| Summary: | Choosing the suitable site for a new hospital is a difficult aspect of decision-making for the
decision-makers. Large data availability with challenging features and the proliferation of
different methodologies have made it extremely difficult to select the best models that
perform for a particular site selection problem. This research provided a comprehensive
study for hospital site suitability and introduced machine learning models. The experiment
was conducted in two study areas which are Gaza Strip, Palestine and Melaka, Malaysia.
First, the conditioning factors were optimized and ranked to identify and select the most
correlated factors to predict the suitability of a hospital site by applying the correlation
feature selection (CFS) algorithm and the greedy-stepwise search method. Second, to
assess the hospital site suitability, three machine learning (ML) models, namely, support
vector machine (SVM), multilayer perceptron (MLP) and linear regression (LR) were
introduced to predict the suitability of the hospital site. In addition, two multi-criteria
decision-making models (MCDM), namely, analytical hierarchy process (AHP) and fuzzy
overlay were used to compare the models and verify the results. The ML models
Performance were verified using the receiver operating characteristics (ROC) curves and
cross-validation with other evaluation metrics; correlation coefficient, root mean square
error (RMSE), mean absolute error (MAE), relative absolute error (RAE), as well as root
relative squared error (RRSE). The comparison of the model shows that in Melaka and
Gaza Strip, MLP (AUC: 92.20%, 84.90%) and AHP (AUC: 91.40% and 83.20%) are more
reliable and acceptable for hospital suitability mapping in both locations with consistent
and realistic results. The high-level performance and accuracy of the model outcomes
supported the conclusion that the proposed methodology in this research can successfully
produce a site suitability map for locating new hospitals. Third, an insight into the machine
learning models utilized and how their predicted weights affect hospital site suitability
mapping was provided. A clear dissimilarity between the ML and MCDM models in terms
of the predicted weights characteristics of the conditioning factors in both study areas are
discovered. The study has revealed that some conditioning factors are more significant than
others because of inherent traits associated with the spatial characteristics of each case
study that results in the differences in the weights. Fourth, five location-allocation models
were implemented based on the calculus of coverage, mainly implemented in the search
for poor coverage to propose new hospital sites in both study areas. In this research, site
suitability from one study area to another was verified using all the implemented methods.
Thus, the proposed approaches would be effectively and easily replicated in other regions.
Moreover, the results of the proposed approaches provided detailed information that would
be useful to decision makers to locate the hospital for effective health delivery planning
and implementation. |
