Taking the advantage of the features of CASPF, a comprehensive evaluation indicator system for defining ordinary farmland as CASPF is established in this study, which covers 11 indicators, including slope, land plots connectivity, altitude, surface soil texture, and so on. With the help of the ideal-point method, ordinary farmland plots are sorted according to their evaluation scores in descending order. Based on the space analysis technique of GIS, high-ranking land plots are defined as CASPF reasonably.展开更多

The process started by defining the maintenance requirements of warship equipment. Next, a planning scheme was development for a maintenance network. An optimization target for the plan and indexes for assessment were established. Based on the above work, a simulation model was proposed with two layers: a base and a workshop. Dispatching rules were then formulated for the simulation. Experimental results proved the validity of the model and the dispatching algorithm. It was found that the model can solve the capacity evaluation problem for maintenance systems and provides a scientific basis for decision-maker to make decisions regarding equipment maintenance.展开更多
