In her book, "Optimization Techniques for Efficient Inventory Systems," S Rajeswari explores various optimization techniques and algorithms that can be used to improve inventory management and supply chain efficiency. The book covers a wide range of topics, including demand forecasting, safety stock, lead time, ordering cost, holding cost, economic order quantity, reorder point, just-in-time, and ABC analysis. One of the key concepts covered in the book is the use of data analysis, machine learning, and artificial intelligence to optimize inventory systems. Rajeswari explains how these technologies can be used to analyze large amounts of data and identify patterns that can be used to improve inventory management. The book also covers a variety of optimization algorithms, including linear programming, nonlinear programming, genetic algorithm, simulated annealing, ant colony optimization, particle swarm optimization, tabu search, variable neighborhood search, and hybrid algorithms. These algorithms can be used to solve complex optimization problems and improve decision-making in inventory management. Other topics covered in the book include multi-objective optimization, Pareto optimization, stochastic optimization, robust optimization, sensitivity analysis, decision-making under uncertainty, risk management, capacity planning, production scheduling, distribution planning, and transportation. Finally, the book explores the concept of green inventory management and sustainable inventory systems. Rajeswari explains how inventory management can be optimized to reduce waste and minimize the environmental impact of inventory systems. Overall, "Optimization Techniques for Efficient Inventory Systems" is a comprehensive guide to inventory management and optimization. It is a must-read for anyone interested in improving their inventory management and supply chain efficiency.
