Production setup-sequencing and lot-sizing at an animal nutrition plant through ATSP subtour elimination and patching (2010)
Journal Article
Toso, E. A., Clark, A., & Morabito, R. (2010). Production setup-sequencing and lot-sizing at an animal nutrition plant through ATSP subtour elimination and patching. Journal of Scheduling, 13(2), 111-121. https://doi.org/10.1007/s10951-009-0135-7

This paper considers the usefulness of a production lot sizing and scheduling model at an animal nutrition plant with sequence-dependent setup times. The model covers multiple periods and is based on the asymmetric travelling salesman problem (ATSP)....

Lot sizing and sequencing optimisation at an animal-feed plant (2009)
Journal Article
Toso, E. A. V., Morabito, R., & Clark, A. (2009). Lot sizing and sequencing optimisation at an animal-feed plant. Computers and Industrial Engineering, 57(3), 813-821. https://doi.org/10.1016/j.cie.2009.02.011

This paper studies a challenging case of joint lot sizing and scheduling in a manufacturing plant for animal feed compounds. A key characteristic of this industry is that certain products can perform a production line "cleaning" function if a suffici...

Lot sizing and furnace scheduling in small foundries (2008)
Journal Article
Arenales, M. N., de Araujo, S. A., & Clark, A. (2008). Lot sizing and furnace scheduling in small foundries. Computers and Operations Research, 35(3), 916-932. https://doi.org/10.1016/j.cor.2006.05.010

A lot sizing and scheduling problem prevalent in small market-driven foundries is studied. There are two related decision levels: (1) the furnace scheduling of metal alloy production, and (2) moulding machine planning which specifies the type and siz...

Pre-processing optimisation applied to the classical integer programming model for statistical disclosure control (2008)
Presentation / Conference Contribution
Staggemeier, A., Serpell, M., Clark, A., & Smith, J. (2008). Pre-processing optimisation applied to the classical integer programming model for statistical disclosure control. . https://doi.org/10.1007/978-3-540-87471-3_3

A pre-processing optimisation is proposed that can be applied to the integer and mixed integer linear programming models that are used to solve the cell suppression problem in statistical disclosure control. In this paper we report our initial findin... Read More about Pre-processing optimisation applied to the classical integer programming model for statistical disclosure control.

Joint rolling-horizon scheduling of materials processing and lot-sizing with sequence-dependent setups (2007)
Journal Article
De Araujo, S. A., Arenales, M. N., & Clark, A. (2007). Joint rolling-horizon scheduling of materials processing and lot-sizing with sequence-dependent setups. Journal of Heuristics, 13(4), 337-358. https://doi.org/10.1007/s10732-007-9011-9

A lot sizing and scheduling problem from a foundry is considered in which key materials are produced and then transformed into many products on a single machine. A mixed integer programming (MIP) model is developed, taking into account sequence-depen...

Rolling horizon heuristics for production planning and set-up scheduling with backlogs and error-prone demand forecasts (2005)
Journal Article
Clark, A. (2005). Rolling horizon heuristics for production planning and set-up scheduling with backlogs and error-prone demand forecasts. Production Planning and Control, 16(1), 81-97. https://doi.org/10.1080/09537280412331286565

Three families of models and fast heuristic methods are developed for identifying a production plan and immediate set-up schedule for a manufacturing line with changeover times. The initial model is exact, but is optimally solvable only for very shor...

Hybrid heuristics for planning lot setups and sizes (2003)
Journal Article
Clark, A. (2003). Hybrid heuristics for planning lot setups and sizes. Computers and Industrial Engineering, 45(4), 545-562. https://doi.org/10.1016/S0360-8352%2803%2900073-1

The planning of a canning line at a drinks manufacturer is discussed and formulated as a mathematical programming model. Several alternative heuristic solution methods are developed, tested and compared on real data, illustrating the trade-offs betwe...
