  This paper proposes an integrated approach of the earned value management and the risk management for predicting of project performance including cost and duration of estimate at completion. In spite of the abilities of earned value management technique in estimating the project future performance merely based on its past, it cannot consider the environmental change or other elements which effect on the future performance of the project. Unlike the earned value management, the risk management technique looks to the farther horizons and deals with the evaluation of the project performance by recognizing the failure modes. In this paper we intend to present the future performance index in combination with the earned value management current indices for better prediction of the projects’ future performance. These indices are determined under real-life and uncertain conditions using the fuzzy approach. In the end, the performance of the proposed method is evaluated by a numerical example. The results show that the consideration of the risk evaluation index improves the prediction of cost and time of projects' completion in the value management model. Manuscript profile

  Taking attention to reliability and maintenance management conception has substantially significantly increased over the recent decades. This paper proposes and integration of DATA MINING, Fuzzy DEMATEL, and FMEA technique in order to improve the reliability and effectiveness of maintenance management in Shazand Petrochemical Company. Firstly, the most critical cluster is selected among final clusters obtained from software by utilizing DATA MINING technique. Secondly, Fuzzy DEMATEL technique is used to identify a collection of most critical and most effective equipment of critical cluster under fuzzy condition. Finally, the FMEA and FTA techniques applied to identify the risks numbers and the main causes of the failure and then the solution will be proposed to solve the problems and improve the system.

  In the present paper, the main purpose is estimated path of crack growth under multi-axial loading. So, used plate with a center rectangular notch that has an initial crack with 5 mm length and 〖-55〗^°angle. At the First, has been obtained stress intensity factors of failure mode I and II by using ABAQUS software. Next has been calculated equivalent stress intensity factor and estimated path of crack growth by using the maximum environmental stress method. This trend has been continued to finish failure.

  In today's competitive world, various organizations have been constantly concerned with improving production processes as a way to enhance product quality.  Experiment design is a statistical quality control method leading to increased product quality, and thereby, enhanced manufacturing productivity. The present study set out to identify and prioritize the defects in industrial paints produced by Partofooldam industrial paint manufacturing company through failure mode and effects analysis (FMEA) and to determine optimal value levels for the identified effective factors using Taguchi Orthogonal Array Method. To serve the purpose, six trihedral factors and one dihedral factor were defined and the L18 array was selected for designing the required experiments. The findings indicated that the best paint quality was obtained in the experimental condition with over 10 micron granulation, peak metal temperature (PMT) of 232°C, high quality pigment, resin content of 55%, catalyst content of 4.1%, using medium quality plate and maximum content of additives. The effectiveness of the proposed method was determined by comparing the risk priority number (RPN) in FMEA before and after implementing Taguchi Method which showed a 19 point drop in the mean RPNs for all the identified problems. The results verified the impact of Taguchi’s method on reducing product failure risk and enhancing product quality.   Manuscript profile

  Pipe behavior under fault displacement is complex. In the past earthquake fault displacement of 2.1, 3 and 4 meters has been reported. Literature review shows understand failure modes of buried pipelines subjected to big fault displacement, is a challenge. In this paper, the influence of the thickness of the pipe on the response of the pipe under the fault displacement greater than 1 meter is studied. The quasi-static analysis by taking into pipe-soil interaction, by finite element simulation was performed with the ABAQUS software. Pipe and soil Dimensions and material properties of the soil and pipe is fixed in all analyzed. The fault displacement (0.2 to 3 meters) and the pipe thickness (from 8.2 to 20 mm) variable parameters of this article. For variable displacement faults and the thickness of the pipe, the pipe deformation After removing the fault, the thickness of the pipe and the amount of displacement of the fault on the behavior of pipe strain exists in the pipeline wall is extracted and discussed is located. The displacement of less than 1 meter, the pipes like the letter S and local buckling occurs in the pipeline. The displacement of 1.5 meters and more like the letter Z-pipe deformation and wrinkling occurs in the pipeline. The displacement of more than 1.5 meters, distortion, and wrinkling pipe is deformed. The displacement of more than 1 m by increasing the thickness of the pipe, the strain is reduced. Change the thickness of the pipe, the pipe failure mode changes. Manuscript profile

  This study was conducted with the goal of investigating the amount of Chrome heavy metal in Firouz Abad river of Tehran. For this purpose, sampling from water was conducted by determining 5 measurement stations in the river path in the spring, summer and autumn of 2007. Analysis of samples was performed using Atomic Absorption method. The results of this study show that the levels of chrome metal measured in the third, fourth and fifth stations with the averages of 0.503mg/l, 1.29mg/l and 2.62mg/l, respectively are above the allowed level of chrome in the run-off determined by Environment Preservation Organization (0.5mg/l). In order to estimate the level of environmental risks of chrome in the environment of the affected area, the Environmental Failure Modes and Effects Analysis and its effects on environment was used. For this purpose, a table was first designed based on each station in which chrome concentration was graded within the scores span of 1 to 50 from the respects of risks severity and possible consequences. Then, Risk Priority Number (RPN) was calculated for each station from the product of risks severity in possible consequence. In the stations in which the level of chrome heavy metal was above the standard level, some measures were suggested for minimizing RPN. In this study, the level of environmental risks of this metal was estimated in 5 stations based on RPN as follows: RPN of first station = 2 < RPN of second station = 10 < RPN of thied station = 30 < RPN of forth station = 200 < RPN of fifth station = 450 Due to irrigation of agricultural lands by this river especially vegetable farming and growing summer crops in south of Tehran, the excess concentration of chrome has increased significant absorption of the aforesaid heavy metal in plants which its consequence is the entrance of this metal to food chain and its bad effects on human.
