This paper considers the design and optimization of thermal systems on the basis of the mathematical and numerical modeling of the system. Many complexities are often encountered in practical thermal processes and systems, making the modeling challenging and involved. These include property variations, complicated regions, combined transport mechanisms, chemical reactions, and intricate boundar...

Dynamic optimization based on simulation is extremely time consuming. The quest for the optimal solution requires a vast number of iterations. Since the simulation is performed at each iteration step, the decrement of the simulation time becomes crucial. This paper presents the development of simulation models for dynamic optimization. The area of interest is paper and pulp industry. The keywor...

Abstract Public transport network design deals with finding efficient solution(s) from a set of alternatives that best satisfies the often-conflicting objectives stakeholders like passengers and operators. This work presents simulation-based optimization (SBO) model for designing public networks. The work’s novelty is in developing such fully accounts stochastic behavior commuters on transit ne...

Network simulator (ns-3) is a reputed simulation platform for performance evaluation of cellular networks. In this work, we explore the use ns-3 tracking successful handovers (HO) and handover failures consequent impact on 4G LTE network throughput with aim discovering new analytical relations about HOs methods to optimize resulting throughput. Decreased cell sizes in newer generation networks ...

simulation optimization is a scientific tool that is widely used to design and optimize comminution circuits in mineral processing plants. In this research, first of all, in order to  determine the suitable d80 for cicuit hydrocyclone underflow, the requiremed parameters of simulator (residence time distribution, breakage function, selection function and Plitt’s model calibration) were determin...

in this paper, we consider a stochastic time-cost tradeoff problem (tctp) in pert networks for project management, in which all activities are subjected to a linear cost function and assumed to be exponentially distributed. the aim of this problem is to maximize the project completion probability with a pre-known deadline to a predefined probability such that the required additional cost is min...
