约基霍勒技术公司(Jockey Hollow Technologies)作了一次调查,结果表明,美国最大的30家化学公司中有70％左右正在研制某种人工智能系统,主要是专家系统。在接受调查的公司中有60％的公司正在研制程序控制系统,其它公司正在研制较大型计算机系统。过去两年已有95％以上的专家系统运用成功。据程序技术公司(Process Technology)的莫伦坎普(R·Mollenkamp)说,真正的专家系统应能处理不确定性的或不完整的情报。纽约州霍 A survey conducted by Jockey Hollow Technologies showed that about 70% of the 30 largest chemical companies in the United States are developing an artificial intelligence system, mainly an expert system. Sixty percent of companies surveyed are developing program control systems while others are developing larger computer systems. Over 95% of expert systems have been successfully used in the past two years. According to R. Mollenkamp of Process Technology, true expert systems should be able to handle uncertain or incomplete intelligence. New York State
