Infrastructures in the Netherlands are rated according to a discrete condition scheme and the results are registered in an extensive database. The paper discusses the application of a continuous-time Markov process for modelling deterioration and introduces new results for optimizing periodic inspections and preventive maintenance. The focus of this discussion is on the condition of superstruct...

Cities composed of many mountainous areas necessitate the use tunnels for roads and highways with a potential safety hazard. To determine tunnels, periodic tunnel inspections mainly rely on manual work, which is dangerous slow. Therefore, this paper proposes an auto-inspection system inspection consisting robotic arm, laser sensors, radar to free inspectors from hazardous environments high-inte...

We have delineated some of the factors affecting the performance of spectrometers and spectrophotometers in the clinical laboratory and have presented some of the methods for verifying that these instruments are functioning properly. At a minimum, every laboratory should perform periodic inspections of spectrometric functions to check wavelength calibration, linearity of detector response, and ...

We examine the interplay between two important decisions that impact environmental performance in a production setting: inspections performed by a regulator and noncompliance disclosure by a production …rm. To preempt the penalty that will be levied once a compliance violation is discovered in an inspection, the …rm dynamically decides whether it should disclose a random occurrence of noncompli...
