Consider an aircraft maintenance station over a planning horizon of n periods. Let Cj be the available labor hours at period j, Aij be the number of aircraft of type i arriving for maintenance at period j, and Pi be the number of labor hours required to perform maintenance on aircraft type i. a) To determine the number of aircraft type i processed at period j, formulate the problem as a linear program.
b) Revise the model so that aircraft would not be delayed for too long.

Based on the supply and demand theory, why do medical doctors earn higher wages than child-care workers?

David consumes two things: gasoline (g) and bread (b). david's utility function is u(g, b) = 10g^0.25 b^0.75. use the lagrange technique to solve for david's optimal choices of gasoline and bread as a function of the price of gasoline, p_g, the price of bread, p_b, and his income m. with recent decrease in the price of gasoline (maybe due to external shock such as shale gas production) does david increase his consumption of gasoline? for david, how does partial differential g/partial differential p_g depend on his income m? that is, how does david's change in gasoline consumption due to an increase in the price of gasoline depend on his income level? to answer these questions, find the cross-partial derivative, |partial differential^2 g/partial differential m partial differential p_g.
