Simulation optimization: a comprehensive review on theory and applications: 1. Introduction With the continuing developments in computer technology, simulation is receiving increasing attention as a decision-making tool. Most real-world systems are so complex that computing values of performance measures and finding optimal decision variables analytically is very hard and sometimes impossible. Therefore, computer simulation is frequently used in...; Tags: algorithm, computer, conference, derivative, Engineering, G., gradient, IEEE, M., manufacturing, Nelson, optimization, performance, technique, theory, Wiley, Winter; Research articles 2004-11-01

Weather Fundamentals: Weather FundamentalsTHE EARTH'S ATMOSPHERECompositionAir is a mixture of several gases. When completely dry, it is about 78% nitrogen and 21% oxygen. The remaining 1% is other gases such as argon, carbon dioxide, neon, helium, and others. However, in nature, air is never completely dry. It always contains some water vapor...; Tags: Air Force, gradient, latitude, Manufacturing, Mercury, radiation, vapor; Research articles 2004-01-01
construction of Aberdeenshire's first turnpike roads, The: Construction of the first turnpike road in the shire county of Aberdeen in the north-east of Scotland commenced in 1796.1 This was more than 130 years after the establishment of the first turnpike trust in England and over forty-five years after the first turnpike gate in Scotland had been erected...; Tags: Aberdeen Group Inc., Agriculture, construction, drain, gradient, North, roadway, Scotland, specification; Research articles 2003-09-01
Thermal gradient coating resists heat checking in pins. (Surface Engineering).: A coating deposited via the large area filtered arc deposition LAFAD process, which provides better thermal fatigue resistance to heat checking in core pins for die casting, has reportedly been developed by UES, Dayton, Ohio, in collaboration with the Ohio State University, Columbus.

New approach to evaluating groundwater flow provides insight at landfill. (Casebook).(Brief Article)(Statistical Data Included): The non-aqueous phase liquids NAPL plume at the 15-acre Hyde Park landfill site, Niagara County, N.Y., changed configuration significantly during 19 years of remedial action. Continual transformation made it difficult to attain local inward hydraulic gradients and prevent further contaminant migration. Bedrock below the site consists...; Tags: gradient, monitoring, U.S. Environmental Protection Agency; Research articles 2001-11-01

Optimization of discrete event systems via simultaneous perturbation stochastic approximation: 1. IntroductionWe consider the problem of optimizing a stochastic discrete event system under the overriding assumption that the system cannot be adequately modeled using analytical means, e.g., optimizing the operations of a complex manufacturing system. For such systems, simulation is often used to estimate performance. Under suitable conditions, the resulting...; Tags: algorithm, Alpha, Delta, Engineering, gradient, IEEE, M., network, Omega, optimization, performance, technique, Winter; Research articles 1997-03-01
