T his study investigates the factors affecting the demand for new residential buildings in urban areas of Iran during 1976-2010. The demand function for new residential buildings in urban areas was estimated and then the existence of a long-run relationship among variables of this function was studied using the Bounds testing of the Autoregressive Distributed Lag Co-integration procedure. The t...

Dynamic resource management has become an active area of research in the Cloud Computing paradigm. Cost of resources varies significantly depending on configuration for using them. Hence efficient management of resources is of prime interest to both Cloud Providers and Cloud Users. In this work we suggest a probabilistic resource provisioning approach that can be exploited as the input of a dyn...

OBJECTIVE To characterize the impact of widespread inventory management policies on stock-outs of essential drugs in Zambia's health clinics and develop related recommendations. METHODS Daily clinic storeroom stock levels of artemether-lumefantrine (AL) products in 2009-2010 were captured in 145 facilities through photography and manual transcription of paper forms, then used to determine his...

In a manufacturing system with flexible capacity, inventory management can be coupled with capacity management in order to handle fluctuations in demand more effectively. A typical example is the effective use of temporary workforce. In this paper, we discuss an integrated model for inventory and flexible capacity management under nonstationary stochastic demand with the possibility of positive...

In this paper, based on error correction model by using panel data, an empirical analysis of demand for international reserves for 16 Islamic countries is investigated. Besides addressing conventional issues, the model explicitly incorporates the impact of expected export revenues and the impact of the exchange rate system on reserve demand. The results reveal that, short run money market diseq...

Future multiservice networks will be extremely large and complex. In this environment, Active Services will be needed to enable the rapid service evolution demanded by users. Active services also enable service management to be delegated to network users as a large set of independent small-scale management systems, thus minimising management costs. However, novel management solutions will be re...

gasoline is the most important energy product in the passenger transportation sector in iran. gasoline demand survey has a high priority in iran because of its ever-increasing consumption. the most important challenges for this purpose are uncertainties resulting from structural failure of economy, changing of policies and lack of accurate data. this research aims to specify the variables expla...

This paper presents the architecture, the policy schema, and the policy specifications necessary to accomplish effective management of the Application Level Active Networking (ALAN) environment. Using ALAN, developers can engineer applications through the network by utilising platforms (active servers) on which 3 party software (proxylets) can be dynamically loaded and run. Redirection of packe...

Activity-based models appeared as an answer to the limitations of the traditional trip-based and tour-based four-stage models. The fundamental assumption of activity-based models is that travel demand is originated from people performing their daily activities. This is why they include a consistent representation of time, of the persons and households, time-dependent routing, and microsimulatio...

The Korean government announced new policies to regulate mortgage lending that aim to decrease both the loan-to-value ratio and the debt-to-income ratio, in 2008. These policies were implemented on the expectation that they will control housing demand and stabilize house prices, focusing only on the current market status. However, it is difficult to analyze the effectiveness of these kinds of p...
