In September 2006, the viaduct de la Concorde in Montreal collapsed. The consequences were two crushed cars, five dead and six injured. The inquiry Commission declared that this tragedy cannot be attributed to one cause only, and that multiple faults resulting from sequential causes have accumulated and resulted in these consequences. In August 2007, part of the underground structure of downtown Montreal was evacuated after spotting some indication of damage done by through-flow water. In 2010, the oil spill of British Petroleum in the Gulf of Mexico took place. The accident involved a loss of control over the pressure in the well followed by the failure of the well's blowout preventer. Eleven people died as a result of the accident and others were injured. New and old challenges continue to plague the researchers in the field of Physical Asset Health Management (PAHM), and in particular in the field of Condition Based Maintenance. The degradation and failure problems as well as some of the phenomena that physical assets are experiencing are complex. By complex, we mean dynamic and chaotic behavior due to non-homogeneities in tasks and usage conditions, noisy and non-linear, multiple interacting causes. Therefore, forecasting can be practically impossible when based on the traditional model-based predictive algorithms. Traditional as well as new techniques should be adapted to the present needs of better follow-up and maintenance of these physical assets. Logical Analysis of data (LAD) is a data mining, artificial intelligence, machine learning approach that is based on pattern recognition. Initially it started in 1988 at Rutgers University Center for Operations Research (RUTCOR), and it was applied mainly in the medical field. In 2007, it was applied for the first time at École Polytechnique by Dr. Yacout's research group in the field of PAHM. After thirteen publications, this approach seems to offer new ways for solving the above-mentioned problems. This proposal aims to continue the in-depth study, adaptation, and development of techniques based on this approach, for the field of PAHM, and the development of an integrated tele-maintenance intelligent system based on LAD.

2006年9月，后果是两辆破碎的汽车，五人受伤。 SOTTER SOME造成了整个流水的损害，墨西哥湾的英国石油漏油使事故失去了对井的控制权。其他人受伤。是复杂的。更好的thysical ASET（LAD）是一种基于模式识别的数据挖掘，这是在Rutgers University的运营研究中心（RUTCOR）的。在2007年的医疗领域，在13个出版物之后，这种方法似乎是解决上述问题的新方法。 PAHM的领域以及基于LAD的综合tele-Meaintence智能系统的开发。
