An Alternative to Optimize the Indonesian\u27s Airport Network Design: AnApplication of Minimum Spanning Tree (MST)Technique

Abstract: Using minimum spanning tree technique (MS\u27!), this exploratory research was done to optimize the interrelation and hierarchical network design of Indonesian\u27s airports. This research also identifies the position of the Indonesian\u27s airports regionally based on the ASEAN Open Sky Policy 2015. The secondary data containing distance between airports (both in Indonesia and in ASEAN), flight frequency, and correlation of Gross Domestic Regional Product (GDRP) for each region in Indonesia are used as inputs to form MST networks. The result analysis is done by comparing the MST networks with the existing network in Indonesia. This research found that the existing airport network in Indonesia does not depict the optimal network connecting all airports with the .shortest distance and maximizing the correlation of regional economic potential in the country. This research then suggests the optimal networks and identifies the airports and regions as hubs and spokes formed by the networks. Lastly, this research indicates that the Indonesian airports have no strategic position in the ASEAN Open Sky network, but they have an opportunity to get strategic positions if 33 airports in 33 regions in Indonesia are included in the network

A collective mindfulness perspective of information sharing in the blood supply chain.

Purpose: This thesis aims to determine and unravel the underlying mechanisms of how inter-organisational information sharing influences blood safety and availability in the dyadic blood supply chain in normal, high tempo, and emergency conditions. Design/methodology/approach: Grounded in the critical realism paradigm and the perspective of high reliability theory particularly the collective mindfulness concept, this thesis uses an embedded multiple case study designed for theory elaboration. A combined retroductive-abductive and the basic qualitative description has been adopted as a research strategy. Two contrasting cases with three embedded cases for each main case are selected using convenient and context-based approaches, representing a centralised and tightly regulated blood supply chain in the UK as well as a decentralised and loosely regulated blood supply chain in Indonesia. The data are collected using the triangulation of semi- structured interviews, walkthroughs, and other supporting documents including artefacts and archives. Template analysis coupled with within-case and cross- case analyses are then used to analyse the data. Findings: This thesis finds that inter-organisational information sharing influences blood safety and availability through the dynamic enactments of collective mindfulness principles that reflect the inter-organisational information sharing behaviour across the operational conditions. It also finds that the blood supply chain actors in the centralised and tightly regulated context are collectively more mindful when sharing information than those in the decentralised and loosely regulated context, so that more positive changes in the blood safety and availability performance are observed in the former compared to that in the latter context. Interestingly, whilst the data reveal an emerging mechanism of heedful interrelating across a range of operational conditions, this thesis also reveals the fact that inter-organisational information sharing does not necessarily lead to positive changes in blood safety and availability. In fact, negatively enacted collective mindfulness principles can lead inter-organisational information sharing to unimproved and even potentially worse blood safety and availability performance. Originality/value: The primary contribution of this thesis lies in understanding the underlying mechanisms of how inter-organisational information sharing influences blood safety and availability in the dyadic blood supply chain across a range of operational conditions. Whilst offering practical and conceptually relevant knowledge to the blood supply chain literature, it informs the wider supply chain literature on the different collective mindfulness principles that make inter- organisational information sharing influence supply chain performance across a range of operational conditions. The use of the collective mindfulness concept offers a novel perspective that extends the current discussion on the effectiveness of that information sharing for supply chains.PhD in Leadership and Managemen

A refined framework of information sharing in perishable product supply chains

Purpose The purpose of this paper is to contribute to the understanding of the relationship between information sharing and performance of perishable product supply chains (PPSC). Building on transaction cost economics (TCE), organisational information processing theory (OIPT), and contingency theory (CT), this study proposes a theoretical framework to guide future research into information sharing in perishable product supply chains (IS-PPSC). Design/methodology/approach Using the systematic literature review methodology, 48 peer-reviewed articles are carefully selected, mapped, and assessed. Template analysis is performed to unravel the relationship mechanisms between information sharing and PPSC performance. Findings The authors find that the relationship between information sharing and PPSC performance is currently unclear, and there is inconsistency in the positioning of information sharing among constructs and variables in the IS-PPSC literature. This implies a requirement to refine the relationship between information sharing and PPSC performance. The review also revealed that the role of perishable product characteristics has largely been ignored in existing research. Originality/value This study applies relevant multiple theoretical perspectives to overcome the ambiguity of the IS-PPSC literature and contributes nine propositions to guide future research. Accordingly, this study contributes to the refined roles of relationship uncertainty, environmental uncertainty, information sharing capabilities, and perishable product characteristics in shaping the relationship between information sharing and PPSC performance

Improving blood safety and availability: a collective mindfulness perspective in the supply chain

Purpose – Maintaining a safe and available supply of blood requires a mindfully coordinated supply chain (SC) and is fundamental to the effective operation of health systems across the world. This study investigates how blood supply chain (BSC) actors demonstrate collective mindfulness (CM) principles in their operations and how these demonstrations lead to improvements in blood safety and availability (BSA) in different operational contexts. Design/methodology/approach – Six case studies drawn from two contrasting BSCs, the UK and Indonesia, which differ in structure and regulation are investigated in this research. Qualitative data are collected and analysed using template analysis. Findings – The cases reveal how the CM principles are demonstrated in the supply chain context in a range of operational conditions and their impact on BSA. The BSC actors in the more centralised and tightly regulated cases display more behaviours consistent with more of the CM principles over a greater range of operational conditions compared to those in the more decentralised and loosely regulated cases. As such, more improvements in BSA are found in the former compared to the latter cases. Originality/value – This paper is considered the first to investigate the demonstration of CM principles at the SC as opposed to the single organisational level. It proposes an alternative approach to understanding and evaluating reliability performance using behavioural rather than statistical principles

Response of Fresh Food Suppliers to Sustainable Supply Chain Management of Large European Retailers

This article analyses new supply chain management (SCM) strategies of the largest retail distribution chains in Europe within the context of differing sustainability concepts and approaches. An analysis is carried out of the strategic plans of such retailers, as well as recent developments in the sector. We begin by identifying the priority actions of retailers and then evaluating, by means of a survey, how small horticultural marketing firms (mainly cooperatives) in southeast Spain respond to the needs of these retailers. Subsequently, an analysis is carried out on these small marketing firm exporters to identify the relative weight which they assign to the variables assessed, while also considering the existing relationships between said weighted variables and business profits. Our results show that retailers tend to establish more simplified supply chains (that is, shorter and more vertical), essentially demonstrating their interpretation of a sustainable supply chain. In contrast, horticultural marketing firms have concentrated more on tactical and operational issues, thereby neglecting environmental, social and logistics management. Thus, their success rate in meeting the sustainability demands of their customers can be considered medium-low, requiring a more proactive attitude. Improved and collaborative relations, and the integration of sustainability concepts between suppliers (marketing firms) and their clients could contribute to successfully meeting sustainability demands. From the point of view of the consumer, close supplier–retail relationships have solved food safety issues, but the implementation of sustainability in other supply chain activities and processes is a pending issue. We propose strategic approximation and collaboration to bridge the gap between the varying sustainability demands in the supplier–retail relationship within perishable supply chains. Although this article specifically addresses fresh vegetable supply chains, the results may be extrapolated to other agri-food chains with a similar structure

Embracing scepticism as a non-physical form of redundancy: lessons learnt from the UK blood supply chain

This paper seeks to understand how supply chain actors demonstrate scepticism as a non-physical form of redundancy to maintain supply chain resilience. It provides lessons learnt from three case studies of dyadic blood supply chains involving three blood centres and twelve hospitals in England. This paper identifies three key elements of scepticism, namely information duplication, warranting, and cross-evaluation. These elements act as preventive mechanisms, avoiding the unwanted consequences of routine behaviour, and averting mindless actions resulting from reactive operations. We argue that scepticism can be adopted as a complement to supply chain redundancy practices, increasing the robustness and agility of supply chain operations, and therefore enhancing supply chain resilience. To the best of our knowledge, this is the first paper to address the notion of scepticism, emphasizing the pivotal role of human behaviour in the supply chain resilience literature. Despite its specific context, the findings could potentially be applied in other industries

The effect of small business leaders' organisational mindfulness and social learning on opportunistic behaviour to survive the COVID-19 pandemic

Purpose: This research aims to test the relationships between organisational mindfulness, social learning and opportunistic behaviour of small business leaders during the COVID-19 pandemic. Design/methodology/approach: Semi-structured interviews were conducted with six small business leaders from various sectors to explore and better grasp the unprecedented phenomenon. An online survey on small business owners and managers in Indonesia was then employed as the main study, resulting in 291 valid responses for further analysis. The data were analysed using regression on SmartPLS 3.0 software. Findings: This research finds that organisational mindfulness and social learning have positive and significant associations with the ability of small business leaders to discover and exploit opportunities. The path analysis suggests that organisational mindfulness plays a pivotal role as it also partially mediates the relationship between social learning and opportunistic behaviour. Originality/value: This is the first paper to test the relationships between organisational mindfulness, social learning and opportunistic behaviour, particularly in the context of COVID-19 pandemic. This work also contributes by emphasising the critical linkages between internal and external capabilities triggered by small business leaders to survive the pandemic. © 2021, Emerald Publishing Limited

Can information sharing predict fresh produce supply chain performance amid the COVID-19 pandemic? A social learning perspective

Purpose: This research aims to provide a predictive model assessment on the effect of information sharing on fresh produce supply chain (FPSC) performance during the COVID-19 pandemic by incorporating information quality as an important part of information sharing, as well as cognitive and affective appraisals as part of a social learning process (mediators) into the model. Design/methodology/approach: An online survey was conducted on 197 small fresh produce (fruits and vegetables) retailers in Indonesia during the COVID-19 pandemic. The data were analysed using Partial Least Squares Structural Equation Modeling (PLS-SEM) particularly PLSpredict supported by SmartPLS 4 software. Findings: This research reveals that information sharing is positively and significantly associated with information quality and that the two constructs are not directly associated with FPSC performance. The path analysis suggests that the effect of information sharing on FPSC performance is fully mediated by cognitive and affective appraisals to the information-sharing activity. It also suggests that the effect of information quality on FPSC performance is fully mediated by affective rather than cognitive appraisal. This model shows a high predictive power and highlights the pivotal role of the learning process during the COVID-19 pandemic. Originality/value: This research is the first to employ a predictive model assessment in PLS-SEM to empirically predict the effect of information sharing on FPSC performance using a social learning perspective, particularly in the context of the COVID-19 pandemic
