Distributed Electronic Trade Scenarios: Representation, Design, Prototyping
提出电子贸易场景概念，用于支持无先验关系的交易方进行开放电子商务，用文档Petri网表示场景，并开发了InterProcs原型环境辅助设计与执行。
:This paper introduces the concept of the electronic trade scenario as a potential solution to “open” electronic commerce-trade among parties that have no prior trading relationship. The basic idea is that trade scenarios would be stored in a publicly accessible electronic library (perhaps a “global repository” maintained by an independent international organization), and downloaded by trading parties as needed for a particular trade. The documentary Petri net (DPN) is presented as a possible representation for such trade scenarios. The InterProcs system is described as a prototyping environment to support the design and execution of such trading systems using the DPN representation. Given the assumption that the parties are trading at “arm’s length,” a key concern will be the development of trustworthy trade scenarios with sufficient controls and evidentiary documentation. Directions for further work to improve the quality and flexibility of trade scenario designs are described.
