Chapter 20 Constrained Optimization: Multiple Internal Constraints Fisher Company produces two types of components for airplanes: A and B, with unit contribution margins of $400 and $600, respectively. The components pass through three sequential processes: cutting, welding, and assembly. Data pertaining to these processes and market demand are given below (weekly data). Resource Available Resource Usage (A) Resource Usage (B) Resource Cutting 300 machine hours Six hours Ten hours Welding Six hours 308 welding hours Ten hours Assembly 400 labor hours Four hours Ten hours Market demand (A) 50 One unit Zero units Market demand (B) 40 Zero units One unit Required: 1. Express Fisher Company's constrained optimization problem as a linear programming model. If an an answer box does not require an entry, enter "0" for your answer. Objective function: Max Z = $400 A + $600 B Internal constraints: BS (cutting) A+ (welding) (assembly) External constraints: Nonnegativity constraints: 2.
