Frameworks for IT evaluation have been extensively discussed in the past. Until recently, research had concentrated on advancing classic approaches such as monetary cost/benefit considerations or strategic management matrices, but that constriction to known methods has considerably softened. More researchers now use economic models in IT evaluation. Their contributions open exciting new perspec...

It is rather difficult to forecast emerging technologies as there is no historical data available. In such cases, the use of bibliometrics and patent analysis have provided useful data. This paper presents the forecasts for three emerging technology areas by integrating the use of bibliometrics and patent analysis into well-known technology forecasting tools such as scenario planning, growth cu...

The purpose of the present paper is to build a system dynamics model for goal dynamics in organizations within a Dynamics Balanced Scorecard framework. In this paper it is proposed a model of goal dynamics in which Goal Setting and two other related Human Resources practices (Management by Objectives and Training) is viewed as a managerial tool able to enhance workers’ goal commitment, and ther...

Solid waste is one of the unavoidable products of every society that necessitates the establishment of municipal solid waste management system. Because of variability in quantity and composition of municipal solid wastes, several management scenarios are considered. Assessing the environmental impacts of the life cycle of these scenarios will have a significant role in reducing and resolving ur...

Surgical suits allocate a large amount of expenses to hospitals; on the other hand, they constitute a huge part of hospital revenues. Patient flow optimization in a surgical suite by omitting or reducing bottlenecks which cause loss of time is one of the key solutions in minimizing the patients’ length of stay[1] (LOS) in the system, lowering the expenses, increasing efficiency, and also enhanc...

Extreme torrent events in alpine regions have clearly shown a variety of process patterns involving morphological changes due to increased local erosion and deposition phenomena, and clogging of critical flow sections due to woody material accumulations. Simulation models and design procedures currently used in hazard and risk assessment are only partially able to explain these hydrological cau...

The purpose of the present work is to build a suitable system dynamics model for goal dynamics in organizations, as proposed by Barlas & Yasarcan (2008). The proposed model does not bear any ambition of being exhaustive: the main objective of this paper is to propose a model of goal dynamics in which Goal Setting, Management by Objectives and Training are viewed as human resource practices able...

facing the issues with structural complexity about which stakeholders have different views, has increasingly led to the use of soft systems methodology (ssm) in solving managerial problems. moreover, the flaws of this methodology in the stages of modeling and feasible, desirable changes, have provided the motivation for applying cognitive map (cm) and system dynamics in the ssm modeling. presen...

Congestion management in electricity markets is traditionally done using deterministic values of power system parameters considering a fixed network configuration. In this paper, a stochastic programming framework is proposed for congestion management considering the power system uncertainties. The uncertainty sources that are modeled in the proposed stochastic framework consist of contingencie...
