Identifying the optimal strategy for suppliers’ involvement in product design: A case study

In order to increase efficiency and improve competitiveness, manufacturers around the globe are focusing on developing their core businesses. On the other hand, standard activities of engineering are optimally accomplished outside the borders of the firm; thus outsourcing of non-core businesses has become lately a common practice. Product design is considered as one of the most important phases in a product’s life cycle, since the majority of most critical decisions in terms of products’ overall performance are considered during the Research & Development (R&D) phase. Involving suppliers in a firm’s R&D offers significant benefits in various directions, such as feasibility, practicability, sustainability, competitiveness and innovativeness. However, selecting the optimal outsourcing strategy is not an easy decision. On the contrary, it is most challenging since it encompasses a number of different and in many cases mutually conflicting criteria. This paper presents a methodological approach for the selection of the optimal outsourcing strategy for a manufacturer’s R&D. The methodology is based on outranking multicriteria methods and more specifically ELECTRE III. The approach is illustrated and validated through a real world case study of a Greek olive oil producer.   Keywords: product design; suppliers; R&D; outsourcing strategy; multicriteria analysis, ELECTRE II

Do agricultural knowledge and innovation systems have the dynamic capabilities to guide the digital transition of short food supply chains?

The digitalization of agriculture generates a new environment for the actors involved in agrifood production. In such a context, Agricultural Knowledge and Innovation Systems (AKISs) face the challenge of reconsidering their operational paradigms, redefining priorities, and designing strategies to achieve new aims. To do so, the actors participating in AKISs should develop and exploit a set of competencies known as dynamic capabilities, including the aptitude to sense the change in the external environment, the capacity to seize the opportunities that this change creates, and an ability to transform and adapt themselves to the new conditions that digitalization generates. In this study, using as examples the AKISs operating in Greece and Italy, we aimed to uncover if and how actors participating in these systems attempt and manage to deploy such capabilities. Based on a qualitative approach and drawing on data from two workshops, we discovered that seizing the opportunities sensed is a challenging task for AKIS actors. Our results also indicate that knowledge is a pivotal resource for AKISs, allowing actors to enhance their transformative capacity. However, to create a "collective" knowledge base, AKISs should ensure a functional connection between stakeholders and strengthen the roles of actors not actively engaged with the system, like public advisory organizations, universities, and technology providers

Agricultural and food business dynamics in the Mediterranean region: Identifying key indicators for sustainable supply chain systems originated by small-scale farming production

Fruit and vegetables play a crucial role in ensuring food and nutrition security, and developing more sustainable value chains in agriculture and the agri-food sector. To support a greater supply of fruit and vegetables, small farmers' production is fundamental and needs to be integrated into stable value chains to maintain market, logistics and quality conditions. This article develops a theoretical framework based on the conditions, strategies and performances of supply chain systems, combined with the elicitation of expert opinion, to identify key variables for the specific analysis of fruit and vegetable supply chains. Empirical data was retrieved from eight supply chains in five Mediterranean countries to identify the most relevant issues related to their conditions, strategies and performances. Three different types of supply chains were included: 1) Short food supply chains, 2) Green public procurement, and 3) Export-oriented supply chains. This research made it possible to identify key indicators for the analysis of fruit and vegetable supply chain system dynamics. The variables identified in this study may contribute to prospective research for the assessment of fruit and vegetable supply chain sustainability and to the development of policies that encourage the adoption of environmentally-friendly and socially-responsible practices, thus contributing to the long-term sustainability of Mediterranean fruit and vegetables supply chains

Logistics Services Sector and Economic Recession in Greece: Challenges and Opportunities

The recent economic recession in Greece has had a detrimental impact on all national business activities, with the logistics industry being one of the most affected sectors primarily due to the significant decrease in market demand for goods and services. In this regard, the aim of this research is to identify key challenges and prospects for the Greek logistics services industry stemming from the recent economic crisis era through a critical literature taxonomy, a semantic analysis of the reviewed articles, and a questionnaire-based survey involving 140 executives from the third-party logistics sector. In principal, the recent economic crisis is reported to have significantly affected logistics service providers, thus further imposing structural reforms in the industry. The reduction in operating profits of transport companies is noticeable with the onset of the economic crisis, specifically in 2016. Nevertheless, logistics executives are optimistic regarding the near future, provided that educated and informed strategic management decisions are made and inventive business practices are embraced

Identification and modeling of key logistics processes in the Agrifood Sector

As logistics become a substantial part of a firm's operations, the corresponding processes increases in importance. Identifying key logistics processes using a structured approach will align their outcomes to deliver the business goals, design appropriate measures and allocate sufficient resources for their improvement. This paper proposes a systematic methodology for the identification, categorization and prioritization of logistics processes, using a binary linear programming model. The identified key logistics processes are modeled by creating a number of UML diagrams and document them by the use of a pre-defined template. These processes include both inbound and supply chain - wide logistics activities and have a critical effect on the operational performance of an agrifood business entity. Companies can focus on these key logistics processes in order to optimize their critical aspects such as time and cost issues, resources planning and scheduling, as well as, queues and delay

Decision support model for evaluating alternative waste electrical and electronic equipment management schemes-A case study

Waste of electrical and electronic equipment (WEEE) is a constantly increasing component of the total volume of municipal solid waste. E-waste streams are expected to continue escalating in the near future. The underlining paradox lies in the fact that end-of-life electrical and electronic equipment constitute a critical waste stream owing to the contained hazardous and toxic elements, but they also present an important source of valuable raw materials. Therefore, identification of alternative scenarios for integrated WEEE management is imperative. To that end, this research develops a methodological approach that focuses on determining the optimal WEEE management scheme, among available alternatives, applicable to the specific case of Greece. In particular, a binary linear programming model is formulated that maximizes the performance of 9 alternative WEEE management scenarios. The mathematical model considers 12 performance assessment criteria identified across financial, technical, social, and environmental dimensions. Priority levels are assigned to each criterion based on the input of 19 involved experts. A range of "what-if" analyses indicate that mechanical recycling of WEEE, in tandem with exporting of residues, is the most efficient e-waste management strategy in the case of Greece. The research findings indicate that the joint cooperation of all stakeholders, together with political will and effectiveness, is required for the integrated WEEE management at a national level
