Advanced: Formulation of initial tableau and interpretation of final tableau Reverse signs in Final tableau.

D Electronics produces three models of satellite dishes-Alpha, Beta and Gamma-which have contributions per unit of £400, £200 and £100 respectively.

There is a two-stage production process and the number of hours per unit for each process are:

There is an upper limit on process hours of 1920 per period for Process 1 and 2200 for Process 2.
The Alpha dish was designed for a low-power satellite which is now fading and the sales manager thinks that sales will be no more than 200 per period.
Fixed costs are £40 000 per period.
You are required to

(a) formulate these data into a Linear Program¬ ming model using the following notation:

(d)investigate the effect on the solution of each of the following:
(i) an increase of 20 hours per period in Process 1, (ii) an increase of 10 units per period in the output of Alpha, (iii) receiving an order, which must be met, for 10 units of Gamma.
