In this paper, impacts of various uncertainties such as random outages of generating units and transmission lines, forecasting errors of load demand and wind power, in the presence of Demand response (DR) programs on power generation scheduling are studied. The problem is modelled in the form of a two-stage stochastic unit commitment (UC) which by solving it, the optimal solutions of UC as well...

This note estimates the long-run demand for skilled and unskilled labor using panel data for Colombian manufacturing plants. Unobserved heterogeneity and measurement error problems that commonly arise in microdata production estimates are examined. Output measurement errors cause OLS estimators to underestimate the output and wage response of employment demand. Time-difference estimators exagge...

Efficient hosting of applications in a globally distributed multi-tenant cloud computing platform requires policies to decide where to place application replicas and how to distribute client requests among these replicas in response to the dynamic demand. We present a unified method that computes both policies together based on a sequence of min-cost flow models. Further, since optimization pro...

Background Energy policies are promoting distributed energy resources such as energy efficiency, distributed generation (DG), energy storage devices, and renewable energy resources (RES), increasing the number of DG installations and especially variable output (only partly controllable) sources like wind power, solar, small hydro and combined heat and power. Intermittent generation like wind ca...

BACKGROUND AND OBJECTIVES: After having struck in a major natural disaster like an earthquake, different organizations run about to decrease losses. The lack of accurate demand information is a common problem that all emergency response organizations have to encounter such a crisis. Evaluation of the City disaster level is a mean to feed this informati...

extended abstract 1. introduction in arabic, words or letters that are considered to be jazm particles affecting a present tense are divided into two general categories: jazm particles affecting a single verb and those affecting two verbs. abbas hassan introduces particles such as iza, kayfa, lou, etc., which bear a conditional connotation, as a third factor for occurrence of jazm (al-nahv al-w...

The most convenient models of Solid Transportation (ST) problems have been justly considered a kind of uncertainty in their parameters such as fuzzy, grey, stochastic, etc. and usually, they suggest solving the main problems by solving some crisp equivalent model/models based on their proposed approach such as using ranking functions, embedding problems etc. Furthermore, there exist some shortc...

Immediately after a disruption, in order to minimize the negative impact inflicted on society, its imperative re-establish interdicted critical services enabled by infrastructure networks. In this paper, we study stochastic network recovery problem that tackles planning of restoration activities (considering limited resources) links so pre-disruption service flows can be re-established as quick...
