Intellectual property management between buyer-supplier in the crowdsourcing context

2017

In this paper we investigate the antecedents of buyers’ decisions related to the management of the IPR generated by the suppliers in crowdsourcing contests. Leveraging on Property Rights Theory and interview data, we examine how contest’ attributes affect two buyers’ decisions about (1) whether to define an IPR arrangement ex-ante or negotiating it ex-post with the winning supplier; (2) the choice between strong or weak ownership levels of the IPR arrangement. To test the developed hypotheses, we build a dataset of 819 contests broadcasted on InnoCentive (from 2010 to 2016). Our findings contribute to both the operations management and the crowdsourcing literatures.

The expected value of the traceability information

2015

Abstract Recent regulations on agri-food traceability prescribe traceability throughout the entire supply chain, in order to ensure consumers’ safety and product quality. This has led producers and retailers to consider the opportunity to improve the firm's reputation and consumer confidence through the implementation of traceability systems designed not only to satisfy the legal requirements, but also to track the quality of the products through the supply chain for optimization purposes. However the actual implementation of such systems depends on the possibility of gathering specific information related to the product quality. Nowadays, innovative and non invasive technologies such as th…

On the Bullwhip Avoidance Phase: The Synchronised Supply Chain

2012

Abstract The aim of this paper is to analyse the operational response of a Synchronised Supply Chain (SSC). To do so, first a new mathematical model of a SSC is presented. An exhaustive Latin Square design of experiments is adopted in order to perform a boundary variation analysis of the main three parameters of the periodic review smoothing ( S ,  R ) order-up-to policy: i.e., lead time, demand smoothing forecasting factor, and proportional controller of the replenishment rule. The model is then evaluated under a variety of performance measures based on internal process benefits and customer benefits. The main results of the analysis are: (I) SSC responds to violent changes in demand by re…

Insights on Partial Information Sharing in Supply Chain dynamics

2015

This paper provides an assessment of partial Information Sharing (IS) in Supply Chain (SC). We study the dynamics of collaborative multi-echelon structure, characterized by an increasing level of information visibility among partners. To do so, we mathematically model six four-echelon serial SCs via difference equations and conduct numerical simulations on the basis of a robust design of experiment. Results shows how (1) as the extent of IS increases, the performance of whole SC improves as well, and (2) the impact of IS depends not on which particular members are involved but on the number of collaborative members.

The effect of inventory record inaccuracy in information exchange supply chains

2015

Abstract The goal of this paper is to quantify the impact of Inventory Record Inaccuracy on the dynamics of collaborative supply chains, both in terms of operational performance (i.e. order and inventory stability), and customer service level. To do so, we model an Information Exchange Supply Chain under shrinkage errors in the inventory item recording activity of their nodes, present the mathematical formulation of such supply chain model, and conduct a numerical simulation assuming different levels of errors. Results clearly show that Inventory Record Inaccuracy strongly compromises supply chain stability, particularly when moving upwards in the supply chain. Important managerial insights…

Energy and environmental assessment of the institutional catering in Lombardy (Italy)

2018

Climate change calls for decisive actions to match sustainable development goals, among which key factors are the reduction of energy consumption and carbon footprint. Agri-food sector is one of the main priority areas contained in the European Sustainable Production and Consumption policies, aiming to create more sustainable consumption and production patterns and pushing for environmental international agreements for climate change mitigation and national laws for the efficient use of resources. Public restoration plays a central role in the food consumption sector, at least in developed countries. In particular, institutional catering is playing a relevant role in outdoor meals provided …

Cooperative Inventory control

2005

In multi-retailer inventory control the possibility of sharing setup costs motivates communication and coordination among the retailers. We solve the problem of finding suboptimal distributed reordering policies that minimize setup, ordering, storage, and shortage costs incurred by the retailers over a finite horizon. Neuro-dynamic programming (NDP) reduces the computational complexity of the solution algorithm from exponential to polynomial on the number of retailers.

Coffee biowaste valorization within circular economy: an evaluation method of spent coffee grounds potentials for mortar production

2021

Abstract Purpose Spent coffee grounds (SCG) are biowastes extensively generated within the coffee supply chain. Nowadays, their disposal represents an increasing environmental concern due to its toxicity and organic nature. With the estimated increase of coffee production and consumption in the upcoming years, there is an imperative need to find a proper reverse option, along with a novel industrial application, which allows for the valorization of this coffee by-product within a circular economy perspective. This study aims at investigating a potential reuse of spent coffee grounds to produce novel construction materials to be used for sustainable buildings. Methods After having illustrate…

Life Cycle Assessment of organic apple supply chain in the North of Italy.

2015

The goal of the study is the assessment of the energy and environmental impacts of 1 ton of organic apples cultivated in the North of Italy, by applying the Life Cycle Assessment methodology. The authors examined the supply chain of apples, by including the supply of raw materials and energy sources, and the farming step. In addition, an assessment of apple distribution to the final users was made. The results show that a relevant share of the total impacts is caused by the transport to the final users, assuming that the product is distributed on local, national and international markets. A detailed analysis of the farming step shows that a significant share in the overall energy and enviro…
