Original scientific paper A distinctive characteristic of the spare parts inventory system is the need to evaluate or define the criticality of items in the inventory. Therefore, there is a need to consider factors such as cost, failure rate and availability, among others. There are few papers in literature that discuss relevant methods to define a reliable hierarchy of a set of spare parts. Up...

The after-sales services and in particular the spare parts business have acquired, in recent years, a strategic role for firms manufacturing durable or capital goods, as they represent a source of revenue, profit and a mean to achieve customer satisfaction and retention. Nonetheless, the huge variety and the characteristics of the demand of spare parts make the configuration and management of t...

The maintenance of complex capital goods wins more and more in importance. This article will describe a method to raise a condition prognostication of modules and spare parts and the corresponding order probabilities of spare parts during the tear down process. It will give an overview how uncertainty can be represented by the use of probabilities. The consideration of different factors of infl...

Supplier evaluation is an important problem in industrial management. An accurate evaluation can reduce the costs and increase the quality of products. There are various studies for evaluation of suppliers. However, this problem has been complicated by uncertain data and multiple criteria. In this study we develop a Fuzzy Inference System (FIS) to deal with uncertain data and evaluate suppliers...

Network survivability gauges the ability of a network to support the committed Quality of Services (QoS) continuously in the presence of various failure scenarios. MPLS Mesh-Based network can be used to provide network survivability in case of link and node failure through predesign path protection techniques. In the Preplanned self-healing networks, we have to provision adequate spare capacity...

Objective: To investigate the significance of intrafascial neurovascular bundle spare technique in radical cystectomy. Methods: Between March 2010 and December 2011, a total of 26 bladder cancer patients were treated with radical cystectomy, and intrafascial neurovascular bundle spare technique was applied in all these patients. Mean age of 26 patients was 56.1 y (45 66). Among 26 patients, 21 ...

Generally, a typical problem which is crucial in a manufacturing system is increasing the production rate.  To cope with the problem, different types of techniques are used in companies by trial and error which imposes high costs on them. Using simulation as a tool for assessing the effect of alterations on the performance of the overall system might be significant. This paper considers a simul...

We analyze a solution to a variant of the Towers of Hanoi problem, in which multiple spare pegs are used to move the disks from the source to the destination peg. We also discuss the interesting relation between the number of disks and the total number of disk moves when the number of spare pegs is a function of number of disks.

Spare parts inventories assist maintenance staff to keep equipment in operating condition. Thus the level of spares stocked has a direct bearing on machine availability. This paper presents an innovative risk based approach for spare parts inventory optimisation. Research presented here is in response to a real-life problem of developing a methodology for optimising the stocking of spare parts ...

Flexible real-time applications have predefined temporal limits within which they can operate. Real-time systems that support flexible scheduling need a mechanism to distribute spare capacity in a predictable way among the running applications with respect to the applications’ temporal limits and available system resources. This paper introduces a greedy algorithm for spare capacity distributio...
