The aim of this study is to identify factors that improve the performance of integrated supply chains (SCs). We developed the ‘extended strategic alignment model’ based on the literature on next generation supply chains, supply chain management, and the role of IT and business architectures. The model was used to do in depth analysis of the Unitech worldwide SC for high-tech handheld scanning d...

We formulate an empirical model of congestion for a network where queues may form and spill back from one link to another. Its purpose is to disentangle the dynamic effect that a marginal vehicle, on a given link and at a given time, has on the distribution of travel times experienced there and on connected links. We estimate a dynamic model, based on an unusually complete and accurate dataset ...

We consider an industry where a downstream competitor requires access to an upstream facility controlled by a vertically integrated and regulated incumbent. The literature on access pricing assumes the access price to be exogenously ...xed ex-ante. We analyze an endogenous average cost based access pricing rule, where both ...rms realize the interdependence among their quantities and the regula...

How quickly do different kinds of conceptual knowledge become available following visual word perception? Resolving this question will inform neural and computational theories of visual word recognition and semantic memory use. We measured real-time brain activity using event-related brain potentials (ERPs) during a go/nogo task to determine the upper limit by which category-related knowledge (...

This paper presents a new short-term traffic flow prediction system based on an advanced Time Delay Neural Network (TDNN) model, the structure of which is synthesized using a Genetic Algorithm (GA). The model predicts flow and occupancy values at a given freeway section based on contributions from their recent temporal profile (over a few minutes) as well the spatial profile (including inputs f...

Software ecosystem platforms such as Google’s Play Store or Apple’s App Store rely heavily on highly motivated third-party developers who are eager to invest their time and effort into developing and updating apps for platforms. Platform owners are challenged to find a balance between developers’ need for autonomy and a platform’s integrity. Despite the widely acknowledged importance of informa...

Mintek, specialists in mineral and metallurgical technology, have developed advanced optimisation control strategies in milling, flotation and smelting. The strategies address process specific problems namely downstream flow disturbances in flotation circuits from open milling circuits, fluctuating grade and recovery of flotation circuits and furnace fault conditions including power trips and e...

In this paper, we describe a pilot implementation and field test of a recently developed approach to real-time adaptive traffic signal control. The pilot system, called SURTRAC (Scalable Urban Traffic Control), follows the perspective of recent work in multi-agent planning and implements a decentralized, schedule-driven approach to traffic signal control. Under this approach, each intersection ...
