Modellierung von Kommunikationsprozessen in KMU-Netzwerken: Grundlagen und Ansätze

Kleine und mittlere Unternehmen haben eine enorme Bedeutung für die Entwicklung sowohl der deutschen als auch der europäischen Wirtschaft. Zur Sicherung ihrer Wettbewerbs- und Zukunftsfähigkeit bei sich ständig verändernden Marktbedingungen versuchen viele KMU, ihre betriebliche Entwicklung durch Kooperationen mit anderen Unternehmen zu verbessern. Die dabei entstehenden Unternehmensnetzwerke müssen wachsen und aus sich heraus ihr Fortbestehen sichern, um die Vorteile einer Kooperation nachhaltig zu nutzen. Insofern kommt den Kommunikationsprozessen zwischen vernetzt agierenden Unternehmen eine besondere Bedeutung zu. Umso verwunderlicher ist es, dass man sich bei der Vernetzung von Unternehmen zwar sehr intensiv der Gestaltung der materiellen und informationstechnischen Prozesse widmet, aber die Kommunikation aus den Betrachtungen solcher Netze weitgehend eliminiert. Die Bedeutung der Kommunikation wird nicht unterschätzt. Es kommt aber dem Autor der vorliegenden Arbeit zu, mit einem neuartigen wissenschaftlichen Ansatz eine Methode entwickelt zu haben, um genau diese Prozesse modellieren zu können. Vor diesem Hintergrund erfolgt eine systematische Analyse verschiedenster Kommunikationstheorien und -modelle, in deren Ergebnis einerseits der Begriff der Kommunikationsartefakte eingeführt wird und andererseits eine Vielzahl von Kommunikationsartefakten als potenzielle Modellierungselemente für kommunikative Aspekte beschrieben werden. Damit ist der Versuch, im Rahmen einer ingenie- wissenschaftlichen Arbeit die erkenntnistheoretischen Grundlagen der analysierten Kommunikationstheorien und -modelle zu diskutieren, mit nötigem Respekt gelungen. Bei der Auswahl einer Basismodellierungsmethode gelang es, einen umfassenden Überblick über bekannte Methoden und Sprachen der Geschäftsprozessmodellierung zu geben. Besonders hervorzuheben ist die zusammenfassende Darstellung und Würdigung von Merkmalen und Eigenschaften in Matrizen, die systematisch dazu führt, UML als Basismodellierungsmethode zu begründen.

Modelling Aging and Migration Effects on Spatial Labor Markets (Advances in Spatial Science)

The aging and migration megatrends and their impact on spatial – regional and local – labor market performance is the core theme of this book, and thus together define its scope and focus. The contributions provide an overview of key aging and migration issues in various countries together with analyses of their varied impacts on regional labor markets. Systematic database research and related empirical analyses are used to map out the complex and dynamic nature of these trends, while cutting-edge economic and modeling techniques are used to analyze them. In closing, the book critically reviews and assesses selected policy measures designed to cope with the effects of aging and migration on regional labor markets.

Modelling, Analysis and Optimization of Biosystems

In general, several mathematical models can be designed in order to describe a biological or medical process and there is no unique criterion which model gives the best description. This book presents several of these models and shows applications of them to different biological and medical problems. The book shows that operations research expertise is necessary in respect to modeling, analysis and optimization of biosystems.

Modelling and Decisions in Economics: Essays in Honor of Franz Ferschl

Franz Ferschl is seventy. According to his birth certificate it is true, but it is unbelievable. Two of the three editors remembers very well the Golden Age of Operations Research at Bonn when Franz Ferschl worked together with Wilhelm Krelle, Martin Beckmann and Horst Albach. The importance of this fruitful cooperation is reflected by the fact that half of the contributors to this book were strongly influenced by Franz Ferschl and his colleagues at the University of Bonn. Clearly, Franz Ferschl left his traces at all the other places of his professional activities, in Vienna and Munich. This is demonstrated by the present volume as well. Born in 1929 in the Upper-Austrian Miihlviertel, his scientific education brought him to Vienna where he studied mathematics. In his early years he was attracted by Statistics and Operations Research. During his employment at the Osterreichische Bundeskammer fUr Gewerbliche Wirtschaft in Vienna he prepared his famous book on queueing theory and stochastic processes in economics. This work has been achieved during his scarce time left by his duties at the Bundeskammer, mostly between 6 a.m. and midnight. All those troubles were, however, soon rewarded by the chair of statistics at Bonn University. As a real Austrian, the amenities of the Rhineland could not prevent him from returning to Vienna, where he took the chair of statistics.

Modelling and Empirical Evaluation of Labour Supply Behaviour: Emphasis on Preference Formation, Job Characteristics and Hours Restrictions (Studies in Contemporary Economics)

One of the major issues of policy makers in The Netherlands is to reduce the high unemployment rate. In 1988 economic growth was substantial in all OECD countries, which led to an increase in employment. The economic growth also induced extra labour supply, especially of married women, which altogether led to a smaller reduction in the unemployment rate than could have been expected in view of the economic growth (see Rapportage Arbeidsmarkt, 1989). The estimated official unemployment rate in 1988 is still 11. 0% of the total labour force. Therefore, there is a strong interest in policies that seek to increase employment (the demand side of the labour market) as well as in understanding the factors that influence labour supply. In this thesis we try to further such understanding by constructing a detailed model of household labour supply. The data we use relate t9 Dutch households in 1985. In that year the official rate of unemployment was 15. 9%. A distinguishing feature of Dutch labour supply is its very low level of female labour force participation, e. g. in 1985 it was only 35. 2%. Apart from Spain, which had a similar participation rate, most other industrialized OECD countries had a participation rate of around 60% (see OECD Labor Force Statistics).

Modelling and Evaluating Treatment Effects in Econometrics (Advances in Econometrics #21)

The estimation of the effects of treatments endogenous variables representing everything from individual participation in a training program to national participation in a World Bank loan program has occupied much of the theoretical and applied econometric research literatures in recent years. This volume brings together a diverse collection of papers on this important topic by leaders in the field from around the world. Some of the papers offer new theoretical contributions on various estimation techniques and others provide timely empirical applications illustrating the benefits of these and other methods. All of the papers share two common themes. First, as different estimators estimate different treatment effect parameters, it is vital to know what you are estimating and to know to whom the estimate applies. Second, as different estimators require different identification assumptions, it is crucial to understand the assumptions underlying each estimator. In empirical applications, the researcher must also make the case that the assumptions hold based on the available data and the institutional context. The theoretical contributions range over a variety of different estimators drawn from both statistics and econometrics, including matching and other non-parametric methods, panel methods, instrumental variables, methods based on hazard rate models and principal stratification, and they draw upon both the Bayesian and classical statistical traditions. The empirical contributions focus mainly on the evaluation of active labor market programs in Europe and the United States, but also examine of the effect of parenthood on wages and of the number of children on child health. It contains both theoretical and empirical contributions. It includes examples from both Europe and the US.

Modelling and Forecasting in Dry Bulk Shipping: Modelling And Forecasting In Dry Bulk Shipping (The Grammenos Library)

This book models price behaviour and forecasts prices in the dry bulk shipping market, a major component of the world shipping industry. Recent uncertainties in the world economy, shipbuilding developments and fleet changes mean the dry bulk shipping market has become extremely volatile, highly speculative and more sensitive to external shocks. In response to these challenging circumstances, this book models price behaviour and forecasts prices in various markets including the freight market, the new build ship market and the second-hand ship market. The authors have carried out an extensive investigation of dry bulk shipping over a 60-year period in diverse sub-markets, trading routes, market conditions and dry bulk vessels. The authors also propose a framework for analysing and modelling the economic processes of numerous variables in the dry bulk shipping market, making use of modern econometric techniques and other economic approaches. This will be especially useful for the control and assessment of risk for ship owners and charterers in ship operation, ship chartering and ship trading activities. This book will be extremely useful for shipbuilders, owners and charterers, as well as shipping analysts and policymakers. It will also be of great interest to academics and researchers concerned with the economics of the shipping industry.

Modelling and Intelligent Optimisation of Production Scheduling in VCIM Systems (Springer Theses)

This thesis reports on an innovative production-scheduling model for virtual computer-integrated manufacturing (VCIM) systems. It also describes a robust genetic algorithm for production scheduling in VCIM systems. The model, which is the most comprehensive of its kind to date, is not only capable of supporting collaborative shipment scheduling and handling multiple product orders simultaneously, but also helps cope with multiple objective functions under uncertainties. In turn, the genetic algorithm, characterised by an innovative algorithm structure, chromosome encoding, crossover and mutation, is capable of searching for optimal/suboptimal solutions to the complex optimisation problem in the VCIM production- scheduling model described. Lastly, the effectiveness of the proposed approach is verified in a comprehensive case study.

Modelling Autonomic Communication Environments: 5th IEEE International Workshop, MACE 2010, Niagara Falls, Canada, October 28, 2010, Proceedings (Lecture Notes in Computer Science #6473)

Wearedelightedtopresenttheproceedingsofthe5thInternationalWorkshopon Modeling Autonomic Communication Environments (MACE 2010). This wo- shopwasheldaspartofthe6thInternationalConferenceonNetworkandService Management (CNSM 2010), formerly known as and building on the success of the MANWEEK conference series. This year we met just a hundred yards away from Niagara Falls in Canada, a very exciting location. MACE started as an experiment and over the past years has created a small yet very active community that convened again this year to discuss and ev- uate new advances, innovative ideas, and solid developments. The main focus of MACE, combining modeling with communications, is certainly a hard topic that requires a lot of discussion, thus the work presented at the workshop is - trinsically debatable and might not be as practiced as in other well-established workshops, but this was the nature of MACE from the beginning. New ideas, sometimes more,sometimes less rougharoundthe edges (and someof them even inside) are submitted and provoke extensive discussions. The ?eld in which we areworkingreliesonthesediscussions,orevenadventures,andwehavethis year again strongly motivated and supported a variety of novel work in the technical program. This year, the submissions, while being closely related to the main themes, brought some new areas into the workshop. We still see architectural design and theapplicationofautonomicprinciplestonetworksandservices,butwealsonow have submissions looking into previously unexplored areas such as Home Area Networks,multimedia streaming,virtualization,federation,anduserexperience. This portrays a maturity in the domain, which has by now gone through several cycles, and improves its outputs by applying the lessons learned.
