Abstract [en]

Purpose: When faced with severe crises or war, Swedish authorities need to adaptively secure supply of critical components for their operations. They are in this dependent on industry’s production system and supply chain (SC) network. When critical shortages occur, alternatives need to be investigated and developed quickly. This paper aims to present a methodology and way of work to review SC alternatives and developing solutions when an acute shortage is at hand. Design/methodology/approach: The paper presents action-research based work, performed within a project developing resilient SC-management. An iterative scenario workshop approach was applied to develop and test the methodology. The workshops were performed in a simulated crisis-situation setting. Participating authorities oversaw infrastructural functions and a simulated component shortage, while a cross functional team of researchers and experts applied the methods to find solutions to the situation. The workshop goal was to find and develop several parallel solutions to each shortage situation. Between workshops, literature search, discussion and trials with practitioners, and cross functional process development was done. Findings: The findings resulted in a guideline for the process from identifying a need to initiating parallel solutions to resolve a shortage. Available materials, production techniques, and critical product-specific characteristics were identified and investigated within the workshops. The solutions were based on four main redesign concepts: •Re-sourcing/Sourcing of equivalent product(s) •Reuse via washing/repair/recycling •Reverse engineering - copying existing product •Product development - developing a new product Research limitations: The conducted workshops were designed with predefined specific conditions, such as national localization for solution application, logistical challenges, and import restrictions. Practical, managerial and societal implications: The research was part of a larger research project where the aim was to support Swedish authorities in their development of resilience and security of supply. Both practical results and methodological development of how to perform supply chain scenario workshop simulations will be used by authorities. Original/value: There exist several studies on how to proactively redesign supply chains to be more resilient, but less papers focus on how to redesign the supply when shortage occurs in crisis situations. This paper contributes with empirical research on such situations. Keywords: Emergency supply, Scenario workshop simulation, Action research, Supply chain resiliens

Abstract [sv]

Rapporten är resultatet av en studie som genomförts av RISE på uppdrag av Fortifikationsverket och MSB. Studien syftade till att stärka Sveriges förmåga till inhemsk produktion av kritiska produkter och komponenter vid kriser och höjd beredskap. Bakgrunden till projektet är det försämrade säkerhetsläget och erfarenheter från coronapandemin som visade på sårbarheter i globala leveranskedjor. Rapporten presenterar en strukturerad metod för produktionsomställning vid försörjningsbrister, där samverkan mellan myndigheter och näringsliv är central. Fokus ligger på alternativ produktion, snarare än traditionell lagerhållning, för att säkerställa tillgången på skyddsprodukter och reservdelar till samhällsviktig infrastruktur. Viktiga delar i processen är kartläggning av kritiska produkter, försörjningskedjor och svensk produktionskapacitet, samt utveckling av försörjningsstrategier som inkluderar återbruk och alternativa material. En tydlig metodik för nödproduktion redovisas, där målbild, kravspecifikation och produktionskapacitet analyseras systematiskt. Slutligen betonas vikten av säkerhetsskydd, scenarioplanering och samordnad styrning för att snabbt kunna skala upp produktion vid kriser. Rapporten är ett bidrag och verktyg för fortsatt utveckling av Sveriges försörjningsberedskap.

Abstract [sv]

Projektet har studerat sårbarheter i försörjningen av kritiska material och produkter vid kris eller konflikt, men också möjligheter till stärkt nationell resiliens. Genom fallstudier och systemanalys har projektet undersökt hur Sverige kan öka sin förmåga att snabbt ställa om och säkra tillgången till viktiga komponenter inom vård, skyddsutrustning och elektronik.Projektet har fokuserat på följande materialområden: plast, metall och elektronik. Plast är till stor del fossilbaserad och har låg återvinningsgrad, metaller kräver ofta importerade legeringsämnen trots goda inhemska resurser och dagens elektronikproduktion är starkt globaliserad med låg självförsörjningsgrad. Samtidigt finns betydande inhemsk kapacitet inom flera områden –exempelvis plastformulering, metallbearbetning och elektronikmontering – som kan mobiliseras vid behov.Fallstudier på medicintekniska produkter visade att additiv tillverkning (3D-printing) kan bidra till snabb omställning men har begränsningar i materialval och produktionsvolym. För formsprutning, som traditionellt har längre ledtider, kan dessa reduceras kraftigt genom effektiv samverkan och parallella arbetsmoment. En ny produkt designades, verifierades och producerades inom 60 timmar – ett tydligt exempel på hur svensk industri kan agera snabbt vid behov.För munskydd klass IIR genomfördes nödproduktion med testning enligt gällande standarder. Nationell kapacitet finns för vissa non-woven-material, medan man för andra är beroende av import. En mobil produktionslinje testades och utvärderades genom sårbarhetsanalys, vilket visade att även små enheter kan bidra till märkbart ökad resiliens.Inom elektronikområdet identifierades flera utmaningar. Fallstudien på växelriktare visade att återtillverkning och reparation är möjligt med rätt kompetens och tillgång till komponenter. Många delar kan återanvändas från konsumentelektronik, men avancerade halvledarkomponenter kräver import. Inhemsk kapacitet finns för mönsterkort, transformatorer och montering, vilket ger goda förutsättningar för decentraliserad produktion.Rapporten presenterar även metoder för att utvärdera resiliens – både kvalitativt och kvantitativt – där samspelet mellan teknik, organisation och kompetens är avgörande. Genom att identifiera svaga länkar, bygga redundans och träna personal kan svensk försörjningsförmåga stärkas. Slutsatsen är tydlig: Sverige har kapacitet och kapabilitet att bygga ett mer motståndskraftigt system, men kräver strategiska investeringar och samordning.

Abstract [en]

Efficient, simple antibacterial materials to combat implant-associated infections are much in demand. Herein, the development of polyurethanes, both cross-linked thermoset and flexible and versatile thermoplastic, suitable for “click on demand” attachment of antibacterial compounds enabled via incorporation of an alkyne-containing diol monomer in the polymer backbone, is described. By employing different polyolic polytetrahydrofurans, isocyanates, and chain extenders, a robust and flexible material comparable to commercial thermoplastic polyurethane is prepared. A series of short synthetic antimicrobial peptides are designed, synthesized, and covalently attached in a single coupling step to generate a homogenous coating. The lead material is shown to be biocompatible and does not display any toxicity against either mouse fibroblasts or reconstructed human epidermis according to ISO and OECD guidelines. The repelling performance of the peptide-coated materials is illustrated against colonization and biofilm formation by Staphylococcus aureus and Staphylococcus epidermidis on coated plastic films and finally, on coated commercial central venous catheters employing LIVE/DEAD staining, confocal laser scanning microscopy, and bacterial counts. This study presents the successful development of a versatile and scalable polyurethane with the potential for use in the medical field to reduce the impact of bacterial biofilms.

Abstract [en]

The use of adhesives for fracture fixation can revolutionize the surgical procedures toward more personalized bone repairs. However, there are still no commercially available adhesive solutions mainly due to the lack of biocompatibility, poor adhesive strength, or inadequate fixation protocols. Here, a surgically realizable adhesive system capitalizing on visible light thiol–ene coupling chemistry is presented. The adhesives are carefully designed and formulated from a novel class of chemical constituents influenced by dental resin composites and self-etch primers. Validation of the adhesive strength is conducted on wet bone substrates and accomplished via fiber-reinforced adhesive patch (FRAP) methodology. The results unravel, for the first time, on the promise of a thiol–ene adhesive with an unprecedented shear bond strength of 9.0 MPa and that surpasses, by 55%, the commercially available acrylate dental adhesive system Clearfil SE Bond of 5.8 MPa. Preclinical validation of FRAPs on rat femur fracture models details good adhesion to the bone throughout the healing process, and are found biocompatible not giving rise to any inflammatory response. Remarkably, the FRAPs are found to withstand loads up to 70 N for 1000 cycles on porcine metacarpal fractures outperforming clinically used K-wires and match metal plates and screw implants.

Abstract [en]

Nanometer scale surface features on implants and prostheses can potentially be used to enhance osseointegration and may also add further functionalities, such as infection resistance, to the implant. In this study, a nanostructured noble metal coating consisting of palladium, gold and silver, never previously used in bone applications, was applied to machined titanium screws to evaluate osseointegration after 6 and 12. weeks in rabbit tibiae and femurs. Infection resistance was confirmed by in vitro adhesion test. A qualitatively and quantitatively similar in vivo bone response was observed for the coated and uncoated control screws, using histology, histomorphometry and electron microscopy. The bone-implant interface analysis revealed an extensive bone formation and direct bone-implant contact. These results demonstrate that the nanostructured noble metal coating with antimicrobial properties promotes osseointegration and may therefore be used to add extra implant functionality in the form of increased resistance to infection without the use of antibiotics. From the Clinical Editor: The authors of this paper demonstrate that nanostructured noble metal coating of implants and prostheses used in orthopedic procedures promotes osseointegration and may be used to add extra implant functionality in the form of increased resistance to infection without the use of antibiotics.
