There are various approaches for inventory management. Of all the inventory control systems, ABC (Always, Better, Control) and VED (Vital, Essential, Desirable) matrix is most suitable for dental stores. We could not find any literature pertaining to inventory analysis in a private dental hospital. So, we conducted a study in a private dental hospital in Bangalore, Karnataka, India.
The present study aimed at evolving an inventory control plan for a private dental institution by categorizing the materials utilizing an ABC-VED coupling matrix.
The study analysed the annual consumption, the expenditure incurred for the dental consumables and developed a matrix based on ABC and VED analysis to narrow down the group of consumables for managerial monitoring.
Of the 215 consumables used 13.5% (A category) consumed 70% of total annual expenditure. About 21% of the consumables (Category B) consumed 20% and 65.5% (C category) accounted for 10% of the annual expenditure. The VED analysis found 47% consumables as vital, 37.6% as essential and 15.4% as desirable category. ABC-VED matrix analysis categorized 51.6%, 33.5% and 14.8% of consumables as category I, II and III, respectively.
Categorization by the ABC-VED coupling matrix model helps to narrow down on fewer consumables. The management of Category I consumables was monitored by top management resulting in better control on the annual expenses and at the same time making available the vital consumables. Category II was monitored by middle and Category III at lower managerial level.
库存管理有多种方法。在所有库存控制系统中，ABC（始终更好控制）和VED（关键、重要、期望）矩阵最适用于牙科诊所。我们未找到任何关于私立牙科医院库存分析的文献。因此，我们在印度卡纳塔克邦班加罗尔的一家私立牙科医院进行了一项研究。
本研究旨在通过使用ABC-VED耦合矩阵对材料进行分类，为一家私立牙科机构制定库存控制计划。
该研究分析了牙科耗材的年消耗量和支出，并基于ABC和VED分析制定了一个矩阵，以缩小用于管理监控的耗材类别范围。
在使用的215种耗材中，13.5%（A类）消耗了年度总支出的70%。约21%的耗材（B类）消耗了20%，65.5%（C类）占年度支出的10%。VED分析发现47%的耗材为关键类，37.6%为重要类，15.4%为期望类。ABC-VED矩阵分析将51.6%、33.5%和14.8%的耗材分别归类为I类、II类和III类。
通过ABC-VED耦合矩阵模型进行分类有助于缩小到更少的耗材。I类耗材由高层管理人员监控，从而更好地控制年度费用，同时确保关键耗材随时可用。II类由中层管理人员监控，III类由较低层级的管理人员监控。
