This paper is a short survey about the main fuzzy Petri net models which have been recently developed. We focus on the applicability of such approaches in the eld of manufacturing systems and factory automation. We also point out the main issues concerning the consistency of Petri net theory and these models. 1.1 Why Fuzzy Petri nets are useful for CIME? Factory automation has been addressed at...

ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3  in 2007 to 85 million  m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...

one of the most important steps of agaricus bisporus production is casing. in this step a layer of soil is added on top of compost. peat is the most suitable casing soil for a. bisporus production. the lack of peat in iran is one of the major problems in a. bisporus production for mushroom producers. it seems that peat can be replaced by spent mushroom compost (smc). in order to study the possi...

With the unit interval [0,1] as the truth value table, Chen and Wupresented the concept of  possibility computation over dcpos.Indeed, every possibility computation can be considered as a[0,1]-valued Scott open set on a dcpo. The aim of this paper is tostudy Chen-Wu's duality on quantale-valued setting. For clarity,with a commutative unital quantale $L$ as the truth value table, weintroduce a c...
