estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. this study aimed to use the particle swarm optimization (pso) algorithm for automatic calibration of the hec-hms hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...
Abstract A prototype tool to assist architects during the early design stage of floor plans has been developed, consisting of an Evolutionary Program for the Space Allocation Problem (EPSAP), which generates sets of floor plan alternatives according to the architect's preferences; and a Floor Plan Performance Optimization Program (FPOP), which optimizes the selected solutions according to therm...
In this paper, we propose a method for supporting decision makers in the domain of supply chain management. Our objective is the global optimization instead of optimizing independent subsystems of the supply chain. The method architecture is based on combination of the simulation and optimization techniques which includes a multi-objectives optimization module and a simulation module. The optim...
in this paper, the application of neural networks for simulation and optimization of the cogeneration systems has been presented. cgam problem, a benchmark in cogeneration systems, is chosen as a casestudy. thermodynamic model includes precise modeling of the whole plant. for simulation of the steadysate behavior, the static neural network is applied. then using dynamic neural network, plant is...
An approach to the use of simulation and visualization of discrete event oriented simulation models for multi criteria scheduling optimization with genetic algorithms is described. A simulation model was used for fitness function computation of genetic algorithms’ results as well as for visual representation of process behavior of the chosen schedule after genetic algorithm optimization. In thi...
Experiment / simulation integrated shape optimization using variable fidelity Kriging model approach
This paper describes the application of Kriging metamodeling in multiple-objective simulation optimization. An Arenabased simulation model of an (s, S) inventory system is utilized to demonstrate the capabilities of Kriging metamodeling as a simulation tool. Response surface methodology and Kriging metamodeling are compared to determine the situations in which one approach might be preferred ov...
We study the maintenance task scheduling problem for an aircraft fleet in uncertain environment from viewpoint of robust optimization. Given a daily horizon, tasks delegated to shop should be scheduled such way that sufficient aircrafts are available on time meet demand planned missions. The either activities or unexpected repair jobs when major fault is detected during preor after-flight check...
The optimization of material flow systems requires a profound understanding the underlying processes. Business Process Model and Notation (BPMN) is an established way creating process model that allows interdisciplinary analysis optimization. Quantitative exploration using discrete-event simulation can help to enrich these insights. For reason, this paper introduces combined BPMN approach conne...
