As a policy we can experiment with different caps on total staffing. By simple arithmetic with 1,000 drawings to complete and a productivity of 1, 100 people should be able to finish the job in 10 months. There were twice that many people at the end of the last simulation, so maybe we can do better. We want to reformulate required workforce, but the current equation for this is already quite involved. To clarify things rename required workforce as indicated workforce. Now add in a new variable called required workforce.
indicated workforce will be used where required workforce used to be used and required workforce will be computed differently. Note that when you rename required workforce Vensim automatically makes sure it is renamed in the equations it is used in. Thus you only need to write new equations for:
indicated workforce = IF THEN ELSE(total workforce <
required workforce,
willingness to change workforce*required workforce +
(1-willingness to change workforce)*total workforce,
required workforce)
Units: Person
max workforce = 1000
Units: People
required workforce = MIN(max workforce,
required workflow/normal productivity)
Units: Person
max workforce is initially set very large to allow a non binding policy. If you simulate the model with these changes the same behavior is generated.
