目前,关键链法研究多集中于缓冲区设置,对工序排布研究不多,在工序和项目排布功能上较为薄弱.针对这种情况,提出一种结合设计结构矩阵(DSM)和关键链法(CCM)优点的DSM-CCM法探索解决相关问题.该方法利用设计结构矩阵处理项目间排序,处理耦合效应,降低工序迭代频率,基于关键链法思想对项目群工期进行科学合理安排,提出DSM-CCM法项目群进度管理运用全流程模型,并通过实例进行说明,可以较好地满足项目群进度管理需要.

A quantitative and qualitative study on research developments in automation field is conducted based on the papers published in Acta Automatica Sinica during 2011 to 2016 from the aspects of productivity, citations, topics, usage, and coauthorship networks. The most productive authors, institutions, and the most cited papers, most popular papers, as well as the most frequent topics and their trends are identified and analyzed. Social network methods are employed for revealing collaboration patterns among contributors through author-level coauthorship. It is indicated that the automation field has made tremendous progress and Acta Automatica Sinica has contributed significantly to accelerate the growth over that period. The findings can help scientists in automation field to understand research developments, enhance academic exchanges,and promote collaborations as well.

Existing research on the information value of a single microblog are generally based on multi-dimensional factors that form the single microblogging information value,analyzing the weight of each factor and then evaluating the overall value,which results in the computational complexity problem. However,due to the Chinese semantic complexity,this transcendental method of analysis will inevita-bly be in question of"over generalization". Since the nature of the forwarding behavior is the recognition of the microblogging informa-tion value,and the ratio between the forwarding number and the total number of people receiving the information reflects the widespread impact of the information,the research based on these two factors are worth considering. In this paper,introduce a novel concept of"sin-gle microblogging influence saturation" in perspective of the follower behavior and the influence coverage ratio,study the value of single microblgging information value,which effectively expands the research ideas.

This paper proposes a lineage tracing frame for Extraction-Transform-Load(ETL) process,and discusses some key issues in this system,such as classifying the transformations,the designing of metadata,constructing transformation series,tracing process design and the tracing methods for every type of the transformation.The metadata for tracing is injected into the package file,these information are extracted when tracing query were proposed to support data tracing.

Data provenance is a hot research issue these years. This paper introduced its concept and profile of this field first based on related works. Then divided it into two parts,one was the model in open world which including two typical formal model,the other was the model in closed world,which including database provenance models and workflow provenance models. After this,it compared over ten provenance systems in technical side. At last proposed some promising aspects of this field.

Software reliability testing is the important process of high-trust software's quality assurance. And software usage model is the foundation of software reliability testing. With more and more application to software development, UML has become industrial standard de facto. It is very meaningful to research software reliability testing based on UML. Software usage model can be derived from UML artifacts, such as usecase diagrams, sequence diagrams and activity diagrams, which have been generated during software development early stages. Then testcase can be gotten easily from it.
