Book Description
This paper focuses on a novel approach to cold chain management of perishable products. We extend the classical and frequently applied Economic Order Quantity model (EOQ) for its application in multi-echelon supply chains for highly perishable products. Literature shows that order-level inventory systems for perishable items are commonly modelled by parametric approaches e.g., a time-dependent (Weibull) deterioration rate. However, product deterioration of perishable fresh products is highly product dependent and most of all, both time- and temperature dependent. We take both time-temperature-dependent deterioration and the multi-echelon aspect of cold chains into account and integrate both aspects into a generically applicable EOQ-based methodology.We demonstrate the concept from a real-life case study for cold chain management in floriculture. Two commonly used multi-echelon supply chains for cut roses are considered and compared. The results show that the optimal order levels in different echelons of the supply chains are substantially different. In addition to the sojourn time, the temperature has a major impact on order levels, the total supply chain costs, and the remaining shelf life at the retail level. The proposed concept for extending the EOQ-based model to time- and temperature-dependent deterioration can be easily generalized and applied to other specific causes of product-dependent deterioration.

Book Description
This book deals with inventory systems in supply chains that face risks that could render products unsalable. These risks include possible cooling system failures, transportation risks, packaging errors, handling errors, or natural quality deterioration over time like spoilage of food or blood products. Classical supply chain inventory models do not regard these risks. This thesis introduces novel cost models that consider these risks. It also analyzes how real-time tracking with RFID sensors and smart containers can contribute to decision making. To solve these cost models, this work presents new solution methods based on dynamic programming. In extensive computational studies both with experimental as well as real-life data from large players in the retailer industry, the solution methods prove to lead to substantially lower costs than existing solution methods and heuristics.

Book Description
A perishable item is one that has constant utility up until an expiration date (which may be known or uncertain), at which point the utility drops to zero. This includes many types of packaged foods such as milk, cheese, processed meats, and canned goods. It also includes virtually all pharmaceuticals and photographic film, as well as whole blood supplies. This book is the first devoted solely to perishable inventory systems. The book’s ten chapters first cover the preliminaries of periodic review versus continuous review and look at a one-period newsvendor perishable inventory model. The author moves to the basic multiperiod dynamic model, and then considers the extensions of random lifetime, inclusion of a set-up cost, and multiproduct models of perishables. A chapter on continuous review models looks at one-for-one policies, models with zero lead time, optimal policies with positive lead time, and an alternative approach. Additional chapters present material on approximate order policies, inventory depletion management, and deterministic models, including the basic EOQ model with perishability and the dynamic deterministic model with perishability. Finally, chapters explore decaying inventories, queues with impatient customers, and blood bank inventory control. Anyone researching perishable inventory systems will find much to work with here. Practitioners and consultants will also now have a single well-referenced source of up-to-date information to work with.

Book Description
A consolidation center was established near a set of suppliers with perishable products that have a deterioration rate to consolidate their products and reduce transportation costs. A deterministic demand was considered to solve the model for optimal transportation and holding costs to the suppliers via consolidation center. The products from all suppliers were consolidated at the center to reduce freight transportation costs, which would otherwise have been individually shipped by each supplier. A mixed integer programming (MIP) model was developed to solve the optimal cost of shipping considering the holding cost, transportation cost and deterioration rate. The MIP model was then solved using IBM ILOG CPLEX software. The results of the CPLEX model were compared to new model, which involves decomposition of the original model and using a Lagrangian relaxation heuristic.

The authors depict the reality of this complex world and identify the right strengths, weaknesses, opportunities and threats. Bart Jourquin, European Journal of Transport and Infrastructure Research . . . the editors and the expert contributors provide a timely overview of the present role and challenges of intermodal freight transport. . . the book will not only be appealing to academics and researchers with an interest in the emerging field of intermodal transport research. As the book is largely kept at an executive and policy level, it is also appealing to practitioners and policy makers. . . the book is a valuable contribution to the study of intermodal freight transport as a new transportation research application field. It is an essential reading for all stakeholders in the field of intermodal freight transportation, providing them with insight and tools to address the mounting academic and practical challenges in this segment of the transport and logistics market. Theo Notteboom, Journal of Transport Geography This book explores the great challenge of increasing the scope of intermodal freight transport. In view of the current dominant role of road transport and the increasing difficulties in coping with a growing number of vehicles in an efficient and sustainable way, intermodal freight transport could be considered a viable alternative. However, the book makes recognition of the fact that there is still a need to improve the performance of the intermodal transport system. The expert contributors provide an overview of the present role of intermodal freight transport, address opportunities to significantly improve current performance, and demonstrate design and modelling tools used to analyse and support this performance. Requirements for the implementation of intermodal innovations are also prescribed, and policies needed to improve competitiveness are outlined. Many factors contributing to the performance and competitiveness of intermodal freight transport are explored, from technological and organisational innovations through to institutional settings and policy frameworks. This comprehensive range of topics will attract a broad audience including academics, researchers, policymakers and practitioners involved in the design and development of freight transport systems. It will also strongly appeal to those with an interest in the future of freight transport.
