Design of Intelligent Control Software for Mini-Earth

In this paper, we describe the design of intelligent control software required for operating the Closed Ecology Experiment Facilities (CEEF) that we call Mini-Earth. We will develop intelligent control software by reconfiguring functions of a Control Computer System (CCS) for controlling the CEEF into three layers that consist of planning & scheduling, task, and control levels. In the last half of this paper, we will focus on the planning & scheduling level, and describe the operation scheduling problem of a CEEF gas circulation system using a Planning and Scheduling Language (PSL) to develop an Operation Schedule Interactive Generation system (OSIG).
