Abstract

This book presents classical Markov Decision Processes (MDP) for real-life applications and optimization. MDP allows users to develop and formally support approximate and simple decision rules, and this book showcases state-of-the-art applications in which MDP was key to the solution approach. The book is divided into six parts. Part 1 is devoted to the state-of-the-art theoretical foundation of MDP, including approximate methods such as policy improvement, successive approximation and infinite state spaces as well as an instructive chapter on Approximate Dynamic Programming. It then continues with five parts of specific and non-exhaustive application areas. Part 2 covers MDP healthcare applications, which includes different screening procedures, appointment scheduling, ambulance scheduling and blood management. Part 3 explores MDP modeling within transportation. This ranges from public to private transportation, from airports and traffic lights to car parking or charging your electric car. Part 4 contains three chapters that illustrates the structure of approximate policies for production or manufacturing structures. In Part 5, communications is highlighted as an important application area for MDP. It includes Gittins indices, down-to-earth call centers and wireless sensor networks. Finally Part 6 is dedicated to financial modeling, offering an instructive review to account for financial portfolios and derivatives under proportional transactional costs. The MDP applications in this book illustrate a variety of both standard and non-standard aspects of MDP modeling and its practical use. This book should appeal to readers for practitioning, academic research and educational purposes, with a background in, among others, operations research, mathematics, computer science, and industrial engineering.

Abstract

In dem Buch werden zunächst die für eine warteschlangentheoretische Modellierung eines komplexen Inbound Callcenters relevanten Komponenten inklusive ihrer Zusammenhänge und besonderen Eigenschaften beschrieben. Auf dieser Basis werden moderne analytische und simulationsbasierende Methoden zur Analyse der Vorgänge und darauf aufbauend zur Optimierung der Abläufe in einem Callcenter-System vorgestellt. Ziel ist es, dem Planer in einem realen Callcenter Werkzeuge an die Hand zu geben, mit deren Hilfe die Prozesse in Bezug auf Erträge und Kundenzufriedenheit hin verbessert werden können. Es wird dabei versucht, so wenig wie möglich Wissen aus den Bereichen Mathematik und Statistik sowie in Bezug auf den Aufbau eines Callcenters vorauszusetzen. Die notwendigen Statistik-Grundlagen werden als Anhang zur Verfügung gestellt. Des Weiteren werden zu vielen der vorgestellten Analyse- und Optimierungsmethoden Excel-Makros bereitgestellt, um die Methoden direkt auf eigene Daten anwenden zu können. Der Autor Dr. Alexander Herzog, Simulationswissenschaftliches Zentrum Clausthal-Göttingen, Technische Universität Clausthal. Er hat bei großen Unternehmen aus dem Bereich der Telekommunikation, aber auch bei Versicherern und Energieversorgern zur Optimierung der Kundenservice-Bereiche mitgewirkt, dabei ging es um die Analyse der Prozesse, die Implementierung von Simulationstools, sowie um die Schulung der mit der Steuerung der Callcenter betrauten Mitarbeiter.

Abstract

This book provides a complete and comprehensive guide to Pyomo (Python Optimization Modeling Objects) for beginning and advanced modelers, including students at the undergraduate and graduate levels, academic researchers, and practitioners. Using many examples to illustrate the different techniques useful for formulating models, this text beautifully elucidates the breadth of modeling capabilities that are supported by Pyomo and its handling of complex real-world applications. This second edition provides an expanded presentation of Pyomo’s modeling capabilities, providing a broader description of the software that will enable the user to develop and optimize models. Introductory chapters have been revised to extend tutorials; chapters that discuss advanced features now include the new functionalities added to Pyomo since the first edition including generalized disjunctive programming, mathematical programming with equilibrium constraints, and bilevel programming. Pyomo is an open source software package for formulating and solving large-scale optimization problems. The software extends the modeling approach supported by modern AML (Algebraic Modeling Language) tools. Pyomo is a flexible, extensible, and portable AML that is embedded in Python, a full-featured scripting language. Python is a powerful and dynamic programming language that has a very clear, readable syntax and intuitive object orientation. Pyomo includes Python classes for defining sparse sets, parameters, and variables, which can be used to formulate algebraic expressions that define objectives and constraints. Moreover, Pyomo can be used from a command-line interface and within Python's interactive command environment, which makes it easy to create Pyomo models, apply a variety of optimizers, and examine solutions. Review of the first edition: Documents a simple, yet versatile tool for modeling and solving optimization problems. … The book, by Bill Hart, Carl Laird, Jean-Paul Watson, and David Woodruff, is essential to the usability of Pyomo, serving as the Pyomo documentation. … has contents for both an inexperienced user, and a computational operations research expert. … with examples of each of the concepts discussed. —Nedialko B. Dimitrov, INFORMS Journal on Computing, Vol. 24 (4), Fall 2012.

Abstract

Das Buch befasst sich mit der Kalkulation von Baukosten und Bauzeiten für Auftraggeber und Auftragnehmer in verschiedenen Projektphasen. Am Ende jeder Projekt- und Bauwerksanalyse sind möglichst genaue Angaben zu Zeiten, Kosten und Preisen vorzulegen, die in Abhängigkeit von der Komplexität des Bauobjekts und den Umständen der Leistungserbringung auf einer mehr oder weniger unsicheren Datenbasis stehen. Im Zuge einer Bandbreitenbetrachtung von maßgebenden Inputgrößen kann eine ganzheitliche Perspektive eingenommen werden, wodurch insbesondere Unsicherheiten systematisch Eingang in die Analyse finden. Somit kann die Aussagekraft und Validität konkreter Werte erhöht werden. Durch die Wahl der Bezugsbasis (Werte) wird bestimmt, welche Chancen bzw. Risiken eingegangen werden. Erst die Anwendung probabilistischer Methoden erlaubt die Kalkulation und grafische Darstellung des für die Entscheidungsfindung zentralen Chancen-Risikoverhältnisses. Im Fokus der Betrachtungen steht die systematische Berücksichtigung von Unsicherheiten bei der Ermittlung von Baukosten und Bauzeiten sowie der Lebenszykluskosten. Ergänzend dazu erfolgt eine detaillierte Darstellung anderer Entscheidungsprozesse für die Projektvorbereitung und Planung (Developer-Rechnung, Baugrundanalyse, Kostenschätzung etc.), die Ausführungsvorbereitung (Kosten- und Preisermittlung, Bewertung der Bauzeit, Ressourcenermittlung, Verfahrensvergleich, Angebotsanalyse, Vergabeentscheidung etc.) und die Bauwerksrealisierung (Baulogistik, Verfahrensauswahl, Bauablaufplanung, Leistungsabstimmung, Beschaffung, Mehrkostenermittlung, Trendanalyse etc.) sowie für das übergeordnete Projektportfoliomanagement. Der Inhalt § Grundlagen zu Chancen/Risiken und der Monte-Carlo-Methode § Behandlung praxisrelevanter Aspekte der Monte-Carlo-Simulation § Erfassung und Umgang mit Chancen- und Risikopotenzialen § Anwendung der Monte-Carlo-Simulation in Projektmanagement, Baubetrieb und Bauwirtschaft § Berechnung des Chancen-Risikoverhältnisses für zentrale Projektkenngrößen § Neue Perspektiven des quantitativen Chancen-Risikomanagements bezogen auf die Vorbereitung und die Realisierung von Bauwerken § Erhöhung der Transparenz und Sicherheit in der Entscheidungsfindung § Illustrierung des Chancen-Risikomanagementprozesses für den Baubetrieb und die Bauwirtschaft § Verdeutlichung des systematischen Umgangs mit Produktivität und Produktivitätsverlusten § Vermittlung der essenziellen Bedeutung der Projektvorlaufzeit und der Bauzeit für den Projekterfolg § Anwendungsfreundliche Praxisbeispiele für Auftraggeber sowie Auftragnehmer in verschiedenen Projektphasen.

Abstract

This book is an expository introduction to the methodology of sensitivity analysis of model output. It is primarily intended for investigators, students and researchers that are familiar with mathematical models but are less familiar with the techniques for performing their sensitivity analysis. A variety of sensitivity methods have been developed over the years. This monograph helps the analyst in her/his first exploration of this world. The main goal is to foster the recognition of the crucial role of sensitivity analysis methods as the techniques that allow us to gain insights from quantitative models. Also, exercising rigor in performing sensitivity analysis becomes increasingly relevant both to decision makers and modelers. The book helps the analyst in structuring her/his sensitivity analysis quest properly, so as to obtain the correct answer to the corresponding managerial question. The first part of the book covers Deterministic Methods, including Tornado Diagrams; One-Way Sensitivity Analysis; Differentiation-Based Methods and Local Sensitivity Analysis with Constraints. The second part looks at Probabilistic Methods, including Regression-Based methods, Variance-Based Methods, and Distribution-Based methods. The final section looks at Applications, including capital budgeting, sensitivity analysis in climate change modelling and in the risk assessment of a lunar space mission.

Abstract

This book provides a straightforward overview for every researcher interested in stochastic dynamic vehicle routing problems (SDVRPs). The book is written for both the applied researcher looking for suitable solution approaches for particular problems as well as for the theoretical researcher looking for effective and efficient methods of stochastic dynamic optimization and approximate dynamic programming (ADP). To this end, the book contains two parts. In the first part, the general methodology required for modeling and approaching SDVRPs is presented. It presents adapted and new, general anticipatory methods of ADP tailored to the needs of dynamic vehicle routing. Since stochastic dynamic optimization is often complex and may not always be intuitive on first glance, the author accompanies the theoretical ADP-methodology with illustrative examples from the field of SDVRPs. The second part of this book then depicts the application of the theory to a specific SDVRP. The process starts from the real-world application. The author describes a SDVRP with stochastic customer requests often addressed in the literature, and then shows in detail how this problem can be modeled as a Markov decision process and presents several anticipatory solution approaches based on ADP. In an extensive computational study, he shows the advantages of the presented approaches compared to conventional heuristics. To allow deep insights in the functionality of ADP, he presents a comprehensive analysis of the ADP approaches.

Abstract

Facility location theory develops the idea of locating one or more facilities by optimizing suitable criteria such as minimizing transportation cost, or capturing the largest market share. The contributions in this book focus an approach to facility location theory through game theoretical tools highlighting situations where a location decision is faced by several decision makers and leading to a game theoretical framework in non-cooperative and cooperative methods. Models and methods regarding the facility location via game theory are explored and applications are illustrated through economics, engineering, and physics. Mathematicians, engineers, economists and computer scientists working in theory, applications and computational aspects of facility location problems using game theory will find this book useful.
