Sexual selection and the maintenance of sex

Nature, 2001
Sex is expensive. A population of females that reproduce asexually should prima facie have twice the growth rate of an otherwise equivalent anisogamous sexual population lacking paternal care, or a population with modes of paternal care that can be co-opted by parthenogenetic females.

Optimal predictive selective maintenance for fleets of mission-oriented systems

International Journal of Production Research
In many settings, fleets of assets must perform series of missions with in-between finite breaks. For such fleets, a widely used maintenance strategy is the fleet selective maintenance (FSM). Under resource constraints, the FSM problem selects an optimal

Risk Assessment Tool for Maintenance Selection

2006 International Conference on Dependability of Computer Systems, 2006
Selecting maintenance policy is important for efficient operation of contemporary complex computer systems, when not only reliability, but also financial factors must be taken into consideration. This work presents an approach which is based on the concept of a life curve and discounted cost used to study the effect of equipment aging under different ...

Condition-Based Selective Maintenance Optimization for Large-Scale Systems Consisting of Many Homogeneous Units

IEEE Transactions on Reliability
This study considers a maintenance optimization problem for a large-scale system comprising many homogeneous units. Each unit degrades by transitioning on predefined health states, where transition times follow general distributions from one state to ...

Selective maintenance of multi-state series systems considering maintenance quality uncertainty and failure effects

Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering, 2021
In order to improve the lifetime and reliability of equipment operation stage, it is necessary to carry out maintenance for components. The typical selective maintenance model does not consider the maintenance quality uncertainty and the failure effects,

Knowledge Transfer-Based Multifactorial Evolutionary Algorithm for Selective Maintenance Optimization of Multistate Complex Systems

IEEE Transactions on Reliability
This article focuses on multitask selective maintenance (SM) for multistate complex systems, with the goal of selecting subsets of feasible maintenance actions on multitask systems simultaneously due to limited resources.

On sequence planning for selective maintenance of multi-state systems under stochastic maintenance durations

European Journal of Operational Research, 2018
In many industrial and military environments, systems are required to execute a sequence of missions with a finite break between two adjacent missions. Due to the limited maintenance resources, such as budget, time, and manpower, etc., it is oftentimes ...

Maintenance strategy selection and its impact in maintenance function

International Journal of Operations & Production Management, 2015
Purpose– This paper aims to synthesize and categorize the published literatures related to maintenance strategies formulation, selection and implementation in various industries. The purpose of this paper is to develop a conceptual framework based on literature review for formulation of maintenance strategies, selection and the implementation of ...

Establishing Maintenance Resource Levels Using Selective Maintenance

The Engineering Economist, 2006
We address the performance of a repairable system that is required to perform a sequence of equally spaced, identical missions with breaks between missions. The system is series-parallel in structure, and component repair can only be performed during breaks between missions.
