This paper considers the problem of one buyer procuring multi-items from multiple potential suppliers in electronic reverse auction, where each supplier can bid on combinations items. From perspective buyer, by considering multi-attributes item, a winner determination (WDP) single-unit combinatorial auctions was described and bi-objective programming model established. According to characteristics model, an equivalent single-objective obtained. As is NP-hard, improved ant colony (IAC)...

Nowadays, goods are no longer necessarily traded at a fixed price, and instead buyers sellers negotiate among themselves to reach deal that maximizes the payoffs of both parties. Genetic-agent-based automated negotiation system has become increasingly important since advent electronic commerce rapid development agent technology Genetic Algorithm (GA). In this paper, performance features working principle Agent GA analyzed summarized; genetic-agent-based model can efficiently carry out...

The free-riding behavior of companies that do not act will bring losses to provide services. A market consists two secondary supply chains: manufacturers and retailers. Each chain can choose adopt promotional strategies expand its demand. This paper constructs the centralized decision-making in Nash game competition model between chains primarily studies impact risk aversion coefficient on pricing, promotion strategy selection, expected utility. We show with high-risk has relatively low but...

Purpose This paper mainly focuses on how to induce all members represent members' true preferences for supply and demand matching of E-commerce platform in order generate stable schemes with more social welfare Multi-agent Matching Platform (MMP) individually advantages than traditional methods. Design/methodology/approach An MMP is designed. Meanwhile, a preference inducing method, Lower-Bid Ranking (LBR), proposed reduce the number false preferences, which helpful solve problem that too...

Upstream and downstream of supply chain enterprises often form a tactic vertical alliance to enhance their operational efficiency maintain competitive edges in the market. Hence, it is critical for an collaborate over internal resources resolve profit conflicts among members, so that functionality required by stakeholders can be fulfilled. As effective solution, automated negotiation allied team stakeholder will sufficiently make use emerging advantages significantly reduce teams with...

This paper presents a WDP with supply curve to help the buyer determine winners and assign optimum quantities them while multiattributes of capacity-constrained suppliers are considered in reverse auction setting. A key challenge faced by is that unqualified may cause dire losses NP-hard. combines qualification process for first time relieve potential from buyer's aspect. Based on this idea, two stage mechanism proposed. In stage, Fuzzy Technique Order Preference Similarity Ideal Solution...

In the research of auto-negotiation system, how to enhance ability negotiation parties offer decision-making, improve capability system in process reasoning and decision-making support, always is key success rate efficiency negotiation. According characteristics combining Hidden Markov Model (HMM) with agent technology, making full use superiority HMM dynamic simulation forecasting, this paper proposes a Multi-issue Auto-negotiation System based on (MAS-HMM), which has stronger environmental...

With the relations between coal supply and demand increasingly strained, negotiation has become first choice for resolving contradictions conflicts enterprises coal-fired power plants. The problem of how to improve efficiency promote cooperation agreement widely attracted many scholars' attention. In order simplify process by avoiding establishing complex quantitative analysis results mapping model, this paper constructs auto-negotiation model plants based on Fuzzy Qualitative SIMulation...

he smarter energy industry will become an important economic growth point, Digital procurement of projects is essential link in the development industry, and it necessary to realize supervision enterprise bidding environment through operating digital platform. Based on relationship between similarity quotations collusion behavior enterprises, this paper proposes analysis reasoning model based Hidden Markov Model (HMM). The trained using historical data from enhance judgment capabilities...

The surround-bidding and forging-bidding in Sunshine Procurement is a complicated hidden illegal behavior, which seriously destroys the principle of fairness justice bidding process. In this paper, price taken as research perspective to build an early warning analysis model behavior enterprises based on Clique-Grey Relation Analysis(C-GRA). It uses community discovery identify structure enterprises, at same time, it grey relation mine strong association between enterprise quotations,...
