A Model for Design of Human Activity Systems

A background is given to the common failures of management information systems and the authors' view of the causes behind these failures. There seems to be a lack of effective methods for analyzing information requirements. Different scientific methods are discussed as to their propensity for analyzing the information requirements. The importance of the systems design approach instead of the system improvement approach is emphasized. The concept of Human Activity Systems is discussed and an analysis of the interdependence of the soft and hard parts of these systems indicates that an integrated view is necessary. A methodology based on a systemic and systematic analysis of the information requirements in an organization is proposed. This methodology focuses the settings of the decisions on all levels in organizations and also indicates organizational discrepancies and information imbalances. The methodology can be regarded as a dynamic, learning system.     

Market Share Model of Price and Advertising Combined Game in Duopoly

The marketing share model of price and advertising in a duopoly market was studied in this paper. Market response curves of price and advertising were presented to calculate the reasonable range based on the market forecast results. The interaction effect of price and advertising was considered,and the game theory was applied to a two-stage price and advertising competition which involved the market share model. A marketing decision support system (MDSS) was developed and simulation data was provided to give the solutions. The operation results show that the leading enterprise makes higher price,spends more on advertising,and earns more profit,while the small-scale enterprise has to lower the price,spend less on advertising,and has slightly higher profit rate. The system is shown to be adaptable to a wide variety of realistic situations.

基于蒙特卡罗的消费投资决策模型研究

将消费和投资放在一个跨期最优化框架下,提出了基于蒙特卡罗风险评估的消费投资决策模型。首先,建立个体效用函数、劳动收入、跨期预算约束、投资机会及市场摩擦因素之间的数学表达式。然后,考虑劳动收入风险、投资收益风险,建立消费投资组合动态优化模型。最后,通过一个实例阐明所提出模型能更加有效地刻画实际市场中的消费投资情况,证明所设计算法的有效性。
