Hybrid genetic algorithm based on synthetical level of resource conflict for complex construction project scheduling problem

A hybrid genetic algorithm based on synthetical level of resource conflict for solving complex construction project scheduling problems is proposed, which combines rules-based heuristic with genetic algorithm based on synthetical level of resource conflict, which is used to guide the code, crossover and mutation of genetic algorithm. Also, Researches are made in these aspects such as decomposition method of complex construction project scheduling problem, genetic coding, generating of initial population, crossover and mutation of genetic algorithm. Numerical computation results of different scale problems show that the algorithm has excellent performance for construction project scheduling problem and is suitable for larger-scale construction project scheduling problem with serious resource conflict.
