摘　　要：以钢铁企业副产煤气为研究对象,基于在线理论,考察其在线均衡分配问题.在生产过程中,决策者在每个时期决策煤气的供应量,目标是使得在各时期煤气供应尽可能均衡平稳.基于合理假设,建立煤气均衡分配模型,对于均衡区间未知的问题,分析了离线情形的特殊性质,以及不同煤气产生序列情形下的在线特征;对在线问题设计了在线二分策略,并用最坏情形法证明了其竞争比为(1+3M/m)/4.本研究为企业生产中副产品的均衡分配和利用提供了一定的思路与理论借鉴.This paper develops a new framework for the analysis of byproduct gas supply in iron and steel industry. Based on the online theory, this paper studies the online balance assignment problem of the byproduct gas. In the production process, the online decision maker makes decisions to balance the supply of byproduct gas in the online case. Under some reasonable assumptions, the paper constructs a balance assignment model of the byproduct gas to solve the balance range unknown problem. First, this researcher attempts to analyze the special nature of the ofitine case and the characteristics of the online case under different scenes. Then the paper designs an online balance strategy with a competitive ratio of （1 ＋ 3M/rn）/4 without the knowledge of supply interval. This study provides some ideas and theories for the balance assignment and use of the byproduct in manufacture industry.
