This title presents a large variety of models and algorithms dedicated to the resource-constrained project scheduling problem (RCPSP), which aims at scheduling at minimal duration a set of activities subject to precedence constraints and limited resource availabilities. In the first part, the standard variant of RCPSP is presented and analyzed as a combinatorial optimization problem. Constraint programming and integer linear programming formulations are given. Relaxations based on these formulations and also on related scheduling problems are presented. Exact methods and heuristics are surveyed. Computational experiments, aiming at providing an empirical insight on the difficulty of the problem, are provided. The second part of the book focuses on several other variants of the RCPSP and on their solution methods. Each variant takes account of real-life characteristics which are not considered in the standard version, such as possible interruptions of activities, production and consumption of resources, cost-based approaches and uncertainty considerations. The last part presents industrial case studies where the RCPSP plays a central part. Applications are presented in various domains such as assembly shop and rolling ingots production scheduling, project management in information technology companies and instruction scheduling for VLIW processor architectures.

Dienstleistungen werden zunehmend zum zentralen Katalysator innovativer Geschäftsmodelle. Die Charakteristika von Dienstleistungen, wie die Potenzial-, Prozess- und Ergebnisdimension, müssen dabei exante spezifiziert, beschrieben und bewertet werden. Konzepte zur Dienstleistungsmodellierung gewinnen damit prominent an Bedeutung. Diese Entwicklung ist branchenübergreifend in Bewegung, sei es an der Schnittstelle zur industriellen Produktion in Form so genannter Product-Service Systems, im öffentlichen Sektor in Form so genannter Produkt- und Prozessmodelle oder in dienstleistungszentrierten Geschäftsplänen im Umfeld digitaler Geschäftsmodelle und Unternehmensgründungen. Dienstleistungsmodelle werden als Folge zum Dreh- und Angelpunkt für betriebswirtschaftliche Investitionsentscheidungen, ingenieurwissenschaftliche Produktinnovationen und informationstechnische Umsetzungen. Neue Technologien, wie z. B. soziale Netzwerke oder Semantic Web, ermöglichen einerseits eine Steigerung der Produktivität von Dienstleistungen, sie erfordern andererseits jedoch auch leistungsfähige Methoden und Werkzeuge zur Handhabung und Nutzung in der Unternehmenspraxis. Allein das Potenzial in den After-Sales-Bereichen des Maschinenbaus erscheint geradezu unerschöpflich und ermöglicht neue Wertschöpfungskonzepte und -partnerschaften an der Markt- und Kundenschnittstelle. Diesen Herausforderungen und Potenzialen tragen wir durch den vorliegenden Herausgeberband „Dienstleistungsmodellierung 2012 – Product-Service Systems und Produktivität" Rechnung. ​

Project scheduling problems are, generally speaking, the problems of allocating scarce resources over time to perform a given set of activities. The resources are nothing other than the arbitrary means which activities complete for. Also the activities can have a variety of interpretations. Thus, project scheduling problems appear in a large spectrum of real-world situations, and, in consequence, they have been intensively studied for almost fourty years. Almost a decade has passed since the multi-author monograph: R. Slowinski, 1. W~glarz (eds. ), Advances in Project Scheduling, Elsevier, 1989, summarizing the state-of-the-art across project scheduling problems, was published. Since then, considerable progress has been made in all directions of modelling and finding solutions to these problems. Thus, the proposal by Professor Frederick S. Hillier to edit a handbook which reports on the recent advances in the field came at an exceptionally good time and motivated me to accept the challenge. Fortunately, almost all leading experts in the field have accepted my invitation and presented their completely new advances often combined with expository surveys. Thanks to them, the handbook stands a good chance of becoming a key reference point on the current state-of-the-art in project scheduling, as well as on new directions in the area. The contents are divided into four parts. The first one, dealing with classical models -exact algorithms, is preceded by a proposition of the classification scheme for scheduling problems.

Das Buch richtet sich an Dienstleistungsmanager und -planer und beinhaltet ein Kompendium von Modellen, Methoden und Werkzeugen zur Messung, Bewertung undSteuerung der Produktivität von wissensintensiven Dienstleistungen. Neben einermodellbasierten, ganzheitlichen Betrachtung der Produktivität von Dienstleistungenwerden die in empirischen Studien identifizierten Stellgrößen vorgestellt und derenWechselwirkungen in einem System-Dynamics-Modell veranschaulicht. Des Weiteren wirdeine Methode zum partizipativen Projektcontrolling eingeführt. Anhand vonFallbeispielen von international agierenden Unternehmen werden innovative Konzepteund Softwareprototypen demonstriert, mit denen auch schwach strukturierteArbeitsprozesse, wie sie für wissensintensive Dienstleistungen typisch sind,effektiv modelliert, simuliert und optimiert werden können.Die dargestellten Modelle, Methoden und Werkzeuge sollen dem Leser alsUnterstützung dienen, komplexe, wissensintensive Dienstleistungen optimal zuplanen, während der Erbringung erfolgreich zu steuern und abschließend zu bewerten.Als Innovationsführer in verschiedenen wertschöpfungsstarken Branchen istDeutschland insbesondere auf wissensintensive Dienstleistungen dringend angewiesen.Die Wettbewerbsfähigkeit der in diesem Segment tätigen Unternehmen ist beisteigendem Lebensstandard der Beschäftigten und einem latenten Mangel anFachkräften vor allem durch eine Steigerung der Produktivität zu sichern.

This book addresses two of the most difficult and computationally intractable classes of problems: discrete resource constrained scheduling, and discrete-continuous scheduling. The first part of the book discusses problems belonging to the first class, while the second part deals with problems belonging to the second class. Both parts together offer valuable insights into the possibility of implementing modern techniques and tools with a view to obtaining high-quality solutions to practical and, at the same time, computationally difficult problems. It offers a valuable source of information for practitioners dealing with the real-world scheduling problems in industry, management and administration. The authors have been working on the respective problems for the last decade, gaining scientific recognition through publications and active participation in the international scientific conferences, and their results are obtained using population-based methods. Dr E. Ratajczk-Ropel explores multiple agent and A-Team concepts, while Dr A. Skakovski focuses on evolutionary algorithms with a particular focus on the population learning paradigm.

This book presents models and algorithms for complex scheduling problems. Besides resource-constrained project scheduling problems with applications also job-shop problems with flexible machines, transportation or limited buffers are discussed. Discrete optimization methods like linear and integer programming, constraint propagation techniques, shortest path and network flow algorithms, branch-and-bound methods, local search and genetic algorithms, and dynamic programming are presented. They are used in exact or heuristic procedures to solve the introduced complex scheduling problems. Furthermore, methods for calculating lower bounds are described. Most algorithms are formulated in detail and illustrated with examples. In this second edition some errors were corrected, some parts were explained in more detail, and new material has been added. In particular, further generalizations of the RCPSP, additional practical applications and some more algorithms were integrated.

Es zeichnet sich, in der Vermittlung der Grundlagen des OR, durch eine gelungene didaktische Aufbereitung des Stoffes aus und ist auch zum Selbststudium geeignet. Die Autoren beschreiben Verfahren algorithmisch und verdeutlichen sie anhand von aussagekräftigen Beispielen. Der Text behandelt lineare, ganzzahlige und kombinatorische, dynamische sowie nichtlineare Optimierung, Graphen- und Warteschlangentheorie, Netzplantechnik und Simulation. Das Schlusskapitel vermittelt die Lösung von OR-Problemen mittels Tabellenkalkulationssoftware. Zur Vertiefung und Anwendung der vorgestellten Methoden wird das Buch "Übungen und Fallbeispiele zum Operations Research" derselben Autoren empfohlen. Es enthält eine große Anzahl an Übungsaufgaben und eine Einführung in die Optimierung mit Standardsoftware.
