Efficient Minimum Flow Decomposition via Integer Linear Programming.

Publication Type: Academic Journal

Source(s): Journal of computational biology : a journal of computational molecular cell biology [J Comput Biol] 2022 Nov; Vol. 29 (11), pp. 1252-1267. Date of Electronic Publication: 2022 Oct 18.

Abstract: Minimum flow decomposition (MFD) is an NP-hard problem asking to decompose a network flow into a minimum set of paths (together with associated weights). Variants of it are powerful models in multiassembly problems in Bioinformatics, such as RNA assemb...

An Integer Linear Programming Approach for Scaffolding Based on Exemplar Breakpoint Distance.

Publication Type: Academic Journal

Source(s): Journal of computational biology : a journal of computational molecular cell biology [J Comput Biol] 2022 Sep; Vol. 29 (9), pp. 961-973. Date of Electronic Publication: 2022 May 19.

Abstract: Reference-based scaffolding is an important process used in genomic sequencing to order and orient the contigs in a draft genome based on a reference genome. In this study, we utilize the concept of genome rearrangement to formulate this process as an ...

Solution to dynamic economic dispatch with prohibited operating zones via MILP.

Publication Type: Academic Journal

Source(s): Mathematical biosciences and engineering : MBE [Math Biosci Eng] 2022 Apr 24; Vol. 19 (7), pp. 6455-6468.

Authors:

Abstract: Dynamic economic dispatch (DED) problem considering prohibited operating zones (POZ), ramp rate constraints, transmission losses and spinning reserve constraints is a complicated non-linear problem which is difficult to solve efficiently. In this paper...

A target-based distributionally robust model for the parallel machine scheduling problem.

Publication Type: Academic Journal

Source(s): International Journal of Production Research. Nov2022, Vol. 60 Issue 22, p6728-6749. 22p. 9 Charts, 3 Graphs.

Abstract: We develop a distributionally robust optimisation (DRO) model based on a risk measure for the parallel machine scheduling problem (PMSP) with random job processing times. We propose an underperformance risk index (URI) to control the extent of the tota...

An evaluation of several combinations of routing and storage location assignment policies for the order batching problem.

Publication Type: Academic Journal

Source(s): International Journal of Production Research. Oct2022, Vol. 60 Issue 19, p5892-5911. 20p. 3 Diagrams, 9 Charts, 4 Graphs.

Abstract: In this work, we address the Order Batching Problem (OBP) and we devise tailor-made Mixed Integer Linear Programming (MILP) formulations of the OBP considering composite, largest gap and optimum routing policies, for the first time. We also introduce a...

A Joint Assembly Line Balancing and Feeding Problem (JALBFP) considering direct and indirect supply strategies.

Publication Type: Academic Journal

Source(s): International Journal of Production Research. Oct2022, Vol. 60 Issue 19, p5727-5745. 19p. 3 Diagrams, 7 Charts, 1 Graph.

Abstract: In an assembly system, balancing the line and designing the part feeding setting play a fundamental role in guaranteeing efficiency and effectiveness. Although these two aspects are interrelated, they are usually performed subsequent to each other, wit...

Performance analysis and optimisation of stochastic flow lines with limited material supply.

Publication Type: Academic Journal

Source(s): International Journal of Production Research. Sep2022, Vol. 60 Issue 17, p5293-5306. 14p. 1 Diagram, 4 Charts, 7 Graphs.

Abstract: We consider stochastic flow lines with limited buffer sizes and limited material supply. In these systems, the configuration of the flow line parameters and the configuration of the material supply determine the system output. Shortages of material sup...

Household-level consumption data can be redistributed for individual-level Optifood diet modeling: analysis from four countries.

Publication Type: Academic Journal

Source(s): Annals of the New York Academy of Sciences [Ann N Y Acad Sci] 2022 Mar; Vol. 1509 (1), pp. 145-160. Date of Electronic Publication: 2021 Nov 30.

Abstract: A barrier to using Optifood linear programming (LP), which identifies nutrient gaps and supports population-specific food-based recommendation (FBR) development, is the requirement for dietary intake data. We investigated whether Household Consumption ...
