Due to the complexity of a compiler, it is difficult for compiler developers to prove the correctness of output of intermediate representations or profiling information manually after applying optimizations. Moreover, it is important to choose good test cases to test the optimization code’s changes, however, it is not simple to build separated test cases to cover every possible optimizations. T...

A set of technical, administrative and management activities are done in the life cycle of equipment, to be located in good condition and have proper and expected functioning. This is refers to be, maintenance management system (MMS). The framework and models of assessment in order to enhance effectiveness of a MMS could be proposed in two categories: qualitative and quantitative. In this resea...

Building maintenance management involves decision-making under multiple objectives and uncertainty, in addition to budgetary constraints. This paper presents the development of a multiobjective and stochastic optimization system for maintenance management of roofing systems that integrates stochastic condition assessment and performance prediction models with a multiobjective optimization appro...

The paper deals with a maintenance grouping approach for multi-component systems whose components are connected in series. The considered systems are required to serve a sequence of missions with limited breaks/stoppage durations while maintenance teams (repairmen) are limited and may vary over time. The optimization of the maintenance grouping decision for such multi-component systems leads to...

This paper deals a production and maintenance optimization problem for a wind turbine system in order to satisfy a random demand under given service level. A jointly optimization is made by combining between energy production and maintenance plan in order to establish an economical energy production planning and an optimal maintenance strategy according to the wind turbine degradation. The key ...

A complex repairable system generally adopts multi-grade preventive maintenance. The optimization of maintenance decision making is usually regarded as a complex mathematical problem. This study proposes a three-grade preventive maintenance optimization method for complex repairable system based on field failure data. Specifically, all failures are classified into three categories: minor, moder...
