This study investigates strategies for improving the operational resilience, i.e. an organisation’s capacity to minimise, manage, and recover from disruptions quickly, ensuring continuity in its primary business processes. The focus has been a national infrastructure company, specifically in energy production, and the large supply chain disruptions it has experienced in the wake of COVID-19 and the Ukraine war. The study primarily compares the investigated strategies with literature and theoretical frameworks from a procurement research perspective. The study is an embedded multiple case study investigating three cases with delayed renewal projects. The identified disruptions and their effect on the projects’ performance have been studied, as well as more direct reasons for delays in the cases, such as organisational issues and procurement processes. A framework for categorising disruptions has been developed and three different portfolio purchasing models were investigated in order to be applied to the findings of the study. Key findings reveal that disruptions have affected the case company’s operations significantly, with more projects being delayed and fewer available suppliers in the wake of these disruptive events. Inefficient decision making processes have also been identified as sources of delays, as well as lack of communication within the organisation. The study concludes in practical recommendations for the case company, which can be applicable for similar companies as well. A significant recommendation was that the case company should form strategic partnerships with suppliers of generators, transformers and control systems in order to ensure ample future availability of key components. Other recommendations include working towards more efficient decision making processes when deviating from the group instructions surrounding competitive tendering as well as improving the communication of procurement strategies within the organisation / Denna studie undersöker strategier för att förbättra den operativa motståndskraften, d.v.s. en organisations förmåga att minimera, hantera och återhämta sig snabbt från störningar, för att säkerställa kontinuitet i sina primära affärsprocesser. Fokus har varit på ett nationellt infrastrukturföretag, specifikt inom energiproduktion, och de stora störningar i leveranskedjorna som de har upplevt i kölvattnet av COVID-19 och kriget i Ukraina. De undersökta strategierna kommer att jämföras med litteratur och teoretiska ramverk främst från ett inköpsperspektiv. Studien är en multipel fallstudie inom en organisation som undersöker tre fall med försenade förnyelseprojekt. De identifierade störningarna och deras effekt på projektens prestanda har studerats, liksom mer direkta orsaker till förseningarna i projekten, såsom organisatoriska problem och inköpsprocesser. Ett ramverk för kategorisering av störningar har utvecklats och tre olika portföljinköpsmodeller undersöktes för att kunna tillämpas på studiens resultat. Studien visar att störningarna har påverkat företagets verksamhet avsevärt, med fler försenade projekt och färre tillgängliga leverantörer som följd av av dessa störande händelser. Ineffektiva beslutsprocesser har också identifierats som källor till förseningar, liksom brist på kommunikation inom organisationen. Studien avslutas med praktiska rekommendationer till företaget, som även kan vara tillämpliga för liknande företag. En betydande rekommendation var att företaget bör bilda strategiska partnerskap med leverantörer av generatorer, transformatorer och kontrollanläggningar för att säkerställa framtida tillgång till kritiska komponenter. Andra rekommendationer inkluderar att arbeta mot mer effektiva beslutsprocesser vid avvikelser från koncerninstruktioner om konkurrensutsättning samt förbättra kommunikationen av inköpsstrategier inom organisationen.

Supply chains have become increasingly unstable due to unanticipated disruptive events, which undermines a firm's capacity to achieve a competitive market advantage and increase profitability. The disruption of a supply chain is essential to supply chain managers, as the interruption can be expensive, and the goods and services lost can negatively affect the entire supply chain. The purpose of this qualitative multiple case study was to explore strategies that manufacturing firm managers use to mitigate supply chain disruptions to remain profitable. The population consisted of 4 supply chain managers from 2 manufacturing firms located in the southern region of eastern Virginia. The conceptual framework for this study was the contingency theory of fit. Data were collected from semistructured interviews, company documents, and publicly available information. Based on the thematic data analysis, 3 emergent themes developed as collaboration and information sharing, information technology and supply chain risk, and use of multiple suppliers. The implications for positive social change include potential increased employment opportunities and salaries, investments in community projects, and enhanced consumer spending in the local community, thereby raising the standard of living and social well-being of local community residents.

Background: Reshoring is a growing phenomenon that refers to a company’s decision to move production back from a previously offshored location. There are many drivers and barriers to such decisions that display an increased complexity for managers. It gets even more challenging in a world with high levels of uncertainty shown in the past decade.    Purpose:  This study aims to investigate the drivers and barriers of reshoring and how managers perceive the risk of disruptive events as a driver of reshoring.    Method: This study uses a qualitative method and deductive approach, where empirical evidence was collected through semi-structured interviews with eight managers at clothing companies.   Conclusion: The findings of this study confirm several already established drivers and barriers to reshoring in the particular context of the clothing industry. Furthermore, the study shows that managers perceive an increased willingness to reshore as a response to disruptive events. This was to a large extent due to long lead times and higher coordination costs. Managers can use the findings as support in making decisions of where to locate their production.

This dissertation investigates the consequences of supply chain disruptions in pharmaceutical supply chains. Across different studies, I examine various impacts of pharmaceutical supply chain disruptions on buyer’s behavior, medication errors, and market share. In Chapter 1, coauthored with Anita Carson, Erin Fox, and Rena Conti, we demonstrate the stockpiling behaviors of buyers during the early phase of the COVID-19 pandemic. Leveraging a quasi-experimental design on IQVIA’s National Sales Perspectives™ data, we show that the sales volume of essential medicines related to U.S. hospital-based COVID-19 treatment concentrated only for the first two months of the pandemic. After these two months, the sales volume of drugs for COVID-19 treatment decreases significantly despite a nationwide increase in COVID-19-related hospitalizations. In Chapter 2, coauthored with Anita Carson and Rena Conti, we examine the impact of a hurricane that decimated the factories of major producers of heparin, an important drug used frequently in hospitals. Using a natural experiment, we find that the hurricane-related pharmaceutical supply chain disruption increased medication error rates of heparin. In addition, we find significant spillover effects. The supply chain disruption increased the medication error rates of a substitute drug. In Chapter 3, coauthored with Anita Carson and Rena Conti, we study how long it takes to recover the market share after the supply chain disruptions using a new metric we propose, Time to Recover Market Share. We explore the differential effects by the brand type of products, the competition level in markets, and the duration of the supply disruptions. With the extensive global supply chain disruptions that we are facing today, understanding their potential consequences is significant. This dissertation advances our understanding of the different impacts of supply chain disruptions and provides practical implications for supply chain members to build resilient supply chains and minimize the effects of supply chain disruptions.

This dissertation consists of three papers related to firms' resiliency to supply chain disruptions. The first paper seeks to evaluate the effects of supply chain disruptions on firms' performance by using a recent dataset of supply chain disruptions. To this end, we analyzed operating and stock market performances of over 300 firms that experienced a supply chain disruption during 2005 to the end of 2014. The results show that supply chain disruptions are still associated with a significant decrease in operating income, return on sales, return on assets, sales, and a negative performance in total assets. Supply chain disruptions are also associated with a significant negative abnormal stock return on the day of the supply chain disruption announcements. These results are in line with previous findings in the literature. In the second paper, in order to provide a more detailed characterization of negative impacts of disruptions on firms' performance, we develop three complementary measures of system loss: the initial loss due to the disruption, the maximum loss, and the total loss over time. Then, we utilize the contingent resource-based view to evaluate the moderating effects of operational slack and operational scope on the relationship between the severity of supply chain disruptions and the three complementary measures of system loss. We find that maintaining certain aspects of operational slack and broadening business scope can affect these different measures of loss in different ways, although these effects are contingent on the disruptions' severity. The third paper examines relationships between the origin of supply chain disruptions, firms' past experience, and the negative impacts of supply chain disruptions on firms' performance. This third study shows that the impact of external and internal supply chain disruptions on firms' performance can be different when firms do and do not have past experience with similar events. For example, the results show that past experience significantly decreases initial loss, recovery time, and total loss over time experienced by firms after internal disruptions, although past experience may not decrease initial loss, recovery time, and total loss over time in the case of external disruptions. / Ph.

Yes / Purpose Medicine shortages have a detrimental impact on stakeholders in the pharmaceutical supply chain (PSC). Existing studies suggest that building resilience strategies can mitigate the effects of these shortages. As such, this research aims to examine whether resilience strategies can reduce the impact of medicine shortages in the United Kingdom's (UK) PSC. Design/methodology/approach A sequential mixed-methods approach that involved qualitative and quantitative research enquiry was employed in this study. The data were collected using semi-structured interviews with 23 key UK PSC actors at the qualitative stage. During the quantitative phase, 106 respondents completed the survey questionnaires. The data were analysed using partial least square-structural equation modelling (PLS-SEM). Findings The results revealed that reactive and proactive elements of resilience strategies helped tackle medicine shortages. Reactive strategies increased relational issues such as behavioural uncertainty, whilst proactive strategies mitigated them. Practical implications The findings suggest that PSC managers and decision-makers can benefit from adopting structural flexibility and proactive strategies, which are cost-effective measures to tackle medicine shortages. Also engaging in strategic alliances as a proactive strategy mitigates relational issues that may arise in a complex supply chain (SC). Originality/value This study is the first to provide empirical evidence of the impact of resilience strategies in mitigating medicine shortages in the UK's PSC.

Independent de la performance remarquable accomplie par la logistique d’aujourd’hui, les réseaux actuels sont majoritairement dédiés à un acteur et donc très peu interconnectés. Cette fragmentation conduit une difficulté de mutualisation des flux et dès lors à une efficacité limitée. Ces organisations dédiées et hétérogènes sont de plus en plus challengées par les nouveaux défis d’aujourd’hui posés à l’efficacité, l’efficience et la résilience. Pour répondre à cet antagonisme, un innovant concept logistique - l’Internet Physique (PI) - a été proposé. Dans ce système, les infrastructures et les moyens de transport peuvent être organisés de façon dynamique et attribués à court ou à long terme en fonction des besoins. Par conséquent, les décisions des opérations logistiques peuvent être prises de façon dynamique, agile, et donc de manière plus optimale. Cette thèse concentre les perspectives de PI concernant la gestion de stocks et du transport par rapport aux défis de l’efficacité et de la résilience.Comme l’étude de l’efficacité de PI par rapport au transport a été déjà effectuée, le premier objectif de cette recherche est d’explorer les potentiels de l’interconnexion des réseaux dans la gestion de stocks, qui n’a par encore été adressé. À cette fin, nous examinons d'abord les trois nouvelles pratiques apportées par PI : 1) les stocks distribués à proximité des clients finaux; 2) le transbordement de stocks entre les hubs; 3) de multiples options dynamiques de sélection de la source pour chaque commande. Deux modèles de gestion de stocks correspondants sont proposés. Cette étude sert de guide pour des décisions de stockage pour les vendeurs dans un tel système logistique ouvert.Après l’analyse d’efficacité de PI, la deuxième partie de cette thèse concerne la résilience des modèles de stockage et de transport dans PI confrontés à des interruptions dans la chaîne logistique. On a étendu les modèles de stockage et de transport avec interruptions imprévisibles dans les infrastructures telles que l’usine ou les hubs. Des stratégies différentes sont développées pour atténuer les risques de perturbation des flux. Des études numériques sont effectuées pour évaluer la performance des modèles proposés.En résumé, cette recherche est la première qui étudie le potentiel de l’Internet Physique pour la gestion de stock et la résilience de ce système. D’après les résultats, il n’y a aucun doute que le PI change le design de chaîne logistique d’aujourd’hui et améliore la performance de gestion de logistique à la fois en efficience et en résilience. / Irrespective of significant performance achieved, today’s logistics networks are overwhelmingly dedicated to an actor and therefore poorly interconnected. This fragmentation exhibits inevitable inefficiency and needs to be changed in respond to today’s new arising challenges in efficiency and resilience. To solve this antagonism, an innovative concept - Physical Internet (PI) - has been proposed which is a fully interconnected, open, dynamic logistics system. In such a system, the facilities and means of transportation can be dynamically organized and allocated in the short-term or long-term according to the economic environment. As a result, decisions can be made dynamically, agilely, and thus optimally. This thesis studies the perspectives of the PI to inventory management and transportation regarding the challenges in efficiency and resilience.As the efficiency of the PI to transportation has been carried out in literature, the first objective of this thesis is to explore the potentials of the PI to inventory management. To this end, we firstly qualitatively examine the new practices brought by the PI and conclude three main characteristics: 1) Distributed stocks near end customers; 2) Transshipment of inventories; and 3) multiple dynamic source options. Corresponding inventory models and solutions are proposed and evaluated with numerical experiments in Fast Moving Consumer Goods (FMCG). This part of study gives a guideline for the vendors applying the PI to make inventory decisions in such an open logistic system.The second objective is to analyze the resilience of the proposed PI enabled inventory and transportation model confronted to disruptions. The proposed inventory and transportation model are extended with different disruptions at facilities including plants and hubs. Different disruption strategies are developed. Numerical studies in FMCG are carried out.In a word, this research investigates the inventory management in the PI and the resilience of PI enabled logistics models. It is the first time such a work is done and it should be upfront. From the results of studies, there is no doubt that the PI changes today’s supply chains design and improve the performance of supply chain management both in efficiency, effectiveness and resilience.

The world is changing, what has been known to work has been put to the test when both the geopolitical and the environmental climate are changing. War, a pandemic, material shortage, financial difficulties and an overall dis- tressed global transportation sector have shown that the ever-more important topic of resilience is crucial to stay relevant in today’s competitive markets. Companies are therefore switching focus towards ensuring sufficient supply chain resilience capabilities to handle these ever-changing situations on the global market.  In this thesis, we focus on how Volvo SML is working with resilience today, and how graph theory and optimisation can be useful tools when analysing a supply chain’s resilience. We made a qualitative analysis by conducting inter- views with employees and comparing our findings with capabilities related to resilience. In addition, we conducted a quantitative analysis by constructing a simulation of the supply chain, comparing two topology metrics and two op- timisation metrics, to analyse the robustness of the aftermarket supply chain.  We analysed the data and summarised the insights gathered from the inter- views using a resilience capability framework. Volvo SML proved to be agile and reactive when dealing with disruptions but is missing some key capabil- ities during the pre-and post-disruption phases. Some areas of improvement we identified were: robustness, collaboration and redundancy. We proved that the simulation is useful when evaluating the robustness of a supply chain, and we showed that a more flexible way of working would improve the overall robustness of Volvo SML’s aftermarket supply chain.
