博士 / 東海大學 / 工業工程與經營資訊學系 / 103 / The purpose of this dissertation was in order to achieve optimal operating performance of the financial aspect target and combined decision-making analysis and lean management tools to assist the case study of hospital to implement the vendor managed inventory (VMI). In literature review, this chapter was summarized the implement process and decision-making analysis tools of various stages of lean management and drawn the current status of value streaming mapping (VSM) in the pre-implement stage to assist the hospital were successfully implemented VMI. Finally, this dissertation was through the discussion of practical case studies to verify that a feasibility of architecture hospital process improvement is applied.
First of all, analytic hierarchy process (AHP) was adopted to analyze the critical factors of the implementation for VMI. The most important of critical factor was “lead time” and the priority of others were followed by “material centralized management”, “shorten operating time”, “service level” and “internal/external processes integration”. Next, lean six sigma was used to the aforementioned major critical factors related to the process improvement and in the case hospital after implementing VMI, on the implementation of the results of the key performance indicators (KPI) tracking analysis. The KPIs of units of the department of surgery were analyzed by paired t-test, “uncentralized procurement ratio" and "VMI procurement ratio" had a very significant difference (p value <0.01), "the average lead time" and "inventory turnover rate" did not differ. Finally, data envelopment analysis (DEA) was used to assess the relative efficiency of each unit of the department of surgery, Neurosurgery only achieved to relative efficiency in 2012. In 2014, there increased in cardiovascular surgery, general surgery, orthopedic and chest surgery, four units achieved to relative efficiency. The KPIs of storeroom in the operating room, either “uncentralized procurement ratio", "VMI procurement ratio", "the average lead time" and "inventory turnover rate" also had improved, and to use DEA to assess the implementation of VMI before and after overall operating efficiency had significantly improved.
In this dissertation, the empirical results investigated whether the hospital can improve its inventory management performance and operating efficiency after the implementation of VMI. It was found only after the implementation of VMI could significantly enhance the performance of its inventory management, its operating efficiency also had a positive impact, and while reducing transaction costs and save unnecessary expenses. Therefore the results of this dissertation may provide other hospitals or other healthcare industry as a reference to implement VMI.
