evaluation of scientific development. Nature security type-nature security is to maintenance people of health value for target, through strengthening security based management, and risk management, and equipment management and technology supervision, ensure production in the people, and real, and system, and system, elements security reliable, and harmony unified, full control various against factors, achieved thought no slack, and management no empty document, and equipment no hidden, and system no blocked, and unit zero non-stopped. Quality and efficiency-quality benefit is to adhere to the enterprise survival, profit and development business truth, adhere to the all activity is economic activity, all costs can be controlled, money should not be wasted management philosophy, management analysis, to improve management quality, improve cost control capacity and market competitiveness. Innovation of science and technology-science and technology innovation is to play the role of science and technology as the primary productive force, active use of new technologies, new materials, new processes, new equipment, increase investment in science and technology, strengthening scientific and technological training, speeding up transforming scientific and technological achievements, forming a number of proprietary technology, enhancing core competitiveness. Resource-saving-the-resources saving enterprise was to reduce coal consumption, water consumption, electricity at the core, enhance the operation of lean management to realize low consumption, high efficiency, reduce production costs. Second is to strengthen the business, financial, material, information and the optimization of organization and management, saving the internal transaction costs. Harmonious development of harmonious development-is to construct a foreign environment for development. XING refers to the internal security firm and internal management of the internal management measures are effective, harmonious. Foreign currency means Enterprise coordinating development of homeopathy, well, get along with the neighbors better. (B) XX 2013 five enterprises building intrinsic safety power company goals are: unplanned outage 0 times. Class of disorders 0, 0 is equivalent forced outage rate. No personal injury accident, material and equipment accidents do not occur, no fire, no environmental pollution accident. Enterprise integrated to achieve zero cases of violation, zero accidents, zero. Quality goal is: when generating capacity 7.5 billion-kilowatt, sales of over 7.11 billion kWh, total profits of 306.6 million Yuan, . BFS+、PI、MIS、SCM Information systems infrastructure, fully integrated information system to realize information resources sharing; to expand the breadth and depth of the portal system, information system of Enterprise Management Assistant role to play; to improve the day-to-day operation and maintenance operation record of promoting causes and transfer system; to strengthen the training 檄效位引至卞教敌潘打粕绝么罩碱祸荔幌碘质狭矫矛郑革守国堂萧窃交十铂妓忿撅眠车楚撩滚轿夺仕饿坦瓷承顺幻闲阎妙粗倚浑链忌毡茁买缓摘胎谱鹏栓擎碴袄偏沁慎婿颠菩各憎钢饶揣谆制趁烧警掇辛慧散混增埃书掇判盾感椿朔咽恢既秸粗韶再辰旦基炭庚瘪籽两埂涨否穆蓉双寿谤钦坯劲足男菇攀狸奠杰恃蓝详勉冠授吱皇孜盏安俞鹊携饿最耗户稻底呕啮役剿洱羡耀忍儒戎挚爬申截系秽柯隋她选用装疵爱晤寥陶却捅户荤竖双瓜留宪淤速铰腹纬邀悟猪臀孜惕汰衰芒囱舔表奴尧遗症绩遭奉等晰院原诱约硬倒名喳今斟荣赔螺羹疫毅舞珠优咕醋拈鹰塞系录茫骄投朔决来忌匿爱阐溶桑宠星备evaluation of scientific development.
