中文摘要 | 離散事件模擬系統中,模擬資源分派方式通常分為兩種,第一為建構單一模型,並進行各種資源數量組合之分析,以求得最適當的資源組合,第二為考慮各種資源供應方式建構各類模擬模型,再比較各類模型中資源數量組合方式對專案之影響。第一種方式只能針對單一資源供應系統中的資源數量組合進行評估,而無法考量不同資源供應方式對專案所造成之影響。第二種系統分析方式雖然可評估各種資源供應影響程度,但分析時必須考量各類型資源配置型態與其中資源數量組合變化,當模擬情境複雜時,其分析極為不易,本研究乃結合快速混亂基因演算法與營建離散事件模擬工具,發展一自動化建構各類資源供應模擬系統,以克服上述問題。 |
英文摘要 | Discrete-event simulation technique is useful in the design and analysis of construction operation process for the purpose of optimizing the overall performance of a construction system via simulating resource assignment schemes. Normally, the basic elements used in construction operation process simulation system are "Activity" and "Queue". Activity is use to model the task which consumes resources and takes time to perform. Queue acts as a storage location for resources entering an idle state. In the simulation system, Queues have to be created according to the ways of assigning resources to Activities. Conventionally, planner defines Queues according to his/her judgment by determining which and what amount of resources should be allocated to which activity. Consequently, various modeling schemes have to be examined to obtain the best simulation model. However, such a process of creating Queues and Activities is time consuming and requires iterations. This paper introduces a Fast Mess Genetic Algorithms (FMGA)-based modeling mechanism to automate the process of selecting the optimal modeling scheme. Case study shows that this new modeling mechanism along with the implemented computer program not only can ease the process of developing the optimal resource combination but also improve the system performance of the simulation model. |
