Abstract

In this paper we study a cross-docking problem minimizing the total flow time of inbound and outbound jobs. Using the theories and methodologies of scheduling, we formulate the problem into a two-stage scheduling problem and propose heuristics with worst-case performance analysis under parallel, uniform and open-shop machines, respectively. For each of problems studied, some polynomially solvable special cases are also introduced.
