Let's solve the expression step by step:

### Expression:
\[
10 \cdot (11 - 8) \div 2 + (1 + 3) \div 2
\]

1. **First, simplify inside the parentheses:**
   \[
   11 - 8 = 3
   \quad \text{and} \quad 1 + 3 = 4
   \]

   Now, the expression becomes:
   \[
   10 \cdot 3 \div 2 + 4 \div 2
   \]

2. **Next, perform the multiplications and divisions:**
   \[
   10 \cdot 3 = 30
   \quad \text{and} \quad 30 \div 2 = 15
   \]
   \[
   4 \div 2 = 2
   \]

   Now, the expression is:
   \[
   15 + 2
   \]

3. **Finally, add the results:**
   \[
   15 + 2 = 17
   \]

### Final Answer:
\[
17
\]
