The model of turbine mass flow characteristics is vital to simulate equipment and systems having a turbine, such as renewable energy power systems, air cycle refrigeration systems, power plants, and turbine engines. Existing empirical and partly empirical models of turbine mass flow...

This paper involves the multi-mode project payment scheduling problem with bonus-penalty structure where activities can be performed with several modes and a bonus-penalty structure exists at the deadline of the project. In the problem the decisions on when to schedule events and payments, the...

This paper involves the multi-mode project payment scheduling problem where the activities can be performed with one of several discrete modes and the objective is to assign activities' modes and progress payments so as to maximize the net present value of the contractor under the constraint of...
