2. (18 points) There are six work departments in one section of a manufacturing company: Heat Treatment
(DI), Printing (D2), Milling (D3), General Machining Area (D4), Cooling (D5) and Shipping (S). The
activity relationships between departments are shown in the following table:

Construct a block layout by using the graph-based method. Using the following closeness rating
values for different relationships: A=10000, E=1000, I=100, 0=10, U=1, X=-10000.

4. {M points} Suppose the following layout is provided as the initial layout (each square is It] K 10} to
CRAFT. The flowvhetween matrix is given as follows. (All the cg values are equal to LB] Flow-Between Matrix {1} {4 points} Given the above data and initial layout, which department pairs will not be considered for
exchange? {2} {t5 points} Compute the estimated layout cost assuming the departments A and E are exchanged. {3} {I'll points} Compute the actual layout cost once the ASLB exchange is made.

5. (20 points) Three classes of products (A, B and C) are to be stored in the warehouse depicted in the
figure below. The warehouse consists of storage bays of size 10'x10'. Product storage requirements
are 6 bays for A, 2 bays for B, and 8 bays for C. Fifty percent of the shipment has to go through dock
1, and the other shipments are evenly distributed between docks 2 and 3. All products require the
same number of trips from/to storage (dock) per day.
(1) (5 points) Formulate the problem using the warehouse layout model.
(2) (15 points) Recommend a layout that minimizes travel distance.

6. (20 points) There are 6 departments in one section of a manufacturing company: Heat Treatment (HT),
Printing (P), Milling (M), General Machining Area (MA), Cooling (C) and Shipping (S). The available
space is 10 *6 ft. The from-to chart is as following:

(1) (7 points) Construct a layout using the given unit block layout using the algorithm of
BLOCPLAN. The layout should have two bands. (round to two decimal places)
(2) (13 points) Calculate the flow cost of the layout (All the c, values are equal to 1.0).
