most of data in multi-attribute decision making (madm) problems are changeable rather than constant and stable. therefore, sensitivity analysis after problem solving can effectively contribute to making accurate decisions. in this paper, we offer a new method for sensitivity analysis in multi-attribute decision making problems in which if the weights of one attribute changes, then we can deter...

Today’s supply chains require more dynamic trading practices to better match suppliers with their customers. Additionally, the purchase decisions faced are rarely made on price alone; but rather on a bundle of attribute values. With ubiquitous computing and Internet connectivity, newer types of negotiation are emerging such as reverse auctions. This paper presents a heuristic algorithm for mult...

Social concerns about the environment and global warming suggest that industries must focus on reducing energy consumption, due to its social impact and changing laws. Furthermore, the smart grid will bring time-dependent tariffs that pose new challenges to the optimisation of resource allocation. In this paper we address the problem of optimising energy consumption in manufacturing processes b...

This study contrasts the call and continuous auction methods using Taiwan Stock Exchange data. Volatility under the call market method is approximately one-half of that under the continuous auction method. The call market method is more effective in reducing the volatility of high-volume stocks than low-volume stocks. This contradicts conventional wisdom which suggests that the call market meth...

There are many different ways to allocate resources in cloud computing. The economic methods are some of common ways to resource allocation. The auction-based method has some advantages compared with Fixed-Price method. The double combinatorial auction is one of the proper ways of resource allocation in cloud computing. Resource allocation in double combinatorial auction includes two phases. Th...

This paper first describes a few existing models for product and merchant brokering and automated negotiation in the framework of agent-based e-marketplaces. Our analysis shows that only simplest types of automated negotiation protocols are currently presented online, whereas some powerful systems have been already implemented in the product and merchant brokering field. Then we give an overvie...

In this paper we consider the problem of designing a mechanism for double auctions where bidders each bid to buy or sell one unit of a single commodity. We assume that each bidder’s utility value for the item is private to them and we focus on truthful mechanisms, ones where the bidders’ optimal strategy is to bid their true utility. The profit of the auctioneer is the difference between the to...

Cloud computing has been an emerging model which aims at allowing customers to utilize computing resources hosted by Cloud Service Providers (CSPs). More and more consumers rely on CSPs to supply computing and storage service on the one hand, and CSPs try to attract consumers on favorable terms on the other. In such competitive cloud computing markets, pricing policies are critical to market ef...
