In recent years, with the booming development of the sharing economy and the rapid development of technology, the food delivery model of crowdsourcing platforms has changed the behavior of restaurants delivery service. This article observes that in real life, crowdsourcing food delivery platforms often produce inefficient situations in which crowdsourced couriers gather to wait for customers to pick up meals during specific peak hours. In order to improve this situation, this article discuss the relationship between customers, platforms, restaurants, and crowdsourced couriers. The operation process interwoven by the four classes is used to think about ways to improve. This article provides a process improvement plan for the temporary food stand. The improved process after the implementation of the plan is compared with the process before the improvement, and the value of the improvement is found, and numerical simulation is used as verification. Put forward the reasons why the platform does not start to improve first, and also put forward the possibility of implementation motivation due to the large-scale platform.
