Abstract

Purpose

The aim of this paper is to propose a genetic algorithms approach to develop a collaborative supply chain network, i.e. a supply chain network with genetic algorithms embedded (GA‐SCN), so as to increase the efficiency and effectiveness of a supply chain network.

Design/methodology/approach

The methodologies of the GA‐SCN are illustrated through a case study of a supply chain network of a Hong Kong lamp manufacturing company involving 10 entities, whose roles range from suppliers, purchasers, designers and manufacturers, to sales and distributors. A GA‐SCN is developed according to the information provided by the company, the performance results in the case study are discussed, and the concepts of network analysis are then introduced to analyze the equivalence structure of the developed GA‐SCN.

Findings

The genetic algorithms approach is a suitable approach for developing an efficient and effective supply chain network in terms of shortening the processing time and reducing operating time in the network: the processing time and operating cost are reduced by around 45 percent and 35 percent per order, respectively, in the case study.

Originality/value

This paper is the first known study to apply genetic algorithms for the development of a collaborative supply chain network to increase the competitiveness of a supply chain.

Abstract

In the context of a retailer with an international supply network, this paper develops theories of (a) how both stability and strong ties in an international supply network combine to yield a resource base that enables the development of flexible relationships with suppliers, (b) how stability and relationship flexibility in the international supply network of a retail reseller may in turn be driven both by the international diversity and by the density of the retailer’s supply network in a product category, and (c) how both the international diversity and the density of a retailer’s supply network may directly affect the likelihood of a retailer developing flexible relationships with its supplier. In doing so, this paper develops and presents six hypotheses and discusses some approaches to measurement of the underlying constructs and testing the hypothesized effects.

Abstract

Purpose

This paper aims to describe typical regional document supply networks in China through detailed discussion of their framework, service mode and influence on the nationwide document supply networks.

Design/methodology/approach

This paper highlights various kinds of regional document supply networks in China that serve as document resource sharing cooperation networks within provinces, cities and university towns. Their framework, service mode and influence on the nationwide document supply networks are discussed, followed by suggestions for improvement.

Findings

Regional document supply networks have their natural advantages in local financial support and extensive local coverage and are capable of providing fine service to meet various user needs timely and economically. They become an important part and beneficial supplement to nationwide document supply networks.

Originality/value

This paper studies regional document supply networks in China which has rarely been addressed in the international library literature.

Abstract

“Mirror Worlds” were suggested by David Gelernter based on a bold assertion: “You will look into a computer screen and see reality.” With mirror worlds, managers could be proactive, anticipating what might happen and acting accordingly, instead of waiting till events happen and then reacting. This paper extends the notion of mirrors worlds to supply chain management. In the case of supply chain management, managers could test the impact of making changes in their supply chains to study the impact.

However, mirror worlds could be extended to help actually monitor and manage supply chains to respond and adapt to changes in the world that affected the supply chain. In particular, mirror worlds could be “real” worlds if control for some of the activities between supply chain participants is in effect “turned over” to the mirror world. In that case, the mirror world would show the actual world, with the system making many of the decisions.

Abstract

Purpose

This paper aims to investigate the bridging role of first-tier suppliers in diffusing sustainability in supply networks and how this role is facilitated by the procurement function.

Design/methodology/approach

The paper is based on an embedded case study of two supply networks of a coffee beans roasting company. The embedded cases focus on coffee beans and packaging supply networks.

Findings

The findings reveal less than expected involvement of the focal company and its procurement function in sustainability implementation with first-tier suppliers. Instead, sustainability diffuses upstream to lower-tier suppliers but also downstream, against the tide, as a result of the various bridging roles performed by first-tier suppliers.

Research limitations/implications

This paper provides two theoretical contributions. First, it contributes to the sustainable supply network management literature by providing rich insights on sustainability diffusion to lower-tier suppliers and the role of first-tier suppliers in this process. Second, the paper contributes to structural hole theory by revealing a typology of bridging roles that actors, such as suppliers, undertake in the sustainability context.

Practical implications

The paper provides managers with practical insights on how sustainability can be diffused in the supply network and the different roles that first-tier suppliers can play in this direction.

Originality/value

This paper shows that sustainability diffusion to lower-tier suppliers is possible in the absence of focal company procurement involvement when bridging roles are undertaken by first-tier suppliers and their procurement functions are involved in the implementation process. These bridging roles facilitate sustainability diffusion both upstream and downstream.

Abstract

Purpose

The purpose of this paper is to examine how over-reliance on buyer-supplier relational capital (created through the interconnected supply chain and social network) impacts firm performance in the context of the emerging market, i.e. India.

Design/methodology/approach

The study uses the Prowess database (on Indian firms) to identify the firms that rely heavily on relational capital and employs panel data regression analyses to test the effect of relational capital on firm performance (supply chain performance and financial performance).

Findings

The results show that over-reliance on relational capital leads to lower supply chain performance (proxied by supply chain cycle) and financial performance (proxied by Tobin's Q). The results also reveal that supply chain performance mediates the relationship between over-reliance on relational capital and financial performance. Together, these results indicate that over-reliance on relational capital created through the interconnected supply chain and social network for supply chain management may negatively affect a firm's competitive advantage, which in turn can significantly impede its financial performance.

Originality/value

In light of the supply chain literature and relevant theories, the study develops an objective understanding of over-reliance relational capital created through the interconnected supply chain and social network, by relying on a large panel dataset of manufacturing firms and hence contributes to the supply chain literature. Also, it presents a novel idea to operationalize the measure for relational capital using the Prowess database.

Abstract

Purpose

Rethinking how to build resilience in supply chains is once again highlighted by COVID-19. Research on supply chain resilience has established flexibility as a firm-level antecedent that contributes to supply chain resilience. However, the authors know little about how supply chain flexibility is developed within a firm. Drawing on social capital theory, the authors claim that the way supply chain managers are embedded in their social networks plays a critical role in developing this antecedent. Specifically, the authors hypothesize that supply chain managers' structural and relational embeddedness in their reference network, comprised of individuals from whom they seek advice, is instrumental to developing supply chain flexibility, which subsequently enhances the firm's supply chain resilience.

Design/methodology/approach

Survey data collected from 485 manufacturing firms in Australia and Hayes and Preacher's (2014) parallel multiple mediator model were employed to empirically test the hypotheses.

Findings

The findings of the study establish that supply chain managers' structural and relational embeddedness in their reference network indeed have implications for developing supply chain resilience. Furthermore, the mediator through which managers' social embeddedness influences supply chain resilience is identified in the current study.

Originality/value

The study contributes to the extant literature on supply chain resilience, investigating the role that supply chain managers' social capital play in developing the resilience of their firm.

Abstract

Purpose

The purpose of the paper is to analyse how transport activities are embedded in supply chains and networks.

Design/methodology/approach

The paper is empirically grounded in a single case study that describes and analyses a supply chain of a particular product, Geocloth, focussing on how transport activities are organised in the supply network.

Findings

The paper concludes that transport activities are embedded in two related settings – the supply chain setting and the transport network setting – with implications for how adjustments can be made to increase transport performance. Furthermore, the paper shows how transport performance can be analysed as a function of how business relationships are connected vertically (i.e. how transport activities are sequentially connected within supply chains) and horizontally (i.e. how transport activities are connected across supply chains with regard to joint resource use).

Originality/value

The paper contributes to the understanding of how transport is integrated in supply networks by focussing on the connections between business relationships in supply chains and by pointing to how transport activities are embedded both in supply chain settings and in transport network settings.

Abstract

Purpose

The purpose of this paper is to examine the use of V‐A‐T analysis in the management of supply chain networks.

Design/methodology/approach

The paper provides a conceptual overview of V‐A‐T analysis as a procedure for categorizing manufacturing facilities, and explores the use of V‐A‐T analysis as a technique for the management of supply chain networks.

Findings

There are several challenges to the effective management of supply chain networks. However, organizations can overcome these challenges by understanding the nature of network control points as revealed through the application of V‐A‐T analysis on their supply chains.

Research limitations/implications

The paper is conceptual in nature and must be validated through empirical research studies.

Practical Implications

The concepts presented can be used by supply chain professionals to increase the likelihood of effective supply chain management within their organizations, and by supply chain researchers to further explore the use of V‐A‐T analysis as a tool for examining supply chain networks.

Originality/value

The paper makes a start in filling a void in the literature concerning how V‐A‐T analysis can be used as a tool to facilitate improved supply chain management.

Abstract

Purpose

Catastrophic supply chain disruptions can significantly damage the operational and financial performance of firms. While a growing body of literature on supply network structures has studied what influences supply networks' vulnerability to supply chain disruptions and capability to recover from them, it remains unclear how supply network structures change after major supply chain disruptions. We aim to provide an understanding of how these changes occur.

Design/methodology/approach

Using a natural experiment approach and supply network data from Factset, this study investigates how firms' supply network structures change after experiencing the catastrophic supply chain disruptions caused by the 2011 Tohoku earthquake and tsunami in Japan. We capture post-earthquake supply network changes using the measures of degree centrality and ego network density.

Findings

The results of the analysis suggest that compared to unaffected firms, the affected firms experience changes in their supply network structures tending toward lower complexity measured by in-degree centrality, out-degree centrality and ego network density.

Originality/value

This study contributes to social network theory and the complex adaptive supply network literature by providing empirical evidence of structural changes in supply networks after catastrophic supply chain disruptions. A managerial contribution is made by providing a reflection on why these changes might be occurring and alert firms to the challenges of managing complexity in their supply networks.
