增材制造（AM）是一种先进的技术，其中通过使用先进的计算机辅助设计软件虚拟构建的数字化三维（3D）设计构建薄层材料来制造产品。这种自由制造极大地增强了设计的潜力，推动了可制造性的边界。本文的目的是提供一个决策框架，选择一个有效的组合的生产策略，包括替代AM和传统的制造技术。为此，提出了一个方法框架，该框架结合了多标准决策辅助（MCDA）和数据包络分析（DEA），用于在“集中”工厂的概念内确定最佳生产策略。有鉴于此，现代AM技术进行评估的一些选定的标准（如生产成本，交货时间，质量）连同现有的生产策略，涉及传统的生产方法，如注塑成型，数控加工等，所采用的框架被应用在一个现实世界的情况下，关于安全键盘聚合物外壳的生产。根据调查结果，现代增材制造技术为小批量生产提供了高效的制造解决方案，从而通过按订单生产战略和定制可能性提高了供应链的响应能力。此外，AM似乎也能够通过显着提高注塑模具的生产率来为传统的大规模生产系统做出贡献。拟议的框架不仅可以协助决策者选择最佳生产战略，而且还可以为不同的生产替代办法提供重要的基准。(C)2014年制造工程师协会。由爱思唯尔有限公司出版。保留所有权利。
Additive manufacturing (AM) is an advanced technology where products are manufactured by building up thin layers of materials from digitized three-dimensional (3D) designs virtually constructed using advanced computer-aided design software. This freeform fabrication enhances dramatically the potential of design, pushing the boundaries of manufacturability. The aim of this paper was to provide a decision-making framework for the selection of an effective portfolio of production strategies, including alternative AM and traditional manufacturing technologies. To that end, a methodological framework is proposed which combines multi-criteria decision aid (MCDA) and data envelopment analysis (DEA) for the determination of the optimal production strategy within the concept of "focused" factory. In this light, modern AM technologies are assessed for a number of selected criteria (e.g. production cost, lead time, quality) together with existing production strategies that involve conventional production methods, such as injection molding, CNC machining, etc. The adopted framework is applied on a real-world case regarding the production of security keyboard polymer housings. According to the findings, modern AM technologies provide efficient manufacturing solutions for small production volumes, thus enhancing supply chain responsiveness through make-to-order strategy and customization possibilities. Furthermore, AM seems capable to contribute also to traditional mass production systems, by improving significantly the productivity of injection molds. The proposed framework could not only assist decision-makers in the selection of the optimal production strategy, but it could also provide crucial benchmarks for different production alternatives.
