Meso-parametric value function approximation for dynamic customer acceptances in delivery routing

European Journal of Operational Research, 2020
The rise of mobile communication, ample computing power, and Amazon’s training of customers has led to last-mile delivery challenges and created struggles for companies seeking to budget their limited delivery resources efficiently to generate enough ...

Functional Many-Valued Relations

Mathematica Slovaca, 2015
Abstract Many-valued binary relations are considered, taking values in a complete lattice, possibly equipped with additional operations that characterize extended-order algebras. The functionality of such relations is defined, by means of properties such as univocality and totality, from three different perspectives, namely from the ...

Multi-criteria sustainable supplier selection using piecewise linear value function and fuzzy best-worst method

Journal of Intelligent & Fuzzy Systems, 2019
Substantial improvements are being every day made in decisions quality by introducing new Multi Criteria Decision Making (MCDM) methods. Due to the ambiguity in decision data, obtaining the real value of the criteria for modeling multi criteria decision ...

Uncertain Value Functions

Management Science, 1972
Value theory plays an essential role in the formal solution of decision problems, but the experimental determination of value functions is subject to errors of various kinds. Sensitivity analyses are methodologically invalid. An attempt is made to overcome the uncertainties in derivation of value functions, in a manner which is similar to the ...

Semismooth Matrix-Valued Functions

Mathematics of Operations Research, 2002
Matrix-valued functions play an important role in the development of algorithms for semidefinite programming problems. This paper studies generalized differential properties of such functions related to nonsmooth-smoothing Newton methods. The first part of this paper discusses basic properties such as the generalized derivative, Rademacher's theorem ...

Measurable Multiattribute Value Functions

Operations Research, 1979
This paper presents a theory of measurable multiattribute value functions. Measurable value functions are based on the concept of a “preference difference” between alternatives and provide an interval scale of measurement for preferences under certainty.

k-Valued Wilson functions

Aequationes mathematicae, 2021
This is a very interesting and well written paper. Several ideas and concepts are presented explicitly, although not all, so that the paper can be read by mathematicians working in functional equations. Many results concerning the Wilson functional equation on semigroups (including the so-called quadratic functional equation) are presented. It would be

Value function approximation for dynamic multi-period vehicle routing

European Journal of Operational Research, 2018
In practical applications like parcel or technician services, customers request service during the day. Service providers decide whether to accept a customer for same-day service or to defer a customer due to resource limitations.
