Purpose The purpose of this paper is twofold: first, to discuss key challenges associated with the use of either simulation or real-world application of intelligent autonomous vehicles (IAVs) in supply network operations; and second, to provide a theoretical and empirical evidence-based methodological framework that supports the integrated application of conceptualisation, simulation, emulation and physical application of IAVs for the effective design of digital supply networks. Design/methodology/approach First, this study performs a critical review of the extant literature to identify major benefits and shortcomings related to the use of either simulation modelling or real-word application of physical IAVs. Second, commercial and bespoke software applications, along with a three-dimensional validation and verification emulation tool, are developed to evaluate an IAV’s operations in a conceptual warehouse. Third, a commercial depth-sensor is used as a test bed in a physical setting. Findings The results demonstrate that conceptual and simulation modelling should be initially used to explore alternative supply chain operations in terms of ideal performance while emulation tools and real-world IAV test beds are eminent in validating preferred digital supply chain design options. Research limitations/implications The provided analysis framework was developed using literature evidence along with experimental work and research experience, without consulting any industry experts. In addition, this study was developed based on the application of a single physical device application as a test bed and, thus, the authors should further progress with the testing of a physical IAV in an industrial warehouse. Practical implications The study provides bespoke simulation modelling and emulation tools that can be useful for supply chain practitioners in effectively designing network operations. Originality/value This work contributes in the operations management field by providing both a multi-stage methodological framework and a practical “toolbox” for the proactive assessment and incorporation of IAVs in supply network operations.

PurposeSupply chains need to balance competing objectives; in addition to efficiency, supply chains need to be resilient to adversarial and environmental interference and robust to uncertainties in long-term demand. Significant research has been conducted designing efficient supply chains and recent research has focused on resilient supply chain design. However, the integration of resilient and robust supply chain design is less well studied. The purpose of the paper is to include resilience and robustness into supply chain design.Design/methodology/approachThe paper develops a method to include resilience and robustness into supply chain design. Using the region of West Africa, which is plagued with persisting logistical issues, the authors develop a regional risk assessment framework and then apply categorical risk to the countries of West Africa using publicly available data. A scenario reduction technique is used to focus on the highest risk scenarios for the model to be tractable. Next, the authors develop a mathematical model leveraging this framework to design a resilient supply network that minimizes cost while ensuring the network functions following a disruption. Finally, the authors examine the network's robustness to demand uncertainty via several plausible emergency scenarios.FindingsThe authors provide optimal sets of transshipment hubs with varying counts from 5 through 15 hubs. The authors determine there is no feasible solution that uses only five transshipment hubs. The authors' findings reinforce those seven transshipment hubs – the solution currently employed in West Africa – is the cheapest architecture to achieve resilience and robustness. Additionally, for each set of feasibility transshipment hubs, the authors provide connections between hubs and demand spokes.Originality/valueWhile, at the time of this research, three other manuscripts incorporated both resilience and robustness of the authors' research unique solved the problem as a network flow instead of as a set covering problem. Additionally, the authors establish a novel risk framework to guide the required amount of redundancy, and finally the out research proposes a scenario reduction heuristic to allow tractable exploration of 512 possible demand scenarios.

Supplier Relationship

Purpose – This purpose of this study is to provide empirical evidence of how cooperation is related to suppliers’ performance, a relationship that is thought to be affected by the type of customer and the extent to which the market is diversified. It analyzes horticultural exporting firms in southeastern Spain, which are the main suppliers of European markets. Together with their primary customers (large-scale retail companies such as Carrefour, Tesco and Aldi), these firms constitute a complex supply network composed of a variety of agents and sales channels. This network will be studied from the perspective of the supplier–supplier relationship that is critical to their survival. Design/methodology/approach – Starting with a detailed description of Europe’s vegetable supply chain, a hierarchical regression is used with an index of cooperation intensity, moderated by retail sales and market concentration. The authors test the hypotheses using panel data on a set of 118 horticultural marketing firms in southeast Spain for the period 2009-2011. Findings – Cooperation strategies are shown to have positive effects on performance (market creation, promotion, quality, training, joint supply purchases and research ventures). Moreover, the retail channel and market diversification are observed to have a positive effect on the relationship between cooperation and the supplier’s performance. They demonstrate that active cooperation strategies have a greater bearing on performance in those firms whose primary customers are retailers. This circumstance provides evidence of the synergies and benefits that may arise when the supplier integrates the retailer in the supply chain, but which do not arise with other types of customers. Research limitations/implications – Although this study refers to a specific sector (fruits and vegetables) and the statistical results are limited, they provide insights that may assist in understanding how other perishable produce-related industries work: such industries share many common features. Practical implications – A more stable relationship between suppliers and retailers in the perishable produce market will render the supply firm more cooperative, competitive and profitable. Increased performance does not arise from the better conditions and improved sales power offered by the customer but instead from the adaptability of the supplier. Likewise, market diversification drives the supply firm toward a cooperative strategy, making it more profitable and competitive. As a practical norm, market diversification alone will not have positive results on performance unless the firm proves capable of enhancing its capacity for cooperation. Social implications – Proper management of the agricultural produce supply chain has repercussions on all of the members of that chain, although special emphasis should be placed on producers and consumers. The availability of food, its quality and its safety depend on management during the production phase. Along these lines, and more specifically for the consumer, this work is relevant because the sector analyzed accounts for 40 per cent of the vegetables consumed in Europe. Originality/value – This article defends the supplier–supplier relationship as the starting point for the analysis of a supply network. In certain sectors, the suppliers’ ability both to solve their clients’ problems and to be profitable is conditioned on maintaining the network and, therefore, the basic focus must center on analyzing their relationships, always including the customer, who has a direct or indirect influence on those relationships. Previous research has not comprehensively addressed this issue, let alone that of a sector with agile and perishable products in which, due to its nature, decision-making about market destinations and sales channels is the order of the day.

Purpose From the perspective of the economic theory of complementarity, the purpose of this paper is to examine how internal collaboration and external competencies would provoke and strengthen each other, and subsequently enhance organizational innovation capability. Design/methodology/approach The survey data were collected from 201 manufacturing firms and checked for common method variance, validity and reliability. Structural equation modeling was then used to test the hypothetical complementarity effect. Findings The results suggest that internal collaboration (as a manifestation of exploitative learning) and external competencies, which include supply network flexibility and supplier operational capabilities (as manifestation of exploratory learning), do in fact compensate for each other’s deficiencies. Complementary deployment of internal collaboration and external competencies enhances each other’s contribution to innovation capability. Practically, the study indicates that organizations should consider making concerted efforts to develop internal collaboration, supply network flexibility and supplier operational capability as a bundle. Originality/value Extensive discussions exist in the literature on exploration and exploitation being essential components of innovation and their conflicting impact on innovation efficiency and effectiveness. But how an organization should operationally develop supply chain competencies in order to maximize overall innovation capability still remains largely an unanswered question. The current study advances the research on the inter-relationships between exploration and exploitation by empirically demonstrating the complementary nature of internal collaboration and external competencies in developing sustainable innovation capabilities.

Supply Chain Resilience

Purpose In few prior empirical studies on supply chain resilience (SCRES), the focus has been on the developed world. Yet, organisations in developing countries constitute a significant part of global supply chains and have also experienced the disastrous effects of supply chain failures. The purpose of this paper is therefore to empirically investigate SCRES in a developing country context and to show that this also provides theoretical insights into the nature of what is meant by resilience. Design/methodology/approach Using a case study approach, a supply network of 20 manufacturing firms in Uganda is analysed based on a total of 45 interviews. Findings The perceived threats to SCRES in this context are mainly small-scale, chronic disruptive events rather than discrete, large-scale catastrophic events typically emphasised in the literature. The data reveal how threats of disruption, resilience strategies and outcomes are inter-related in complex, coupled and non-linear ways. These interrelationships are explained by the political, cultural and territorial embeddedness of the supply network in a developing country. Further, this embeddedness contributes to the phenomenon of supply chain risk migration, whereby an attempt to mitigate one threat produces another threat and/or shifts the threat to another point in the supply network. Practical implications Managers should be aware, for example, of potential risk migration from one threat to another when crafting strategies to build SCRES. Equally, the potential for risk migration across the supply network means managers should look at the supply chain holistically because actors along the chain are so interconnected. Originality/value The paper goes beyond the extant literature by highlighting how SCRES is not only about responding to specific, isolated threats but about the continuous management of risk migration. It demonstrates that resilience requires both an understanding of the interconnectedness of threats, strategies and outcomes and an understanding of the embeddedness of the supply network. Finally, this study’s focus on the context of a developing country reveals that resilience should be equally concerned both with smaller in scale, chronic disruptions and with occasional, large-scale catastrophic events.

Purpose The purpose of this paper is to explore sustainability and collaboration in supply chain (SC) management designs and to develop a sustainable supply chain design (SCD) model. Design/methodology/approach First, a literature review of the principal theories and SC management approaches is discussed. Second, the development of a sustainable SCD model is described and explained. Third, the results and the operationalization of the model, which incorporates sustainable procurement elements based on the results of interviews from a case study, are outlined. Findings A framework is proposed to provide managers, practitioners and academics with a practical solution to make sustainable SC decisions in a more structured and consistent manner. Originality/value The paper presents a currently discussed problem about the design of differentiated supply chains to avoid or offset the effects of allocation issues in the electronic marketplace. Although past literature reviews provide valuable results, they were based upon the assessment of supply chain decisions failing to consider the sustainable corporate social responsibility and the interaction criteria. The findings from this study highlight the importance of addressing supply chain decisions in a structured manner and prioritize the development of dynamic capabilities to improve the firm’s ability to reconfigure internal and external competences to address rapidly changing environments and reinforce a collaborative SC management system with third parties.

Starting Point

This paper contemplates the supply chain design problem of a large-scale company by considering the maximization of the Net Present Value. In particular, the variability of the demand for each type of product at each customer zone has been estimated. As starting point, this paper considers an established supply chain for which the main problem is to determine the decisions regarding expansion of distribution centers. The problem is solved by using a mixed-integer linear programming model, which optimizes the different demand scenarios. The proposed methodology uses a scheme of optimization based on the generation of multiple demand scenarios of the supply network. The model is based on a real case taken from a multinational food company, which supplies to the Colombian and some international markets. The obtained results were compared with the equivalent present costs minimization scheme of the supply network, and showed the importance and efficiency of the proposed approach as an alternative for the supply chain design with stochastic parameters.

The Impact

Purpose The purpose of this paper is to evaluate the financial and material flows in cash-based responses (CBRs) and their implications for humanitarian operations. This research proposes to view cash as a commodity used by humanitarian actors in emergency operations and therefore aims to explore how CBRs impact on humanitarian logistics and ultimately, affect beneficiaries. Design/methodology/approach The methodological approach of grounded theory was chosen for this inquiry because it allowed the researchers to generate a general explanation for the process of CBRs in emergency situations based on the views of participants interviewed. Interviews were conducted with senior managers, supply chain managements and logistics officers from international humanitarian organisations (HOs), United Nations agencies and commercial organisations involved in humanitarian operations. Examples of topics covered during the field work included, procedures and policy; knowledge and information management; systems and technology; actors and agents. Findings The impact of CBRs on humanitarian operations can though not be understated. They alter supply chain design, the very role of beneficiaries as well as HOs, and change the strategy of aid delivery from push to pull. Perhaps, the most important factor is the elimination of many logistical activities that needed to be performed by HOs. Delivering cash diminishes the needs for lengthy procurement and assessment processes, pre-positioning, transportation and distribution. This bears the potential of significant reductions in costs for delivering humanitarian aid at the same time as it is an important move from aid to trade. Practical implications The challenge for humanitarian agencies in the coming years is to overcome their fears surrounding CBRs, and to implement cash programmes where they are judged to be the most appropriate response. This will require not only a change in donor policies, but also a fundamental change in the skill set of humanitarian logisticians, who are used to identifying needs and providing commodities and thus to maintaining control over the provision of assistance. Originality/value The contribution of this research is twofold: this is the first examination of cash-based interventions in humanitarian operations through the prism of supply chain management. Second, the research is field based and grounded in empirical observations thus adding to the literature and offering insights to practice.

PurposeThis research aims at investigating the common practical problem of how procurement can be transformed from tactical and administrative to becoming an organizational strategic partner and indeed a competitive weapon, using modern technologies in particular. We investigated how procurement can be reinvented, from being digitized to digitalized to digitally integrated, ultimately contributing in business terms beyond supply chain effectiveness but also to profit generation.Design/methodology/approachA case study approach was designed to investigate three firms, each at very different stages of digital maturity in procurement. Interviews with managers, investigation of processes and documentary materials and in-depth follow-up discussions were conducted.FindingsThe iterative digitalization transformation discovered encompasses complexities rooted in organizational structure, supply chain design and the management of the technology for employees' uptake. There are both operations and strategy implications as a result. This initial research phase led to mapping a model of digital maturity as well as identifying its underlying constructs.Originality/valueThis research discovered that the implementation of digital technologies can lead the procurement function of the supply chain to completely grow out of its administrative and clerical shell into a strategic, consultative, value-adding and potentially revenue-generating function, thereby contributing to the well-being of not only the supply chain but also the entire organization.
