Um modelo exploratório para o processo de compra de MRO baseadas na internet Michelin Brasil

A presente dissertação tem por objetivo criar um modelo de compras de rMRO (manutenção, reparos e operações) baseado na Internet, para a Michelin no Brasil. Atualmente, a empresa Michelin está participando de uma comunidade virtual, sob a forma de um "vertal", criada pelas maiores empresas da indústria de pneu e borracha (Michelin, Goodyear, Pirelli, Continental, Cooper, Sumitomo, entre outras), e cuja intenção é desenvolver uma praça de mercado global para realização das suas compras e aprovisionamentos. A Rubbernetwork.com (RNC) foi fundada como uma empresa independente, reunindo o conjunto das compras da indústria de pneu e borracha, representando um valor de mais de cinqüenta bilhões de dólares por ano gastos em matérias-primas, equipamentos, maquinário, bens e serviços. Esta central de compras permitirá a seus membros aumentar a eficácia de suas operações e realizar economias substanciais nos custos de transação. Cada transação será protegida por apropriados sistemas advindos da implementação da tecnologia da informação, a fim de garantir a confidencialidade de todas as atividades comerciais de cada empresa individualmente. Os membros participantes estão convencidos de que a iniciativa possibilitará economias significativas e melhorará a eficiência de suas cadeias de valor. A comunidade virtual será aberta a todos os fabricantes e fornecedores relacionados à indústria de pneu e borracha, sendo também bem vindas oportunidades 2 de interação com outras comunidades virtuais, especialmente aquelas associadas à indústria automotiva. É dentro do contexto de implementação do projeto Rubbernetwork.com (RNC) que a dissertação se desenvolverá, tecendo estratégias e modelos de negócios concernentes aos processos de compras relacionados a MRO (manutenção, reparos e operações). O desenvolvimento de um "vertal" na Internet não impede que portais horizontais complementares, e não excludentes, sejam também acrescidos como alternativa de negócios. Há de se dar um tratamento específico às compras diárias que envolvem um grande número de diferentes fornecedores, várias áreas internas na empresa e consomem tempo desnecessário em trabalhos burocráticos, sem fins estratégicos. Cabe ressaltar que tal categoria de compras, denominada MRO, apesar de seu baixo valor por produto ou serviço adquirido, gera um elevado volume de transações e um alto impacto operacional. Pelo fato de tratar-se de uma experiência inovadora em setor de características próprias - mercado de pneu e borracha -, e de estar-se criando uma expectativa de cooperação entre empresas concorrentes, em busca da racionalização do processo de compras e divisão de custos operacionais, a metodologia utilizada, quanto aos seus fins, será exploratória e aplicada I. Quanto aos meios de investigação, a pesquisa realizada será: de campo, estudo de caso e bibliográfica. O universo da pesquisa restringir-se-á à empresa Michelin, onde o processo de compras de MRO baseado na Internet será contemplado, através de levantamento de dados nos E.UA e França, a fim de propor-se um modelo para a Michelin Brasil.

The suppliers selection problem: a case study

The effective supplier evaluation and purchasing processes are of vital importance to business organizations, making the suppliers selection problem a fundamental key issue to their success. We consider a complex supplier selection problem with multiple products where minimum package quantities, minimum order values related to delivery costs, and discounted pricing schemes are taken into account. Our main contribution is to present a mixed integer linear programming (MILP) model for this supplier selection problem. The model is used to solve several examples including three real case studies from an electronic equipment assembly company.

Procurement strategies in the health sector: How advanced are procurement processes in Portuguese hospitals

A Work Project, presented as part of the requirements for the Award of a Masters Degree in Management from the NOVA – School of Business and Economics

Development of Order-Delivery Process in Purchasing

Diplomityön tavoitteena oli kehittää Fazer Suklaan oston tilaus-toimitusprosesseja, jotta raaka-aineet ja pakkausmateriaalit pystytään hoitamaan mahdollisimman tehokkaasti. Ensin selvitettiin kirjallisuuden avulla tilaus-toimitusprosessin päävaiheet ja niihin vaikuttavat tekijät. Empiirisessä osassa lähdettiin liikkeelle käymällä läpi Fazer Suklaan oston nykytilanne, joka tehtiin ostajille suunnatun aikaselvityksen, haastatteluiden ja nykyisten tilaus-toimitusprosessien kuvaamisen avulla. Tavoitetilanteen rakentaminen aloitettiin ostettavien materiaalien ja toimittajien luokittelemisella. Tämän perusteella nämä materiaalit voitiin jakaa kolmen eri tilaus toimitusprosessin alle. Automaattisessa tilaus-toimitusprosessissa eri vaiheet automatisoidaan yhdessäavain toimittajien kanssa. Puoliautomaattinen prosessi perustuu systeemiin, jossa toimittaja näkee internetin kautta Fazerin tuotantosuunnitelman ja tekee tämän perusteella materiaalien täydennykset. Yksinkertaisessa prosessissa ostoarvoltaan alhaiset materiaalit hoidetaan mahdollisimman lähellä käyttöpistettä ja prosessin vaiheet tehdään mandollisimman pienellä työmäärällä. Tavoiteprosessien implementoinnilla todettiin suurimmiksi eduiksi prosessivaiheiden vähentyminen ja manuaalisen työn automatisoituminen. Tätä kautta saatiin prosessin eri vaiheiden työmäärää vähennettyä, sekä alennettua varastotasoja ja näin tilaus toimitusprosessin kokonaiskustannuksia pystyttiin pienentämään.

Assessing e-procurement System for Improving the Purchasing Operations

Diplomityön tavoitteena oli luoda suunnitelma elektronisen hankintatoimen aloittamiseksi, analysoimalla nykyisiä ostoprosesseja ja konsernin laajuista elektronista hankintajärjestelmää. Työ pohjautuu yritysten väliseen elektroniseen kauppaan, elektroniseen hankintatoimeen ja systeemisuunnitteluun liittyvään kirjallisuuteen. Työssä tehdyn suunnitelman tarkoituksena on auttaa Siemens Oy:tä siirtymään uuteen elektroniseen ostotoimintaan. Elektroniselle ostotoiminnalle suunniteltiin tavoitteet ja näitä vastaavat vaatimukset. Elektronisen hankintajärjestelmän analysointi perustuu kirjallisuudessa esitettyihin järjestelmän elinkaari-mallin vaiheisiin. Analysoinnin tarkoituksena oli saada selville järjestelmän soveltuvuus Siemens Oy: n liiketoimintaympäristöön, prosesseihin ja vaatimuksiin. Elektronisen hankintatoiminnan etuja ovat liiketoiminta prosessien johtamisen parantuminen, kustannusten väheneminen sekä taloudellisen suorituskyvyn lisääntyminen. Elektronisen hankintatoiminnan aloittaminen vaatii kuitenkin huolellista suunnittelua. Työssä tehdyt suunnitelmat ja analysoinnit auttavat arvioidessa järjestelmän sopivuutta Siemens Oy: n vaatimuksiin. Oikean ja toimivan järjestelmän valinta ei kuitenkaan takaa elektronisesta hankintatoiminnasta hyötymistä. Tärkeimpiä jatkotoimenpiteitä onkin suorittaa kustannus/hyöty analyysi ja arvioida toimittajien halukkuutta ja kykyjä osallistua markkinapaikkaan.

Electronic Data Interchange in Logistics Processes

Tämän diplomityön tarkoituksena oli tehdä selvitys EDI:in liittyvistä vaikutuksista, tarpeista ja eduista sekä valmistella Oracle Applications- toiminnanohjausjärjestelmän EDI Gateway- modulin ottamista tuotantokäyttöön. Tietoa tarvekartoitukseen saatiin keskustelujen avulla. Uusia kaupallisista lähtökohdista johdettuja, yritysten väliseen kaupankäyntiin ja internet-teknologian hyödyntämiseen kehitettyjä aloitteita käsiteltiin EDI-näkökulmasta tulevaisuutta varten. Ajankohtaisinta tietoa tätä diplomityötä varten löydettiin myös internetistä. Tämän jälkeen oli mahdollista toteuttaa sopivan laaja mutta rajattu EDI pilottiprojekti EDI-konseptin luomista varten. EDI:n vaikutuksiin ostossa keskityttiin tässä diplomityössä enemmän ja EDI:ä päätettiin soveltaa aluksi ostotilauksissa. EDI:n hyötyjä on vaikea mitata numeerisesti. Suurta määrää rahaa tai tuoteyksiköitä on käsiteltävä EDI-partnerin kanssa riittävän usein. EDI:n käyttöönottovaiheessa pääongelmat ovat sovelluksiin liittyviä tietotekniikkaongelmia. Selvityksistä ja EDI-projektista saatu tieto on mahdollista hyödyntää jatkokehityksessä. Lisätoimenpiteitä tarvitaan kokonaan toimivan järjestelmän luomiseksi.

Developing Launching Processes — A Case Study

New product launches are becoming more and more important to companies around the globe. Being first on the market is a good place to be, and it will mostly likely bring the best profits. Gaining that desired position requires a lot of work where cooperation inside as well as outside of the company need to be in line. This thesis discusses launching processes in a pharmaceutical firm. The topic is looked at from supply chain management's point of view where purchasing department's role is emphasized. Additionally, launching strategies related to launches are investigated and the idea of internal alignment is introduced. Moreover, the topic is examined in project and process management perspective; how with the tools of project and process management the launching processes could be improved. The main findings reveal that there are many improvement points in the current launching process. Problems in the areas of information exchange, leadership and internal alignment were discovered yet trust and confidence for the better future compound the interviewees. This study presents what are the most important factors for a successful product launch and how the current processes could be streamlined.

Purchasing and supply management capabilities in Finnish medium-sized enterprises

Purchasing and supply management (PSM) has become increasingly important for companies to survive in current highly competitive market. Increased outsourcing has extended the role of PSM, making external resource management and supplier relationships critical success factors in business. However, the recent research has mainly concentrated on large enterprises. Therefore the PSM issues related to medium-sized enterprises represent a significant research area. The thesis aims to explore the status and role of PSM in Finnish medium-sized firms, understand how strategic companies consider PSM to be, clarify what are the competence requirements for PSM professionals, and increase the understanding of PSM capabilities needed from the points view of individual competence and organisational capabilities. The study uses data that was collected in 2007 from purchasing executives at the director/CEO level representing a sample of 94 Finnish firms. 54 % of the respondent enterprises had a supply strategy. The total supply cost was on average 60 % of firms' turnover. Centralisation of PSM and outsourcing of logistics will increase in Finnish medium-sized enterprises. The findings point out that Finnish medium-sized enterprises had strategical features of PSM. However, Finnish firms have not concentrated on making strategies that relate to PSM. The elements that explain the existence of a supply strategy could be found in this study. It can be concluded from this study that there is an advantageous base for the development of strategic PSM, because nearly all the enterprises were of the opinion that PSM capabilities have an effect on business success. When reviewing the organisational capabilities, the five most important development elements were supplier relationships, both operational and strategic processes, time management, and personnel's competence. Training in internationalisation, strategic management, and communication could help to improve competences of PSM personnel.

Assessment of purchasing maturity in spare parts supply chain

To describe the change of purchasing moving from administrative to strategic function academics have put forward maturity models which help practitioners to compare their purchasing activities to industry top performers and best practices. However, none of the models aim to distinguish the purchasing maturity from the after-sales point of view, even though after-sales activities are acknowledged as a relevant source of revenue, profit and competitive advantage in most manufacturing firms. The maturity of purchasing and supply management practices have a large impact to the overall performance of the spare parts supply chain and ultimately to the value creation and relationship building for the end customer. The research was done as a case study for a European after-sales organization which is part of a globally operating industrial firm specialized in heavy machinery. The study mapped the current state of the purchasing practices in the case organization and also distinguished the relevant areas for future development. The study was based on the purchasing maturity model developed by Schiele (2007) and investigated also how applicable is the maturity model in the spare parts supply chain context. Data for the assessment was gathered using five expert interviews inside the case organization and other parties involved in the company’s spare parts supply chain. Inventory management dimension was added to the original maturity model in order to better capture the important areas in a spare parts supply chain. The added five questions were deduced from the spare parts management literature and verified as relevant areas by the case organization’s personnel. Results indicate that largest need for development in the case organization are: better collaboration between sourcing and operative procurement functions, use of installed base information in the spare parts management, training plan development for new buyers, assessment of aligned KPI’s between the supply chain parties and better defining the role of after-sales sourcing. The purchasing maturity model used in this research worked well in H&R Leading, Controlling and Inventory Management dimensions. The assessment was more difficult to conduct in the Supplier related processes, Process integration and Organizational structure –dimensions, mainly because the assessment in these sections would for some parts require more company-wide assessment. Results indicate also that the purchasing maturity model developed by Schiele (2007) captures the relevant areas in the spare parts supply as well.

Designing of Balanced Performance Measurement System to Purchasing Process

The performance measurement produces information about the operation of the business process. On the basis of this information performance of the company can be followed and improved. Balanced performance measurement system can monitor performance of several perspectives and business processes can be led according to company strategy. Major part of the costs of a company is originated from purchased goods or services are an output of the buying process emphasising the importance of a reliable performance measurement of purchasing process. In the study, theory of balanced performance measurement is orientated and framework of purchasing process performance measurement system is designed. The designed balanced performance measurement system of purchasing process is tested in case company paying attention to the available data and to other environmental enablers. The balanced purchasing performance measurement system is tested and improved during the test period and attention is paid to the definition and scaling of objectives. Found development initiatives are carried out especially in the scaling of indicators. Finally results of the study are evaluated, conclusions and additional research areas proposed.

Adoption of electronic commerce tools in business procurement:enhanced buying center structure and processes

Modern procurement is being shifted from paper-based, people-intensive buying systems toward electronic-based purchase procedures that rely on Internet communications and Web-enhanced buying tools. Develops a typology of e-commerce tools that have come to characterize cutting-edge industrial procurement. E-commerce aspects of purchasing are organized into communication and transaction tools that encompass both internal and external buying activities. Further, a model of the impact of e-commerce on the structure and processes of an organization's buying center is developed. The impact of the changing buying center on procurement outcomes in terms of efficiency and effectiveness is also analyzed. Finally, implications for business-to-business marketers and researchers are discussed.

Geochemistry Of Acid Mine Drainage From A Coal Mining Area And Processes Controlling Metal Attenuation In Stream Waters, Southern Brazil.

Acid drainage influence on the water and sediment quality was investigated in a coal mining area (southern Brazil). Mine drainage showed pH between 3.2 and 4.6 and elevated concentrations of sulfate, As and metals, of which, Fe, Mn and Zn exceeded the limits for the emission of effluents stated in the Brazilian legislation. Arsenic also exceeded the limit, but only slightly. Groundwater monitoring wells from active mines and tailings piles showed pH interval and chemical concentrations similar to those of mine drainage. However, the river and ground water samples of municipal public water supplies revealed a pH range from 7.2 to 7.5 and low chemical concentrations, although Cd concentration slightly exceeded the limit adopted by Brazilian legislation for groundwater. In general, surface waters showed large pH range (6 to 10.8), and changes caused by acid drainage in the chemical composition of these waters were not very significant. Locally, acid drainage seemed to have dissolved carbonate rocks present in the local stratigraphic sequence, attenuating the dispersion of metals and As. Stream sediments presented anomalies of these elements, which were strongly dependent on the proximity of tailings piles and abandoned mines. We found that precipitation processes in sediments and the dilution of dissolved phases were responsible for the attenuation of the concentrations of the metals and As in the acid drainage and river water mixing zone. In general, a larger influence of mining activities on the chemical composition of the surface waters and sediments was observed when enrichment factors in relation to regional background levels were used.

Construction Of A Manual Of Work Processes And Techniques From Centro De Dispensação De Medicamentos De Alto Custo (cedmac), Hospital De Clínicas, Unicamp.

The Centers for High Cost Medication (Centros de Medicação de Alto Custo, CEDMAC), Health Department, São Paulo were instituted by project in partnership with the Clinical Hospital of the Faculty of Medicine, USP, sponsored by the Foundation for Research Support of the State of São Paulo (Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP) aimed at the formation of a statewide network for comprehensive care of patients referred for use of immunobiological agents in rheumatological diseases. The CEDMAC of Hospital de Clínicas, Universidade Estadual de Campinas (HC-Unicamp), implemented by the Division of Rheumatology, Faculty of Medical Sciences, identified the need for standardization of the multidisciplinary team conducts, in face of the specificity of care conducts, verifying the importance of describing, in manual format, their operational and technical processes. The aim of this study is to present the methodology applied to the elaboration of the CEDMAC/HC-Unicamp Manual as an institutional tool, with the aim of offering the best assistance and administrative quality. In the methodology for preparing the manuals at HC-Unicamp since 2008, the premise was to obtain a document that is participatory, multidisciplinary, focused on work processes integrated with institutional rules, with objective and didactic descriptions, in a standardized format and with electronic dissemination.

Agrin And Perlecan Mediate Tumorigenic Processes In Oral Squamous Cell Carcinoma.

Oral squamous cell carcinoma is the most common type of cancer in the oral cavity, representing more than 90% of all oral cancers. The characterization of altered molecules in oral cancer is essential to understand molecular mechanisms underlying tumor progression as well as to contribute to cancer biomarker and therapeutic target discovery. Proteoglycans are key molecular effectors of cell surface and pericellular microenvironments, performing multiple functions in cancer. Two of the major basement membrane proteoglycans, agrin and perlecan, were investigated in this study regarding their role in oral cancer. Using real time quantitative PCR (qRT-PCR), we showed that agrin and perlecan are highly expressed in oral squamous cell carcinoma. Interestingly, cell lines originated from distinct sites showed different expression of agrin and perlecan. Enzymatically targeting chondroitin sulfate modification by chondroitinase, oral squamous carcinoma cell line had a reduced ability to adhere to extracellular matrix proteins and increased sensibility to cisplatin. Additionally, knockdown of agrin and perlecan promoted a decrease on cell migration and adhesion, and on resistance of cells to cisplatin. Our study showed, for the first time, a negative regulation on oral cancer-associated events by either targeting chondroitin sulfate content or agrin and perlecan levels.

In vitro Microfluidic Model For The Study Of Vaso-occlusive Processes.

Vaso-occlusion, responsible for much of the morbidity of sickle-cell disease, is a complex multicellular process, apparently triggered by leukocyte adhesion to the vessel wall. The microcirculation represents a major site of leukocyte-endothelial interactions and vaso-occlusive processes. We have developed a biochip with subdividing interconnecting microchannels that decrease in size (40 μm to 10 μm in width), for use in conjunction with a precise microfluidic device, to mimic cell flow and adhesion through channels of sizes that approach those of the microcirculation. The biochips were utilized to observe the dynamics of the passage of neutrophils and red blood cells, isolated from healthy and sickle-cell anemia (SCA) individuals, through laminin or endothelial adhesion molecule-coated microchannels at physiologically relevant rates of flow and shear stress. Obstruction of E-selectin/intercellular adhesion molecule 1-coated biochip microchannels by SCA neutrophils was significantly greater than that observed for healthy neutrophils, particularly in the microchannels of 40-15 μm in width. Whereas SCA red blood cells alone did not significantly adhere to, or obstruct, microchannels, mixed suspensions of SCA neutrophils and red blood cells significantly adhered to and obstructed laminin-coated channels. Results from this in vitro microfluidic model support a primary role for leukocytes in the initiation of SCA occlusive processes in the microcirculation. This assay represents an easy-to-use and reproducible in vitro technique for understanding molecular mechanisms and cellular interactions occurring in subdividing microchannels of widths approaching those observed in the microvasculature. The assay could hold potential for testing drugs developed to inhibit occlusive mechanisms such as those observed in SCA and thrombotic diseases.
