Activity Based Costing (ABC) is an(36)technique that allows an organization to determine the actual(37)associated with each product and service produced by the organization without regard to the organizational structure. This chapter explains some of the uses and benefits of Activity Based Costing. We use IDEFO(38)modeling in conjunction with ABC to enable more effective business(39)design decisions.In order to achieve the major goals of business process improvement, process simplification and improvement, FAA managers need to fully understand the cost, time, and quality of activities performed by employees or machines throughout an entire organization. ABC methods enable(40)to cost out measurements to business simplification and process improvement.A．computingB．campaigningC．programmingD．accounting

Data mining is an(66)research field in database and artificial intelligence. In this paper, the data mining techniques are introduced broadly including its producing background, its application and its classification. The principal techniques used in the data mining are surveyed also, which include rule induction, decision(67), artificial(68)network, genetic algorithm, fuzzy technique, rough set and visualization technique. Association rule mining, classification rule mining, outlier mining and clustering method are discussed in detail. The research achievements in association rule, the shortcomings of association rule measure standards and its(69), the evaluation methods of classification rules are presented. Existing outlier mining approaches are introduced which include outlier mining approach based on statistics, distance-based outlier mining approach, data detection method for deviation, rule-based outlier mining approach and multi-strategy method. Finally, the applications of data mining to science research, financial investment, market, insurance, manufacturing industry and communication network management are introduced.
