Selection of Third-party Logistics Provider for Agricultural Products Based on System Comprehensive Evaluation

Through the analysis on the meanings and features as well as the ad- vantages of the third-party logistics for agricultural products, the quantization index system for the selection of third-party logistics providers for agricultural products was constructed based on the system comprehensive evaluation theory. Analytic hierar- chy process （AHP） was used to determine the weight of the index system of each level, and AHP and fuzzy comprehensive evaluation method were used to determine the selection steps for the third-party logistics providers for agricultural products. The method was proved to be scientific and reasonable through calculation examples.

Study on Task Assignment of Two-stage Multi-service Capability Port Logistics Service Providers

This paper mainly studies the problem of multi-task assignment of providers in port logistics service supply chain.As a core enterprise,port plays the role of logistics service integrator.With the continuous development of industrial integration,logistics service providers not only provide one kind of logistics service,but also develop into composite suppliers who capable of providing a variety of logistics services.This paper studies the task assignment problem of multi-service capability providers in the port logistics service supply chain.The two-stage logistics service provider task assignment model was built,which is based on the mixed evaluation method(including MOORA and FMEA)and the multi-objective planning method.Eventually,the effectiveness of the model method was verified by combining with an example.

Hybrid Intelligent Approach for the Selection of Third-Party Reverse Logistics Provider under Uncertainty

A hybrid intelligent approach is proposed to help the decision maker to select the appropriate third-party reverse logistics provider. The following process is included: firstly,the evaluation team is established to determine the selection criteria and evaluate them by triangular fuzzy numbers; secondly,calculate the weight of criteria by the proposed hybrid algorithm integrating particle swarm optimization( PSO) and simulated annealing( SA); then, the performance evaluation for each supplier is predicted by the proposed self-feedback neural network( SFBNN) based on the historical data. A numerical example is also presented to interpret the methodology above.

Survival Analysis of Logistics Service Providers: An Empirical Study of Chengdu, Area in China

This paper worked on a sample of 6791 logistics establishments registered in Chengdu, China over the period 1984-2016 to understand the survival status of logistics service providers (LSPs) by non-parametric Kaplan-Meier estimation, together with Cox proportional hazard regression model, to identify factors affecting the failure of LSPs. In particular, it studies the interaction effect between LSPs’ size and entry timing and location. The empirical results show that: 1) Regarding the survival time, 1365 of the 6791 sample LSPs exited from the market by 2017. The exit rate is 20.1%, and the average life of the 6791 LSPs is about 6 years. 2) The survival of LSPs depends on their typology, ownership structure. And there is no significant difference in the probability of survival for both independent LSPs and logistics branches after controlling the effects of other variables. 3) Location and entry timing also play an important role in the survival of small-scale LSPs, but these factors cannot explain large-scale LSPs’ failure.

Selecting a Strategic Logistics Service Provider for Subsea Engineering Companies on the Tweneboa, Enyenra and Ntomme （TEN） Project in Ghana

The research dealt with assessment of logistics service providers＇ capabilities in SECs （supporting subsea engineering companies） on the Tweneboa, Enyenra and Ntomme （TEN） project in Ghana.

The study concluded Consolidated Shipping Agency （Conship） was the best Logistics Service Provider to offer the best consolidated services for project optimization under the TEN project.

Improving Value Chain Through Efficient Port Logistics

Emerging as a dynamic economy in the South East Asia, Vietnam, the 151 st WTO member has to improve export goods value chain to create sustainable competitive advantage. Nowadays, Vietnam port-logistics sector has been becoming one of the most important service industries that contribute intensively to create value for Vietnam export goods in global market. This paper discusses one of the contemporary challenging issues for Vietnam--how to improve value chain through efficient port logistics. The objective of this research is to review literature issue of value chain, analyse the situation of Vietnam logistics sector, especially in port logistics and provide some recommendations to improve value chain of Vietnam export goods. The surveyed issues of both sides of logistics service providers （LSPs） and beneficial cargo owners （BCOs） will be taken into consideration. Based on the findings result, some actions are suggested to the government and local logistics service providers to make necessary decisions and solutions to improve value chain of Vietnam export goods through efficient port logistics.

Survey of Sustainable Logistics Services via Text Mining

Environmental sustainability has recently become more and more of a concern in logistics service industry. Although studies on sustainable initiatives among logistics service providers (LSP) have been increasing in the extant literature, still little investigation has been performed between LSPs and shippers. The present paper aims to demonstrate award-gained sustainable logistics service initiatives implemented during the period 2006-2017 in Japan. Different with questionnaire- and interview-based studies employed in literature, we use text mining technique to explore the co-occurring links of data, i.e. connections of the practices, to present the collaborative sustainability actions carried out through providing and requiring logistics services. In contrast to the research regarding green supply chain management focused on manufacturing perspective, this study is positioned in the dual sides of consignors and logistics business operators, to depict their combined effort in achieving sustainability goals. The results of the study showed that text mining technique is useful for summarizing and presenting data in this research area. However, much remains to be learned about how to deal with the data more means-end logically for revealing more indirect associations between the data.

LSSC内物流服务集成商管理策略对提供商安全生产行为的影响研究

考虑由“功能型物流服务提供商—物流服务集成商—客户”构成的物流服务供应链(Logistics Service Supply Chain, LSSC),针对链内提供商安全生产问题的动态性与复杂性,探究集成商不同管理策略对提供商安全生产行为的影响。采用计算实验方法,抽象模拟出二者在选择与合作阶段的交互活动,分别进行集成商订单配置决策中安全因素权重、安全生产考评标准、安全风险抵押金对提供商安全生产行为的影响实验。研究结果表明:在客户具有安全偏好情况下,集成商通过合理的订单配置决策可实现提供商安全生产水平与自身收益的协同提升;当安全生产考评标准超过提供商可接受阈值时,其安全生产水平反而将会降低;收取安全风险抵押金可使提供商安全生产水平有所提高,但效果有限。

Towards Developing Privacy-Preserved Data Security Approach(PP-DSA)in Cloud Computing Environment

In the present scenario of rapid growth in cloud computing models,several companies and users started to share their data on cloud servers.However,when the model is not completely trusted,the data owners face several security-related problems,such as user privacy breaches,data disclosure,data corruption,and so on,during the process of data outsourcing.For addressing and handling the security-related issues on Cloud,several models were proposed.With that concern,this paper develops a Privacy-Preserved Data Security Approach(PP-DSA)to provide the data security and data integrity for the out-sourcing data in Cloud Environment.Privacy preservation is ensured in this work with the Efficient Authentication Technique(EAT)using the Group Signature method that is applied with Third-Party Auditor(TPA).The role of the auditor is to secure the data and guarantee shared data integrity.Additionally,the Cloud Service Provider(CSP)and Data User(DU)can also be the attackers that are to be handled with the EAT.Here,the major objective of the work is to enhance cloud security and thereby,increase Quality of Service(QoS).The results are evaluated based on the model effectiveness,security,and reliability and show that the proposed model provides better results than existing works.
