In this paper, we consider the problem of stochastic project network when some or all activities are interrupted. An approach has been built to schedule the critical activities, by constructing some expressions based on the project lateness costs due to the interruption activities. Two simple example are presented to validate our approach.

Key words: Project Management, Project scheduling, Stochastic activity duration, Stochastic PERT.

The process of regression analysis is based on a number of basic assumptions, and if one of these assumptions is not available, this will lead to obtaining inaccurate results, and the most of these assumptions is homoscedasticity, violating this assumption causes a problem of heteroscedasticity of the random error variance the, which may come from different variances This cause to misleading and inaccurate decisions.

      Recently Econometric models received attention, especially limited regression models, which contain specific response variables and several repeated observations within a certain range, including Tobit models and also considered imitations of the Censored Regression Model. Problem arise

All water treatment centers in Iraq operate according to the standards specified in the legal regulations. Therefore, periodic evaluations must be conducted to study and analyze the quality of the outputs of these centers. The research used the two-parameter Weibull distribution to evaluate the reliability of turbidity removal and residual chlorine in the water at the Rashidiya water center in Baghdad, Iraq. The distribution parameters were estimated using the Maximum Likelihood method with the Matlab 2022 program, and the chi-square test for Goodness of Fit was used at a significant level of 0.05. The study found that the mean (and median = 9 NTU) of turbidity values were 9.47 NTU, which is within the permissible limit, and the mean (an

The semiparametric regression models have received a lot of attention from researchers recently because it combines parametric and nonparametric methods, it is one of the advanced topics in data analysis for various studies, which aims to find the best capabilities and a high level of efficiency.

One of the most important semiparametric regression models is the partial linear regression model (PLM), which consists of a parametric component and a nonparametric component, for the purpose of estimating the parametric component, the difference method will be used to remove the nonparametric component.

When the analysis hypotheses of the parametric component are not fulfilled, it will suffer from several problems, the most imp

Count data represents a number of defined events that occur within a specific time frame for explanatory variables in the form of integers, and discrete distributions are among the probability distributions that use count data. The most famous of these distributions is the Poisson distribution. However, sometimes a change in the pattern of the random variable period may occur, such as the absence of the zero value, which requires finding a distribution that fits such a change, and that is the Zero Truncated Poisson Distribution (ZTPD).

       This research aims to find a suitable model for the effect of non-zero value of data on any phenomenon and to use it to build a Zero Truncated Po

The study aimed to take austerity measures to address the public budget deficit in Egypt, as the public budget deficit is one of the most important economic problems that affects the public financial situation, and the Egyptian economy does not differ from the rest of the world’s countries in terms of the increasing public budget deficit. The analytical approach was used to show the impact of the financial austerity policy on the  public Budget deficit. Egypt succeeded in adopting a policy of financial austerity, as after several years of slow growth and weak economic performance, the Egyptian economy began to recover. The financial situation improved as a result of the implementation of the value-added tax and reductions in energ

The research endeavors to harness the benefits stemming from the integration of constraint theory into construction project management, with the primary goal of mitigating project completion delays. Additionally, it employs fuzzy analysis to determine the relative significance of fundamental constraints within projects by assigning them appropriate weights. The research problem primarily revolves around two key issues. Firstly, the persistent utilization of outdated methodologies and a heavy reliance on workforce experience without embracing modern computerized technologies. Secondly, the recurring problem of project delivery delays.

Construction projects typically encompass five fundamental constraint types: cost restrictions, t
