Integrated Maintenance Scheduling for Semiconductor Manufacturing
نویسنده
چکیده
We present a maintenance scheduling problem arising from semi-conductor manufacturing which is characterized by low resource contention and multiple complex objectives and preferences. Since semi-conductor manufacturing involves a very high degree of uncertainty at the level of detailed operations, such as machine availability, yield, and processing times, generating a maintenance schedule which takes into account production operations is a challenging problem. We have developed an integrated approach, with respect to production operations, which uses simulation to estimate expected levels of work in process in the fab. We present details of our solution approach which is based on goal programming, constraint programming and mixed-integer program-

Bi-level Model for Reliability based Maintenance and Job Scheduling
Many defects in manufacturing system are caused by human resources that show the significance of the human resources in manufacturing systems. Most manufacturers attempt to investigate the human resources in order to improve the work conditions and reduce the human error by providing a proper work-rest schedule. On the other hand, manufacturer deal with machine scheduling based on demand and wo...

We address a novel integrated maintenance and production scheduling problem in a multi-machine and multi-period production system, considering maintenance as a long-term decision. Deterioration of machines over time decreases production capacity. Since maintenance activities improve machine conditions, increasing production capacity, but also take time that cannot be used for production, the ch...
