Partner selection for reverse logistics centres in green supply chains: a fuzzy artificial immune optimization approach

The design of reverse logistics networks has now emerged as a major issue for manufacturers, not only in developed countries where legislation and societal pressures are strong, but also in developing countries where the adoption of reverse logistics practices may offer a competitive advantage. This paper presents a new model for partner selection for reverse logistic centres in green supply chains. The model offers three advantages. Firstly, it enables economic, environment, and social factors to be considered simultaneously. Secondly, by integrating fuzzy set theory and artificial immune optimization technology, it enables both quantitative and qualitative criteria to be considered simultaneously throughout the whole decision-making process. Thirdly, it extends the flat criteria structure for partner selection evaluation for reverse logistics centres to the more suitable hierarchy structure. The applicability of the model is demonstrated by means of an empirical application based on data from a Chinese electronic equipment and instruments manufacturing company.

Modelo institucional do processo de estruturação de empresas de desenvolvimento de software: um estudo de múltiplos casos

Some authors have shown the need of understanding the technological structuring process in contemporary firms. From this perspective, the software industry is a very important element because it provides products and services directly to many organizations from many fields. In this case, the Brazilian software industry has some peculiarities that distinguish it from other industries located in developed countries, which makes its understanding even more relevant. There is evidence that local firms take different strategies and structural configurations to enter into a market naturally dominated by large multinational firms. Therefore, this study aims to understand not only the structural configurations assumed by domestic firms but also the dynamic and the process that lead to these different configurations. To do so, this PhD dissertation investigates the institutional environment, its entities and the isomorphic movements, by employing an exploratory, descriptive and explanatory multiple cases study. Eight software development companies from the Recife's information technology Cluster were visited. Also, a form was applied and an interview with one of the main firm s professional was conducted. Although the study is predominantly qualitative, part of the data was analyzed through charts and graphs, providing a companies and environment overview that was very useful to analysis done through the interviews interpretation. As a result, it was realized that companies are structured around hybrids business models from two ideal types of software development companies, which are: software factory and technology-based company. Regarding the development process, it was found that there is a balanced distribution between the traditional and agile development paradigm. Among the traditional methodologies, the Rational Unified Process (RUP) is predominant. The Scrum is the most used methodology among the organizations based on the Agile Manifesto's principles. Regarding the structuring process, each institutional entity acts in such way that generates different isomorphic pressure. Emphasis was given to entities such as customers, research agencies, clusters, market-leading businesses, public universities, incubators, software industry organizations, technology vendors, development tool suppliers and manager s school and background because they relate themselves in a close way with the software firms. About this relationship, a dual and bilateral influence was found. Finally, the structuring level of the organizational field has been also identified as low, which gives a chance to organizational actors of acting independently

A MODEL FOR EVALUATING IMPACT OF BUSINESS PROCESS MANAGEMENT IN ORGANIZATIONAL PERFORMANCE

Business Process Management (BPM) is able to organize and frame a company focusing in the improvement or assurance of performance in order to gain competitive advantage. Although it is believed that BPM improves various aspects of organizational performance, there has been a lack of empirical evidence about this. The present study has the purpose to develop a model to show the impact of business process management in organizational performance. To accomplish that, the theoretical basis required to know the elements that configurate BPM and the measures that can evaluate the BPM success on organizational performance is built through a systematic literature review (SLR). Then, a research model is proposed according to SLR results. Empirical data will be collected from a survey of  larg and mid-sized industrial and service companies headquartered in Brazil. A quantitative analysis will be performed using structural equation modeling (SEM) to show if the direct effects among BPM and organizational performance can be considered statistically significant. At the end will discuss these results and their managerial and cientific implications.Keywords: Business process management (BPM). Organizational performance. Firm performance. Business models.

Contributo da filosofia Lean na redução do custo de uma peça metálica

Num mercado cada vez mais exigente e competitivo, torna-se imprescindível que as organizações otimizem continuamente os seus sistemas produtivos. Muitas têm visto nas filosofias e práticas Lean e Kaizen as respostas para conseguirem produzir mais sem acrescentar recursos, e de forma mais rápida, mais eficaz e mais eficiente. O envolvimento da empresa numa cultura de melhoria contínua orientada para o cliente permite a criação de valor em todas as etapas, tornando-a mais flexível e competitiva. Essa transformação cultural, aliada à aplicação de ferramentas Lean e Kaizen, permitem melhorar o desempenho global da organização, reduzindo os custos através do combate aos inibidores de performance: os desperdícios, os paradigmas, a inflexibilidade e a variabilidade. No presente trabalho pretende-se mostrar a aplicabilidade de algumas destas ferramentas no processo produtivo de um componente metálico para a indústria mobiliária, assim como os ganhos alcançados com esta abordagem. Ao longo de todo o projeto foram usadas diversas ferramentas Lean Manufacturing como organização do posto de trabalho (5S), Gestão Visual, troca rápida de ferramentas (SMED), mapeamento da cadeia de valor (VSM) e alterações de layouts (com recurso ao software Arena e AutoCad para estudar a alteração mais eficiente que permitisse uma maior produtividade com menor quantidade de recursos). Também se mostra igualmente a importância dos colaboradores no processo de mudança, através das iniciativas Kaizen, do programa de sugestões, dos inquéritos de satisfação e das ações de formação, para que eles se sintam parte integrante da organização.

Managerial experiences related to corporate demerger

In the current economic situation very few business operations are static. In some cases, organizations feel that the most rational solution is not expanding but focusing on their core competencies or certain areas of business through corporate restructuring. The focus in this thesis is on corporate demerger, a process that involves a complete separation of units within a company. Despite the vast amount of research considering corporate demergers, there is still a lack of knowledge about how top managers experience these kinds of organizational rearrangements. In this qualitative case study, the aim is to bring forward the thoughts of executives in two companies that emerged from a single company through corporate demerger a few years ago. By conducting dyadic semi-structured interviews with the management group and board members in both the parent company and the demerger company, I pursue to understand the impressions that they had during the demerger process as well as during the change that followed afterwards. Additionally, their retrospective sense-making patterns are briefly examined. The findings suggest that the way operations are managed before plays an important role in the demerger process. In this case the pre-demerger organization was quite distinctly divided into two business areas, which allowed a somewhat natural allocation of resources. In addition, apart from the top management, every employee knew their future company and role, thus decreasing the amount of uncertainty in lower organizational levels. Consequently, the ambiguity and change faced by the top executives was evidently more powerful compared to the operational actors. The fragmented characteristics also enabled certain points of reference in the unfolding demerger process. Along with the information about future management groups, the pre-demerger re-grouping took place. This sparked up the mental division, where both groups started to act separately. On a personal level, the managers involved in the demerger planning have made retrospective sense of the repercussions related to the restructuring process. For them, it was an extremely demanding, ambiguous and burdensome project that provided them with managerial experiences they are likely not to have again.
