AbstractDouble auctions are considered to be effective price-scheduling mechanisms to resolve cloud resource allocation and service pricing problems. Most of the classical double auction models use price-based mechanisms in which determination of the winner is based on the prices offered by the agents in the market. In cloud ecosystems, the services offered by cloud service providers are inherently time-constrained and if they are not sold, the allocated resources for the unsold services are wasted. Furthermore, cloud service users have time constraints to complete their tasks, otherwise, they would not need to request these services. These features, perishability and time-criticality, have not received much attention in most classical double auction models. In this paper, we propose a cloud priority-based dynamic online double auction mechanism (PB-DODAM), which is aligned with the dynamic nature of cloud supply and demand and the agents’ time constraints. In PB-DODAM, a heuristic algorithm which prioritizes the agents’ asks and bids based on their overall condition and time constraints for resource allocation and price-scheduling mechanisms is proposed. The proposed mechanism drastically increases resource allocation and traders’ profits in both low-risk and high-risk market conditions by raising the matching rate. Moreover, the proposed mechanism calculates the precise defer time to wait for any urgent or high-priority request without sacrificing the achieved performance in resource allocation and traders’ profits. Based on experimental results in different scenarios, the proposed mechanism outperforms the classical price-based online double auctions in terms of resource allocation efficiency and traders’ profits while fulfilling the double auction’s truthfulness pillar.

In microeconomics, forces of supply and demand lead to stable competition as well as business cycles. Continuous systems with price and quantity adjustments and a cost of labor exhibit Hopf bifurcation and a bifurcation cascade to chaos. Discrete cobweb models capture delayed adjustments that also can exhibit bifurcation cascades. In macroeconomics, investment-savings and liquidity-money capture dynamics in real income related to interest rates. Inflation and unemployment are also coupled through the Phillips curve with adaptive expectations. The stochastic dynamics of the stock market is introduced through stochastic variables that can be added to continuous-time price models. An important example of a stochastic dynamics in econophysics is the Black–Scholes equation for options pricing.
