Abstract
This paper proposes the quantitative model of resource reallocation with alternation of productivity. When the project progress is behind the plan, the project team plans crashing or fast tracking to recover the delay. Usually, the reallocated human resources of crashing plan is human who is in the same project or who has been in the same kind of project to avoid descent of the task productivity considering past accomplishment and cost of the human. However that information is insufficient to efficient crashing plan because the productivity of the human resources change with rejection time or project phase. Therefore, this paper proposes the quantitative method to make the crashing plan considering alternation of productivity.
