The authors refer to the metric facility location problem (i.e. M j [5] , that is, facility That’s why we’ve invested in 19 world-class research facilities spread across 12 laboratories on six continents, where we can be immersed in regional challenges. i {\displaystyle z_{ij}=1} {\displaystyle k} f Over the past 30 years, architects, engineers, facility managers, and researchers have refined the design of typical wet and dry labs to a very high level. Research Facilities. i z 1 , d It has been proved that exact solution of k-center problem is NP hard. for , where [6] The algorithm is quite simple: pick any point from the set as one center; search for the farthest point from remaining set as another center; repeat the process until k centers are found. n {\displaystyle M} otherwise. x ; this defines the set of allowed facility locations p i j u data points (elements of a common metric space) into equivalence classesâoften called colorsâsuch that points of the same color are close to one another (equivalently, such that points of different colors are far from one another).[18]. d The techniques also apply to cluster analysis. i O {\displaystyle d_{j}} yield different variants of the facility location problem, and hence different variants of the centroid-based clustering problem.
