armazenamento. A metodologia adotada é baseada no conceito de Ship to Line (STL) no âmbito do Bosch
Production System (BPS). Os resultados obtidos permitiram evidenciar as vantagens da utilização desta
metodologia com ganhos muito significativos para a logística de abastecimento destes componentes
Simulation approach for an integrated decision support system for demand responsive transport planning and operation
Rural areas are becoming more desert from day to day, leading to complex dispersed and scarce demand patterns for public transport. As a consequence, conventional transport services are becoming less frequent, reducing levels of service (e.g., low occupancy rates, usage of old vehicles). With rigid predefined routes and schedules, they are inappropriate to operate in such environments.
Demand Responsive Transport (DRT) systems have been seen as an interesting alternative solution, providing flexible transport services to meet trip requests. This solution has already been adopted in several countries as a way to increase user’s mobility and mitigate social exclusion. There are however some issues concerning DRT scheme design and evaluation requiring further developments. Namely, there is still a lack of adequate tools to support some of the strategic and tactic level decisions that must be made at the design phase.
In this research, we propose an Integrated Decision Support System (IDSS) and general action methodology that will allow achieving better planning decisions and allowing the evaluation of alternative scheme designs prior to its implementation. The IDSS and methodology are based on an event-driven simulation framework which emulates real-world customers’ behavior and vehicles movements. The paper will concentrate its analysis on this framework. An illustrative numerical experiment is presented and briefly discussed.The authors acknowledge the financial support provided by the European Union through FEDER - "Programa Operacional Factores de Competitividade" (POFC) and by the Portuguese Government through FCT - "Fundação para a Ciência e a Tecnologia".

Tecnologias de preparação de pedidos em armazéns: um modelo conceptual para análise e seleção
São inúmeros os desafios enfrentados pelas empresas na atualidade no que diz respeito à sua competitividade num mercado global e complexo, sendo necessário uma permanente revisão e avaliação dos processos de gestão. Melhorias na eficiência do processo de preparação de pedidos (picking) em armazéns é um objetivo extremamente importante, sendo o processo de custo elevado. O objectivo deste paper é apresentar um estudo que visa criar uma metodologia para suportar a escolha de soluções tecnológicas para a estratégia de picker-to-parts. Foi criado um modelo conceptual capaz de incorporar as várias dimensões do processo de decisão sobre avaliação e seleção das tecnologias de preparação de pedidos com base quer na revisão bibliográfica, quer a partir de contribuições de uma empresa fornecedora de tecnologias de picking. No processo de decisão destaca-se a elevada complexidade, pois envolvem vários níveis de decisão e várias dimensões que passam pelo layout do armazém, a metodologia de preparação de pedidos, o nível de rastreabilidade a atingir, o modelo de codificação dos produtos, entre outros fatores determinantes, tal como o custo da própria solução tecnológica

Definition of a collaborative working model to the logistics area
In today’s global economy, the collaboration has become an essential requirement for effective functioning of society. The emergence of Web 2.0 has been indicated as a set of tools to simplify collaboration. The aim of this project is to create an online enterprise community for all logistics employees of Bosch Car Multimedia division in the Bosch Group, for an internal collaboration of the entire Bosch Group based on an IBM Connections platform: Bosch Connect. An additional concern, collected throughout the project, was to bring employees to join the platform, making it a tool of your daily work. Through interviews and a surveys was possible to take the communication and collaboration needs of the target community and thus carry out its construction, based on Design for Six Sigma methodology. As a final result we created the community "Be One Logistics". Despite the limited time to achieve the results (4 months), it was possible to observe an adherence of 71% of the target population. Despite the relatively low number of users (41.7%), some important contributions were made in terms of content updates, and has been a major update in the wiki application, with 77% of the total generated content. Concerning the accesses, there was a balance between the uses of the various applications.This work was supported by FCT “Fundação para a Ciência e a Tecnologia” under the program: PEst2015-2020.info:eu-repo/semantics/publishedVersio
Quality management and supply chain management integration: a conceptual model
Recent trends in the business world has forced companies to expand their activities into new regions where they can
find qualified manpower, lower production costs, high availability of raw materials giving rise to wider and more
complex supply chains but also bringing in new opportunities to leverage their competitive advantages. These
changes require the implementation of new organizational models with different suppliers and partners responsible
for an important part of the final product and consequently to provide a service of excellence to satisfy customers. In
order to produce value and optimize profitability, it is fundamental to establish successful partnerships with the
supply chain organizations that can be achieved by new models of cooperation, improved communication and
integration among all the supply chain partners. The use of advanced management practices is essential to
accomplish these objectives. In this context, the use of integrated approaches to quality management, logistics and
SCM becomes fundamental. Therefore, it will be important to take advantage of TQM and SCM synergies in order
to improve customer satisfaction, increase employee´s motivation and to promote performance of the organization.
In this paper, a conceptual model is presented which reflects the integration of SCM/QM and their impact in
companies’ performance
Definition of a collaborative working model to the logistics area using design for Six Sigma
Purpose - The purpose of this paper is to create an online enterprise community for all logistics employees of Bosch Car Multimedia division in the Bosch Group, for an internal collaboration of the entire Bosch Group based on an IBM Connections platform: Bosch Connect. An additional concern, collected throughout the project, was to bring employees to join the platform, making it a tool of your daily work. The final objective is to implement and promote a tool to foster internal and external integration of the Bosch logistics community.Design/methodology/approach - A case study is presented to illustrate the use of a Design for Six Sigma (DFSS) methodology to support all the process creation of a collaborative community. There are several variants of the methodology DFSS. For the context of this project, will be used the define, measure, analyze, design and verify (DMADV) methodology, that is appropriated to design services processes and it addresses specifically to the remodeling processes.Findings - The use of DMADV methodology allows establish, systematically, a model which was in accordance with the target population needs.Research limitations/implications - Since this is a case study, it is not possible to generalize the results. Furthermore, this project was developed in a limit time (about four months). Thus, was not possible to obtain a large community.Practical implications - The case study brings some evidence of how a systematic approach to the design of a online enterprise community can support designers to meet user's needs.Social implications - A new approach is proposed to meet an online enterprise community user's needs.Originality/value - To the best of the authors' knowledge, there is no evidence the use of this methodology to support a construction of an online enterprise community.info:eu-repo/semantics/publishedVersio
Implementation of multiple criteria decision analysis approaches in the supplier selection process: a case study
Supplier evaluation and selection is recognized as a multiple criteria problem. Having considerable economic impact and influencing a competitive position of a buyer, supplier selection has been modelled by different multiple criteria decision analysis approaches. This case study focuses on the reported "relevance gap" between theoretical approaches to the supplier selection problem and practice. The research was conducted in a textile group, addressing a typical buying situation of a main raw material. The decision process was structured with weighted score, AHP and goal programming models. Three models elaborated have led to the very similar output, recognized as realistic and consistent by the decision makers. Acquired skills of multiple criteria decision analysis were considered as beneficial for supplier selection decisions.This work has been supported by FCT - Fundação para a Ciência e Tecnologia in the scope of the PEst-UID/CEC/00319/2013.info:eu-repo/semantics/publishedVersio
Multiple case study of the supplier selection decision process
The complex and important problem of the supplier selection has been modelled with the involvement and integration of different multiple criteria decision techniques. Nevertheless, there is little empirical evidence of the relevance of such approaches to the procurement practice. In order to overcome the relevance gap it is imperative to analyze the practical decision process in the procurement function. With this aim an exploratory multiple case study was undertaken, based on semi-structured interviews with senior procurement managers of eight Portuguese enterprises, and triangulation with previous research. The results suggest that supplier selection decisions tend to be based on the non-compensatory decision strategy (conjunctive decision rule) in the pre-selection stage, followed by the price bidding and qualitative analysis in the stage of final choice.This work has been supported by FCT – Fundação para a Ciência e Technologia within the Project Scope: PEst-OE/EEI/UI0319/2014.info:eu-repo/semantics/publishedVersio
A constructive heuristic for the multi-compartment vehicle routing problem: an approach for a fuel distribution company
In this paper, we suggest a Decision Support System (DSS) for route planning. This DSS was developed in a real context in a fuel distribution company. This company distributes three types of fuel through multi-compartment vehicles with limited capacity, and satisfying delivery time windows imposed by the customers. Two approaches for this problem were considered: The first one considers the route planning without replenishments while the second one considers the multi-trip case. The solution method is based on a Clarke and Wright savings algorithm incorporating all the constraints referred to above. Both approaches were tested using real instances. The savings for the company, in terms of the distribution process, were identified in the computational results. The DSS may provide an effective support to a complex decision problem.This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT – Fundação para a
