I-Jini:一个适用于Internet的即插即用环境

The essentials which are indispensable for a plug-and-paly environment used on networkingare presented. Then Jini technology is introduced and some of its limitations are pointed out. This paperextends Jini' s idea to be used in a plug-and-play system for Internet,which is known as I-Jini. The ar-chitecture of I-Jini and a mechanism for its catalog service location are discussed in detail.

基于系统动力学的输配电网投资规划仿真分析

鉴于电网企业正从以最大程度满足用户侧需求为目的,逐步向同时追求保障供电安全和合理的投资经济效益的投资模式转变,通过确定电网投资与负荷增长、投资效益、政策因素和市场作用之间的相互影响关系及设定投资规划各子系统之间及系统内部的参数方程关系,构建了基于系统动力学方法的投资规划动态仿真模型,并以某地区电网发展数据为模型输入,对所建立的模型进行了多情景模拟分析,分别获得基准情景、负荷增长趋缓情景和市场力影响增加情景的仿真结果,验证了模型的有效性。
