1. Формулировка задания. 
1.1. На рисунке 1 представлен сетевой график
1.1.1. Определите критический путь сетевого графика проекта, представленного на рисунке.
1.1.2. Рассчитайте резерв времени для начала и окончания работ 4-6

Рисунок 1. Сетевой график проекта
1.2. ИМЭМ разрабатывает проект по проведению ежегодных научных студенческих конференций. Решение о проведении конференции принято 01 сентября. Конференция должна пройти с 01 по 10 декабря. 
1.2.1. Определите вехи проекта 
1.2.2. Предложить показатели, характеризующие качество каждого этапа, обозначенного вехами.


To solve the provided task based on the uploaded network graph, I'll proceed with the following:

---

### **1. Solve Part 1.1.1: Determine the critical path.**
The **critical path** is the longest path in the network, meaning it determines the shortest time in which the project can be completed. This requires:

- Identifying all paths from node 0 (start) to node 11 (finish).
- Summing the durations along each path.
- Selecting the path with the greatest duration.

---

### **2. Solve Part 1.1.2: Calculate time reserves for activity 4–6.**
The **time reserve** (float) of an activity is given by:

\[
\text{Reserve time} = \text{Latest start} - \text{Earliest start}
\]

We calculate:

- **Earliest start and finish times** (using forward pass).
- **Latest start and finish times** (using backward pass).

Then, compute the reserves for activity 4–6.

---

### **3. Solve Part 1.2.1: Identify milestones (вехи).**
In project management, **milestones** are key events or completion points. From the provided context:

- Milestones typically represent the **start of the project**, **completion of phases**, and **project conclusion**.

---

### **4. Solve Part 1.2.2: Propose quality indicators for milestones.**
Quality indicators may include:

- Timeliness of completion.
- Resource efficiency.
- Stakeholder satisfaction.
- Achievement of intended outputs.

---

I'll now start solving these tasks. Do you have a preferred starting point, or shall I proceed sequentially from **1.1.1**?

1.1.1. Determine the critical path in the network graph.
1.1.2. Calculate time reserves for activity 4-6.
1.2.1. Identify milestones in the project.
1.2.2. Propose quality indicators for each milestone.

Analyze a project network graph to determine the critical path, calculate time reserves for activity 4-6, and identify key milestones. Learn about CPM and PERT methods with quality indicators for milestones. Suitable for undergraduate and graduate students.
