摘要：

WEAVE是位于西班牙拉帕尔马的威廉·赫歇尔望远镜主焦点的新宽视场光谱设施。它的光纤定位器是摄谱仪~960光纤复用器精确定位的关键。为了最大限度地分配光纤，WEAVE使用了一种称为配置的模拟退火算法，该算法将光纤分配给视场中的目标。我们使用中层WEAVE-LOFAR字段的子集对算法的行为进行了分析，并调整了优先级分配算法，以优化每个字段分配的总纤维，以及将纤维分配给更高优先级的科学目标。输出分布已被检查，调查的影响，为WEAVE科学团队。

英文摘要：

WEAVE is the new wide-field spectroscopic facility for the prime focus of the William Herschel Telescope in La Palma, Spain. Its fibre positioner is essential for the accurate placement of the spectrograph's ~960-fibre multiplex. To maximise the assignment of its optical fibres, WEAVE uses a simulated annealing algorithm called Configure, which allocates the fibres to targets in the field of view. We have conducted an analysis of the algorithm's behaviour using a subset of mid-tier WEAVE-LOFAR fields, and adjusted the priority assignment algorithm to optimise the total fibres assigned per field, and the assignment of fibres to the higher priority science targets. The output distributions have been examined, to investigate the implications for the WEAVE science teams.
