<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>

Any change of the raw material sources for glazes, economically, ecologically motivated, and also from the glaze quality point of view, is conditioned by the molecular formula rationalization and by the variation limits of the molecular formula, respectively. The proper glaze compositions are placed within their limit variation intervals with optimized processing and utilization properties. For this purpose, the rationalization criteria and procedures of molecular formulas are summarized in the present paper, as well as the results referring to their rationalization obtained in the authors� previous work. Thus, one starts from a base of raw materials that are selected, usable and also accessible for the design and producing of the glazes. On these bases the groundwork and the design equation for the glaze recipes are developed, exemplified for a single glaze. For an easy access to results, computer programs are used for an easy access to results.

Difficult Challenge

The lithium ion supply chain is set to grow in both size and importance over the coming decade due to government-led efforts to decarbonize economies and declining costs of lithium ion batteries used in electronics and transportation. With forecasts of demand for lithium chemicals alone forecast to grow by three times later this decade, at least $10B USD is needed to flow into the upstream supply chain to ensure an efficient and timely build-out. Significant additional capital is needed for other portions of the supply chain such as other raw materials, cathode or anode production, and battery cell manufacturing. Recent exogenous shocks such as the US-China trade war and coronavirus disease 2019 (COVID-19) pandemic have made securing adequate capital for the supply chain a difficult challenge. Without the steady stream of funding for new mine and chemical conversion capacity, widespread adoption of electric vehicles (EVs) could be put at risk. This paper discusses the current structure of the lithium ion supply chain with a focus on raw material production and the need for and challenges associated with securing adequate capital in an industry that has, to date, not experienced such a robust growth profile.

Supply chain of agricultural commodities becomes a major concern of Indonesian scholars and practitioners. Many companies engaged in this industry unable to survive in the market. This is contrary to the natural conditions of Indonesia with abundant natural resources and plenty of commodity producers. Problems often arise in the field of supply chain risk which link to commodities in Indonesia, among others: price fluctuation, the scarcity of the commodity, supply and demand are not balanced, distribution and production costs are expensive, raw material commodities that are imported, and natural disasters. Companies which engaged in agricultural business have high risk of survival and not even grow. To overcome this challenges the this chapter intend to review supply chain management concept by look at risk consideration may arise in the business uncertainties. The lack of studies to investigate the risk factors in agribusiness makes this study contribute to the supply chain literature.

A large number of sand shrubs have been planted in western China, especially in Inner Mongolia. Sand shrubs produce a large amount of stump residue, and wood biomass power generation enterprises that use stump residue as raw materials have emerged in Wushen Banner and other areas. In this paper, the Mixed Integer Linear Programming (MILP) model is used to optimize the raw material supply chain of forest biomass power generation enterprises. Optimizations with different objectives represent the choices of different stakeholders. The optimization results are listed as follows. (1) The self-issuance behavior of enterprises is inconsistent with the enterprise behavior required by social planners; (2) When social planners only pay attention to environmental benefits, the utilization rate of raw materials in towns located far from a power plant will be greatly reduced, which is not conducive for the reuse of stump residue; (3) When social planners consider economic, environmental, and social benefits simultaneously, the utilization rate of raw materials in each town will be significantly improved, resources will be effectively utilized, and certain economic benefits will be realized; (4) It is possible to reduce the difficulty of achieving optimization goals by promoting industrial development and encouraging technological progress.

This article discusses why companies need to shore up their supply chains to guard against disasters. Supply chains, which provide raw materials and distribute finished goods to end customers, now extend through many independent companies, and nearly every chain is global. As a consequence, major events from around the world, both natural and man-made, affect the flow of goods and have an increasingly sharp and visibly evident impact on businesses. It is therefore essential that companies identify their entire upstream supply chain—not just their tier-one suppliers but all suppliers and subsuppliers . They should try to understand their downstream customers and intermediaries as well. Businesses also need to conduct a vulnerability assessment for their extended supply chain, not just internal operations. This includes assessing geographic risk, organizational risk, embedded risk, and supplier risk. Organizations should also develop a plan to create a culture that supports supply chain risk management, including active risk monitoring, education, training, and simulation exercises.

Lot Sizing And Scheduling

The joint lot sizing and scheduling problem can be considered as an evolvement of the joint economic lot size problem which has drawn researchers’ interests for decades. The objective of this paper is to find the effect of a capacitated multi-period supply chain design parameters on joint lot sizing and scheduling decisions for different holding and penalty costs. The supply chain deals with two raw materials suppliers. The production facility produces two products which are shipped to customers through distribution centers. A mathematical model is developed to determine optimum quantities of purchased raw materials, production schedule (MPS), delivered quantities and raw material and products inventory for predetermined number of periods. The model is solved to maximize total supply chain profits. Results showed that at high capacity and low holding cost, the supply chain tends to produce only one product each period, for limited capacity and high value of holding cost, the supply chain may produce the two products together each period.

 Udang merupakan komoditas unggulan ekspor Indonesia yang memerlukan bahan baku yang berkualitas dan aman. Untuk mendapatkan bahan baku udang yang sesuai, seluruh anggota rantai pasok harus menerapkan persyaratan jaminan mutu dan keamanan hasil perikanan sesuai Kepmen KP Nomor: 52A/KEPMEN-KP/2013. Tujuan penelitian ini adalah mengevaluasi penerapan persyaratan jaminan mutu dan keamanan hasil perikanan sepanjang rantai pasok bahan baku udang untuk unit pengolahan ikan (UPI) di Jakarta Utara. Dua UPI telah dipilih menjadi responden untuk dirunut ke hulu mengenai pemenuhan persyaratan dimaksud. Pengumpulan data dilakukan melalui survei, observasi dan wawancara kepada UPI, pengumpul/pemasok, pembudidaya dan pembenih. Analisis kesenjangan dan uji korelasi berganda digunakan untuk menilai kesesuaian penerapan persyaratan jaminan mutu dan keamanan hasil perikanan. Hasil identifikasi menunjukkan masih terdapat kesenjangan penerapan yang dilakukan oleh pembudidaya dan pengumpul/pemasok dengan standar yang ada. Tingkat kesesuaian pada pembudidaya 58% (kurang sesuai) dan pemasok 48% (tidak sesuai). Apresiasi UPI terhadap mutu dan keamanan hasil perikanan masih belum memadai, diduga karena permintaan di pasar global sangat tinggi sedangkan pasokannya tidak sesuai. Penerbitan sertifikat yang terpisah-pisah di antara rantai pasok diduga menjadi salah satu penyebab. Diperlukan perubahan strategi kebijakan dalam pelaksanaan sistem sertifikasi udang budidaya untuk ekspor yang terintegrasi dalam satu sertifikat.Shrimp is Indonesia's leading export commodity that requires quality and safe raw materials. To get appropriate shrimp raw materials, all members of the supply chain must apply the quality assurance and safety requirements of fishery products in accordance with Ministerial Decree KP Number: 52A/KEPMEN-KP/2013. This study aimed to evaluate the implementation of quality assurance and safety requirements for fishery products along the supply chain of cultured shrimp raw material suppliers for fish processing units (UPI) in North Jakarta. Two UPIs have been selected as respondents whose suppliers were evaluated regarding the fulfillment of the specified requirements. Data collection was carried out through surveys, observations, and interviews with UPI, collectors/suppliers, farmers, and breeders. Gap analysis and multiple correlation tests were used to assess the appropriateness of the implementation of quality assurance and fishery product safety requirements. The results show that gaps existed between the implementation of the requirement by farmers and suppliers compared with existing standards. The implementation level for farmers is 58% (less according) and the supplier 48% (not according). It was observed that UPI's appreciation of the quality and safety of fishery products was inadequate, allegedly because demand in the global market is very high while the supply does not meet the demand. Issuance of separate quality and safety certificates along the supply chain are believed to be one of the causes. There is a need to change the policy strategy in implementing the shrimp culture certification system for export which can be integrated into one certificate.
