Security is a vital issue in the usage of Automated Teller Machine (ATM) for cash, cashless and many off the counter banking transactions. Weaknesses in the use of ATM machine could not only lead to loss of customer’s data confidentiality and integrity but also breach in the verification of user’s authentication. Several challenges are associated with the use of ATM smart card such as: card clo...

To optimize belt conveyor system (BCS) performance, a reasonable assessment of system reliability is desired and the decisions of how often to perform maintenance and the optimal occasion to replace a component are required. Intelligent belt conveyor monitoring (BCM) may automate the maintenance process. To realize such an intelligent system most of parameters of BCS have to be monitored. Too m...

Resources allocated to software maintenance constitute a major portion of the total lifecycle cost of a system and can e€ect the ability of an organization to react to dynamic environments. A major component of software maintenance resources is analyst and programmer labor. This paper is an experimental evaluation of how the Human Information Processing (HIP) model can serve as a framework for ...

Nowadays, production systems seek to integrate production and maintenance activities. An effective maintenance plan can improve maintenance stability and system performance. Machines that stop for repairing operation impose a high cost on the system. On the other hand, there are always some intangible situations during a production process in which repairing activities can be carried out. If th...

 In this paper a single server queuing production system is considered which is subject to gradual deterioration. The system is discussed under two different deteriorating conditions. A planning horizon is considered and server which is a D/M/1 queuing system is gradually deteriorates through time periods. A maintenance policy is taken into account whereby the server is restored to its initial ...

This paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. The failure of each component results in the failure of the system. The components are inspected periodically and their deterioration degrees are monitored. The components can be maintained using different maintenance actions (repair...

This paper presents the steady state behavior and maintenance planning of the bleaching system in a paper plant. The paper plant comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening, stock preparation and paper making, etc. One of the most important functionaries of a paper plant, on which quality of paper depends, is the bleaching system, where rem...
