How do I include post-warranty maintenance personnel costs in TWO COOL® other than by contract?
Since TWO COOL® sums all costs over the useful life of the equipment, timing of expenditures is not a major driver. Thus enter the time weighted average of warranty and post-warranty maintenance technicians by shift into the “Maintenance Cost” section. For example, if the warranty only covers unscheduled maintenance for 2 years, equipment life is 7 years, and a minimum of 2 technicians are required, use the following formula: UM=(2 techs X (7-2 years))/7years = 1.43 unscheduled maintenance techs If the warranty is 1 year, but the equipment user requires that 1 of his technicians be assigned in addition to the 2 technicians provided under warranty, use the following formula: UM=((1 tech X 2 years)+(2 techs X (7-2 years)))/7 years = 1.71 techs Either formula can be directly entered in cells F144 through K144 of the single column model, depending on the number of shifts to be covered. Q: Are any special considerations needed when creating TWO COOL® models for subsequent use in PRO COOL®?
