Full textAbstract:
Environmental sustainability has received considerable attention in industry and academia. Many firms have begun to adopt sustainability practices, such as investing in cleaner technology and using organic or recyclable materials, to enhance sustainability in supply chains. Such sustainability practices affect corporate social responsibility and business performance. On the other hand, when consumers and supply chain managers make decisions, they may be constrained by behavioral concerns. Behavioral concerns can significantly influence optimization in supply chains. Thus, it is critical to consider the impacts of behavioral concerns on sustainability in supply chains. In this paper, we concisely examine studies in sustainability issues in supply chains with behavioral concerns and introduce the papers featured in this Special Issue.

Abstract Logistics and supply chain management is a comparatively new scientific field which has been rapidly developing. Apart from the criterion of total logistics costs, that is used to evaluate the efficiency of supply chains, another criterion - total satisfaction of consumer needs - is being increasingly used for the same purpose. It can be explained by the transition to such new logistics concept as the sustainability of supply chains, which is characterized not only by flexibility, rate of response, strength, adaptability, but mostly by the reliability of functioning of the logistics system's elements. The paper presents critical analysis of the existing approaches to the formation of failure models in supply chains, the methodical approach and classification of failures for the key logistics functions (purchasing, order processing, transportation, storage, warehousing and materials handling) as well as some developed and improved failure models for a number of logistics functions and operations; there have been also given some examples of calculating the reliability indices for the elements of the supply chain.

Full textAbstract:
Global manufacturing firms are engaging distant suppliers of critical raw materials to participate in responsible sourcing. Downstream firms are concerned about risks in mineral supply chains of violent conflict, human rights violations, and poor governance, but they are limited in seeing their suppliers. Descriptive data on 323 smelters and refiners of tantalum, tin, tungsten, and gold (the “conflict minerals”) were complemented by interviews with downstream firms in the electronics industry. Results provided a narrative of supplier engagement, describing tactics used to identify “deep suppliers” at chokepoints in metals supply and to persuade producers into joining due diligence programs. Top-tier firms collaborate through a standards program to overcame barriers of geography and cultural distance in supply chain management beyond the visible horizon. Curiously, manufacturers do not need line-of-sight transparency to lower-tier suppliers. Rather, top-tier firms are “jumping the chain” to engage directly with “deep suppliers” who may—or may not—be their own actual physical suppliers. The research contributes empirical evidence to understanding multi-tier supply chains, examines how power is exercised by top-tier firms managing suppliers, and provides insights on supply chain transparency. Responsible sourcing, based on due diligence guidance and standards, is becoming expected of companies that are involved in supply chains of raw materials.

For 30 years, additive manufacturing has made all sorts of promises. Yet machines remained slow, materials expensive, and printers too inconsistent for critical parts. And additive was costly. Today, however, the technology is turning that past on its head. While additive manufacturing is usually the most expensive way to make any part, it makes economic sense for supply chains. Which is why manufacturers of everything from aircraft and rolling stock to appliances, industrial equipment, and medical devices are looking at 3-D supply chain solutions—as are the U.S. Marines and UPS. This special report looks at how additive manufacturing is disrupting business models and transforming supply chains.

Full textAbstract:
Business practices to strengthen competitiveness increase the vulnerability of supply chains to risks. Risks that can adversely affect the effectiveness and efficiency of supply chain activities are events that disrupt the flow of information, materials, money, and products. Therefore, supply chain risk management is vital for companies. It is necessary to identify the risks that threaten the supply chain and prioritize them. In addition, examining the effects of risks on each other will determine the success of supply chain risk management. This study evaluates Turkey’s leading iron and steel company’s supply chain risk groups and sub-risks. The fuzzy DEMATEL method was used to determine the relative importance of the risks and the effects of the risks on each other. Results show that the most critical risk group is business risks. Business risk is followed by customer risks, supplier risks, transportation risks, environmental risks, and, finally, security risks. This study provides originality by evaluating the supply chain risks from a broader perspective.

Full textAbstract:
Today’s perishable food supply chains must be resilient to handle volatile demands, environmental restrictions, and disruptions in order to meet customers’ requirements. The enablers of the perishable food supply chain have not yet been explored. In this paper, a bibliometric systematic literature review has been conducted to identify the articles related to the perishable food supply chain. Next, with these identified articles, a map is created with bibliographic data using Vosviewer network visualization software, and then the enablers were identified by conducting keyword co-occurrence analysis. Later, a total interpretive structural modeling (TISM) is employed to analyze the interrelationships among enablers and then determine each enabler’s hierarchies, further representing them in a diagraph. Finally, the identified enablers are classified using cross-impact matrix multiplication applied to classification (MICMAC) analysis, and the graph is plotted. The results obtained from the deterministic assessment model provide the critical enablers for the perishable food supply chain. The obtained critical enablers and their hierarchies provide valuable insights for researchers in the context of perishable food supply chain for further study.

The article focuses on research on the functioning of liquid fuel supply chains, supplying troops carrying out peacekeeping and stabilisation operations in a foreign territory. Timely and complete supplies of fuels in war conditions determine the achievement of the assumed goals of a military operation. They often determine the health and life of soldiers. For this reason, the role of building the resilience of supply chains to disruptions, the type and frequency of which is entirely different from the undesirable events occurring in civil goods flows, is increasing. Therefore, the critical concept supporting building the resilience of fuel supply chains is risk management in these chains. The authors have developed a risk analysis method that integrates the Kaplan and Garrick approach and the fuzzy theory. The analysis identifies the existing disturbances and assigns them to the individual phases of the supply process. To illustrate the applicability of the proposed method, the authors analyse nine scenarios for the three most important stages of the procurement process in terms of building the resilience of the entire chain: Planning, delivery and storage. The fuzzy theory estimates the risk level for the analysed scenarios of adverse events. The proposed method is universal. It can be implemented to analyse the resistance of supply chains of other materials. It can also support the decision-making process for those responsible for planning, organisation and proper functioning of supply systems in all high-risk conditions, not only in the zone of war and stabilisation operations.

AbstractElectric vehicles are now proliferating based on technologies and components that in turn rely on the use of strategic materials and mineral resources. This review article discusses critical materials considerations for electric drive vehicles, focusing on the underlying component technologies and materials. These mainly include materials for advanced batteries, motors and electronics, lightweight structures, and other components specific to each vehicle type. Particularly strategic and widely used minerals and elements/structures for electric vehicles include nickel, cobalt, rare-earth minerals, lightweight and high strength steel alloys and underlying metals (e.g., magnesium and aluminum), carbon fiber, graphite and graphene, copper, and steel alloying materials. Additional key considerations include those around component and vehicle supply chains, repurposing and recycling vehicle components at end of vehicle life, and environmental and humanitarian considerations around the extraction and transport of the evolving set of materials needed for modern electric vehicle production.

Full textAbstract:
Centralized manufacturing and global supply chains have emerged as an efficient strategy for large-scale production of goods throughout the 20th century. However, while this system of production is highly efficient, it is not resilient. The COVID-19 pandemic has seen numerous supply chains fail to adapt to sudden changes in supply and demand, including those for goods critical to the pandemic response such as personal protective equipment. Here, we consider the production of the non-woven polypropylene filtration media used in face filtering respirators (FFRs). The FFR supply chain’s reliance on non-woven media sourced from large, centralized manufacturing facilities led to a supply chain failure. In this study, we present an alternative manufacturing strategy that allows us to move towards a more distributed manufacturing practice that is both scalable and robust. Specifically, we demonstrate that a fiber production technique known as centrifugal melt spinning can be implemented with modified, commercially-available cotton candy machines to produce nano- and microscale non-woven fibers. We evaluate several post processing strategies to transform the produced material into viable filtration media and then characterize these materials by measuring filtration efficiency and breathability, comparing them against equivalent materials used in commercially-available FFRs. Additionally, we demonstrate that waste plastic can be processed with this technique, enabling the development of distributed recycling strategies to address the growing plastic waste crisis. Since this method can be employed at small scales, it allows for the development of an adaptable and rapidly deployable distributed manufacturing network for non-woven materials that is financially accessible to more people than is currently possible.

Global supply chains play a critical role in many of the most pressing environmental stresses and social struggles identified by the United Nations’ Sustainable Development Goals (SDGs). Responding to calls from the global community, companies are adopting a variety of voluntary practices to improve the environmental and/or social management of their suppliers’ activities. We develop a global survey of 449 publicly listed companies in the food, textile, and wood-products sectors with annual reports in English to provide insight into how the private sector contributes to advancing the SDGs via such sustainable-sourcing practices. We find that while 52% of companies use at least one sustainable-sourcing practice, these practices are limited in scope; 71% relates to only one or a few input materials and 60.5% apply to only first-tier suppliers. We also find that sustainable-sourcing practices typically address a small subset of the sustainability challenges laid out by the SDGs, primarily focusing on labor rights and compliance with national laws. Consistent with existing hypotheses, companies that face consumer and civil society pressure are associated with a significantly higher probability of adopting sustainable-sourcing practices. Our findings highlight the opportunities and limitations of corporate sustainable-sourcing practices in addressing the myriad sustainability challenges facing our world today.

Full textAbstract:
The ability to provide uninterrupted power to military installations is paramount in executing a country’s national defense strategy. Microgrid architectures increase installation energy resilience through redundant local generation sources and the capability for grid independence. However, deliberate attacks from near-peer competitors can disrupt the associated supply chain network, thereby affecting mission critical loads. Utilizing an integrated discrete-time Markov chain and dynamic Bayesian network approach, we investigate disruption propagation throughout a supply chain network and quantify its mission impact on an islanded microgrid. We propose a novel methodology and an associated metric we term “energy resilience impact” to identify and address supply chain disruption risks to energy security. The proposed methodology addresses a gap in the literature and practice where it is assumed supply chains will not be disrupted during incidents involving microgrids. A case study of a fictional military installation is presented to demonstrate how installation energy managers can adopt this methodology for the design and improvement of military microgrids. The fictional case study shows how supply chain disruptions can impact the ability of a microgrid to successfully supply electricity to critical loads throughout an islanding event.

Full textAbstract:
The demand for minerals is set to increase in the future due to the global competition, industrialization in the developing countries, digitalization of the developed economies as well as the social and economic shocks in the course of a deep transformation of the international economic order. Dependence on the critical raw materials may soon replace the dependence on oil and gas. A reliable and sustainable supply of both primary and secondary raw materials, especially of the critical raw materials for the key technologies and strategic sectors such as the renewable energy, electric mobility, digital technologies, space and defense, is a prerequisite for achieving national security and independence. The new EU Industrial Strategy addresses security and sustainable development and calls for active action on critical raw materials and creation of sector-specific raw material alliances. This EU policy pursues a strategy of diversification in providing non-energy raw materials for EU value chains and ensuring the social welfare. Diversification of supply is related to reducing the dependencies in all areas by supplying primary raw materials from the EU, by increasing the supply of secondary raw materials through efficient use of resources, and by finding alternatives to scarce raw materials. One of the priority actions was to create a list of critical raw materials at the EU level.

Full textAbstract:
Fundamentals of critical minerals and their paramount role in the successful deployment of clean energy technologies in future transportation are assessed along with current global efforts to satisfy the needs of automotive supply chains and environmental concerns. An implementation of large quantities of minerals, in particular metals, into the manufacturing of strategic components of zero-emission vehicles will bring new challenges to energy security. As a result, a reduced dependency on conventional hydrocarbon resources may lead to new and unexpected interdependencies, including dependencies on raw materials. It is concluded that to minimize the impact of a metal-intensive transition to clean transportation, in addition to overcoming challenges with minerals mining and processing, further progress in understanding the properties of critical materials will be required to better correlate them with intended applications, to identify potential substitutions and to optimize their use through the sustainable exploration of their resources and a circular economy.

The U.S. economy and especially its manufacturing sector, is highly dependent on the supply of raw and semifinished materials. While the United States have extensive mineral resources and are a leading global materials producer, a high percent of many materials that are critical to U.S. manufacturing are imported. The so-called critical minerals are central to the manufacture of a wide range of high-tech products. These include mobile phones, computers, flat-screen monitors, solar panels, rechargeable batteries, air conditioners and defense industry technologies and products. Critical minerals play a significant role in USA national security, renewable energy development and infrastructure. The article provides an overview of trends in mineral supply risks and the critical factors that determine the mineral supply chain risks.

The level of uncertainty, unpredictability and complexity is magnified in a food supply chain as compared to the conventional supply chains such as automobile and FMCG. This is mainly because of the short product shelf life and the need of high variety. This necessitates the food industry to adopt various quick response systems to achieve effective supply chain management. The situation becomes even more critical when dealing with humanitarian relief operations where time window is very short (usually 24 hours). One of the solutions which are adopted in modern food supply chains is to locate cross-docking centre (CDC). Cross-docking is used to reduce the turnaround time of the food products. The practical situation is complex as it caters to multiple customers. The number of suppliers, in such cases, plays a significant role. Selection of a right CDC is, therefore, a crucial task. It is a strategic decision and needs to be taken by considering the relationships between each stakeholder present in the supply chain. In this article, we present an approach to select one (or few) CDC/s facilities among n CDCs. The method is based on the relationship between each actor (actors are the stakeholders in the supply chain). The relationship is in terms of the physical flow of materials or information flow or another kind of flows or relationships that connects them to form a network. These network characteristics are required to find out key stakeholders. The present article proposes the application of social network analysis (SNA) to analyse the characteristics of the network, thus helping supply chain managers to locate strategic CDCs considering both qualitative and quantitative aspects. The proposed methodology can be easily extended to locate temporary warehouse site in the context of humanitarian relief operations.

Full textAbstract:
The term “critical raw materials” (CRMs) refers to various metals and nonmetals that are crucial to Europe’s economic progress. Modern technologies enabling effective use and recyclability of CRMs are in critical demand for the EU industries. The use of CRMs, especially in the fields of biomedicine, aerospace, electric vehicles, and energy applications, is almost irreplaceable. Additive manufacturing (also referred to as 3D printing) is one of the key enabling technologies in the field of manufacturing which underpins the Fourth Industrial Revolution. 3D printing not only suppresses waste but also provides an efficient buy-to-fly ratio and possesses the potential to entirely change supply and distribution chains, significantly reducing costs and revolutionizing all logistics. This review provides comprehensive new insights into CRM-containing materials processed by modern additive manufacturing techniques and outlines the potential for increasing the efficiency of CRMs utilization and reducing the dependence on CRMs through wider industrial incorporation of AM and specifics of powder bed AM methods making them prime candidates for such developments.

Full textAbstract:
Sufficient supplies of critical raw materials (CRMs) for rapidly developing technologies, e.g., Li-ion batteries, wind turbines, photovoltaics, digitization, etc., have become one of the main economic challenges for the EU. Due to growing import dependency and associated risk of supply disruptions of these raw materials from third countries, there is a need to encourage their domestic production. This is an important starting point for EU value chains crucial for the sustainable economic growth of the whole Union. This contribution has evaluated the possibilities of CRMs supply from the EU’s primary sources. A three-step approach, including an assessment of CRMs’ importance for the EU’s economic growth, their significance in at least two of the three strategic industrial sectors (i.e., renewable energy, e-mobility, defense and aerospace), and their potential availability from EU mineral deposits, has been applied. Results of the analysis have shown that, of 29 critical mineral raw materials (according to the 2020 EC list), the potential to develop manufacturing from the Union mineral deposits exists for 11 CRMs, i.e., cobalt, graphite (natural), HREE, LREE, lithium, magnesium, niobium, PGMs, silicon metal, titanium, and tungsten, while some other CRMs, namely gallium, germanium, indium, and vanadium can be recovered as by-products. Measures to mitigate EU import dependency have been also proposed.

Full textAbstract:
Abstract Transparency in global value chains of materials, fuels, and food is critical for the implementation of sustainability policies. Such policies should be led by the G20, who represent more than 80% of global material, fuel, and food consumption. Multi-regional input–output analysis plays an important role for consumption-based assessment, including supply chains and their environmental impacts. However, previous accounting schemes were unable to fully assess the impacts of materials, fuels, and food. To close this gap, we provide an improved method to map key aspects of sustainability along value chains of materials, fuels, and food. The results show that the rise in global coal-related greenhouse gas (GHG) emissions between 1995 and 2015 was driven by the G20’s metals and construction materials industry. In 2015, the G20 accounted for 96% of global coal-related GHG emissions, of which almost half was from the extraction and processing of metals and construction materials in China and India. Major drivers include China’s rising infrastructure and exports of metals embodied in machinery, transport, and electronics consumed by other G20 members. In 2015, the vast majority (70%–95%) of the GHG emissions of metals consumed by the EU, USA, Canada, Australia, and other G20 members were emitted abroad, mostly in China. In contrast, hotspots in the impact displacement of water stress, land-use related biodiversity loss, and low-paid workforce involve the G20’s food imports from non-G20 members. Particularly high-income members have contributed to the G20’s rising environmental footprints by their increasing demand for materials, food, and fuels extracted and processed in lower-income regions with less strict environmental policies, higher water stress, and more biodiversity loss. Our results underline the G20’s importance of switching to renewable energy, substituting high-impact materials, improving supply chains, and using site-specific competitive advantages to reduce impacts on water and ecosystems.

Full textAbstract:
Batteries are the heart and the bottleneck of portable electronic systems. They power electronics and determine the system run time, with the size and volume determining factors in their design and implementation. Understanding the material properties of the battery components—anode, cathode, electrolyte, and separator—and their interaction is necessary to establish selection criteria based on their correlations with the battery metrics: capacity, current density, and cycle life. This review studies material used in the four battery components from the perspective and the impact of seven ions (Li+, Na+, K+, Zn2+,Ca2+, Mg2+,andAl3+), employed in commercial and research batteries. In addition, critical factors of sustainability of the supply chains—geographical raw materials origins vs. battery manufacturing companies and material properties (Young’s modulus vs. electric conductivity)—are mapped. These are key aspects toward identifying the supply chain vulnerabilities and gaps for batteries. In addition, two battery applications, smartphones and electric vehicles, in light of challenges in the current research, commercial fronts, and technical prospects, are discussed. Bringing the next generation of batteries necessitates a transition from advances in material to addressing the technical challenges, which the review has powered.

Full textAbstract:
Bullwhip effect is a threat observed in multi-echelon supply chains, which is one of the prominent indicators of inefficiencies in a supply chain. Primarily, bullwhip effect occurs as a result of disruptions in information and materials flow, lead-time delays, lack of coordination, and panic stocking amidst visibility into local risk factors. When bullwhip effect occurs, the demand variations entering the supply chain from the customer end amplifies gradually as it flows upstream towards the supplier ends. This may cause unused inventory and may later lead to wastage and obsolescence. Bullwhip effect can be curbed through many approaches. This study has focused on control theory approach that promotes small-scale control behaviors throughout the supply chain to dampen the bullwhip tidal waves. The approach investigated in this research is a combination of control system modeling and systems dynamics modeling, which is not researched adequately by bullwhip academics. Based on the investigations, a six-step approach for reducing Bullwhip effect is proposed in this research and illustrated with examples. The six-step approach comprises of first-level multi-echelon survey to derive the initial system dynamics model, second-level survey to collect primary data for all the variables and relationships formed, principal component analysis and Cronbach Alpha / split-half testing for reliability, verification, and validity testing and exploring the best optimal construct using structural equation modeling, and finally, applying controllers to the optimal systems dynamics model through interpretive analysis of the model.

Subject area Entrepreneurship, Corporate sustainability, CSR, Supply chain. Study level/applicability Master's courses: Entrepreneurship, Strategic management. Case overview In 2002, potential risks deriving from emerging normative demands in the CSR debate prompted Axel Springer (AS) to rethink their supply chain strategy for Russian wood. Being one of the first movers in CSR in the publishing business, AS realized that current practices could spark future public discussion that might put pressure on AS, a key player in these supply chains. In early 2002, AS and one of their main suppliers, Stora Enso, started a joint initiative to redesign the supply chain processes in two of the major Russian logging regions to improve their social and ecological performance. Sometime later, other major players in the publishing sector as well as critical reviewers from several non-governmental organizations (NGOs) were invited to participate in the design of the new voluntary sustainability initiative called “Tikhvin Chalna project”, the second phase of which was accomplished by the end of 2006. Expected learning outcomes Learn that organizations (specifically high-brand owners) are responsible for practices within their entire supply chains (social as well as environmental performance). Explore proactive corporate sustainability, CSR strategies are market but also institutional driven; Strategizing involves forming and transforming the rules, norms and standard models of customers as well as institutions such as NGOs or governmental bodies. Whether the initiator of such strategy is successful in increasing or manipulating demands is dependent on its resources and capabilities as well as on its network position. The case supports students in understanding resources being used to successfully transform or create institutional arrangements.

Full textAbstract:
There is an increasing need for supply chains that can rapidly respond to fluctuating demands and can provide customised products. This supply chain design requires the development of flexibility as a critical capability. To this end, firms are considering Additive Manufacturing (AM) as one strategic option that could enable such a capability. This paper develops a conceptual model that maps AM characteristics relevant to flexibility against key market disruption scenarios. Following the development of this model, a case study is undertaken to indicate the impact of adopting AM on supply chain flexibility from four major flexibility-related aspects: volume, mix, delivery, and new product introduction. An inter-process comparison is implemented in this case study using data collected from a manufacturing company that produces pipe fittings using Injection Moulding (IM). The supply chain employing IM in this case study shows greater volume and delivery flexibility levels (i.e., 65.68% and 92.8% for IM compared to 58.70% and 75.35% for AM, respectively) while the AM supply chain shows greater mix and new product introduction flexibility, indicated by the lower changeover time and cost of new product introduction to the system (i.e., 0.33 h and €0 for AM compared to 4.91 h and €30,000 for IM, respectively). This work will allow decision-makers to take timely decisions by providing useful information on the effect of AM adoption on supply chain flexibility in different sudden disruption scenarios such as demand uncertainty, demand variability, lead-time compression and product variety.

Full textAbstract:
Various stakeholders are involved in managing supply chain processes in construction. Suppliers can hardly tolerate upfront costs when faced with flaws in the payment pipeline. This is a serious problem in building construction that uses a large variety of materials as opposed to civil construction that requires fewer types of materials. Alternative secure payment systems are needed, and the use of cryptocurrencies can be an option. However, cryptocurrencies are seldom used in building construction projects due to several challenges that are mostly ignored in the existing literature. To fill this gap, this study investigates the use of cryptocurrencies in construction supply chains as an alternative payment solution to improve the financial performance of the stakeholders by taking advantage of this economical and traceable financial transaction system. The study involves exploratory, descriptive, and empirical survey research. Accordingly, a literature review, focus group discussions, and statistical analyses (Friedman test, Wilcoxon test, and Mann–Whitney U test) were performed. The results imply that a lack of technical knowledge about cryptocurrencies, fluctuations in the value of cryptocurrencies, limited market opportunities, security gaps, personal information required by cryptocurrency systems, no assurance of permanent use, and government actions limiting the use of cryptocurrencies were the most significant barriers against using cryptocurrencies in construction supply chain management. The findings are expected to provide critical information to construction professionals and regulatory agencies about the potential advantages and shortcomings of cryptocurrencies, hence motivating policymakers to create strategies that minimize the concerns of construction professionals about using cryptocurrencies in the building construction industry.

Full textAbstract:
<abstract> <p>Material databases are important tools to provide and store information from material research. Rising concerns about supply-chain risks to raw materials presents a need to incorporate raw-material market and end-use application data, beyond basic chemical and physical properties, into a material database. One key challenge for researchers working on critical materials is information scarcity and inconsistency. This paper introduces, as a result of a two-year project, a critical-material commodity database (CMCD) incorporated with a low-code web-based platform that allows easy access for users and simple updates for the authors. The main goal of this project was to educate material scientists on the applications having the most impact on the supply chain and current industrial specifications/markets for each application. The objective was to provide material researchers with harmonized information so that they could gain a better understanding of the market, focus their technologies on an application with a high potential for commercialization, and better contribute to supply-chain risk reduction. While the goal was met with high receptivity, several limitations stemmed from query design, distribution platform, and quality of data source. To overcome some of these limitations and expand on CMCD's potential, we are building a public webpage with an improved interface, better data organization, and higher extensibility.</p> </abstract>

Full textAbstract:
Abstract Aquaculture is identified as one of the critical food supplies in Malaysia. Due to the increasing demand for aquaculture products, the demand for protein sources for fish feed is also increased accordingly. Black soldier fly larvae is identified as one of the main protein sources that can be used in fish feed. Such larvae can be grown using different types of organic materials, such as food waste, agriculture waste, etc. As Malaysia is the second-largest palm oil producer in the world, therefore, a large number of agricultural wastes, also known as palm-based biomass (e.g., empty fruit bunches, mesocarp fibre, decanter cake, etc.) are generated annually. Based on the current industry practise, palm-based biomass can be converted into value-added products. However, using palm-based biomass as feedback to grow black soldier fly larvae is a relatively recent discovery. Thus, a viable supply chain model has yet to be established. In this work, a mathematical optimisation model is developed via commercial optimisation software (Lingo v. 16) to synthesise an optimum black soldier fly-based aquaculture feed supply chain that utilised palm–based biomass as the feedstock. Based on the optimised result, the annual operating cost of the aquaculture feed supply chain is estimated as RM 5.2 million.

Full textAbstract:
Shutdown activity is heavily reliant on supply chain functions, yet planning is frequently based on incorrect or incomplete information. The flow of materials and equipment is critical to preserving the schedule and budget; however, in most projects, the location of critical materials is manually tracked using spreadsheets or relies on limited enterprise resource planning (ERP) system functionality. This creates a number of problems, as there is no automated or accurate method of locating or ensuring material is available after it has left the manufacturer/supply base and is issued for installation; for example: Recent analysis showed 50–70% of materials are subject to some type of waste (rework, wait time, transport and over processing). Additional resources are required to manage constantly changing shutdown schedules and chase up material locations for job-card staging. Materials expedite costs for a four-week shutdown in a remote area can exceed up to $250,000 a week. Up to 30% of materials sent for a shutdown can be returned to inventory, which increases transport and labour costs. This extended abstract outlines the use of radio frequency identification (RFID) technology and lean supply chain techniques for improving plant shutdown performance, following two major Brownfield engineering projects that used technology innovations, such as active RFID tags, cloud software, solar energy, GPS, 3G/wireless network and mobile devices. RFID real-time location material tracking and LEAN principles were applied to critical materials to remove waste from shutdown processes, protect the integrity of the shutdown plan and help reduce costs by up to 14%.

The implementation of high-quality control of transport in various processes of supply chains, as well as in the field of cargo transportation, allows you to achieve a significant reduc-tion in transport costs. There are a large number of methods for optimizing transportation, the most common drawback of which is their inability to adapt to various critical unforeseen situa-tions. Using multi-agent models allows you to bypass the limitations of static models that use a strict schedule. To demonstrate the advantages of these models, we will use materials obtained as a result of computer modeling.

Full textAbstract:
Abstract The decarbonization of the transport sector requires a rapid expansion of global battery production and an adequate supply with raw materials currently produced in small volumes. We investigate whether battery production can be a bottleneck in the expansion of electric vehicles and specify the investment in capital and skills required to manage the transition. This may require a battery production rate in the range of 4–12 TWh/year, which entails the use of 19–50 Mt/year of materials. Strengthening the battery value chain requires a global effort in many sectors of the economy that will need to grow according to the battery demand, to avoid bottlenecks along the supply chains. Significant investment for the establishment of production facilities (150–300 billion USD in the next 30 years) and the employment of a large global workforce (400k–1 million) with specific knowledge and skillset are essential. However, the employment and investment required are uncertain given the relatively early development stage of the sector, the continuous advancements in the technology and the wide range of possible future demand. Finally, the deployment of novel battery technologies that are still in the development stage could reduce the demand for critical raw materials and require the partial or total redesign of production and recycling facilities affecting the investment needed for each factory.

Full textAbstract:
Pallets are among the most used returnable transport items (RTIs), and they are critical assets for a supply chain as they have significant environmental and economic impacts during their whole life cycle. Differently from other packaging products, pallets are specifically designed to be repeatably repaired and reinjected for use. While this environmentally is beneficial as it reduces waste, it can create complex interactions between the stakeholder-involved manufacturers, pallet providers, users and recyclers. Further, the number of different actors is usually high, and the flow of materials among them needs to be coordinated. In addition, different business models can be implemented (such as internal management versus outsourcing) as well as logistics alternatives (closed- versus open-loop). Thus, the aims of this study are first to propose a systematization of design and management decisions regarding the pallet supply chain; next, to review the state of the art models and tools adopted to support each decision process relying on an analysis of the archival literature published between 1978 and 2021 on pallet management, to summarize the main decision problems addressed by the different stakeholders involved in the pallet life cycle and the adopted methods, and, finally, to highlight potential existing research gaps. This effort helps to outline potential contributions towards more sustainable pallet supply chains and can support pallet operators and companies in evaluating solutions to increase the economic and environmental sustainability of their pallet management. Results show that the perspectives of the pallet provider and of the supply chain are the most widely addressed in the existing literature, while those of pallet manufacturers and repairers should be further analyzed.

Full textAbstract:
AbstractCritical raw materials (CRMs) are crucial for the transformation towards low carbon mobility. However, their production is often highly concentrated in a few countries, which leads to supply risks. Exemplified by the case of rare earth elements (REEs) and based on in-depth interviews with corporate executives from companies along the automotive supply chain, this contribution provides insights into the strategies of the European automotive industry to cope with these supply risks. Results show a lack of awareness of REE criticality studies and their outcomes in the past, the decisive role of price competitiveness when pursuing mitigation strategies and a lack of willingness or ability to engage in rare earth (RE) projects to get access to production output and secure supply. Overall, affected companies struggle to pursue long-term oriented strategies to secure their need for REEs. These findings are discussed with regard to the new demand for CRMs due to the shift to electric mobility and the specific challenges that the automotive industry faces.

For the U.S. to meet climate change and circular economy goals, to ensure good stewardship of critical materials, and to meet strategic supply chain goals for economic development and national security, a strong commercial recycling industry for recycling is vital. Identified by the blueprint developed by the Federal Consortium for Advanced Batteries (FCAB) and the Administration’s 100 Day report for high-capacity batteries as a key strategic focus area, recycling offers the strongest pathway to ensuring the U.S. can capitalize on the strong market demand for EVs and to ensure the materials are available for the U.S. to reintegrate into the supply chain. However, recycling alone is not enough to enable the U.S. goals to create a resilient and sustainable supply chain. Recycling needs to consider all end-of-life potential and challenges for lithium ion batteries, and the requalification of those materials in the battery supply chain. This requires a look at all supply chain segments as a whole to determine the areas for largest impact for sustainability and economic development.

Global consumption of materials is rising rapidly leading to an increase in environmental impacts associated with the supply chain. Similar issues also affect a set of materials strategic for the transition towards a sustainable energy production and distribution system: i.e. materials employed in renewable energy (wind turbines and photovoltaic panels), energy storage, electrolysers, electricity distribution networks and electric vehicle charging infrastructure. The analysis identifies, maps and defines a priority hierarchy for the environmental risks generated along the life-cycle of strategic raw materials. Standard construction material such as iron, steel and concrete showed the lowest environmental risks whereas platinum and iridium presented by far the highest impacts (respectively 24.098,04 and 14.732,51 kg CO2 eq, 353.893,39 and 215.934,28 MJ, and 140,24 and 83,20 m3 of water for 1 kg of raw material). Recycled materials have shown to enable the lowering of the environmental risk associated with some raw material production processes (i.e. copper, lead, aluminium, nickel, manganese), whereas specific materials (i.e. platinum, iridium, indium, dysprosium) and related applications will need to be monitored to guarantee a sustainable transition towards renewable energies.

In response to rising public demand for corporate, industrial, and private expansion, as well as low- cost residential construction, Turkey's development sector has burst in recent decades, and the Turkish government has placed a significant focus on industry. As a result, a methodical approach is required to cut down on money, time and waste. In the building business, dealing with the problem appears to be critical. It is debatable whether Supply Chain Management), a concept that first appeared and progressed in the automobile manufacturing industry, where it has found success, is one of the reliable practices that could primarily be the remedy for the construction industry's dispute, time, and cost excess. According to the construction sector, supply chain management has a lot of promise for increasing project productivity. This method, however, has not been effective in many nations, notably in Turkey. The major purpose of this study is to evaluate and examine the SCM implementation process in the Turkish construction sector based on previous studies, with an emphasis on efficient building procurement and supply. This will be accomplished by a rigorous literature analysis that will distinguish the industry's flaws and strengths. The benefits of SCM application in the construction sector, hurdles to successful SCM implementation in the purchase and delivery of building materials, and elements that reinforce the implementation will all be part of our study's model framework.

Our overriding thesis is that nuclear security measures are required in Indonesia as a matter of urgency given Indonesia’s current plans for the construction of nuclear power plants (NPP) and all the physical infrastructure and supply chains wherein nuclear materials is exposed to the general public and a target for terrorist attack. This work is divided into two parts: (1) an analysis and close reading of the existing nuclear regulatory regime of Indonesia, with the view of determining whether the existing regulations are sufficient to provide nuclear security measures that protect the general public, and (2) based on our analysis what kind of policies and legislative provisions should we have in order to better protect the public. The headline of our assessment is that there is a complete lack of legal basis for security measures and that it is recommended. From an international perspective the nuclear operating organization is within the penumbra of nuclear security standards established by the International Atomic Energy Agency (IAEA). However, while within the penumbra of the international standard for nuclear security, our assessment finds the Indonesian security measure is inadequate and potentially dangerously in effective and thus, in its current state behooves the Indonesian government to undertake a deep reformation of the legal framework of nuclear security in Indonesia.

Since the mid-20th century, logistics has evolved into a wide-ranging science of circulation involved in planning and managing flows of innumerable kinds. In this introductory essay, we take stock of the ascendancy and proliferation of logistics, proposing a critical engagement with the field. We argue that logistics is not limited to the management of supply chains, military or corporate. Rather, it is better understood as a calculative logic and spatial practice of circulation that is at the fore of the reorganization of capitalism and war. Viewed from this perspective, the rise of logistics has transformed not only the physical movement of materials but also the very rationality by which space is organized. It has remade economic and military space according to a universalizing logic of abstract flow, exacerbating existing patterns of uneven geographical development. Drawing on the articles that make up this themed issue, we propose that a critical approach to logistics is characterized by three core commitments: (1) a rejection of the field’s self-depiction as an apolitical science of management, along with a commitment to highlighting the relations of power and acts of violence that underpin it; (2) an interest in exposing the flaws, irrationalities, and vulnerabilities of logistical regimes; and (3) an orientation toward contestation and struggle within logistical networks.

With the increased size and complexity of liquefied natural gas (LNG) projects, supply-chain management has become a challenging process due to involvements of the remote location of the project site and the multiple stakeholders. The transparency and traceability of the supply-chain are critical as any surpluses or shortages of materials will put the project at risk. Currently, limited research has been conducted on LNG projects considering the total supply-chain perspective, which refers to all stages of materials tracking in off-site manufacturing, transportation, and site logistics. The purpose of this research is to propose a framework of a coordinated approach for supply-chain tracking in the LNG industry. Two focus group studies were organized to develop the proposed framework: One for LNG construction supply chain process development, and another for alternative tracking technologies selection. In addition, two experiments, namely off-site fabrication tracking and site logistics tracking, were conducted in a field to evaluate the feasibility of the proposed framework. Technology limitations were also discussed in terms of field implementation.

On the precipice of space exploration, smart fabrics, biochips and exoskeletons, the materiality of our wearable and body-centric future is a critical and political issue. If we are to develop technologies to take us to new places, we should be able to imagine radically different futures. The materials, tools and supply chains available to us seed the future we can build and are fuel for the possibilities we can imagine. Textile-based Do It Yourself (DIY) electronics have been suggested in Maker technology circles as an alternative path to electronics to broaden the diversity of those imagining our future, but they are still heavily divided by lines of gender, and hindered by supply chain availability. There are many textile-based technologies that have unique technical qualities to offer, but their development is stifled by systemic issues. This article suggests that e-textile technologies are a result of an entrenched system of power and act as a control method over the vision of the future rather than the suggested notion that they are an avenue of exploration. Using Erbu Kurbak’s concept of Lost Futures, and Elizabeth Ryan’s interoperation of wearable technology as immaterial labour, I make the case for e-textile practice being a trap and never equal contributor to the technological discourse.

The eucalyptus oil factory (PMKP) Sukun Ponorogo is an industry with complex supply chain activities, starting from the raw material’s procurement, production processes, distribution, and reverse logistics. Some of these activities may result in environmental problems. Therefore, measurement of its supply chain management (SCM) performance related to environmental conditions is critical. The green supply chain management (GSCM) concept can help the company to assess the supply chain's performance conditions that could harm the environment. This study aimed to assess the current SCM and measure its performance, as well as to evaluate the potential implementation on GSCM in the PMKP Sukun Ponorogo. The analytical network process (ANP) was used in this study, consisting of 36 key performance indicators (KPI) from five categories of plan, source, deliver, make, and return. The study results show that all KPIs from the responsiveness dimension in the deliver category have the lowest weight, thus require priority for improvement. The results of the scoring system using the objective matrix (OMAX) method indicated two KPIs were in the red category (or need improvement), including on-time delivery of raw materials to production site and the rejection rate of raw materials. This study suggested to improve the estimated delivery time for avoiding any delays during the production process. This improvement may support the company to continuously offer on-time production process and product’s distribution.

This process is facilitated by the availability of developed transport infrastructure, especially sea and river ports, attracting investment, including foreign in increasing crop production, productive land, increased role of the state in regulating strategic agri-food markets. At the same time, this powerful potential is not used effectively. Significant losses are due in particular to the creation of logistics of export flows, which in many cases make domestic food products uncompetitive in foreign markets, due to inflated costs of supply to final consumers. Such inflated costs indicate the lack of coordinated interaction of export-oriented chains and organizational and economic mechanisms, their regulation. Aim and tasks. The purpose of the study is to substantiate the scientific provisions and organizational and economic forms of logistics support for the integration of agri-food markets into global value chains. Research results. The current methodological approaches to the analysis of global value chains are analyzed, it is established that the main analytical indicator for agri-food markets and their individual sectors is a two-component "index of participation in global value chains". Low rates of participation of commodity markets in global chains are characteristic of developing countries and exporting countries of commodities with low levels of domestic value added, as evidenced by the sectoral analysis of agricultural markets. Analysis of problems with the efficiency of global agri-food value chains and specific market participants, practice shows that the producer achieves the greatest economic effect when it sells not raw materials, but products of processing, with increased value. In particular, the urgency of this issue is exacerbated by the need to use logistical reserves in the process of servicing export flows. Recent data suggest that as countries participate in global value chains, commodity growth rates increase. Value chains play an important role as a source of job creation. Thus, trade and supply in food hubs within the logistics chains of food markets stimulates the development of logistics as a critical component of global chains, as the most important problem is to supply products in the right quantity, quality, on time. The study also focuses on general market factors that affect the efficiency of specific value chains in the external dimension. Conclusion. The study proposes a conceptual approach to integrating agri-food markets into global value chains by creating agri-food hubs. The peculiarity of this concept is the formation of networks of specialized hubs that should serve the commodity flows of related markets. The basis of agri-food hubs should be formed by logistics functions related to marketing activities, tools for end-to-end planning of commodity supplies, and their institutional support. This will ensure efficient logistics routes of goods supply, strengthen cooperation between the links of the chains, fully take into account the specifics of the requirements of foreign consumer markets. Prospects for further research on this issue include bringing the rules of tax and customs legislation in line with international standards, ensuring insurance of export contracts and more.
