The purpose of this paper is to examine whether shocks the consumption petroleum products in Jordan have permanent or temporary effects. This has been accomplished by applying Lee and Strazicich (2003) test unit root with structural breaks investigate stationarity properties related time series over period 1961 2019. Empirical findings lend evidence that a process, implying impact, does not tur...

Management of today’s systems is becoming increasingly complex due to the heterogeneous nature of the infrastructure under which they operate and what the users of these systems expect. Our interest is in the development of mechanisms for automating the management of such systems to enable efficient operation of systems and the utilization of services. Central to autonomic management is the nee...

this study is focused on developing an integrated optimization-simulation based genetic algorithm model (iosga) to develop the operational policies for a multi-purpose reservoir system. the objective function of the optimization model is considered to be a linear function of reliability (rel), resiliency (res), and vulnerability (vul) of the river-reservoir system. genetic algorithm (ga) is emp...

In capacitated production systems at high utilization there exists a nonlinear relationship between the orders which are in process and the output. This nonlinear relationship can be described by nonlinear Clearing Functions. We show how a Clearing function will be estimated and integrate it into a model of order releases planning. We compare our model with two inventory management policies und...

this paper examines the application of a gis based planning support system, what if? tm, to evaluate alternative growth policies for sustainable urban growth in a rapidly growing city of iran. the paper describes the study area, dorood city, and the what if? model. it then explains the procedures that were used to obtain the required data and to run the model to dorood city. the paper concludes...

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 ...

This paper discusses the need and scope for an active fiscal stabilization policy. It is argued that the effectiveness of fiscal policy as a short run stabilizer does not depend on the long run multipliers of (balanced budget) fiscal policies. To the extent that activity can be affected by aggregate demand in the short run, there is a case for a fiscal stabilization policy in terms of temporary...
