A Multi-Mode Resource-Constrained Project Scheduling Model with Bi-random Coefficients for Drilling Grouting Construction Project

The aim of this paper is to deal with the multi-mode resource-constrained project scheduling problem under bi-random phenomenon in a practical large-scale water conservancy and hydropower construction project. A multiple objective decision making model with bi-random coefficients in the constraint is first proposed for practical drilling grouting project scheduling problem to cope with hybrid uncertain environment where twofold randomness exists. Subsequently, the chance constraint operator is employed to handle bi-random variable. Furthermore, particle swarm optimization algorithm is applied to search for the optimal solution. The results generated by computer validate the effectiveness of the proposed model and algorithm in solving large-scale practical problems.
