In this paper, a general elastoplastic-damage constitutive model considering the effect of strain rate has been developed. The derivation of this model has been cast into the irreversible thermodynamics with internal variables within the fundamentals of Continuum Damage Mechanics (CDM). The rate effect has been involved as an additional term into the plastic yield surface (dynamic plastic yield...

Setting up and using realistic wide area testbeds for developing and testing large-scaled distributed applications and communication mechanisms may be very expensive. Therefore, designers use simulative technologies to obtain elastic and reproducible frameworks where those experiments may be safely carried out in local lab-based environments. Conventional simulators are based on the idea that t...

As the number of available models as well as their complexity grows, model reuse becomes increasingly interesting. However, building new models based on reusing existing ones poses several challenges, and among others, checking validity of the newly built model and the model reuse is of paramount importance. The modeling process is typically accompanied by executing simulation experiments, e.g....

Uncertainty in production prediction has been subject to numerous investigations. Geological and reservoir engineering data comprise a huge number of data entries to the simulation models. Thus, uncertainty of these data can largely affect the reliability of the simulation model. Due to these reasons, it is worthy to present the desired quantity with a probability distribution instead of a sing...

asimulation-optimization approach is proposed for replenishment planning andshelf space allocation. the customers’ demand is divided into fixed andvariable demand. each customer follows a given path while shopping in thestore. by dividing the store space into several zones and calculating therelated substantial and random utilities, an analytical equation is proposedfor the probability of zone ...

in this paper, the pricing of a european call option on the underlying asset is performed by using a monte carlo method, one of the powerful simulation methods, where the price development of the asset is simulated and value of the claim is computed in terms of an expected value. the proposed approach, applied in monte carlo simulation, is based on the black-scholes equation which generally def...

A switched-capacitor-based battery equalizer using level-shift circuits is proposed in this paper. In conventional equalizers using diode switches, the threshold voltage of diode switches causes a decrease in power efficiency. Unlike conventional equalizers, the proposed equalizer alleviates the threshold-voltage-drop of switches by using level-shift circuits. Therefore, the proposed equalizer ...

We present the basic concepts of experimental design, the types of goals it can address, and why it is such an important and useful tool for simulation. A well-designed experiment allows the analyst to examine many more factors than would otherwise be possible, while providing insights that could not be gleaned from trial-and-error approaches or by sampling factors one at a time. We focus on ex...
