But at present, the fields of enterprise and theory have not attached importance to the problem of enterprise product mix adjustment, which is mainly reflected in the following aspects. The first is that most enterprises maintain existing situation of product and enterprise and solve sale problem by the way of sales promotion while facing market problem. The second is that most enterprises follow others blindly while consider the problem of market entry, but is passive not active while facing market dropout. The third is that in the aspect of management most enterprises don"t make adaptive managerial strategy according to enterprise"s interior and exterior situation, but flow the routine "learn from successful enterprise, elude failing enterprise". The fourth is that the study on the enterprise product mix adjustment from the side of theory is scarce and fragmentary, immethodical.

但是，目前企业产品结构调整的问题还未引起企业界和理论界的重视，主要体现在：一是面对市场问题，大多数企业是维持现有的产品和企业状况，通过促销手段来解决产品销路问题；二是对待企业产品市场进入的问题上，大多数企业是盲目跟进；而对产品的市场退出，大多数企业往往是被动而非积极主动的；三是在经营方面，大多数企业基本上走的还是"学习成功企业，规避失败企业"的路子，没有从企业自身的内部条件出发，为企业量身制定适合的经营战略；四是迄今为止理论界对企业产品结构调整问题的研究还是少之又少，有关产品结构方面的研究还只是零星、不成体系的。

For the single objective optimization, the decomposition and coordination method is adopted to build the decomposition and coordination model according to the existing sub-area division conditions of power networks. Then using the Augmented Lagrange method, the minimization problem of decomposition and coordination model can be changed to the saddle point problem of augmented Lagrangian function.
