Earned Value Management is a critical project managementmethodology that evaluates project performance from cost andschedule viewpoints. The novel theoretical framework presented in thispaper estimates future performance of project regarding the past relativeinformation. It benefits from fuzzy regression (FR) models in estimationprocess in order to deal with the vagueness and impreciseness ofre...
Earned value management (EVM) has prepared some methods to forecast final costs of projects. These methods were not developed since the start of formation and were gradually completed, of course with one exception that is its authenticity, they are still remained unchanged. At the present time EVM guide does not apply from schedule indices to forecast schedule for completion of project and ...
In the last decade, theory of constraint application in project management lead to make a new approach for project scheduling and control as a critical chain. In this paper, a multi-objective optimization model for multi-project scheduling on critical chain is investigated. The objectives include time, cost and quality. In order to solve the problem, a Simulated Annealing algorithm is developed...
in the early stages of a construction project, the reliability and accuracy of conceptual cost estimates are major concerns for clients and cost engineers. previous studies applied scoring methods and established common rules or mathematical methods to assess the quality of cost estimates. however, those approaches have some limitations in adapting to real-world projects or require understandin...
چکیده در این پژوهش بااستفاده از تفکر سیستمهای پویا به مدل سازی ریاضی سیستم زنجیره تأمین ارتباط ثابت در شرکت مخابرات ایران پرداخته ایم و بدین منظور از اطلاعات موجود و مستند شرکت مخابرات ایران از سال 1384 تا 1391 و نتایج شبیهسازی مدل پویاییهای سیستم تا سال 1404 استفاده کرده ایم. برای تجزیه و تحلیل و تعیین ماهیت سیستم، از مفهوم مدل سازی ریاضی سیستمهای پویا استفاده کردیم. نتایج مدل سازی نش...
