Gestão de stocks aplicada a uma instituição de saúde privada

A gestão de stocks tem-se tornado uma ferramenta fundamental na racionalização de custos das empresas permitindo uma maior eficiência operacional. Os modelos de gestão de stocks procuram ajudar a determinar as quantidades a encomendar e quando encomendar, com um custo total de aprovisionamento mínimo. Este trabalho visa o estudo da gestão de stocks, dos modelos existentes e a aplicação de um deles num prestador de saúde, em particular, na área da imagiologia. Neste estudo optou-se por efectuar a classificação ABC dos produtos e posteriormente procurou-se definir o modelo de gestão de stocks que melhor se adeqúe à realidade empresarial em estudo de modo a manter o nível de stock correcto associado a um menor custo. Optou-se pelo modelo de revisão periódica de stocks que permite efectuar a encomenda sempre com o mesmo intervalo de tempo e efectuar ajustes nas quantidades necessárias. Com base nos dados fornecido efectuou-se uma previsão da procura e assim definiram-se as quantidades a encomendar, bem como o stock de segurança necessário. Implementaram-se as quantidades e o stock de segurança e efectuou-se uma avaliação dos resultados obtidos e analisou-se o impacto da gestão de stocks no prestador de saúde.

Evaluating vehicle painting plans in an automobile assembly plant using an integrated AHP-PROMETHEE approach

The painting activity is one of the most complex and important activities in automobile manufacturing. The inherent complexity of the painting activity and the frequent need for repainting usually turn the painting process into a bottleneck in automobile assembly plants, which is reflected in higher operating costs and longer overall cycle times. One possible approach for optimizing the performance of the paint shop is to improve the efficiency of the color planning. This can be accomplished by evaluating the relative merits of a set of vehicle painting plans. Since this problem has a multicriteria nature, we resort to the multicriteria decision analysis (MCDA) methodology to tackle it. A recent trend in the MCDA field is the development of hybrid approaches that are used to achieve operational synergies between different methods. Here we apply, for the first time, an integrated approach that combines the strengths of the analytic hierarchy process (AHP) and the Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE), aided by Geometrical Analysis for Interactive Aid (GAIA), to the problem of assessing alternative vehicle painting plans. The management of the assembly plant found the results of value and is currently using them in order to schedule the painting activities such that an enhancement of the operational efficiency of the paint shop is obtained. This efficiency gain has allowed the management to bid for a new automobile model to be assembled at this specific plant.

The implementation of an Enterprise Geographical Information System to support Cadastre and Expropriation activities.

The processes of mobilization of land for infrastructures of public and private domain are developed according to proper legal frameworks and systematically confronted with the impoverished national situation as regards the cadastral identification and regularization, which leads to big inefficiencies, sometimes with very negative impact to the overall effectiveness. This project report describes Ferbritas Cadastre Information System (FBSIC) project and tools, which in conjunction with other applications, allow managing the entire life-cycle of Land Acquisition and Cadastre, including support to field activities with the integration of information collected in the field, the development of multi-criteria analysis information, monitoring all information in the exploration stage, and the automated generation of outputs. The benefits are evident at the level of operational efficiency, including tools that enable process integration and standardization of procedures, facilitate analysis and quality control and maximize performance in the acquisition, maintenance and management of registration information and expropriation (expropriation projects). Therefore, the implemented system achieves levels of robustness, comprehensiveness, openness, scalability and reliability suitable for a structural platform. The resultant solution, FBSIC, is a fit-for-purpose cadastre information system rooted in the field of railway infrastructures. FBSIC integrating nature of allows: to accomplish present needs and scale to meet future services; to collect, maintain, manage and share all information in one common platform, and transform it into knowledge; to relate with other platforms; to increase accuracy and productivity of business processes related with land property management.

Value added logistics in supply and demand chain. Smile. Part 2. eBusiness in a service business. Case: A maintenance and operations network in forest industry

VVALOSADE is a research project of professor Anita Lukka's VALORE research team in the Lappeenranta University of Technology. The VALOSADE includes the ELO technology program of Tekes. SMILE is one of four subprojects of the VALOSADE. The SMILE study focuses on the case of the company network that is composed of small and micro-sized mechanical maintenance service providers and forest industry as large-scale customers. The basic principle of the SMILE study is the communication and ebusiness in supply and demand networks. The aim of the study is to develop ebusiness strategy, ebusiness model and e-processes among the SME local service providers, and onthe other hand, between the local service provider network and the forest industry customers in a maintenance and operations service business. A literature review, interviews and benchmarking are used as research methods in this qualitative case study. The first SMILE report, 'Ebusiness between Global Company and Its Local SME Supplier Network', concentrated on creating background for the SMILE study by studying general trends of ebusiness in supply chains and networks of different industries. This second phase of the study concentrates on case network background, such as business relationships, information systems and business objectives; core processes in maintenance and operations service network; development needs in communication among the network participants; and ICT solutions to respond needs in changing environment. In the theory part of the report, different ebusiness models and frameworks are introduced. Those models and frameworks are compared to empirical case data. From that analysis of the empirical data, therecommendations for the development of the network information system are derived. In process industry such as the forest industry, it is crucial to achieve a high level of operational efficiency and reliability, which sets up great requirements for maintenance and operations. Therefore, partnerships or strategic alliances are needed between the network participants. In partnerships and alliances, deep communication is important, and therefore the information systems in the network also are critical. Communication, coordination and collaboration will increase in the case network in the future, because network resources must be optimised to improve competitive capability of the forest industry customers and theefficiency of their service providers. At present, ebusiness systems are not usual in this maintenance network. A network information system among the forest industry customers and their local service providers actually is the only genuinenetwork information system in this total network. However, the utilisation of that system has been quite insignificant. The current system does not add value enough either to the customers or to the local service providers. At present, thenetwork information system is the infomediary that share static information forthe network partners. The network information system should be the transaction intermediary, which integrates internal processes of the network companies; the network information system, which provides common standardised processes for thelocal service providers; and the infomediary, which share static and dynamic information on right time, on right partner, on right costs, on right format and on right quality. This study provides recommendations how to develop this system in the future to add value to the network companies. Ebusiness scenarios, vision, objectives, strategies, application architecture, ebusiness model, core processes and development strategy must be considered when the network information system will be developed in the next development step. The core processes in the case network are demand/capacity management, customer/supplier relationship management, service delivery management, knowledge management and cash flow management. Most benefits from ebusiness solutions come from the electrifying of operational level processes, such as service delivery management and cash flow management.

Absorbex®-linjan tehokkuuden parantaminen

Laminating Papers Oy:n PK1 Absorbex®-linjan lajivalikoima on erittäin suuri. Johtuen laajasta lajivalikoimasta ja pienestä keskimääräisestä tilauskoosta, tehdään PK1:llä useita lajinvaihtoja päivässä. Diplomityön tavoitteena oli parantaa tehokkuutta rationalisoimalla lajivalikoimaa ja kehittämällä lajinvaihtoprosessia. Työn kirjallisuusosassa esitettiin Absorbex®-paperin valmistus, sekä paperilta vaaditut laatuominaisuudet. Lisäksi esitettiin paperin impregnointi ja loppukäyttö laminaatin runkopaperina. Kirjallisuusosassa käsiteltiin myös paperikonelinjan tuottavuutta ja tehokkuutta, sekä niiden yhteyttä kannattavuuteen, laatuun ja Laminating Papers Oy:n strategian toteuttamiseen. Lisäksi käsiteltiin paperikoneen tehokkuutta ja sen mittaamista hyötysuhteilla.Kokeellisessa osassa tehtiin alustava selvitys PK1:n kokonaishyötysuhteeseen vaikuttavista tekijöistä. Selvityksen mukaan PK1:n kokonaishyötysuhde on heikko johtuen suuresta hylyn määrästä. Hylky muodostuu pääasiassa lajinvaihtohylystä ja pituusleikkauksen leveyshäviöstä. Kokonaishyötysuhteen parantamiseksi pitää lajivalikoimaa saada pienemmäksi. Lajivalikoiman rationalisoimiseksi poistettiin valikoimasta lajit, joita asiakas ei enää tilaa, sekä pyrittiin yhdistämään laatuominaisuuksiltaan lähellä toisiaan olevia lajeja. Lisäksi tuotannollisesti hankalat lajit pyrittiin poistamaan tai muuttamaan laatuspesifikaatiota edulliseksi. Lajivalikoiman hallitsemiseksi tulevaisuudessa kehitettiin työohje lajien rationalisoinnista ja määriteltiin PK1:n ihanne lajivalikoiman laatualueet. Lajinvaihto prosessia tutkittiin automaattisen lajinvaihdon ja operaattorien toiminnan osalta. Automaattisen lajinvaihdon toimintakyky selvitettiin erityisessä kartoitustutkimuksessa ja operaattorien suoritukselle pyrittiin löytämään paras mahdollinen toimitapa. Lajivalikoiman rationalisoinnissa on suuri potentiaali tehokkuuden parantamiseksi. Ihanne lajivalikoimaan päästäessä saadaan pelkästään lajinvaihtohylyn vähenemisen kautta kokonaishyötysuhdetta nostettua noin kaksi prosenttiyksikköä. Potentiaalin hyödyntäminen vaatii pitkäjänteistä yhteistyötä ja säännöllistä seurantaa tuotannon, teknisen asiakaspalvelun, myynnin ja markkinoinnin kesken. Automaattisen lajinvaihdon häiriötön toiminta edellyttää huolellista käyttöä ja säännöllistä ylläpitoa. Lajinvaihto voidaan suorittaa tehokkaasti käyttämällä aina parhaiksi havaittuja toimitapoja.

Reconstruction and analysis of surface variation using photometric stereo

In many industrial applications, accurate and fast surface reconstruction is essential for quality control. Variation in surface finishing parameters, such as surface roughness, can reflect defects in a manufacturing process, non-optimal product operational efficiency, and reduced life expectancy of the product. This thesis considers reconstruction and analysis of high-frequency variation, that is roughness, on planar surfaces. Standard roughness measures in industry are calculated from surface topography. A fast and non-contact method to obtain surface topography is to apply photometric stereo in the estimation of surface gradients and to reconstruct the surface by integrating the gradient fields. Alternatively, visual methods, such as statistical measures, fractal dimension and distance transforms, can be used to characterize surface roughness directly from gray-scale images. In this thesis, the accuracy of distance transforms, statistical measures, and fractal dimension are evaluated in the estimation of surface roughness from gray-scale images and topographies. The results are contrasted to standard industry roughness measures. In distance transforms, the key idea is that distance values calculated along a highly varying surface are greater than distances calculated along a smoother surface. Statistical measures and fractal dimension are common surface roughness measures. In the experiments, skewness and variance of brightness distribution, fractal dimension, and distance transforms exhibited strong linear correlations to standard industry roughness measures. One of the key strengths of photometric stereo method is the acquisition of higher frequency variation of surfaces. In this thesis, the reconstruction of planar high-frequency varying surfaces is studied in the presence of imaging noise and blur. Two Wiener filterbased methods are proposed of which one is optimal in the sense of surface power spectral density given the spectral properties of the imaging noise and blur. Experiments show that the proposed methods preserve the inherent high-frequency variation in the reconstructed surfaces, whereas traditional reconstruction methods typically handle incorrect measurements by smoothing, which dampens the high-frequency variation.

Change of Electricity Distribution Industry: Drivers and Opening Business Opportunities

As a result of the recent regulatory amendments and other development trends in the electricity distribution business, the sector is currently witnessing radical restructuring that will eventually impact the business logics of the sector. This report represents upcoming changes in the electricity distribution industry and concentrates on the factors that are expected to be the most fundamental ones. Electricity network companies nowadays struggle with legislative and regulatory requirements that focus on both the operational efficiency and the reliability of electricity distribution networks. The forces that have an impact on the distribution network companies can be put into three main categories that define the transformation at a general level. Those are: (1) a requirement for a more functional marketplace for energy, (2) environmental aspects (combating climate change etc.), and (3) a strongly emphasized requirement for the security of energy supply. The first point arises from the legislators’ attempt to increase competition in electricity retail markets, the second one concerns both environmental protection and human safety issues, and the third one indicates societies’ reduced willingness to accept interruptions in electricity supply. In the future, regulation of electricity distribution business may lower the threshold for building more weather-resistant networks, which in turn means increased underground cabling. This development pattern is reinforced by tightening safety and environmental regulations that ultimately make the overhead lines expensive to build and maintain. The changes will require new approaches particularly in network planning, construction, and maintenance. The concept for planning, constructing, and maintaining cable networks is necessary because the interdependencies between network operations are strong, in other words, the nature of the operation requires a linkage to other operations.
