帮我写出如excel中的数学优化模型以及相关代码，并给出最优解

The data contains several columns with information such as:

- Task number (`任务号`)
- Duration in days (`工期（天）`)
- Start time (`开始时间`)
- End time (`结束时间`)
- Resource requirements for resource A (`对A资源要求（台天）`)

It seems the remaining columns may be empty or unimportant for this particular model.

If you're looking to create an optimization model, we can use this information to optimize scheduling or resource allocation. For example, we can formulate a model that minimizes the total project duration or resource usage while meeting the task constraints.

Could you clarify the specific goal of your optimization? For example:
- Minimizing project completion time
- Optimizing resource allocation (like minimizing the use of "台天")
- Ensuring tasks do not overlap based on start/end times

Once you confirm, I'll write the optimization model and the code in Excel-compatible format.

Learn how to optimize task scheduling and resource allocation using linear programming. This problem involves minimizing project duration and optimizing resource usage based on start/end times and task constraints. Suitable for university-level students.
