Abstract

Purpose

This study primarily aims to develop and solve an enhanced optimisation model for an assembly product multi-period inbound inventory routing problem (IRP). The many-to-one (inbound) model considers the bill of materials (BOM), supply failure risks (SFR) and customer demand uncertainty. The secondary objective is to study the influence of potential time-dependent model variables on the overall supply network costs based on a full factorial design of experiments (DOE).

Design/methodology/approach

A five-step solution approach is proposed to derive the optimal inventory levels, best sourcing strategy and vehicle route plans for a multi-period discrete manufacturing product assembly IRP. The proposed approach considers an optimal risk mitigation strategy by considering less risk-prone suppliers to deliver the required components in a specific period. A mixed-integer linear programming formulation was solved to derive the optimal supply network costs.

Findings

The simulation results indicate that lower demand variation, lower component price and higher supply capacity can provide superior cost performance for an inbound supply network. The results also demonstrate that increasing supply capacity does not necessarily decrease product shortages. However, when demand variation is high, product shortages are reduced at the expense of the supply network cost.

Research limitations/implications

A two-echelon supply network for a single assembled discrete product with homogeneous vehicle fleet availability was considered in this study.

Originality/value

The proposed multi-period inbound IRP model considers realistic SFR, customer demand uncertainties and product assembly requirements based on a specific BOM. The mathematical model includes various practical aspects, such as supply capacity constraints, supplier management costs and target service-level requirements. A sensitivity analysis based on a full factorial DOE provides new insights that can aid practitioners in real-life decision-making.

Abstract

Purpose

The purpose of this paper is to investigate the potential synergy between companies’ sustainable supply chain management (SSCM) activities and their supply chain resilience (SCRES). The authors propose hypotheses about the impact of buying companies SSCM activities on the inflicted damage by unexpected supply chain disruptions and the recovery time afterwards and test these empirically using data from companies during the global COVID-19 pandemic.

Design/methodology/approach

The authors investigate a sample of 231 of the largest publicly traded companies in the European Union with 4.158 firm-year observations. For the analysis, the authors generate variables capturing the companies’ intensity and years of experience of their SSCM activities targeted at the supply chain and run regression analyses on the inflicted damage due to the COVID-19 pandemic and the recovery time after the disruption.

Findings

Buying companies’ SSCM activities have a positive effect on their SCRES. The damage inflicted by unexpected supply chain disruptions is lower when companies have higher levels of SSCM and longer experience with it. The recovery time afterwards is significantly reduced by longer experience with SSCM efforts.

Research limitations/implications

The authors suggest SCRES is reinforced by transparency, situational awareness, social capital and collaboration resulting from companies SSCM activities translate into increased SCRES.

Practical implications

The authors show that companies with superior SSCM are more resilient in a crisis and conclude that, therefore, companies should invest in SSCM to prevent future supply disruptions.

Originality/value

To the best of the authors’ knowledge, this is the first empirical study analyzing a data set of multi-industry companies, linking their SSCM activities to SCRES during the pandemic.

Abstract

Purpose

This study aims to identify supply chain (SC) management practices applied to purchasing capable of improving the resilience of the health-care SC and mitigating the effects of material and service disruption during pandemics.

Design/methodology/approach

The approach adopted is qualitative and is based on a systematic literature review from the ScienceDirect, Emerald, Wiley and Web of Science databases. After selecting 705 documents, filters are applied, and 52 articles present problems faced by purchasing the health-care SC during the coronavirus disease 2019 (COVID-19) pandemic.

Findings

This article suggests five propositions of resilient practices that can increase purchasing resilience in the face of pandemics such as COVID-19. The proposed practices are collaboration, flexibility, visibility, agility and information sharing, which suggest a sequence for the adoption of management practices based on the number of occurrences and importance found in the analysed studies.

Research limitations/implications

This study does not find robust empirical evidence that could categorically state that the results can be replicated in organisations in general. Thus, as a continuation of research, more studies should use an empirical methodology and case analysis to organise different branches. As the human factor was decisive for the results observed in the literature, future research should dedicate part of the studies to the psychological area of professionals. Actions to combat the pandemic were implemented, impacting positively and negatively on the results obtained. Future research on combat actions could indicate which ones should be avoided.

Practical implications

As a result, disruptions are expected to be reduced, and consequently, the resilience of the SC will increase. Accordingly, purchasing processes and procedures can be redefined to positively influence the resilience of the health-care SC. Resilience is related to maintaining the flow of supply, as well as systems and actions aimed at mitigating the effects of disruptions in the hospital’s core business.

Social implications

Health systems need to respond to society’s needs even in the face of global crises, such as the one faced during the COVID-19 pandemic. The overload in hospitals and the exponential demand for specific medicines and services in the fight against the crisis caused by the COVID-19 pandemic require enormous coordination in procurement by the purchasing sector. This planning aims to ensure that the care provided by health services maintains the flow of value that serves hospitalised patients.

Originality/value

This study introduces a new approach to the recurrent problem of disruption of the health-care SC during a pandemic using a combination of five important management practices. This proves useful for mitigating disruptions and their effects on the health-care SC.

Abstract

Purpose

The study examines organizational security culture as the driver of supply chain security (SCS) practices (information management security, facility management security and human resource security). Additionally, the study examines the minimization of occurrence of supply chain disruption as the outcome of SCS practices.

Design/methodology/approach

A research model grounded on the contingency theory and the dynamic capabilities theory was developed and tested using partial least squares structural equation modelling (PLS-SEM). Data was obtained from 110 manufacturing and service firms in Ghana.

Findings

It was revealed that organizational security culture has a positive and a significant impact on information management security, facility management security and human resource security as hypothesized. In addition, facility management security significantly minimized supply chain disruption occurrence as hypothesized but information management security and human resource security did not.

Originality/value

To the best of the researchers' knowledge, this is the first study that examines organizational security culture as the driver of SCS practices. Additionally, the study is novel in examining the interplay between organizational security culture, SCS practices and supply chain disruption.

Abstract

Purpose

Food SMEs is the backbone of local and world economy. Even while food SMEs are aware of the potential advantages of implementing supply chain analytics (SCA), only a small number of companies use data-based decision-making. This is because of technophobia. In light of this, the purpose of this study is to investigate the factors that have an impact on SCA adoption which in turn influence the sustainable performance of firms.

Design/methodology/approach

The data were collected from 221 managers working in food-related SMEs in China by using a questionnaire-based survey. The framework of this study was validated using a rigorous statistical procedure using the technique, namely, partial least squares structural equation modelling.

Findings

The findings of this study suggest that all modified UTAUT components (i.e. performance expectancy, effort expectancy, social influence, facilitating conditions and technophobia) significantly influence SCA adoption. Moreover, the existing study highlights and confirms the significance of adopting SCA to improve sustainable performance.

Originality/value

This research is novel, as it extends and investigates the theoretical framework based on UTAUT theory in SCA context and its impact on sustainable organizational performance. In addition, the factor of technophobia is tested in SCA context. This study has several contributory managerial implications for food SMEs.

Abstract

The ability to satisfy customer demands while responding to relentless competitive pressure requires creative and often complex approaches to managing a firm's supply chain. Perhaps more than any other area, executive managers increasingly believe that a concept called globalization offers the best opportunity to achieve major performance gains. One area where many companies can begin to capture the benefits of globalization is global sourcing, which involves the worldwide integration of engineering, operations, and procurement centers within the upstream portion of a firm's supply chain. Unfortunately, capturing the benefits potentially offered by globalization is often limited by a lack of understanding concerning how to pursue this important topic. To help overcome this limitation this article presents a five‐level continuum that illustrates the differences between international purchasing and global sourcing, examines the factors that are the most critical to global success, and concludes with a brief discussion of future global sourcing directions.

Abstract

Purpose

The purpose of this paper is to present a framework for identifying various inbound supply-risk factors and analyzing its indicators considering the contextual relationship between them. This study additionally proposes a framework for developing an overall inbound supply-risk score considering a real-life case of the electronics supply chain (ESC) in the Indian context.

Design/methodology/approach

In total, 32 risk indicators are identified by a systematic literature review approach and are validated by supply chain practitioners/experts and further categorized into six main risk factors. A hybrid multi-criteria decision-making-based DANP (DEMATEL and ANP) framework is employed to develop the overall inbound-supply-risk score (ISRS) and to prioritize the risk indicators. Indian ESC is chosen as a viable case study to demonstrate the effectiveness of the proposed framework.

Findings

The outcomes from the study reveal that the overall ISRS in the ESC is 36 percent and additionally forewarns critical inbound-supply-risk factors such as supplier performance, product, and buyer organization. Further, the study also identifies the most significant risk indicators such as price margin, investment, on-time delivery, order fulfillment and design changes for ESC.

Research limitations/implications

Supply chain practitioners can adopt this framework as a useful inbound supply-risk assessment tool. Moreover, the hybrid framework will address subjectivity and interrelations among various factors through experts’ judgments. The results will assist the managers to have better insights on the critical risk factors and their complicated interrelationships and further strategize action plans to nullify the impact of incoming risks. This study mainly focused on risk identification and assessment of electronics inbound-supply-risk indicators in the Indian context. The framework can be used for other manufacturing and service industries, albeit the results derived are in the context of a developing country.

Originality/value

This paper provides an effective risk assessment framework for the supply chain practitioners/managers to develop a decision-support system for inbound-supply-risk quantification and prioritization of risk factors in the context of the ESC.

Abstract

This research applies the construct of bullwhip effect in a non‐traditional context. It is explored in intra‐organisational echelons. It is argued that the bullwhip effect in a company's inventory management of inbound and outbound logistics flows depends in part upon the gap between the degree of speculation and postponement of business activities. It is also argued that the bullwhip effect is caused by the value adding of business activities in supply chains. The study shows that there is a potential bullwhip effect between companies’ inbound and outbound logistics flows, i.e. two internal stocking levels. A see‐saw model of the bullwhip effect, and a typology of the bullwhip effect in intra‐organisational echelons, are introduced. The term “reversed bullwhip effect” is also introduced. Finally, a model of the bullwhip effect‐scenarios in a dynamic business environment positions these contributions in a wider theoretical and managerial context.

Abstract

Purpose

Collaborative Logistics (CL) and merging operations are crucial strategies for reducing costs and improving service in transportation companies. This study proposes a model for optimizing efficiency in supply chain networks through inbound and outbound Collaborative Logistics implementation among the carriers in centralized, coordinated networks with cross-docking.

Design/methodology/approach

A mixed-integer non-linear programming model is developed to determine the optimal truck-goods assignment while gaining economies of scale through mixing multiple less-than-truckload (LTL) products with different weight-to-volume ratios. Unlike the previous studies that have considered Collaborative Logistics from the cost and profit-sharing perspective, the proposed model seeks to determine an appropriate form of Collaborative Logistics in the VRP.

Findings

This article shows that in a three-echelon supply chain consisting of a set of suppliers, a set of customers and a cross-docking terminal, partial collaboration among the inbound carriers and outbound carriers outperforms no/complete collaboration. This approach enhances the supply chain efficiency by minimizing the total transportation costs, the total transportation miles and the total number of trucks and maximizing fleet utilization. While addressing the four points, the role of collaborative logistics among the carriers was discussed. In a three-echelon SC consisting of a set of suppliers, a set of customers and a cross-docking terminal, partial collaboration among the inbound carriers and outbound carriers outperforms no/complete collaboration. Using a combination of experimental analysis and optimization process, it was recommended that managers be cautious that too much (full or complete) or no collaboration can result in SC performance deterioration.

Originality/value

The suggested approach enhances the supply chain efficiency by minimizing the total transportation costs, the total transportation miles and the total number of trucks and maximizing fleet utilization. While addressing the four points, the role of Collaborative Logistics among the carriers was discussed.

Abstract

The reason for this research originates from the time‐ and functional dependencies between firms’ activities and resources in supply chains. These dependencies cause vulnerability. The principal objective of this research is to conceptualize the construct of vulnerability in firms’ inbound and outbound logistics flows. The vulnerability construct of this research consists of two components: disturbance and the negative consequence of disturbance. This research is based upon a two‐phase process utilizing sequential triangulation. It is proposed that the vulnerability in the inbound logistics flows from sub‐contractors, and the vulnerability in the outbound logistics flows to customers, may be measured and evaluated by four principal dimensions, namely: service level, deviation, consequence and trend. In addition, a model of inbound and outbound vulnerability scenarios in supply chains is introduced for teaching and training purposes, as well as to position and compare the outcome of replication studies of vulnerability in firms’ inbound and outbound logistics flows.
