物聯網是近年來熱門的話題，其中智慧環境控制更是主要議題之一。隨著時代進步，人們越來越注重生活品質，而環境空氣品質的好壞，對人體健康有極大的影響。為了實現室內環境舒適度的監控，使物件間能夠彼此交流，與實體世界溝通，並提供自動化的服務及管理，整合異質性物件將是極需解決的問題。為了解決此問題，我們需要導入流程工具，商業流程建模與符號(Business Process Model and Notation，BPMN)以方便對整個系統之建置、操作與管理。透過流程工具的協助，系統將可自動執行應用服務。除此之外，當需求改變時，管理員不需瞭解底層技術細節，只需調整或更新流程圖，即可應付較為複雜或多樣化的流程控制，進而滿足需求。
本論文中，我們將BPMN導入智慧環境系統。此系統以Raspberry Pi B+作為閘道器，並利用開源軟體(Open Source)Activiti為流程引擎，H2做為資料庫，實現監控室內環境之舒適度。我們設定三種系統會遇到的情況，透過對流程之操控來改變室內環境之狀況，並實際詢問使用者對各種改變之感受，以做為室內環境舒適改善流程之參考依據。實驗說明使用流程工具能有效且方便的操作智慧環境系統的應用。

Internet of Things (IoT) is a popular topic in recent years, in which ambient intelligence control is one of the main issues. Progresses along with the time, people emphasizes on quality of life. It has a great impact on human health whether the ambient air quality is good or bad. In order to monitor and make sure the environment comfortable, it's necessary to make heterogeneous objects communicated each other as well as interacted with the real world and provide a way of automatic management among these objects. To solve this problem systematically, the best way to implement and manage the system is utilized workflow tools, such as BPMN (Business Process Model and Notation) to describe the workflow of the system. With this way, the designed system can automatically perform applications with the pre-setting flows based on the business process tool. When the system requirements are changed, managers just need to modify the flow chart (process) without to understand the underlying technical details.

In this research, BPMN is used to describe the system which is used to monitor a varied environment under changing the different conditions. Many different sensors and actuators are employed to catch or control environment parameters. Three scenarios are considered in this research for evaluation the performance of using BPMN to create such an application system. It is shown that the system will show the response of the modified environment on the management system. The operator can catch the information of these modifications. The developer can also change their system configuration by changing the corresponding workflow via operating Activiti process engine.
