Economic evaluation of PDO introduction in Sicilian orange farms

2014

The south-western part of Sicily is the largest Italian production area of Navel oranges where in 2008 it was established the Arancia di Ribera Prot ected Designation of Origin (PDO). The aim of the paper was to ana lyze the effect that the PDO introduction determined on farm profitability and sustainability. To this end, it was carried out an economic analysis on some representative orange farms of PDO area.

Socio-economic assessment of direct sales in Sicilian farms

2015

Many farmers today adopt direct sales as an entrepreneurial strategy in order to achieve a competitive advantage. The aim of this study has been to analyze the role that direct sales play in Sicilian farms and how the short food supply chain is able to valorize the endogenous resources of rural areas and increase the net income of farmer. Our results showed that direct sales, in conjunction with conventional sales, can represent a growing opportunity for farmers and lead to an improvement in the economic performances of agricultural businesses, an increase in farm investments and the creation of new job opportunities.

Evolution of qualitative characteristics during blueberry fruit storage in a modified atmosphere

2015

The objective of this work was to evaluate the performance of different films to maintain MAP conditions for storing ‘Duke’ blueberries by verifying the evolution of qualitative traits of berries. The fruits were picked manually, individually deposited in polyethylene baskets and immediately transferred (1 h) to the laboratory under chilled conditions (10°C). The experimental storage units consisted of a pallet bag of two different types of film, polyethylene (100 μm) and a biobased film derived from starch (50 μm). The O2 and CO2 transmission rates, measured according to the ASTM F 2622-08 and ASTM F 2476-05 methods at 38°C and 90% RH, were, 2642 and 10654 [cm3/(m2·24 h)], respectively, fo…

Modeling Alternatives Sustainable-Energy-Policy for the Supply Chain of Wind Power in Brazil.

2020

Renewable energy studies have received high attention in the last few years due the increasing deployment of alternatives such as wind, solar and biomass, as a result of the urgency in reducing fossil fuels consumption. This situation has involved an important challenge for long-term renewables policy and energy system planning. Brazil is the richest country in terms of renewable sources in Latin American. Brazil has energy generation portfolio not much different form the Colombia one, and the understanding of this very important country will contribute to inspire other countries in the region, particularly Colombia. Since 2004 the Brazilian energy policy promotes wind power development aim…

The Impact Of Demand And Inventory Management Policies On Bullwhip Effect In Production Networks

2004

The bullwhip effect is a phenomenon consisting in variance amplification of orders as they move up a supply chain. The immediate bullwhip effect consequences are the increase of inventory costs, poor custoiner services and inefficient utilization of resources due to the difficulties of production planning activities in highly variable conditions. There are many factors that cause the bullwhip effect, but if is particularly due to demand forecasting and inventory management policies. In this paper the impact on bullwhip effect of different policies to manage demand and inventories has been evaluated through discrete event simulation, using the ARENA (R) simulation package.

Using simulation to analize wind power penetration: the case of North and Northeast Region

2017

Brazil is rich in renewable sources that can be used for energy generation. The renewable source of energy generation predominantly in Brazil is hydropower. However, the availability of hydropower depends on the useful volume reserves, which is subject to rainfall. Consequently, wind power is a renewable source that is being integrated into the electricity-interconnected system in Brazil. The growth of wind power generation depends on the financial resources and the delays in transmission projects. Despite the Brazilian incentives policy in wind power, the insufficient of transmission infrastructure affects to electricity price in electricity market. This paper addresses the effects of the …

Information Sharing and Channel Construction of Supply Chain under Asymmetric Demand Information

2014

Information sharing and marketing channel building have become an important problem of supply chain management theory and practice. The research of information sharing focused on traditional channel of supply chain between upstream and downstream enterprises; however, the research ignores the behavior of information sharing with potential entrants and composite structure characteristics about traditional marketing channel with the direct channel. This paper uses the model to research the effects brought about sharing demand information with potential entrants and building marketing channel, which reveals information sharing and channel building mechanism in the supply chain. The study found…
