In the modern digital era, information systems must operate in increasingly interconnected and dynamic environments, which force them to be changeable yet consistent. Such modern information systems are usually decision- and knowledge-intensive. A recently introduced standard, the decision model and notation (DMN), has been adopted in both industry and academia as a suitable method for modelling decisions and decision rules. Noteworthy is that, despite the dynamic nature of modern knowledge-intensive systems, DMN was only studied and implemented in a static fashion, as decision schema change patterns have not received any attention so far. This paper identifies and analyses the change patterns that can occur in a DMN decision model. A change in the decision model can require the triggering of other changes in order to safeguard consistency. As such, this paper will also investigate for each change pattern which further changes should be performed to ensure model consistency. The patterns presented in this paper will not only facilitate the understanding of decision change management and within-model consistency, but can also be capitalised on for developing and implementing flexible decision management systems. To illustrate this, we present a modelling environment prototype that provides modelling support when applying the proposed change patterns.

动态系统演化的决策模型更改模式

在现代数字时代,信息系统必须在日益互连的动态环境中运行,这迫使它们变得多变而又一致。这种现代信息系统通常是决策和知识密集型的。行业和学术界都采用了最近引入的标准,即决策模型和表示法(DMN),作为对决策和决策规则进行建模的合适方法。值得注意的是,尽管现代知识密集型系统具有动态性质,但由于决策模式更改模式到目前为止尚未受到任何关注,因此仅以静态方式研究和实现了DMN。本文确定并分析了DMN决策模型中可能发生的变化模式。决策模型中的更改可能需要触发其他更改,以维护一致性。因此,本文还将针对每种变更模式进行调查,以确保模型的一致性,应进行进一步的变更。本文介绍的模式不仅有助于理解决策变更管理和模型内一致性,而且还可以用于开发和实施灵活的决策管理系统。为了说明这一点,我们提供了一个建模环境原型,该原型在应用建议的变更模式时提供了建模支持。但也可以利用它来开发和实施灵活的决策管理系统。为了说明这一点,我们提供了一个建模环境原型,该原型在应用建议的变更模式时提供了建模支持。但也可以利用它来开发和实施灵活的决策管理系统。为了说明这一点,我们提供了一个建模环境原型,该原型在应用建议的变更模式时提供了建模支持。
