We assume the resource is released at defined time points and at defined quantities. We also assume that the activity costs are charged once they are completed. Our aim is to minimise the project completion time. We formulate the problem as a pure integer programming model and show that it is strongly NP-hard. We find lower bounds by pure and mixed integer linear programming relaxations of the model and develop three heuristic procedures based on those relaxations. The results of our computational study have revealed the satisfactory performances of our lower bounds and heuristic procedures.eninfo:eu-repo/semantics/closedAccessProject SchedulingMulti-ModesNon-Renewable ResourceInteger ProgrammingLinear Programming RelaxationHeuristicsArticle10.1504/EJIE.2015.0703222-s2.0-84936745506
