Research ArticleOpen accessEvery word in the titleDevelopment of Integrated Production Scheduling System in the Process IndustryMohamed K. Omar, Yasothei A.P. Suppiah, Siew C. TeoThis study introduces a three-level hierarchical production planning and scheduling approach developed and implemented in a resin factory. Our approach proposes at the first level a mixed-integer linear programming for solving the aggregate planning model. At the second level, a weighted-integer goal-programming model is developed to disaggregate the developed aggregate plans. A sequencing algorithm is developed for the third level … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,867 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRemoving Useless Productions of a Context Free Grammar through Petri NetMansoor Al-A'ali, Ali A. KhanFollowing the proposal for a Petri Net (PN) representation of the Context Free Grammar (CFG)[1], we propose in this paper, an algorithm to eliminate the useless productions of CFG. First the CFG is represented by a PN. Then, based on the reachability, an algorithm is developed to eliminate Useless-productions. The algorithm is analyzed and implemented in Pascal using examples of … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,674 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeasonal Pattern of Varroa Mite Infestation and Its Impact on Honey Production in Apis mellifera Beekeeping in Chitwan, NepalSujan Amgai, Kedar DevkotaHoneybee colony health and productivity are severely affected by infestations of Varroa mites, which have become one of the most significant threats to apiculture due to their role in colony weakening, reduced productivity, and increased colony losses worldwide. The study was conducted in Chitwan district to assess beekeepers’ perceptions on mite infestation in different seasons, its effect on honey production, … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 14 Aug 2026 · 1,245 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMethodology of the Development of Production Digital Twins Using a Simulation ExperimentSnježana Križanić, Neven VrčekThe simulation experiment evaluates whether the business process model accurately replicates real-world operations and whether the digital twin functions in real-time. A digital twin of a production business process is a virtual representation of its real-world counterpart. Its aim is to monitor the execution of the actual production business process in order to detect irregularities and production downtimes early and … …Journal of Computer Science, Vol. 21, Issue 6 · 13 Jun 2025 · 4,812 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of Temperature and pH for Protease Production from Some Bacterial Isolates of Mangrove WatersFeskaharny Alamsjah, Yorasakhi Ananta, Anthoni AgustienProtease enzymes are widely used in biotechnology to produce amino acids and peptides from high molecular substrates, as well as in the leather industry for wastewater treatment, textiles, pharmaceuticals, cosmetics, leather processing, and poultry industry. Indonesia's demand for protease enzymes is increasing. This study aims to optimize the temperature and pH for the production of protease from certain bacterial isolates … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 11 Sep 2024 · 4,427 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Age and Season on in vivo Embryo Production of Friesian Holstein CowsNurul Isnaini, Syafira Aldina Febrianty, Faizal Andri et al.Embryo transfer is one of the leading technologies that is now being applied in an effort to increase the population and productivity of dairy cattle in Indonesia. Several factors may affect embryo production including age and season. In this study, the effects of age and season on in vivo embryo production were evaluated on Friesian Holstein (FH) cows. A total … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 2 Mar 2024 · 5,461 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBioethanol Production from Graminoid Weeds in Bayero University Kano: A Potential Feedstock for Future Sustainable Aviation Fuel ApplicationsAdam Salihu Kila, Sa’idu Hassan Musa, Umar Aliyu Ahmed et al.This study evaluates the potential of selected graminoid weeds from Bayero University, Kano (BUK), Nigeria, as feedstock for bioethanol production. Ten (10) abundant weed species, including Cenchrus species, Cynodon dactylon, and Setaria barbata, were subjected to physicochemical pretreatment (ultrasonication, hydrothermal treatment, and enzymatic hydrolysis) followed by fermentation using Bacillus subtilis, Saccharomyces cerevisiae, and their co-culture. Pretreatment significantly enhanced reducing sugar … …Energy Research Journal, Vol. 15, Issue 1 · 15 Jul 2026 · 1,181 accessesView PDFCite
