Inventory simulation with sinusoidal orders
Information
Seasonally Fluctuating Customer DemandThe third simulation involves seasonal fluctuation of customers with a capacity limit of 1200 items/week in the factory. The customer demand remains always below the manufacturing capacity limit; nevertheless, the manufacturing site must operate at its capacity limit for certain time periods, while at other times, it runs at 20% of its capacity only.
Simulate the model across 120 weeks, and plot on one graph the incoming orders and the production flow in the factory and on a second graph the levels of goods in retail, distribution, and the factory as functions of time:
