Available in PDF, EPUB and Kindle. Book excerpt: The report studies inventory systems in which the stock records are in error. The overall goal is to determine economically the proper level of stock record accuracy to maintain, consistent with insuring that the remaining errors do not contribute significantly to warehouse denials, i.e., phenomena in which the stock records show a balance sufficient to cover a material release order, but for which insufficient units of physical stock can be found. The factors considered in addition to the statistics of the errors, are the costs and movement of the items and the costs and accuracies of the various types of counting procedures available. The approach taken determines the type and frequency of the counts, together with the modifications to a predetermined stocking policy, to insure, at minimum total cost per unit time, that the likelihood of a warehouse denial occurring between counts is held below some prescribed level.

Book excerpt: We study inventory systems operating under an infinite-horizon, periodic-review base-stock control policy with stochastic demand and imperfect (i.e., less than 100% reliable) supply. We model demand using a general discrete distribution and replenishment lead time using a geometric distribution, resulting from a Bernoulli trial-based model of supply uncertainty. We develop a computational approach using a discrete time Markov process (DTMP) model to minimize the total system cost and obtain the optimal base-stock level when the backorder penalty is given. We develop a general, recursive solution for the steady state probability of each inventory level and use this to find the optimal base-stock level in this setting. Moreover, for specific demand distributions we are able to develop closed-form solutions for these outcomes. The lead-time demand (LTD) distribution can also be obtained from these recursive equations to determine the base-stock level when a target customer service level is specified in lieu of a backorder penalty cost. We conduct extensive computational experiments to observe the robustness of various approximate solutions under two scenarios for the lead-time distribution. The first scenario assumes a geometric lead time. The second scenario considers a general lead-time distribution. We conduct computational experiments to observe the conditions in which the DTMP model performs well, including situations where the demand and the lead-time distributions are specified separately, and where the LTD distribution is given and follows either a Beta distribution or a bimodal distribution. Finally, for a two-location inventory system consisting of a single retailer supplied by a single distributor, whose supply ultimately comes from an unreliable supplier upstream, we propose a computational approach to determine optimal or near-optimal base-stock levels at the retailer and distributor. We develop two decomposition-based approximation methods, solving the se.
Download or read book Optimization and Inventory Management written by Nita H. Shah and published by Springer Nature. This book was released on 2019-08-31 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses inventory models for determining optimal ordering policies using various optimization techniques, genetic algorithms, and data mining concepts. It also provides sensitivity analyses for the models’ robustness. It presents a collection of mathematical models that deal with real industry scenarios. All mathematical model solutions are provided with the help of various optimization techniques to determine optimal ordering policy. The book offers a range of perspectives on the implementation of optimization techniques, inflation, trade credit financing, fuzzy systems, human error, learning in production, inspection, green supply chains, closed supply chains, reworks, game theory approaches, genetic algorithms, and data mining, as well as research on big data applications for inventory management and control. Starting from deterministic inventory models, the book moves towards advanced inventory models. The content is divided into eight major sections: inventory control and management – inventory models with trade credit financing for imperfect quality items; environmental impact on ordering policies; impact of learning on the supply chain models; EOQ models considering warehousing; optimal ordering policies with data mining and PSO techniques; supply chain models in fuzzy environments; optimal production models for multi-items and multi-retailers; and a marketing model to understand buying behaviour. Given its scope, the book offers a valuable resource for practitioners, instructors, students and researchers alike. It also offers essential insights to help retailers/managers improve business functions and make more accurate and realistic decisions.
Download or read book Inventory Systems with Imperfect Demand Information written by Richard C. Morey and published by . This book was released on 1969 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report studies inventory systems in which demand information can be incorrectly transmitted from the field to the stockpoint. Keypunching errors and improper preparation of requisitions are examples of the types of causes that may give rise to such a situation. The main effect of such errors is that supply points may process demands which are considerably different than the true demands, and hence increase the total systems operating cost. A study of the increased cost as a function of the variability of the errors is necessary to determine the amount and direction of effort that should be spent to deal with them. Two main types of analyses are presented. The first is a dynamic programming approach which determines the optimal ordering procedure for the general n period problem. A second approach has used a steady state analysis to assess the dollar impact of the errors. (Author).
