Discrete multi-criteria decision problems with numerous Pareto-efficient solution candidates place a significant cognitive burden on the decision maker. An interactive, aspiration-based search process that iteratively progresses toward the most preferred solution can alleviate this task. In this paper, we study three ways of representing such problems in a DSS, and compare them in a laboratory ...

Coevolution can in principle provide progress for problems where no accurate evaluation function is available. An important open question however is how coevolution can be set up such that progress can be ensured. Previous work has provided progress guarantees either for limited cases or using strict acceptance conditions that can result in stalling. We present a monotonically improving archive...

background the efficiency of nasal surgeries can be determined by objective or subjective methods. we have assessed the effect of nasal obstruction after different nasal surgeries using acoustic rhinometry (ar) and nasal obstruction symptom evaluation (nose) scale. methods between may 2011 and may 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to otorhinol...

We present in this paper a general network DEA approach to deal with efficiency assessments in multi-stage processes. Our approach complies with the composition paradigm, where the efficiencies of the stages are estimated first and the overall efficiency of the system is obtained ex post. We use multi-objective programming as modeling framework. This provides us the means to assess unique and u...

Government budget balance forces the endogenous use of distortionary tax instruments when an exogenous reform is implemented. The aggregate efficiency of such reforms is based on comparisons of simple summary measures of the Marginal Cost of Funds of the various tariff or quota changes with the Marginal Cost of Funds of the alternative taxes, or of the Marginal Benefit of Government supplied go...

We study a T -period contracting problem where performance evaluations are subjective and private. We find that the principal should punish the agent if he performs poorly in the future even when the evaluations were good in the past, and, at the same time, the agent should be given opportunities to make up for poor performance in the past by performing better in the future. Thus, optimal incen...

one of the effective methods for improving the efficiency of an organization is benchmarking against successful organizations. not only benchmarking could be a technique for identifying problems but also it greatly helps managers in relations of the design of processes. among strategic and infrastructure industries in each country, the electricity industry is one of the most important and criti...
