Schedule Risk Analysis by Different Phases of Construction Project Using CPM PERT and Monte Carlo Simulation
Construction project is an important activity along with the increasing need of infrastructure and residential building. Construction projects with different investment value and complexity level affect the completion duration of construction work. The higher the value or the more complex the building, the longer time required to accomplish the construction project. During the construction process, it is possible to find risks both from internal and external management which potentially cause project overdue that will lead to cost overruns. This study focused on assessing and managing schedule risk in three main phases of construction project, such as: feasibility study, design, and construction. A certain sample of residential building project was choosen as study case. In this study, mathematical approaches are used by performing CPM PERT and Monte Carlo simulation method. The results of this study can be used to help project managers to minimize potential risks by projecting simulation results and to assess if a project can be completed in timely manner according to given schedule.

TIME OPTIMIZATION USING CPM, PERT AND PDM METHODS IN THE SOCIAL AND DEPARTMENT OF KELAUTAN BUILDING DEVELOPMENT PROJECT GRESIK DISTRICT
Planning a project there are many important things that affect the success and smoothness, one of which planning time implementation of the right and efficient work. The way to overcome the problem is by using several methods such as CPM (Critical Path Method) PERT (Project Evaluation and Review Teqnique) PDM (Precedence Diagram Method) From the calculation result show that the duration of project completion using CPM method is 57 weeks, project completion duration using PERT method is 78 7.5 weeks with the probability of achieving project completion time target is 99.87% and project completion duration using PDM method is 30 weeks. So the method that best suits the Social Service Development Project and the Office of Marine Gresik Regency is the PDM method because the PDM method is capable of producing shorter project completion periods than the CPM and PERT methods of 30 weeks.

The Impact of Task Methodology Fit on CPM/PERT Diagramming Performance: An Experimental Investigation
We propose to investigate students' performance as they construct CPM/PERT network diagrams. Our investigation will have two parts. The first is comparison of performance of students using one of two methodologies for constructing the diagrams we want to understand which methodology is more efficient and effective. The second aspect will entail investigation of the impact of the interaction between methodology and task features in the construction of these diagrams. Our two measures of performance, efficiency and effectiveness, will be captured by measuring the time spent constructing diagram and the accuracy of diagram construction as denoted by a grade assigned to the outcome. Our tasks will vary according to the information presented to students for constructing the diagrams. We will conduct a 2x2 factorial experiment with students and analyze our experimental data using a 2 way MANOVA. Our expected contributions include recommendation of alternative methodologies for teaching students how to construct network diagrams as well as specific task features for each methodology. We also hope to gain insights on students' relative preference for the methodologies.
