Some Efficiency Measures in the Operation of Flexible Manufacturing Systems: A Stochastic Approach
نویسنده
چکیده
In this document some efficiency measures of the operation of a serial line manufacturing are discussed from a stochastic approach. In this work we use the concept of operations decoupling in manufacturing systems to place buffers between each operation in order to reduce sequential interdependence between downstream and upstream operations. This will also maintain the output of the production line. Some formulas are developed to compute steady-state performance measures and expected production, including the reliability of the system.

The static and analytic scheduling approach is very difficult to follow and is not always applicable in real-time. Most of the scheduling algorithms are designed to be established in offline environment. However, we are challenged with three characteristics in real cases: First, problem data of jobs are not known in advance. Second, most of the shop’s parameters tend to be stochastic. Third, th...
