with the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

We consider interruptible electricity contracts issued by a distributor of electricity, that allow for interruptions to electric service in exchange for either an overall reduction in the price of electricity delivered, or for financial compensation at the time of interruption. We provide an equilibrium model to determine electricity prices, based on stochastic models of supply and demand. In t...

This paper presents a stochastic optimization model and efficient decomposition algorithm for multi-site capacity planning under the uncertainty of the TFT-LCD industry. The objective of the stochastic capacity planning is to determine a robust capacity allocation and expansion policy hedged against demand uncertainties because the demand forecasts faced by TFT-LCD manufacturers are usually ina...

The inventory control of the products which have intermittent demand is essential for many organizations since these items have a low lead time demand but a high price. Since the intermittent demand pattern is irregular, the estimation of the lead time demand is challenging. A modified Markov chain model (MMCM) has been proposed for modeling and estimating intermittent demand data, motivated by...

Imbalances in supply and demand often cause the price for the same good to vary across geographic locations. Economic theory suggests that if the price differential is greater than the cost of transporting the good between locations, then buyers will shift demand from high-price locations to lowprice locations, while sellers will shift supply from low-price locations to high-price locations. Th...

In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...
