In recent years, business environment is faced with multi uncertainty that have not been suffered in the past. As supply chain is getting expanded and longer, the flow of information, material and production is also being complicated. It is well known that development service industry using application software has various uncertainty in random events such as supply and demand fluctuation of developer’s capcity, project effective date after winning a contract, manpower cost (or revenue), subcontract cost (or purchase), and overrun due to developer’s skill-level. This study intends to social contribution through attempts to optimize enterprise’s goal by supply chain management platform to balance demand and supply and stochastic programming which is basically applied in order to solve uncertainty considering economical and operational risk at solution supplier. In Particular, this study emphasizes to determine allocation of internal and external manpower of developers using S&OP (Sales & Operations Planning) as monthly resource input has constraint on resource’s capability that shared in industry or task. This study is to verify how Stochastic Programming such as Markowitz’s MV (Mean Variance) model or 2-Stage Recourse Model is flexible and efficient than Deterministic Programming in software enterprise field by experiment with process and data from service industry which is manufacturing software and performing projects. In addition, this study is also to analysis how profit and labor input plan according to scope of uncertainty is changed based on Pareto Optimal, then lastly it is to enumerate limitation of the study extracted drawback which can be happened in real business environment and to contribute direction in future research considering another applicable methodology.

한국수자원공사는 낙동강 및 금강수계에 대해 실시간 물관리 시스템을 개발하여 수계 내 다목적 댐의 효율적인 운영을 도모하였다. 본 연구에서는 이를 확장하여 최적화 기법인 표본 추계학적 동적계획법을 사용하여 한강수계 다목적댐의 효율적인 월말 목표저수량을 산정하고 이를 통해 실시간 물관리시스템의 효율을 극대화하고자 수행되었다. 수계 내 댐중 저수용량과 용수공급 측면에서 중요도가 높은 소양강댐, 충주댐, 화천댐 등 3개 댐만을 대상으로 모형을 개발하였으며 저수

저수지 운영의 기초가 되는 운영률은 대부분 과거기록 유입량중 최대 혹은 최소의 극한치 자료를 이용하거나 평균치 자료를 이용하여 도출하기 때문에 실제 운영에서 발생할 수 있는 불확실성에 대처한 기대편익 산정이나 운영방안 수립에는 적절히 이용할 수 없다. 또한 지금까지 개발된 대부분의 운영률은 유입량을 포함하여 모든 운영변수를 이미 알고 있다는 확정론적 방법에 기초하고 있어 유입량의 불확실성을 반영하지 못하는 단점이 있다. 이를 개선할 수 있는 방법으로 추
