Oliva et al. (2020)

Mixed integer linear programming (MILP), two binary variants of WOA

Minimized cost feature and total waiting time

A particle swarm optimizer and a mixed statistical test called

Achieved the smallest number of selected features with the best classification accuracy in a minimum time

Tahir et al. (2020)

Implementing two stages, binary chaotic (BCGA) and WOA

Two stages fitness function and BCGA feature given significant classification accuracy

Evolutionary computing-based optimized patient’s waiting time

BCGA map perform better and find a robust subset as compared to other maps in enhancing the performance of raw WOA

The presented method

Inter Linear Programming and WOA technique

Resolves appointment scheduling and waiting time problems for effective FCFS policy and obtained patients satisfaction

Numerical results indicate that both the FCFS and WOA approaches are strategy optimized

Both the FCFS and the WOA strategies data to gain the most propriety (Fairness) results and patient satisfaction
