- ItemSOLUTION APPROACHES TO THE BUS OPERATOR PROBLEM(PERGAMON-ELSEVIER SCIENCE LTD, 1993) Fernandez, J.E.; Marcotte, P.; Mondschein, S.; Vera, J.; Weintraub, A.We study urban traffic equilibrium involving three classes of agents: car users, bus users or passengers and bus operators. A partially unregulated transit system is assumed, where bus fares are exogenously determined by municipal or transportation authorities, but bus operators are allowed to choose the routes where they offer service. The paper deals specifically with the bus operators submodel, for which several algorithms are proposed to find equilibrium solutions. Convergence properties of the proposed algorithms are analyzed and computational results, on both small test networks and the Santiago de Chile urban transit network, are reported. Various methods to deal with the problem posed by limited bus capacities are discussed.
- ItemTrends and predictors of birth weight in Chilean children(2021) Garmendia, M. L.; Mondschein, S.; Montiel, B.; Kusanovic, J. P.Objectives: Birth weight is an important public health indicator that reflects fetal health conditions and predicts future health. Identifying the most important factors related to birth weight would help defining preventive health strategies for both mothers and children. The objectives of this study are i. to describe, using a large birth database from a Chilean hospital, the trend of birth weight during 2002-2015, and ii. to determine factors during prenatal care associated with low and high birth weight.
