Nnene, Obiora A.; Joubert, Johannes Willem; Zuidgeest, Mark H.P. (Elsevier, 2019)This article presents the design and evaluation of transit networks using a route expansion heuristic and agent-based travel demand simulation. The route expansion mechanism is a type of constructive heuristic algorithm ...

Willemse, Elias J.; Joubert, Johannes Willem (Elsevier, 2016-07)In this article we present benchmark datasets for the Mixed Capacitated Arc Routing Problem under Time restrictions with Intermediate Facilities (MCARPTIF). The problem is a generalisation of the Capacitated Arc Routing ...

Joubert, Johannes Willem; De Beer, Dirk Johannes; De Koker, Nico (Elsevier, 2016-08)Telemetry devices are generating and transferring increasingly more data, with notable potential for decision makers. In this paper we consider the accelerometer and speed data produced by in-vehicle data recorders as a ...

Venter, C.J. (Christoffel Jacobus); De Beer, L.R.; Du Preez, Simeon; Joubert, Johannes Willem (South African Institution Of Civil Engineering, 2022-05)Over the last 15 years South Africa has invested heavily in the upgrading of public transport. However, issues such as slow deployment, limited impacts, and financial underperformance of our budding Bus Rapid Transit ...
-
Vosloo, Jaco-Ben; Joubert, Johannes Willem (Operations Research Society of South Africa, 2019)The rapid development and proliferation of global positioning system (GPS)-enabled systems and devices have led to a signi cant increase in the availability of transport data, more speci cally GPS trajectories, that can ...
-
Willemse, Elias J.; Joubert, Johannes Willem (Elsevier, 2019-05)In this paper, we extend our previous work on greedy constructive heuristics for the Mixed Capacitated Arc Routing Problem under Time Restrictions with Intermediate Facilities (MCARPTIF) by developing efficient local search ...
-
Dempers, Clemens A.; Joubert, Johannes Willem (Elsevier, 2019)Recent advances in large-scale mobility models have shown that much system-level insight can be gained when modelling at the disaggregate, individual level. Although the focus is often on the movement of vehicles and/or ...

Becker, Henrik; Becker, Felix; Abe, Ryosuke; Bekhor, Shlomo; Belgiawan, Prawira F.; Compostella, Junia; Frazzoli, Emilio; Fulton, Lewis M.; Bicudo, Davi Guggisberg; Gurumurthy, Krishna Murthy; Hensher, David A.; Joubert, Johannes Willem; Kockelman, Kara M.; Kroger, Lars; Le Vine, Scott; Malik, Jai; Marczuk, Katarzyna; Nasution, Reza Ashari; Rich, Jeppe; Carrone, Andrea Papu; Shen, Danqi; Shiftan, Yoram; Tirachini, Alejandro; Wong, Yale Z.; Zhang, Mengmeng; Bosch, Patrick M.; Axhausen, Kay W. (Elsevier, 2020-08)Automated driving technology along with electric propulsion are widely expected to fundamentally change our transport systems. They may not only allow a more productive use of travel time, but will likely trigger completely ...

Brown, Peter; Joubert, Johannes Willem; Zhou, Yaoqi; RELISH Consortium (Oxford University Press, 2019-10)Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ...

Trent, Nadia M.; Joubert, Johannes Willem; Gidofalvi, Gyozo; Kordnejad, Behzad (Elsevier, 2020)The ubiquity of anonymous GPS data has opened the door to a promising data source in the field of city logistics modelling. From this data the locations of logistics facilities can be extracted and their evolution studied ...
-
Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, Ronald C.W. (Southern African Institute of Mining and Metallurgy, 2015-12)Determining the efficiency of a surface coal mine operation is an essential activity, which can help in deciding on the optimal use of input resources, including effective capital allocation, in generating a desired ...
-
Bean, Willemiena Lodewika; Joubert, Johannes Willem (Elsevier, 2019)There is a need for collaborative urban freight planning and appropriate decision and planning support tools are lacking, resulting in inadequate understanding of how urban freight agents should collaborate and what benefits ...
-
Viljoen, N.M. (Nadia); Joubert, Johannes Willem (Elsevier, 2018-02)This article presents the multilayered complex network formulation for three different supply chain network archetypes on an urban road grid and describes how 500 instances were randomly generated for each archetype. Both ...
-
Hitge, Gerhard; Joubert, Johannes Willem (Elsevier, 2021-01)Establishing cycling as a prominent utility mode is recognised as central to creating sustainable transport systems in many cities around the world. Strategies of starter cycling cities are often biased to the supply of ...
-
Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, Ronald C.W.; Shafiee, Shahriar (Taylor & Francis, 2017)Mining is a competitive business with many players. The survival of a mine in the business is determined by its efficiency and cost-effectiveness relative to the other producers. Both new and operating mines should select ...
-
Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, Ronald C.W. (Southern African Institute of Mining and Metallurgy, 2015-11)Cost estimation for surface coal mines is a critical practice that affects both profitability and competitiveness. New mines require these costs to be estimated using available information before a project begins. ...
-
Viljoen, N.M. (Nadia); Joubert, Johannes Willem (Springer, 2018-03)Making a supply chain more resilient and making it more efficient are often diametrically opposed objectives. Managers have to make informed trade-offs when designing their supply chain networks. There are many methods ...
-
Joubert, Johannes Willem; Kotze, D.J. (Operations Research Society of South Africa, 2020)In production lines, buffers function as a means to decouple stations, which reduce the effect that station failures and varying process times have on the complete line's throughput. However, adding larger buffers can be ...
-
Willemse, Elias J.; Joubert, Johannes Willem (Elsevier, 2016-09)This paper develops optimal and quick near-optimal splitting procedures for the Mixed Capacitated Arc Routing Problem under Time restrictions with Intermediate Facilities. Splitting procedures are a key component of giant ...
