Using a sample-based representation scheme to capture spatial and temporal travel time correlations, this article constructs an integer programming model for finding the a priori least expected time paths. We explicitly consider the non-anticipativity constraint associated with the a priori path...

Using a space–time network to represent the choice of train trajectories, this paper proposes a fuzzy optimization framework to reschedule trains in a double-track railway network when the capacity reduction is caused by a low-probability incident. We explicitly introduce a fuzzy...

This paper presents an improved simulation method for solving the train scheduling problem to reduce the total travel time on the single-track railway. An algorithm based on the global information of the train is designed to obtain a more effective travel advance strategy of the train than the...

Focusing on solving critically important train operation problems on a railway network, this paper investigates a mathematical model for finding optimal trains movements under the consideration of operational interactions. With the predetermined routing and traversing order plan, we explicitly...

<title>Abstract</title> Railway traffic experiences disturbances during operations that cause conflicts between train paths or even deadlock situations. Dispatchers need actions to restore feasibility and limit spreading of delays through the network. To help them in such a task, the dispatching support tool...

This paper addresses the problem of train conflict detection and resolution, which is dealt every day by traffic controllers to adapt the timetable to delays and other unpredictable events occurring in real-time. We describe a number of algorithmic improvements implemented in the real-time...

We provide new empirical evidence concerning the contentious debate over the use of historical cost (HCA) versus mark-to-market (MTM) accounting in regulating financial institutions. These accounting rules, through their interactions with capital regulations, alter financial institutions’...

type="main" xml:id="ecop12030-abs-0001" <title type="main">Summary</title> <p>One of the most contentious issues raised during the recent crisis has been the potentially exacerbating role played by mark-to-market accounting. Many have proposed the use of historical cost accounting, promoting its ability to avoid the...</p>

type="main" <title type="main">ABSTRACT</title> <p>We analyze why firms use nonintermediated short-term debt by studying the commercial paper (CP) market. Using a comprehensive database of CP issuers and issuance activity, we show that firms use CP to provide start-up financing for capital investment. Firms’ CP issuance is...</p>
