Assuming that all unmet demand is fully lost, we begin our study by confining the sales lever to be price only, that is, z = p , and ignoring the cost for executing the sales lever. Given a stationary (s, S, p) policy, we find that the profit function for the lost-sales case exhibits the same structure as the one for the backlogging case. We further show that the relaxed assumption on the news-vendor type profit function can also be satisfied by a broad class of demand function. We can therefore extend the optimizing algorithm and the optimality analysis developed earlier to the lost-sales case. We further demonstrate that the results can be extended to the general sales lever decisions. / Assuming that unmet demand is fully backlogged, a newsvendor-type profit function which is defined as the resulting expected one-period profit with sales lever being optimized for every inventory level, fails to be unimodal. By assuming the newsvendor-type profit function to have a finite number of local maxima, we develop an efficient algorithm for finding the optimal ( s, S, z) policy with the long-run average profit derived by the renewal theory. We further identify the conditions under which the (s, S, z) policy is globally optimal. / Issues on the interfaces between operations management and marketing research have attracted much attention recently. The developments integrating marketing decisions into inventory management are not only of academic interest, but also of practical importance. With uncertain demand, this research studies the joint determination of inventory and sales lever decisions such as price, incentives to salesforce, and short-term promotions, or a combination of them. / We consider a single-item, periodic-review system with the objective of maximizing the long-run average profit over an infinite planning horizon. Demand in a period is a non-negative, discrete random variable with its distribution dependent on the sales lever chosen for the period. A replenishment order can be placed at the beginning of a period incurring both fixed and variable ordering costs. The sales lever is determined jointly, and its execution may incur possible cost, for example, promotion cost. For such a model, we take particular interest in a so-called (s, S, z) policy, which operates as follows: whenever the inventory level falls to or below s, an order is placed to bring it up to S; when the inventory level is above s, no order is issued; the choice of sales lever z depends on the inventory level. / We finally conduct an extensive numerical study for both the backlogging and lost-sales cases. We compare the benefits of the dynamic sales lever strategy with those of the semi-dynamic as well as the static sales lever strategy, and find that the profit gains are significant. By sensitivity analysis, we bring out the impact of cost parameters on the optimal solutions. / Wei Ying. / "December 2006." / Adviser: Youhua Frank Chen. / Source: Dissertation Abstracts International, Volume: 68-09, Section: A, page: 3961. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 125-131). / Electronic reproduction.

Humans have affected the Swedish forests for a long time, mainly through agriculture and forestry. Since the beginning of the 20th century, a lot of changes have taken place in forest policy, which have affected the structures of our forests, such as tree age, size and species distributions. By using information from different types of historical data, we can increase our understanding of the earlier structures of forests and how to manage them in the future. This study investigated changes in annual growth and changes in age, diameter, height and tree species distribution in the forests of Östergötland from year 1927 to the period 1983-2017, using data from the Swedish National Forest Inventory. Six tree species where used, Picea spp, Pinus spp, Quercus robur, Betula spp, Alnus spp and Populus tremula. There was an increase in the proportion of Picea spp, and a decrease in the proportion of Pinus spp since 1927. The proportion of deciduous trees also increased but not as much. Interestingly, the proportion of Betula spp had fallen since 1927, but the now larger proportion of young trees indicate that the proportion of Betula spp is increasing again. Q. robur, P. tremula, Picea spp and Pinus spp also had a larger proportion of younger trees in the more recent period. There was a significantly higher proportion of tall trees during the latter period for all tree species. For growth rate in width, the results varied among tree species. For Betula spp it had decreased and for Q. robur it had increased. For the coniferous trees there was hardly any difference between the periods. Overall, the results show that Östergötland's forests have been influenced by forestry and increased ungulate populations since the first inventory 1927 and that there have been changes in the composition of the forests. / Människan har länge påverkat de svenska skogarna. Sedan 1900-talets början har en hel del förändringar skett inom skogspolitiken, vilket har påverkat bland annat skogarnas ålder- och storleksfördelning, samt trädslagsfördelning. Genom att använda information från olika typer av historiska data kan vi öka vår förståelse om hur skogar såg ut förr och vad som har påverkat dem. Denna studie undersökte skillnader i tillväxt, höjd-och diameterfördelning, samt åldersfördelning i Östergötlands skogar från år 1927 till perioden 1983–2017, med hjälp av data från riksskogstaxeringen. Sex trädslag användes; gran (Picea spp), tall (Pinus spp), ek (Quercus robur), björk (Betula spp), al (Alnus spp) och asp (Populus tremula). En kraftig ökning av andelen gran hade skett sedan 1927, medan andelen tall hade minskat. För lövträden hade det endast skett en liten ökning i andel. Intressant var också att andelen björk hade minskat sedan 1927 och att andelen björkar yngre än 50 år var större den senare perioden, vilket indikerar att björkens andel kan vara på väg att öka igen. Ek, asp, gran och tall hade också en större andel yngre träd under den senare perioden. För alla trädslag fanns det en betydligt mindre andel höga träd år 1927. För årlig tillväxt i bredd varierade resultaten trädslagen emellan. För björk hade årsringsbredden minskat sedan 1927, medan den hade ökat för ek. För barrträden var det knappt någon skillnad mellan perioderna. Resultaten visar att Östergötlands skogar har påverkats mycket av skogsbruket, samt klövviltsbete, sedan 1927 och att det har skett flera strukturella förändringar i skogarnas sammansättning.

The aim of this dissertation thesis is to compile a systematic methodical approach for fixed assets as a national methodology. It focuses on stocks, consumption of fixed capital and capital services. The thesis is divided into three parts and six chapters. Chapter one and chapter two are used as a general theoretical base for chapters 3 to 5. Chapter 3 is based on a standard approach to the perpetual inventory method (PIM) as it is used in the Czech Republic. Chapter 4 is devoted to capital services and to an alternative approach to PIM. It is not used in the Czech Republic until now. Estimates are an integral part of the chapter. Chapter 5 describes capital services for other non-market producers, both methodology and estimates are covered. The impact of the change of the so-called cost method used for the estimates of output of other non-market producers on gross domestic product is calculated. The change consists in the substitution of consumption of fixed capital by capital services. Chapter 6 summarizes and explains the consequences in terms of national accounts.

Cyclical component of aggregate net inventory investment in Czech republic between I.quarter 1996 and IV.quarter 2010 can be described by Production smoothing model, which says, that it is more advantageous for firms to absorb shocks of their product demand into inventories than to adjust their production permanently. This statement stands on a discovery, that cyclical component of net inventory investment is negativelly corralated with cyclical component of final sales and at the same time variability of cyclical component of final sales is higher than cyclical component of production (GDP). Although it is not possible to expect that every firm in the economy will behave according to this model, it seems, with respect to the analysis, that the cost of adjustment is one of the most important factors considered by firms within their optimalization problem.

This thesis deals with the logistics of WISSA, spol. s r.o. The aim of this thesis is the characterization of the individual areas of the company's logistics. It also summarizes the legislative and contractual requirements, which the company must follow. I describe the company's system of transportation, warehousing, inventory management, as well as the flow of logistical information. I also note the tools that enable the function of each area. I am also looking for problems that arise in the company's logistics and I am trying to provide solutions for them. Using of various analysis and methods - such as the ABC method or the method of inventory management, I suggest improvements for corresponding areas of logistics. At the request of company management, which also represents the main user of the results of this thesis, I deal with several decision problems related to logistics. Specifically, I am providing them with information for the choice concerning the benefits of changing the location of the company's warehouse or decisions about the choice of transportation methods.

The thesis deals with minimizing of the inventory of finished products in the ceramic industry. To reduce inventory the ABC and XYZ analysis was used for the sorting of products into the groups and particular ways were suggested to reduce inventories of finished products. In the theoretical part are described the theoretical assumptions for inventory management issues such as costs, demand, or different methods of inventory management. Then the technological process of production of ceramic tiles follows. In the practical part, entire knowledge of the theory is applied to the problems of ceramic tiles production in LASSELSBERGER, Ltd. It concerns specifically about 1284 products analyzed by using ABC and XYZ methods. Proposed methods and their effect on saving of storage space (storage space saving) were compared afterwards. The result of the work is a comprehensive product portfolio analysis of LASSELSBERGER, Ltd. indicating to company management, which economy measures will ensure the highest costs saving.

Os objetivos deste trabalho foram avaliar a situação da arborização viária em dois bairros de Americana/SP, apresentar dados que possam servir de base para seu plano diretor de arborização urbana, escolher espécies para plantio nas calçadas, junto à população local, e colaborar no envolvimento dos moradores na solução dos freqüentes problemas relacionados à educação ambiental. Na primeira fase, foi feito um inventário das árvores existentes, analisando as espécies mais freqüentes, suas condições e as infra-estruturas que as envolviam. Na segunda fase realizou-se entrevistas, com aplicação de questionário aos moradores, que não tinham plantas nas calçadas. O questionário era acompanhado de pranchas, com fotos das espécies selecionadas e características da rua em questão. Foram encontradas 2.551 árvores plantadas, sendo a maioria de espécies exóticas, em 76 espécies diferentes, com maiores freqüências da Murraya exótica (falsa murta) com 18,42%, Ligustrum lucidum (ligustro) com 16,50% e Licania tomentosa (oiti) com 12,47%. Na falsa murta verificou-se baixa porcentagem de podas drásticas, em V e L, porém a porcentagem de podas de condução e topiaria foram marcantes. A maioria das podas foi motivada pela presença da fiação elétrica, e o ligustro, canelinha e sete copas, apresentaram as maiores porcentagens. O ligustro, seguido de sibipiruna e sete copas, apresentaram raízes afetando estruturas urbanas, como, também, maiores porcentagens de área livre insuficiente. A falsa murta vem substituindo estas árvores, evidenciando tal preferência pela população e órgãos públicos, o que preocupa vários técnicos. Em 485 casas visitadas, foram entrevistados 247 moradores, 162 casas não tinham moradores e, em 55 casas, os moradores não quiseram atender. Dos moradores entrevistados, 70,04% já tiveram uma árvore plantada na calçada e, 79,76% rejeitaram o plantio em frente às suas casas. Mais da metade dos moradores entrevistados (61,13%) desconhece o responsável pela arborização urbana e a maioria (67,21%) não reconhece os benefícios que a calçada verde pode fornecer. A ordem de preferência foi de 54,49% para arbustos, 29,55% para árvores, sendo que 8,91% não opinaram e 4,05% disseram não gostar de planta alguma. As espécies, Stifftia crysantha Mikan e, Lagerstroemia indica L. foram as mais votadas pelos moradores. Diante deste panorama, constata-se que muito há que se fazer em prol da melhoria da arborização nos bairros pesquisados e a participação da comunidade é fundamental em contribuir na qualidade, tanto da pesquisa, como no plano diretor da arborização urbana. / This work aimed at evaluating the situation of urban forestry in two districts of Americana city (Brazil), showing data that may be useful as a fundament for an urban forestry master plan. Additionally, we intended to choose plant species for pavements together with the local population and to collaborate to involve the inhabitants to find solutions for the frequent problems associated to environment education. During the first phase of the project, an inventory of the existing trees was prepared, analyzing the more common species, their conditions and the infrastructure around them. For the second phase, interviews were carried out to the dwellers that did not have plants in their pavements. The questionnaire came along boards with pictures of the selected species and the characteristics of their streets. In the area studied, 2,551 trees planted of 76 different species were counted, being the majority of exotic species, with the most frequents: Murraya exótica (Rutaceae: jasmine) with 18.42%, Ligustrum lucidum (Oleaceae: privet) with 16.50% and Licania tomentosa (Crhysobalanaceae: oiti) with 12.47%. A low percentage of drastic pruning, in “V” or “L”, was observed in privet shrubs; however, the management and shaping prunings were remarkable. The majority of prunings were motivated by the electric wires, and privet, canelinha and sete copas showed the highest rates. Privet, followed by sibipiruna and sete copas, showed roots affecting urban structures, as well as the highest rates of insufficient free area. These species are being replaced by jasmine, showing the preference of the population and public organs, which worries several experts. From the 485 houses visited, 247 dwellers were interviewed, 162 houses did not have residents and in 55 houses the owners did not want to answer the questionnaire. Of the dwellers interviewed, 70.04% already had a tree in the pavement and 79.76% rejected a tree in front of their houses. More than a half of the dwellers interviewed (61.13%) did not know the responsible for urban forestry and the majority of them (67.21%) did not know the benefits of having a green in their pavement. The order of preference was 54.49% for shrubs and 29.55% for trees; 8.91% did not opine and 4.05% said not to like any kind of plant. The species Stifftia crysantha Mikan and, Lagerstroemia indica L. were the most voted by the dwellers. In front of this panorama, one can notice that many there is must be done to improve the forestry in the districts studied and that the communitarian participation is something that would help the quality, not only of the inquiry by also of a urban forestry master plan.

Iniciativas no sentido de identificar o patrimônio geológico brasileiro com base em estratégias de Geoconservação vêm crescendo ao longo dos anos, em várias regiões do país. O presente estudo visa contribuir para a compreensão da trajetória e abrangência destas pesquisas que, apesar de importantes para a Geoconservação brasileira, são numericamente pouco expressivas devido a quatro fatores preponderantes: i) por serem pontuais; ii) devido à grande extensão do território brasileiro; iii) pela Geoconservação ainda ser uma ciência recente, sendo as pesquisas nacionais representativas apenas a partir de 2010; e iv) ainda que em número crescente, são poucos os pesquisadores envolvidos com a temática. Quanto maior o número de pesquisas realizadas sobre inventários do patrimônio geológico, melhor para a divulgação da Geoconservação no contexto acadêmico, intensificando o envolvimento de geocientistas com a temática, além do diálogo e da reflexão entre os diversos grupos de trabalho atuantes. Como parte destas iniciativas, métodos de inventário e avaliação quantitativa de sítios geológicos foram aplicados no município de Cananeia. O inventário resultou em doze sítios que representam contextos geológicos do Terreno Paranaguá, das intrusões alcalinas e básicas do Cretáceo, das variações do nível do mar no Quaternário e de processos atuais da dinâmica costeira. Onze geossítios foram definidos: 1) Metassedimentos da Praia do Pereirinha e intrusões alcalinas, 2) Metassedimentos da Ponta do Itacuruçá, 3) Serra do Itapitangui, 4) Sienito da Praia do Foles, 5) Granito Cambriú, 6) Granito Peralcalino do Ariri, 7) Granito milonítico do Ariri, 8) Intrusão diabásica do Pindaúba, 9) Intrusão alcalina do Morro de São João, 10) Terraço marinho pleistocênico do Mar Pequeno e 11) Processo erosivo dos depósitos litorâneos da Enseada da Baleia. Apenas um sítio da geodiversidade foi identificado, representado pelo Terraços de abrasão marinha da Ilha do Cardoso. A avaliação quantitativa foi feita por meio da plataforma de cadastro nacional GEOSSIT, do Serviço Geológico do Brasil (CPRM). Os parâmetros avaliados para cada geossítio relacionam-se ao Valor Científico, Risco de Degradação e Potencial de Uso Educativo e Turístico. Em conjunto, estes dados pretendem contribuir para a reflexão acerca da situação atual da prática da Geoconservação no Brasil e para auxiliar iniciativas de valorização, divulgação e gestão da geodiversidade. / Initiatives to identify Brazilian geological heritage based on Geoconservation strategies have been growing over the years in several regions of the country. The present study aims to contribute to the understanding of the trajectory and comprehensiveness of these researches that, although important for the Brazilian Geoconservation, are numerically little expressive due to four preponderant factors: i) being punctual; ii) due to the great extent of the Brazilian territory; iii) Geoconservation is still a recent science, and national surveys are only representative from 2010; and iv) although in increasing numbers, few researchers are involved with the subject. The greater the number of researches carried out on geological heritage inventories, the better for the dissemination of Geoconservation in the academic context, intensifying the involvement of geoscientists with the theme, as well as dialogue and reflection among the various working groups. As part of these initiatives, methods of inventory and quantitative evaluation of geological sites were applied in the municipality of Cananeia. The inventory resulted in twelve sites representing the geological contexts of the Paranaguá Terrain, the alkaline and basic intrusions of the Cretaceous, the variations of sea level in the Quaternary and current processes of the coastal dynamics. Eleven geosites were defined: 1) Pereirinha Beach metassediments and alkaline intrusions, 2) Metassediments of Ponta do Itacuruçá, 3) Serra do Itapitangui, 4) Sienito of Praia do Foles, 5) Cambriú Granite, 6) Peralcalino Granite of Ariri, 7) Ariri milonitic granite, 8) Pindaúba intrusion, 9) Alkaline intrusion of Morro de São João, 10) Pleistocene marine terrace of the Mar Pequeno, and 11) Erosive process of the coastal deposits of the Enseada da Baleia. Only one site of the geodiversity was identified, represented by the Terraces of marine abrasion of the Cardoso Island. The quantitative evaluation was done through the GEOSSIT national cadastre platform from the Geological Survey of Brazil (CPRM). The parameters evaluated for each geosit are related to the Scientific Value, Risk of Degradation and Potential of Educational and Tourist Use. Together, these data intend to contribute to the reflection about the current situation of the practice of Geoconservation in Brazil and to assist initiatives of valorization, diffusion and geodiversity management

O principal propósito deste trabalho é avaliar as principais variáveis que devem ser consideradas no dimensionamento do buffer de componentes de uma empresa que trabalha sob a ótica da Manufatura Enxuta, que devem ser fornecidos a uma célula de manufatura com mix variado de conjuntos similares a serem produzidos. Como mecanismo de validação da investigação, devido ao dinamismo inerente a operação de sistemas de produção com layout célular, foi utilizada a ferramenta Mapeamento de Fluxo de Valor com o apoio de uma estrutura de um software comercial de simulação computacional aplicando o otimizador do aplicativo desenvolvido a partir de um algoritmo genético a fim de contrapor o uso do abastecedor das células com o controle efetivo do nível de inventário do buffer. Como resultado são apresentados diferentes cenários definidos como experimentos tendo como principal fator a variação do tempo de ciclo de abastecimento executado e o fluxo de material como parâmetro inerente a demanda por cada um dos componentes consumidos na operação da célula de manufatura. Através das análises dos resultados foi concluído que os elevados níveis de estoque se tornam ou não necessários dependendo preliminarmente da capacidade de carregamento por ciclo de abastecimento do transportador e o tempo de ciclo necessário para a realização da atividade de ressuprimento. A relevância do tema de pesquisa estudado encontra-se na contribuição pertinente às informações adquiridas in loco na realidade de uma empresa que trabalha sob a ótica da Manufatura Enxuta, no crescente aumento da complexidade dos sistemas produtivos e, consequentemente, da dificuldade de análises mais precisas do impacto que as variáveis de fluxo, como por exemplo, tempo de abastecimento e movimentação, tempo de setup e os respectivos roteiros de fabricação podem causar no desempenho dos processos no chão de fábrica. / The main purpose of this work is to evaluate the main variables that must be considered in the component buffer dimensioning of a company that works with Lean Manufacturing, which to a manufacturing cell should be supplied with a varied mix of similar sets to be produced . As a research validation mechanism, due to the dynamism inherent in the operation of production systems with cell layout, the Value Stream Mapping tool was used with the support of a commercial software simulation structure applying the developed application optimizer from a genetic algorithm in order to counteract the use of the cell supplier with the effective control of the inventory level of the buffer. As a result, different scenarios defined as experiments are presented, the main factor being the variation of the supply cycle time executed and the material flow as a parameter inherent to the demand for each of the components consumed in the manufacturing cell operation. Through the analysis of the results it was concluded that high levels of stock become or not necessary depending on the loading capacity per transport cycle of the conveyor and the cycle time required to perform the resupply activity. The relevance of the studied research theme lies in the relevant contribution to the information acquired locally in the reality of a company that works from the perspective of the Lean Manufacturing, in the increasing complexity of the productive systems and, consequently, of the difficulty of more precise analyzes of the impact that the flow variables, such as supply and handling time, setup time and the respective manufacturing routes, can cause in the process performance on the shop floor.

O município de Bertioga insere-se, geologicamente, no Terreno Serra do Mar, em grande parte coberto por sedimentos cenozoicos e sua história geológica está relacionada aos estágios de evolução do Supercontinente Gondwana até os eventos de variação do nível relativo do mar durante o Quaternário. Além da notável geodiversidade, omunicípio possui extraordinária importância em relação às fortificações militares construídas com materiais pétreos entre os séculos XVI e XX no litoral paulista, pois, dentre as dezoito fortificações inicialmente existentes, restam apenas sete, das quais uma (Forte São João) está nele situado. As restantes (Fortaleza de Santo Amaro da Barra Grande, Fortim da Praia do Góes, Fortaleza de Vera Cruz de Itapema, Forte São Luiz, Fortaleza de Itaipu e Forte dos Andradas), situam-se em Guarujá e Praia Grande. Com base nestes fatos, esta pesquisa foi estruturada de forma a elaborar estratégias de geoconservação para a geodiversidade in situ e ex situ da região. A avaliação da geodiversidade in situ foi feita por meio do inventário de geossítios (com valor científico) e de sítios de geodiversidade (com valor educativo e turístico). Como resultado, foram definidos os seguintes geossítios: Registros tectônicos da Cachoeira do Sertão, Milonitos da Praia de São Lourenço, Gnaisse do Canto do Itaguá, Mirante da Serra do Mar, Terraço Pleistocênico do Rio Itapanhaú, Paleoterraço do Rio Guaratuba, Captura fluvial do Rio Guaratuba e Terraços Marinhos da Praia de Itaguaré. Os sítios de geodiversidade são: Granitos da Praia do Indaiá, Gnaisses da Praia de São Lourenço, Blocos rolados do Rio Itatinga e Granitos da Cachoeira do Guaratuba. A análise da geodiversidade ex situ foi feita de forma a identificar os tipos de pedras utilizadas na construção das fortificações, inferir sobre a provável proveniência destes materiais, avaliar o estado de conservação, reconhecer seu uso atual e apresentar um levantamento histórico-bibliográfico sobre as fortificações remanescentes. Com base nos resultados para a geodiversidade in situ foi possível constatar que os sítios que apresentam maior risco de degradação por atividades antrópicas são aqueles localizados em praias e cachoeiras devido ao grande número de visitantes, enquanto os sítios que possuem baixo risco de degradação são os protegidos por meio das Unidades de Conservação. Por sua vez, os sítios que possuem moderado risco de degradação localizam-se em praias e em áreas não protegidos. Os resultados da geodiversidade ex situ atestam os blocos de pedras utilizadas nas construções são de granitos e gnaisses, rochas provenientes do Terreno Serra do Mar e outras representantes da geodiversidade local. Com base nesses resultados foram elaboradas propostas de gestão, divulgação e valorização para os geossítio e sítio de geodiversidade e propostas de roteiros geoturísticos para as fortificações. Essas propostas oferecem subsídios para as estratégias de geoconservação da geodiversidade in situ e ex situ e visam contribuir com o planejamento territorial de forma a proteger a geodiversidade para esta e para as futuras gerações. / The town of Bertioga is situated, in terms of geology, on the Serra do Maz Terrain, covered to a lazge extent by Cenozoic sediments, and its geological history is related to the stages of evolution of the Gondwana supercontinent up to the relative sea level variation events during the Quaternary. In addition to the outstanding geodiversity, the municipality has extraordinary importance regazding the military fortifications built with stone materials between the XVI and XX centuries on the coast of São Paulo State, considering that, among the eighteen initially existing fortifications, only seven have been preserved, one of which (São João Fort) is located within the city limits. The others (Fortress of Santo Amazo da Barra Grande, Fortress of Praia do Góes, Fortress of Vera Cruz de Itapema, São Luiz Fort, Fortress of Itaipu and Andradas Fort) are located in Guarujá and Praia Grande. Based on these facts, this research was conceived in such a way as to develop geoconservation strategies for the geodiversity in situ and ex situ of the region. The assessment of the geodiversity situ was done through the inventory of geosites (with scientific value) and geodiversity sites (with educational and touristic value). As a result, the following geosites were determined: Tectonic records of Cachoeira do Sertã.o, Mylonites of São Lourenço beach, Gneiss of Canto do Itaguá, Viewpoint of Serra do Mar, Pleistocene terrace of Itapanhaú river, Paleoterrace of Guazatuba river, River capture of Guazatuba river and Marine terraces of Itaguaré beach. The geodiversity sites are: Granites of Indaiá beach, Gneiss of São Lourenço beach, Rolled stone blocks of Itatinga river and Granites of Cachoeira do Guazatuba. The analysis of the geodiversity ex situ was made in order to identify the types of stones used in the construction of the fortifications, infer the probable origin of these materials, evaluate their conservation status, recognize their current use and present a historical literature review on the remaining fortifications. Based on the results for the geodiversity situ, it was found that the sites with higher possibility of degradation by anthropic activities are those located on beaches and waterfalls due to the large number of visitors, while the sites with low risk of degradation aze protected within environmental protection areas. For their part, the sites with moderate risk of degradation are located on beaches and on non-protected areas. The results for the geodiversity attest that the stone blocks used in the constructions are granites and gneisses, rocks from the Serra do Mar Terrain and other representatives ofthe local geodiversity. Based on these results, proposals were developed for management, publicity and valorization for the geosites and geodiversity sites, and geotourism routes for the fortifications. These proposals present information for geoconservation strategies for the geodiversity and and aim to contribute to the land-use planning in order to protect the geodiversity for this and future generations.
