Any enterprise management ideas are to improve the economic efficiency, and reduce the cost is the enterprise to improve the economic benefits of the important factor. Activity based costing is to improve the economic benefit and reduce the cost.. Firstly, this paper expounds the basic principle, the core thought and the accounting procedure of ABC.. Then, applying the comparative analysis summarizes the activity-based costing method mainly has the following advantages: the activity-based costing to provide cost information is more reliable; can improve enterprise budget control; product sales and more rational pricing; can optimize the allocation of corporate resources; can improve business performance evaluation; business management strategy with inspiration. Followed by H company case analysis underlines the advantages of activity-based costing, but the homework cost method is not perfect, it also has to improve, the activity-based costing method does not apply to all enterprises, also not all enterprises have the application of activity-based costing. Through the case of the H company, the activity based costing is proved to be more suitable for the product variety and higher mechanization degree..

我也刚写完论文 希望能帮到你 Development of VB software for vehicle maintenance ground power supply monitoring center at present, China Railway is in the development stage, the project has been put into construction. With the increase in the number of the railway air-conditioned passenger car, passenger car servicing field with electrical problems have become increasingly prominent. DC power bus for maintenance when servicing field provides the ground power supply corresponding. At the same time, in order to save fuel costs, requiring power car power supply bus into the first ground power supply section. Need and supply current maintenance personnel in the use of ground power to train power supply before, first to the duty room for and receive the power supply cabinet key to carry out the power supply, after the completion of the keys returned to duty room. This mode of operation technology content is low, the tedious work, low efficiency, and the field distribution cabinet door key for the general, the existence of security risks. The most important is the ground power supply to the vehicle power supply in different time, the general electric meter is difficult to calculate a train or a is mainly responsible for the maintenance of maintenance of power, and management can not be timely grasp of on-site maintenance, inconvenience for fine efficiency management. This design using VB programming and RS-232 serial communication, the field data acquisition, display vehicle power real-time information to distinguish between different vehicles, electricity, generating statistical reports, and communication control system, automatic open and close and electricity appointment time functions to realize the power supply cabinet power switch. To realize the real-time monitoring of ground power supply.
