The use of computer modeling is fast increasing in almost everyscientific, engineering and business arena. This dissertationinvestigates some challenging issues in design, modeling andanalysis of computer experiments, which will consist of four majorparts. In the first part, a new approach is...

The growth of international markets as well as business partnerships between U.S. and Asian-based firms has lead to an increased interest in an economically viable business jet capable of supersonic cruise and trans-Pacific range with one stop over (or non-stop trans-Atlantic range) 1 . Such an...

Increased rate of use of fossil fuels have greatly polluted the earth through harmful by-products. Biodiesel is an attractive substitute to fossil fuel in compression ignition engine applications. In this research work, vegetable oil namely Arachis Hypogaea Oil (AHO) is used along with ethanol...

In this work, the catalytic upgrading of a bio-oil model compound via esterification with ethanol was studied using 12-tungstosilicic acid as the catalyst. The response surface method was used to investigate and optimize the process variables, which include the ethanol to acid molar ratio,...

Purpose – The purpose of this paper is to introduce a method of the bottleneck detection for Emergency Department (ED) improvement using benchmarking and design of experiments (DOE) in simulation model. Design/methodology/approach – Four procedures of treatments are used to represent ED...

Purpose – The purpose of this paper is to provide a case study on endorsing process improvement in maritime operations by implementing design of experiments on Lean Six Sigma performance responses. It is demonstrated how process efficiency and environmental muda may be dealt with...

Response surface methodology (RSM) is used for optimality analysis of the cost coefficients in mixed integer linear programming. This optimality analysis goes beyond traditional sensitivity and parametric analysis in allowing investigation of the optimal objective function value response over...

The evaluation of training programmes is discussed: objectives must be defined and a proper experimental design must be used. The article describes a field study in “Self‐esteem Training” which was also used to examine the application of the Solomon four group design. It was shown that...

Advancing technology applied to engineering production processes can result in improved output quality. However, customer requirements for improved product quality are progressing at a comparable or faster rate, which can result in increased rework and scrap levels when operating at the limits...

The goal of factor screening is to find the really important inputs (factors) among the many inputs that may be changed in a realistic simulation experiment. A specific method is sequential bifurcation (SB), which is a sequential method that changes groups of inputs simultaneously. SB is most...
