The article considers the model of time planning in strategic goal programs of innovative development of complex, large-scale systems. In practice, a creative project has conjunctive logic, and we describe it in the space of time-cost-reliability variables. The time indicator of the goal program (large-scale project) is found from the solution of the optimization problem, for which we use an effective method. The Weibull distribution gives the activity reliability index. In this case, we obtain a lower bound on the reliability indicator of the project as a whole. The table provides the results of numerical calculations for the test example.
