Abstract: The construction of intelligent cigarette factories is a crucial initiative to advance the high-quality development of the cigarette industry. To address the current issue that cigarette smart factory construction is mainly focused on local dot-point applications and lacks a systematic technical architecture and evolution path, based on reviewing industry and national intelligent manufacturing standards and literature related to cigarette manufacturing, a system architecture for cigarette intelligent factory construction was constructed from the perspective of "technology and business, value synergy". First, the development connotation of smart cigarette factories was defined with factory digitalization, production intelligence, and lean management as its core dimensions; Second, a technical architecture for cigarette intelligent factories comprising the perception and execution layer, interconnection layer, data governance layer, and business application layer was established. Third, a three-stage progressive development pathway from intelligent production units to intelligent workshops and ultimately to smart factories was proposed. In addition, key technologies tailored to the specific business requirements of cigarette manufacturing enterprises were analyzed, including integrated production management and control based on multi-source data collaboration, artificial intelligence-enabled cigarette manufacturing process optimization, and intelligent operation and maintenance of cigarette manufacturing equipment. The results indicate that the proposed architecture can realize an evolutionary process from local optimization to system integration and ultimately to holistic intelligence, providing a theoretical framework and technical reference for the transformation of smart cigarette factories from single-point intelligent applications toward system integration and factory-wide intelligence.
