Probabilistic Lifetime-Oriented Multiobjective Optimization of Bridge Maintenance: Single Maintenance Type

Optimization of single outsourcer–single subcontractor outsourcing relationship under reliability and maintenance constraints

In this paper, we focus on outsourcing activities optimization problem in single period setting. In some situations, capacity planning or outsourcing is a one-time event and can be modeled as a single period problem. The aim of this research is to balance the trade-off between two echelons of a supply chain consisting of a single outsourcer and a single subcontractor. Each part is composed of a...

Optimization of Bridge Maintenance Management Using Markovian Models

This paper presents a systematic approach for bridge maintenance management that combines a stochastic Markovian performance prediction model with a multi-objective optimization procedure to determine the optimal allocation of funds and prioritization of bridges for maintenance, repair and replacement (MR&R). The prioritization of the bridges is based on the satisfaction of several conflicting ...

The Use of Stochastic Processes in Bridge Maintenance Optimization

We introduce an approach for modelling the structural deterioration of components of bridges for maintenance optimization purposes. The Markov chain model is found in the maintenance and repair problems since the early 60's, is introduced to the maintenance of road infrastructure in the 1980's, and is made to drive the current bridge maintenance optimization systems. While this model results in...

Model of Lifetime-extending Maintenance

In this paper, a new maintenance model is presented in which both the interval of lifetime extension and the interval of preventive replacement can be optimised. Through lifetime extension, the deterioration can be delayed as such that failure is postponed and the lifetime of a component is extended. Through replacement, the condition of a component can be restored to its original condition. Th...
