        报告内容简介：we address a novel generator scheduling problem with split pick-up and repeatable delivery under an unplanned base station power outage. state of charge (soc) function and generators paralleling are considered for continuous battery charging. a pattern-based formulation is firstly proposed for problem description and then enhanced pattern-based formulation is designed to strengthen its effectiveness. the branch and price algorithm is well developed for solution, which including a tailored dominance criteria in labelling algorithm and a primal heuristic. to explore the efficiency of proposed algorithm, we test it on both actual-based instances and generated instances. computational experiments demonstrate that the modifications and implementation features lead to substantial improvements in computing time and solving performances.
