This paper introduces an approach to cope with the representational inappropriateness of traditional flat file format for data sets from databases, specifically in database clustering. After analyzing the problems of the traditional flat file format to represent related information, a better representation scheme called extended data set that allows attributes of an object to have multi-values ...

Many choices consumers face are over outcomes that consist of multiple attributes. For instance, when deciding to purchase a particular product consumers must account for both its price and its brand. Although these choices are quite common, we know relatively little about how changes in consumer attention to specific attributes impacts decisions. We propose a new computational model, the multi...

Parallel coordinates is one of the most popular and widely used visualization techniques for large, high dimensional data. Often, data attributes are visualized on individual axes with polylines joining them. However, some data attributes are more naturally represented with a spherical coordinate system. We present a novel coupling of parallel coordinates with spherical coordinates, enabling th...

In this paper non-classical logical techniques are introduced to formalize the analysis of multiinterpretable observation information, in particular in approximate classification processes where information on attributes of an object is to be inferred on the basis of observable properties of the object. One frequently occurring reason for imperfect classification is when the available observati...

Six Sigma is a strategy for achieving process improvement and operational excellence within an organization. Decisions on critical parameter selection in analysis phase are always very crucial; it plays a primary role in successful execution of Six Sigma project and for productivity improvement in manufacturing environment and involves the imprecise, vague and uncertain information. Using a cas...

In order to produce and develop a s oftware system, it is necessary to have a method of choosing a s uitable software architecture which satisfies the required quality attributes and maintains a trade-off between sometimes conflicting ones. Each software architecture includes a set of design decisions for each of which there are various alternatives, satisfying the quality attributes differentl...

in this paper we propose a relatively new semi-analytical technique to approximate the solution ofnonlinear multi-order fractional differential equations (fdes). we present some results concerning to the uniqueness of solution of nonlinear multi-order fdes and discuss the existence of solution for nonlinear multi-order fdes in reproducing kernel hilbert space (rkhs). we further give an error an...

data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) with multiple inputs and outputs. the traditional dea treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. this carries the notion of missing some intermediate measures in the process of changing the inputs to...

results the total art score was equal to 30.07 ± 12.43. data analysis from art illustrated that 74.6% of 240 cases were in high and 13.8% were in medium level of risk. art-electre results revealed that grading and pars naghsh halls were in the best and decoration hall was in the worst ergonomic conditions and should be placed in the top priority of action level. background in this paper, the er...

strategic environmental assessment can be viewed as a process to integrate the concept ofsustainable development into planning. in this context, sea can be regarded as a method that regulates theplanning process to a state of sustainable development. however, to reach that goal it is necessary to achieve full integration of planning and the sea process.therefore this paper considers the integra...
