  With the increasing market penetration of battery-electric buses into urban
bus networks, practitioners face many novel planning problems. As a result, the
interest in optimization-based decision-making for these planning problems
increases but practitioners' requirements on planning solutions and current
academic approaches often diverge. Against this background, this survey aims to
provide a concise guide on optimization-based planning approaches for
integrating battery-electric buses into urban bus networks for both
practitioners and academics. First, we derive practitioners' requirements for
integrating battery-electric buses from state-of-the-art specifications,
project reports, and expert knowledge. Second, we analyze whether existing
optimization-based planning models fulfill these practitioners' requirements.
Based on this analysis, we carve out the existing gap between practice and
research and discuss how to address these in future research.
