    This paper discusses how a manufacturer and its retailers interact with each other to optimize their product marketing strategies, platform product configuration and inventory policies in a VMI (Vendor Managed Inventory) supply chain. The manufacturer procures raw materials from multiple suppliers to produce a family of products sold to multiple retailers. Multiple types of products are substitutable each other to end customers. The manufacturer makes its decision on raw materials’ procurement, platform product configuration, product replenishment policies to retailers with VMI, price discount rate, and advertising investment to maximize its profit. Retailers in turn consider the optimal local advertising and retail price to maximize their profits. This problem is modeled as a dual simultaneous non-cooperative game (as a Nash game) model with two sub-games. One is between the retailers serving in competing retail markets and the other is between the manufacturer and the retailers. This paper combines analytical, iterative and GA (genetic algorithm) methods to develop a game solution algorithm to find the Nash equilibrium. A numerical example is conducted to test the proposed model and algorithm, and gain managerial implications.supply chain management;nash game model;vendor managed inventory

    Manufacturer's pricing strategies in cooperative and non-cooperative advertising supply chain under retail competition

    Get PDF
    This article studies the manufacturer's pricing strategy in a supply chain with a single manufacturer and two competing retailers. The manufacturer, as a Stackelberg leader specifies wholesale prices to two retailers who face advertisement dependent demand. Based on this gaming structure, two mathematical models are developed - the cooperative advertising model where manufacturer shares a fraction of retailers' advertising costs and the non-cooperative advertising model where manufacturer does not share any retailer's advertising expenses. The optimal strategies of the manufacturer and retailers are determined and a numerical example is taken to illustrate the theoretical results derived. We show that cooperative advertising policy is beneficial not only for the participating entities but also for the entire supply chain

    Research on Cooperative Advertising Decisions in Dual-Channel Supply Chain Under Asymmetric Demand Information When Online Channel Implements Discount Promotion

    Get PDF
    This paper analyzes the both online-channel price discount and advertising decisions in a dual-channel supply chain involved one manufacturer and one retailer. A Stackelberg game dominated by the manufacturer is established. The influence of asymmetric demand information is analyzed. The study shows that retailer has a motivation to lie about the offline demand information and it always announces a higher advertising impact factor. To induce the retailer to reveal to true demand information, a franchise-fee contract is designed

    Vertical Restraints Facilitating Horizontal Collusion: ‘Stretching’ Agreements in a Comparative Approach

    Get PDF
    This article discusses the approaches of the European Union (EU) and of the United States (US) to the notions of agreement and concerted practice applied to horizontal collusive consequences of vertical restraints. It concludes that networks of vertical restraints blur the differences between vertical and horizontal agreements; therefore, both options of attack are available for enforcers in the EU and the US context. If the analysed vertical restraints are adopted in parallel by agreement, they should be deemed illegal as long as they restrict competition producing collusive consequences. In the absence of explicit coordination to adopt the practice, I suggest first looking for a stretched concept of horizontal agreement or a broadly interpreted concept of concerted practice, including unilateral ‘communication’ that intentionally reduces uncertainty. Even when the analysed practices are adopted individually and not by all firms, they can represent a commitment to focal points, observable by market players, thus amounting to communication of intent. If that is not possible, I propose that an analysis of market power, incentives, coercion and induction should guide the finding of an illegal vertical agreement and ground the analysis of the consequences. The agreement/concerted practice path is an appropriate, feasible and coherent way to deal with vertical restraints facilitating horizontal tacit coordination, but that does not exclude alternative effective enforcement mechanisms

    Leader-follower Game in VMI System with Limited Production Capacity Considering Wholesale and Retail Prices

    Get PDF
    VMI (Vendor Managed Inventory) is a widely used cooperative inventory policy in supply chains in which each enterprise has its autonomy in pricing. This paper discusses a leader-follower Stackelberg game in a VMI supply chain where the manufacturer, as a leader, produces a single product with a limited production capacity and delivers it at a wholesale price to multiple different retailers, as the followers, who then sell the product in dispersed and independent markets at retail prices. An algorithm is then developed to determine the equilibrium of the Stackelberg game. Finally, a numerical study is conducted to understand the influence of the Stackelberg equilibrium and market related parameters on the profits of the manufacturer and its retailers. Through the numerical example, our research demonstrates that: (a) the market related parameters have significant influence on the manufacturer’ and its retailers’ profits; (b) a retailer’s profit may not be necessarily lowered when it is charged with a higher inventory cost by the manufacturer; (c) the equilibrium of the Stackelberg equilibrium benefits the manufacturer.Stackelberg Game;Supply Chain;Vendor Managed Inventory

    Designing a clothing supply chain network considering pricing and demand sensitivity to discounts and advertisement

    Get PDF
    none3These days, clothing companies are becoming more and more developed around the world. Due to the rapid development of these companies, designing an efficient clothing supply chain network can be highly beneficial, especially with the remarkable increase in demand and uncertainties in both supply and demand. In this study, a bi-objective stochastic mixed-integer linear programming model is proposed for designing the supply chain of the clothing industry. The first objective function maximizes total profit and the second one minimizes downside risk. In the presented network, the initial demand and price are uncertain and are incorporated into the model through a set of scenarios. To solve the bi-objective model, weighted normalized goal programming is applied. Besides, a real case study for the clothing industry in Iran is proposed to validate the presented model and developed method. The obtained results showed the validity and efficiency of the current study. Also, sensitivity analyses are conducted to evaluate the effect of several important parameters, such as discount and advertisement, on the supply chain. The results indicate that considering the optimal amount for discount parameter can conceivably enhance total profit by about 20% compared to the time without this discount scheme. When the optimized parameter is taken into account for advertisement, 12% is obtained as total profit.openPaydar M.M.; Olfati M.; Triki C.Paydar, M. M.; Olfati, M.; Triki, C
