Nouveautés constitutionnelles, juridiques et de politique générale relatives au Droit de l'Environnement et du Développement Durable dans le Royaume du Maroc
Authors: Zyani Brahim
Published: December 2020

While in the past environmental sustainability has been given a lower priority within the overall development policy of the Kingdom of Morocco, the situation has changed significantly in the last decade. Under the reign of King Mohamed VI and already by the end of his father’s regency (King Hassan II) substantial legal, institutional and political developments took place. On the one hand the change is due to drought, the economic crisis, and the recent transitions in the Arab world (“Arab Spring”). On the other hand, international treaties have influenced developments with the effect that laws are being adjusted to a level comparable to those set up by European legislations. This article traces the changes and provides insights into the current situation. With regard to recent constitutional evolutions and their impacts, the rights of citizens to a healthy environment was recognised and institutionalised in an executive authority. Notably, due to a charter environmental matters are now available to a public debate giving public authorities, civil society organisation, the private sector and citizens a right to engage. Currently, the charter awaits its transposition into laws which will be carried out in the coming years. The high significance of international cooperation in environmental – as well as other – matters is acknowledged in the preamble of the Moroccan constitution, with the effect that international treaties, for example the Kyoto Protocol, the Stockholm POP Convention and the Cartagena Protocol, were negotiated and ratified in the national context during recent years. There have also been significant legal developments nationally. While 10 years ago there were hardly any laws addressing the environment in Morocco, today a large number of sectoral regulations acknowledge the value of the different environmental media, defining environmental quality targets as well as addressing authorisation procedures which foresee environmental impact assessment. Further developments involve, for example, the implementation of public participation and access to environmental information, which have already been introduced in some sectoral laws, but will gradually be subject to other sectors, too. These legal developments were followed by institutional changes that generally strengthen the actions of the Moroccan Environmental Department, which itself operates dynamically to fulfil its duties. Nevertheless, the role of local departments needs to be improved since they are still weak in terms of enforcement of the laws.
This article concludes with a critical evaluation of the developments by criticising the absence of a strategic evaluation of the environmental situation and the shortcomings in the field of citizens’ rights and enforcement possibilities due to a lack of personnel and financial resources. Moreover, the lack of coordination between the sectors and unintended effects are addressed.
La protection de l’environnement tunisien au lendemain de la révolution
Authors: Zaier Nejiba
Published: December 2020

This article discusses environmental law in Tunisia with a special focus on the recent developments relating to the abolition of Tunisian dictatorship in January 2011. In addition to discussion of recent activities which followed the revolution, the author provides a brief overview of the sectoral laws on air, water, waste, as well as cultural goods and archaeological and historical heritage, and traditional arts, stating regulatory aims, legal sanction tools and shortcomings under the former regime. Since the dissolution of Tunisian dictatorship, a considerable number of lawsuits have been brought before the courts, in particular concerning restitution of private property. Alongside this, other activities have been undertaken to improve the environmental situation and remedy the damages brought about under the dictatorial regime. The reported means cover working groups seeking ways to sensitise the population by making relevant information available, as well as, more pointed projects involving eco-tourism, consolidation of evaluative and communicative instruments available in environmental governance, etc. In this context, the author specifically points out the role of international cooperation with the EU and actors belonging to the European area. The article also includes a brief reflection on the strengthening of citizens’ rights to a healthy environment while discussions are cur- rently taking place to implement such a right in the constitution.
Hong Kong Convention and EU Ship Recycling Regulation: Can they change bad industrial practices soon?
Authors: Ormond Thomas
Published: December 2020

In May 2009, 63 countries adopted the Hong Kong International Convention for the Safe and Environmentally Sound Recycling of Ships. The agreement was meant to end the anarchy of highly dangerous and extremely polluting ship dismantling practices which are still prevalent on the scrapyard beaches of Southern Asia. However, none of the conference participants has so far ratified the Convention and its entering into force looks far off. In March 2012, the European Commission thus presented a proposal for an EU Ship Recycling Regulation in order to speed up the ratification process as well as to introduce additional measures for European ships. The following article looks at the two legal instruments and their chances of success.
Downsizing our Water Footprint
Authors: Robesin Marga
Published: December 2020

884 million people are without adequate access to clean drinking water and 2.6 billion people lack access to basic sanitary services. Due to preventable water and sanitation-related diseases an average of 5.000 children dies each day. This is not only caused by the absence of local adequate water infrastructure, but also by regional water scarcity. In the near future the problem of water scarcity will even increase in several regions of the world because of factors like a growing world population and climate change. How can we stop this fatal trend? Left aside the need for a better water infrastructure and other measures to improve access to clean drinking water and sanitary services, the global water demand needs to be reduced. Not only for the sake of people, but also for the protection of ecosystems and biodiversity. Using water saving showerheads in our households is not enough to achieve substantial water use reduction. In the past decade scientists have developed methods to calculate our water footprint in the world. In 2011 the Global Standard for Water Footprint Assessment, developed by the Water Footprint Network (WFN) was published. It shows that the major part of our water footprint (WF) consists of water that is used for the production of our food and other products we consume. Famous examples are the 15.000 litres water needed to produce one kg beef or the fact that 140 litres water are used for the production of one (Dutch) cup of coffee. Reduction of humanity's water footprint is urgently needed in order to keep water use within the boundaries of our planet. This article intends to give a short overview of current discussions on the question how to achieve substantial water footprint reduction, focussing in particular on certification and labelling.

Published: December 2020

Lung lobe torsion is one of the causes of dyspnea and respiratory changes in dogs. Twisting of the bronchovascular hilum on its axis, leads to loss of function and metabolic and physiological changes that result in necrosis of the affected lobe. Atelectasis, venous congestion, and pleural effusion secondary to the lobe torsion are responsible for the clinical signs. Chest radiographs or CT scan are used to confirm the diagnosis. In rare cases confirmation is done by exploratory thoracotomy. The prognosis is good after removal of the affected lung lobe. We report a case of left cranial lung lobe torsion in a 17-year-old bitch, successfully treated by lung lobectomy.

Implikasi Kebijakan Ekonomi Umar Ibn Khattab Terhadap Kebijakan Ekonomi Masa Kini
Authors: Hadi Sholikul
Published: December 2020

In the 1970s and 1980s, scientific studies on Islamic economics and finance in the Middle East and other Muslim countries were initiated, which resulted in the establishment of the Islamic Development Bank and banks and other institutions labeled Islam. In fact, the scope of Islamic economics is much broader than just Islamic finance. The author agrees with Taqyuddin An-Nabhani, that generations of Muslims have been fascinated with Capitalist thinking, because they see its success, without fully understanding the reality of its thoughts, even to the inferior feeling (inferiority) of Islam's ability to produce solutions. The purpose of this research is to examine Umar ibn Khattab's policies in distributing Baitul Maal property and to find out the implications of Umar ibn Khattab's policies on today's economy. This research is a literature research (Library Research) with a historical approach, and collects data from primary materials, namely books concerning Umar ibn Khattab's policies and secondary data, namely relevant supporting books. The stages of this research are the analysis of text or phenomena into its components, grouping the same statements and actions into one component, identifying rules that unite various categories, identifying universal rules that construct statements and inter-relations of actions, and systematics of rules obtained through text procedures. or action. The results of this study, namely that during his caliphate, Umar ibn Khattab had made the necessary regulations and took every possible step to ensure that no one was left to starve, without clothing or a place to live in an Islamic country, including the disabled, helpless. because of illness, old age, widows, unemployment, poor people, people who need assistance regardless of caste, skin color, or beliefs are given financial assistance from Baitul Maal. Umar ibn Khattab's policies can be implied in today's economy, such as the prohibition of selling other people's property without the knowledge of the owner, government intervention in the market, prohibition of hoarding assets, reviving dead land, land ownership limits, on found goods, property that is lawful for the government, and criteria for people who have the right to be prioritized for holding and holding government mandates.

Multi-Period Mixed Integer Programming Model for Supply Chain Planning Under Safety Stock
Authors: AKTAS Ahmet , TEMİZ İzzettin
Published: December 2020

Supply chain management philosophy has been adopted by enterprises due to the requirement of customer demand satisfaction in reasonable times under market competition. In case of rapid increase in product demands and/or occurrence of supply problems in materials, enterprises choose holding some amount of safety stock of several materials and products. In this study, a multi-period, multi-product supply chain with different suppliers, material storages, production plants, distribution centers and customers is modeled. To determine the optimal production, supply and storage plans at minimum cost, a mixed-integer programming model is proposed. Capacity, bill-of-materials structure of products and placement of safety stocks are taken into account within the proposed model. Solutions of a set of examples are also presented in order to test the model.

CULTURAL AND CREATIVE ENTREPRENEURS IN FINANCIAL CRISES: SAILING AGAINST THE TIDE?
Authors: Fontainha Elsa , Lazzaro Elisabetta
Published: December 2020

We focus on a number of idiosyncrasies of cultural and creative entrepreneurs (CCEs) to study CCEs’ capacity of resilience under times of downturn (economic, financial and debt crisis). We analyse CC firms’ demography (born and dead), trends and performance and the association between subsidies received and firm survival. We look at mostly micro firms in a country where CCEs are particularly challenged from the financial perspective, namely Portugal. We exploit the unique availability of accounting micro data at private firm level in a time span of 8 years (2004-2011), which allows to include the effects of the latest financial crisis, and to understand the evolution of the economic success criterion. The obtained results about the impact of subsidies on survival are interesting in both CCEs and policy perspectives, suggesting a positive impact of subsidies in periods of downturn, and negative impact of subsidies in periods of growth of the economy. Further, CC firms revealed to be more dynamic than other firms in other sectors.
PORTUGAL IN THE EUROZONE: EVOLUTION AND EXPECTATIONS
Authors: Bação Pedro , Cerdeira Sara , Duarte António Portugal
Published: December 2020

At the time of joining the European Economic Community (precursor to the European Union) and the Eurozone, Portuguese agents were very optimistic about the level of development that the country would be able to achieve as a result of being a member of those economic areas. In this paper we describe the changes occurred in the Portuguese economy since joining the European Union and later the Eurozone. In addition, we provide estimates of the evolution of the expectations of Portuguese agents with respect to long-term real per capita GDP, based on a simple intertemporal macroeconomic model. Over the period under analysis, there was an impressive progress in standards of living. Before joining the euro, Portuguese agents were optimistic about long-term income. Expectations remained high until the onset of the debt crisis, at which time expectations collapsed. A slow recovery is visible in our estimates for the most recent years.
PRICE CLUSTERING IN BANK STOCKS DURING THE GLOBAL FINANCIAL CRISIS
Authors: Lobão Júlio , Pacheco Luís
Published: December 2020

Market anomalies are one of the most intriguing and fascinating phenomena observed in financial markets. This paper examines the incidence of price clustering in US and European bank stocks during the Global Financial Crisis. The results reveal a significant level of price clustering in European and US banks’ samples, which is difficult to reconcile with the Efficient Market hypothesis. The Attraction hypothesis and the Price Resolution/Negotiation hypothesis seem to be the best explanations for the clustering effect. However, the results also suggest that the uncertainty associated with the crisis did not have a significant impact in the clustering levels, which is at odds with the recently proposed Panic Trading hypothesis. Surprisingly, we observe a tendency to have less price clustering during the period of crisis and banks located in countries mostly affected by the European sovereign debt crisis exhibit lower levels of price clustering. These results are consistent with the idea that investors tend to be more analytical in their appraisals in periods of negative sentiment.
Citrus Canker: Developments down the lane
Authors: NASREEN RUKSHANA
Published: December 2020

Citrus canker (caused by Xanthomonas citri ssp.citri , a gram negative bacterium) is considered one of the most feared bacterial diseases of limes/lemons, though affects all types of citrus species. However, there is hardly any citrus species immune to citrus canker in field having severe incidence. Number of field screenings against citrus canker showed Calamondin and Kumquats are highly resistant against citrus canker, while mandarins like Ponkan, Satsuma, Tankan, Cleopatra, Sunki, Sun Chu Sha etc are, though, reported resistant to citrus canker, but their performance under severe incidence of canker still remains a question mark. Chronologically not much developments have taken place , except the physical eradication though pruning and spray of antibiotics and copper- based fungicide still hold the anticipated promise. But of late, biological control of canker using microbial antagonists alongwith obligate entophytes have shown better results under field conditions. These developmental efforts opened up the renewed role of entophytes and novel bioagents to be attempted in a big way against citrus canker. All these issues have been briefly highlighted in this review.

An investigation was carried out to study the performance of various media and nutrients for spider plant (Chlorophytum comosum) in modular vertical walls under vertical green walls in the Department of Horticulture, Annamalai University, Annamalai Nagar (Tamil Nadu) during 2018 to 2020. The experiment comprised of four media viz., coco peat, greenosil, perlite and vermiculite and their combinations and two nutrients viz., foliar nutrition (Grosure NPK 19:19:19 and @ 1% twice (30 and 90 days after planting)) and fertilizer stick (Greenstix sticks were inserted to the modular containers @ one per container at 30 and 90 days after planting). Results revealed that, among the media, plants grown under vermiculite showed better performance in exhibiting maximum values for plant height (24.9 cm), number of leaves (21.6), leaf length (23.8 cm), leaf width (2.43), leaf area (30.9 cm2), shoot weight (15.1 g plant-1), root weight (3.4 g plant-1), biomass (18.4 g plant-1), size index (24.7 cm), and visual quality (9.08). However, among the nutrients, plants inserted with fertilizer stick recorded highest values for plant height (20.9 cm), number of leaves (18.8), leaf length (20.9 cm), leaf width (2.21), leaf area (30.2 cm2), shoot weight (14.8 g plant-1), root weight (3.24 g plant-1), biomass (18.1 g plant-1), size index (22.5 cm), and visual quality (8.49). compared with foliar nutrition. The interaction between media and nutrients was significant and plants grown under vermiculite and containers inserted with fertilizer stick showed superior performance in exerting maximum values for all the characters than other treatment combinations.
Focalisation in Travel Literature "A Study on Three Selected Models"
Authors: AABDULRAHEM Sinan Abdulazeez
Published: December 2020

Focalisation is one of the main concepts in narration; it is basically linked with the narrator in terms of the mechanisms that he follows in presenting views, their angle and the degree of interest in presenting one part to another. As for the narrator, he has full freedom and unique energy to talk about whatever and however he wants. He may have interests in shedding light on political, religious, social, intellectual, philosophical and psychological matters. He may also make the reader compelled to take his comments and points of view, as the narrator is meant to be the window through which readers overlook all events. Thus, the narrator adds his touches to the events in the narration doing things like commenting on events, deleting others to make things ambiguous or adding more details to make the events more interesting. Therefore, narration is always shaped and affected by the role of the narrator, specifically when he is a lonely well-educated and cultured person. The current research studies Focalisation in a specific literary genre, which is the travel literature. It selects three examples from three books authored by: Hassan Abd Radhi, Ahmed Zaki and Anes Mansour respectively and investigates the diversity of those authors' methods of Focalisation. Keywords: Author, Reader, Literature.

Authors: M. D. Pradeep
Published: December 2020

Unorganised sector occupies a predominant portion in the workforce of India. The work is considered to be the physical and mental engagement by human beings for economic
productivity. Fisheries Sector has become a source ofincome and employment to those who engage in unorganised employments for their life. India is the second largest producer of fish in the world by contributing 5.68 per cent of global fish production and second largest producer of fish by aquaculture after China. In the National Fish Productivity, State of Karnataka contributes almost 5.8 per cent securing 6th Position in marine productivity and 9th position in the inland fish productivity. Fisheries sector has enriched its share in the national development after effective usage of technology to increase yield per area of water thereby earning more foreign exchange. Fishing occupation is normally hazardous causing harm to the health of the fisher folks. It is
essential to provide Social security protections to the fisher folks against contingencies including disability, sickness, employment injuries, occupational diseases and unemployment. The maximum welfare to the fisher folks can be assured only through the execution of Comprehensive Social Security Policy linking Social Assistance Programmes and Social Security Schemes. This study is descriptive and analytical in nature. The study results analyse the implications of social security measures among the fisher folks living in the ThotaBengre fishing village of Mangaluru Taluk in Dakshina Kannada District of Karnataka State in India. The study review upon the implications of various social security schemes offered to the fishermen in terms of its coverage and benefit. A good attempt is also made to identify the level of awareness among the fisher folks about social security schemes provided by the government at Centre and State levels respectively. This paper suggests measures for the legislators and fisheries department to improve the benefit schemes thereby securing the inclusive growth of the fishing community.

Biped Walking Control Based on Quadratic Programming and Differential Inequalities
Authors: Diniz Urban Stella , Vilhena Adorno Bruno
Published: December 2020

This paper presents a novel method to control a bipedal walking based on quadratic programming and differential inequalities using geometric primitives. We allow the center of mass to move anywhere inside the support polygon during the walking cycle, as opposed to classic methods, which usually rely on tracking a desired trajectory for the zero moment point. The constraints keep the robot balance, the pelvis above a minimum height, and prevent the violation of joint limits during the complete walking cycle. Simulation results using the legs of the Poppy humanoid robot show that the trajectories of the closed-loop system converge to the desired center of mass position during the double support phase and the swing foot's trajectories converge to the desired pose during the single support phase while all constraints are obeyed.

Authors: Schons Silvane , Coutinho Daniel , Kinnaert Michel
Published: December 2020

This paper deals with the design of a robust lter aimed for fault detection and isolation applied to discrete-time systems subject to arbitrary (not necessarily vanishing) normbounded (i.e., `1) input disturbances. The idea is to approximate the behavior from faults to residual given by a reference model despite the presence of disturbances. The lter design iscast as an optimization problem subject to linear matrix inequality constraints. A numerical example is presented to demonstrate the potential of the proposed approach.

The main contribution of this paper is to present a proposal for the development of an active power filter (APF) for a wind power generation system connected to the electric grid, using the three-phase induction generator with squirrel cage rotor (SCIG). In the induction generator side converter (IGSC) the power control is done by the magnetizing current and electromagnetic torque in coordinates dq. Thus, the wind system controls the active and reactive powers, as well as performing the active filtering function in the grid currents. Harmonic compensation is performed by an algorithm applied to the grid side converter (GSC). That technique improves the power quality and keeps the voltage at DC bus. The studied system was mathematically modeled and simulated using the Matlab / Simulink software. When SCIG provides 2 kW of active power, the THD from 18,94% (without APF) was reduced to 3,93% for GSC operating with APF function.

Os LEDs têm se mostrado cada vez mais presentes nos sistemas de iluminação, desde sistemas de pequeno e médio porte (como residencial e iluminação pública), até mesmo em sistemas maiores (holofotes de estádios, por exemplo). Ao funcionarem em corrente contínua, torna-se necessário a presença de drivers fazendo a interface entre a rede e os mesmos. Esses sistemas de acionamento precisam garantir cada vez mais eficiência, confiabilidade e compatibilidade com normas regulamentadoras. Será apresentado uma série de topologias de drivers trifásicos, acreditando-se que os mesmos são mais interessantes para sistemas de altíssima potência, sobretudo por possibilitarem a remoção do capacitor eletrolítico e consequentemente o aumento da vida útil do sistema como um todo. Duas categorias serão tratadas neste trabalho, a saber: estágio único e modular, as quais possibilitam o estudo de várias topologias já existentes no âmbito de acionamento de LEDs. Serão apresentados os resultados mais relevantes de cada topologia e, por fim, é feita uma comparação minuciosa.

Propõe-se realizar um estudo comparativo entre os métodos de detecção de faltas em linhas de transmissão de corrente contínua multiterminal. Os métodos selecionados para o estudo comparativo pertencem ao grupo dos métodos baseados na teoria de ondas viajantes. Foram utilizados métodos que se baseiam na transformada wavelet discreta, na transformada wavelet discreta redundante, na transformada de park e um método que se baseia na energia da derivada de sinais. O desempenho dos métodos foi analisado com base em simulações realizadas via MATLAB/Simulink de um sistema HVDC (do inglês High Voltage Direct Current) multiterminal. Nas análises para avaliar o desempenho dos métodos, foram variados os pontos de falta, o tipo de falta e a resistência de falta, a fim de testar a robustez dos métodos para faltas de alta e baixa impedância. Em todos os métodos avaliados, foi aplicado um limiar autoadaptativo para detecção de faltas. A partir dos resultados, foi verificado que os métodos que fazem uso da transformada de park e da energia da derivada de sinais obtiveram os melhores desempenhos.

Published: December 2020

Este artigo apresenta uma metodologia para a avaliação do risco de instabilidade em uma microrrede durante a transição para o modo de operação ilhado em um ilhamento não planejado. Nesse caso, a transição bem-sucedida depende da carga e da geração correspondente na microrrede no instante da ocorrência do ilhamento e do esquema de detecção de ilhamento usado para alterar os controles dos geradores. A metodologia é aplicada a uma microrrede composta por geração eólica e geração síncrona. O esquema é aplicado à microrrede considerando um esquema de detecção de ilhamento híbrido, o qual após a detecção da condição ilhada é também responsável por alterar os controles do gerador síncrono distribuído para manter a tensão e a frequência da microrrede nos níveis requeridos. A aplicação da metodologia permite obter o nível de risco de instabilidade na microrrede após a ocorrência de um ilhamento não planejado, de forma que a transição não ocorra de forma bem sucedida.

Detecção de anomalias consiste na identificação de eventos que não estão em conformidade com um padrão de comportamento esperado. No contexto de segurança em vias públicas, a detecção automática de eventos anômalos através de video, tem aplicação na identificação de comportamentos suspeitos. Nesse artigo é proposta uma abordagem para o problema da detecção automática de eventos anômalos em vı́deos de vias públicas baseado em um modelo de redes neurais profundas end-to-end, composto de duas partes: um extrator de caracterı́sticas espaciais baseado em uma rede neural convolucional pre-treinada, e um classificador de sequências temporais baseado em camadas recorrentes empilhadas. Realizamos experimentos nos conjuntos de dados UCSD Anomaly Detection Dataset. Os resultados foram avaliados com as métricas Area Under the Receiver Operating Characteristic Curve - AUC, Area Under the Precision vs Recall Curve - AUPRC e Equal Error Rate – EER. Durante os experimentos, o modelo obteve AUC acima de 95% e EER abaixo de 9%, os quais são resultados compatı́veis com a literatura atual.
Microgrid System Design Based On Model Based Systems Engineering And Goal-Oriented Requirements Engineering

Published: December 2020

Microgrids appear as a practical, clean and reliable solution to meet the demand of populations that, for various reasons, do not have access to electricity. The complexity of microgrid systems, requires considerable engineering eort in the design process. To design this type of complex systems, new approaches, methods, concepts and engineering tools are needed. Where, the requirements analysis has a preponderant role to better characterize, understand and specify the application domain and the problem that the microgrids must solve. This work proposes the introduction of a formal analysis of requirements in the life cycle of microgrid systems, using IEC 61850 as a reference architecture. The requirements would be represented in an Object Oriented Requirements Engineering (GORE) approach, using specically visual diagrams based on the KAOS (Keep All Objectives Satised) method, where the operation and control of the network will be formally represented. The requirements analysis is presented using a combined representation that uses the GORE and Petri Nets methodology for dynamic modeling and formal verication. A case study for small communities in the Amazon rainforest is used as a case study for the proposed method.

Global growth of distributed generation, especially photovoltaic, has given rise to new markets and new problems: large injection of power at daily intervals without increasing in the level of consumption. This scenario has already created, in certain places, overvoltage problems, harmonic distortion, etc. In Brazil, the standards regulate the connection of photovoltaic inverters, however, the control is not yet subject to standardization. For this reason, this paper presents a proposal of local and central algorithms for this power injection control in accordance with the solutions of problems such as the lack of standardization in the communication protocol of the inverters. The results of the pilot plant application are also presented.

Published: December 2020

A busca por um sistema que seja capaz de atender a demanda com segurança e confiabilidade requer o desenvolvimento de ferramentas computacionais que modelem tais equipamentos na prática. Desta forma, realizar um controle de tensão eficaz é cada vez mais essencial para que haja um bom planejamento e operação do sistema. Este artigo realiza uma implementação do controle secundário de tensão no fluxo de potência tradicional em microrredes, considerando unidades de geração distribuída com inversores em droop. A contribuição deste trabalho está baseada na modificação/expansão da matriz jacobiana do fluxo de potência, por meio da inserção do fator de participação dos geradores integrantes de tal controle. A metodologia será aplicada no sistema teste de 38 barras do IEEE e validada por meio do software ANAREDE.

Published: December 2020

O planejamento de tarefas é uma importante área de estudo pois está diretamente ligada ao aumento de produtividade em sistemas industriais, por meio de métricas como makespan e throughput. Esse artigo tem por objetivo apresentar um método de criação de política de seleção de eventos que maximize o paralelismo acumulado em processos modelados por autômatos. Essa política busca produzir sequências de makespan reduzido, para o caso de sequências finitas de eventos, ou de alto throughput, para o caso de produção contínua. Nessa abordagem modelamos o problema como um Processo de Decisão Markoviano, propondo uma modicação no Algoritmo de Iteração de Valor.
