Batch Processing Scheduling
Batch Processing Scheduling problems involve processing multiple jobs simultaneously in batches, where a machine can handle up to a certain number of jobs per batch. You need to calculate the minimum total processing time.

Introduction to Batch Processing Scheduling
Batch Processing Scheduling problems involve processing multiple jobs simultaneously in batches, where a machine can handle up to a certain number of jobs per batch. You need to calculate the minimum total processing time.
Prerequisites
How to Solve Batch Processing Scheduling Problems
Step 1: Number of jobs = N, batch capacity = B
Step 2: Number of batches = ceil(N / B)
Step 3: Processing time per batch = T
Step 4: Total time = number_of_batches × T
Step 5: Answer with total time
Example Problem
Example: 17 jobs, batch capacity 5, each batch takes 30 minutes. Minimum total time? Solution: Step 1: N=17, B=5, T=30 Step 2: Batches = ceil(17/5) = ceil(3.4) = 4 batches Step 3: Total time = 4 × 30 = 120 minutes Answer: 120 minutes
Pro Tips & Tricks
- Number of batches = ⌈N/B⌉
- Ceiling division: ⌈a/b⌉ = (a + b - 1) // b for integers
- If N is multiple of B, batches = N/B
- If jobs have different processing times, batch time = max time in batch
- Parallel machines can process multiple batches simultaneously
