Supply Chain Simulation


Book Description

Supply Chain Simulation allows readers to practice modeling and simulating a multi-level supply chain. The chapters are a combination of the practical and the theoretical, covering: knowledge of simulation methods and techniques, the conceptual framework of a typical supply chain, the main concepts of system dynamics, and a set of practice problems with their corresponding solutions. The problem set includes illustrations and graphs relating to the simulation results of the Vensim® program, the main code of which is also provided. The examples used are a valuable simulation tool that can be modified and extended according to user requirements. The objective of Supply Chain Simulation is to meet the demands of supply chain simulation or similar courses taught at the postgraduate level. The “what if” analysis recreates different simulation scenarios to improve the decision-making process in terms of supply chain performance, making the book useful not only for postgraduate students, but also for industrial practitioners.




Simulation-Based Case Studies in Logistics


Book Description

“Simulation-based Case Studies in Logistics” presents an intensive learning course on the application of simulation as a decision support tool to tackle complex logistic problems. The book describes and illustrates different approaches to developing simulation models at the right abstraction level to be used efficiently by engineers when dealing with strategic, tactical or operational decisions in logistic systems. 11 simulation-based case studies in logistics and supply chain management are discussed, based on the results of applied research, covering application areas such as production logistics, warehousing, transportation, material flow management, and hospital logistics. “Simulation-based Case Studies in Logistics” is an essential text for postgraduate engineering students and researchers working in the area of logistics modeling and simulation.




Simulation Model of Logistics System


Book Description

The goal of the article is to research the information exchange speed's influence on the effectiveness of the organization. It is necessary to model the entire work of the logistic system in order to study the influence of the information flow. This includes raw materials supply, product manufacture, distribution on the market and selling to the end customers. The model should include all three flows that are characteristic of logistic chains: material, cash flow and information. This would allow observing its functioning in its integrity. Besides, basic indicators of effective functioning of such type of systems are the profit realized in the separate chain elements and the number of unsatisfied customers, i.e. the profits foregone. The aim of the model is, setting different values for information exchange and procession speed, to observe the changes in the system's indicators the way they were mentioned above. The relevant conclusions would be made on the base of the received results. All the other system's parameters would have the same values within the planned numeral experiments.




Simulation of Warehousing and Distribution Systems


Book Description

The modern world abounds in simulation models. Thousands of organizations use simulation models to solve business problems. Problems in micro logistics systems are a very important segment of the business problems that can be solved by a simulation method. In most cases logistics simulation models should be developed with a purpose to evaluate the performance of individual value-adding indirect resources of logistics system, their possibilities and operational advantages as well as the flow of logistics entities between the plants, warehouses, and customers. Accordingly, this scientific paper elaborates concisely the theoretical characteristics of simulation models and the domains in which the simulation approach is best suited in logistics. Special attention is paid to simulation modeling of warehousing and distribution subsystems of logistic system and there is an example of spreadsheet application in the function of simulated demand for goods from warehouse. Apart from simulation model induction and deduction methods, the description method and a method of information modeling are applied.




Process Simulation and Optimization in Sustainable Logistics and Manufacturing


Book Description

The aim of this book is to present qualitative aspects of logistics operations and supply chain management which help to implement the sustainable policy principles in the companies and public sector’s institutions. Authors in individual chapters address the issues related to reverse network configuration, forward and reverse supply chain integration, CO2 reduction in transportation, improvement of the production operations and management of the recovery activities. Some best practices from different countries and industries are presented. This book will be valuable to both academics and practitioners wishing to deepen their knowledge in the field of logistics operations and management with regard to sustainability issues.







Modeling, Simulation, and Optimization of Supply Chains


Book Description

This book offers a state-of-the-art introduction to the mathematical theory of supply chain networks, focusing on those described by partial differential equations. The authors discuss modeling of complex supply networks as well as their mathematical theory, explore modeling, simulation, and optimization of some of the discussed models, and present analytical and numerical results on optimization problems. Real-world examples are given to demonstrate the applicability of the presented approaches. Graduate students and researchers who are interested in the theory of supply chain networks described by partial differential equations will find this book useful. It can also be used in advanced graduate-level courses on modeling of physical phenomena as well as introductory courses on supply chain theory.




The Advanced Logistics System CYBER 73: A Simulation Model


Book Description

In support of a request from the Air Force Logistics Command, a model of the Advanced Logistics System (ALS) CYBER 73 Batch processing system was developed. The initial specification required that this model allow changes to the magnetic tape unit configuration and to all essential installation parameters. In order to determine the best approach, the various computer system modeling techniques are first surveyed. Then, based on the modeling goals and requirements, a queue level simulation model is selected as the best approach. The basic features of the CYBER 73 computer system are discussed and a description of job movement through the system is given. This discussion is used to describe the various system queues and the SCOPE integrated scheduler. The algorithms used in the model are then developed and the accuracy of the model verified by comparison against data obtained from the ALS CYBER 73 batch system during test runs of a typical jobmix. The verification process showed that all of the original design objectives were met, although several areas of possible improvement to the model are indicated and discussed.







Simulation for Supply Chain Management


Book Description

This book provides a detailed insight into the simulation approaches employed in the study of supply chain management and control. It begins by examining the types of simulation models (continuous simulation, discrete-event systems and simulation games) before moving on to the distribution levels of systems and models. It concludes with a thorough discussion of simulation products. Simulation methodologies and techniques are also covered throughout the text and case studies are included to highlight the pivotal role played by simulation in the decision-making processes of those working in this field.
