In this.paper, we have cons.dered a s.ries.parallel s.s.em to find out optimum s.s.em reliability with an additional entropy objective function. Maximum s.s.em reliability of s.ries.parallel s.s.em is.depending.on proper allocation of redundancy component in different s.ag.. The g.al of entropy bas.d reliability redundancy allocation problem is.to find optimal number of redundancy component in each s.ag. s.ch a manner that maximize the s.s.em reliability s.bject to available total s.s.em cos.. g.obal criterion method is.us.d to analyze entropy bas.d reliability optimization problem with different weig.t function of objective functions. Numerical examples.have been provided to illus.rate the model.

The importance of rapid tooling.(RT) and additive manufacturing.(AM) appears.to be indis.ens.ble for boos.ing.the proces. of manufacturing.and expanding.the horizon of production technolog. worldwide. This.concept draws.the attention of numerous.s.holars.to arrive at a conclus.ve theory for the wides.read utilization of RT. This.s.udy attempts.to determine the viability and performance of an RT electrode in the field of electro dis.harg. machining.(EDM). The electrode prototype is.made us.ng.an acrylonitrile butadiene s.yrene (ABs. plas.ic by fus.d depos.tion modeling.(FDM), an AM technique, electroplated with copper of des.red thicknes., and us.d in die s.nking.EDM of D2 s.eel. The s.anning.electron micros.ope analys.s.of the electroplated s.mples.confirms.that it is.pos.ible to obtain the des.red thicknes. of the metal by electroplating.on any electrically conductive s.rfaces. In the pres.nt work, an experimental s.udy is.performed for examining.the electroplated copper thicknes. of the plas.ic EDM electrode and its.performances. It is.found that the electroplated ABs.plas.ic EDM RT electrode s.cces.fully performs.the machining.operation of D2 s.eel, and the res.lts.are comparable with a s.lid electrode. The s.udy reveals.that the RT electrode can be reg.rded as.a viable tool for roug. cutting.or s.mi-finis.ing.cut EDM functions. The experimental res.lts.are thoroug.ly dis.us.ed, examined, analyzed, and evaluated for the purpos. of developing.the appropriate form of the concept.

The optimal control of nonlinear s.s.ems.has.been s.udied for years.by many res.archers. However, the application of optimal control problem to nonlinear non-affine s.s.ems.needs.more attention. In this.paper we propos. an optimal control des.g. technique for a clas. of nonlinear and control non-affine equations. The dynamic equations.of a flexible s.aft s.pported by a pair of active mag.etic bearing. (AMBs. are us.d as.the nonlinear control non-affine equations. Mathematical model for the flexible beam is.chos.n to be the well known Timos.enko beam model, which takes.rotary inertia and s.ear deformations.into account, and it is.as.umed that the s.aft is.s.pported by two frictionles. bearing. at the ends. The effective control of s.ch s.s.ems.is.extremely important for very hig. ang.lar velocity s.afts.which are a feature of many modern machines. The control mus. be able to cope with unbalanced mas.es.and hence be very robus.. We s.all approach the problem by dis.retis.ng.the Timos.enko beam model and us.ng.s.andard difference formulae to develop a finite-dimens.onal model of the s.s.em. Then we us. a recently developed technique for controlling.nonlinear s.s.ems.by reducing.the problem to a s.quence of linear time-varying.(LTV) s.s.ems. An optimal control des.g.ed for each approximating.linear, time-varying.s.s.em and recent res.lts.s.ow that this.method will converg. uniformly on compact time intervals.to the optimal s.lution.
