Unmanned Air Vehicles (UAVs) have the ability to execute missions that include detecting and destroying the targets. The Simian simulator developed at NDSU performs complex motion calculations for moment - moment flight and delivers effective inter-agent communication for all the UAV’s. Scenarios that focus on the strategy plan and perform calculations have been, developed to carry out the mission. The goal of this paper is to address the tasks of starting servers, manually writing the required xml files to describe scenario to the simulator and launch simulation in the existing Simian system. Simian Plus is, designed and implemented to ease the process of building and launching simulation. It is, aligned to the key principle “Open- agent architecture” of Simian.
