In the old days, the price for IT services was formed in a pretty standardized way. Network services had an explicit usage price per Kbit/ sec. The range of provided IT services have been growing very fast and have reached new dimensions of complexity. From infrastructure pricing to web-enabled application availability and performance nowadays the old rules for defining service pricing is not a...

Cost-effectiveness analyses (CEAs) of behavioral interventions typically use physical outcome criteria. However, any progress in cognitive antecedents of behavior change may be seen as a beneficial outcome of an intervention. The aim of this study is to explore the feasibility and validity of incorporating cognitive parameters of behavior change in CEAs. The CEA from a randomized controlled tri...

Pierre Schaus, Pascal Van Hentenryck, Alessandro Zanarini Dynadec, Brown University {pschaus,pvh,alessandro.zanarini}@dynadec.com Abstract. The Soft Global Cardinality Constraint (softggc) relaxes the Global Cardinality Constraint (gcc) by introducing a violation variable representing unmet requirements on the number of value occurrences. A first domain consistent filtering algorithm was introd...

Cost estimation generally involves predicting labor, material, utilities or other costs over time given a small subset of factual data on “cost drivers.” Statistical models, usually of the regression form, have assisted with this projection. Artificial neural networks are non-parametric statistical estimators, and thus have potential for use in cost estimation modeling. This research examined t...

Long lasting systems like airplanes have a cost structure where the maintenance costs are larger than the purchasing costs. Besides, the growing amount of electronics leads to a much higher sensitivity with respects of failures in the electronic system. Testing is required, both for preventive maintenance as well as repair. Previously we have looked at the impact of test and design for testabil...

This study has designing the model that uses case-based reasoning (CBR) in order to use materials model and cost mode in management application. It intends to improve system effect through expression the method for case, the method for retrieving materials model and cost model, the method for materials model, and cost modeling procedure through case-based reasoning then it ultimately aims at im...

according to the importance of customer in competitive environment, especially in banking industry, regarding that the cost of catching (attracting) new customers is several times higher than the cost of keep customer loyal to organization, cause that examining ways of becoming loyal customer to product (goods/ services) has high preference in market research. this research, shows that we can c...

uncertainty plays a major role in any project evaluation and management process. one of the trickiest parts of any production project work is its cost and time forecasting. since in the initial phases of production projects uncertainty is at its highest level, a reliable method of project scheduling and cash flow generation is vital to help the managers reach successful implementation of the pr...
