selecting an effective project plan is a significant area in the project management. the present paper introduces a technique to identify the project plan efficient frontier for assessing the alternative project plans and selecting the best plan. the efficient frontier includes two criteria: the project cost and the project time. besides, the paper presents a scheme to incorporate directed acyc...

State space and plan space planning approaches have traditionally been seen as fun-damentally different and competing approaches to domain-independent planning. Wepresent a plan representation and a generalized algorithm template, called UCP, for unify-ing these classical planning approaches within a single framework. UCP models planningas a process of refining a partial plan. T...

During the planning process, a planner may have many options for refinements to perform on the plan being developed. The planner’s efficiency depends on how it chooses which refinement to do next. Recent studies have shown that several versions of the popular “least commitment” plan refinement strategy are often outperformed by a fewest alternatives first (FAF) strategy that chooses to refine t...
