It takes account of demand uncertainty and multiple cost factors, such as transportation cost, time cost, waiting cost before consolidation, penalty cost of not full load after distribution, track changing cost, and customs clearance fee. A complicated mixed-integer programming (MIP) model is presented to describe the problem. Then a solution method based on binary particle swarm optimization (BPSO) is designed to solve the model of different scales of cases. Extensive numerical experiments generated from real-world data are conducted to validate the effectiveness of the proposed model. Moreover, we compare the efficiency of the solution method with a commercial solver and a heuristic algorithm based on variable neighborhood search (VNS). Results show that our solution method can optimally solve the problem in small-scale cases and get near-optimal solutions for large-scale problem instances. The proposed mathematical model and the calculation results may provide valuable insights for both business owners and government.","PeriodicalId":8478,"journal":{"name":"Asia Pac. J. Oper.

To ensure the effective operation of the supply chain and to solve problems such as asymmetric information, difficult data quality assurance, and uncontrollable transportation in shipping logistics services, blockchain technology are proposed to reduce information interaction problems. In view of the factors of information sharing and customers’ sensitivity to information quality, a tripartite evolutionary game model with the shipping company, the port and the freight forwarder as the research objects was established, and the cooperative decision making of node companies was discussed before and after the application of blockchain technology. Theoretical derivation and data analysis show that ports and freight forwarder in the supply chain of shipping logistics services dominated by shipping companies are less affected by information sharing and customers’ sensitivity to information quality. With the increase in the application of blockchain technology, when customers have lower expectations for information quality, shipping companies are more willing to cooperate actively. The willingness to cooperate actively between ports and shipping companies is increasing faster than when blockchain technology is not used. Therefore, shipping companies should encourage the active use of blockchain technology to reduce the degree of information sharing between ports and freight forwarder and the influences of customer expectations on shipping companies.","PeriodicalId":8478,"journal":{"name":"Asia Pac.

This study establishes the ZSG-DDF model combining the Zero-Sum Gains DEA and the Directional Distance Function to study the CO2 emission allowance allocations from the perspective of maximum efficiency. This model can discriminate desirable and undesirable outputs and solve the problem of total CO2 emission amount control. Then, we add the equity principle to the constraint conditions, namely, the proportion of carbon emission allowance approaching the proportion of GDP. Finally, we establish a CO2 emission allocation scheme based on the equity-efficiency tradeoff while considering the relationship between economic development and carbon emissions as well as achieving maximum efficiency. We use this new model to allocate CO2 emission allowance during the Chinese 13th Five-Year Plan, and compare it with the other two allocation schemes, including National allocations during the 13th Five-Year Plan, allocation scheme from the perspective of efficiency maximization. The results have a certain significance for government departments to formulate the allocation scheme of CO2 emission allowance.","PeriodicalId":8478,"journal":{"name":"Asia Pac. J. Oper.

The application of blockchain technology with anti-counterfeiting and traceability can improve the reliability and authenticity of product information and eliminate consumer doubts about product quality. Furthermore, based on the transparency of blockchain technology, brand suppliers can independently obtain the market demand information through information sharing. This paper introduces a consumer suspicion coefficient to illustrate the application of blockchain technology in the supply chain. Considering product authenticity verification and information sharing, we study the optimal pricing and product quality decisions in a two-level supply chain under the following three scenarios: (1) no blockchain technology, a traditional supply chain, and no information sharing (case TN); (2) no blockchain technology but a traditional supply chain with information sharing (case TS); and (3) a supply chain based on blockchain technology (case BT). We find that when the consumer suspicion coefficient increases, consumers will have limited faith in the authenticity of the product, which will affect the retailer’s optimal decision and profit. By comparing the equilibrium results of several cases, we also find that demand information sharing by the retailer may not achieve a win-win outcome in a decentralized channel in the absence of blockchain technology. Under demand information sharing based on blockchain technology, however, if the consumer suspicion coefficient exceeds a certain threshold, the brand supplier and retailer can achieve a win–win outcome. In addition, the extended models reveal that in a centralized supply chain, regardless of the state of market demand, blockchain technology can always improve product quality and retail price and optimize supply chain profit.","PeriodicalId":8478,"journal":{"name":"Asia Pac.
