비즈니스호텔의 최적 입지 결정에 관한 연구

송병덕,고영대 한국관광학회 2016 관광학연구 Vol.40 No.9

시설 입지 선정 문제는 1960년대부터 수리적 모형의 개발을 통해 광범위하게 다루어져 왔었다. 하지만, 호텔 산업에서의 경영과학 관점의 접근을 통한 호텔의 최적 입지 선정은 매우 제한적으로 다루어졌다. 본 연구에서는 제한된 예산 하에서 새로운 비즈니스호텔의 최적 입지와 객실 수를 결정하기 위한 수리적 모형을 개발하였으며, 해법 방법론으로써는 유전 알고리즘을 개발하였다. 제안된 수리 모형과 유전 알고리즘은 서울특별시 내에 위치한 실제 대기업 본사 위치 데이터와 임의의 호텔 데이터를 이용하여 실험하였으며, 최적의 호텔 입지와 객실 수를 짧은 시간 안에 도출해 냄으로써 그 타당성을 검증하였다. The Facility location challenge has been widely addressed by using various mathematical models since 1960s. However, there are not sufficient Operation Research perspective approaches on the location problems throughout the hotel industry. In this study, we developed a mathematical model to optimize the location and size of new business hotels within their budget restrictions. As a solution approach, a genetic algorithm was developed. A proposed mathematical model and a genetic algorithm were tested using the real data of head offices and using hypothesis hotels data in Seoul metropolitan city. A Proposed mathematical model and a genetic algorithm were examined via numerical example by deriving the optimal location and size of new hotels in a reasonable time.

Capacitated Location and Allocation Models of Long-Term Care Facilities

송병덕,고영대,제임스모리슨,황학 대한산업공학회 2013 Industrial Engineeering & Management Systems Vol.12 No.3

People are living longer than ever before. As a result, life expectancy is going up and the demand of long-term care facilities is increasing in most countries. The facilities provide rehabilitative, restorative, and skilled nursing care to patients or residents in need of assistance with activities of daily living. This study deals with the capacitated location and allocation problem of long-term care facilities in a city that consists of a finite number of regions. Assuming that in each region candidate locations for three types of facilities are already given, two integer programming models are developed under the closest assignment rule reflecting the demand characteristics of the facilities. Both the location and type of the facilities to be built become decision variables. To show the validity of the models, numerical prob-lems are solved with commercial software, CPLEX. Also, sensitivity studies were conducted to identify relationships between the system parameters.

Microstructure of polycrystalline Lead Telluride was controlled by the change of sintering conditions. Three properties which determine the thermoelectric figure of merit of the material were measured in the temperature range of 300-650K in order to investigate the effect of each sintering condition on the thermoelectric efficiency. Based on the observed experimental results, defect structure is concluded to be more important than microstructure though both can be controlled by processing variables.

There are Various traditional arts in korea. However, the wrestling Peculiar to korea gives an impression like a national sport. The objects of the korean wrestling are to Promote mutual friendship and to improve physical conditions. And it has been played as a healthy sport of a recreation. They held the Wrestling Contest in most parts of the country on the Dan-O(the 5th day of the fifth lunar month) of on Chu-Seok (the 15th of August by the lunar Calender) to cultivate courageous mental Power and to harden the body . A thousand of People gathered together from various parts of the Country when they held the wrestling contest. And the wrestling of the younger generation has been Prosperous in that way in korea.

With legislations and customers’increased attention to environment issues, interests on reverse logistics have been increased. In this paper, we address a design issue of reverse logistics network with the objectives of minimizing total establishment cost of collection centers and transportation cost of collected end-of-used product by determining the locations of centers, reverse logistics network and minimum quality of end-of-used product to be collected. We propose mathematical model and genetic algorithm to support such decisions. Validity of the proposed genetic algorithm was tested via numerical experiments with various distributions on the quality of end-of-products.

공급 사슬 확장을 위한 네트워크 재설계에 관한 연구

송병덕(Byung Duk Song),오용희(Yonghui Oh) 한국전자거래학회 2012 한국전자거래학회지 Vol.17 No.4

시장 상황의 변화에 따라 상품의 효율적인 공급을 위해 기업은 한정된 예산 내에서 공급사슬을 변화시킬 필요가 있다. 또한, 경쟁의 심화로 공급 사슬 내에서의 비용절감뿐만 아니라 적절한 공급 사슬의 구성을 통해 상푸의 정시 배송 등 고객 만족도를 높이는 것은 점점 더 중요한 요소로 고려되고 있는 추세이다. 본 연구에서는 공급 사슬 확장에 따른 네트워크 재설계 문제를 다루고 있으며 이에 따른 수리 모형을 제안한다. 또한 유전 알고리즘을 이용하여 예산 제한의 변화에 따른 총 가중 거리의 변화를 계산하여 경영진의 의사결정을 도울 수 있는 방법을 모색한다. According to the environment change of market, supply chain network needs to be redesigned for efficient provision of product within the budget constraint. Also, it is desired that the customer satisfaction such as on time delivery should be considered as an important element at redesigning of supply chain network in addition to the cost reduction. In this paper redesign of supply chain network for its expansion is treated as a problem situation and a related mathematical model is suggested. Moreover, the numerical examples about the total weighted distance of the redesigned supply chain network are presented with various budget constraints by using genetic algorithm to help the managerial decision.

The aim of gymnastics should be established in accordance with that of the school gymnastics and on this basis more effective plan should be made and carried out. It is necessxry to have certain facilities, tools, expense, and leaders. Staff members and students must be well orgamyed in order to carry on this smoothly. The works to do ofter athletic meeting are; to keep many tools and objects inorder, to clean the stadeum, to keep records, to give thanks to those who devoted to the meeting, to send letters of thanks to open the evalustion meeting of those concerned, to return many things borrowed. Ofter athletic meeting, it is necessary to keep score, and merits and faults of the game process so that the next meeting can be carred out more smoothly.

Thincking of the sports history in europe and the Orient we find that their peoples have concerened with the religion and social morality. In uncivilized people the sports teachings or educations didn't exist in the sports curriculum, but the way of living of clothing, eating, and housing gave them a good stimulation of the developments of qualities in body and bealth condition. Their old dances was for their pantomimes and wedding marches. With the imperial degree effected July 19th, 1895the western sports have got into the text-books in the primary schools in Korea. With the Korean Independence from Japan in 1945,and with the foundation of "Korean Sports Association",sports regular curriculum has adapted in Korean primary school, high schools, professional schools, and colleges. In China: From old time Chinese had worshiped their forefather and respected the teachings of the old. The old Chinese had lengthened their lives by protecting the body organs with the physical exercises and breath method. In India: Indians liked religions too much and didn't concern with the sports games or physical exercises. But they had only one sports style-yoga-,and it was a sort of controlling body conditions, asking for body postare or breath method. The sports in the old Greece; The old Greek was the first race(people)civilized highly. Greek's literature, polities, arts, and architecture have influenced upon all modern nations in the world. Greek had concerned with the bullfight games and sports festivals.
