摘要
资源有限性引起的项目间资源冲突是影响工程项目群建设周期和效益的重要因素。构建一个能够准确描述工程项目群实施全过程中任务关系、资源需求以及任务持续时间等资源管理相关信息的资源模型是进行工程项目群实施阶段过程管理和资源优化配置的关键。针对非消耗性资源的属性及工程项目群实施阶段资源管理的建模需求,基于HTCPN定义了工程项目群实施阶段资源模型。该模型能够准确描述工程项目群实施全过程,可以进行资源冲突发现、运行时间、资源计划方案优选的仿真分析。借助CPN Tools仿真平台,以某工程项目群实施阶段为例进行资源模型的构建和仿真,验证了基于HTCPN构建工程项目群实施阶段资源模型的正确性和有效性。
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 man- agement, 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 construc- tion 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 correct- ness and effectiveness of the model.
