Abstract Simulation–optimization approaches are useful methods for the assessment of water resource engineering plans and finding best management policy at watershed scale. In this study, to find optimum operation a reservoir with purpose satisfying demands while meeting quantity quality criteria, generic river basin simulation model (MODSIM) is coupled particle swarm optimization (PSO) algorit...

In this research, a stochastic simulation based design tool that facilitates design in a dynamic environment is developed. The simulation includes a full dynamic model of an Autonomous Underwater Vehicle (AUV) that was developed to evaluate the effectiveness of such a craft given a set of physical attributes. These attributes include but are not limited to: speed, mass, moments of inertia, cont...

The question we consider in this paper is: “When may a combination of (fine-grain) executionbe contracted into an abstract (atomic) action execution”? Our answer is basically: “When noobserver can see the difference.” This is worked out in detail by defining a notion of so-calledcoupled splitting/contracting simulation between systems which differ in the atomicity of theirac...

The bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. Then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. Furthermore, simulation and optimization based on this reactor model are carried out. The results of sim...

Based on MATLAB/SimEvents simulation platform and genetic algorithm, the simulation and optimization of energy consumption in hybrid flow shop is studied. Considering workshop layout and workpiece path, machining process simulation in hybrid flow shop is realized. With the processing time, processing power and stand-by power introduced into simulation model, the energy consumption simulation in...

Microstrip antenna is gathering a lot of interest in communication systems. Genetic algorithm is a popular optimization technique and has been introduced for design optimization of proximity coupled antenna. Patch length, patch width are taken as optimization parameters. Return loss and radiation pattern for the optimized antenna are verified using IE3D software. Accuracy of the results encoura...

ion in this study area. Different groundwater extraction scenarios were generated using Latin hypercube sampling. The salinity concentrations resulting from each of these pumping patterns are simulated using FEMWATER. The simulated salinity level and the corresponding pumping rates form the input-output pattern. Altogether 230 extraction patterns are used in this study. Different realizations o...

Finite element (FE) modeling and multibody dynamics have traditionally been applied separately to the domains of tissue mechanics and musculoskeletal movements, respectively. Simultaneous simulation of both domains is needed when interactions between tissue and movement are of interest, but this has remained largely impractical due to the high computational cost. Here we present a method for th...

Well placement optimization is a very challenging problem due to the large number of decision variables involved and the nonlinearity of the reservoir response as well as of the well placement constraints. Over the years, a lot of research has been done on this problem, most of which using optimization routines coupled to reservoir simulation models. Despite all this research, there is still a ...
