Book Description
Historically multi-item inventory control has been modeled by assuming that each item can be treated independently in a variable cost minimization formulation. In this paper independence between items is not assumed. Constraints on total system operating characteristics create inter-item dependencies. Optimal policies are determined from a goal-constraint formulation. This is done without reliance upon unknown parameters such as order cost and carrying cost which the traditional theory leans on heavily. A group of models are presented, with necessary and sufficient conditions for optimal solutions provided for each. In addition, solution algorithms are indicated for the major models. An algorithm for verification of sufficiency conditions for a non-convex objective function is also provided. (Author).

Book Description
Variations on the traditional cost minimization of continuous review formulation are investigated in an effort to improve service as measured in terms of time-weighted shortages per unit time. It is proposed that the minimization of time-weighted shortages per unit time will improve service in current Navy Supply Operations. Various models are presented, without reliance upon unknown parameters such as order cost and carrying cost, with necessary conditions and solution algorithms. (Author).

Book Description
This report considers a Multi-item (s, S) Inventory System in which shortage costs are replaced by a stockout probability constraint. Necessary and sufficient conditions for a policy to be optimal are derived, and a computational efficient algorithm is developed. Computation experience indicates the operating costs can be reduced significantly. (Author).

Book Description
This book describes the latest advances in intelligent techniques such as fuzzy logic, neural networks, and optimization algorithms, and their relevance in building intelligent information systems in combination with applied mathematics. The authors also outline the applications of these systems in areas like intelligent control and robotics, pattern recognition, medical diagnosis, time series prediction, and optimization of complex problems. By sharing fresh ideas and identifying new targets/problems it offers young researchers and students new directions for their future research. The book is intended for readers from mathematics and computer science, in particular professors and students working on theory and applications of intelligent systems for real-world applications.

Book Description
Constrained multi-item inventory systems with stochastic demands are addressed. The concept of Bad Buys is introduced and their temporal development is studied through a model which links the financial and line-item inventory control subsystems. The interaction of budget constraints and control policies having stochastic resource requirement are examined using a queueing model. Some line-item control systems in current use are shown to be incompatible with budget constrained financial control mechanisms. A model and solution procedure are furnished to guide the line-item inventory control subsystem in exercising adaptive control of a multi-item inventory with stochastic demands and fixed resources provided in successive fiscal periods. An interactive FORTRAN computer program is furnished which exploits the Generalized Lagrange Multiplier procedure in obtaining optimal or near-optimal integer solutions to a class of non-linear integer programming problems.
