    Markdown budgets for retail buyers: help or hindrance?

    , Article Production and Operations Management ; Volume 26, Issue 10 , 2017 , Pages 1875-1892 ; 10591478 (ISSN) Şen, A ; Talebian, M ; Sharif University of Technology
    Abstract
    For many retailers, markdown decisions are taken by retail buyers whose compensation is based on sales revenue so their objective is to maximize it through the season. This implies that the buyers' objectives are not perfectly aligned with the overall profitability the firm. Many retailers set markdown budgets prior to the season to control margin erosion and increase profitability. Markdown budget constrains the buyers on the amount of discounts that they can apply on a given inventory of merchandise and sets a limit on the dollar value of markdowns for the season. While markdown budgets may be useful in preventing excessive discounts, they can have a detrimental effect on the buyers'... 

    Optimizing shipment, ordering and pricing policies in a two-stage supply chain with price-sensitive demand

    , Article Transportation Research Part E: Logistics and Transportation Review ; Volume 45, Issue 4 , 2009 , Pages 564-571 ; 13665545 (ISSN) Sheikh Sajadieh, M ; Akbari Jokar, M. R ; Sharif University of Technology
    Elsevier Ltd  2009
    Abstract
    In this paper we focus on a two-stage supply chain consisting of one vendor and one buyer. We develop an integrated production-inventory-marketing model to determine the relevant profit-maximizing decision variable values. The model proposed is based on the joint total profit of both the vendor and the buyer, and it finds out the optimal ordering, shipment and pricing policies. We are able to ascertain the optimal decision variable values employing an analytical solution procedure. The numerical evidence suggests that it is more beneficial for the buyer and the vendor to cooperate with each other when the demand is more price sensitive. © 2008 Elsevier Ltd.

    Dynamic Pricing Policies in Presence of Strategic Customer Behavior

    , M.Sc. Thesis Sharif University of Technology Mohseni, Mahdi (Author) ; Modarres Yazdi, Mohammad (Supervisor)
    Abstract
    The problem of developing optimal pricing and inventory allocation strategies has been extensively studied over the past two decades. However, most of the literature in this area assumes that customers are myopic price-takers, and do not respond to firm pricing strategically. In this study, we present review on a class of problems that consider a firm selling a finite number of items over a finite time horizon facing stochastic demand and a group of customers who act strategically by timing their purchases. We first review the optimal purchasing policy for the customers, and pricing policy for the firm that is the best response policy to the customer’s strategic behavior. Then we present a... 

    What do one hundred million transactions tell us about demand elasticity of gasoline?

    , Article Empirical Economics ; Volume 62, Issue 6 , 2022 , Pages 2693-2711 ; 03777332 (ISSN) Vesal, M ; Tavakoli, A. H ; Rahmati, M. H ; Sharif University of Technology

    Abstract
    The price elasticity of gasoline demand is a key parameter in evaluation of various policies. However, most of the literature uses aggregate data to identify this elasticity. Temporal and spatial aggregation make such elasticity estimates biased. We employ a unique dataset of all gasoline transactions in Iran during a 4-month period around an unexpected exogenous price change to identify that price elasticity. We also identify a significant withholding behavior by consumers in response to anticipated price changes. The consumers reduce or postpone their purchases when they expect a decrease in prices. Controlling for date fixed effects would eliminate homogeneous withholding responses.... 

    Optimizing a joint economic lot sizing problem with price-sensitive demand

    , Article Scientia Iranica ; Volume 16, Issue 2 E , 2009 , Pages 159-164 ; 10263098 (ISSN) Akbari Jokar, M. R ; Sheikh Sajadieh, M ; Sharif University of Technology
    Abstract
    This paper considers the problem of a vendor-buyer integrated production-inventory model. The vendor manufactures the item at a finite rate and delivers the final goods at a lot-for-lot shipment policy to the buyer. We relax the assumption of uniform demand in the hitherto existing joint economic lot sizing models and analyze the problem where the end customer demand is price-sensitive. The relation between demand and price is considered to be linear. The model proposed, based on the integrated expected total relevant profits of both buyer and vendor, finds out the optimal values of order quantity and mark-up percentage, using an analytical approach. Some numerical examples are also used to... 

    Gender-based Choice Behavior in Central Zone Pricing Policy Condition

    , M.Sc. Thesis Sharif University of Technology Khalili khah, Majid (Author) ; Kermanshah, Mohammad (Supervisor)
    Abstract
    Transportation systems have been impressed the humankind societies in an astonishing way. However, there are some weak points that have been accompanied with them. In order to decrease these effects, some strategies such as Transportation Demand Management (TDM) methods have been proposed in some few literatures. In this study, regarding increasing women’s role in urban trips and also some gender based differences; the effects of pricing have been applied as a management method through a Logit Model. Results show that using dummy gender based values would lead to more reliable consequences rather than some separated models with insufficient information. Moreover, it was concluded that women... 

    Impacts Analysis of Discriminatory Pricing Policies Implementation in the Framework of Iran’s Subsidies Targeting law

    , M.Sc. Thesis Sharif University of Technology Salarkia, Hamed (Author) ; Maleki, Abbas (Supervisor)
    Abstract
    The subsidies targeting law was ratified on October 23, 2009. At mentioned law appointed that the government redistributes up to 50% of earned revenues from price reforming of energy carriers to households by cash and non-cash payments and 30% of earned revenues to the production sector. But reports studies indicate that from 2010 to 2016, the government allocated 93.4% of the revenues to households in cash and non-cash and only 0.7% to the production sector. It can, therefore, be concluded that the subsidies targeting law has not been properly implemented. Indeed, the government has not only failed to fully reform energy carriers prices, but also has increased the households’ share of...

    Abstract
    This article presents a new model for pricing a new product considering a skimming pricing strategy in the presence of competition. We consider two periods for price setting, including skimming and an economy period. The problem is to decide on skimming as well as economy price, in order to maximize total profit. The derived model is a non-linear programming model and we have analyzed the structure and properties of an optimal solution to develop a solution method. Analytical results, as well as managerial insights, are presented by mathematical and numerical analyses

    Abstract
    In recent years there have been many efforts to develop a hydrogen energy system in Iran. For instance, the Iranian fuel cell steering committee conducted a project and determined some targets to implement hydrogen in different sectors, especially transportation. In this paper, the costs of building stations and the levelized cost of hydrogen for two types of stations, SMR and electrolysis, with various sizes and capacity factors have been investigated. Also, in the case of electrolysis, hydrogen cost sensitivity to the price of electricity has been examined. According to the cost analysis conducted here, it is understandable that hydrogen costs ($/kg) vary considerably based on station... 

    A multi-stage stochastic programming model for dynamic pricing and lead time decisions in multi-class make-to-order firm

    , Article Scientia Iranica ; Volume 18, Issue 3 E , 2011 , Pages 711-721 ; 10263098 (ISSN) Chaharsooghi, S. K ; Honarvar, M ; Modarres, M ; Sharif University of Technology
    2011
    Abstract
    Make-to-order firms use different strategies, such as dynamic pricing and due date management, to influence their performance. In these strategies, orders are segmented into classes based on their sensitivity to lead time and price. Quoting different prices and lead times to different classes of customer can increase a firm's profit and its capacity utilization. Most research in this area does not consider the effects of production constraints on price and lead time decisions. In this paper, we consider the role of flexibility in dynamically choosing the price, lead time and segmentation of customers in make-to-order environments with limited production capacity and multi-period horizon...

    Abstract
    Electric spring (ES) as a breakthrough in power electronics has led to a revolution in demand-side management. This paper presents flexible power management (FPM) of a networked microgrid (MG) in the presence of renewable energy sources (RESs) and flexibility sources (FSs). The FSs include the novel topology of the integrated unit of ES with electric vehicles (EVs) parking (IUEE) and incentive-based demand response program (DRP). The proposed FPM model is formulated as an optimization problem that minimizes the difference between the expected energy cost and the expected profit of FSs' flexibility subject to the AC optimal power flow (AC-OPF), RESs, FSs, and MG flexibility constraints. In...
