However, this technique does not fit for low-cost inspection as it needs various sensors both inside and outside the pipelines.
There was no difference in total costs, treatment costs, total drug costs, inspection fees, bed fees, nursing fees, or hospital stay between older diabetics and older nondiabetics (P>0.05).
There was also no difference in total costs, treatment costs, total drug costs, inspection fees, bed fees, nursing fees, or hospital stay between younger diabetics and younger nondiabetics (P>0.05).
In addition, older patients with diabetes incurred lower total costs, treatment costs, total drug costs, inspection fees, consultation fees, and bed fees than younger patients without diabetes (P<0.05), and mean hospital stay was shorter for older diabetics than for younger diabetics (P<0.05, Table 3).
The cost of inspection is approximately one-third of acquiring and operating composite structures.
The effect of false alarms and miss detections on the global cost of inspection planning is underlined through a basic example.
The objective of preventive maintenance is the minimization of the total cost of inspection, repair, and downtime (also known as lost production capacity or reduced product quality).
As a consequence, a smart port-of-entry selection policy must trade cost of inspection with security, in order to fit into the dynamic operation of a port.
Total cost of inspection per unit time equals Equation 10: TC I = ∑ i = 1 n I i Q i T i = ∑ i = 1 n I i D i 1 − p 2 i ; i = 1, …, n.
Thus, the non-destructive testing techniques applied for such materials should be evaluated in several categories: effectiveness in detection, localization and identification of damage in possible early phase of their development, complexity of application and a cost of inspection.
In this study, total costs are expressed as the summation of the costs of inspection, repair and failure: (9) C T (x ) = C I (x ) + C R (x ) + C F (x ), where C I, C R and C F denote the cost functions associated with inspection, repair and failure respectively.
