In this paper, we give an overview of state-of-the-art Operations Research models and techniques used in passenger railway transportation. For each planning phase (strategic, tactical and operational), we describe the planning problems arising there and discuss some models and algorithms to...

In this paper, we study a decentralized monetary economy with a specified set of markets, rules of trade, an equilibrium concept, and a restricted set of policies and derive a set of equilibrium (monetary) allocations. Next we set up a simpler constrained planning problem in which we restrict...

This paper deals with real-time disruption management of rolling stock in passenger railway transportation. We present a generic framework for modeling disruptions in railway rolling stock schedules. The framework is presented as an online combinatorial decision problem where the uncertainty of...

In the apparel manufacturing process, productivity and quality are somewhat determined by operator skill level. Predicting worker skill level is very important for effective production operation management. However, the current methods for ranking skill level in the manufacturing industry have...

Given a container of fixed width, infinite height and a set of rectangular block, the 2D-strip packing problem consists of orthogonally placing all the rectangles such that the height is minimized. The position is subject to confinement of no overlapping of blocks. The problem is a complex...

This study investigates the revenue performance of choice-based revenue management (RM) systems in various business environments. Previous research conducted using simulated data suggests that incremental revenue gains of up to 15% are to be expected when choice-based RM techniques are employed....

Today, the impact of OR can be felt in many areas. A large number of management firms are currently engaged in OR activities. The principles of operational research (OR) and related mathematical methods have been applied to environmental issues for the long times. However, the increasing...
