Selecting a good location for an activity or service is fundamentally important. Many different approaches across a range of disciplines have been proposed, developed and explored to address such strategic decision making. With better understanding and insight, as well as better geo-spatial data, a number computational and mathematical advances have been made in recent years. Perhaps the most prominent strategic location problem is attributed to Weber, seeking a point in a continuous space that minimizes the sum of weighted distances to multiple destinations. However, increasingly important is to account for additional concerns, with spatial coverage being equally critical. This paper introduces a bi-objective strategic location problem. A mathematical model formulation is derived and an optimal solution approach is developed. Application findings are reported for a number of case studies.
