基于internet的服务供应面临的挑战之一是为最终用户提供一种质量控制措施。实现这一点的一种方法是采用某种形式的合同协议，例如在客户（最终用户）和服务提供者之间采用服务水平协议。我们认为，这种协议具有内在的不确定性，其形式是客户对协议的遵守的信念状态。本文主要关注三个方面。首先，我们讨论了服务提供中的不确定性问题，随后引入了不确定性容忍度的概念。其次，我们讨论了提供对不确定性容忍度的方法，其中涉及贝叶斯和决策网络的应用。最后，我们提出了一个案例研究来说明问题和我们的解决方案，随后进行实证评估，以表明我们的解决方案是有效的。
One of the challenges for Internet-based service provisioning is to provide a measure of quality control to the end users. One way to enable this is by having a form of contractual agreement such as employing Service Level Agreement between the customer (end user) and service provider. We argue that such agreement has inherent uncertainty in the form of customer’s state of belief towards the compliance of the agreement. This paper focuses on three main areas. Firstly, we discuss the problem of uncertainty within service provisioning offer and subsequently introduce the concept of uncertainty tolerance. Secondly, we discuss our approach of providing a measure of tolerance towards uncertainty which involves the application of Bayesian and Decision Networks. Finally, we present a case study to illustrate the problem and our solution, followed by an empirical evaluation to show that our solution works.
