碩士 === 國立交通大學 === 工業工程與管理系 === 87 === A bid-opening system for trading eggs on Internet is designed and implemented under the polynomial secret-sharing algorithm. Essentially the bid-opening process is to retrieve the data from different secrete-sharing site servers and find the bid winners. At the design phase, the bid-opening process is specified by IDEF0 technique. Then the corresponding database for storing the secrete-sharing data is designed using minimal cover theorem and IDEF1X technique. At the implementation phase, many software modules have to be implemented to execute the four major tasks in finding the bid winners. Task one recovers the true transaction data by refining the mixed secret-sharing data. Task two forms a look-up table for the supply and demand curves generated from the transaction data. Task three is to decide the parameters for finding the equilibrium of demand and supply curves. Task four is to generate their graphic and tabular outputs for winners. The experimental bid-opening system for trading eggs has been well tested at various environments. The performance shows the feasibility of the underlying system.
