报告摘要：
In this talk, I introduce optimal positioning problems in two-dimensional lamp systems considering the system reliability. Suppose n lamps are used to cover a service area, where each lamp can cover a circle area with a radius r. The lamp can be failed with some probability and the system is working when working lamps cover the whole service area without dark area. The system reliability is the probability that the whole area is covered by working lamps. The lamp positioning problem is to determine the positions of lamps in the service area and the system reliability is used as an optimization criterion. Firstly, I explain how to calculate the system reliability in two dimensional lamp systems. Secondly, heuristic methods are proposed to determine the lamp positions and the performance of the heuristic methods is investigated by numerical examples. Finally, some promising research topics for future studies are discussed.
