全民健保的實施，醫療市場更自由的被使用，由於政策的關係公家體系的醫院將無公務補助，而病例計酬與總額預算制度之施實，使得醫療機構間因財務之因素互相競爭趨向白熱化，所以各種體系醫院管理階層皆致力於提升手術室營運，病患亦期望得到適切的醫療服務與品質而且醫療院所邊際利潤減少，所以如何達到有效率管理減少成本耗用，增進內外顧客滿意度，加強醫療市場之滲透度，提昇財務績效，比對手更有競爭力，已成為醫療機構企業首要目標。
本研究以南部某醫學中心婦產科,婦科手術研究對象，主要探討住院病患手術之時間，應用對數常態(log-normal)分佈及相關統計方法，來討論手術房之利用率、超時機率來表現出最佳化之手術排程及相關成本分析，以期提供給院方做為未來經營的方針。

Appropriate utilization of the operating room (ORs) requires a balance of many conflicting resources. This cannot be done without an understanding of the role of the OR in the finances of the institution, the missions of the institution, the actual data concerning utilization and costs.
Economics of the OR environment have changed dramatically in the past 10 years. For example, technological advances have led to the introduction and advancement of minimally invasive surgical procedures, which are purported to decrease morbidity, reduce hospital length of stay, and improve outcome. However, many of these procedures actually increase OR cost, time and supplies. The increased costs of minimally invasive surgery would not have been a problem in the past, due to the additional costs would have been easily adsorbed because of the large profit margin associated with surgical procedure. Under the implementation of the NHI, the DRG, capitated payment, and global budget, it is not surprising that this area is earmarked by many hospitals as a place to reduce expenses. Therefore, all of us working in the OR must be cost efficient and maximize productivity for long-term success.
Accurate estimation of operating times is a prerequisite for the efficient scheduling of the operating suite. In this study, authors sought to compare surgeons’ time estimates for elective cases and to ascertain whether improvements could be made by statistical modeling.
The study was conducted in the GYN department at the VGHKS from 2000, Jan. to 2003, June. Author calculates operation time distribution (lognormal) and variance, and operation time finishing probability, costs, and comparing operating time difference between surgeons.
