BP神经网络在军队采购招标投标管理系统中的应用

招标投标模式是在军队采购活动中应用比较广泛的一种方式。其优势在于：有比较好的公开性。公平竞争，可操作性强，便于实施和管理。但是在招标投标的过程中也存在着一些问题，特别是评标行为的经验不易被吸收推广，评标结果的验证比较困难。在军队采购招投标管理活动中引入BP神经网络评价模型。建立科学、有效的评标系统，来提高军队采购招投标活动的管理水平，提高评标活动的科学性。     

Software Testing Method Based on Model Comparison

A model comparison based software testing method (MCST) is proposed. In this method, the requirements and programs of software under test are transformed into the ones in the same form, and described by the same model describe language (MDL).Then, the requirements are transformed into a specification model and the programs into an implementation model. Thus, the elements and structures of the two models are compared, and the differences between them are obtained. Based on the diffrences, a test suite is generated. Different MDLs can be chosen for the software under test. The usages of two classical MDLs in MCST, the equivalence classes model and the extended finite state machine (EFSM) model, are described with example applications. The results show that the test suites generated by MCST are more efficient and smaller than some other testing methods, such as the path-coverage testing method, the object state diagram testing method, etc.     

Approach of Separately Applying Unit Testing to AspectJ Program

A unit testing approach for AspectJ programs is proposed to separately test aspect units which have their own states. In the approach, aspects under test are converted to classes before execution of unit testing. In the conversion process, the context information passed through pointcut is transformed into advices, then the advices are converted to class member methods, and conflicts in the conversion result, if any, are resolved finally. The unit testing process consists of generating test cases, executing test cases and checking results.
