The number of trips by private cars has significantlyincreased in recent decades in many cities. At the sametime, parking capacities have not kept up with thisincrease in urban travel demand. Parking facilitiesmanagement has significant influence on the ...

One of the most important issue in transportation systemanalysis deals with modeling of the effects of AdvancedTraffic Information Systems (ATIS) on users' route choicebehaviour and how incorporate such effects in trafficassignment models. To face this ...

This study is an investigation into the applicability ofprospect theory in the context of morning commutes. Weextend the analysis adopted in our previous study toaccount for both observed and unobserved heterogeneityacross commuters. Two decision frames ...

The authors are in the process of developing a finiteelement-based time-domain system identificationalgorithm which will identify structural parameters atthe local element level without using input excitationinformation and with limited output ...

Complicated structural systems are routinelyanalyzed using the finite element algorithm. In this waynonlinearities due to geometry and materialcharacteristics, boundary or support, and connectionconditions can be easily incorporated in the ...

In this paper a fuzzy method for determining appropriatestructural design is presented. Non-stochastic uncertaintyis quantified using fuzzy values and fuzzy random variables.Fuzzy structural parameters are processed on the basis of agenerally applicable ...

The main objective of this study is to address the riskanalysis of the water ingress to underground concretestructures. The reliability level of the safety measuresaccounted for in the design process, to ensure optimalwater resistance and durability of ...

Fuzzy-as has been emphasized by Zadeh-is ahuman interface, a link between human judgement andmachine information processing. It represents anapproach for experimentation with the sensitivity ofhuman classification, i.e. the notion of adding ...

We start by determining fuzzy numbers \overline \lambda (\overline \mu) for the arrival(service) rate for a fuzzy queuing system. These fuzzynumbers are then used to compute the fuzzy steady stateprobabilities which in turn are employed to calculate ...

A novel concept of probabilistic fuzzy system (PFS) hasbeen first proposed and a general framework for itsrepresentation has been developed here. Unlike the wellestablished concept of fuzzy probability, which incorporatesfuzziness in probabilities, PFS ...

The fuzzy sets adopted for the development of fuzzysignal controllers, and their respective membershipfunctions, are recognised as important aspects related tocontroller operations. However, the impact of theirdefinitions on traffic signal performance ...

Efficient and successful use of Genetic Algorithms(GAs) requires careful selection of several parametervalues. One such critical parameter is the processingtime (or, number of generations) that is sufficient toensure suitable convergence. To-date there ...

The impact of weaving vehicles on the capacity offreeway segments is uncertain due to the complexity inoperation. The Highway Capacity Manual 2000provides values for capacity on various weavingsegments (Exhibit 24-8) based on sets of conditions(...

This paper aims at showing that Artificial NeuralNetworks (ANN) can be an effective tool for traveldemand analysis. Exiting literature show that ANN's canoutperform commonly adopted models, derived fromrandom utility theory, but they are based on ...

This paper presents a reliability analysis of a precisiondrilling process used in the manufacturing of aircraftstructural components. After a brief introduction to theprecision drilling manufacturing process, a reliabilityanalysis is executed through ...

This paper discusses methods for solvingsteady state process optimization problems underparametric uncertainty.The problem is formulated asa two-stage optimization problem (TSOP) which isinherently multiextremal and nondifferentiable.Anindirect approach ...

Text categorization is the classification to assign a textdocument to an appropriate category in a predefined setof categories. This paper focuses on the special case whencategories are organized in hierarchy. We presents a newapproach on this recently ...

In this paper, we make an improvement onMcCahon and Lee's algorithm for two-machineflow shop problem with uncertain processingtime represented with fuzzy number. Especially,the scheme used in McCahon and Lee'salgorithm for ranking fuzzy processing times ...

For many important applications, it would beparticularly valuable if large numbers of relatively simple(i.e. unintelligent) agents could be induced to collaboratein the performance of tasks in environments in which ahigh degree of uncertainty is the ...

This paper applies simulation-basedoptimization to the problem of vessel trafficmanagement in a high vessel density environment.Specifically, a Monte Carlo simulation has beendeveloped that models a relatively small craftoperating in a high vessel ...

We propose a self-organizing neural structure with dynamicand spatial changing weights for forming a featurespace representation of concepts. An essential core of thisself-organization is an appropriate combination of an unsupervisedlearning with ...

The exchange of information between two agents overthe Semantic Web requires a means of translatingbetween the "vocabularies" of the agents. Muchresearch has focused on the use of ontologies forspecifying an agent's knowledge and for ...

The computational neural-network structures described inthe literature are often based on the concept of linear neuralunits (LNUs). The biological neuron is a complex computingelement, which performs more computations than just linearsummation. The ...

The paradigm commonly used to analyze discrete choicebehavior, especially within a transportation system, isbased on the assumption of a perfectly rational decision-maker,whose perceived utility is modeled taking intoaccount several sources of ...
