The journal System evidently needs a new one — at least when it comes to production.
The publication has been forced to retract an article that it published twice — in the same issue.
Here’s what happened:
The publisher regrets sincerely that an error in its production office resulted in the below article appearing in this issue twice. To remedy this error, pages 522–532 from this issue have been retracted.
SYS, 40 (2012) 522–532, http://dx.doi.org/10.1016/j.system.2012.10.017. The duplicate article has therefore been withdrawn.
As a consequence, pages 522–532 related to the duplicate article are missing from the printed issue. The publisher sincerely apologizes for any inconvenience this may cause.
