Performance Analysis of a Manufacturing SystemWith Job Failures Using Jackson Networks

摘要

Optoelectronic manufacturing comprises of assembly and subsequent testing in a flow shop like setting withrnmultiple servers at each stage. The assemblies could fail at any stage, and may be routed back to the same stage or tornany one of the preceding stages for troubleshooting and rework. The failed assemblies circulate in the system untilrnthey pass all the tests and hence pose challenges in estimating the performance measures. The manufacturing systemrnunder study is modeled using Jackson networks and the performance measures were estimated and compared to arnsimulation model. A mathematical model to optimize the number of servers at each stage is also presented.
