This article presents the application of an expert system (ES) prototype as an intelligent tool for preliminary diagnostics of energy efficiency (EE) potential in Brazilian industrial plants and knowledge management (KM) in organizational environments, aimed especially to small- and medium-sized enterprises. The prototype provides the diagnostics rationale through a module for an explanation to support the decision making and provide insights regarding the adoption of EE actions. The knowledge base required by the prototype is built from the expertise and experience of a group of experts in EE and professionals from the industrial sector. The knowledge acquired from this interaction is represented in the form of rules, which are computationally implemented through a well-known tool for developing ES. Then, the resulting prototype is validated by the same group of multidisciplinary experts. Two different applications are presented to demonstrate the possibilities of EE improvement in industrial plants. These applications also show the ES as a valuable resource for organizational KM. In such a context, the ES creates a permanent corporate memory regarding EE, so that the access to this knowledge is independent on the availability of the human experts in the area. The ES also turns EE expertise into lasting value through sharing and retention actions, contributing to further improvements and processes continuity.

本文介绍了专家系统（ES）原型的应用，该工具可作为智能工具对巴西工厂的能源效率（EE）潜力进行初步诊断，并在组织环境中特别针对中小型企业的知识管理（KM）企业。该原型通过一个模块提供诊断依据，以进行解释以支持决策并提供有关采用EE行为的见解。原型所需的知识库是基于EE专家和工业领域专家的专业知识和经验建立的。从这种交互中获得的知识以规则的形式表示，这些规则通过用于开发ES的众所周知的工具以计算方式实现。然后，得到的原型得到了同一组多学科专家的验证。提出了两种不同的应用，以证明在工业工厂中提高EE的可能性。这些应用程序还显示ES是组织KM的宝贵资源。在这种情况下，ES会创建有关EE的永久性公司记忆，因此对这一知识的访问独立于该地区人类专家的可用性。ES还通过共享和保留行动将EE专业知识转化为持久的价值，从而有助于进一步的改进和流程的连续性。在这种情况下，ES会创建有关EE的永久性公司记忆，因此对这一知识的访问独立于该地区人类专家的可用性。ES还通过共享和保留行动将EE专业知识转化为持久价值，为进一步的改进和流程的连续性做出贡献。在这种情况下，ES会创建有关EE的永久性公司记忆，因此对这一知识的访问独立于该地区人类专家的可用性。ES还通过共享和保留行动将EE专业知识转化为持久价值，为进一步的改进和流程的连续性做出贡献。
