ABSTRACT: Scattered storage means an item can be stored in multiple inventory bins. The
scattered storage assignment problem based on association rules in Kiva mobile
fulfillment system is investigated, which aims to decide the pods for each
item to put on so as to minimize the number of pods to be moved when
picking a batch of orders. This problem is formulated into an integer programming
model. A genetic algorithm is developed to solve the large-sized
problems. Computational experiments and comparison between the scattered
storage strategy and random storage strategy are conducted to evaluate the
performance of the model and algorithm.
