Simulation-optimization of automated material handling systems in a healthcare facility

A Simulation-based Design Framework for Automated Material Handling Systems in 300mm Fabrication Facilities

This paper describes a methodology to tackle the problem of designing Automated Material Handling Systems (AMHS) for 300mm wafer fabrication facilities. The proposed framework divides the design process into two levels: architectural and elaborative. Prior to the design, fab data are preprocessed using simulation of manufacturing operations. The output data and fab requirements data are then pr...

Track layout accommodating dynamic routing in automated material handling systems

Buffer Management for Automated Material Handling Systems in Semiconductor Industries

The automated material handling system (AMHS) is a highly automated transport solution of actual 300mm semiconductor waferfabs. The big logistic challenge in such a running system is the just-in-time delivery of lots (carriers). Therefore, beside tracks and vehicles, there are different storages (stocker) and buffers (under track storages and load ports) integrated in such a transport system. T...

Integrated technique for the optimization of healthcare facility problem

Access to basic health care services is one of the major issues in developing nations. The location of health care facilities is an important aspect in health care delivery. It is therefore necessary for health care services to be located optimally to serve the demands well. This study develops an integrated methodology in the field of healthcare location which minimizes the weighted average Eu...
