As the optimization progresses and the optimal maintenance schedule is found, the costs associated with repair increase, but this allows a subsequent decay of the costs associated with failure, leading to a decrease of the total costs associated to the structure.
The effort was tremendously successful in reducing sulfur dioxide emissions that were poisoning lakes and streams, contaminating soils and accelerating the decay of buildings, at a cost lower than even its advocates anticipated.
This circumstance causes to decrease of the incentive and decrease of the decay rate of the cost of solar and wind energies.
After being abandoned for the last 40 years, he said, the station's exterior could be in such a state of decay that the costs of restoring it would prevent any developer from wanting to do anything with the site at all.
The generalized network model, for which we derive formulae for the arc and path multipliers that capture the underlying physics of radioisotope decay, includes total operational cost minimization, and the minimization of cost associated with nuclear waste discarding, coupled with capacity investment costs.
Each stage of decay involves different and distinct treatment implications in terms of cost, staff time, and management.
k is a constant discounting the cost of premature termination, to take into account mechanisms of cost reduction such as nonsense-mediated mRNA decay or a selectively maintained deficit of near-stops in coding sequences.
By allowing shortages and backlogging, the impact on the cost from the decay of the products can be balanced out.
Thus, the investigation of drying kinetics of capillary absorbed water can be very useful in understanding the causes of decay of building materials and in saving cost and improving the energy efficiency of constructions.
Decay of building stone causes considerable damage and costs worldwide [1] and the problem will be amplified in some regions of Europe by ongoing climate change [2, 3].
