Written in an enticing sort, Replacement types with minimum fix balances advanced mathematical types with useful functions. it truly is divided into six components that cover:
- mathematical modeling of minimum repair;
- preventive upkeep versions and optimum scheduling of imperfect preventive upkeep activities;
- a new guaranty servicing approach with imperfect repair;
- mathematical versions combining burn-in strategy and normal upkeep policies;
- methods for parameters’ estimation of minimum fix versions; and
- product support.

Chien and Chen  consider an age-replacement policy, in which MR or replacement takes place according to the following scheme. If the product fails before age T; it is either replaced by a new product (due to type II failure with probability p) at a downtime cost cd and a purchasing cost cp , or it undergoes MR (due to type I failure with probability 1 À p) at a MR cost cm : Otherwise, the product is preventively replaced whenever it reaches age T: For a repairable product purchased under the renewing free-replacement warranty (RFRW), if a failure occurs within the warranty period w; either a new product with the same warranty is offered, free of charge by the seller, to replace the failed one (type II failure); or a MR is performed free of charge by the seller (type I failure).
The product is sold under warranty and burn-in is required " the Sf of the failure time and before the product is put on sale. -S. Ouali et al. where c0 is the manufacturing cost per unit without burn-in, c1 is the fixed setup cost of burn-in per unit, c2 is the cost per unit time of burn-in per unit, and c3 is the minimal repair cost per type I failure during burn-in. The first warranty policy considered is the failure-free policy in which the manufacturer is responsible for all the repair and replacement costs during the warranty period ½0; T: Two cases are considered under this policy, namely renewing and non-renewing.
In this case, the expected length of life cycle is represented as " E½cycle ¼ IðwÞ þ ðw þ sÞFðwÞ; Rw " are the pdf and Sf of the time to first where IðwÞ ¼ 0 tf ðtÞdt and f ðtÞ and FðtÞ failure of the system, respectively. Denote by qðtÞ the failures rate and let cr be the unit cost of replacement, cm be the unit cost of MR, cfw be the unit failure cost during the warranty period, and cfm be the unit failure cost during the maintenance period. Then, the expected cost rate per unit time for the case of renewing warranty can is R wþs " c0 þ ðcm þ cfm ÞFðwÞ qðtÞdt w ; CðsÞ ¼ " IðwÞ þ ðw þ sÞFðwÞ where & cr c0 ¼ " w IðwÞ þ cfw FðwÞ þ cr FðwÞ; " cfw FðwÞ þ cr FðwÞ; RPRW; RFRW; while the expected downtime per unit time is h i R wþs " dðwÞFðwÞ þ dr þ w dðtÞqðtÞdt FðwÞ ; DðsÞ ¼ " IðwÞ þ ðw þ sÞFðwÞ where dr is the length of downtime due to replacement at the end of the maintenance period and dðwÞ is the downtime function due to MR at time w: 2.
