Purpose – Ensuring the sufficient service level is essential for critical materials in industrial maintenance. This study aims to evaluate the use of statistically imperfect data in a stochastic simulation-based inventory optimization where items' failure characteristics are derived from...

Purpose – The paper has two main aims: to focus on how the spare parts optimization process was conducted in the Norwegian Defence procurement projects that had used the system approach based on OPUS10, and whether coordination issues affected the process and results; and to analyse empirical...

The work deals with the topic of spare parts management in a space system. The paper is divided into three parts. The first one is dedicated to the characterization of the system structure and presents the particularities related to the spare‐elements procurement. Modelling is the object of...

Purpose – The ongoing availability of existing industrial systems/machines depends to a great extent on the form and level of product support. Product support, or the after sale service of a product, is important because it assures the expected function of the product in its operational phase....

“Insurance type” spares are spares for critical parts which are essential for the operation of the system in which they serve, and which have an appreciable probability of not needing replacement during the lifetime of the system. Owing to their nature, the ( S ‐1, S ) inventory control...

Purpose – Spare parts have become ubiquitous in modern societies and managing their requirements is an important and challenging task with tremendous cost implications for the organisations that are holding relevant inventories. An important operational issue involved in the management of...

A new policy for joint optimization of age replacement and spare provisioning has been proposed by incorporating a continuous review ( s, S ) type inventory policy, where s is the reorder level and S is the maximum stock level. Gives cost formulations for a single operating unit situation and...

Analyses the system of work in the maintenance departments of 59 Saudi industries and services. The sample includes 13 manufacturing, 12 metals, nine chemical and 25 other industries and services. The data were collected by a specially designed survey. Results show that maintenance departments...

Notes, in recent years, an increase of interest in the field of service parts inventory ‐ particularly in the computer industry. Explains that the computer industry is a highly competitive industry; products have to be repaired as quickly as possible, since slow repair can lead to loss of...

Service parts are needed for maintenance of industrial systems as well as for consumer products. Their logistics has an inherent difficulty: common models for inventory management are invalid, as the demand process is different and demand data scarce. The paper discusses experiences gained in...
