CBFEC emphasizes direct correspondence of concepts in EC with its software architecture for ease of understanding and using; minimal coupling with specific problem structure for easy adaptation it to solve a large number of wholly different problems; interface-centered design for extendibility. To achieve those objects, the problem-solving method of EC is analyzed and the problem-solving procedure of EC is divided into three interactive aspects: population-based stochastic searching mechanism, problem specific information to implicitly guide the stochastic searching, and the observation and control of the computation procedure of EC. Then the key concepts of EC are identified in those three aspects; the normal implementations of those concepts are summarized; the interfaces represents those concepts in software are abstracted; the collaborations of components through those interfaces are designed. CBFEC is implemented on mainstream component software platform COM/DCOM (Component Object Model/Distributed COM from Microsoft), which includes interfaces definitions, commonly using EC components implemented those interfaces, such as Simply EA component, Steady State EA component, EA component, EA component, Population component, Tournament Selection component, Linear Ranking Selection component, Nonlinear Ranking Selection component, Random Number Generator component, etc, and the collaborations of those components through those interfaces.

具体的做法是把演化计算看作是基于组件的软件工程的一个应用领域：首先分析了演化计算求解问题的一般思路和方法，把演化计算问题求解过程分为："设计基于群体的随机搜索机制"、"研究问题的性质并以此隐含地定义算法的搜索方向"和"求解过程的观察与控制"三个部分；然后分别找出各个部分中的关键概念，总结这些概念现有的一般实现方法，抽取其本质，以此结合设计模式来定义组件软件的接口；通过分析演化计算各个概念之间的相互联系来设计组件软件间通过接口的进行交互的方式；最后还在目前一种主流组件软件开发平台COM／DCOM（微软提出的组件对象模型）的基础上实现了常用的演化计算组件，如简单演化算法组件、稳态演化算法组件、演化算法组件、演化算法组件、种群组件、锦标赛选择策略组件、线性排名选择策略组件、非线性排名选择策略组件、随机数发生器组件等等。

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。
