Accelerated bender’s decomposition algorithm and hybrid heuristics for multi-period planning of maternal healthcare facilities in India by Ankit Chouksey (20356874)

“…The problem is formulated as a mixed-integer linear programming model to minimize the overall cost, including the cost of establishing and upgrading the facilities, the cost of allocating/referring the mothers-to-be to the respective facilities and the penalty cost of demotivating the overburdening of the facilities in each time period. …”

A model for container stowage planning considering stability constraints by Jingwen Wu (80821)

“…This study addresses the container stowage planning problem for near-sea routes, incorporating stability constraints, container types, and technical limitations related to stack weight and stress. We propose a mixed integer linear programming model to describe this problem and generate load plans that minimize total costs associated with re-stowing and bending moments (BM). …”

Maintenance scheduling optimisation for sustainable steel ladle fleet operations by Victor Ruela (22397830)

“…To address this gap, we present a novel mixed-integer quadratically constrained programming model that captures the complete ladle life cycle, integrating production and refractory degradation constraints to minimise the <math><msubsup>CO<mrow><mn>2</mn></mrow><mrow></mrow></msubsup></math> emissions. …”

Supplementary information files for "Optimising and evaluating centralised infrastructure transitions: A case study of wastewater treatment plants consolidations in the UK" by Yasmin Jaaron (7050692)

“…</p><p dir="ltr">We formulate the optimisation model as an Uncapacitated Transportation and Facility Location Problem (UNCAP-TFLP) using integer Linear Programming (LP), and solve it through a Nearest Neighbour Search Algorithm (NNS-A) supported by GIS tools to address spatial feasibility and routing.…”

Overnight technician routing and scheduling problem with time windows and balanced workloads: a bi-objective zebra optimization algorithm by Abolfazl Gharaei (21803416)

“…This problem is motivated by a real application in the telecommunications industry in Saskatchewan, Canada. A mixed-integer nonlinear programming (MINLP) model is employed to achieve two key objectives: (1) minimising the total costs associated with technicians and subcontractors, including travel costs, accommodation costs and penalty costs caused by late starts and (2) minimising imbalanced workloads. …”
