制造新产品的任务通常从设计师的办公桌开始，在那里一个想法被转化为一个物理模型的设计。虽然在一些行业中，计算机辅助设计是在这个初步阶段产生的，但在其他情况下，这往往是不可行的。因此，首先搭建了该产品的样机，并通过严格的测试验证了其性能。一旦这一设计获得批准，就必须提取产品的详细物理特性，以便于重新设计或制造。逆向工程就是实现这一点的过程。它可以广泛地定义为从现有的实物产品创建模型(通常是基于计算机)。图1提供了反向工程在工业环境中的一些应用程序的快照。从图1可以看出，逆向工程可以用于创建CAD模型，原因有很多，从尺寸评估到设计修改。随着廉价计算能力的出现，逆向工程的计算机辅助系统已被证明可将产品设计和制造生命周期缩短40%以上[1]。因此，与这一领域相关的技术得到了越来越多的应用，成为一个活跃的研究领域。虽然工业工程(IE)是一个年轻的职业，但它已经迅速超越了早期成功的工作测量，作为提高生产率的一种手段。在当今竞争激烈的全球市场中，工业工程师使用诸如并行工程等较新的概念来响应对更高灵活性和更快响应时间的需求。逆向工程是帮助工业工程师实施并行或同步工程等现代概念的有效工具，因为它有助于缩短从设计到制造的交付期。此外，工业工程师经常被要求在不同的环境中应用他们的综合技能。逆向工程还可以在许多不同的环境中使用：从制造到医药，这使得该工具特别适用于IE专业。
The task of manufacturing a new product usually begins at the designer's desk where an idea is transformed into a design for a physical model. Although, in several industries, computer-aided designs are generated at this preliminary stage, this is often not feasible in other cases. Therefore, a prototype of the product is first built, and its performance verified through rigorous testing. Once this design is approved, the detailed physical characteristics of the product have to be extracted to facilitate its redesign or manufacture. Reverse engineering is the process by which this is done. It can broadly be defined as the creation of the (typically computer based) model from an existing, physical product. Figure 1 provides a snapshot of some of the applications of reverse engineering to an industrial environment. It can be seen from Fig. 1, that reverse engineering can be used to create CAD models for a variety of reasons ranging from dimensional evaluation to design modifications. With the availability of inexpensive computing power, computer aided systems for reverse engineering have been shown to shorten the product design and manufacturing life cycle of products by over 40%[1]. Thus, technologies associated with this area are finding increased application and this has become an active research area. Though industrial engineering (IE) is a young profession, it has quickly moved beyond the early successes of work measurement as a means for productivity improvement. In today's competitive global marketplace, industrial engineers use newer concepts such as Concurrent Engineering in responding to the need for increased flexibility and faster response times. Reverse Engineering is an effective tool in helping industrial engineers implement modern concepts such as Concurrent or Simultaneous Engineering since it helps shorten the design-to-manufacture lead time. Also, industrial engineers are often called to apply their integratwe skills across a diverse spectrum of environments. Reverse Engineering can also be used in many d~ fferent environments: from manufacturing to medicine, making this tool especially relevant to the IE profession.
