This research, prepared a calendar forecast rainy days for planning construction in monthly format, which resulted in a strike to perform construction, not on the basis of a strike. This applied research criteria of the Federal Highway Administration to stop working (FHWA) country United States in many works by this research proposed a calendar that chances of rain in area 95 90 80 70 percentage 60 studies, amphur Muang, Phitsanulok province year 2556. with the application of air-data generator model success.Semiparametric format Weather Generator (SWG.) by virtue of statistical methods to analyze data from the daily rainfall measurements by rain gauge stations on the ground from 63 up to the area around 2494 2556. study of 8 stations. Inverse Distance Weighting method, using techniques (IDW) in spatial rainfall interpolation to the center of the study area, on district-level scope and test techniques for planning and Program Evaluation Review Technique way (PERT) Monte Carlo Simulation (MCS) and how cumulative table from calendar to rainy days with actual construction plans from three case studies to compare the expected period of the project is completed.

This research was conducted calendar day rainfall forecast for the planned construction of a monthly result of a strike makes the construction process did not meet the criteria of a strike. This research application criteria strike of the Federal Highway Administration (FHWA), United States in various categories. This research presents a calendar chance of rain 95 percent 90 80 70 and 60 in the area of ​​the city. Phitsanulok year 2556. With the application of modeling weather data generator packages. Semiparametric Weather Generator (SWG). Using statistical methods to analyze data daily rainfall measurements from ground-based rain measuring station by 63 years from 2494 to 2556. The area around the station number 8. Using techniques. Inverse Distance Weighting (IDW) to estimate the amount of rain to the center of the study area, the spatial idea of ​​the scope of government at the district level. And bring to trial the technique planning with Program Evaluation and Review Technique (PERT) Monte Carlo Simulation (MCS) and table collection from the expected calendar days of rain. Construction plans with real case studies of three projects to compare the duration of the project is expected to be completed.

This study predicts rain for calendaring construction planning in monthly pattern ที่ส่งผลให้เกิด strike makes the construction according to the strike.). This research applied the absence of Federal Highway Administration (FHWA) the United States in different categories. The research presented in this calendar was 95 percent chance rain 90 80 70 60 in the study area, district and city. Phitsanulok year 2556. Application of weather data package Semiparametric Weather model birth Generator (SWG). By using statistical methods in the analysis of the data of daily rainfall measurement with the measuring station rain region ground 63 years. Since the year 2494 to 2556. Around the study area of 8 station. Using techniques Inverse Distance Weighting (IDW) in the estimation of rainfall spatial with the center of the study area to think from the scope of the district. The experimental techniques of planning method Program Evaluation and Review Technique (PERT) Monte Carlo Simulation (MCS) and how the table collection from calendar is estimated on a rainy day. With the planning and construction of a 3 project. To compare the time expect the project had been completed.
