Transportation Planning for Medical Products in Hospital, A Case Study of Large Public Hospital in Thailand
Keywords:Vehicle Routing, Transportation, Nearest-Neighbor Heuristic, Linear-Programming
The objective of this research was to plan the transportation route of medical supplies in a case study hospital to minimize overall distances and costs by creating Mathematical Model containing “Linear-Programming” and applying such methodology to calculate the aforementioned route. The shortest route and product quantity were aligned with vehicle’s capacity to solve the ongoing problems; an over-demand upon doctor instruction from each department which subsequently affected hospital maids’ total manpower, a higher number of partial delivery and a highly unplanned labor cost. After applying the designed methodology, the results showed a reduction in distance needed for a weekly delivery from 37,500 meters to 9,500 meters, a total of 28,000 meters or 75 % distance reduction. At the same time, on-time shipments were boosted up from 40 to 95 %. In addition, after assigned a central delivery operating unit with the vehicle capacity of 640,000 cubic centimeters and the designed route calculated from this research, the total operation cost was reduced from 779,060 to 173,120 THB, a total of 605,940 THB or 78 % reduction per month illustrating that the transportation planning for medical products in hospital was proved efficient in the case study hospital.
