order to investigate the dynamic fiscal policy adjustment of local jurisdictions using a VEC model which explicitly takes account of the intertemporal budget constraint. The results confirm the central role of expenditure adjustment, nevertheless a substantial part of adjustment is due to changes in intergovernmental transfers, in particular...

We consider the optimal control problem of certain batch service queueing systems with compound Poisson arrivals and linear holding costs. The control problem involves the determination of the epochs at which the service is initiated as well as the sizes of the batches served. The service times are assumed to be independent and identically distributed, however, with a general distribution. A qu...

This paper derives a population sizing relationship for genetic programming (GP). Following the population-sizing derivation for genetic algorithms in Goldberg, Deb, and Clark (1992), it considers building block decision making as a key facet. The analysis yields a GP-unique relationship because it has to account for bloat and for the fact that GP solutions often use subsolutions multiple times...
