Due to the rapid development of manufacturing and information technology, traditional supply chain scheme has been changed dramatically Most companies have been forced to relocate or redesign their logistics network in different countries. A supply chain partnership is a relationship formed between two independent members in supply chain through information sharing to achieve specific objectives and benefits in terms of reductions in total costs and inventories. This study illustrates the benefits of supply chain partnerships based on information sharing and lead-time patterns. We consider three level of information sharing: (1) immediate order information; (2) demand information; (3) inventory information. Given a fixed total lead-time, how lead-time distribution will affect the bullwhip effect and inventory cost under information sharing strategies. The results can help improving supply chain performance and selecting suitable direction for the re-configuration of supply chain network.

Purpose: As Thailand endeavors to solidify its position in the global supply chain, unraveling the determinants of innovation and performance becomes imperative for sustained competitiveness. This research delves into the multifaceted landscape of logistics and supply chain organizations in Thailand, aiming to identify and understand the key factors that significantly influence innovation and organizational performance in this dynamic sector. Research design, data, and methodology: A questionnaire is developed to survey to 400 employees who have at least one-year experience in selected ten logistics and supply chain organizations in Thailand. The sampling techniques involved judgmental, convenience and snowball sampling. Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) were employed to assess and validate the model's adequacy and to conduct hypothesis testing. Results: The findings reveal that ICT use significantly influenced entrepreneurial orientation and innovation but has no significant influence on organizational performance. Additionally, innovation was significantly influenced by collective entrepreneurship but not by entrepreneurial orientation. Finally, innovation significantly influenced organizational performance. Conclusions: The study concludes with actionable insights for logistics and supply chain organizations in Thailand. This research serves as a valuable resource for practitioners, policymakers, and researchers seeking to advance the understanding of organizational dynamics in this critical industry.

Purpose: The purpose of the current study is to highlight the drivers of corporate environmentally and socially sustainable performance among different players including airlines, caterers, suppliers and logistics companies in the flight catering supply chain. Research design, data and methodology: Based on a qualitative research approach this study employed in-depth semi-structured interviews exploring the drivers of corporate sustainable performance with management from major in-flight catering stakeholders (n=23) from the perspective of constructivism. Using the snowball sampling approach, interviewees were carefully chosen to represent a diverse range of supply chain contexts (airlines, catering, non-food suppliers, and logistics companies). Results: By focusing on the complex context of multiple supply chain partners, the study identified a range of complex relationships between the drivers of sustainable performance in the supply chain: firm-led drivers, factors influencing firm-led drivers, partial influencers, and additional factor, cost. Conclusions: This study emphasizes that some drivers do not play an absolute role and has highlighted that there is a need for companies to change the attitude, that is to pay more than 'lip service' to improving sustainable performance. This study develops a theoretical framework of the drivers of corporate sustainable performance, along with its practical industry implications.

기존의 리더십과 관련된 연구들은 대부분 조직 내부의 부하와 상사간 관계에 초점을 맞추고 있다. 이는 조직간 거래관계가 기업의 주요한 성패요인이 된 현시점에서 조직 간 리더십에 대한 연구의 필요성을 제기하는 현상이라 할 수 있다. 특히, 조직 간 거래관계가 분석의 초점인 공급체인 연구에서는 이러한 조직 간 리더십에 대한 연구가 더욱 필요하다 할 수 있다. 따라서 공급체인의 조직간 리더십을 연구하는 것은 매우 중요하다 할 수 있다. 하지만 기존 공급체인 리더십 관련 연구들은 두가지 중요한 문제점을 가지고 있다. 첫째, 대부분의 연구들이 공급체인 리더십과 성과 간의 관계에 초점을 맞추고 있다는 점이고, 둘째, 기존 공급체인 내 조직간 리더십 연구들은 리더십과 재무성과 간 관계를 거의 다루지 않았다는 점이다. 이에 본 연구는 공급체인 리더십의 선행변수를 발견하고, 리더십-성과 간 관계에 영향을 미칠 가능성이 있는 조절변수를 실증하였다. 특히, 본 연구에서 관심이 있는 공급체인 리더십의 선행변수는 최근 그 중요성이 강조되고 있는 관계적 행동 변수를, 리더십-성과 간 관계의 조절변수로는 리더의 윤리성을 검정하였다. 국내 5대 편의점에 상품을 공급하는 공급업체 납품담당자 217명을 대상으로 설문조사를 실시하였고, PLS(Partial Least Square) 분석방법을 통해 분석한 결과 대형 유통업체의 관계적 행동 중 교육훈련, 공정한 보상, 조직간 의사소통은 공급체인 리더십을 강화하였고, 공급체인 리더십은 공급업체의 재무성과를 강화하는 것으로 나타났다. 또한 대형 유통업체의 윤리성이 높은 경우 공급체인 리더십이 공급업체 재무성과를 더 강화시키는 것으로 나타났다. 반면 대형 유통업체의 관계적 행동 중 비전제시는 공급체인 리더십에 영향을 미치지 않았다.

In supply chain management, the supply contract can induce collaboration and coordination among the supply chain members in order to optimize supply chain performance. Numerous supply contracts have been examined; however, some difficulties related to the application of these contracts still occur. One of the solutions is to apply the composite supply contract which can assist in the supply chain coordination. This research examines the composite contract of the revenue sharing and quantity flexibility contracts in a two-stage supply chain, which comprises a retailer and a supplier. In this research, a mathematical model of the composite contract is developed; then, the applicability of the proposed composite contract is examined by investigating its capability in terms of supply chain coordination and profit allocation. In the numerical experiments, the composite revenue sharing-quantity flexibility contract showed that it is superior to both component contracts in terms of supply chain coordination and profit allocation among supply chain members.

Supply Chain (SC) can balance demands with supply activities as executing Supply Chain Planning (SCP). The fluctuated demands, however, will break the balance between demand and supply. It means that the present SCP is useless in responding the changed demands. Thus it is necessary for SCP to be updated with changed demands. We call this procedure as Supply Chain Replanning. However, the existing measures for SC can not deal with the balance between supply and demand so that they can not detect effectively the timing of replanning. For this reason, a new performance measure, Balancing Point, is developed using momentum, a concept of Physics. It can treat the balance between supply and demand. Also, a replanning method based on Balancing Point is proposed. The proposed method is more effective than the existing replanning method, periodic replanning method and net inventory method.

Purpose - The goal of this research is to examine the influence of Quick Response on the supply chain performance. Furthermore, this study investigates the potential of Quick Response to be a more advanced form of supply chain collaboration program with extensive information sharing activities. Research design, data, and methodology - The mathematical model is developed to represent the two stage supply chain system with a single manufacturer and one retailer. In the numerical study with the proposed mathematical models, three supply chain systems including the traditional system, Quick Response, and the fully shared information system are compared in terms of their profits. Results - The numerical analysis shows both manufacturer and retailer obtain greater profits under Quick Response than in the traditional system. While the fully shared information outperforms Quick Response as well as the traditional system, it results in lower manufacturer's profit compared with Quick Response. Conclusions - According to the numerical examples, Quick Response is the effective supply chain collaboration program that is beneficial to every supply chain member. The fully shared information system, as a more advanced form of collaboration than Quick Response can bring more benefits to the whole supply chain system, but it is necessary to prepare the proper incentive program that enables every member to share its benefits equally.

Purpose: This study investigates the influence of VMI on the supply chain performance over time. By examining each supply chain member's ongoing performance, this study figures out how VMI allows the vendor to overcome the initial loss and eventually provides the benefit to every supply chain member. Research design, data, and methodology: The proposed mathematical model describes the supply chain system where a manufacturer and a retailer make the operational decisions to maximize their own profits. By using the numerical examples with arbitrary data, VMI and non-VMI are compared in terms of their profit changes over time. Results: The numerical analysis shows that VMI results in greater overall profits for both manufacturer and retailer than non-VMI, while the manufacturer make a loss in the early stage of VMI implementation. This study also examines the impacts of certain conditional factors on the performance of VMI. Conclusions: This study supports the idea that VMI leads to manufacturer's initial loss but it brings greater profits to both manufacturer and retailer than non-VMI after all. In addition, the result of this study provides the managerial implications about the particular condition that allows VMI to achieve a significant financial performance improvement over non-VMI.
