　　為了能快速滿足消費市場需求且節省設備成本，批次工廠裡的物料常藉著複雜的管線網路在不同單元設備之間輸送，經過不同的處理後製造出較高價值的產物。在傳統上，傳送物料的操作步驟是以人工方式合成的，然而這樣的作法不但沒有效率，並且容易出錯。本論文根據派屈網(Petri Net)發展出以有系統化的方法自動產生出輸送物料的操作步驟。除此之外，由於在輸送物料的同時，難免會有沉澱物在管內中產生，因此本研究的另一個目標為發展以派屈網為基礎的方法來產生清洗管線網路所需的操作步驟。

　　In order to quickly satisfy the demand of consumer market and save equipment cost simultaneously, the raw materials in a batch plant are routed through complex pipeline networks among shared processing units and successively converted toward higher-valued products. Traditionally, the task for synthesizing a feasible set of operation steps for material transfer is carried out manually on an ad hoc basis. However, this approach is very inefficient and the resulting recipes are often error-prone. The aim of the thesis is to develop a systematic method with Petri Net models for automatic generation of operating procedures. In addition, since sediments could deposit on the inner surface of pipeline while transferring material, it is also the intention of this work to conjecture a Petri-net based technique to synthesize operating procedures for cleaning/purging the pipeline networks.
