This paper investigates three disparate design cases where the newly developed s-Pareto frontier based concept selection paradigm is used to compare competing design concepts under a multiobjective optimization framework. The new paradigm, which was recently introduced by the authors, is based on the principle of Pareto optimality – a principle that defines an important class of optimal solutio...

When analyzing the productivity of rms one may want to compare how the rms transform a set of inputs x typically labor energy or capital into an output y typically a quantity of goods produced The economic e ciency of a rm is then de ned in terms of its ability of operating close to or on the production frontier which is the boundary of the production set The frontier function gives the maximal...

Among all aspects of IT Portfolio Management (ITPM), we find the key concept of efficient frontier to be the most applicable illustration for managing IT resources as multiple heterogeneous IT portfolios. To better assist decision-makers (e.g., senior executives) in selecting the most qualified IT portfolio choice, we propose a new IT Portfolio Efficient Frontier model that incorporates decisio...

SWAMY leaves of X appear consecutively at either the left or the right end of the frontier, with at least one nonpertinent leaf appearing at Absrruct--In this paper, we first point out that the planarization althe other end of the frontier. gorithm due to Ozawa and Takabashi [4] does not in...

A stochastic cost equation was estimated for US dairy farms using national data from the production year 2000 to determine how farmers might reduce their cost of production. Cost of producing a unit of milk was estimated into separate frontier (efficient) and inefficiency components, with both components estimated as a function of management and causation variables. Variables were entered as im...

There arises situations where an autonomous robot needs to navigate to a target location and no information is available about the terrain. Frontier based navigation is one of the most efficient methods of exploration and navigation for such situations. In a frontier based strategy, the robot navigates to the target location by detecting intermediate frontier regions, which are points lying on ...

In a questionnaire study the effects of discourse structural information on resolving inter-sentential anaphora were investigated. The Right Frontier Constraint, first proposed by Polanyi (1988), states that potential antecedents of an anaphor that are placed at the right frontier of a discourse unit can be accessed more easily than antecedents that are placed somewhere else. Participants (N=36...

Data envelopment analysis (DEA) is one of the vastly available literature on efficiency analysis. In general, decision making units (DMUs) can be measured from two perspectives, optimistic and pessimistic. Two different perspectives lead to conflicting biased scale measurements. To deal with problem, in this paper, we introduce a double frontier approach integrate both pessimistic efficiencies'...

Tree pattern matching (tpm) algorithms play an important role in practical applications such as compilers and XML document validation. Many tpm algorithms based on tree automata have appeared in the literature. For reasons of efficiency, these automata are preferably deterministic. Deterministic root-to-frontier tree automata (drftas) are less powerful than nondeterministic ones, and no root-to...
