中文摘要：

产品能耗限额对于加强产品制造过程能量消耗管理、监控和提高能量效率均十分重要。目前,钢铁、化工等流程制造行业的产品能耗限额制定已有不少成熟方法,并从国家层面制定了一些主要产品的能耗限额指标;但对于量大面广的离散制造业产品,由于其能耗规律的复杂性和动态变化性,其能耗限额制定非常困难。目前我国还没有一项国家层面的离散制造业产品能耗限额。基于离散制造业产品制造能耗特点的分析,揭示离散制造业产品能耗限额制定的分布式多数量制造系统关联性等复杂特性。在此基础上,针对规格品种繁多的一般产品即绝大多数产品,提出产品与制造系统的关联能耗限额制定策略;针对个别量大面广、能量消耗总量巨大、制造设备、工艺和制造流程相对比较成熟和确定的特定产品,提出统一能耗限额制定策略;并给出关联能耗限额制定和统一能耗限额制定的具体策略。上述特性和策略为离散制造业产品能耗限额制定这一难题提供了一种总体解决思路。

英文摘要：

Product energy consumption allowance（PECA）is very important for the management and monitoring of energy consumption and the improvement of energy efficiency in product manufacturing process. A number of methods currently have been successfully used to make PECA for process manufacturing industry including steel,chemical industry and so on. Especially,some national standards of PECA for several main products have been published in China. However,as for discrete manufacturing products with great quantity,it is very difficult to make their PECA due to the complexity and variety of their energy consumption processes. As a result,no national PECA for the discrete manufacturing industry is now available. By way of analyzing the energy consumption characteristics of discrete manufacturing product,a number of complex characteristics of making PECA are revealed,such as the relevance of PECA and distributed multiple manufacturing systems. Based on these characteristics,a strategy forestablishing product energy consumption allowance in discrete manufacturing industry is proposed by classifying these products into two types,general products and specific products. For general products,the related PECA making strategy is presented by combining the PECA with the corresponding manufacturing system. For a specific product which is in huge quantity and with a large volume of energy consumptions,and whose manufacturing processes and equipment are relatively certain,the uniformed PECA making strategy is suggested. Moreover,the specific procedures of above two strategies are detailed. These characteristics and strategies provide a general solution to make PECA for discrete manufacturing industry.
