| Summary: | 碩士 === 淡江大學 === 資訊管理學系碩士班 === 97 === To improve the practicability of Negotiation Support System, NSS, We developed one WebNSS to offer a computerized supports with two-party and multi-issue negotiation. The system includes four practical support modules: the first is Preference Capture Module, PC; the second is Utility Calculation Module, UC; the third is Strategy Support Module, SS; the last is Negotiation Dance Guiding Module, NG. As for Preference Capture Module and Utility Calculation Module, we designed our system on the basis of the Utility Function [14] and Additive Scoring System [18] to offer three preference settings. As for strategies model, we exploited Faratin`s Strategies Model [9] to provide multi-issue strategies by weighting a group of single-issue strategies for users.
To assess the effectiveness of WebNSS, we hired 42 (21 pairs) negotiators to adopt webNSS for examining its effects. The results are summarized as the following three points: (1) There is substantial improvement by using Simple and usable Utility Calculation Module. The result shows that usability is very important for human negotiators.(2)Automated negotiation-support, such as strategies support, can assist human negotiators in the negotiation processes and this effectively improves the negotiation outcomes.(3)There are significant contributions to improving the effectiveness, fairness and transaction time of the contract by using Negotiation support system. Therefore, Enterprises will be worth being implemented the WebNSS into their business processes.
