Scheduling a cellular manufacturing system with GA
2002
The flexible manufacturing cell scheduling problem is considered with a multi-objective approach, pursuing together makespan minimisation and the in process job wait minimisation. The formulation of the scheduling problem is discussed, analysing how to generate well suited sequences, like generalised permutation sequences, and the proper construction of a JIT timing of activities. An evolutionary sequencing algorithm based on both classic genetic operators and hybrid operators is then proposed. The hybrid operators have been introduced to construct highly fit initial population, to perform periodically a local search on the population and to maintain enough genetical diversity in the actual…
Différents modes de production
2012
Les productions générées par les exploitations agricoles sont organisées en système de production qui désigne « l’ensemble structuré des facteurs de production combinés entre eux pour assurer une production végétale et/ou animale en vue de satisfaire les objectifs de l’exploitant agricole ». Les systèmes de production sont souvent décrits par les OTEX (orientations technico-économiques des exploitations) sur une base économique de classification, mais il existe égalementdes descriptions fonctionnelles fréquemment utilisées parles instituts techniques sur la base des facteurs de production et de leur combinaison. Dans les exploitations françaises, la production d’herbivores (bovins, ovins, c…

Fuzzy logic controller and game theory based distributed energy resources allocation
2020
Energy management and demand control through conventional energy generation sources are challenging for energy providers. Distributed energy resources (DERs) allocation near load centers may provide a suitable solution. The main contribution of the paper improves the voltage profile and reduce the active and reactive power losses in the distribution network. DERs are integrated with IEEE 33 bus system using fuzzy logic controller (FLC) and game theory for two different cases with unity and 0.9 power factor (PF) and compares with conventional methods of integration (i.e., modified novel method, power loss sensitivity method, voltage sensitivity analysis method). The capacity of DERs is optim…

Potential production of biogas from prinkly pear (opuntia ficus-indica L.) in sicilian uncultivated areas
2017
The aim of this work is to evaluate the potential production of biogas and, indirectly, biomethane or electric and thermal energy, from prinkly pear (Opuntia ficus-indica L.), to be grown in a part of Sicilian uncultivated areas and co-digested together with the available livestock manure and slurry. In order to increase the Renewable Energy Sources (RES) and reduce the dependency from fossil ones, the conversion of biomass into biogas through Anaerobic Digestion (AD) process is paramount for producing biomethane, to be used as fuel for means of transport and agricultural machines or heating, or electric and thermal energy through Combined Heat and Power (CHP) plants. Moreover, the digestat…
INTEGRATED SYSTEMS FOR PLANNING AND RESOURCES MANAGEMENT IN COMPANIES
2014
Information is one of the most valuable resources of a company, since with it and around it the whole set of business processes unfold within companies. Till using internet companies were eager to find information that was necessary for the functioning and development of the company; now things have changed radically: the information is abundant and is provided through all possible channels; today, in order to thrive you have to „choose" and to filter the information to remain competitive on the market you are active on. The performance of an enterprise is influenced by its ability to adapt itself to the environment, by the effectiveness of its actions in capitalizing opportunities, by its …

Comparative study between different methods for the efficiency of the production activity in the wood industry
2017
Generally speaking, the quality and cost of goods and in particular of the wood products is a decisive condition in their sales on the market, attracting buyers to satisfy their wishes and requirements. Starting from the general idea, by which it is considered that the manufacturing activity is effective if production is obtained at maximum quality with a low (minimum) cost, or when the revenue from the sale of products exceeds the market expenditure which is necessary to achieve it, this research article aims to study ways to make production more efficient by methods which could also be applied in the wood industry, by presenting a comparative study on production optimization methods in th…
The beta-delayed proton and gamma decay of 27P for nuclear astrophysics
2013
The creation site of 26Al is still under debate. It is thought to be produced in hydrogen burning and in explosive helium burning in novae and supernovae, and possibly also in the H-burning in outer shells of red giant stars. Also, the reactions for its creation or destruction are not completely known. When 26Al is created in novae, the reaction chain is: 24Mg(p, γ) 25Al(β +ν) 25Mg(p, γ) 26Al, but this chain can be by-passed by another chain, 25Al(p, γ) 26Si(p, γ) 27P and it can also be destroyed directly. The reaction 26mAl(p, γ) 27Si∗ is another avenue to bypass the production of 26Al and it is dominated by resonant capture. We find and study these resonances by an indirect method, throug…
