In reverse supply chain under our study, there are four supply disruptions. As the source of the reverse supply chain, the supply disruption of used-products between end-consumers and collector will largely affect the profits of the reverse supply chain. In order to manage the profits of the reverse supply chain, we give an expanded stock-flow diagram with this supply disruption of the reverse supply chain by using system dynamics methodology, show the simulation results of collector’s profit, disassembly center’s profit, remanufacturer’s profit and the mean of their profits under different disruption periods. By analyzing the simulation results, we present a strategy to ensure the members positive profits. The strategy is adding another channel of purchasing used-products for the collector. We show the simulation results of the members profits and their mean after using the strategy, and give the suitable range of purchase quantity of used-products for the strategy.

Human computer interaction technology has been applied too much in Automated Teller Machine’s design, such as interface design. In this paper, we have done a survey on human computer technology for ATM and presented an investigation of the ATM’s design on the precious literatures. The user experience test and evaluation of the prototype are reviewed and discussed in details, and we find the defects and the improvement of the ATM’s design. In the end, we propose some suggestions and discussion in future works.
