자가격리자 수용 호텔 내 로봇을 활용한 룸서비스 배송 방안 = Operation Plan for Robot Room Service Delivery in a Self-quarantine Hotel

다국어 초록 (Multilingual Abstract)

The purpose of this paper is to propose a room service delivery operation plan using robots in a hotel that accommodates self-quarantine people as guests.
To do this, a mathematical model that turns the robot operation problem into a knapsack problem by reflecting the uniqueness of the hotel’s spacial environment is presented. The experiments are conducted by comparing the proposed mathematical model with various packaging methods for scenarios in which orders can and can’t be canceled in a virtual hotel that accommodates self-quarantine people. A result of the experiment showed that the proposed mathematical model applying the knapsack problem shortens the average exceeding time of the delivery time limit for the self-quarantine guests and increased the number of orders delivered within the time limit in both scenarios when compared to (1) First In First Out method and (2) 2 Items with Exceeded Time Window methods. In addition, it was confirmed that standardized delivery service can be provided to self-quarantine guests compared to (3) Routing Time Minimizing method.
