Wathsala’s research, “Scheduling Arrivals into a System that Accepts Random Arrivals “, focuses on a general system that accepts both scheduled customers and random customers while the system is open non-pre-emptive priority to scheduled customers. Her main objectives are minimising costs, including total scheduled customers’ waiting for cost, total random customers’ waiting for cost and server idle cost, and maximising the system’s revenue. This problem is a multi-variable multi-objective unconstrained optimisation problem. Several techniques are used for solving the optimisation problem, such as interior-point methods and Pareto optimality, and she compares the optimal solutions. She also compares different models by changing the objective function. This research aims to provide an analytical view of systems that accepts customers who arrive by appointments and randomly. OPTIMA CI Prof. Peter Taylor supervises her.
