in this paper power system model is represented in a new domain that relates to multi-resolution analysis (mra) space. by developing mathematical model of elements in this space using galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. the mathematical formulation and characteristics of new proposed space is expressed. als...

Modeling and simulation of processing plants are widely used in industry. Construction of a mathematical model for a plant is a time-consuming and error-prone task. In light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. Many software tools for modeling, simulation and optimization of proces...

This paper addresses a multi-objective mathematical model for the mixed-model two-sided assembly line balancing and worker assignment with different skills. In this problem, the operation time of each task is dependent on the skill of the worker. The following objective functions are considered in the mathematical model: (1) minimizing the number of mated-stations (2), minimizing the number of ...

Production leveling (heijunka) is one of the lean tool that is used to stabilize a manufacturing system (reduce the bullwhip effect). Production leveling is a kind of cyclic scheduling that creates production regularity and coordination simplicity. This article describes simulation modeling and multivariate analysis of an assembly production line in a microelectronics factory. The assembly line...

Optimization of Supply Chains: A Continuous Approach Ciro D’Apice, Simone Göttlich, Michael Herty, and Benedetto Piccoli This book offers a state-of-the-art introduction to the mathematical theory of supply chain networks, focusing on those described by partial differential equations. The authors discuss modeling of complex supply networks as well as their mathematical theory; explore modeling,...

Many real life problems contain imprecise variables, constraints and objectives. Fuzzy set theory gives an opportunity to handle imprecise terms in such situations. Two-sided assembly line balancing (2sALB) problem which is a generalization of the well known simple assembly line balancing problem can also be modeled more realistically by employing fuzzy approaches. Such an approach is presented...

In this paper, we propose a hierarchical optimization technique of the PCB assembly line including multi-head non-identical surface mounting machines. The optimization problem related to the PCB assembly line is generally divided into three sub-problems: a line balancing problem, a reel assignment problem and a pick-and-place sequencing problem. Since each problem is known to be combinatorial a...

With the rapid development of the industry sector, the assembly line has also experienced development, whose rationality determines the production efficiency of industrial production. In this paper, in order to address the balancing issue of assembly lines for industrial production, a combinatorial optimization method is proposed for the optimization and implementation of the assembly line base...

This study presents a new method [In–Out Combined Dynamic Weighted Round-Robin (CDWRR)] for balancing network loads in multiple link environments that provide both input and output interfaces. The purpose of this research is to balance loads for reducing Internet traffic jams. Using the novel line detection prediction approach, the main benefit of the presented algorithm is that it does not nee...
