Çalışmanın Amacı: Son yıllarda çok titiz ve daha zor beğenen tüketici kitlesiyle karşı karşıya kalan pazarlamacılar, ürettikleri mal hizmetleri pazarlama üretim süreçlerine tüketicileri de katma eğilimi göstermektedirler. Müşterilerinin yaratılmasında payı olan şeylere fazla ilgi duyduklarını, sahiplendiklerini bunlara yüksek değer biçtiklerini düşünmektedirler. Sadece tüketmenin değil, üretmen...

1 PROBLEM DEFINITION Given a collection S of sets over a universe U , a set cover C ⊆ S is a subcollection of the sets whose union is U. The set-cover problem is, given S, to find a minimum-cardinality set cover. In the weighted set-cover problem, for each set s ∈ S a weight w s ≥ 0 is also specified, and the goal is to find a set cover C of minimum total weight s∈C w s. Weighted set cover is a...

in the present paper, measure differential equations involving the distributional henstock-kurzweil integral are investigated. theorems on the existence and structure of the set of solutions are established by using schauder$^prime s$ fixed point theorem and vidossich theorem. two examples of the main results paper are presented. the new results are generalizations of some previous results in t...

Probabilistic hesitant fuzzy set (PHFS) is a fruitful concept that adds to hesitant fuzzy set (HFS) the term of probability which is able to retain more information than the usual HFS. Here, we demonstrate that the existing definitions of PHFS are not still reasonable, and therefore, we first improve the PHFS definition. By endowing the set and algebraic operations with a new re-definition of P...

Definition 0.1. S is a countably infinite set if there exists a 1-1 correspondence between S and N. Exercise 0.2. Prove that the following sets are countably infinite: Q, Zn, Qn, the set of algebraic numbers. Definition 0.3. A set S has the cardinality of continuum if there exists a 1-1 correspondence between S and [0, 1]. Definition 0.4. Let S be a set. The power set of S, denoted 2S , is the ...

let h be an infinite--dimensional hilbert space and k(h) be the set of all compact operators on h. we will adopt spectral theorem for compact self-adjoint operators, to investigate of higher derivation and higher jordan derivation on k(h) associated with the following cauchy-jencen type functional equation 2f(frac{t+s}{2}+r)=f(t)+f(s)+2f(r) for all t,s,rin k(h).

The aim of a multi-mode resource-constrained project scheduling problem (MRCPSP) is to assign resource(s) with the restricted capacity to an execution mode of activities by considering relationship constraints, to achieve pre-determined objective(s). These goals vary with managers or decision makers of any organization who should determine suitable objective(s) considering organization strategi...
