Book Description
This book reports the best practices that companies established in Latin America are implementing in their manufacturing processes in order to generate high quality products and stay in the market. It lists the technologies, production and administrative philosophies that are being implemented, presenting a collection of successful cases of studies from Latin America. The book describes how the tools and techniques are being integrated, modified and combined to create new technical resources for assisting the decision making process for better economic performance in manufacturing companies. The efforts deployed for assisting the transformation of raw materials into products and services are described. The authors explain the main key success factors or drivers for success of each tool, technique or hybrid combination approach applied to solve manufacturing problems.

Book Description
Mismatch between supply and demand when the uncertainty of the demand is high and the supply lead time is relatively long such as seasonal good markets can result in high overstocking and understocking costs. In this paper we propose proactive transshipment as a powerful mechanism to mitigate the mismatch between the supply and demand. We consider a finite horizon multi-period inventory system where in each period two retailers have the options to replenish their inventory from a supplier (if there is any supply) or via proactive transshipment from the other retailer. Each retailer observes non-negative stochastic demand with general distribution during the season and incurs overstocking/understocking costs as well as costs for replenishment and transshipment which may be time dependent. We study a stochastic control problem where the objective is to determine the optimal joint replenishment and proactive transshipment policies so as to minimize the total expected cost over the season. We characterize the structure of the optimal policy, and show that, unlike the known order-up-to level inventory policy, the optimal ordering policy in each period is determined based on two switching curves. Similarly, the optimal transshipment policy is also identified by two switching curves. These four curves together partitions the optimal joint ordering and transshipment polices to eight regions where in each region the optimal policy is an order-up-to-curve policy. We demonstrate that the structure of the optimal policy holds for any known sequence and combination of ordering and proactive transshipment over time. We also show that in the optimal policy retailers try to share the risk of the overstocking and understocking costs.

Book Description
These proceedings contain research presented at the 6th International Conference on Dynamics in Logistics, held in February 2018.The integration of dynamics within the modeling, planning and control of logistic processes and networks has shown to contribute massively to the improvement of the latter. Moreover, diversification of markets and demand has increased both the complexity and the dynamic changes of problems within the area of logistics. To cope with these challenges, it must become possible to identify, describe and analyze such process changes. Moreover, logistic processes and networks must be revised to be rapidly and flexibly adaptable to continuously changing conditions. This book presents new ideas to solve such problems, offering technological, algorithmic and conceptual improvements. It primarily addresses researchers and practitioners in the field of industrial engineering and logistics.

Book Description
We study joint replenishment and clearance policy for a perishable product with a general, finite lifetime using a periodic review model over a finite horizon such that the inventory is sold in a last-in, first-out (LIFO) manner. Further, the demand for inventory may depend on its age since customers may choose to walk away if the freshest available inventory is too old for them. The model seeks to optimize two decisions every period: how much of fresh inventory to order and how much of existing inventory to clear. The key objective of the model is to understand the effect of age-dependence of demand on the optimal replenishment and clearance policy.We find that the optimal policy when demand depends on age may diverge substantially from the optimal policy when demand is independent of age, though there exists a sufficient condition under which the structure of the optimal policy becomes identical in both scenarios for all units newer than a threshold age. Further, we show that the structure of the optimal policy for the inventory with one-period remaining lifetime may both simplify and complicate in terms of the number of indexes compared to when demand is independent of age. For the same set of results, we streamline a few arguments for the existing results that are derived assuming demand is independent of age. Finally, we briefly discuss an extension in which clearance is not possible.

Book Description
This book introduces and analyses recent trends and studies of sustainable logistics systems using AI-based meta-heuristics approaches, including AI-based meta-heuristics applied to supply chain network models, integrated multi-criteria decision-making approaches for green supply chain management, uncertain supply chain models etc. It emphasizes both theory and practice, providing methodological and theoretical basis as well as case references for sustainable logistics systems using AI based meta-heuristics. Most of multi-national enterprises today face the challenge of sustainable development for their logistics systems trying to meet or exceed customer expectations. Sustainable development attracts both researchers and industrial practitioners who are focused on the design and implementation of logistics system. AI-based meta-heuristics approaches has emerged as a capable method for quickly providing optimal or near-optimal solutions for the problems that exact optimization cannot solve. Recent advances in various AI-based meta-heuristics approaches can resolve various and complex logistics and supply chain problem types. This book mainly encompasses the most popular and frequently employed AI-based meta-heuristics approaches such as genetic algorithm, variable neighborhood search, multi-objective heuristic search and the hybrid of these approaches. The chapters in this book were originally published in the International Journal of Management Science and Engineering Management.

Book Description
Analytics for the public sector involves the application of operations research and statistical techniques to solve various problems existing outside of the private sector. The use of analytics for the public sector results in more efficient and effective services for the clients and users of these systems. Analytics, Operations, and Strategic Decision Making in the Public Sector is an essential reference source that discusses analytics applications in various public sector organizations, and addresses the difficulties associated with the design and operation of these systems including multiple conflicting objectives, uncertainties and resulting risk, ill-structured nature, combinatorial design aspects, and scale. Featuring research on topics such as analytical modeling techniques, data mining, and statistical analysis, this book is ideally designed for academicians, educators, researchers, students, and public sector professionals including those in local, state, and federal governments; criminal justice systems; healthcare; energy and natural resources; waste management; emergency response; and the military.
