Cost-effectiveness:
Cost-benefit analysis: A method to assess the value of the project by comparing all costs and economic analysis of the project, the cost-effectiveness as an economic decision making, aim to seek to minimize the cost to obtain the maximum benefit in the investment decision-making. In this method, a lot of projects and all costs and benefits of decisions will be to list, and then quantified.
Cost-benefit analysis, cost effectiveness analysis is also known as:
This is the planning, budgeting and procurement systems engineering is a method or device. From the United States, 60 after time, this method widely used in the industrial sector. In order to achieve the purpose of an economic or military, can choose a lot of economic and technical programs, the programs aim to achieve in effect vary on consumption and costs. Through a cost-benefit analysis to identify the most optimal solution. The whole project will do research system designed to meet the overall analysis equivalent to achieve. This thing has a lot of uncertainty, so many parameters need to assume an experiment to test the system works by means of cost-effectiveness analysis and comparison of trade-offs.
Integrated use, comprehensive knowledge and methods related equipment design and mathematical programming models design, operations research, economics and engineering.
Network configuration, this also needs to be considered. Proposed network topology cost effectiveness C =. 1 / (N * C Node + L * C Link ) * D, where N , L denotes the number of vertices and edges networks, C Node , C Link represents network nodes and edges overhead, D represents the diameter of the network.
for example:
In many variations of network hypercube network , such as Gaussian hypercube (Gaussian hypercube) and switching hypercube are removed network portion connecting side to balance network functions and hardware overhead by, for maximum cost-effectiveness C .
