| Summary: | 碩士 === 國立交通大學 === 土木工程系 === 89 === Interface is a common uncertainty factor in construction region. An idea of that interface management is related completing construction is generally accepted and respected by constructors. But existing technology of schedule and tools, for example, bar char, CPM, PERT, Monte-Carlo simulation, all base on take account of time of single activity. And by the way constructor calculate the finish time of project. So thinking of uncertain factor is also set measure to single activity. However the same uncertainty in different activities may have correlation that is always neglected.
A constructor who has copious experience should envelop a mass of uncertainty factors when he evaluates time of one activity. But he must not differentiate between all uncertain factors; even more consider the time change reduces by the same uncertainty in before and after activities. However the networks model of NETCOR already provides a good base of research to understand each influence of uncertain factor in the activity. Further it also mentions the correlation of uncertainty. This dissertation is base on the networks model of NETCOR and consults the arrangement of interface by the CIAR system to establish a model for evaluating networks under interface effect. The model can express each interface effect in all activities and the relevance of both activities’ interface effect. For this reason, we can further understand the interface effect to time in schedule networks and catch the information for interface management. In the end of dissertation ,we use three examples（two activity, three activity and a small network） to explain how to use and what we can get from the model.
