Abstract: A mobile terminal server (40) distributes information on an item put up for auction at an auction venue and bid price information to a smartphone (11), and every time the information on the item is changed, transmits empty data as well as a bid price that is automatically raised by a server (30) until it reaches the lowest acceptable price. The smartphone (11) receives the distributed bid price information and displays the bid price on a display unit (113). If the displayed bid price is a desired price, the user selects a participate mode, and places a bid by operating a place bid key (B3). The smartphone (11) maintains communication with the mobile terminal server (40) as long as empty data is transmitted. This prevents communication from being suspended and prevents a delay in display.

Abstract: A simulation method and system for simulation with excellent convergency for assets variation where variation elements of high dimensional number, at least over 102, are correlational to each other, and a method for generating pseudo random numbers used in the simulation. Upon simulation of assets variation, pseudo random numbers are generated by a computer such that the pseudo random numbers have a period over the product of the dimensional number of assets variation elements and the number of times to perform simulation necessary to converge simulation result to predetermined error, and have a uniform distribution in the respective variation elements. The generated pseudo random numbers are adjusted by the computer such that at least first moment and second moment of the variation elements match input data. The adjusted pseudo random numbers are used for simulating assets variation by the computer as values of the assets variation elements.

Abstract: An assets management method and system for enabling low-cost, highly-flexible, highly-reliable, efficient and safe assets risk management and earnings management, for geographically distributed users or managed assets data. Assets risk management and earnings management are performed for geographically distributed users and managed assets data based on different methods and/or standards for the respective users or managed assets, by utilizing inter-network communication typified by the Internet connection where the band is limited and the reliability and safety are poor. Data transmitted between a risk and earnings management apparatus provided in a central position and geographically distributed user terminals is compressed, encrypted, and provided with authentication key for each user or managed assets. The result of output based on the different methods and/or standards for respective users or managed assets is sent from the risk and earnings management apparatus to the user terminal.
