Chaos and headway distribution of shuttle buses that pass each other freely

Nagatani, Takashi - In: Physica A: Statistical Mechanics and its Applications 323 (2003) C, pp. 686-694

We study the dynamical behavior of a few shuttle buses that pass each other freely on a cyclic route. We present a discrete dynamical model of the shuttle buses to take into account the interactions among buses and passengers. It is found that the bus exhibits a chaotic motion by the free...

Effect of periodic inflow on elevator traffic

Nagatani, Takashi; Tobita, Kazuhiro - In: Physica A: Statistical Mechanics and its Applications 391 (2012) 18, pp. 4397-4405

We study the dynamic behavior of an elevator induced by a periodic inflow of passengers. An elevator schedule is closely related to the dynamics. We present the modified circle map model for the dynamics of the elevator traffic. The motion of the elevator depends on both loading parameter and...

Car attitudes in children from different socio-economic backgrounds in the Netherlands

Kopnina, Helen; Williams, Melanie - In: Transport Policy 24 (2012) C, pp. 118-125

This research explores the attitudes of children from different socio-economic backgrounds towards cars. This paper explores their projected choices and motivations in the context of (1) post-materialist values; (2) economic constraints; and (3) social status theories; and draws upon survey...

Optimal pricing and order quantity for the newsvendor problem with free shipping

Hua, Guowei; Wang, Shouyang; Cheng, T.C.E. - In: International Journal of Production Economics 135 (2012) 1, pp. 162-169

transportation cost into the models. The transportation cost function is very general, which includes those most commonly used in the … literature. We numerically examine the impacts of free shipping, quantity discount, transportation cost, and demand variance on …, and the end customers. An increase in transportation cost or a decrease in purchase price will induce the retailer to …

Column generation based heuristics for a generalized location routing problem with profits arising in space exploration

Ahn, Jaemyung; de Weck, Olivier; Geng, Yue; Klabjan, Diego - In: European Journal of Operational Research 223 (2012) 1, pp. 47-59

The generalized location routing problem with profits is a new routing problem class that combines the vehicle routing problem with profits, depot or base selection, and the notion of strategies and route tactics to be employed at selected bases. The problem simultaneously determines base...

The sample average approximation method for empty container repositioning with uncertainties

Long, Yin; Lee, Loo Hay; Chew, Ek Peng - In: European Journal of Operational Research 222 (2012) 1, pp. 65-75

One of the challenges faced by liner operators today is to effectively operate empty containers in order to meet demand and to reduce inefficiency in an uncertain environment. To incorporate uncertainties in the operations model, we formulate a two-stage stochastic programming model with random...

Real-time freight locomotive rescheduling and uncovered train detection during disruption

Sato, Keisuke; Fukumura, Naoto - In: European Journal of Operational Research 221 (2012) 3, pp. 636-648

This paper discusses rescheduling of freight train locomotives when dealing with a disrupted situation in the daily operations in Japan. Within the current framework of dispatching processes, passenger railway operators modify the entire timetables and an adjusted freight train timetable is...
