配分 also means distribution or allocation, but often emphasizes dividing something into portions and handing them out, whereas 割り振り focuses more on assigning roles or tasks according to a plan.
割り当て is very similar and often interchangeable, but 割り振り can imply a more systematic or scheduled distribution, while 割り当て can be used for simpler assignments or quotas.
Compound of 割り (wari, 'split, divide') and 振り (furi, 'assign, distribute'). The combination conveys the idea of dividing and then assigning portions.
