INTERACTIVE EFFECT OF FIXED TIME ORDER STRATEGIES WITHIN A SUPPLY CHAIN ON ACTUAL IN-STOCK PROBABILITIES

This report mainly deals with the interactive effect of different in-stock probabilities used by every individual in a supply chain. Based on a simulation for 10,000 weeks, the effects of varying in-stock probabilities are observed. Based on these observations, an individual in a supply chain can take counter measures in order to avoid stock out chances hence maintaining profits.

Greening the Lean Supply Chain: il caso Lush Cosmetics

«La salute degli ecosistemi da cui dipendiamo, noi e tutte le altre specie, si sta aggravando più rapidamente che mai; stiamo compromettendo le stesse basi delle economie, della sussistenza, della sicurezza alimentare, della salute e della qualità della vita in tutto il mondo». Così il chimico R. Watson commentava un diffuso rapporto del 2019 delle Nazioni Unite sulla sconvolgente perdita di flora e fauna a livello globale. In questi anni sono stati infiniti gli appelli che citano l’astratto concetto delle «generazioni a venire», eppure, non tutte le aziende stanno agendo come dovrebbero. I rifiuti prodotti sono ancora molti, soprattutto quelli plastici da packaging. Alcune ideologie snelle, come il Lean Thinking, esistono da decenni e sono strettamente legate a quella che oggi chiamiamo Green Manufacturing. Entrambe propongono diversi strumenti per far fronte alla produzione di massa e agli sprechi: questi verranno trattati nella prima parte, e successivamente saranno impiegati, con il supporto del software «openLCA», per verificare il percorso dell’azienda protagonista dell’analisi, ovvero Lush Cosmetics. L’attenzione all’impatto ambientale che i propri prodotti possono provocare lungo l’intero ciclo di vita ha modellato la gestione interna di ciascun processo e, spontaneamente, si riflette sugli attori dell’intera supply chain: così, il comportamento di uno può ugualmente modificare, in questo caso positivamente, il lavoro di molti. Il seguente elaborato pone l’attenzione sulle problematiche migliorabili, proponendo diverse soluzioni alternative rispetto alla gestione attuale, seppur migliore di altre realtà. Infine, si vuole stimolare il consumatore verso una maggior consapevolezza delle conseguenze delle sue azioni, in fase di acquisto prima ed al momento dello smaltimento poi. I provvedimenti normativi, nazionali ed europei, possono funzionare solo se sostenuti da un consumo responsabile e dalla diffusione di una chiara ed efficace educazione ambientale.

Supply chain management as beyond operational efficiency

The orthodoxy of supply chain management (SCM) emphasises competitive advantage through increased operational efficiency and market responsiveness from production and distribution processes into the hands of consumers. It anticipates that future competition will be between chains rather than between firms. While well established in other industry sectors, the SCM concept is newly developed in the Australian agri-food sector. Critical review of the concept has identified key issues of power among channel members, processes of chain initiation and innovation, and the inability of SCM to offer a viable business strategy for some firms. Building on those insights, this paper examines the supply chain concept for horticulture. Horticultural products are characterised by perishability, heterogeneity and lags in production response to market signals. Producers’ profits are vulnerable to quantity, timing of supply and product specification. Many supply chains in smaller industries are loose, fragmented, interwoven, unstable and unique! Firms operating within these environments need an astute understanding of the chains, the hierarchy of channel members and their relative position. Effective business strategies – for individual firms and supply chains - need to be developed and redeveloped to accommodate the dynamic nature of horticulture. Two case studies are discussed as contributions to this early stage of the theoretical development of supply chain management. The SCM concept also has implications for horticultural researchers, involving a wider range of industry stakeholders, technical problems and research skills. As for business management, the usefulness of the concept will depend on its capacity to increase responsiveness to customers’ preferences and customer value.

Supply chain management

Nos últimos anos, a economia mundial e a economia brasileira têm sofrido mudanças importantes. Fusões, aquisições e alianças estratégicas têm se multiplicado. Parte considerável destas mudanças relaciona-se com profundas alterações nos sistemas de valores de todos os segmentos industriais. A busca da competitividade relaciona-se cada vez mais com a busca do ótimo sistêmico além das fronteiras da empresa. Neste contexto, a administração logística ganha nova dimensão, envolvendo a integração de todas as atividades ao longo da cadeia de valores e do sistema de valores, das matérias-primas ao cliente final. O objetivo deste trabalho é (re)situar a administração logística no contexto de mudanças, enfatizando a metodologia da gestão da cadeia de demanda (supply chain management).

GREEN SUPPLY CHAIN: PROTAGONISTA OU COADJUVANTE NO BRASIL?

Questões ambientais passaram a ser introduzidas com maior frequência nos negócios empresariais. Quanto à cadeia de suprimentos, Green Supply Chain Management (GSCM) surge como novo enfoque à responsabilidade das empresas com o meio ambiente. Este artigo objetiva analisar a difusão do conceito e das práticas de GSCM no cenário brasileiro. Para tanto, foram realizadas entrevistas com especialistas do tema cadeia de suprimentos na área de Administração no Brasil. Os resultados indicam que as razões para o lento desenvolvimento do conceito podem relacionar-se com características do mercado nacional, foco empresarial em aspectos internos, falta de legislação rígida e baixa pressão dos consumidores. Especialistas percebem, entretanto, boas perspectivas para o futuro das discussões da temática no País, em virtude da Política Nacional dos Resíduos Sólidos, de pressões do mercado internacional e da busca por certificação ambiental. Este estudo procurou fomentar novas discussões sobre GSCM no Brasil.

SUPPLY CHAIN RESILIENCE ANALYSIS: A BRAZILIAN AUTOMOTIVE CASE

Supply chain (SC) resilience and flexibility are important research topics receiving growing attention. However, the academic literature needs empirical studies on SC resilience capable of investigating the inter-organizational components of flexibility along different tiers. Therefore, this paper analyzes the main lack of flexibilities in three Brazilian automotive SCs that limit their resilience and therefore their capacity to better support and meet the demand changes in the marketplace. A multi-tier case study approach is adopted. Research findings identify lack of flexibilities in different tiers that inhibit the SC resilience as well as manufacturing and SC flexibilities that build SC resilience. The findings also highlight that the same SC may have the flexibility to be resilient for one of its products but not for another product, what sheds new lights on the academic literature. Finally, flexible SCs should be designed to increase SC resilience to cope with mishaps as significant demand changes.

The role of European "ro-ro" port terminals in the automotive supply chain management

The aim of this paper is concerned with the design and development of a functional framework for maritime mode integration in European automotive supply chain management when considering outbound distribution. Furthermore, it provides a readjustment of traditional concepts and terminology with findings that the role of ro-ro port terminals should be considered as decoupling points, poles and postponement platforms. Case studies examine relevant Western European ro-ro port terminals for cars and respective links to assembly/factories of vehicles localized in the hinterland and concludes that ro-ro port terminals reduce logistical friction and impedance, as well as promote space/time compression.

Supply chain optimization of residual forestry biomass for bioenergy production: the case study of Portugal

Within a large set of renewable energies being explored to tackle energy sourcing problems, bioenergy can represent an attractive solution if effectively managed. The supply chain design supported by mathematical programming can be used as a decision support tool to the successful bioenergy production systems establishment. This strategic decision problem is addressed in this paper where we intent to study the design of the residual forestry biomass to bioelectricity production in the Portuguese context. In order to contribute to attain better solutions a mixed integer linear programming (MILP) model is developed and applied in order to optimize the design and planning of the bioenergy supply chain. While minimizing the total supply chain cost the production energy facilities capacity and location are defined. The model also includes the optimal selection of biomass amounts and sources, the transportation modes selection, and links that must be established for biomass transportation and products delivers to markets. Results illustrate the positive contribution of the mathematical programming approach to achieve viable economic solutions. Sensitivity analysis on the most uncertain parameters was performed: biomass availability, transportation costs, fixed operating costs and investment costs. (C) 2015 Elsevier Ltd. All rights reserved.
