1 Shared warehouse as an inter-supply chain cooperation strategy to reduce the time-dependent deterioration costs
انبار مشترک به عنوان یک استراتژی همکاری بین زنجیره تامین برای کاهش هزینه های زوال وابسته به زمان-2021
Deterioration is one of the main concerns of many food and drug products. To reduce the effects of this phenomenon, various strategies have been proposed so far. In this paper, the collaboration of distributors in two different supply chains using a shared warehouse and its impacts on the deterioration of products which is time- dependent are investigated. Moreover, innovative algorithms are proposed to extract the solution of the models in the non-integrated and integrated supply chains. Next, the cooperative game theory is used to share the benefits of the cooperation between distributors. The numerical results of the paper indicate the efficiency of the proposed strategy in reducing the cost and deterioration of the supply chains. Furthermore, to demonstrate the efficiency of the proposed model in different real-world problems, four possible categories of the deterioration rate are scrutinized. The results of this investigation denote that the strategy has high effectiveness in all categories while in the category that the deterioration rate is a linear function of the time, the saving in the deterioration cost using the strategy is greatest. Also, conducting a sensitivity analysis, it is revealed that the greater the difference in the ordering cost of distributors, the greater the effectiveness of the strategy in reducing supply chain costs.

2 Negotiation-sequence, pricing, and ordering decisions in a three-echelon supply chain: A coopetitive-game analysis
توالی مذاکره ، قیمت گذاری و تصمیمات سفارش در یک زنجیره تأمین سه پله ای: تجزیه و تحلیل بازی مشارکتی-2021
We investigate a three-echelon supply chain in which a distributor at the middle echelon negotiates two wholesale price contracts with his upstream manufacturer and downstream retailer. In the first stage, the distributor decides on whether to first negotiate with the manufacturer or with the retailer; in the second (combined, noncooperative-cooperative, game) stage, the two negotiations are conducted sequentially. We find that the supply chain can be coordinated if the distributor first negotiates with the retailer. The distributor should choose the negotiation sequence for supply chain coordination, if he has a sufficiently large (small) relative bargaining power in the negotiation with the manufacturer (the retailer). We also extend our analysis to the cases in which the distributor and the manufacturer negotiate a buyback or two-part tariff contract, and draw similar outcomes when the distributor first negotiates with the retailer. In addition, under the two-part tariff contract, the distributor prefers to first negotiate with the retailer if the manufacturer has a sufficiently high disagreement payoff whereas, under the buyback contract, the distributor always prefers to first negotiate with the firm with a stronger bargaining power. Moreover, the two-part tariff (buyback) contract cannot (can) always coordinate the supply chain.

3 Willingness-to-cede behaviour in sustainable supply chain coordination
رفتار تمایل به ترک در هماهنگی پایدار زنجیره تأمین-2021
: Willingness-to-cede (WTC) profit behaviours for the purpose of effective cooperation have increasingly emerged as a best practice in competitive supply chain environments; however, this has been complicated by sustainability issues. Inspired by this fact, we study normative prescriptions and models that can be used to coordinate sustainable supply chains considering supply chain leaders’ WTC behaviour. Along this line, we adopt a multi-methodological approach and carry out a two-stage analysis of a three-player duopoly supply chain (SDSC) with a leader (i.e., the focal firm) and two competitive followers who provide sustainable products or services. In the first stage, we adopt a non-cooperative game to characterize the interactions within five non-cooperative and cooperative models. In the second stage, to coordinate the SDSC, we first derive the characteristic functions from the equilibrium results of the five models and then revise the classical equal allocation of the non-separable contribution (EANSC) value by incorporating the leader’s WTC behavioural parameter. This revised EANSC value serves as a novel solution and thereby enhances the scientific value of the cooperative game theoretical approach. Analytical and numerical studies show that under conditions in which the leader has power and is willing to cede, the optimal coordinated solutions can be obtained when both sustainability competition and the WTC are at a low level; leaders are not willing to cede profits if sustainability competition is high due to product substitutability between two followers. This research illustrates how behavioural theory and non-cooperative and cooperative game theory can be sufficiently modified and adopted to advance supply chain-level cooperation for sustainability. We further carry out a survey and interviews to provide empirical evidence to support our findings.

4 An intelligent scheduling scheme for real-time traffic management using Cooperative Game Theory and AHP-TOPSIS methods for next generation telecommunication networks
برنامه زمان بندی هوشمند برای مدیریت ترافیک در زمان واقعی با استفاده از نظریه بازی تعاونی و روش AHP-TOPSIS برای نسل بعدی شبکه های مخابراتی-2017
The emerging and exponential growth of telecommunication networks have developed a variety of smart and powerful devices to handle a wide range of multimedia applications such as Voice over IP (VoIP), video streaming, etc. 3GPP introduced Long Term Evolution (LTE) in release 8 and LTE-Advanced (A) in release 10 to support multimedia traffic as these technologies offers high data rate, high bandwidth, and low latency. It also created new challenges to handle resource allocation and power optimization of User Equipment (UE). The paper explores radio resource allocation and power consumption problem of UE in LTE environment. An intelligent scheduling scheme developed is based on Cooperative Game Theory (CGT) method and AHP-TOPSIS method. It distributes resources in a fair way among a number of applica tions and UE are prioritized based on certain criteria like delay, throughput history, UE buffer space and channel conditions and preferences. In LTE, Discontinuous Reception (DRX) has been adopted to conserve the battery life of UE. DRX periodically switches off the radio interfaces to conserve the battery life but it may breach Quality of Service (QoS). Therefore, the DRX parameters need to be further optimized to sat isfy QoS and minimize power consumption of UE. DRX parameters are dynamically adjusted on the basis of current load and channel condition of the network. Power saving operations are numerically analyzed. Simulation results show that the expert and an intelligent system can distribute resources in a fair way among UE, improves the battery consumption of UE up to 85% and packets transmission delay by 10% as compared to existing scheme for real-time applications.
