講座內(nèi)容:
This talk considers a two-agent scheduling problem in which each agent has a set of jobs competing with the other agent's for the use of m unrelated parallel machines. Each agent desires to minimize a certain scheduling criterion related to the completion times of its jobs. The overall objective is to minimize the total completion time of the jobs of one agent, while keeping the weighted number of tardy jobs of the other agent within a given limit. We introduce a novel column generation approach for this problem to keep stabilization and embed it into a branch-and-price procedure. A greedy heuristic is used to obtain a set of initial columns to start the in-out column generation. The pricing subproblem in the column generation is formulated as a single-machine scheduling problem solved using dynamic programming techniques. An efficient branching strategy compatible with the pricing subproblems is also proposed. Extensive computational results using randomly generated data demonstrate superior performance of this branch-and-price procedure to the standard method.
