Agent不仅要具有逻辑推理能力，还应当具有类似人类的情感能力。通过对情感理论的分析，提出了一个基于OCC的Agent情感模型，使Agent能够模拟像人类一样的认知能力和情感能力，从而行为决策更加智能。通过模型在虚拟环境角色中的应用结果，验证了此模型的合理性。关键词:情感计算；情感理论；OCC 模型；情感模型；Abstract—Agent not only needs to have logical reasoning but also should have emotions like human. This article presents an Agent\'s affective model based on OCC in accordance with affective theory, which allows the agent to simulate cognitive ability as well as affective ability like human and thus has more intelligent decisions for behaviors. Through applying the model to the role populating in the virtual environment, the results prove the model\'s validity.Key words: affective computing; affective theory; OCC model; affective model
