The value of total cost varies considerablv with the composition differences, so the values of e should be optimized in order to obtain minimum TAC of a MEN. This articleconsiders ε as a set of unequal variables for each equilibrium equation of a rich-lean stream pair, employing them to build the CID and mathematical model, which optimizes the structure and composition differences simultaneously. Two examples are applied to illustrate the proposed method and the results demonstrate that the approach introduced by this article is simpler and more convenient than the methods in previous literatures.展开更多

Albania is an economy characterized by a high percentage of agriculture of gross domestic product （GDP） with 25%. Actually, Albania for many decades and varied reasons will remain, to the future, a country where agriculture and especially livestock will play an important role. This paper starts from the actual situation and tries to find solutions to any effective management＇s problems. Treatments in this paper are based on literature reviews and combined with empirical research. Part of this article clarifies the scope of modem agricultural business and the impacts of circumstances of biological parameters on a sustainable livestock.展开更多
