Environmental Risk Management and the Business Firm

This chapter considers three matters that business firms whose activities can be dangerous for human health and the environment increasingly have to deal with: public disclosure of all health and environmental risks, direct involvement of stakeholders in the management of operations, and integration of health and environmental risk management with the management of other business risks. It summarizes recent managerial economics research on those matters and suggests some promising research areas. Ce chapitre considère trois questions qui préoccupent de plus en plus les firmes dont les activités font peser certains risques sur la santé humaine et l'environnement, soit la révélation au public de ces risques, l'implication directe de parties externes (assureurs, banquiers, représentants du public, etc.) dans la gestion des opérations, voire la planification stratégique, et la gestion intégrée de tous les risques d'affaires. On résume les récentes percées de l'économie managériale sur ces sujets, et l'on indique certaines pistes de recherche particulièrement prometteuses.Environmental risk disclosures, extended liability, integrated risk management, Bilan environnemental, responsabilité étendue, gestion intégrée des risques

ANALYTICAL ASSESSMENT OF ENERGY EFFICIENCY POLICIES: A CASE STUDY OF NORWEGIAN POLICY MAKING

This study provides a throughout review of Energy Efficiency policies in the Norwegian context. It examines specific policies and instruments which are designed for addressing Energy Efficiency issues. The aim is to grasp the extent and effectiveness of those policy arrangements that might serve as a model for others to learn from. Qualitative and quantitative data collected from evaluation reports and databases show a tendency of overall improvement of Energy Efficiency trends over the last four decades with inconsiderable fluctuations, which are an outcome of external economic factors and less accountable to policy making. Findings also reveal the complex nature of policy assessment and, indicate the need for further detailed research on Energy Efficiency policies in different contexts if recommendations from well performers are to be realized. Further research will also allow for a better evaluation of Energy Efficiency policy impacts and deepen knowledge in overall policy evaluation methods

Simulation and optimization model for the construction of electrical substations

One of the most complex construction projects is electrical substations. An electrical substation is an auxiliary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using transformers. Construction of electrical substation includes civil works and electromechanical works. The scope of civil works includes construction of several buildings/components divided into parallel and overlapped working phases that require variety of resources and are generally quite costly and consume a considerable amount of time. Therefore, construction of substations faces complicated time-cost-resource optimization problems. On another hand, the construction industry is turning out to be progressively competitive throughout the years, whereby the need to persistently discover approaches to enhance construction performance. To address the previously stated afflictions, this dissertation makes the underlying strides and introduces a simulation and optimization model for the execution processes of civil works for an electrical substation based on database excel file for input data entry. The input data include bill of quantities, maximum available resources, production rates, unit cost of resources and indirect cost. The model is built on Anylogic software using discrete event simulation method. The model is divided into three zones working in parallel to each other. Each zone includes a group of buildings related to the same construction area. Each zone-model describes the execution process schedule for each building in the zone, the time consumed, percentage of utilization of equipment and manpower crews, amount of materials consumed and total direct and indirect cost. The model is then optimized to mainly minimize the project duration using parameter variation experiment and genetic algorithm java code implemented using Anylogic platform. The model used allocated resource parameters as decision variables and available resources as constraints. The model is verified on real case studies in Egypt and sensitivity analysis studies are incorporated. The model is also validated using a real case study and proves its efficiency by attaining a reduction in model time units between simulation and optimization experiments of 10.25% and reduction in total cost of 4.7%. Also, by comparing the optimization results by the actual data of the case study, the model attains a reduction in time and cost by 13.6% and 6.3% respectively. An analysis to determine the effect of each resource on reduction in cost is also presented

Working Capital Management and Profitability: An empirical Investigation in an Emerging Market.

The paper seeks  to examine the effect of working capital management (WCM)  on firms’ performance for non-listed Ghanaian firms. The paper includes conceptual as well as empirical analysis in which data from a sample of non-listed firms from 2004-2009 are analyzed to examine if efficient WCM improves firms’ profitability. Cash conversion cycles as well as its components are used as measures of WCM skills. Gross operating Profit to Total Assets is used as performance measure. This paper found that, profitability is negatively related to the length of the cash conversion cycle. The results demonstrate that managers can create value by reducing their firm’s number of day’s accounts receivable and inventories. Also, performance is affected positively by the firms’ size, GDP growth and firms’ sales growth. This work’s originality and value lies in suggesting that policy makers in emerging markets need to motivate and encourage managers and shareholders to give more attention to working capital management. Keywords: Working Capital Management,  Profitability, Cash Conversion Cycl

Shedding Light on the Blockchain Disintermediation Mystery: A Review and Future Research Agenda

Blockchain technology has been in the interest of IS researchers and practitioners for several years. One key reason for this curiosity is the possibility to carry out peer-to-peer transactions without a trusted intermediary. Building upon this capability, many researchers posited that blockchain technology would remove traditional intermediaries from their market position. This process has been described in electronic markets literature as Disintermediation. However, other researchers proposed a more distinct perspective by proposing that blockchain technology will not facilitate Disintermediation in all settings. Thus, no unified view on this topic exists yet. Our literature review identifies three dominating concepts in blockchain literature: Extensive Disintermediation, Limited Disintermediation, and Re-Intermediation. We further highlight in our findings that most of the identified literature does not consider all market functions as described in the electronic markets literature. Hence, we provide a structured overview of the field and possibilities for future research

Modelling lean and green supply chain

Dissertação para obtenção do Grau de Doutor em Engenharia IndustrialThe success of an organization depends on the effective control of its supply chain. It is important to recognize new opportunities for organization and its supply chain. In the last few years the approach to lean, agile, resilient and green supply chain paradigms has been addressed in the scientific literature. Research in this field shows that the integration of these concepts revealed some contradictions among so many paradigms. This thesis is mainly focused on the lean and green approaches. Thirteen different management frameworks, embodied in awards, standards and tools were studied to understand if they could contribute for the modelling process of a lean and green approach. The study reveals a number of categories that are common in most management frameworks, providing adequate conditions for a lean and green supply chain transformation. A conceptual framework for the evaluation of a lean and green organization`s supply chain was proposed. The framework considers six key criteria, namely, leadership, people, strategic planning, stakeholders, processes and results. It was proposed an assessment method considering a criteria score for each criterion. The purpose is to understand how lean and green supply chain can be compatible, using principles, practices, techniques or tools (i.e. elements) that support both, a lean and a green approach, in all key criteria. A case study in the automotive upstream supply chain was performed to understand more deeply if the elements proposed for the conceptual framework could be implemented in a real-scenario. Based on the conceptual framework and the case study, a roadmap to achieve a lean-green transformation is presented. The proposed roadmap revealed its contribution to the understanding on how and when an organization`s supply chain should apply the lean and green elements. This study is relevant to practice, as it may assist managers in the adoption of a lean and green supply chain approach, giving insights for the implementation of a hybrid supply chain.Fundação para a Ciência e a Tecnologia - (PhD fellowship: SFRH/BD/60969/2009); Project entitled "Lean, agile, resilient and green supply chain management" (LARG_SCM) which facilitated the development of case study and make possible the submission of papers at several International Meetings and Conference

A journey towards Industry 4.0 : the supporting role of socio-technical systems

Companies seek to improve their competitiveness and productivity through innovation in processes, products, and equipment. This innovation can be achieved via technologies that bring greater quality, flexibility, efficiency, control, and monitoring to their production. In this sense, the concept of a more intelligent, automated, and digital industry gained interest and culminated in Industry 4.0. Many companies view this industry evolution as capable of delivering immediate improvements and lowering production costs. However, only crediting the technology with gains in productivity, quality, and flexibility has brought frustrations, complexity, and reduced production in company processes. This is due to, among other things, the way Industry 4.0 technologies are understood, implemented, communicated, and used. Literature and empirical studies have shown that companies still lack the technological, cultural, and process maturity necessaries to obtain substantial gains with Industry 4.0, especially small and medium-sized companies. Focusing on this technology implementation process, this thesis aims to investigate how the socio-technical theory can bring improvements and gains in relation to the environment in which technologies such as IoT, big data, analytics, collaborative robots, and 3D printing are implemented. For that, this thesis aims to identify how the socio-technical aspects impact the implementation of Industry 4.0 and its contribution to improving the results with its implementation. The results demonstrate that socio-technical aspects are associated with higher levels of Industry 4.0 implementation as they serve as the basis for technologies to operate in a more organized environment, with workers trained and engaged in their use and with a clear and delimited strategy. Strategic aspects are the most impacting aspects of Industry 4.0 implementation and should be considered fundamental for companies adopting its technologies. The qualitative results highlight such importance and demonstrate how companies have made such a transition both through Industry 4.0 ecosystems, as well as seeking capabilities and knowledge through suppliers, consultancies, associations, and startups. Still, the results showed the importance of collecting, storing, and having the ability to use data for continuous improvement. Well-established lean maturity and the definition of a strategic and technological roadmap that guides the technology implementation process were also essential for the company to focus on a broader context of technologies to the detriment of ad-hoc implementations. Finally, the results also showed that although aspects of strategic definition bring important gains for implementing Industry 4.0, improvements related to workers, such as engagement, qualification, and training, can also bring productivity improvements. In this way, this thesis brings theoretical and empirical gains to a field of growing interest for the industry that demands high investments, impacting not only workers but various organizational, social, and technical aspects of the company. The results discussed here provide empirical evidence of the importance of a socio-technical vision based on more organized processes, a well-defined strategy, and trained, engaged, and participative workers in the transition to Industry 4.0, in contrast to the technocentric vision generally adopted by companies.Empresas buscam melhorar sua competitividade e produtividade através de inovações em processos, produtos e equipamentos. Tais inovações podem ser feitas através de tecnologias que tragam maior qualidade, flexibilidade, eficiência, controle e monitoramento a sua produção. Nesse sentido, o conceito de uma indústria mais inteligente, automatizada e digital ganhou força e culminou no que se denomina de Indústria 4.0. Muitas empresas visualizam essa evolução da indústria como capaz de entregar melhorias imediatas e diminuir custos de produção. No entanto, creditar somente à tecnologia ganhos de produtividade, qualidade e flexibilidade tem trazido frustrações, diminuição na produção e complexidade aos processos das empresas. Isso se deve, entre outras coisas, à forma como as tecnologias da Indústria 4.0 são entendidas, implementadas, comunicadas e usadas. Estudos empíricos têm demonstrado que as empresas ainda não possuem maturidade tecnológica, cultural e de processos para obter ganhos substanciais com a Indústria 4.0. Com foco nesse processo de implementação de tecnologia, esta tese visa estudar como a abordagem sistêmica e holística proposta pela teoria socio-técnica pode trazer melhorias e ganhos em relação ao ambiente em que as tecnologias como IoT, big data, analytics, robôs colaborativos e impressão 3D são implementadas. Para isso, essa tese tem como objetivo geral identificar como os aspectos socio-técnicos impactam a implementação da Indústria 4.0 e sua contribuição para melhorar os resultados com a sua implementação. Os resultados demonstram que os aspectos socio-técnicos estão associados a níveis mais altos de Indústria 4.0 uma vez que servem de base para que as tecnologias possam operar em um ambiente preparado, com trabalhadores treinados e engajados em seu uso e com uma estratégia clara e delimitada. Os aspectos estratégicos são os que mais impactam no nível de adoção de Indústria 4.0 e são fundamentais para a adoção das tecnologias. Os resultados qualitativos ressaltam tal necessidade e demonstram como as empresas têm feito tal transição tanto através de treinamentos, parcerias com startups e organizações governamentais, assim como buscando capabilidades e conhecimento através de fornecedores, universidades e consultorias. Ainda, os resultados evidenciaram a importância de coletar, armazenaram e possuir capacidade de utilizar dados para melhorias contínuas. Maturidade lean bem estabelecida e a definição de um roadmap estratégico e tecnológico que guie o processo de implementação das tecnologias também foi demonstrado como essencial para que a empresa foque num contexto mais amplo de tecnologias em detrimento de implementações pontuais e usos ad hoc. Finalmente, os resultados também demonstraram que apesar de aspectos de definição estratégica trazerem ganhos importantes para a implementação de Indústria 4.0, melhorias relacionadas a trabalhadores, como engajamento, qualificação e treinamento também são capazes de trazer melhorias na produtividade. Dessa forma, essa tese traz ganhos teóricos para um campo crescente e de interesse da indústria e que demandam investimentos altos, impactando não somente os trabalhadores, mas diversos aspectos organizacionais, sociais e técnicos da empresa. Os resultados discutidos aqui trazem evidências empíricas da importância de uma visão socio-técnica pautada em processos mais organizados, estratégia bem definida e trabalhadores treinados, engajados e participativos na transição para a Indústria 4.0 em contraste a visão tecnocentrista geralmente adotada pelas empresas
