Indiana University-Purdue University Indianapolis (IUPUI) / Affordable and reliable supply chain visibility is becoming increasingly important as the complexity of the network underlying supply chains is becoming orders of magnitudes higher compared to a decade ago. Moreover, this increase in complexity is starting to reflect on the cost of goods and their availability to the consumers. Optimizing the physical distribution phase in supply chain by providing increased visibility to trading partners can directly reduce product cost. Current supply chain information systems often lack the ability to cost-effectively relay ground truth in- formation in near real time to all stakeholders and most importantly to the supplier and the customer during the transport of the shipment. This thesis presents a solu- tion that addresses this gap through a distributed architecture. The solution enables small, medium and large businesses to interact in a dynamic and shipment-centric manner through a private blockchain sub-ledger that digitizes the transfer of custody for each shipment. Information in this private ledger is augmented by a public event ledger that reflects the movement of the shipment in real time. Third party monitors are engaged in the validation of the geolocation of the shipments by posting their physical proximity in the form of events to the public ledger.

<p> This thesis summarizes theoretical results of two projects on the investigation of a novel organometallic polymer, the polyferrocenylsilanes(PFS). The study is carried out in collaboration with the experimental groups of Prof. Manners and Prof. Winnik at the Department of Chemistry of University of Toronto. </p> <p> In the first project, a rotational isomeric state (RIS) model is applied to study the configurational statistics of an ideal polyferrocenyldimethylsilane (PFDMS) chain: Fc[Fe(C5H4)2SiMe2]nH (Fe= Fe(C5H5)(C5H4)). The necessary conformation energies are derived from the molecular mechanics study of oligomeric (n=1,2) models for PFDMS reported by O'Hare et al.(J. Am. Chem. Soc. 1996, 118, 7578). In particular, pseudoatom and pseudobonds are introduced to describe the RIS chain of PFDMS, consistent with the special molecular geometry of the repeating ferrocene and organosilane units. The mean square unperturbed dimensions ((r^2)0, (R^2g)0), the characteristic ratios Cn(C∞) and the temperature coefficients dln (r^2)0/dT of PFDMS are calculated. The results show that an ideal PFDMS chain has a relatively low value of Coo and fast convergence of Cn to C∞ with increasing n, indicating a high static flexibility of this type of transition metal-containing polymer. The previously unknown Kuhn length of PFDMS is obtained based on the calculated C∞ </p> <p> In the second project, by taking PFS-b-PDMS/alkane as a model system, general phase behaviours of the self-assembled micelles in dilute crystalline-coil copolymer solutions (solvents are selective for the coil blocks) are investigated. Three types of aggregates - lamellar, rodlike and tubular micelles are studied based on the existing experimental observations. The computation results reveal three types of phase diagrams, namely, lamella-tube-rod phase diagrams with or without a triple point and lamella-rod phase diagrams. It is shown that lamella-tube-rod morphological transitions can be induced by changing the coil/crystalline block ratio or the temperature. Possible improvement of the theory and the current challenges of studying PFS-b-PDMS self-assembly in alkane solvents for both theories and experiments are discussed. </p> / Thesis / Master of Science (MSc)

Supply chains are complex systems. Researchers in the Social and Decision Analytics Laboratory (SDAL) at Virginia Tech worked with a major global supply chain company to simulate an end-to-end supply chain. The supply chain data includes raw materials, production lines, inventory, customer orders, and shipments. Including contributions of this author, Pires, Sabin, Higdon et al. (2017) developed simulations for the production, customer orders, and shipments. Customer orders are at the center of understanding behavior in a supply chain. This dissertation continues the supply chain simulation work by improving the order simulation. Orders come from a diverse set of customers with different habits. These habits can differ when it comes to which products they order, how often they order, how spaced out those orders times are, and how much of each of those products are ordered. This dissertation is unique in that it relies extensively on Dirichlet and multiscale methods to tackle supply-chain order simulation. Multiscale model methodology is furthered to include Dirichlet models which are used to simulate order times for each customer and the collective system on different scales. / Doctor of Philosophy / This dissertation continues the supply chain simulation work of researchers (Pires et al. (2017)) in the Social and Decision Analytics Laboratory (SDAL) at Virginia Tech by improving the order simulation. Orders come from a diverse set of customers with different habits. These habits can di er when it comes to which products they order, how often they order, how spaced out those orders times are, and how much of each of those products are ordered. This dissertation is unique from the previous work at SDAL which considered few of these factors in order simulation and introduces statistical methodologies to deal with the complex nature of simulating an entire supply chain's orders.

Yes / The effective management of pharmaceuticals in the National Health Service (NHS) is critical to patient welfare thus any risks attached to this must be identified and controlled. At a very basic level, risks in the pharmaceutical supply chain are associated with product discontinuity, product shortages, poor performance, patient safety/dispensing errors, and technological errors (causing stock shortages in pharmacies) to name but a few, all of which incur risk through disruption to the system. Current indications suggest that the pharmaceutical industry and NHS practitioners alike have their concerns as to the use of generic supply chain strategies in association with what is perceived to be a specialist product (pharmaceuticals). The aim of the study undertaken was to gain a more realistic understanding of the nature and prevalence of risk in the Pharmaceutical Supply Chain (PSC) to be used as a basis for a more rigorous research project incorporating in-vestigation in the UK, Europe and USA. Data was collected via a workshop forum held in November 2005. The outputs of the workshop indicated that there were thirty-five prevalent risks. The risks were rated using risk assessment catego-ries such as impact, occurrence and controllability. The findings indicated that the risks identified are similar to those prevalent in industrial supply chains, regardless of the idiosyncrasies of pharmaceuticals. However, the group consen-sus was that caution must be applied in how such risks are addressed, as there are aspects of the product that highlight its uniqueness e.g. criticality.

This dissertation focuses on understanding the impact of systems thinking on supply chain management. The first essay presents a systematic literature review, examining the current state of systems thinking research within the context of supply chain management. It explores the similarities and differences in various studies, identifies research gaps, and outlines future opportunities in the field. The second essay investigates the current state of systems thinking in individuals working in supply chains at different stages of their careers. This is achieved through the use of a specially created game called the systems thinking game. The game is designed to assess and enhance systems thinking skills among supply chain professionals. The findings from this study provide valuable insights into the effectiveness of interactive learning tools in developing systems thinking abilities and suggest ways to incorporate these tools into professional development programs. The third essay explores the holistic management of supply chain complexity, emphasizing its critical impact on business performance, including lead times, costs, and operational efficiencies. It highlights the importance of a comprehensive approach to foster innovation and adaptability in response to rapid market changes and technological advancements. By addressing detail and dynamic complexities and leveraging advanced information systems, the essay demonstrates how holistic management and technical skills can enhance decision-making processes, leading to improved supply chain performance and resilience. Overall, this dissertation aims to bridge the gap between theoretical frameworks and practical applications of systems thinking in supply chain management, providing a holistic approach to understanding and managing supply chain complexities.

O estudo consiste em analisar as diferenças do supply chain de moda entre as coleções tradicionais e o fast fashion, identificando os desafios e ações empreendidas pelas empresas têxteis que atuam no início da cadeia produtiva de moda. Tomando como base a literatura sobre as gestões da cadeia produtiva de moda e as mudanças ocorridas no mercado, identificou-se a contradição no tempo de aprovisionamento no que diz respeito às etapas de produção entre a moda tradicional e o fast fashion, termo em inglês, traduzido como moda rápida. As análises e comparações entre as gestões da cadeia produtiva de moda compreendem como esses dois sistemas atuam no mercado. Por um lado, existem as empresas de moda programada tradicional que pelo conceito e o tempo utilizado para o desenvolvimento de suas coleções funcionam como uma forma de imposição do consumo de seus produtos, já o modelo fast fashion pode ser interpretado como uma resposta do mercado consumidor. Com isso, a necessidade de diminuir o time to market para reduzir o risco exige encontrar soluções produtivas adequadas. A partir de uma revisão de literatura e de uma pesquisa exploratória, foi possível identificar como o setor têxtil, que atua no início da cadeia produtiva de moda, corresponde às diferenças de supply chain entre as coleções tradicionais e o fast fashion / This study consists on analyzing the supply chain differences between the traditional collections and the fast fashion, identifying the challenges and the undertaken actions by textile companies that act in the beginning of fashion productive chain. Taking as a base the literature on fashion productive chain management and the market changes, the contradiction on provision time was identified about the production levels between the traditional fashion and the fast fashion. The analysis and comparisons between fashion productive chain management comprehend on how theses both methods act on market. On the one hand there are the scheduled traditional fashion companies that through conception and the used time to develop their collection, it works as imposition consumption for their products, whereas the fast fashion way can be seen as the customer reply. Therewith, there is a need to reduce the time to market to decrease the risk new productive solutions must be found. From a literature review and a deep research, it was possible to identify how the textile sector, which operates at the beginning of the production chain fashion, corresponds to the supply chain differences between traditional collections and the fast fashion
