Accurate forecasting of the undecided population in a public opinion poll

The problem of pollsters is addressed which is to forecast accurately the final answers of the undecided respondents to the primary question in a public opinion poll. The task is viewed as a pattern‐recognition problem of correlating the answers of the respondents to the peripheral questions in the survey with their primary answers. The underlying pattern is determined with a supervised artificial neural network that is trained using the peripheral answers of the decided respondents whose primary answers are also known. With peripheral answers as inputs, the trained network outputs the most probable primary response of an undecided respondent. For a poll conducted to determine the approval rating of the (former) Philippine president, J. E. Estrada in December 1999 and March 2000, the trained network predicted with a 95% success rate the direct responses of a test population that consists of 24.57% of the decided population who were excluded in the network training set. For the undecided population (22.67% of December respondents; 23.67% of March respondents), the network predicted a final response distribution that is consistent with the approval/disapproval ratio of the decided population.

Decision trees for forecasting

Recent years have seen an increasing cross-fertilization between the fields of decision analysis and forecasting. Decision-analytic models often require forecasts as inputs, and aspects of the Bayesian decision-theoretic framework underlying decision analysis have proved useful to forecasting, particularly in contexts where subjective judgemental inputs are required. This paper describes the use of decision tree analysis for forecasting and illustrates its use for corporate divisional forecasting and planning. A specialized decision-analytic technique, acts as events, is also described and illustrated to forecast a new product's earnings. Conclusions are drawn about the applicability of decision analysis for forecasting.     

水电工程规划设计方案的自动生成及评价

马尔科夫人才规划模型与应用研究

介绍了马尔科夫人才规划模型，提供了一种可以用来进行组织的内部人力资源供给预测的方法，其基本思想是找出过去人事变动的规律，以此来推测未来的人事变动趋势．这一方法不仅可以处理员工类别单一的组织中人力供给的预测问题，也可以解决员工类别复杂的大型组织中的内部人力供给预测。     

基于长期计划的动态给水管网优化设计模型

鉴于给水管网的优化设计的重要作用，提出了更符合实际、准确度更高的基于长期计划的动态给水管网优化设计模型。其目标函数中，动力费采用与时间相关的函数计算，折旧大修费采用与管段损坏率相关的函数计算，并建立了相应的动态优化设计模型。可以更精确地得出基于长期计划考虑管网优化设计结果。
