Nonparametric Empirical Bayes for the Dirichlet Process Mixture Model

The Dirichlet process prior allows flexible nonparametric mixture modeling. The number of mixture components is not specified in advance and can grow as new data come in. However, the behavior of the model is sensitive to the choice of the parameters, including an infinite-dimensional distributional parameter G0. Most previous applications...

A Formulation and Solution Algorithm for Fuzzy Dynamic Traffic Assignment Model

This paper proposes a fuzzy dynamic traffic assignment model taking account of the imprecision and the uncertainties in the route choice process. By modeling the expressions of perceived travel times as fuzzy variables, this model makes possible a more accurate and realistic description of travelers' route choice process than its...

Leveraging Specialty-Contractor Knowledge in Design-Build Organizations

Specialty contractors have knowledge to contribute to the early design of architecture, engineering, and construction AEC products. In current practice, however, they are seldom involved in early design, but evidence suggests that their early involvement is increasing. Lean construction theory advocates such involvement. The practice of involving suppliers in product...
