Who's my Neighbour? European Political Economy Review No. 7 (2007), p. 24-37
No full textThis paper will propose a reconsideration of the term “neighbour” in the conviction that this operation is of fundamental importance in order to solve any eventual misunderstanding on its meaning and to define what the nature of a relationship of neighbourhood may imply. In particular, it will look into the literature to show that this term, far from being uncontested, fundamentally implies an “othering” practice which transcends the Christian teaching to “love one’s neighbour as oneself”. Then, it will underline that this word may have different connotations in partner countries which may go beyond a neutral indication of geographical proximity and which may not correspond to the meaning consolidated in the anglo-saxon tradition which basically refers to a neighbour as to a “fellow”. Finally, the paper will underline that the same fundamental ambiguity which marks the term here considered lies at the very core of the ENP. As a matter of fact, this policy shows persisting uncertainties on how to substantiate the relationship with neighbouring countries, whether in terms of fellowship and integration or in terms of an “other than me” who still represents a security threat
Who`s My Neighbour?
No full textThe EU is approaching bordering countries offering them Òneighbourhood relationsÓ, but it fails short of taking into consideration how this concept may be perceived by its partners. This paper will propose a reconsideration of the term ÒneighbourÓ in the conviction that this operation is of fundamental importance in order to solve any eventual misunderstanding on its meaning and to define, in the context of the ENP, what the nature of a relationship of neighbourhood may imply. In particular, it will look at the literature to show that this term, far from being uncontested, fundamentally implies an ÒotheringÓ practice which transcends the Christian teaching to Òlove oneÕs neighbour as oneselfÓ. Then, it will underline that this word may have different connotations in partner countries which may go beyond a neutral indication of geographical proximity and which may not correspond to the meaning consolidated in the Anglo Saxon tradition which basically refers to a neighbour as to a ÒfellowÓ. Finally, the paper will underline that the same fundamental ambiguity which marks the term here considered lies at the very core of the ENP. As a matter of fact, this policy shows persisting uncertainties on how to substantiate the relationship with neighbouring countries, whether in terms of fellowship and integration or in terms of an Òother than meÓ who still represents a security threat.Neighbourhood, ENP, integration-security dilemma
Uncertainty Management in Simulation-Optimization of Complex Systems : Algorithms and Applications
No full textConnections Among Optimization Models with Uncertainties, ABC and RBV
No full textOptimization models (in particular, with uncertainties) and Activity Based Costing (ABC) and Resource Based View (RBV) of the firm theory are usually separated in theory and applications. We analyze the connections among them, with a focus on stochastic programming, showing how they can all be used as decision support instruments for strategic planning problems, especially concerning resources and services (or products). Such connections produce a multiplicative positive effect as we can use the potential of mathematical modeling with data from the ABC system and a taxonomy of resources from the RBV: the latter can also help us for the interpretation of results after applying stochastic (or mathematical) models and solution methods
Uncertainty Management in Simulation-Optimization of Complex Systems : Algorithms and Applications
No full textMetamodel-based robust simulation-optimization:An overview
No full textOptimization of simulated systems is the goal of many methods, but most methods assume known environments. We, however, develop a "robust" methodology that accounts for uncertain environments. Our methodology uses Taguchi's view of the uncertain world but replaces his statistical techniques by design and analysis of simulation experiments based on Kriging (Gaussian process model); moreover, we use bootstrapping to quantify the variability in the estimated Kriging metamodels. In addition, we combine Kriging with nonlinear programming, and we estimate the Pareto frontier. We illustrate the resulting methodology through economic order quantity (EOQ) inventory models. Our results suggest that robust optimization requires order quantities that differ from the classic EOQ. We also compare our results with results we previously obtained using response surface methodology instead of Kriging
Simulation-optimization under uncertainty through metamodeling and bootstrapping
No full textMost methods in simulation-optimization assume known environments, whereas this research accounts for uncertain environments combining Taguchi's world view with either regression or Kriging (Gaussian Process) metamodels (response surfaces). These metamodels are combined with Non-Linear Mathematical Programming (NLMP) to find a robust optimal solution. Varying the constraint values in the NLMP model gives an estimated Pareto frontier. To account for the variability of the estimated Pareto frontier, this research uses bootstrapping which gives confidence regions for the robust optimal solution. This methodology is illustrated through the Economic Order Quantity (EOQ) inventory-management model, accounting for the uncertainties in the demand rate and the cost coefficients
