Healthcare has been facing rising challenges in recent years. To mitigate these issues, an appreciable amount of effort invested studies about 4.0. Despite the recognized importance this topic, its recentness and multidisciplinary character are obstacles to precise understanding. In light, paper aims provide a comprehensive view current development We systematically reviewed literature, which resulted 130 papers retrieved from Web Science Scopus databases. Quantitative qualitative analyses...

Purpose The purpose of this paper is to present a new hybrid approach based on criticality analysis and optimisation deal with spare parts inventory management in the initial provisioning phase mining industry. Spare represent significant part companies' expenditures, so it important develop approaches reduce total value these items. Design/methodology/approach This combines qualitative quantitative methods VED (vital, essential desirable) analysis, analytical hierarchical process (AHP),...

Postponement, which refers to the delay of final configuration and/or forward movement goods until consumer requests are received, is an important strategy increase agility and flexibility production logistics systems. This study aims carry out a bibliometric analysis systematic review relevant literature on postponement strategy. Bibliometrics was applied as quantitative technique using Web Science database CiteSpace software. As for qualitative analysis, selected publications carried out....

Purpose The purpose of this paper is to investigate the application postponement strategy by wineries in state Minas Gerais (Southeastern Brazil), order identify types adopted these companies, implementation process and results obtained after their adoption. Design/methodology/approach Twelve exploratory case studies were conducted wine-producing as well on-site visits semi-structured interviews with managers companies surveyed. Findings adoption form was verified studied mainly for table...

ABSTRACT Objective: This work aimed to estimate the avoidable COVID-19 cases and deaths with anticipation of vaccination, additional doses, effective non-pharmacological interventions in Brazil. Methods: We developed a susceptible-exposed-infectious-recovered-susceptible model based on epidemiological indicators morbidity mortality derived from data obtained Health Information System Ministry The number was estimated for different scenarios vaccination programs states Brazil (from March 8,...

Iron ore tailings (IOTs) need to be properly managed mitigate the environmental, social, and economic impacts of mining activities. To cope with this issue, we use data envelopment analysis (DEA) evaluate alternatives for using IOT in construction sector. The classical weight restriction output-oriented DEA models were used analysis. results show that ranking depends on aspect being evaluated. Concrete block is most environmentally friendly alternative when analysing both models. For social...

Iron ore tailings (IOT) from dams cause significant environmental, economic, and social impacts, which has motivated the search for reuse alternatives. In this scenario, present work uses reverse logistics to size resources required IOT road infrastructure. A system was modelled transport dam a processing plant then construction site of road. Resource capacity constraints operational limitations were considered, economic feasibility analysed. Two scenarios transportation on dam/plant route...

No presente trabalho, realizou-se uma análise comparativa das metodologias utilizadas para o despacho de caminhões em minas a céu aberto. Comparações entre essas contam com poucos trabalhos publicados na literatura. Metodologias baseadas programação linear e dinâmica heurística foram implementadas. Essas constituem as bases dos algoritmos alguns sistemas comercializados no Brasil. Foi desenvolvido um modelo simulação, fim se reproduzir comportamento operações lavra forma avaliar impacto...

O crescimento das universidades e consequente desenvolvimento bibliotecas universitárias torna necessária uma monitoração do desempenho, permitindo aos gestores acompanhar intervir na gestão para garantir a qualidade dos serviços oferecidos pelas mesmas. A técnica Análise Envoltória de Dados satisfaz essa necessidade. Essa possui dois modelos clássicos o calculo da eficiência, modelo CCR BCC. Quando aplicados em conjunto, é possível identificar as fontes ineficiência unidade análise. Assim,...

The tests for tracking diseases in newborns available through the National Neonatal Screening Program of Brazilian Unified Health Care System cover six diseases. Mass spectrometer equipment is needed to expand and more efficiently effectively detect new However, only four neonatal screening centers have capable carrying out extended test, expansion health service capacity should consider both rationalization costs comprehensiveness accessibility care population. This study uses analytics...

Blood supply chains (BSCs) face challenges in managing the production and inventory of blood components. We developed a simulation-optimisation approach to address products chains. This can determine size replenishment points for that balances demand, while maintaining acceptable levels wastage shortage. A simulation methodology is used represent complexities management An optimisation module, coupled with simulation, constraints related waste, shortages, levels. The was verified validated...

Purpose The purpose of this paper is to develop an approach evaluate the partial postponement strategy and compare it with make-to-stock (MTS) strategies in production table wine wineries state Minas Gerais (south-eastern Brazil). Design/methodology/approach An based on discrete event simulation was developed support decision-making sector. Simulation models were used analyse postponement, MTS production. These inspired by a typical producer selected from exploratory study conducted 12...

O presente trabalho propõe uma comparação entre dois métodos: a modelagem de redes filas e simulação computacional utilizadas para estimar medidas desempenho, por exemplo, o tempo médio total viagem num trecho sem bifurcações malha ferroviária, contendo um certo número pátios cruzamento.O objetivo desta é apresentar as duas ferramentas análise desempenho determinar capacidade dado nível serviço, também mostrar especificidades cada dos métodos.Para referidas análises foi modelado

O Serviço de Atendimento Móvel Urgências dos municípios Ouro Preto e Mariana opera em conjunto, forma contínua, durante 24 horas por dia, sete dias semana, utilizando quatro ambulâncias alocadas fixamente três bases espalhadas na região. Dado o grau incerteza do sistema aliado ao número parâmetros capazes interferir sua eficiência, mostra-se interessante determinar avaliar indicadores para realizar um diagnóstico da situação completa emergencial região, consonância com a análise qualidade...

A presente pesquisa analisou a eficiência econômica de 38 restaurantes universitários (Rus) que operavam por gestão terceirizada, em 2019, utilizando Análise Envoltória Dados, virtude do papel desempenhado estes como um mecanismo possibilita aos estudantes conclusão dos seus cursos, viabilizando as suas permanências na universidade e com isso, contribuindo para o desenvolvimento econômico visto universidades são lócus formação capital humano social . Além de, ponto vista regional, contribuir...
