HVAC Control in the New Millenniumtionality and flexibility.The ideal automated plant takes in raw materials or fuel at one endand outputs finished products at the other end, without the aid of humanlabor. Humans may provide special talents in problem solving anddecision making. They will set up a supply of raw materials and tell theplant what is to be produced and arrange for transport of the finishedproducts.The automated plant may consist of equipment, robots, and materialhandlers which are computer controlled. Much of this equipmentwill have built-in computers. The management within the automatedfactory will be by expert systems.Supervisor computers will schedule equipment computers, while acentral management computer will schedule the supervisor computers.Human management will control the central management computer.The expert systems will allow the plant to reroute production arounddefective machines or to start secondary production systems. All thecomputers and equipment used in the automated plant will have a highlevel of intelligence.In its early stages, the automated plant’s ability will be to producea specific product. Later, this will include the ability to produce morethan just one product or a closely related family of products.Understanding Human LanguagesSeveral areas of artificial intelligence deal with understandinghuman languages. These include voice or speech recognition, and naturallanguage understanding. Voice or speech recognition deals with convertingthe spoken language of humans into recognizable patterns forthe computer. Natural language understanding involves accepting commandsin a human language, such as English, and translating thesecommands into the computer’s own machine language. A voice recognitionsystem or a keyboard may be used to get the words into thecomputer. Then the natural language understanding program finds themeaning for the words.Computer machine languages are precise while human languagestend to be inexact. The same English sentence conveys different meaningsto different persons. The same person may also give different meaningsto the same sentence under different conditions.
