Factory Level Datasets
Factory Level Datasets
The goal in development of the fab level data sets was to include the minimum information necessary to model a factory. In support of this goal, the data sets were kept as simple as possible, specifically by including data but not modeling assumptions. For example, mean times between failures are provided, but not their distributions. Process holds, engineering holds, and send aheads are also not included. The resulting data is given in six ASCII flat files, containing: product routings and processing times; rework routings; equipment availability; operator availability; product starts; and a comments file.
The testbed currently contains 8 factory-level datasets. Some general information about the datasets follows:

More information is included in the comments file provided with each dataset. The comments files all have the ending .cf (e.g. set1.cf). The comments files each include a revision number for the dataset, and a list of changes made since the last revision was published.
For information on the testbed dataset format refer to the the following pdf document. Each dataset can be downloaded individually using the links provided above or as a group here. There is also a copy of an Excel spreadsheet version of the dataset (.xls) included in most of the sets.
Questions?
For questions regarding the testbed datasets, contact John Fowler (john.fowler@asu.edu). It is requested that anyone who downloads the testbed datasets send an email to John Fowler with your name, address, and purpose for using the testbed. This will allow us to notify you of any changes to the testbed (e.g. when new datasets are released). It will also be helpful, in general, for us to know how many people are using the testbed, and for what sorts of purposes. Also, if you have a data set that you would like to donate, please contact John Fowler. Thank you.
