Multi-mode Resource Constrained Project Selection and Scheduling Considering the Reinvestment Strategy in a Flexible Time Horizon

Many operations research problems in project management, manufacturing, and elsewhere require the generation of specified sets of activity networks for purposes of testing proposed solution approaches. To date, single-network generators have been used for the resource-constrained project scheduling problem (RCPSP). Since the first single-network generator was proposed in 1993, several advances ...

Project scheduling problem is mainly to determine the schedule of allocating resources in order to balance the total cost and the completion time. This paper chiefly uses chance theory to introduce project scheduling problem with uncertain variables. First, two types of single-objective programming models with uncertain variables as uncertain chance-constrained model and uncertain maximization ...

A common problem faced by organizations is how to select and schedule an optimal portfolio of projects subject various constraints, such as a limited budget. This known the project selection scheduling (PPSSP). Despite widespread nature this problem, no existing model adequately addresses sufficient set characteristics that arise in real-world problems. One contribution article proposal novel, ...

In recent years, more researchers have devoted their attention to the resource-constrained multi-project scheduling problem, resulting in a growing body of knowledge on solution procedures. A key factor comparison these procedures is availability benchmark datasets that cover large part feature space. Otherwise, one risks conclusions from experiments sets do not hold when they are repeated diff...
