Throughput analysis is important for the design, operation and management of production systems. A substantial amount of research has been devoted to developing analytical methods to estimate the throughput of production systems with unreliable machines and finite buffers. In this paper we summarise the recent studies in this area. In addition to the(More)
Throughput analysis is important for the design, operation and management of manufacturing systems. Due to the large state space, exact analytical results only exist for two-machine serial lines. To analyse longer lines or more complex systems, the two-machine line model becomes the building block for further development. Therefore, many two-machine line(More)
Manufacturing system design has an impact on product quality. In this paper, we investigate this impact through an application study at an automotive paint shop. Specifically, for repair and rework systems in paint operations, we develop a model to quantify paint quality [in terms of quality buy rate (QBR)] as a function of repair capacity. We show that the(More)
In this paper, we investigate the impact of manufacturing system design parameters on product quality. Specifically, for a manufacturing system with repair and rework, we derive analytical formulas of product quality as a function of repair capacity. We show that product quality can be improved by designing the repair and rework subsystem more effectively.(More)
In this paper, analytical models to study the performance of Andon type transfer production lines are presented. In addition to provide the calculation formulas to evaluate the good job production rates, we show that when repair time is short, introducing Andon to stop the line and solve the problems (or defects) is a better way to achieve high throughput(More)
In this paper, we study a manufacturing system with repair and rework. We show that in such systems the product quality, in terms of quality buy rate (the good job ratio of all jobs), can be described by a function of repair capacity and first time quality (the good job ratio of all first time processed jobs). Variations in first time quality can lead to(More)
