Outpatient Appointment Optimization: A Case Study of a Chemotherapy Service

open access: yesApplied Sciences, 2022
In this paper, we study a complex outpatient planning problem in the chemotherapy department. The planning concerns sequences of patients’ treatment sessions subject to exact in-between resting periods (i.e., exact time-lags). The planning is constrained

Optimising a nonlinear utility function in multi-objective integer programming [PDF]

open access: yes, 2012
In this paper we develop an algorithm to optimise a nonlinear utility function of multiple objectives over the integer efficient set. Our approach is based on identifying and updating bounds on the individual objectives as well as the optimal utility ...

A novel clustering method for breaking down the symmetric multiple traveling salesman problem

open access: yesJournal of Industrial Engineering and Management, 2021
Purpose: This study proposes a new two-stage clustering method to break down the symmetric multiple traveling salesman problem (mTSP) into several single standard traveling salesman problems, each of which can then be solved separately using a heuristic ...
