This paper presents a novel method for designing and sizing high-efficient hydrostatic transmissions (HTs) heavy duty propulsion applications such as agricultural construction machinery. The proposed consists in providing cost effective HT architectures that maximizes efficiency at the most frequent operating conditions of transmission, opposed to traditional design methods based on demanding r...

natural frequency is one of the parameters that represent useful information about the dynamic behavior of structures. controlling this parameter can decrease the probability of damage under dynamic loading. weight optimization on layout and sizing with frequency constraints is a well known problem because of its highly non-linear behavior. improved ray optimization (iro) algorithm is utilized ...

optimization models have been used to support decision making in production planning for a long time. however, several of those models are deterministic and do not address the variability that is present in some of the data. robust optimization is a methodology which can deal with the uncertainty or variability in optimization problems by computing a solution which is feasible for all possible ...

Shunt capacitors installation in distribution systems requires optimal placement and sizing. More harmonics are being injected into distribution systems. Adding shunt capacitors may lead to high distortion levels. The capacitor placement and sizing problem is a nonlinear integer optimization problem, with locations and ratings of shunt capacitors being discrete values. The goal is to minimize t...

This paper considers pricing and capacity sizing decisions, in a single-class Markovian model motivated by communication and information services. The service provider is assumed to operate a finite set of processing resources that can be shared among users; however, this shared mode of operation results in a service-rate degradation. Users, in turn, are sensitive to the delay implied by the po...

Pakistan is facing serious shortfall of electricity for few decades. Small hydropower projects can alleviate the worsening situation. The sizing of a low head hydropower plant plays a vital role in establishing the feasibility of the project. The plant needs to be optimized for energy produced, efficiencies of the plant components, number of units and its financial/economic parameters. This pap...
