You manage the production process in the high-tech facility of Dale Computers Inc. The facility consists of three different assembly lines (1, 2, 3) making two different products, X and Y. Assembly Line 2 is dedicated to the assembly of product X, and assembly line 3 is dedicated to product Y. Assembly Line 1 can assemble both the products. The production process begins with the procurement of raw materials from suppliers. Next, the raw materials are processed into six independent subassemblies, AF, in separate work areas within the facility. Each product is then assembled from these subassemblies in one of the assembly lines. Product X involves the assembly of subassemblies A, B, C, and E. Product Y requires that subassemblies B, C, D, E, and F be assembled. Subsequent to assembly, each product is finished, customized (painted and other options added), packaged and shipped. Current trends indicate that 20% of product X and 50% of product Y are customized.

Following are the capacities of the work areas producing the subassemblies:

Subassembly Type	Capacity (Units/Week)
A	2500
B	2400
C	2400
D	2250
E	3400
F	1200

The annual demands for the products are as shown below:

Product	Sub-assemblies required for one unit of product	Annual Unit Sales
X	2 of A; 1 of B, C, E	52,000
Y	1 of B, C, F; 2 of D, E	52,000

The capacities of the assembly lines and the finishing, packaging and customizing areas are as given below:

Assembly line 1 1200 units/week Finishing 2500 units/week

Assembly line 2 500 units/week Customizing 850 units/week

Assembly line 3 600 units/week Packaging 3000 units/week

Notes: (1) Assume 52 operating weeks/year.

(2) Plan production to meet the demand (do not overproduce).

What is the current bottleneck in the system? Identify the top three areas that are candidates for becoming a bottleneck area of this system as demand increases (assume proportionately). Show your calculations.
