Ant colony algorithm for project scheduling problem under flexible work-hour constraints
柔性工时约束下项目调度及其蚁群算法

A new mathematical model for software engineering project scheduling was proposed. The model took into consideration the over-time of software engineers, which was regarded as a flexible work-hour constraint. The project human resources were analyzed in detail. As a type of special renewable resource, the human resource was added as a new constraint to the traditional resource constrained project scheduling problem. An ant colony algorithm based on parallel schedule generation scheme was suggested to solve this new flexible work-hour constrained project scheduling problem, and an instance was used to verify and analyze the solution.
