This paper has two different aims: presenting the problem of target-based computer-assisted orchestration and introducing a new computational framework to solve it, called Orchidea. After the definition of the static and the dynamic versions of the problem, a historic perspective will be discussed. The cultural context of assisted orchestration will be examined, with particular attention being given to spectral music. In the second half of the paper, the Orchidea framework for dynamic target-based computer-assisted orchestration will be introduced and discussed in detail. After the discussion of the design principles and the philosophy behind this framework, all its components will be studied. Finally, possible steps for the future of computer-assisted orchestration will be presented.

本文有两个不同的目标：提出基于目标的计算机辅助编排问题，并引入一种新的计算框架来解决该问题，称为Orchidea。在定义了问题的静态和动态版本之后，将讨论历史视角。将研究辅助编曲的文化背景，特别关注频谱音乐。论文后半部分将详细介绍和讨论基于动态目标的计算机辅助编排的Orchidea框架。在讨论了该框架背后的设计原则和哲学之后，将研究其所有组件。最后，将提出计算机辅助编排未来可能采取的步骤。
