The resource-constrained project scheduling problem seeks to find an appropriate sequence for performing the activities of a project such that precedence constraints in the project network and various types of resource limitations are satisfied simultaneously, while specific performance criteria—such as project completion time, activity execution costs, the number of delayed activities, and so on—are optimized. With the development of this problem in recent years, an activity can be performed in several possible modes (for example, each activity can be executed within a specific duration and with a certain amount of renewable or non-renewable resources). This new concept has led to the development of one of the most general forms of scheduling problems, known as the multi-mode resource-constrained project scheduling problem. On the other hand, as humanity steps into the third millennium, it faces numerous environmental and ecological issues every day. The effects of environmental pollution and the destruction of natural resources threaten natural life more than ever. Therefore, preventing the destructive impact of unbalanced economic and industrial activities on the environment, as well as restoring and repairing it, have become major concerns in modern life. Given the current importance of green criteria, the aim of this paper is to mathematically model and optimize the multi-mode resource-constrained project scheduling problem while considering gas emissions. After modeling the problem as a mixed-integer programming formulation, the results were analyzed and evaluated.
