This book was released on 2019-03-14 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to improve the performance of production systems, companies consider the optimization of the flow line configuration. However, the material supply of the flow line exerts a strong influence on the output of the production system since material shortages impede the flow of workpieces through the flow line. Simultaneously, the configuration of the flow line determines the demand for material. Consequently, the mutual interdependence between the material supply and the flow line has to be considered in order to balance a sufficient material supply of the flow line avoiding material shortages as well as excessive material inventory and handling effort. We provide integrated approaches for the evaluation and optimization of stochastic flow lines with limited material supply. Thereby, we make use of several evaluation methods as Markov chain approaches, aggregation and decomposition approaches as well as linear programming. Further, we model open and closed queuing networks in continuous and discrete time. Hence, we present exact and approximate approaches that allow us to study the effects in several stochastic production systems with limited material supply.
Book Synopsis Using Recurrent Neural Networks for the Performance Analysis and Optimization of Stochastic Milkrun-supplied Flow Lines by : Insa Südbeck
Download or read book Using Recurrent Neural Networks for the Performance Analysis and Optimization of Stochastic Milkrun-supplied Flow Lines written by Insa Südbeck and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term throughput, as a key performance indicator of a stochastic flow line, is affected by numerous parameters describing the features of the flow line, such as processing time and buffer size. Fast and accurate evaluation methods for a given set of values for those parameters are a prerequisite to systematically optimize such a flow line. In this paper, we consider the case of a flow line with random processing times, limited buffer capacities and so-called milkruns that supply the machines with material parts that are required to perform, e.g., assembly operations on workpieces. In such a system, shortages in the supply of material parts can limit the performance of the flow line. Up to now, there are no accurate analytical approaches to quantify the complex interactions in such milkrun-supplied flow lines for realistic problem sizes. We propose to use recurrent neural networks to determine the long-term throughput of such flow lines enabling us to evaluate production systems of flexible size. Our results show that the throughput can be determined accurately and quickly via recurrent neural networks. Furthermore, we use this new evaluation procedure as a building block to optimize this type of flow line using gradient and local search techniques.
Book Synopsis Performance Analysis of Flow Lines with Non-Linear Flow of Material by : Stefan Helber
Download or read book Performance Analysis of Flow Lines with Non-Linear Flow of Material written by Stefan Helber and published by . This book was released on 1999-08-19 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow line design is one of the major tasks in production management. The decision to install a set of machines and buffers is often highly irreversible. It determines both cost and revenue to a large extent. In order to assess the economic impact of any possible flow line design, production rates and inventory levels have to be estimated. These performance measures depend on the allocation of buffers whenever the flow of material is occasionally disrupted, for example due to machine failures or quality problems. The book describes analytical methods that can be used to evaluate flow lines much faster than with simulation techniques. Based on these fast analytical techniques, it is possible to determine a flow line design that maximizes the net present value of the flow line investment. The flow of material through the line may be non-linear, for example due to assembly operations or quality inspections.
Book Synopsis Generalized Bounds for Convex Multistage Stochastic Programs by : Daniel Kuhn
Download or read book Generalized Bounds for Convex Multistage Stochastic Programs written by Daniel Kuhn and published by Springer Science & Business Media. This book was released on 2006-03-30 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work was completed during my tenure as a scientific assistant and d- toral student at the Institute for Operations Research at the University of St. Gallen. During that time, I was involved in several industry projects in the field of power management, on the occasion of which I was repeatedly c- fronted with complex decision problems under uncertainty. Although usually hard to solve, I quickly learned to appreciate the benefit of stochastic progr- ming models and developed a strong interest in their theoretical properties. Motivated both by practical questions and theoretical concerns, I became p- ticularly interested in the art of finding tight bounds on the optimal value of a given model. The present work attempts to make a contribution to this important branch of stochastic optimization theory. In particular, it aims at extending some classical bounding methods to broader problem classes of practical relevance. This book was accepted as a doctoral thesis by the University of St. Gallen in June 2004.1 am particularly indebted to Prof. Dr. Karl Frauendorfer for - pervising my work. I am grateful for his kind support in many respects and the generous freedom I received to pursue my own ideas in research. My gratitude also goes to Prof. Dr. Georg Pflug, who agreed to co-chair the dissertation committee. With pleasure I express my appreciation for his encouragement and continuing interest in my work.
Book Synopsis Strategic Safety Stocks in Supply Chains by : Stefan Minner
Download or read book Strategic Safety Stocks in Supply Chains written by Stefan Minner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing customer requirements, product variety, and market competition demand for service and cost improvements by model based inventory control in supply chains. The book presents approaches for safety stock determination in manufacturing and logistics networks. Most of the existing literature provides methods for very specific types of supply networks. The approach presented in this book follows a material flow philosophy that allows for several extensions of the basic models and therefore offers a wide applicability within decision support systems. Models for several types of problems and network structures are presented and analyzed to develop efficient optimization algorithms and heuristics.
Book Synopsis Lot-Sizing and Scheduling for Flexible Flow Lines by : Daniel Quadt
Download or read book Lot-Sizing and Scheduling for Flexible Flow Lines written by Daniel Quadt and published by Springer Science & Business Media. This book was released on 2012-09-14 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book considers the lot-sizing and scheduling problem for flexible flow line production facilities. Flexible flow lines are flow lines with parallel machines on some or all production stages. They can be found in a vast number of industries. A three-phased solution approach is presented that solves the integrated lot-sizing and scheduling problem in a hierarchical manner. The approach is able to handle several important features relevant in industrial practice, such as back-orders and setup carry-over. The developed solution procedures solve practically sized problems in a relatively short amount of time. One of the procedures is based on a novel mixed integer programming (MIP) model, which employs integer variables instead of binary variables. This makes it possible to find (near-)optimal solutions using standard algorithms such as CPLEX. Another procedure uses two nested Genetic Algorithms. An application of the framework in the semiconductor industry is given.
Book Synopsis Planning Stability in Material Requirements Planning Systems by : Gerald Heisig
Download or read book Planning Stability in Material Requirements Planning Systems written by Gerald Heisig and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: In logistics systems, the issue of planning stability has attracted increased attention and interest in recent years. This is mainly due to an increasing integration of planning systems both within and across companies in supply chain management. The propagation of adjustments in planning systems first acquired wide attention when MRP systems were employed as standard planning tools for material coordination. Within a rolling horizon framework the MRP application produced considerable planning instability which origins from uncertainties in the planner's exogenous environment as well as from endogenous sources. This book presents an analytical investigation that gives deep insight into the influence of different kind of inventory control rules on the stability of material planning systems under stochastic demand in a rolling horizon environment.
Book Synopsis Collaborative Planning in Supply Chains by : Gregor Dudek
Download or read book Collaborative Planning in Supply Chains written by Gregor Dudek and published by Springer Science & Business Media. This book was released on 2004 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book deals with collaborative planning, an approach to supply chain planning which aims to coordinate planning tasks of independent supply chain partners while respecting their local decision authority. The major contribution of this work is to provide a process model concerned with the decision making and negotiation aspects of collaborative planning. Taking technological means for data exchange as a given, it sketches a detailed picture of a collaborative planning process at the medium-term level of master planning, assuming that mathematical programming models are used by all partners. Building on the planning process, it indicates how financial outcomes and partner incentives are affected by the negotiations of supply quantities between buyers and suppliers, and demonstrates how supply contract terms can be adapted in order to establish a win-win situation for all partners.

Book Synopsis Topics in Dynamic Model Analysis by : Mario Faliva
Download or read book Topics in Dynamic Model Analysis written by Mario Faliva and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical econometrics - which plunges its roots in economic theory with simultaneous equations models (SEM) as offshoots - and time series econometrics - which stems from economic data with vector autoregr- sive (VAR) models as offsprings - scour, like the Janus's facing heads, the flowing of economic variables so as to bring to the fore their autonomous and non-autonomous dynamics. It is up to the so-called final form of a dy namic SEM, on the one hand, and to the so-called representation theorems of (unit-root) VAR models, on the other, to provide informative closed form expressions for the trajectories, or time paths, of the economic vari ables of interest. Should we look at the issues just put forward from a mathematical standpoint, the emblematic models of both classical and time series econometrics would turn out to be difference equation systems with ad hoc characteristics, whose solutions are attained via a final form or a represen tation theorem approach. The final form solution - algebraic technicalities apart - arises in the wake of classical difference equation theory, display ing besides a transitory autonomous component, an exogenous one along with a stochastic nuisance term. This follows from a properly defined ma trix function inversion admitting a Taylor expansion in the lag operator be cause of the assumptions regarding the roots of a determinant equation pe culiar to SEM specifications.

Book Synopsis Cooperative Decision Making in Common Pool Situations by : Holger I. Meinhardt
Download or read book Cooperative Decision Making in Common Pool Situations written by Holger I. Meinhardt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The monograph gives a theoretical explanation of observed cooperative behavior in common pool situations. The incentives for cooperative decision making are investigated by means of a cooperative game theoretical framework. In a first step core existence results are worked out. Whereas general core existence results provide us with an answer for mutual cooperation, nothing can be said how strong these incentives and how stable these cooperative agreements are. To clarify these questions the convexity property for common pool TU-games in scrutinized in a second step. It is proved that the convexity property holds for a large subclass of symmetrical as well as asymmetrical cooperative common pool games. Core existence and the convexity results provide us with a theoretical explanation to bridge the gap between the observation in field studies for cooperation and the noncooperative prediction that the common pool resource will be overused and perhaps endangered.
Book Synopsis Unemployment in Open Economies by : Pia Weiß
Download or read book Unemployment in Open Economies written by Pia Weiß and published by Springer Science & Business Media. This book was released on 2000-11-16 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unemployment in Open Economies studies how domestic labour markets are influenced by a changing international environment. It combines the recently developed search and matching models with standard models of international trade. By this method, the reader gains new insights in the ongoing debate on how globalisation can affect unemployment. The author develops a collection of models showing that globalisation can be one reason for long-known and well-documented phenomenons on the labour market. She puts emphasis on country differences by studying the role of individual risk behavior and the wage setting on the unemployment level.

Book Synopsis Default Risk in Bond and Credit Derivatives Markets by : Christoph Benkert
Download or read book Default Risk in Bond and Credit Derivatives Markets written by Christoph Benkert and published by Springer Science & Business Media. This book was released on 2012-08-27 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the scarcity of reliable data, the existing literature on default risk still displays an imbalance between theoretical and empirical contributions. Consequently, the focus of this book is on empirical work. Within an intensity based modelling framework a broad range of promising specifications is tested using corporate bond data. The book provides one of the most comprehensive empirical studies in the field, from Kalman filtration of affine term structure models to the use of Efficient Method of Moments estimation of dynamic term structure models in a default risky context. Filling another gap in empirical research, the book devotes special attention to the identification factors that can explain credit default swap premia.

Book Synopsis Financial Pricing Models in Continuous Time and Kalman Filtering by : B.Philipp Kellerhals
Download or read book Financial Pricing Models in Continuous Time and Kalman Filtering written by B.Philipp Kellerhals and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Straight after its invention in the early sixties, the Kalman filter approach became part of the astronautical guidance system of the Apollo project and therefore received immediate acceptance in the field of electrical engineer ing. This sounds similar to the well known success story of the Black-Scholes model in finance, which has been implemented by the Chicago Board of Op tions Exchange (CBOE) within a few month after its publication in 1973. Recently, the Kalman filter approach has been discovered as a comfortable estimation tool in continuous time finance, bringing together seemingly un related methods from different fields. Dr. B. Philipp Kellerhals contributes to this topic in several respects. Specialized versions of the Kalman filter are developed and implemented for three different continuous time pricing models: A pricing model for closed-end funds, taking advantage from the fact, that the net asset value is observable, a term structure model, where the market price of risk itself is a stochastic variable, and a model for electricity forwards, where the volatility of the price process is stochastic. Beside the fact that these three models can be treated independently, the book as a whole gives the interested reader a comprehensive account of the requirements and capabilities of the Kalman filter applied to finance models. While the first model uses a linear version of the filter, the second model using LIBOR and swap market data requires an extended Kalman filter. Finally, the third model leads to a non-linear transition equation of the filter algorithm.
