Before these costs can be defined, models for distributing modification factors for determining the expected times of the modifications during the warranty period, and for computing the expected MTBF over the warranty period must be developed.
Each change proposal is designed to improve the current MTBF by a factor of M.
Furthermore, the value of each M is dependent upon [theta]*, the specified MTBF the contractor must try to reach with each modification, and upon [theta], the current MTBF of the population of items procured.
Let the initial MTBF be 50 hours, the specified MTBF be [theta]* = 111 hours, M' = 4 and M* = 1.
new] to become greater than or equal to the specified MTBF of 111 hours.
The average MTBF of the software system over the warranty period represents another important measure.
Thus an estimate for the average MTBF is defined in equation 7,
A study by Mercurio and Skaggs (1973) utilized multiple regression analysis to obtain the cost of reliability improvement in terms of the resultant MTBF and the quantity of parts in the item modified.
the average MTBF over the contract defined by equation 7.
Florence Kuteesa, and Tawfik Ramtoolah, both technical assistance advisors in the IMF s Fiscal Affairs Department and AFRITAC East, indicated that they would continue to engage with the participants in the design of the suggested complementary courses, notably in the following areas: construction of baseline for the MTBF, macro-fiscal framework, program based budgeting including monitoring and evaluation.
Vitaliy Kramarenko, AFRITAC South Coordinator said that the seminar presented a unique opportunity to engage officials from the AFRITAC South member countries in the peer-to-peer exchange of ideas on how to make the MTBF more successful in achieving better outcomes in terms of economic growth, infrastructure development, and poverty reduction.
