Necessary Optimality Conditions for Non-smooth Continuous-Time Problems Using Convexificators
Volume 5, Issue 1 , January 2020, Pages 1-13
Abstract
In this paper, we develop general necessary optimality conditions of the KKT types for non-smooth continuous-time optimization problems with inequality constraints. The primary instrument in our study is the concept of a convexificator. Based on this concept, non-smooth ...

Volume 5, Issue 1 , January 2020, Pages 15-28
Abstract
Linear programming problems have exact parameters. In most real-world, we are dealing with situations in which accurate data and complete information are not available. Uncertainty approaches such as fuzzy and random can be used to deal with uncertainties in real-life. ... Read MoreA Fuzzy Distance Measure for Fuzzy Numbers
Volume 5, Issue 1 , January 2020, Pages 29-39
Abstract
A fuzzy distance measure is introduced in this paper to evaluate the fuzzy distance between two fuzzy numbers. For this purpose, alpha-values of fuzzy numbers are used to develop an integral-based fuzzy distance measure. The properties of the proposed fuzzy distance measure ... Read MoreModeling and Solving a Multi-objective Location-Routing Problem Considering the Evacuation of Casualties and Homeless People and Fuzzy Paths in Relief Logistics
Volume 5, Issue 1 , January 2020, Pages 41-65
Abstract
The relief logistics and humanitarian supply chain in academic literature refer to the process of planning, execution, and effective controlling of the flow of costs and information and storage of necessary goods and materials from the point of origin to consumption with the primary ... Read MoreNumerical Solution of Vasicek Equation by Using Brownian Wavelets and Multiple Ito-Integral
Volume 5, Issue 1 , January 2020, Pages 67-80
Abstract
In this paper, we present a new approach to solving stochastic differential equations and the Vasicek equation by using Brownian wavelets and multiple Ito-integral. Firstly, the calculation of the multiple Ito-integral based on the structure of Brownian motion is presented ...
