Download or read book The Concrete Delivery Problem written by Lasse Asbach and published by Peter Lang Pub Incorporated. This book was released on 2008 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: How to deliver, say, 600 vehicle loads of concrete to 200 construction sites with 150 concrete mixer vehicles in order to minimize the costs? When sending where the vehicles can make big differences in costs. Since concrete stays in workable shape only for a certain time inside a vehicle, such concrete delivery problems are subject to constraints, that cannot be found in traditional vehicle routing problems. In this thesis, these logistical problems are analyzed and several models developed. An algorithm based on large neighborhood search is presented, which is capable of solving big real-life instances of such concrete delivery problems heuristically. Although the thesis is mostly concerned with static optimization, issues of and extensions to dynamism and uncertainty are discussed.

Download or read book Failed Stone written by Patrick Loughran and published by Walter de Gruyter. This book was released on 2006-11-21 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete and stone seem made to last forever. But the fact is they develop problems. It is not always as dramatic as the collapse of a section of the roof of the Paris Charles de Gaulle airport in 2004. Gradual changes also occur that may compromise the appearance and structural soundness of buildings constructed with these materials. These changes can be created by efflorescence, thermal stress, weathering, leakage and corrosion. This book explains how to avoid typical kinds of failure. With this in mind, it systematically analyzes cases of damage in contemporary international architecture. It also offers strategies for minimizing the risk of damage. Examples include such high-visibility structures as Finlandia Hall in Helsinki, Parco della Musica in Rome and Vontz Center for Molecular Studies in Cincinnatti. In eight chapters, typical kinds of damage are explained and illustrated with examples. Beton und Stein scheinen für die Ewigkeit gemacht. Dennoch kommt es hier zu Bauschäden. Nicht immer sind sie so dramatisch wie der Deckeneinsturz im Terminal des Flughafen Paris-Roissy 2004. Es gibt auch schleichende Veränderungen, die Erscheinungsbild und Statik von Beton- oder Steingebäuden beeinträchtigen können. Dazu gehören Ausblühungen, thermische Auswirkungen, Materialunverträglichkeiten, Korrosion oder massive Krafteinwirkung. Dieses Buch zeigt, wie sich typische Schäden vermeiden lassen. Zu diesem Zweck analysiert es systematisch Schadensfälle in der zeitgenössischen internationalen Architektur. Ebenso werden Strategien vorgestellt, mit denen sich das Schadensrisiko minimieren lässt. Zu den Beispielen gehören so bekannte Bauten wie die Finlandia Hall in Helsinki, Renzo Pianos Parco della Musica in Rom oder Vontz Center for Molecular Studies in Cincinnatti. In insgesamt acht Kapiteln werden typische Schäden erklärt und dann mit Beispielen illustriert.

Book excerpt: The telephone's insistent ringing at three in the morning snatched Sam Workman from dreamless sleep. "Hello," he mumbled. "This is a warning," said a digitally altered voice. "Leave Betterton now! If you don't, you won't live long enough to regret it." "Who is this?" Sam angrily demanded to a dead line. "Unknown name, unknown number," blinked the call identifier. "Coward!" Workman growled and slammed down the receiver. The call was the first episode in a conspiracy to force Sam and his business, B&W Concrete, out of Betterton or destroy them. Followed were attempts to oust B&W from two construction projects, a hospital addition and an engine plant, totaling $400 million in construction costs to yield B&W $10 million profits. Sam retains attorney Penn Roman to stem the tide of disastrous actions drowning B&W in a flood of claims of incompetency and fraud and more threats and violence against Sam, Penn, and Penn's family. When a testing lab employee working on the projects disappears, and the newspaper prints libelous articles condemning B&W, Penn and Sam find themselves entangled in a web of greed, deceit, violence, and murder. Courageously, they face the schemers in an explosive and telling trial to the finish.
Download or read book Logic Based Benders Decomposition written by John Hooker and published by Springer Nature. This book was released on 2023-12-20 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive guide to logic-based Benders decomposition (LBBD), a general and versatile method for breaking large, complex optimization problems into components that are small enough for practical solution. The author introduces logic-based Benders decomposition for optimization, which substantially generalizes the classical Benders method. It can reduce solution times by orders of magnitude and allows decomposition to be applied to a much wider variety of optimization problems. On the theoretical side, this book provides a full account of inference duality concepts that underlie LBBD, as well as a description of how LBBD can be combined with stochastic and robust optimization, heuristic methods, and decision diagrams. It also clarifies the connection between LBBD and combinatorial Benders cuts for mixed integer programming. On the practical side, it explains how LBBD has been applied to a rapidly growing variety of problem domains. After describing basic theory, this book provides a comprehensive review of the rapidly growing literature that describes these applications, in each case explaining how LBBD is adapted to the problem at hand. In doing so this work provides a sourcebook of ideas for applying LBBD to new problems as they arise.
