Adverse Weather and Commuting Speed
Networks and Spatial Economics - Tập 11 - Trang 701-712 - 2010
This paper investigates the welfare effect of travelling through congested areas and adverse weather through changes in the speed of individuals’ car trips based on the entire commuting trip. Weather measurements are local and time specific (hourly basis). As most commuters travel twice a day between home and work, we are able to employ panel data techniques, which deals with issues related to uno...... hiện toàn bộ
Evacuation Transportation Planning Under Uncertainty: A Robust Optimization Approach
Networks and Spatial Economics - Tập 9 - Trang 171-189 - 2009
This paper considers evacuation via surface transportation networks in an uncertain environment. We focus on demand uncertainty which can lead to significant infeasibility cost during evacuation, where loss of life or property may appear. We develop a robust linear programming model based on a robust optimization approach where hard constraints are guaranteed within an appropriate uncertainty set....... hiện toàn bộ
Drivers' Mental Representation of Travel Time and Departure Time Choice in Uncertain Traffic Network Conditions
Networks and Spatial Economics - Tập 4 - Trang 243-256 - 2004
The decisions drivers make, such as choice of route or departure time, constitute typical decision making under uncertainty. Drivers' decision making has been studied within the framework of expected utility theory. However, empirical decisional phenomena violating the premise of expected utility theory have been observed repeatedly. These findings have indicated that decision making is critically...... hiện toàn bộ
Risk in Transport Investments
Networks and Spatial Economics - Tập 12 - Trang 187-204 - 2009
We discuss how the standard Cost-Benefit Analysis should be modified in order to take risk (and uncertainty) into account. We propose different approaches used in finance (Value at Risk, Conditional Value at Risk, Downside Risk Measures, and Efficiency Ratio) as useful tools to model the impact of risk in project evaluation. After introducing the concepts, we show how they could be used in CBA and...... hiện toàn bộ
Multistage System Planning for Hydrogen Production and Distribution

The Piecewise Constant/Linear Solution for Dynamic User Equilibrium
Networks and Spatial Economics - - 2022
The aim of this work is to increase the precision of the solution of dynamic user equilibrium assuming that the computation takes a reasonable time so that the solution is useful in practice. The proposed method replaces the classical grid-based solution by a near continuous-time solution based on piecewise linear/constant functions that removes a lot of disadvantage of discretization. The testing...... hiện toàn bộ
Planning for Agricultural Forage Harvesters and Trucks: Model, Heuristics, and Case Study
Networks and Spatial Economics - Tập 10 - Trang 321-343 - 2009
In this paper we study an actual problem proposed by an agricultural cooperative devoted to harvesting corn and grass. The cooperative uses harvesters for harvesting the crop and trucks for carrying it from the smallholdings to the landowners’ silos. The goal is to minimize the total working time of the machinery. Therefore, the cooperative needs to plan both the harvesters and trucks routing. Thi...... hiện toàn bộ
Competitive Location and Pricing on Networks with Random Utilities
Networks and Spatial Economics - Tập 16 - Trang 837-863 - 2015
In this paper we analyze the effect of including price competition into a classical (market entrant’s) competitive location problem. The multinomial logit approach is applied to model the decision process of utility maximizing customers. We provide complexity results and show that, given the locations of all facilities, a fixed-point iteration approach that has previously been introduced in the li...... hiện toàn bộ
Các Chính Sách Tham Chiếu cho Thiết Kế Mạng Liên Tục và Vấn Đề Thời Gian Không Ngắn Hạn Dịch bởi AI

Mặc dù có ngày càng nhiều nghiên cứu về tối ưu hóa mạng ngẫu nhiên động, lĩnh vực này vẫn chưa được xác định rõ ràng và thống nhất như các lĩnh vực tối ưu hóa mạng khác. Do nhu cầu sử dụng các phương pháp xấp xỉ như lập trình động xấp xỉ, một trong những vấn đề quan trọng nhất chưa được giải quyết là thiếu các tiêu chuẩn tham chiếu đầy đủ. Các giá trị của chính sách thông tin hoàn hảo và chính sác...... hiện toàn bộ
