Using the model from class:

Identify the main loops and main state variables that govern the system dynamics.

Explore the behavior of the system for the following versions of "Delays Fixed":

a$.$ DELAY FIXED$($ ORDERS TO PROVIDER, Delivery delay days, $0)$

b$.$ DELAY FIXED$(0,$ Delivery delay days, Avg Daily Sales$)$

c$.$ What do the resulting dynamics mean? Draw and explain the meaning of the existing formulation of the "Delay Fixed" included in the Vensim model provided ${?}^1.$

For fixed DELIVERY DELAY DAYS, examine the role of ORDER FACTOR FROM DAILY SALES $($alpha$),$ and ORDER FACTOR FROM STOCK DEFICIT $($beta$)$ on the dynamics of the process. Draw a state space diagram that shows values of alpha $(x$ axis$),$ and beta $($y axis$)$ versus warehouse stock cycle period $($z$1)$ and amplitude $($z$2)$

Which parameter constellations lead to strong oscillations? Conversely, which combinations reduce or eliminate oscillations?

What would be the most convenient delays days for optimizing warehouse stock?

Analyze the effect of alpha, beta, and delays on ACCUMULATED SALES. Which parameter is most influential?

Find an "ordering policy" which requires the smallest possible storage capacity but, at the same time, ensures that always all customer demand are fulfilled even for moderate random fluctuations of sales.
