The Impact

Even though the main EU regulations concerning food traceability have already entered to force since many years, we still remark very wide and impacting product recalls, which often involve simultaneously large territories and many countries. This is a clear sign that current traceability procedures and systems, when implemented with the only aim of respecting mandatory policies, are not effective, and that there are some aspects that are at present underestimated, and therefore should be attentively reconsidered. In particular, the sole adoption of the so-called “one step back-one step forward traceability” to comply the EC Regulation 178/2002, where every actor in the chain handles merely the data coming from his supplier and those sent to his client, is in fact not sufficient to control and to limit the impact of a recall action after a risk notification. Recent studies on lots dispersion and routing demonstrate that each stakeholder has to plan his activities (production, transformation or distribution) according to specific criteria that allow pre-emptively estimating and limiting the range action of a possible recall. Moreover, these new and very recently proposed techniques still present some limits; first of all the problem of traceability of bulk products (e.g. liquids, powders, grains, crystals) during production phases that involve mixing operations of several lots of different/same materials. In fact, current traceability practices are in most cases unable to deal efficiently with this kind of products, and, in order to compensate the lack of knowledge about lot composition, typically resort to the adoption of very large lots, based for instance on a considered production period. Aim of this paper is to present recent advances in the design of supply chain traceability systems, discussing problems that are still open and are nowadays subject of research.

The Impact

This paper aims to develop a new bi-level game model for joint pricing and inventory decisions in a competitive supply chain consisting of a dominant manufacturer, who produces single perishable product from deteriorating raw materials, and two follower retailers who face nonlinear price-dependent demand and operate under Cournot assumptions. Three levels of warehousing including raw material warehouse, final product warehouse, and retail warehouses with exponential deterioration rates are considered to explore the joint impact of deterioration rate and price elasticity on the equilibrium inventory decisions. A Stackelberg-Nash-Cournot model is developed to seek the equilibrium prices, quantities, and replenishment cycles and is solved through an exact methodology. A numerical example is presented to validate the proposed model and comprehensive sensitivity analyses are carried out to measure the impact of the model’s key parameters including the deterioration rate in the producer’s and the retailers’ warehouses, the retail and competitor price elasticity, and the market scale on the equilibrium.

Indonesia's non-migas industries will play a key role in improving economic impact for the country, as it is consistent with the gross domestic product (wb) of non-migas industries. In the meantime, there are some negative effects that are mitigated, one of which is to the environment, in which a company must be required to increase its corporate performance in order to keep up with the competition and still look at the impact of the environment. As for the method of supply chain management using scor approach methods. Because beyond getting a knowledge of the company's performance from the intermal process, measuring performance using company scor methods has also been able to recognize the company's environmental performance, it can also increase attention to a wide range of negaific impacts that would affect the life cycles of the company's xyz corporation, a packaged alcohol corporation that already has food and environmental security standards, Yet this company has never been able to consolidate green supphy chain management. The company's repairs on this study have yet to be determined by researchers measuring the kincing of the supply chain using scor method approaches, which, in turn, have been supported by ahp sound and value in standardization by snorm DE Boer to get more accurate results. From the calculations presented at trafic light, the company's performance of 89 31 means that the company's performance is good but there are 4 kpi units of 21 PI that fall in the red category which means that all four must be made in the red category With the cooperation of both verbal and non-verbal partners, socializing with their employees can also replace energy-efficient sensors. And exercised regular control over the raw materials and the correct scheduling flow of information and material flow.

Hyperbranched Polyamide

Abstract In order to achieve enhanced physical performance of polylactic acid (PLA), the hyperbranched polyamide (HBPA) was synthesized by "one-step" as raw materials, and added as a modifier to the PLA matrix. The HBPA/PLA blend was prepared through the twin screw extrusion process and the injection molding process. The results showed that, compared with pure PLA, the tensile strength of HBPA/PLA blends increased by 41.8% while the elongation at break and the impact strength basically unchanged. The addition of HBPA does not affect the glass transition temperature (Tg) and crystallization of PLA significantly, but can improve the thermal deformation temperature of PLA. HBPA acted as a nucleant for PLA during iso-temperature crystallization. HBPA could form hydrogen bonds and chemical crosslinks with PLA, thus exhibits excellent reinforcing effect for PLA.

The Impact

The global order has suddenly changed due to the COVID-19 pandemic. Many countries, including Indonesia, have applied lockdown policies to stop the spread of COVID-19. Lockdown policies have disrupted the supply of raw materials and the demand for finished goods. The manufacturing industry is one of the sectors that has suffered most in this situation, and they have struggled to reconfigure their internal and external supply chain network and partnership. This study examined the impact of internal integration, supply chain partnership, supply chain agility, and supply chain resilience on sustainable advantage. The participants of this study were from manufacturing companies in Indonesia. For data collection, a questionnaire was used, with a five-point Likert scale to obtain the respondents’ opinions. Using Google Form link, the questionnaire was distributed via email and the WhatsApp social media application to the predetermined set of manufacturing companies. Respondents filled out 672 questionnaires, and 456 respondents (corresponding to 67.86%) filled it out correctly and were considered valid for further analysis. Partial least squares (PLS) regression was used to analyze the data using the SmartPLS software version 3.3. The results supported all nine hypotheses proposed. Internal integration through interdepartmental data sharing affects supply chain (SC) partnerships, SC agility, and SC resilience. Moreover, SC partnerships, through the on-time delivery of materials and by coping with changing demand, improve SC agility, SC resilience, and sustainable advantages. SC agility, in keeping the production process running normally and regulating the production capacity, affects SC resilience and sustainable advantage. SC resilience improves sustainable advantage by providing timely product delivery and reliable sales volumes in pandemic conditions. These results provide insights for managers into enhancing the sustainable advantage by improving supply chain agility, supply chain resilience, and supply chain partnerships. This study could contribute and extend the acceptance of previous studies in the context of the manufacturing industry.
