In this paper, we study the coordination issue in a dual-channel green supply chain with one manufacturer and one retailer. The demand in the traditional channel is assumed to be dependent on retail price, sales effort and green degree. Due to the characteristic of live broadcast selling, the demand in the direct channel is assumed to be dependent on price and discount. On the basis of analyzing price, sales effort and green degree strategies in the supply chain under the centralized model, two decentralized models and two coordination models are presented. Moreover, we prove the feasibility of sharing the R&D costs of the green degree and sales effort costs of the advertisement (CS-GS) contract through bargaining problems achieving a win-win situation, but the revenue sharing and wholesale price (RSC) contract commonly used cannot efficiently coordinate the supply chain. Finally, numerical analysis is given to show the impacts of coordination contracts on the supply chain’s performance as well as the impacts of parameters on profits and decisions in the four models. It reveals that the CS-GS contract can not only help to improve the green degree and the price of the product, but also improve the profitability of all supply chain members.

For enhance running effectiveness efficiency of logistics carriage supervisory depended on wireless sensor network (WSN), a novel wireless sensor network optimized by improved bat algorithm is established. Firstly, working theory and system framework of WSN depended on logistics monitoring system are analyzed. Secondly, B-MAC protocol is used in proposed wireless sensor network, and corresponding models are established, and recovery ratio of wireless sensor network is defined, and node deployment optimization of wireless sensor network is constructed. Thirdly, the optimization algorithm of node deployment of WSN is designed based on amended bat algorithm, and analysis procedure of this algorithm is established. Finally, a simulation analysis is carried out, analysis results show that performance of proposed WSN logistics carriage supervisory based on improved bat algorithm is better, which has quicker convergence speed and higher convergence precision, and reliability of proposed WSN logistics carriage supervisory is improved, the energy consumption of sensor node data transmission is reduced, and the life of WSN is improved. Proposed WSN based on logistics carriage supervisory based on improved BA has higher coverage ratio and higher efficiency. Therefore proposed wireless sensor network based on logistics carriage supervisory based on improved bat algorithm can obtain better monitoring efficiency, which has prospect application view.

In the past, the literature often mentioned the relationship of trust and commitment, and believed that the lack of trust among supply chain members would lead to poor performance in transaction costs. Some studies believe that specific assets, behavioral uncertainty, and information sharing in the transaction cost theory have an impact on the trust level of supply chain partners. Other studies have pointed out the satisfaction of transaction partners and the reputation of partners in the market in social exchange theory. The degree and the cognition of both parties to the transaction will also affect the performance of the supply chain. This study attempts to integrate the above two theories and proposes an overall model of the factors affecting trust and commitment, and then uses the structural equation model (SEM) to carry out measurement models, structural models and the overall model is tested, and the research results indicate that the trust level is significantly related to the commitment level, while the manufacturer's investment in specific assets, the uncertainty of both parties' behavior, and the cognition level of both parties in the transaction in the theory of social exchange are all significantly related to the level of trust. Negative correlation; in transaction cost theory, partners' investment in special assets, information sharing, and social exchange theory, satisfaction with trading partners, trading partners' reputation and trust levels are significantly positively correlated, research results can provide supply chain management. As a reference, we will carry out partnership maintenance and management decision-making options.
