Urban freight distribution/delivery usually leads to traffic congestion, safety concerns, air pollution, and high logistic costs [1]. In recent years, more and more carriers and shippers have recognized the importance of designing efficient distribution strategies to improve the level of customers service and reduce the financial and environmental cost of freight transportation [2]. However, the extensive literature on the classical vehicle routing problem (VRP) and its variants have primarily considered the problem using static traffic information with corresponding constant travel times. In recent years, a number of studies take account of substantial variation in speeds and improve the model by taking the time dependency of travel times into consideration (see details in Section 2). However, in urban transportation system, lots of random factors, such as uncertain traffic volume, severe weather conditions, and incidents, can lead to the uncertainty of travel times during most of the day, especially during the morning and evening peak periods. Those nonrecurrent events can significantly affect the reliability of the transportation system and contribute to a stochastic timedependent (STD) congested transportation network. Urban route designs that ignore these significant variations and uncertainties of travel times are often found to be inefficient within a congested traffic condition and may contribute to higher operational costs or inferior customer service [1]. Therefore, in order to optimize the freight distribution performance in urban settings, both the random and timevarying properties of the link travel times must be considered. In this paper, we refer to the stochastic time-dependent VRP with hard time window (STDVRPTW). The aim of this study is to devise good and computationally efficient approaches to assist the fleet dispatchers operating in an urban congested environment. To utilize available resources for serve timesensitive customers, this paper takes into consideration of the following travel-time properties:(1)for certain routes, the travel times vary according to the time of day; (2) the travel time is stochastic
