摘要：
This paper proposes a quantum game to study the food loss and waste (FLW) reduction in a two-echelon food supply chain (FSC) consisting of single supplier and single retailer. First, a Non-zero-sum game model based on the efforts of supplier and retailer in the process of FLW reduction is developed. Then, the classic strategy space is extended to quantum strategy space. The results show that in both classical environment and the separable quantum game scenario, it is difficult to achieve the Pareto optimal strategy of the two parties adopting the full effort strategy, because the full-effort party will bear the risk of betrayal by the non-effort party. However, in the context of maximally entangled quantum game, the risk causing by the non-effort party are borne by himself rather than the full-effort party. Correspondingly, both parties will adopt the full effort strategy to achieve a win-win situation and improve FLW in FSC significantly. Furthermore, an entanglement contract is proposed to ensure that neither of them has the motivation to deviate from the quantum strategy. Based on these findings, some managerial implications are presented to improve the level of cooperation and effort of the supplier and the retailer on FLW reduction. (C) 2020 Elsevier Ltd.

摘要：
Cybersecurity presents a monumental challenge for interconnected supply chains, as an attack on one node can compromise an entire business. In this paper, we propose a game theory model to investigate cybersecurity investments with third-party risk propagation in a two-echelon supply chain consisting of one retailer and n suppliers. The optimal investments and their responses to relevant security characteristics, such as intrinsic vulnerability, propagation probability, number of suppliers, and attack probability, are analysed and discussed both theoretically and numerically considering one-stage risk propagation. It is found that there are serious prisoners' dilemma and free-riding phenomena in such a scenario. To mitigate third-party risks and improve the investment efficiency, three coordination mechanisms, joint decision, security risk compensation, and security information sharing, are presented and compared numerically. The results indicate that joint decision-making and security risk compensation perform better on stimulating firms' investments and reducing expected costs both individually and collectively relative to security information sharing. Furthermore, the case of two-stage risk propagation is also supplemented and compared with one-stage case. Based on these findings, some management insights are recommended to cybersecurity managers in supply chains for designing more efficient cybersecurity mechanisms and investment strategies.
摘要：
This paper considers a supply chain consisting of one supplier and one retailer who jointly invest in item-level radio frequency identification (RFID) by considering their demands and inventories. Since the supplier can be negative to adopt RFID, the main objective of this study is to design an effective mechanism that maximizes the profits of both players and the whole supply chain by implementing item-level RFID. For this objective, we propose a novel revenue-cost-sharing (RCS) contract based on the bargaining game as the incentive to encourage the implementation, and numerical results show that the RCS contract is considerably more effective than the wholesale-price contract for supply chain coordination. Moreover, we show that the retail supply chain can be coordinated perfectly under the RCS contract when the thresholds of the revenue/cost sharing rates are set appropriately. This study provides significant managerial insight into the incentive and coordination strategy to implement item-level RFID in the retail supply chain.

摘要：
In situations where an organization has limited human resources and a lack of multi-skilled employees, organizations pay more and more attention to cost control and personnel arrangements. Based on the consideration of the service personnel scheduling as well as the routing arrangement, service personnel of different skills were divided into different types according to their multiple skills. A mathematical programming model was developed to reduce the actual cost of organization. Then, a hybrid meta heuristic that combines a tabu search algorithm with a simulated annealing was designed to solve the problem. This meta heuristic employs several neighborhood search operators and integrates the advantages of both the tabu search algorithm and the simulated annealing algorithm. Finally, the stability and validity of the algorithm were validated by the tests of several kinds of examples.

摘要：
Third-party logistics (3PL) is a fast growing business. Many large organisations are using 3PL services to reduce operating costs, simplify business processes, and enhance operations and supply chain flexibility. In this paper, we study location-inventory decisions jointly in a closed-loop system with 3PL. First, a model formulation is proposed to develop mixed-integer non-linear programming (MINLP) models for the location-inventory problem under study. Then, a novel heuristics based on differential evolution and the genetic algorithm is designed to solve the MINLP models efficiently. Last, numerical study is presented to illustrate and validate the solution approach.

摘要：
Representation-based classification and recognition, such as face recognition, have dominant performance in dealing with high-dimension data. However, for low-dimension data the classification results are not satisfying. This paper proposes a classification method based on nearest neighbor representation in feature space, which extends representation-based classification to nonlinear feature space, and also remedies its drawback in low-dimension data processing. First of all, the proposed method projects the data into a high-dimension space through a kernel function. Then, the test sample is represented by the linear combination of all training samples and the corresponding coefficients of each training sample will be obtained. Finally, the test sample is assigned to the class of the training sample with a minimum distance. The results of experiments on standard two-class datasets and ORL and YALE face databases show that the algorithm has better classification performance.
