Title: | Capacity Alignment Planning for a Coal Chain: A Case Study | Contributor(s): | Eskandarzadeh, Saman (author); Kalinowski, Thomas (author) ; Waterer, Hamish (author) | Publication Date: | 2021 | DOI: | 10.1007/978-3-030-60135-5_8 | Handle Link: | https://hdl.handle.net/1959.11/31322 | Abstract: | We study a capacity alignment planning problem for a coal chain. Given a set of train operators, a set of train paths and a terminal comprising of a dump station and a set of routes from the dump station to the stockyard, we seek a feasible assignment of train operators to train paths, to time slots at the dump station, and to routes. The assignment must maximize the number of system paths in the resulting schedule and the schedule should perform well with respect to various performance criteria. We model the problem as a mixed-integer conic program (MICP) with multiple objectives which we solve using a hierarchical optimization procedure. In each stage of this procedure, we solve a single objective MICP. Depending upon whether we evaluate the associated performance criteria under a 2- or 1-norm, we reformulate the MICP as either a mixed-integer second-order cone program or as a mixed-integer linear program, respectively, and can streamline the hierarchical optimization procedure by exploiting properties of the model or observed behaviour on practical instances. We compare the performance of the procedure under the different norms on a real instance of the problem and find that the quality of the solutions found by the faster 1-norm procedure compares well to the solution found under the 2-norm. | Publication Type: | Conference Publication | Conference Details: | ASOR/DORS Conference 2018: 26th Australian Society for Operations Research and Defence Operations Research Symposium 2018, Melbourne, Australia, 4th - 6th December, 2018 | Grant Details: | ARC/LP140101000 | Source of Publication: | Data and Decision Sciences in Action 2: Proceedings of the ASOR/DORS Conference 2018, p. 111-124 | Publisher: | Springer | Place of Publication: | Cham, Switzerland | Fields of Research (FoR) 2008: | 010206 Operations Research | Fields of Research (FoR) 2020: | 490108 Operations research | Socio-Economic Objective (SEO) 2008: | 850702 Energy Conservation and Efficiency in Transport | Socio-Economic Objective (SEO) 2020: | 170104 Transport energy efficiency | Peer Reviewed: | Yes | HERDC Category Description: | E1 Refereed Scholarly Conference Publication | Publisher/associated links: | https://www.confer.nz/asor-dors2018/programme/ | WorldCat record: | http://www.worldcat.org/oclc/1241066298 | Series Name: | Lecture Notes in Management and Industrial Engineering |
