With the rapid development of the domestic construction industry, the traditional engineering management model can not meet the needs of a large number of construction project information exchanges. Only realizing informationization of construction engineering management, can reduce the cost of construction projects, improve the efficiency of project management and construction progress. This paper analyzes the current situation of construction management informatization, and puts forward some suggestions to strengthen the construction management information construction.展开更多

In this paper, we investigate a key issue emphasized on a route of multi-level information evolution on the side of large-scale feedback, where material-flow states could evolve from the measuring data(local states) to networked event-type information cells(global states) and consequently to the key performance indicators(KPI) type information(gross states). Importantly, with adapta-bilities to frequent structural dynamics residing in running material flows, this evolving route should be modeled as a suit of sophisticated mechanism for large-scale dynamic states tracking and representing so as to upgrade accu-racy and usability of the feedback information in MES. To clarify inherent complexities of this evolving route, the investigated issue is demonstrated from extended process systems engineering(PSE) point of view, and the TRF principles of the multi-level feedback information(states) are highlighted under the multi-scale methodology. As the main contribution, a novel mechanism called TRF modeling mechanism is introduced.展开更多
