Advanced Planning in Supply Chains

Advanced Planning in Supply Chains



Advanced Planning Systems (APS) are a key enabler of the supply chain management. However, APS are highly complex and difficult to comprehend. This book provides students with valuable insights into the capabilities of state-of-the-art APS and bridges the gap between theory (model building and solution algorithms), software implementation, and adaptation to a specific business case. Our business case named Frutado provides a unifying framework for illustrating the different planning tasks that arise in a company from demand planning to the distribution of goods that are addressed by APS. In addition, the book guides through interactive learning units which have been created and recorded for each module of SAPs APS. Learning units can be downloaded free of charge ready to be displayed in a web browser. Together, the textbook and the learning units provide the required skills to better understand the concepts, models, and algorithms underlying todays APS.




Decision-Making for Supply Chain Integration

Decision-Making for Supply Chain Integration



Effective supply chain integration, and the tight co-ordination it creates, is an essential pre-requisite for successful supply chain management. Decision-Making for Supply Chain Integration is a practical reference on recent research in the area of supply chain integration focusing on distributed decision-making problems. Recent applications of various decision-making tools for integrating supply chains are covered including chapters focusing on: Supplier selection, pricing strategy and inventory decisions in multi-level supply chains, RFID-enabled distributed decision-making, Operational risk issues and time-critical decision-making for sensitive logistics nodes, Modelling end to end processes to improve supply chain integration, and Integrated systems to improve service delivery and optimize resource use.Decision-Making for Supply Chain Integration provides an insight into the tools and methodologies of this field with support from real-life case studies demonstrating successful application of various decision-making techniques. By covering such a range of topics in this way, Decision-Making for Supply Chain Integration is a useful reference for researchers looking to develop their knowledge or find potential new avenues of research.

Fuzzy Probabilities New Approach and Applications

Fuzzy Probabilities New Approach and Applications



In probability and statistics we often have to estimate probabilities and parameters in probability distributions using a random sample. Instead of using a point estimate calculated from the data we propose using fuzzy numbers which are constructed from a set of confidence intervals. In probability calculations we apply constrained fuzzy arithmetic because probabilities must add to one. Fuzzy random variables have fuzzy distributions. A fuzzy normal random variable has the normal distribution with fuzzy number mean and variance. Applications are to queuing theory, Markov chains, inventory control, decision theory and reliability theory.




Random Perturbation Methods with Applications in Science and Engineering, Volume 150

Random Perturbation Methods with Applications in Science and Engineering, Volume 150



As systems evolve, they are subjected to random operating environments. In addition, random errors occur in measurements of their outputs and in their design and fabrication where tolerances are not precisely met. This book develops methods for describing random dynamical systems, and it illustrates how the methods can be used in a variety of applications. The first half of the book concentrates on finding approximations to random processes using the methodologies of probability theory. The second half of the book derives approximations to solutions of various problems in mechanics, electronic circuits, population biology, and genetics. In each example, the underlying physical or biological phenomenon is described in terms of nonrandom models taken from the literature, and the impact of random noise on the solutions is investigated. The mathematical problems in these applicitons involve random pertubations of gradient systems, Hamiltonian systems, toroidal flows, Markov chains, difference equations, filters, and nonlinear renewal equations. The models are analyzed using the approximation methods described here and are visualized using MATLAB-based computer simulations.

Advanced Oil Crop Biorefineries

Advanced Oil Crop Biorefineries



In Europe, the main oil-rich crops are sunflower, rapeseed and olive which are grown primarily for food. This book discusses how to convert this whole crop into energy (fuels, power and heat), food and bioproducts (chemicals and/or materials), whilst making optimal use of the by-products generated during farming/harvesting, primary processing (oil extraction and refining) and secondary processing (transesterification). The resulting processes are more economically competitive and the business margin for oil and biodiesel manufacturers is improved. Previously, oil crops have been the main point of focus but many of the technologies used are applicable to a wide variety of raw materials. For example, cellulose from rapeseed straw can be converted to levulinic acid but the same technology could be applied to cellulose from wheat straw or wood. Significant effort is now being devoted to ‘2nd generation’ raw materials such as ligno-cellulose which avoid direct competition with food sources. This volume integrates these developments with existing plant oil supply chains and combines biochemical and thermochemical processes to form integrated biorefinery schemes. Two unique features of the book are the information on LCA of biorefinery schemes and the surveys showing where traditional industries could be affected by new biorefinery developments. Energy and cost calculations for the key biorefinery processes and are also included revealing that some are surprisingly profitable and could offer significant global benefits. Other topics covered include: novel farming and harvesting methods, efficient extraction of plant oils, producing biodiesel without glycerol, extraction of high value chemicals from agricultural by-products, anaerobic digestion potential of agricultural by-products, use of proteins to yield amino acids, economics and life cycle analysis, stakeholder surveys, and policy scenarios. The book is of interest to academics working in relevant areas of chemistry, biology, materials, engineering, economics and policy studies. Those working in the EU farming industry will also find it relevant to their business.
