"cost sum" is not a correct or usable phrase in written English.
You can use "cost" or "sum" in a sentence, but not together. For example, "The cost of the project came to a considerable sum of money."
As a measure of cost-effectiveness, the procedure estimates minimum life-cycle cost, sum of initial construction cost and excepted damage cist over life-cycle of the structure.
Fast and elitist non-dominated sorting genetic-algorithm (NSGA-II) was applied to obtain the maximum effectiveness and the minimum total annual cost (sum of investment and operation costs) as two objective functions.
Both the Genetic Algorithm and the Particle Swarm Optimization Algorithm are applied to obtain the minimum total annual cost (sum of investment and operational costs) as objective function with discrete and continues variables.
Then, the fast and elitist NSGA-II (Non-dominated Sorting Genetic Algorithm) is applied to maximize the thermal efficiency and minimize the total annual cost (sum of investment cost, fuel cost and environmental cost) simultaneously.
The expectation cost (sum of the damage risk potential plus cost of restoring the levee) is adopted for the comprehensive evaluation of river levees where the application is limited to damage done to the levee itself and excludes damage to human life and property.
In third step, distances between nodes are determined and multiplied by the corresponding transportation cost; sum of the results gives total cost for each link.
The resulting difference between price and marginal cost, summed over the number of copies sold, will generate revenues to offset the cost of expression.
The optimal product-requirement communication spanning tree is the spanning tree with minimum total routing cost summed over all pairs of vertices.
Robustness to model parameter uncertainties is accomplished by optimizing the cost summed over models, by adjusting the learning rate as a function of frequency, and by relaxing the zero error requirement as a function of frequency.
Then the real cost sums of 2002 and 2008 were standardized to the 2005 reimbursement level.
And total cost sums over error cost, weight cost, and configuration cost.
