I NEED AN ANSWR FOR THIS TO VERIFY

A high-tech product manufacturing companv. Plans to design a new printer model. When It comes to printer design, consider three options: I A1: designioriented design-fordrecvcllng, I A2: design-easv-dlsassemblv, I A3: conventional design without any special care for environmental issues, but with a focus on the long life of the printer. The companv commissioned a team of 5 experts to conduct a multi-criteria analysis, based on 4 criteria: I fixed production cost {fl}, I variable production cost 0'2), I environmental friendliness {f3 ) and I expected product life {f4}. The experts rated the design alternatives on a scale of 1-5 [with an excellent 5], with particular emphasis on environmental issues. The average value {aii, i = 1,2,3 and j = 1,2,3] of the scores for each criterion Is given in the following table. Based on the above data: a. Rank the alternatives In descending order of preference. {5 points) b. Examine the sensitivity of the best choice, according to the average value of the experts, when the value of the second-best choice of the environmental friendliness criterion Is changed by $1096. What do you notice about the stability of the first choice? {10 points} c. What Is the average value of the experts in the environmental criterion of the second best choice that is critical for the sta billtv of the first choice? (5 points} d. What would be the order of preference of the alternatives, lfthe emphasis ofthe experts was on the \"variable production cost\" rather than on the \"environmental issues\"? (5 points)
