Hybrid knowledge-based expert system and multi-criteria analysis for minimizing erosion and sedimentation due to stormwater in Malaysian construction sites

摘要

Malaysia is located in a tropical zone wherein heavy rainfall occurs in all seasons of the year. Land clearing andnearthwork activities combined with heavy rainfall and the widely varied topography can result in severe soil lossnthat shall eventually be deposited into the adjacent water bodies via stormwater. Recently knowledge-based systemsnhave been used in many fields especially when human expertise and data are limited. In the current study, anhybrid knowledge-based expert system and multi-criteria analysis (MCA) were developed to minimize erosionnand sedimentation due to stormwater in Malaysian construction sites. This system called the Multi-criteria Erosionnand Sediment Control (MCESC) system. The role of MCA is to identify the best stormwater control measurenbased on specified criteria and the criterion’s weight. Data from road construction project in Permas Jaya, JohornBahru State, Malaysia has been utilized for testing the MCESC system’s functionality in solving real erosion andnsediment control problem. The MCESC system can be used by engineers, contractors, and decision makers tondevelop erosion and sediment control plan and environmental management plan for any construction site innMalaysia
