Abstract : Four repair versus replacement policies are compared. The main objective of the study was to compare the current policy of Technical Support Directorate (policy 4) with that of policy 1. This suggestion divides the period from the last replacement to the end of need for this type of equipment into that number of equal periods for which expected cost per year will be less than for any other integer divisor. Usually, this results in replacement at a time near the tangent point (of a straight line through the origin) to the estimated parabolic cumulative cost curve. To implement this suggestion, a method for estimating the required constants has been derived. Two additional policies have been included in this comparison. The policy of appendix F (policy 3) was derived by the authors and is included for comparative purposes. Policy 2 is an improved version (devised by the authors) of policy 1 where the size of the current repair cost is considered, in addition to the computed replacement time of policy 1. Data are actually analyzed to arrive a policy decisions. The data are manufactured, but by a wide variety of representative data generators. Actual field data could be processed in much the same fashion. (Author)
