The purpose of this paper is to present and test a methodology, extending the concept of hierarchical Petri nets, to discover conflicts in a distribution channel.

The approach involves linking different levels of the supply chain and detecting conflicts occurring when the single entities, each optimized for its own operations, are combined together in a supply chain. Specifically, a methodology is proposed for synthesizing individual Petri Net models combined with matrix equations in order to detect and manage conflicts in a supply chain. These conflicts may stem from differing goals, planning and resources.

The methodology offers the user the ability to investigate the potential for conflicts in the system and manage the system to avoid such conflicts before they occur. The proposed approach holds promise for both the short term and long term for effective supply chain management and design. This would enable the supply chain to put sufficient protection (e.g. buffers) in strategic locations relative to the potential conflict or contingency plans in place to handle the conflict when it occurs.

While the ability to discover and pre‐empt conflicts would be a valuable asset to the management and design of supply chains, there is little insight found, to date, in the research on effective methods to realize detection. The current paper provides a systematic approach through the development of a hierarchical Petri net extension to detect conflicts prior to occurrence in an integrated supply chain system.

The necessity to assess and manage supply chains to be free from social problems such as human and labour rights abuses has become particularly apparent since the introduction of conflict minerals regulations in the United States (Dodd-Frank Act) and the European Union. Similarly, stakeholders demand that products are free from social problems. Ever more companies are therefore challenged to assess and manage social issues in their supply chains. At the same time, the increasing literature on assessment and management of social issues is disperse and an overview missing. This paper aims to provide an overview of the existing literature on social assessment and management approaches relating to conflict minerals and connected to social issues in supply chains.

A review of the academic literature on social assessment and management of conflict minerals to provide an overview is currently missing. This paper addresses this gap by systematically reviewing the existing research literature on approaches for the social assessment and management of conflict minerals from a supply chain perspective.

The systematic literature review found 21 social assessment and 30 social management approaches with reference to conflict minerals, with the most referenced approach being the OECD guidelines. Overall, the conflict mineral related literature discusses rather general social assessment and management approaches, such as codes of conduct, while the effectiveness of the approaches is not analysed in depth. The paper finds that an analysis of the effectiveness and interlinkages of different approaches is missing. The large variety of social and human rights issues addressed in the academic literature ranges from corruption to violence, going beyond the scope of regulations focused on conflict minerals. This indicates that regulations on conflict minerals and the consequences for management are seen as a specific case with wider implications for future regulations and the necessity for management to solve social problems in supply chains in an effective way.

The review paper is conceptual and develops a framework to classify social assessment and management approaches for conflict minerals, drawing on the supply chain management literature.

The overview reveals that research refers to broader social assessment and management approaches indicating wider implications for assessing and managing social issues in supply chains in general, irrespective of whether they are conflict mineral related. Research has, however, so far not addressed the effectiveness and interlinkages between social assessment and management approaches. The aim of the emerging regulations, however, is to foster more effective management of social issues in supply chains. Management is therefore challenged to develop and implement innovative approaches to effectively reduce social problems in supply chains beyond conflict minerals. Conclusions are drawn for management and research.

The paper highlights the need for collaboration with NGOs, industry associations and suppliers, recommending to engage in supplier development.

The paper conducts the first systematic review of academic literature on conflict mineral related social assessment and management approaches. A framework is proposed to classify social assessment and management approaches based on supply chain management literature. While conflict minerals often represent a small fraction of components in a product, they can have huge and costly implications for companies, which require (potentially) large changes for the sourcing and supply strategy of a company. Conflict mineral regulations represent the first attempt to regulate social and human rights abuses in supply chains holding companies responsible for misconduct caused by suppliers abroad.

The literature on supply chain management has focused on the benefits of frequent and strategic communication in supply chains. However, it has paid much less attention to the difficulties and conflicts associated with day‐to‐day communications in supply chains. This discrepancy is surprising because operational communications play a crucial role in supply chain management. In this paper, the aim is to investigate when operational, day‐to‐day communications in supply chains become linked with conflicts and how these conflicts can be prevented.

The authors surveyed respondents from the partner firms of 81 different supply chains. The data from 380 surveys were examined with moderated regression analyses.

The findings indicate that operational communications are linked with conflicts if upstream parties in supply chains do not recognise the importance that their downstream partners attach to certain performance objectives.

First, the paper goes beyond the benefits of communication and demonstrates that communication in supply chains can also have drawbacks. Moreover, the paper shows how upstream goal recognition helps parties avoid conflicts in their day‐to‐day communications.

The study points to the importance of developing upstream goal recognition in supply chains and provides several suggestions to promote upstream goal recognition.

The paper contributes to supply chain communication research by going beyond the benefits of communication and highlighting the difficulties that can accompany day‐to‐day operational communications. Moreover, it provides an explanation for the conditions under which operational communications are associated with conflict.

The new geopolitical context being created by the Ukraine–Russia war highlights the need for structured approaches to planning and implementing unhooking strategies and developing associated supply chain reconfigurations.

The authors have interviewed six supply chain executives to begin the investigation of the key supply chain risks and disruptions caused by the Ukraine–Russia war.

Initial corporate responses to the Ukraine–Russia conflict were significant, perhaps unprecedented. However, as institutional, corporate and consumer sentiment influence reconfiguration responses, the authors have identified three supply chain pathways that underpin unhooking actions.

The authors selected respondents from each different type of supply chain interaction with the conflict zone (inbound, outbound and within), covering both components/intermediate products and finished goods. Therefore the sample size was small and designed to fit in with the spirit of the pathway initiative.

The authors reinforce the key role of procurement and supply chain management in not just supply but also in downstream markets that can accelerate decoupling and mitigate the associated supply chain disruptions.

The authors observe that supply chains are increasingly being weaponized, as external institutional and consumer influences necessitate companies to unhook from conflict zones, countries, or regimes. They are becoming increasingly intertwined with foreign policy.

The novelty of the contribution to the associated discourse is the perspective that after decades of increasing globalization and geographic dispersion of supply chains, the unhooking effort is not limited to a firm and its internal operations but involves multiple stakeholders. For instance, the full extent of the complex linkages of supply chains, networks and relationships that touch conflict zone geographies must be considered, particularly those that are incompatible with the firm's values and aims, including those of their stakeholders.

The purpose of this paper is an attempt to design a proper incentive coordination mechanism to deal with the channel conflicts between the traditional sales and online direct sales.

With respect to the problems of channel conflicts between the traditional sales and online direct sales, to optimize the sale system and get more profits, considering the influences of consumer network acceptance, the authors establish demand and profit function based on consumer's utility, respectively. What's more, we exploit the game theory to analyze the optional decisions of the supply chain under the incentive coordination condition and no incentive coordination condition, and then we discuss the supply chain's optimal pricing, demand, profit and compensation incentive levels with the different effect of consumer network acceptance.

The level of compensation incentive provided by the manufacturer is influenced by consumer network acceptance and product cost. The lower the consumer network acceptance, the better the compensation incentive coordination effect of manufacturers. Manufacturers, wholesalers, retailers and consumers are all important players in real supply chain relationships. When a manufacturer exists as a dominant role, it should pay full attention to the impact of consumer behavior on supply chain decisions.

The research can clarify the influence and mechanism of consumer behavior on supply chain channel conflict coordination, and deal with channel conflicts.

The proposed incentive coordination can effectively realize supply chain channel conflict resolution, and provide decision-making ideas and methods for manufacturers to develop the supply chain management of online direct sales channels.

Literature on conflict minerals supply chain management issues has witnessed a significant surge during the last decade. The authors review how CM research addressed supply chain issues over the last decades and present a critical assessment of such literature based on supply chain governance theory.

A systematic literature review approach was adopted, and a sample of 122 papers were identified in relevant journals. A descriptive, thematic and content analysis of the papers is presented to delineate the structure and the main research clusters of the literature.

The authors provide a comprehensive assessment of CMSC literature and identify four main research clusters. Most research has focussed on operational practices and adopted a fragmented approach to CMSC issues. Accordingly, the authors provide research propositions related to under-explored aspects in extant literature.

This study has a number of implications. Practitioners and researchers will gain a greater understanding of specific CMSC issues which have been addressed in current literature and of how responsible CMSC actions can be implemented.

This study is one of the first literature reviews of publications on CMSC from a supply chain governance perspective. This review presents an overarching map of CMSC literature and a series of propositions to inform future research.

Drawing on the relational view and contingency theories, this study explores supply chain relationship conditions' roles in interrelationships between environmental, social and supply chain performance (SCP), i.e. triple bottom line (TBL).

The data from industries and structural equation modeling (SEM) were used to validate the proposed model. Interviews with industry experts were conducted to further understand the findings.

The authors find that relationship conditions, such as inventory information sharing, dependency, opportunistic behavior and conflicts, moderate TBL linkages. Interestingly, power asymmetry does not moderate the linkages. Social performance mediates between environmental and SCP. This indirect effect is stronger than the effect of environmental performance on SCP.

This research is perhaps the first to bring a much-needed nuanced view on the importance of relationship conditions for TBL performance linkages. The research further underlines the importance of social performance in an emerging economy.

The purpose of this paper is to illustrate how a focal firm can manage sustainability in its lower-tier suppliers which lie beyond the firm’s visible horizon.

This paper presents a new approach to managing sustainability in multi-tier supply chains with an illustrative case study that analyzes how electronic equipment firms make efforts to verify that they are not using conflict minerals.

The nexus supplier (smelters in the electronics supply chain) plays a relevant role in increasing visibility and tracing the source of minerals, thus guaranteeing sustainability upstream in the supply chain.

The paper is based on a specific supply chain (i.e. electronics supply chain) and therefore its conclusions might be only partially generalized to other sectors.

Firms in complex supply chains need to make efforts to identify and manage nexus suppliers to extend sustainability upstream in the supply chain, especially beyond their visible horizon.

The paper focuses on management of sustainability in the invisible zone of the supply chain, which has been neglected in previous literature and is increasingly important to the managerial world in an economy with a growing number of global supply chains.

This conceptual paper aims to explore how supply chain managers deal with social threats to supply chains, in the process of demonstrating the potency of a largely neglected strand of realist social theory. This theory, as posited, sheds a great deal of light on the behavioural reality of how supply chain managers operate within the social aspects of their risk environments.

The paper is presented as a narrative synthesis of classical realist sociological literature.

The Machiavellian approach provides a template that can be used to help academics and practitioners understand how and why supply chain managers orient themselves to the social threats they confront in very different ways. The theory’s contention that the behavioural reality can be subdivided between two basic patterns allows it to serve as a constructively simple template for becoming attuned to ways in which supply chain managers socially construct and act within their social threat environments.

The growing social complexity of supply chains gives behavioural responses a complexity reduction function. The authors theorise that such patterns, once activated, may not necessarily adapt rationally as guides to optimise the chance of success against the full range of social threats they are likely to encounter.

Cross-disciplinary supply chain management research is increasingly drawing upon sociology and behavioural science to facilitate greater understanding of not only the supply chain environment but also the roles of supply chain managers as relationship influencers and managers of conflict. The authors posit that Machiavellian–realist social theory can contribute to supply chain management scholarship by offering a constructively simple approach to evaluate the behavioural realities associated with social threats.

The purpose of this paper is to understand conflicts that emerge between managers of buying and supplying firms when a personal relationship (friendship, etc.) is present between them in the supply chain context.

This research uses a case study methodology and relies on data obtained from 30 qualitative interviews with managers of buying and supplying firms, having a personal relationship within inter-firm relationships to promote the interest of the firm.

Results from this study reveal conflicts between managers of buying and supplying firms due to the presence of a personal relationship between them. Specifically, results suggest that managers face ego conflict, supplier’s selection conflict and conflict on accepting late deliveries when they rely on personal relationships, which are themselves embedded within inter-firm relationship.

This study has some limitations. First, this study examines behavioural patterns in Australian cultural context. Second, results of this study are not generalizable to a broader population.

Firms can use the findings to understand conflicts, which arise between managers of buying and supplying firms, as a result of a personal relationship between them in the supply chain.

This is, perhaps, the first study contributing to the supply chain relationship literature by unveiling conflicts between managers of buying and supplying firms, when a personal relationship is present between them.
