    , Article Journal of Supercomputing ; Volume 66, Issue 3 , 2013 , Pages 1350-1389 ; 09208542 (ISSN) Adabi, S ; Movaghar, A ; Rahmani, A. M ; Beigy, H ; Sharif University of Technology
    Providing an efficient resource allocation mechanism is a challenge to computational grid due to large-scale resource sharing and the fact that Grid Resource Owners (GROs) and Grid Resource Consumers (GRCs) may have different goals, policies, and preferences. In a real world market, various economic models exist for setting the price of grid resources, based on supply-and-demand and their value to the consumers. In this paper, we discuss the use of multiagent-based negotiation model for interaction between GROs and GRCs. For realizing this approach, we designed the Market- and Behavior-driven Negotiation Agents (MBDNAs). Negotiation strategies that adopt MBDNAs take into account the...

    A Framework for Price Negotiations in Presence of Alternative Options

    , M.Sc. Thesis Sharif University of Technology Purmehdi, Mostafa (Author) ; Sheikhzadeh, Mehdi (Supervisor)
    The present research investigates the conjunction of two areas of pricing and negotiation techniques to find a relationship between price and other key factors such as quality, quantity, time, etc. and observe the overall effect of these factors on how to design and implement negotiations over price in B2B environment. The research presents a model to describe the process of negotiation and applies quantitative methods to rank negotiable scenarios. This set of scenarios, then is sorted in a triangular model of negotiation strategy and is used as a roadmap for negotiation. Furthermore, researcher evaluates effective tactics and their implementation to drive negotiation sessions based on... 

    Caspian Sea negotiation support system

    , Article World Environmental and Water Resources Congress 2010: Challenges of Change - Proceedings of the World Environmental and Water Resources Congress 2010, 16 May 2010 through 20 May 2010 ; 2010 , Pages 2694-2702 ; 9780784411148 (ISBN) Rouhani, O.

    Caspian Sea is currently a subject of one of the world's most intractable disputes, involving five coastal states of Azerbaijan, Iran, Kazakhstan, Russia, and Turkmenistan. The conflict over the legal status of this multinational water body emerged after the collapse of the Soviet Union. Since then the parties have been negotiating without reaching an agreement on the ownerships of waters, and the oil and natural gas beneath them. Although different division methods have been suggested so far for sharing the Caspian Sea, the gains of the countries from sea area and valuable resources remain unclear as the proposed methods are either focused on the areal shares or on the oil and gas shares.... 

    Optimizing Replenishment and Pricing in a Vendor-managed Inventory Supply Chain When Customers Negotiate

    , M.Sc. Thesis Sharif University of Technology Bagherirad, Sonia (Author) ; Modarres Yazdi, Mohammad (Supervisor)
    In this study vendor-managed inventory policy in supply chains is investigated and a formulation is developed to optimize replenishments from vendor to retailer and also price for negotiator customers. As a result, we consider a two echelon supply chain containing a vendor and a retailer managed according to VMI policy. The goal is to find the optimal replenishment from vendor to retailer at the beginning of the month and by using dynamic programming approach to maximize the supply chain profit. Demand is nondeterministic and it is supposed Poisson distribution with unknown parameter. We will consider Gamma distribution for this parameter which its parameters are learning in dynamic... 

    Dynamic Pricing with Considering Customers Negotiation and Reference Price Effect

    , M.Sc. Thesis Sharif University of Technology Meskar, Mahla (Author) ; Modarres Yazdi, Mohammad (Supervisor)
    This thesis studies optimal pricing policy of a firm selling perishable products in a retail store facing stochastic arrival of customers whom may ask for a bargain. With the tremendous growth of the internet and online sale channels, the ability of customers to get detailed information about previous sales creates an expectation for reasonable price of product in customers' opinion called reference price which has great impacts on their willingness to pay. In this work, we address the problem of determining a pricing strategy considering reference price effects in addition to customers' negotiation ability. We use dynamic programming to model retailer's problem, which considering reference... 

    Market-based grid resource allocation using new negotiation model

    , Article Journal of Network and Computer Applications ; Volume 36, Issue 1 , 2013 , Pages 543-565 ; 10848045 (ISSN) Adabi, S ; Movaghar, A ; Rahmani, A. M ; Beigy, H ; Sharif University of Technology
    This paper presents a new negotiation model for designing Market- and Behavior-driven Negotiation Agents (MBDNAs) that address computational grid resource allocation problem. To determine the amount of concession for each trading cycle, the MBDNAs are guided by six factors: (1) number of negotiator's trading partners, (2) number of negotiator's competitors, (3) negotiator's time preference, (4) flexibility in negotiator's trading partner's proposal, (5) negotiator's proposal deviation from the average of its trading partners proposals, and (6) previous concession behavior of negotiator's trading partner. In our experiments, we compare grid resource consumer (GRC) of type MBDNAs (respectively... 

    Analyzing the Two-Stage Supply Chain with Iso-Elastic Demand

    , M.Sc. Thesis Sharif University of Technology Moeini, Soroush (Author) ; Ghasemi Tari, Farhad (Supervisor)
    In the last two decades, Supply Chain Management has become an integral part of sciences such as Management and Industrial Engineering. A key issue in this concept is how to coordinate the activities of the members of the chain in order to improve the performance of the whole system. In this thesis, the main concentration is on production, pricing and lot-sizing policies in a two-stage supply chain with a producer and a retailer. The producer manufactures the final product and vends it to the retailer, and the retailer sells it to the final customer. The customer’s demand is under iso-Elastic pattern that is one the four most popular price-sensitive demand functions. Moreover, in attempting... 

    Analysis of Factors Affecting IPO Initial Returns of the Tehran Stock Exchange

    , M.Sc. Thesis Sharif University of Technology Kanani Torshizi, Mostafa (Author) ; Talebian, Masoud (Supervisor) ; Ebrahimnejad, Ali (Supervisor)
    In the present study, the factors that affect the IPO underpricing in the Tehran Stock Exchange are investigated. We define the variables of IPO percentage, age and size of companies, dummy variable for rounded IPO prices, market return in a month before the initial public offering, average return of IPOs that had been done during one month before the IPO of each ticker and the dummy variable for industrial group in which the company is located. We had to calculate the initial return of 246 companies that were offered in the years 1380 to 1395. In this study, due to the existence of a daily stock price volatility constraint, a new algorithm was introduced to calculate the dependent... 

    Agent-based web service for the design of a dynamic coordination mechanism in supply networks

    , Article Journal of Intelligent Manufacturing ; Volume 20, Issue 6 , 2009 , Pages 727-749 ; 09565515 (ISSN) Mahdavi, I ; Mohebbi, S ; Zandakbari, M ; Cho, N ; Mahdavi Amiri, N ; Sharif University of Technology
    The theory of network coordination presents an effective approach to improve the business processes within supply networks. The automation of the negotiation process among buyers and suppliers has become an important policy in the transactional networks. This leads to assessing the roles of both quantifiable and non-quantifiable parameters in coordination mechanisms with the aim of achieving higher performance. Here, we develop an e-based supply chain multi-agent model for the design of mass-customized on-line services. The model addresses the bullwhip effect in multi-stage supply chain and also clarifies the evaluation of inventory policies in various supply and demand uncertainties. To...
