传统工程学的大部分内容都是从广义上分析系统的行为。传统类型的典型工程问题是：当（应力、热、光、电磁）波通过介质或遇到障碍物时会发生什么？裂缝对结构强度的影响是什么？一个结构如何对一个力作出反应？复合材料的强度是多少？在过去的二十年里，越来越明显的是，工业和学术工程中实际出现的问题不符合传统的模式。在新的问题中，已知量和未知量的作用发生了变化，而且常常颠倒过来。这样，我们就不必给出一种介质，并被要求去发现扰动在穿过介质时是如何受到影响的，我们知道扰动发生了什么，并希望利用这些信息来分析介质。这些角色的变化导致了新学科的制定：X射线，光学，热或钻孔层析成像;声学，空气动力学或电磁学的形状优化;裂缝和障碍物的检测;有限元模型更新;材料建模;等等。这本杂志是关于这些问题的研究，因为它们出现在工程，因此标题。
Much of traditional engineering has been concerned with analysing the behaviour of systems, interpreted in a broad sense. Typical engineering problems of the traditional type are: what happens to (stress, thermal, optical, electromagnetic) waves when they pass through a medium, or meet obstacles? What is the effect of a crack on the strength of a structure? How does a structure respond to a force? What is the strength of a composite material?During the past two decades it has become increasingly apparent that the problems which actually arise in industrial and academic engineering do not fit into the traditional mould. In the new problems, the roles of known and unknown quantities have been changed, often being reversed. Thus instead of having given a medium and being asked to find how a disturbance is affected as it passes through it, we know what happens to the disturbance and wish to use the information to analyse the medium. These changes in roles have led to the formulation of new disciplines: x-ray, optical, thermal or borehole tomography; shape optimisation in acoustics, aerodynamics or electromagnetism; detection of cracks and obstacles; finite element model updating; material modelling; etc. These, and the other related disciplines, have come to be grouped under the general title Inverse Problems. This journal is concerned with the study of such problems, as they arise in engineering, hence the title.
