SEISMIC HAZARD EVALUATION IN UNDERGROUND CONSTRUCTION: THEORY AND PRACTICE

摘要

The nature of Web systems is substantially different from more conventional software systems. They are developed in shorter timeframes. often act as the direct interface between multiple stakeholders, meet a more generic set of requirements, and generally serve a less specific user group. They are often developed very quickly from templated solutions, using coarse-grained authoring tools, and by the efforts of a multi-disciplinary team. There is often considerable uncertainty on the pan of the client as to their own requirements. The importance of defining the objectives of the system during the early stages of a project are generally acknowledged to be important, but access to the tools and templates can encourage developers to build too early. Often requirements are inadequately documented, or only emerge during development, or change as development proceeds.
