Abstract

Purpose

Disruptions at ports may destroy the planned ship schedules profoundly, which is an imperative operation problem that shipping companies need to overcome. This paper attempts to help shipping companies cope with port disruptions through recovery scheduling.

Design/methodology/approach

This paper studies the ship coping strategies for the port disruptions caused by severe weather. A novel mixed-integer nonlinear programming model is proposed to solve the ship schedule recovery problem (SSRP). A distributionally robust mean conditional value-at-risk (CVaR) optimization model was constructed to handle the SSRP with port disruption uncertainties, for which we derive tractable counterparts under the polyhedral ambiguity sets.

Findings

The results show that the size of ambiguity set, confidence level and risk-aversion parameter can significantly affect the optimal values, decision-makers should choose a reasonable parameter combination. Besides, sailing speed adjustment and handling rate adjustment are effective strategies in SSRP but may not be sufficient to recover the schedule; therefore, port skipping and swapping are necessary when multiple or longer disruptions occur at ports.

Originality/value

Since the port disruption is difficult to forecast, we attempt to take the uncertainties into account to achieve more meaningful results. To the best of our knowledge, there is barely a research study focusing on the uncertain port disruptions in the SSRP. Moreover, this is the first paper that applies distributionally robust optimization (DRO) to deal with uncertain port disruptions through the equivalent counterpart of DRO with polyhedral ambiguity set, in which a robust mean-CVaR optimization formulation is adopted as the objective function for a trade-off between the expected total costs and the risk.

Abstract

Purpose

This paper provides evidence based quantification of both “actual” disruption of industries as well as a measure of disruption “hype”. The data cover a seven-year period from 2012 to 2018 across 12 industries. The authors’ complemented the research with a survey of 2000 business executives. Whereas there has been some measures of disruption in the past, no research to the authors’ knowledge has been conducted that measure both actual disruption and disruption hype.

Design/methodology/approach

The current fascination with disruption hides an awkward truth, we assume it is happening, but do we really know for sure? Disruption is rarely defined and almost never measured. Equally, the influence of the hype around disruption is hard to gauge. The authors do not know to what extent hype is driving management action. This is worrisome as the disruption “noise level” can lead to unhealthy collective thinking and bad business decision-making. Some rigour is required. To craft winning strategies, executives should take a more evidence-based approach for managing disruption.

Findings

The authors’ failed to find evidence of any correlation between the hype around an industry disruption and actual disruption within that industry. So the important conclusion for executives is “do not believe the hype”. We found some surprising differences by industry between actual disruption and the hype by industry.

Research limitations/implications

Disruption is one of the most talked about subject in the field of strategy, yet there is little quantification. With this research, the authors’ aim is to advance the fact-based understanding of disruption. Disruption hype is never measured but has a strong influence on executives. The authors have quantified hype using online, search, social media and survey sources. Much more is needed to be able to measure hype more accurately.

Practical implications

The authors’ recommend a set of practical guidelines for executives to support fact-based strategy formulation: analysis of actual disruption, scenario planning and strategic responses.

Social implications

The “noise” around industry disruption is so high that it is assumed to happen. Much of what is written is quasi-fake news. The authors need to rebalance the debate with fact-based analysis.

Originality/value

To authors’ knowledge, there has never been any fact-based analysis of both actual and hype disruption levels.

Abstract

Purpose

Severe disruptions to maritime supply chains, including port closures, congestion and shortages in shipping capacity, have occurred during the COVID-19 pandemic. This paper’s purpose is to explore flexibility-based countermeasures that enable actors in maritime supply chains to mitigate the effects of disruptions with different characteristics.

Design/methodology/approach

Semi-structured interviews were conducted with shipping lines, shippers, forwarders and ports. Data on the COVID-19 pandemic's effects and countermeasures were collected and compared with data regarding the 2016–2017 Gothenburg port conflict.

Findings

Spatial, capacity, service and temporal flexibility emerged as the primary countermeasures, whilst important characteristics of disruptions were geographical spread, duration, uncertainty, criticality, the element of surprise and intensity. Spatial flexibility was exercised in both disruptions by switching to alternative ports. During the COVID-19 pandemic, ensuring capacity flexibility included first removing and then adding vessels. Shipping lines exercising service flexibility prioritised certain cargo, which made the spot market uncertain and reduced flexibility for forwarders, importers and exporters that changed carriers or traffic modes. Experience with disruptions meant less surprise and better preparation for spatial flexibility.

Practical implications

Understanding how actors in maritime supply chains exercise flexibility-based countermeasures amid disruptions with different characteristics can support preparedness for coming disruptions.

Originality/value

Comparing flexibility-based measures in a pandemic versus port conflict provides insights into the important characteristics of disruptions and the relevance of mitigation strategies. The resilience of maritime supply chains, although underexamined compared with manufacturing supply chains, is essential for maintaining global supply chain flows.

Abstract

Purpose

The purpose is to replicate and extend Ambulkar et al.’s (2015) work testing resource reconfiguration as a mediator of the supply chain disruption/firm resilience relationship and testing risk management infrastructure as a moderator. This study extends the work of Ambulkar in that it uses analysis of survey data gathered from manufacturing firms during an actual disruption event (COVID-19). The previous work is also in extended in that the authors include a pandemic disruption impact variable and supply chain performance is an expanded model.

Design/methodology/approach

Partial least squares structural equation modeling techniques were used to analyze data gathered from 184 US manufacturing managers during the height (Summer 2021) of the COVID-19 pandemic.

Findings

Two of four of Ambulkars et al.’s (2015) hypotheses were confirmed as relevant to firm resilience during the pandemic while two were not confirmed. Results also show that supply chain disruption orientation, risk management infrastructure and resource reconfiguration combine to improve firm resilience, which in turn improves supply chain performance while mitigating the disruption impact of COVID-19.

Originality/value

Previous work is replicated and extended, using data from an actual disruption event (COVID-19). This study presents a more comprehensive model using a newly developed and validated scale to measure pandemic impact and including supply chain performance.

Abstract

Purpose

While, supply chain resilience (SCRES) continues to be a dominant topic in both academic and business literature and has gained more attention recently, there is limited knowledge on SCRES capabilities specific to business functions. The purpose of this paper is to identify and investigate capabilities shared between supply, operations and logistics that are most important for SCRES.

Design/methodology/approach

To address this gap, the authors followed a multi-method research approach. First, the authors used the grounded theory method to generate a theoretical framework based on interviews with 51 managers from five companies in automotive SCs. Next, the authors empirically validated the framework using a survey of 340 SC professionals from the manufacturing industry.

Findings

Five significant capabilities emerged from the qualitative study; all were significant in empirical validation. This research advances the knowledge of SCRES as it informs managerial decision-making by identifying capabilities common to supply, logistics and operations that impact SCRES.

Originality/value

This research advances the knowledge of SCRES as it informs managerial decision-making by identifying capabilities common to supply, logistics and operations that impact SCRES. In addition, the findings of this research help managers better allocate resources among significant capabilities.

Abstract

Purpose

The present manuscript assesses how firms should manage frequent supply chain disruption triggers and whether these firms should use existing supply chain competencies, develop new ones or both to mitigate any adverse consequences on financial performance.

Design/methodology/approach

Data for the study come from a survey administered to professionals in India. India was an appropriate base for the study because of its developing economy and businesses often facing SC disruptions in the marketplace.

Findings

The findings show that the negative association between the frequency of supply chain disruption triggers and financial performance is weaker when a firm utilizes supply chain exploitation competencies. Conversely, the negative association between the frequency of supply chain disruption triggers and financial performance becomes stronger when using supply chain exploration competencies. Most significantly, however, the authors show that a strategy of supply chain ambidexterity – one that combines both exploitation and exploration practices – is more beneficial in mitigating the impact of frequent disruption triggers on firm financial performance compared to the other strategies.

Originality/value

These findings contribute to the literature, extending the benefits of ambidexterity beyond domains of innovation, manufacturing flexibility, competitiveness and firm performance to include mitigation of supply chain disruptions.

Abstract

Purpose

This paper aims to formally conceptualize service mega-disruptions as any far-reaching and unforeseen general environmental stressor or threat that impacts a service organization’s ability to provide a desired level of service. The authors differentiate sudden large-scale general environmental threats from traditional service failures in scope and scale of impact via number of customers and sectors affected and duration and speed of the disruption.

Design/methodology/approach

This paper draws from service recovery theory to build a conceptual model of service mega-disruptions. The resulting conceptual model maps service failure recovery strategies against a service mega-disruption recovery approach to examine consumer response to changes in service value. This work further articulates additional research needs including conceptualization, measurement and methods as traditional drivers of service recovery and the value of the service experience change in response to service mega-disruptions.

Findings

This work proposes a research agenda to investigate whether service mega-disruptions can bypass the need for service recovery due to a consumer self-moderating process. As past research shows, the less control a service provider has over a failure, the more customers attribute fault to the situation and transfer blame away from an organization. This paper suggests that this self-moderating process disrupts the need for service providers to court forgiveness for a failure with perceptions of similarity and controllability providing an alternate pathway to customer forgiveness. Similarly, it is suggested that service mega-disruptions play a role in transforming service ecosystems into tighter, more contractual systems with less agency for service providers and poorer ability to adjust to market conditions. The duration and longevity of effects on service providers’ control, agency and ability to adjust following a service mega-disruption must be researched further.

Originality/value

This paper builds theory to develop a conceptual model of service mega-disruptions and their role in customer engagement and reshaping the service ecosystem. This paper culminates in the proposition of a research agenda that aims to build research capacity among services marketing scholars as service providers’ coordination and market conditions are challenged by service mega-disruptions.

Abstract

Supply chain is an important aspect for all the companies and can affect many aspects of companies. Especially the disruption in supply chain is causing huge impacts and consequences that are difficult to deal with. This chapter presents a review of selected multiple criteria problems used in supply chain optimization. Research analyzed the multiple criteria decision-making methods to tackle the problem of supplier evaluation and selection. It also focuses on the problem of supply chain when a disruption happens and presents strategies to deal with the issue of disruptions in supply chain and how to mitigate the impact of disruptions. Prevention, response, protection, and recovery strategies are explained. Practical part is focused in the risk-averse models to minimize expected worst-case scenario by single sourcing. Computational experiments for practical examples have been solved using CPLEX solver.
