本文利用PERT/CPM探討醫療器材製造產業研發專案中的時間和成本權衡問題。在專案管理中，專案經理人不僅需將專案控制在特定的時間內完成，同時亦需對於風險做良好的管理。而風險通常來自於專案的不確定性，連帶的其影響專案的成本與時間。為了使專案流程更加穩定和減少不確定性，本文將使用PERT/CPM來探討此問題。另也將套用實例並用網圖將專案各項活動間的關係做整體的瞭解，再利用線性規劃建立模式找出最佳的解決方案，並將變數之參數值進行敏感度分析。從研究個案結果發現當專案最佳完成時間為14週時，可達到最佳成本，其他情況下則會成本將會增加。最後，雖然PERT/CPM方法仍有許多需改善或補足的地方，但此實例卻顯示此方法仍能有效的幫助並給予參考當公司在評估專案之時間與成本。

This thesis discusses the using of PERT/CPM to assess the time and cost tradeoff in the R&;D phase of medical equipment production. The project managers not only have to implement the execution of the project in a specific time, but also need to handle the risk that might happen during the project. The risk usually arises from the uncertainty which affect project duration and cost. In order to make project more stable and reduce the uncertainty, the PERT/CPM method is used. This real case presents and uses project network to figure out the whole project process and relationship between each activities. Then, a linear programming model is formulated and solved to find out the optimal solution of the project, after that the sensitive analysis is present for further parameter analyze. The result of the case reveals that the optimal time is 14 weeks with the minimum cost. The cost will be increased when the time is reduced further. Finally, though the PERT/CPM techniques still have a lot of space to be improved in this case, this research could provide a good reference for the management to figure out the project completion time within a specific interval under reasonable cost.
