on the prevailing opinions of retired vehicles owners , and τ age is the aging chain step in years .
In order to ensure the stocks are initialized in equilibrium , the following equations are used to compute the initial values , assuming four age groups

For other aging steps and number of links in the aging chain , the equations for initial equilibrium conditions become more complicated and are not included in this paper .
