Abstract
Bi-objective Emergency Medical Service Design Problem is a problem to determining the location of the station Emergency Medical Service among all candidate station location, the determination of the number of emergency vehicles allocated to stations being built so as to serve medical demand. This problem is a multi-objective problem that has two objective functions that minimize cost and maximize service. In real case there is often uncertainty in the model such as the number of demand. To deal the uncertainty on the bi-objective emergency medical service problem is using Robust Optimization which gave optimal solution even in the worst case. Model Bi-objective Emergency Medical Service Design Problem is formulated using Mixed Integer Programming. In this research, Robust Optimization is formulated for Bi-objective Emergency Medical Service Design Problem through Robust Counterpart formulation by assuming uncertainty in demand is box uncertainty and ellipsoidal uncertainty set. We show that in the case of bi-objective optimization problem, the robust counterpart remains computationally tractable. The example is performed using Lexicographic Method and Branch and Bound Method to obtain optimal solution.
Highlights
According to Zhang and Jiang [1] emergency health services are designed to provide health care to people who need medical assistance quickly and effectively
The following notation is used in bi-objective emergency medical service design problem model
In bi-objective emergency medical service design problem according to [1] has the demand parameter, where the demand parameter is uncertain
Summary
According to Zhang and Jiang [1] emergency health services are designed to provide health care to people who need medical assistance quickly and effectively. It is hard to be predicted what will happen, maybe in a region can occur disasters, epidemics, accidents or other events that require handling health. This causes emergency health service facilities to be one of the most important public facilities in handling health. Emergency health service facilities provide services to emergency medical requests. To be able to provide maximum service, the location of construction of facilities must be considered to reach points of the request. It is essential to determine the location of the construction of emergency health service facilities
