Efecto Bullwhip y restricciones de capacidad productiva en las cadenas colaborativas
2008
El objetivo del presente artículo es profundizar en el análisis de Evans y Naim (1) sobre la relación entre la capacidad de limitada producción y el efecto bullwhip, y actualizarlo en función de las recientes configuraciones de cadenas de suministro colaborativas. Se analizan tres cadenas de suministro con capacidad de producción limitada: la misma cadena de suministro tradicional estudiada por Evans y Naim (1), una cadena EPOS (Exchange Point of Sales) y una cadena sincronizada. Se adopta un sistema de métricas para evaluar los beneficios de los nodos de la cadena medidos en términos de estabilidad de la orden de pedido, estabilidad de los inventarios, y robustez del sistema, y en términos…
Modelling the Bullwhip Effect Dampening Practices in a Limited Capacity Production Network
2009
This work infers on the conjoint adoption of collaboration practices and replenishment rules as bullwhip dampening techniques in a limited capacity production network. Continuous time differential equation methodology is adopted to model three supply chain configurations. Results show that theconditio sine qua non for long-term capacity strategy is the management and control of information asynchronies, provided by collaboration practices and ad-hoc decision policies. Furthermore the study reveals the phenomenon of bullwhip rough dampening.
Fair Transfer Prices of Global Supply Chains in the Process Industry
2016
This work addresses the optimisation of transfer prices for the fair profit distribution among the members involved in a global supply chain in the process industry. A mixed integer linear programming (MILP) model is developed for production and distribution planning of global supply chains, where the optimal transfer prices of products between plants and markets are determined. Two solution approaches are presented for fair solutions using Nash and lexicographic maximin principles. The applicability of the proposed models and approaches are demonstrated by an illustrative example. The results show that both approaches can fairly distribute the whole supply chain’s profit to the members.

A multi-agent decision support system for dynamic supply chain organization
2011
In this work, a multi-agent system (MAS) for supply chain dynamic con- figuration is proposed. The brain of each agent is composed of a Bayesian Decision Network (BDN); this choice allows the agent for taking the best decisions esti- mating benefits and potential risks of different strategies, analyzing and managing uncertain information about the collaborating companies. Each agent collects infor- mation about customer’s orders and current market prices, and analyzes previous experiences of collaborations with trading partners. The agent therefore performs a probabilistic inferential reasoning to filter information modeled in its knowledge base in order to achieve the best performance in t…
Negotiation Models in Manufacturing E-Marketplaces
2005
This chapter describes the negotiation model adopted by the Customer and Supplier Negotiation Agents in the agent based architecture described in Chapter 2. The chapter is structured as it follows: in the first section the use of automated negotiation in modern market scenario is motivated; in the second section, starting form the contributions presented in the scientific literature, automated negotiation will be analysed and a taxonomy will be proposed. The third section is dedicated to the e-market context discussed in this book and in particular the impact of negotiation in manufacturing e-marketplaces will be stressed: its impact is strictly related to the electronic nature of e-marketp…
Opening the black box of food quality in the short supply chain: Effects of conventions of quality on consumer choice
2015
In recent years new forms of food distribution organisation, known as short supply chains, have gained ground. The local nature of such distribution has positive effects on the environment and on the local economy. Consumers appear to trust the short supply chain, and it has achieved considerable success. However, the short supply chain has credence characteristics which, by their very nature, cannot be identified through a system of certification. The question we address in this paper is whether it is possible to identify the constituent elements of the credence trait in relation to food quality in the short supply chain. Our hypothesis is that the latter are linked to a range of socially …
Are "good guys" more likely to participate in local agriculture?
2015
Abstract In recent years a new form of food production and distribution organisation, as part of small-scale and local agriculture, has been gaining ground. Generically termed short supply chains (SSCs), this new model of food procurement comprises various forms such as community-supported agriculture, box schemes and solidarity purchase groups. Consumer participation in SSCs is dictated by deep motivations: while consumers are principally encouraged by the desire to preserve local producers, as well as the social and environmental aspects of farming, the attraction of SSCs is also tied to different and more complex ways of perceiving food quality. The quality issue in SSCs is not only seen…
Life Cycle Assessment of organic and conventional apple supply chains in the North of Italy
2017
Abstract This paper compares the energy and environmental impacts of organic and conventional apples cultivated in the North of Italy, by applying the Life Cycle Assessment (LCA) methodology. The authors examined the supply chain of apples, including the input of raw materials and energy sources, the farming step, the post-harvest processes and the distribution of apples to the final users. The paper develops two original contributions: 1) it enhances the limited number of studies on LCA applied to apples; 2) it compares organic and conventional apples produced in lands characterized by the same climatic conditions, to evaluate which of the two products is more competitive from an energy an…
A methodology for developing evidence-based optimization models in humanitarian logistics
2022
AbstractThe growing need for humanitarian assistance has inspired an increasing amount of academic publications in the field of humanitarian logistics. Over the past two decades, the humanitarian logistics literature has developed a powerful toolbox of standardized problem formulations to address problems ranging from distribution to scheduling or locations planning. At the same time, the humanitarian field is quickly evolving, and problem formulations heavily rely on the context, leading to calls for more evidence-based research. While mixed methods research designs provide a promising avenue to embed research in the reality of the field, there is a lack of rigorous mixed methods research …
