  Title A methodology for stochastic inventory models based on a zero-adjusted Birnbaum-Saunders distribution Type Journal Article
  Year 2016 Publication Applied Stochastic Models In Business And Industry Abbreviated Journal Appl. Stoch. Models. Bus. Ind.  
  Volume 32 Issue 1 Pages 74-89  
  Keywords demand data; financial indicators; maximum likelihood method; mixture distributions; Monte Carlo simulation; R software  
  Abstract The Birnbaum-Saunders (BS) distribution is receiving considerable attention. We propose a methodology for inventory logistics that allows demand data with zeros to be modeled by means of a new discrete-continuous mixture distribution, which is constructed by using a probability mass at zero and a continuous component related to the BS distribution. We obtain some properties of the new mixture distribution and conduct a simulation study to evaluate the performance of the estimators of its parameters. The methodology for stochastic inventory models considers also financial indicators. We illustrate the proposed methodology with two real-world demand data sets. It shows its potential, highlighting the convenience of using it by improving the contribution margins of a Chilean food industry. Copyright (c) 2015 John Wiley & Sons, Ltd.

  Title Participatory indicators of sustainability for the salmon industry: The case of Chile Type Journal Article
  Year 2015 Publication Marine Policy Abbreviated Journal Mar. Pol.  
  Volume 51 Issue Pages 322-330  
  Keywords Latin America; Chile; Sustainable development; Indicators; Stakeholder analysis  
  Abstract In this paper a methodological approach is proposed and applied to undertake a participatory process to obtain sustainable development indicators for the salmon sector in Chile including a common vision of sustainability for this industry. The selected indicators are a mix of bottom-up and top-down approaches, which capture the specific needs and perceptions of the different stakeholders related to salmon farming while allowing a high degree of international comparability. A detailed step by step description of the methodology allows understanding how to obtain acceptable social, economic and environmental indicators, a result that can be replicated in other natural resource based productive sectors that are common in developing contexts.
