采用统计调查与统计分析的方法,推算出我国铸件市场发展的历史数据。在分析研究铸件市场状况和特点、市场需求预测方法、铸件市场历史发展变化规律及影响因素的基础上,建立了我国铸件市场需求量的综合预测数学模型:Y`t=K[0．283Yh(t)+0．717Y_x(t)],并进行了预测。根据预测结果,进行了较为详细的分析,并进一步探讨了铸造科研和生产技术是否适应的问题。提出了为适应铸件市场需求发展宜采取的重大措施建议。
Using the methods of statistical investigation and statistical analysis, the historical data of the development of China’s casting market are deduced. Based on the analysis of the status and characteristics of the casting market, the forecast method of the market demand, the history of the casting market and its influencing factors, a comprehensive mathematical model of the demand for the casting market in China is established: Y `t = K [0.283Yh ( t) + 0.717Y_x (t)], and predicted. Based on the forecast results, a more detailed analysis was carried out and the question of whether the foundry scientific research and production technology was adapted was further discussed. Proposed to meet the needs of the casting market development should take major measures to be taken.
