碩士 === 朝陽科技大學 === 營建工程系碩士班 === 91 === There are two objectives on the construction project resource scheduling: (1) to let all of the activities get their resources and then complete the works before the required finish date considering cost problem;(2) to make resource allocation and utilization efficiently to reduce the delay possibility of the works when the capacity; For achieving the objectives on construction project resource scheduling and cost minimization, this research offers a new model to solve the problems above. The traditional models still have many problems to solve this sort of problems.(i.e the speed of searching feasible solutions, etc,. ). Consequently, In this research we propose a model for solving project time/cost tradeoff problem under the constraint of limited resources using tabu search algorithm and makes some improvement on the disadvantages of traditional models in my study. Furthermore, this model will be more stable and efficient than the studies did before. The study implements the concept of Tabu Search algorithms(TS) to build a new model considering time/cost tradeoff problem. TS method achieves superior results compared to the other methods because it is based on introducing flexible memory structures in conjunction with strategic restrictions and aspiration rules as a means for exploiting search spaces. After the experimental test of the model the research propose, the result of the test compared the similar studies is good.
