Application of optimization methods in e-shopping

The subject of the thesis is the optimization of one the key processes in a book e-shop, namely delivery of goods from suppliers. In particular, we focus on the problems of selection of suppliers and the subsequent route optimization in daily pick-ups of orders. The proposed solution uses a combination of two mixed integer programming models. The model for supplier selection was designed so as to reflect the empiric approaches that are currently employed in the e-shop; the model for route optimization is a modified version of the canonical travelling salesman problem. On the basis of achieved results, we presented effective procedures for solving both of the aforementioned problems and suggested their implementation into the e-shop's enterprise resource planning system.
