Stagnation of the negotiation-based cloud market refers to a condition of having negligible or no successful (good) deals. Cloud market stagnation should be reduced as it has a detrimental effect on the market outcomes. One of the effective steps towards overcoming market stagnation is by focusing on temporary replacing the pricing mechanism with the more effective ones. To do this, we propose a new agent-based hybrid marketplace in which the elements of the negotiation market are combined with the elements of auction as another well-known market-driven pricing mechanism. That is, negotiation market is considered as the main basis of the proposed hybrid market where each resource provider can make decisions about holding ad-hoc auction(s) when experiencing high market pressure to exit the market stagnation and create dynamism in the market. Thus, in this paper, issues and challenges related to when and how an auction should be held are answered. Extensive amounts of simulation were carried out to evaluate the performance of dealer agents who deal in the proposed hybrid market in comparison with MBDNAs known as (Market-and-Behavior-Driven Negotiation Agents) in terms of average utility, success rate, and the time needed to reach an agreement. The results show that our designed dealer agents outperform MBDNAs.

用于云资源分配的新多代理混合市场

基于谈判的云市场的停滞是指几乎没有或没有成功（好的）交易的情况。应减少云市场停滞，因为它对市场结果产生不利影响。克服市场停滞的有效步骤之一是专注于用更有效的定价机制临时取代定价机制。为此，我们提出了一个新的基于代理的混合市场，其中谈判市场的元素与拍卖的元素相结合，作为另一种众所周知的市场驱动定价机制。也就是说，谈判市场被认为是拟议混合市场的主要基础，每个资源提供者可以在遇到高市场压力时做出关于举行临时拍卖的决定，以退出市场停滞并在市场中创造活力。因此，在本文中，将回答与何时以及如何举行拍卖有关的问题和挑战。进行了大量模拟，以评估在拟议混合市场中交易的经销商代理在平均效用、成功率和时间方面与 MBDNA 相比（市场和行为驱动的谈判代理）的表现需要达成协议。结果表明，我们设计的经销商代理的表现优于 MBDNA。以及达成协议所需的时间。结果表明，我们设计的经销商代理的表现优于 MBDNA。以及达成协议所需的时间。结果表明，我们设计的经销商代理的表现优于 MBDNA。
