3.49 Selecting a maintenance support system. ARTHUR is the a. How many maintenance organization alternatives exist Norwegian Army\'s high-tech radar system designed to identify and track \"unfriendly\" arillery grenades, calculate where enemy positions are, and direct counterattacks on the enemy. In the Journal of Quality in Maintenance Engineer- ing (Vol. 9, 2003), researchers used an analytic hierarchy process to help build a preferred maintenance organization for ARTHUR. The process requires the builder to select al 3.50 Monitoring impedance to leg movements. Refer to the ternatives in three different stages (called echelons). In the first echeion, the builder must choose one of two mobile when choices are made in the three echelons? b. The researchers determined that only four of the alter- natives in part a are feasible alternatives for ARTHUR. If one of the alternatives is randomly selected, what is the probability that it is a feasible alternative? units (regular soldiers or soldiers with engineering training). In the second echelon, the builder chooses one of three heavy mobile units (units in the Norwegian Army, units from Supplier 2, or shared units). Finally, in the third eche- lon the builder chooses one of three maintenance work IEICE Transactions on Information&Systems; (Jan. 2005) study of impedance to eg movement, Exercise 2.36 (p. 37). Recall that Korean engineers attached electrodes to the ankles and knees of volunteers and measured the voitage readings between pairs of electrodes. These read- ings were used to determine the signal-to-noise ratio (SNR) of impedance changes such as knee flexes and hip shops (Norwegian Army, Supplier1, or Supplier 2).

Solution

3.49)

a) Number of maintainence organisations = 2*3*3 = 18 Answer

b) Probability that it is a feasible alternative = 1/18 * 4/18 = 0.01234 Answer
