Recycle economy is a kind of practice mode that the international community promotes continuable development,it emphasizes that utilizes resources and protects the environment most effectively,is shown as " resources ——Products ——Regenerated resources " style of economic increase,accomplishes production and consumption," disposal of pollutants minimize,make rubbish into resource and make it innoxious",obtains the most satisfactory economic benefits and environmental benefits with the minimum cost.
It emphasize that we should utilize resources and protect the environment most effectively, which is shown as " Resources --Products -Regenerated resources " style of development of economy and make sure " minimizing disposal of pollutants, reclamation and innocuity of waste product" of production and consumption, obtain the greatest economic benefits and environmental benefit with the minimum cost.
The key content of the thesis is the site selection standing on the standpoint of enterprises considering the distribution center, the principle that enterprises pursue is a economic benefits question, so we sum up the site selection of the distribution center of the logistics as the question of the minimum cost, namely that asked and solved and made transporting the cost, variable cost and fixed cost is the minimum optimization question.
On the basis of analysis on the north-east economy, energy, resources and the power industry, use the investment decision and the optimization theory, the purpose of this paper is to focus on research optimization programme of the project of the power in the coal base, try hard to propose the minimum cost power expansion plan.
The minimum cost multicast routing algorithm based main frame tree is presented The steps of the algorithm are,to find the K nodes with minimum cost in the network firstly,and make a trunk using these nodes;
Dijkstra's algorithm is modified to choose the minimum cost path from the directed graph,of which the node cost corresponds to the single-word frequency and the edge cost to the double-words frequency.
A new heuristic algorithm based on the minimum cost route concept is developed for the design of large self-healing ATM networks using path restoration. The results illustrate that the heuristics is efficient.
In order to meet the consumer demands just right, enterprises should do two things: first, to look for the best combination of the quality and cost through Value Analysis so as to realize essential needs with the minimum cost;
The target of aviation project's risk management is controlling and coping with risk (emerging in the running of the project), preventing and decreasing losses, mitigating or eliminating detrimental effects of risk, and acquiring satisfactory consequences to the project's securing guarantee at the minimum cost, so as to ensure the project to carry cut successfully.
In this paper, a single point turning is given as an example to demonstrate the fundamental principle of MAC. The mathematical models of the maximum profit rate or production rate and the minimum cost as the objective of optimization and the calculation program of MAC are also illustrated.
