A relax-and-fix method for clothes inventory balancing scheduling problem.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. Oct2023, Vol. 61 Issue 20, p7085-7104. 20p. 2 Diagrams, 13 Charts, 1 Graph.
Abstract: The clothes inventory balancing scheduling problem (CIBSP) among branch stores with the allowance of lateral transshipments has gained increasing attentions in fast-fashion apparel industry, especially for the trial sale of new products. To solve the C...
A stochastic dual dynamic integer programming based approach for remanufacturing planning under uncertainty.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. Sep2023, Vol. 61 Issue 17, p5992-6012. 21p. 5 Charts, 2 Graphs.
Abstract: We seek to optimize the production planning of a three-echelon remanufacturing system under uncertain input data. We consider a multi-stage stochastic integer programming approach and use scenario trees to represent the uncertain information structure....
The multi-manned joint assembly line balancing and feeding problem.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. Aug2023, Vol. 61 Issue 16, p5543-5565. 23p. 5 Diagrams, 6 Charts, 3 Graphs.
Abstract: The Joint Assembly Line Balancing and Feeding Problem (JALBFP) assigns a line feeding mode to each component (Assembly Line Feeding Problem) and each task to a workplace of a station (Assembly Line Balancing Problem). Current literature offers numerous...
The discrete time break scheduling problem under fatigue and no preemption: solution methods and impact of work regulations.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. Aug2023, Vol. 61 Issue 16, p5372-5391. 20p. 7 Charts, 5 Graphs.
Abstract: We address the discrete time break scheduling problem with no preemption when workers' fatigue impacts their productivity. We propose a Mixed Integer Linear Programming model to solve the one break problem to optimality, using a lexicographic approach ...

Abstract: This note comments on the study of [Diri Kenger, Zülal, Çağrı Koç, and Eren Özceylan. 2020. "Integrated Disassembly Line Balancing and Routing Problem." International Journal of Production Research 58 (23): 7250–7268.] which studies an integrated disas...
An integrative decision-making model for the Internet of Things-enabled supply chains of fresh agri-product.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. Jul2023, Vol. 61 Issue 13, p4358-4373. 16p. 2 Diagrams, 8 Charts, 5 Graphs.
Abstract: The application of new information technologies such as the Internet of Things (IoT) has caused a deep impact on production and operations management in various fields. In this paper, a mixed-integer programming model is proposed to generate integrativ...
Network-based integer programming models for flexible process planning.
Publication Type: Academic Journal
Source(s): International Journal of Production Research. May2023, Vol. 61 Issue 9, p3087-3101. 15p. 3 Diagrams, 13 Charts.
Abstract: Flexible process planning (FPP) involves selecting and sequencing the requisite operations according to technological requirements, and meanwhile allocating a right machine, a right tool and a right access direction to each selected operation by a give...
A new generalization of edge-irregular evaluations.
Publication Type: Academic Journal
Source(s): AIMS Mathematics (2473-6988). 2023, Vol. 8 Issue 10, p25249-25261. 13p.
Abstract: Consider a simple graph G = (V, E) of size m with the vertex set V and the edge set E. A modular edge-irregular total k-labeling of a graph G is a labeling scheme for the vertices and edges with the labels 1, 2, . . ., k that allows the modular weights...
On Parametric and Matrix Solutions to the Diophantine Equation x2+dy2−z2=0 Where d Is a Positive Square‐Free Integer.
Publication Type: Academic Journal
Source(s): International Journal of Mathematics & Mathematical Sciences. 9/25/2023, p1-18. 18p.
Abstract: The well‐known matrix‐generated tree structure for Pythagorean triplets is extended to the primitive solutions of the Diophantine equation x 2 + d y 2 − z 2 = 0 where d is a positive square‐free integer. The proof is based on a parametrization of these...
An upper bound on triple Roman domination.
Publication Type: Academic Journal
Source(s): Communications in Combinatorics & Optimization. 2023, Vol. 8 Issue 3, p505-511. 7p.
Abstract: For a graph G=(V,E), a triple Roman dominating function (3RD-function) is a function f:V→{0,1,2,3,4} having the property that (i) if f(v)=0 then v must have either one neighbor u with f(u)=4, or two neighbors u,w with f(u)+f(w)≥5 or three neighbors u,w...
