Applications of some modified open sets in r-neighbourhood spaces with ideals [PDF]

open access: yesE3S Web of Conferences, 2023
The purpose of this paper is to introduce r-a-open sets, r-semi open sets and r-pre open sets in ideal r-neighbourhood space. We also discuss their properties, characterizations and relations with existing notions with suitable examples.

Variable Neighbourhood Search and Mathematical Programming for Just‐in‐Time Job‐Shop Scheduling Problem [PDF]

open access: hybridMathematical Problems in Engineering, 2014
This paper presents a combination of variable neighbourhood search and mathematical programming to minimize the sum of earliness and tardiness penalty costs of all operations for just‐in‐time job‐shop scheduling problem (JITJSSP). Unlike classical E/T scheduling problem with each job having its earliness or tardiness penalty cost, each operation in ...

On Mathematical Modelling of Substitution Elements Diffusion in the Neighbourhood of Welded Joint of Steels

open access: hybridMaterials Science Forum, 2007
This paper deals with new approach of measurement of the concentration profiles, concerning the redistribution of substitution elements in close vicinity of welded joint of two different steels. These concentrations have been measured in three straight lines in a plane perpendicular to the weld interface.

A mathematical programming approach for optimal design of distributed energy systems at the neighbourhood level

open access: greenEnergy, 2012
This paper presents a mixed-integer linear programming (MILP) super-structure model for the optimal design of distributed energy generation systems that satisfy the heating and power demand at the level of a small neighborhood. The objective is the optimal selection of the system components among several candidate technologies (micro combined heat and ...

Some applications of continuous variable neighbourhood search metaheuristic (mathematical modelling)

open access: closed, 2012
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University. In the real world, many problems are continuous in nature. In some cases, finding the global solutions for these problems is di±cult. The reason is that the problem's objective function is non convex, nor concave and even not differentiable.
