Research ArticleOpen accessIn the keywordsModeling and Simulation of Projects with Petri NetsS. Kumanan, K. RajaTraditional project management tools and other revised tools are limited in representation of the problem and in dealing situation dynamically. This paper details the use of Petri nets as a graphical and mathematical modeling and simulation tool in project management. In this context, the benefits of Petri nets are indicated. A Petri net aided software, a PETRI-PM is developed to … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,377 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Environmental Risk on the Financial Structure of Oil and Gas ProjectsBagilya Karsybayeva, Alberto De MarcoThe risk profile of a Build-Operate-Transfer (BOT) project affects its debt service ability. In particular, the total risk profile of an oil and gas project is heavily influenced by its environmental risk exposure. However, this risk is often not given a considerable weight in risk analysis, resulting in underestimation of project’s total riskiness and consequent overestimation of the debt capacity. … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 22 Jan 2013 · 7,195 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn Calculating Activity Slack in Stochastic Project NetworksGary MitchellProblem statement: Identifying critical tasks in a project network is easily done when task times are deterministic, but doing so under stochastic task times is problematic. The few methods that have been proposed contain serious drawbacks which lead to identifying critical tasks incorrectly, leaving project managers without the means to (1) identify and rank the most probable sources of project … …American Journal of Economics and Business Administration, Vol. 2, Issue 1 · 31 Mar 2010 · 8,227 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImproving the Accuracy of Effort Estimation through Fuzzy Set Representation of SizeCh. Satyananda Reddy, KVSVN RajuProblem statement: The precision and reliability of the effort estimation is very important for the competitiveness of software companies. The uncertainty at the input level of the Constructive Cost Model (COCOMO) yields uncertainty at the output, which leads to gross estimation error in the effort estimation. Fuzzy logic-based cost estimation models are more appropriate when vague and imprecise information was … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the keywordsResource Leveling Using Petrinet and Memetic ApproachK. Raja, S. KumananThe problem of scheduling activities dynamic for a project, within the available resources and adhering to precedence relationships is NP hard combinatorial. Traditional approaches and their extensions are limited in application for simultaneous scheduling of resources with leveling. Considering the need for improved modeling and scheduling techniques, this paper proposes the use of Petrinet based approach aided by memetic algorithm. … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Algorithmic Cost Estimation Model Based on Soft Computing TechniqueIman Attarzadeh, Siew Hock OwProblem statement: Software development effort estimation is the process of predicting the most realistic use of effort required for developing software based on some parameters. It has always characterized one of the biggest challenges in Computer Science for the last decades. Because time and cost estimate at the early stages of the software development are the most difficult to obtain … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,927 accessesView PDFCite

In particular, discrete-event simulation is widely used in a wide variety of fields, such as industry and production, finance and economics, or even health and services. In addition, the conduct of a simulation project is of extreme importance, in order to carry … …Journal of Computer Science, Vol. 19, Issue 8 · 15 Jul 2023 · 5,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Equation Model (SEM) for Evaluating Factors Affecting ICT4D Project SuccessHouda Fakhkhari, Bouchaib Bounabat, Maria BennaniInformation Communication Technology for Development (ICT4D) enables organizations to transform and evolve. Despite the contributions of methodologies and models for project management, the number of failed ICT4D projects remain high; as a consequence, researching crucial success factors of ICT4D projects remains an important matter for practitioners and researchers. Studies and researches on factors impacting ICT4D projects' success are various, fragmented … …Journal of Computer Science, Vol. 17, Issue 8 · 8 Sep 2021 · 7,080 accessesView PDFCite
Case ReportOpen accessIn the abstractLessons Learned: Barriers to Hemoglobin A1c Monitoring in Rural Northern TanzaniaAndrea Fortson Knopp, Erika Metzler SawinIn sub-Saharan countries, Non-communicable Chronic Diseases (NCDs), including diabetes, are on the rise. Glycated hemoglobin (HbA1c) is a Point Of Care (POC) diagnostic tool for diabetic monitoring that is unavailable in many resource-constrained environments worldwide. Theoretically, HbA1c measurement is practical in these settings because fasting is not required, the test is not generally repeated before 120 days and travel time … …International Journal of Research in Nursing, Vol. 11, Issue 1 · 8 Jan 2021 · 6,228 accessesView PDFCite
