Welcome to Volume 20, Number 3 of the FabTime Cycle Time Management Newsletter. In this issue we have an announcement about availability of new papers from the Winter Simulation Conference. Our software tip of the month is about saving data table configurations. We have no subscriber discussion this month, but we are seeking feedback about a metric defined in our main article: WIP hours. WIP hours is a metric used to compute the hours of WIP waiting at each tool, normalized by the number of tools that are qualified to run each wafer. We believe the WIP hours could be useful in identifying short-term bottlenecks and tool groups that could particularly benefit from additional cross-qualification. As always, we welcome your feedback.
Welcome to Volume 20, Number 2 of the FabTime Cycle Time Management Newsletter. In this issue we have a call for papers for an upcoming conference. Our software tip of the month is about using our new interface for renaming, copying, and linking to home page tabs. We also have an extensive subscriber submission about capacity planning, on-time delivery, and dispatching.
In our main article, we discuss the metric Green-to-Green (G2G) time, which we are in the process of implementing in our software. This metric captures each instance of downtime, scheduled and unscheduled, from when a tool first goes down until it comes back up, even if there are multiple switches between downtime sub-states in between. We believe that this metric will be helpful to fabs in understanding and reducing downtime-related variability.
Welcome to Volume 20, Number 1 of the FabTime Cycle Time Management Newsletter. It’s hard to believe that this is the 20th year of publication for this newsletter. Many thanks to all who have joined us along the way. We welcome your feedback on topics that we should cover in the coming year.
