The more efficient use of by-product gas has always been a hot issue in the iron and steel making process. The gas generated during production process is stochastic and hardly predicted accurately. Specifically, how to regulate the supply of by-product gas from gas holder to power plant in the scheduling period to maximize the total profit of gas reutilization is present work. In response to this objective, online algorithm will be applied here to analyses the optimal strategy, which manages the by-product gas supply scheduling in term of online strategy and competitive analysis. We give the competitive ratio’s lower bound of the problem, and analyze the properties of algorithms, then give the QEW-algorithm with a competitive ratio equals to γ/(γ-β). The results of the study have guiding significance and reference value to decision makers facing the actual production process.

Many processes in the iron and steel making industries emit carbon monoxide, which causes a variety of toxic effects on human health, such as fatigue, impaired memory, headache, and nausea. At elevated exposure, carbon monoxide poisoning may lead to loss of consciousness and death. Therefore, the current study has been carried out to investigate the occupational exposure of randomly selected fifty-eight employees of Pakistan Steel Mills to the carbon monoxide. The selected employees were from 10 different facilities of the Pakistan Steel Mills, who were working in two different shifts viz. nightshift and dayshift, each of twelve hours. Thirty employees from nightshift and twenty-eight employees from dayshift were monitored for their exposure to carbon monoxide. The instrument was logged to measure the employee’s exposure to carbon monoxide with 1-minute interval. The study reveals that the employees, working in the Raw Materials Production Plant during nightshift were exposed to the highest mean concentration of carbon monoxide while those working in Oxygen Plant during nightshift were exposed to the lowest mean concentration of carbon monoxide. According to study, the highest recorded exposure was found near Blast Furnace during dayshift. The employees’ exposure to 98th percentile concentration of carbon monoxide in different facilities of the steel mills has also been analyzed. The employees’ exposure to carbon monoxide during commuting from home to their workplace has also been investigated.DOI: http://dx.doi.org/10.3126/ije.v3i4.11730      International Journal of EnvironmentVolume-3, Issue-4, Sep-Nov 2014Page: 44-56
