Economic optimization of off-line inspection with inspection errors
Journal of the Operational Research Society, 2003Summary: We find the optimal inspection policy for the production process of a finite batch of items with inspection errors. We study the effects of inspection errors on the optimal solution and determine which unit should be inspected to minimize the expected total costs.

Off-line inspections under inspection errors
IIE Transactions, 2009The problem of off-line inspection is of both practical and theoretical interest. It has been the subject of research in somewhat simplistic scenarios. In this paper, the theoretical coverage of this problem is extended to include inspection errors. In particular, a process which is subject to random failures that sequentially produces a batch of units

UAS: IoT on-line sensors for power line inspection
2020 IEEE SENSORS, 2020UAS may carry multiple sensors as payload resulting in a multisensory flying platform able to capture images or other data which can be used for professional analysis in electrical industry. While some of these sensors do not need precise orientation, others, like cameras cannot perform their functionality without it.

POLIBOT – POwer Lines Inspection RoBOT
Industrial Robot: An International Journal, 2018Purpose Several studies have aimed to develop robotic systems which move in transmission lines. Until this moment, all of them have a high weight and cost associated with the equipment and reduced battery autonomy time. In this context, this paper aims to propose the POLIBOT (POwer Lines Inspection roBOT) with low cost and weight, enabling the ...

ANALYSIS OF ACCURACY OF IN-LINE INSPECTION RESULTS
Russian Journal of Construction Science and Technology, 2018The paper presents a method for assessing the accuracy of in-line inspection (ILI) results. The main objective of the method is to determine whether the measurements obtained by ILI are adequate and acceptable. If too few measured dimensions of defect parameters (for example, their depths) fall within the range of values obtained using verification ...

New Robot for Power Line Inspection
2008 IEEE Conference on Robotics, Automation and Mechatronics, 2008Power line inspection is of the utmost importance for the reliability and stability of electric power distribution. However, manual inspection is a hazardous, slow, expensive and unreliable task. Therefore, new highly specialized robots are required to improve the overall quality and safety of the power line inspection.

On‐line evaluation of the stability of an inspection process
Applied Stochastic Models in Business and Industry, 2009AbstractThis article proposes control charts to monitor an inspection process based on the defective proportion of the inspected parts. The focus is on inspection process where the incoming parts form a sequence of independent units, such as unrelated clients arriving at a service facility.

Expliner - Robot for inspection of transmission lines
2008 IEEE International Conference on Robotics and Automation, 2008The inspection of high-voltage transmission lines is a dangerous and time-consuming job, that relies on especially trained workers operating tens of meters above the ground, and close to live lines with thousands of volts. This paper presents the development of a tele-operated robot designed for preventive maintenance of high-voltage lines.
