Graph theory is a very natural and powerful tool in combinatorial research. Some necessary research issues particularly inventory control problem that may be resolved using graphs. It suggests the chances that exist for improving the operational, military science and strategic decision-making of health care inventory systems through the employment of graph theory approaches. This blog aims to boost the attention of health care managers and  inventory researchers with relevance to realistic graph theory applications. Overview Graph theory introduction Graph theory in real world problems  Google maps  Graphs in Healthcare system EHR System Conclusion Graph theory introduction : Graph theory may be a mathematical sub-field of discrete mathematics. In graph theory, we have tendency to study graphs, which might be accustomed to describe pairwise relationships between objects. Graph theory was created in 1736, by the mathematician Leonhard Euler . Graph with
