O açaizeiro é uma palmeira nativa da Amazônia, de onde é extraída a polpa com alto valor nutritivo, denominada no estado do Pará (região norte do Brasil) de Açaí. O açaí é um dos produtos de maior importância na economia e na dieta alimentar dos paraenses, em especial das famílias que vivem às margens das várzeas, sendo a principal fonte de renda da maioria dos ribeirinhos da região paraense. A crescente demanda pelo produto, por novos mercados em nível nacional e mundial, implicou em aumento de áreas de plantio e alterações no manejo de açaizais tradicionalmente extrativistas, ocasionando mudanças no contexto social, econômico e ambiental. O presente trabalho da pesquisa apresenta resultados do estudo de caso nas várzeas do município de Abaetetuba, considerado um dos maiores produtores do Estado do Pará. A pesquisa de campo evidenciou as relações da cadeia produtiva do açaí no município e demonstrou diferentes tipos de manejo de produção atualmente utilizados em projetos de assentamento agroextrativista, bem como levantou os custos e renda de produção de unidades selecionadas. A pesquisa apontou que as ações e o manejo do açaí em áreas de várzea precisam deixar de focar no crescimento de produção para buscar investir em intervenções de manejo de baixo impacto evitando as problemáticas advindas do adensamento da espécie e a homogeneização da paisagem, com foco na conservação do ecossistema, pois o contrário não se justifica, sequer pela análise econômica. O sistema creditício deve focar também, na promoção da verticalização da cadeia produtiva.

The conditions of declining gold grade in the ore, increasing depth of excavation, and de-creasing unallocated stock of deposits make it necessary to develop efficient solutions for the mine-to-mill process, which have to be adapted to each specific mining plant and will optimizes production costs. Current research focuses on a case study that demonstrates how indicators of mining losses and dilution influence the variation of costs chain in the production cycle. The article examines the topical issue of determining the effects at the mine-to-mill stages due to changes in losses and dilution. The author’s approach to the formation of a mine-to-mill cost chain is proposed by integrating several cost estimation methods into the general cost estimation methodology. The estimation methodology is a compilation of factor analysis and cost engineering methods that take into account the change in costs due to the variation of losses and dilution. It was proven that with variations in losses and dilution, cost savings arise due to changes in the volume of work on ore averaging, ore transportation, and beneficiation. For the case of the Kuranakh ore field, there are no effects at the mining stage. The use of internal reserves by means of managing ore quality parameters allows reducing the costs per ton of processed rock mass along the entire production chain.

Suiker Unie focuses on a strong market position in Northwest Europe at the lowest possible production costs for sugar. The company tries to achieve this by giving attention to the entire production chain. An important pillar of this mission is sustainability. During the recent years Suiker Unie developed a Masterplan to prepare its factories for the new market situation after 2017. In line with Cosun’s strategy of profitable growth, scaling up production capacity of beet factories was defined as goal of this Masterplan. The ambition of reduction of production costs and sustainability (e.g. carbon-footprint) was translated into the challenging constraint to increase the capacity growth within the given steam supply and the actual odour and noise emissions. Based on a thorough bottleneck study a portfolio of measures for each factory is defined, grouped into debottlenecking, energy saving, optimization and environmental projects.

In the present study, a specific and simple second law based exergoeconomic model with instant access to the production costs is introduced. The model is generalized for a case study of Shiraz solar thermal power plant with parabolic collectors for nominal power supply of 500 kW. Its applications include the evaluation of utility costs such as products or supplies of production plant, the energy costs between process operations of an energy converter such as production of an industry. Also attempt is made to minimize objective function including investment cost of the equipments and cost of exergy destruction for finding optimum operating condition for such plant.

Wafer fabrication is a capital intensive industry. A 12-inch wafer fabrication plant needs a typical investment of US$ 3 billion, and the equipment cost constitutes about two-thirds to three-quarters of the total production costs. Therefore, capacity planning is crucial to the investment and performance of wafer fabrication plants. Several formulae are presented to calculate the required number of machines with sequential, parallel, and batch processing characteristics, respectively. An AutoSched AP simulation model using data from real foundry fabrication plants is used in a case study to evaluate the performance of the proposed formulae. Simulation results indicate that the proposed formulae can quickly and accurately calculate the required number of cluster tools leading to the required monthly output rate.

Multi-agent cooperation can in several cases be used in order to mitigate problems relating to task sharing within physical processes. In this paper we apply agent based solutions to a class of problems defined by their property of being predictable from a macroscopic perspective while being highly stochastic when viewed at a microscopic level. These characteristic properties can be found in several industrial processes and applications, e.g. within the energy market where the production and distribution of electricity follow this pattern. Another defining problem characteristic is that the supply is usually limited as well as consisting of several layers of differentiating production costs. We evaluate and compare the performance of the agent system in three different scenarios, and for each such scenario it is shown to what degree the optimization system is dependent on the level of availability of sensor data.

Since 2004, the 130 winegrowers of the Saumur–Champigny appellation d’origine controlee have been committed to biodiversity. In a sector sometimes resistant to change, and indeed for the first time in France, winegrowers have chosen more ecological weed control methods and concentrated on creating and maintaining plant hedges within zones écologiques reservoirs (ecological conservation areas)(ZER) ( Jarno, 2011 ). The growers’ Syndicate, backed by a powerful regional cooperative, rallied all its members and urged them to commit to the process. Collective awareness has driven the majority of winegrowers to ‘go organic’ and with the ultimate benefit of being awarded an organic label. But going organic is costly in terms of time, labour and finances and inevitably increases production costs. However, despite the less favourable cost equation, their business model is nonetheless effective, and most producers manage to sell their entire product. The aim of this case study is to show how some wine producers, in the quest for quality, have ‘looked outside the box’ for new information (for example: sustainable agriculture, biodiversity, biodynamics), assimilated that information and applied it to their own operation and production for improved commercial results.
