Age replacement models: A summary with new perspectives and methods
( Elsevier Ltd , 2017 , Article Review)Age replacement models are fundamental to maintenance theory. This paper summarizes our new perspectives and hods in age replacement models: First, we optimize the expected cost rate for a required availability level and ... -
An integrated linguistic MCDM approach for robot evaluation and selection with incomplete weight information
( Taylor and Francis Ltd. , 2016 , Article)Nowadays selecting the most suitable robot is a difficult task for manufacturing firms due to increase in production demands and availability of various robot models. Robot evaluation and selection can be regarded as a ... -
Comparisons of replacement policies with periodic times and repair numbers
( Elsevier Ltd , 2017 , Article)Periodic replacement policies modeled with the history of minimal repairs have been studied extensively. However, in the viewpoint of cost rate, there is no literature to compare replacement polices which are carried out ... -
Comparisons of standby and parallel systems in reliability, replacement, scheduling and application
( SAGE Publications Ltd , 2016 , Article)This paper compares the standby and parallel systems through the following analyses: reliability measures such as reliabilities, mean times to failure, and failure rates are first compared. These comparisons are reconsidered ... -
Constant and Random Full Backup Models with Incremental and Differential Backup Schemes
( World Scientific Publishing Co. Pte Ltd , 2017 , Article)It has been commonly known in a Database Management System that constant plans of incremental/differential backup schemes are set up and their full backups should be done to balance the costs of data backup and failure ... -
First and Last Triggering Event Approaches for Replacement with Minimal Repairs
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)To make effective use of a running system, this paper proposes that, when replacement times could be scheduled at a planned time T of operation, and at a number N of minimal repairs, the newly proposed approach of whichever ... -
Over-time and over-level replacement policies with random working cycles
( Springer New York LLC , 2016 , Article)When a unit is running successive works with cycle times, it would be uneconomical or impractical to do maintenances during any working cycle. This paper firstly reviews two replacement models proposed in literatures as ... -
Preventive replacement policies with aging failure and third-part damage
( SciTePress , 2016 , Conference Paper)In general, corrosions, degrading the mechanical strength of pipelines gradually with its age in a stochastic way, is the predominant cause of pipeline leaks. In addition, the third-part damage is the leading cause of ... -
Random number of units for K-out-of-n systems
( Elsevier Inc. , 2017 , Article)This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ... -
Random number of units for K-out-of-n systems
( Elsevier , 2017 , Article)This paper takes up the reliability and preventive replacement problems for a K-out-of-n system, where K is a stochastic parameter provided. Firstly, we consider the case when K is predefined as constant numbers as is done ... -
Replacement policies for a parallel system with shortage and excess costs
( Elsevier Ltd , 2016 , Article)It has been assumed in most maintenance models that (i) the number of units for a parallel system can be predefined precisely, (ii) maintenance cost after failure should be avoided, and (iii) age replacement can always be ... -
Replacement policies for age and working numbers with random life cycle
( Taylor and Francis Inc. , 2017 , Article)It has been modeled for several replacement policies in literatures that the whole life cycle or operating interval of an operating unit should be finite rather than infinite as is done with the traditional method. However, ... -
Replacement Policies for Periodic Damage Models
( World Scientific Publishing Co. Pte Ltd , 2017 , Article)A new periodic damage model is proposed in this paper, where the damage produced by shocks is only measured at periodic times, without considering the stochastic shocks and the cumulative process of damage in discrete ... -
Replacement policies for periodic damage models
( International Society of Science and Applied Technologies , 2016 , Conference Paper)A new periodic damage model for preventive replacement policies is proposed in this paper, where the damage produced by shocks is only measured at periodic times, without considering the mathematical models of the stochastic ... -
What is Middle Maintenance Policy?
( John Wiley and Sons Ltd , 2016 , Article)The main purpose of this paper is to propose several new maintenance policies that can be performed at suitable middle times for trivariate preventive maintenance scenarios. Firstly, characteristics and limitations for the ... -
Which replacement is better before or after a specified time for minimal repair models
( International Society of Science and Applied Technologies , 2016 , Conference Paper)This paper compares the models of replacement first, replacement interval, replacement last and replacement overtime to decide which policy would be better before or after a specified time T in the viewpoint of cost saving. ...
