E-mal: smarand@unm.edu Abstract n ths chapter, Taylor seres s used to solve neutrosophc multobjectve programmng problem (NMOPP). n the proposed approach, the truth membershp, ndetermnacy membershp, falsty membershp functons assocated wth each objectve of multobjectve programmng problems are transformed nto a sngle objectve lnear programmng problem by usng a frst order Taylor polynomal seres. Fnally, to llustrate the effcency of the proposed method, a numercal eperment for suppler selecton s gven as an applcaton of Taylor seres method for solvng neutrosophc mult-objectve programmng problem. Keywords Taylor seres; Neutrosophc optmzaton; Mult-objectve programmng problem. 1 ntroducton n 1995, Smarandache [13], startng from phlosophy (when [8] fretted to dstngush between absolute truth and relatve truth or between absolute falsehood and relatve falsehood n logcs, and respectvely between absolute membershp and relatve membershp or absolute non-membershp and relatve non-membershp n set theory) [12], began to use the non-standard analyss. Also, nspred from the sport games (wnnng, defeatng, or te scores), from votes (pro, contra, null/black votes), from postve/negatve/zero numbers, from yes/no/na, 77
2 Edtors: Prof. Florentn Smarandache Dr. Mohamed Abdel-Basset Dr. Yongquan Zhou from decson makng and control theory (makng a decson, not makng one, or hestatng), from accepted/rejected/pendng, etc., and guded by the fact that the law of ecluded mddle dd not work any longer n the modern logcs [12], Smarandache combned the non-standard analyss wth a tr-component logc/set/probablty theory and wth phlosophy. How to deal wth all of them at once, s t possble to unfy them? [12]. Netrosophc theory means Neutrosophy appled n many felds n order to solve problems related to ndetermnacy. Neutrosophy s a new branch of phlosophy that studes the orgn, nature, and scope of neutraltes, as well as ther nteractons wth dfferent deatonal spectra. Ths theory consders every entty <A> together wth ts opposte or negaton <anta> and wth ther spectrum of neutraltes <neuta> n between them (.e. enttes supportng nether <A> nor<anta>). The <neuta> and <anta> deas together are referred to as <nona>. Neutrosophy s a generalzaton of Hegel's dalectcs (the last one s based on <A> and <anta> only). Accordng to ths theory every entty <A> tends to be neutralzed and balanced by <anta> and <nona> enttes - as a state of equlbrum. n a classcal way <A>, <neuta>, <anta> are dsjont two by two. But, snce n many cases the borders between notons are vague, mprecse, Sortes, t s possble that <A>, <neuta>, <anta> (and <nona> of course) have common parts two by two, or even all three of them as well. Hence, n one hand, the Neutrosophc Theory s based on the trad <A>, <neuta>, and <anta>. n the other hand, Neutrosophc Theory studes the ndetermnacy, labeled as, wth n = for n 1, and m + n = (m+n), n neutrosophc structures developed n algebra, geometry, topology etc. The most developed felds of Netrosophc theory are Neutrosophc Set, Neutrosophc ogc, Neutrosophc Probablty, and Neutrosophc Statstcs - that started n 1995, and recently Neutrosophc Precalculus and Neutrosophc Calculus, together wth ther applcatons n practce. Neutrosophc Set and Neutrosophc ogc are generalzatons of the fuzzy set and respectvely fuzzy logc (especally of ntutonstc fuzzy set and respectvely ntutonstc fuzzy logc). n neutrosophc logc a proposton has a degree of truth (T), a degree of ndetermnacy (), and a degree of falsty (F), where T,, F are standard or nonstandard subsets of ] - 0, 1 + [. Mult-objectve lnear programmng problem (MOPP) a promnent tool for solvng many real decson-makng problems lke game theory, nventory problems, agrculture based management systems, fnancal and corporate plannng, producton plannng, marketng and meda selecton, unversty plannng and student admsson, health care and hosptal plannng, ar force mantenance unts, bank branches etc. 78
3 Neutrosophc Operatonal Research Volume Our objectve n ths chapter s to propose an algorthm to the soluton of neutrosophc mult-objectve programmng problem (NMOPP) wth the help of the frst order Taylor s theorem. Thus, neutrosophc mult-objectve lnear programmng problem s reduced to an equvalent mult-objectve lnear programmng problem. An algorthm s proposed to determne a global optmum to the problem n a fnte number of steps. The feasble regon s a bounded set. n the proposed approach, we have attempted to reduce computatonal complety n the soluton of (NMOPP). The proposed algorthm s appled to suppler selecton problem. The rest of ths chapter s organzed as follows. Secton 2 gves bref some prelmnares. Secton 3 descrbes the formaton of the problem. Secton 4 presents the mplementaton and valdaton of the algorthm wth practcal applcaton. Fnally, secton 6 presents the concluson and proposals for future work. 2 Some prelmnares Defnton 1. [1] A trangular fuzzy number J s a contnuous fuzzy subset from the real lne R whose trangular membershp functon J s defned by a contnuous mappng from R to the closed nterval [0,1], where (6) J 0 for all J, a J 1, (7) J s strctly ncreasng on J a m J (8) J 1 for J m, J 1,, (9) J s strctly decreasng on J m, a J (10) J 0 for all J Ths wll be elcted by: J a 2,. 2, J J J a1, a1 J m, m a 1 a2 J J, m J a2, a2 m 0, otherwse.

For supplyng a new product to a market assume that three supplers should be managed. The purchasng crtera are net prce, qualty and servce. The capacty constrants of supplers are also consdered. t s assumed that the nput data from supplers performance on these crtera are not known precsely.

When they depend on three scalar parameters (a1, m, a2). z 1 depends on neutrosophc aspraton levels (3550,4225,4900), when z 2 depends on neutrosophc aspraton levels (660,681.5,702.5), and z3 depends on neutrosophc aspraton levels (657.5,678.75,700). The truth membershp functons of the goals are obtaned as follows: 0, f z1 3550, 4225 z1, f 3550 z1 4225, z z1, f 4225 z1 4900, , f z , f z , z , f z , z 2 z 2 660, f 660 z , , f z

The problem s solved and the optmal soluton for the truth membershp model s obtaned s as follows: ( 1, 2, 3 ) = (350, 0,450) z 1 =3550, z 2 =662. 5, z 3 = The truth membershp values are 1 1, , The truth membershp functon values show that both goals z 1, z 3 and z 2 are satsfed wth 100%, 11.63% and 89.4% respectvely for the obtaned soluton whch s 1=350; 2= 0, 3=450. n the smlar way, we get X, q(). Consequently, we get the optmal soluton for the ndetermnacy membershp model s obtaned s as follows: ( 1, 2, 3 )=(350,0,450) z 1 =3550, z 2 =662.5, z 3 =697.5 and the ndetermnacy membershp values are 1 1, , The ndetermnacy membershp functon values show that both goals z 1, z 3 and z 2 are satsfed wth 100%, 11.63% and 89.4% respectvely for the obtaned soluton whch s 1=350; 2= 0, 3=450. n the smlar way, we get X and h() Consequently, we get the optmal soluton for the falsty membershp model s obtaned s as follows: ( 1, 2, 3 )=(350,0,450) z 1 =3550, z 2 =662.5, z 3 =697.5 and the falsty membershp values are 1 0, , The falsty membershp functon values show that both goals z 1, z 3 and z 2 are satsfed wth 0%, 88.37% and 10.6% respectvely for the obtaned soluton whch s 1=350; 2= 0, 3= Conclusons and Future Work n ths chapter, we have proposed a soluton to Neutrosophc Multobjectve Programmng Problem (NMOPP). The truth membershp, ndetermnacy membershp, falsty membershp functons assocated wth each objectve of the problem are transformed by usng the frst order Taylor polynomal seres. The neutrosophc mult-objectve programmng problem s 88
13 Neutrosophc Operatonal Research Volume reduced to an equvalent multobjectve programmng problem by the proposed method. The soluton obtaned from ths method s very near to the soluton of MOPP. Hence ths method gves a more accurate soluton as compared wth other methods. Therefore, the complety n solvng NMOPP has reduced to easy computaton. n the future studes, the proposed algorthm can be solved by metaheurstc algorthms.
