工业工程学（Industrial Engineering 简称IE），是从科学管理的基础上发展起来的一门应用性工程专业技术。工业工程的工作集中在设计、执行、评估、和改进集合人力、资金、信息、知识、厂房、设备、能源、物料、和流程的制造业生产系统。更多的工业工程师投身到诸如物流、信息、金融、医疗、服务、研发、国防等等众多产业当中从事系统分析与改进工作。

    在最初，工业工程的命名实际是科学管理 (IE之父：泰勒F.W.Taylor)，而在现在，在韩国等国家工业工程被称作产业工程，这更加符合它现在的应用范围。它最初是被应用于制造业，然而现在，它已经在其他相关的服务和产业得到广泛的应用。工业工程的也往往被称作运作管理（Operations Management）、系统工程、和工程管理等等。

    工业工程学（Industrial Engineering，简称IE）起源于20世纪初的美国，它以现代工业化生产为背景，在发达国家得到了广泛应用。现代工业工程是以大规模工业生产及社会经济系统为研究对象，在制造工程学。管理科学和系统工程学等学科基础上逐步形成和发展起来的一门交叉的工程学科。它是将人、设备、物料、信息和环境等生产系统要素进行优化配置，对工业等生产过程进行系统规划与设计、评价与创新，从而提高工业生产率和社会经济效益专门化的综合技术，且内容日益广泛。

Industrial engineering is a branch of engineering dealing with the optimization of complex processes or systems. It is concerned with the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, materials, analysis and synthesis, as well as the mathematical, physical and social sciences together with the principles and methods of engineering design to specify, predict, and evaluate the results to be obtained from such systems or processes. Its underlying concepts overlap considerably with certain business-oriented disciplines such as Operations Management, but the engineering side tends to emphasize extensive mathematical proficiency and usage of quantitative methods.

Depending on the sub-speciality(ies) involved, industrial engineering may also be known as operations management, management science, operations research, systems engineering, or manufacturing engineering, usually depending on the viewpoint or motives of the user. Recruiters or educational establishments use the names to differentiate themselves from others. In health care, industrial engineers are more commonly known as health management engineers or health systems engineers.
