This survey considers the optimization of simulated systems. The simulation may be either deterministic or random. The survey reflects the author’s extensive experience with simulationoptimization through Kriging (or Gaussian process) metamodels using a frequentist (non-Bayesian) approach. The analysis of Kriging metamodels may use bootstrapping. The survey discusses both parametric bootstrappi...

Lean production refers to approaches initially developed by Toyota that focuses on the elimination of waste in all forms. Lean has been extremely successful in large high volume manufacturers. However, many small to medium size low volume manufacturers have not fully embraced the potential benefits of a lean production system. This paper focuses on the implementation of lean in a small manufact...

the basic type of assembly line balancing (alb) problem is the allocation of work elements to a set of production work stations considering cycle time, precedence constraints, and assembly diagram to achieve predefined performance criteria such as line efficiency and smoothness index. in this paper, a mixed integer programming model for solving multiple product alb problems with processing time...

We present a new mathematical model for the assembly line balancing problem with the objective of maximizing the line comfort to operators. Besides minimizing discrepancies between the ergonomic risks of workstations, balancing is subject to temporal and spatial conditions for the workstations. To evaluate the performance of the proposed model, we compare it with other mathematical model whose ...

The paper presents the results of simulation modeling functional capabilities pulse converters alternating voltage with free circulation energy two types: inverter type intermediate link pulsating and matrix discharge reactive load into network. With help a software package OrCAD, main modes operation these are investigated: lowering increasing output relative to input. each mode presented in f...

consideration of the current-voltage (i-v) characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (mppt). having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. in this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathema...

This paper discusses modeling and parameter estimation of PMSM. The design of a control system for a high performance drive requires a mathematical model of the motor. This is usually derived from physical principles, then the parameters of the motor are determined through off-line testing or estimated on-line from input/output operating records data. The dynamics of synchronous motor can be de...

the aim of this paper is to minimize output phase noise for the pure signal synthesis in the frequency synthesizers. for this purpose, first, an exact mathematical model of phase locked loop (pll) based frequency synthesizer is described and analyzed. then, an exact closed-form formula in terms of synthesizer bandwidth and total output phase noise is extracted. based on this formula, the phase ...
