When evaluating the question about the major assumption in determining the cost per unit of time to expedite each activity, it's important to unpack how expediting costs are typically modeled.
Option 1: 'A linear relationship between time and cost' — This option reflects the common assumption in many project management and cost-time optimization models, where reducing time ......Login to view full explanation登录即可查看完整答案

Question at position 2 P2. Scoreboard Installation You are a project manager working for the Cleveland Indians. Your project consists of installing a new scoreboard at Progressive Fields before Opening Day. You would like to find the minimum-cost schedule for the project. There is a $2,575 per week penalty cost for each week the project is delayed beyond 25 weeks. In addition, your project team determined that indirect costs are $3,500 per week. The minimum cost schedule is _________ weeks (enter response as integer).P2. Scoreboard Installation You are a project manager working for the Cleveland Indians.

Time–cost models attempt to develop a minimum- schedule for an entire project. 题目解析 X 正 在 帮 您 自 动 填 写 . . . Analysis of the True/False Statement The statement "Time–cost models attempt to develop a minimum-schedule for an entire project" is FALSE. Why the Statement is False Time-cost models aim to develop a minimum-COST schedule for an entire project, not just a minimum schedule. Key Points about Time-Cost Models They balance both time and cost factors. They aim to optimize the relationship between project duration and total cost. The goal is to find the most cost-effective schedule, not necessarily the shortest schedule. They consider trade-offs between time reduction and associated costs. Important Considerations Crashing activities (reducing duration) typically increases direct costs. The shortest possible schedule is not always the most economical. The model seeks an optimal balance between time and cost. Conclusion The statement is incorrect because it oversimplifies the purpose of time-cost models by focusing only on minimizing schedule without considering the cost aspect, which is a crucial component of these models. Therefore, the correct answer is FALSE because time-cost models are about optimizing both time AND cost, not just developing a minimum schedule. 点赞
