Suppose the storage area for a warehouse is as shown below. Two input$/$output points serve the storage

area, with the overall trip activity being about $50\%$ for each dock. All movement is in full$-$pallet

quantities. The storage area is subdivided into $1010ft$ storage bays. Three classes of products $($A$,$ B$,$ C$)$

are to be stored. Class A items represent $25\%$ of the input$/$output activity and have a dedicated$-$storage

requirement of $5$ storage bays; class B items generate $55\%$ of the trip activity and have a dedicated$-$

storage requirement of $10$ storage bays; class $C$ items generate $30\%$ of the input$/$output activity and

have a requirement of $4$ bays. Indicate the optimal warehouse layout, showing all supporting

calculations.

Hint: assume the total number of trips $N=100$ trip
