Selection of raw material manufacturers for hotel room consumables based on combined effects

With the continuous improvement of China's economy and life, the hotel industry is booming simultaneously. As a major management business for hotels, purchasing management of room consumables is crucial. In reality, hotels usually purchase multiple types of room consumables through supply middlemen, and there may be combined effects between these raw material products of consumables during the procurement process. This type of combined effects can enable hotels to increase efficiency and reduce costs in purchasing activities, and thereby influence their choice of manufacturer. Therefore, by studying the combined effect of purchasing room consumables and selecting the optimal manufacturer, the purpose of reducing hotel procurement costs and increasing revenue is achieved. This paper proposes a manufacturer selection algorithm for hotel room consumables based on combined effects. The raw material products can be combined into several groups with similar attributes by analyzing the combined degree of raw material products. Finally, the optimal manufacturer can be determined which meets the requirements based on the attributes of the combined groups.
