Abstract:

Resource conflict between the project caused by the limited resources is an important factor affecting the construction period
and benefits of the construction programme． The building of an accurate model which can describe the information about resource management，
such as relations among tasks，resource requirements and task duration and so on is the key to the process management and
optimal allocation of resources for implementation stage of construction programme． Resource model for implementation stage of construction
programme was defined based on HTCPN by analyzing the resource characteristics of non － depletable resources and the modeling
requirements for implementation stage of construction programme． The model can accurately describe the whole process of programme，
and also can find resource conflict，analyze the construction period and choose the optimal resource planning by simulation． With CPN
Tools simulation platform，taking an example of a construction programme，the authors built its resource model and verified the correctness
and effectiveness of the model．
