3.3. : * A set of jobs, each with a processing time on each machine and a routing that specifies the order in which the machines must be visited. * Goal: Schedule the jobs on the machines to minimize the makespan. * Goal: Schedule the jobs on the machines

| Job | Machine 1 | Machine 2 | Machine 3 | | --- | --- | --- | --- | | 1 | 3 | 2 | 1 | | 2 | 2 | 3 | 4 | | 3 | 1 | 4 | 2 | | 4 | 4 | 1 | 3 | | 5 | 3 | 2 | 1 | Please let me know if you need any further assistance

3.2. : * A set of jobs, each with a processing time on each machine. * Goal: Schedule the jobs on the machines to minimize the makespan, subject to the constraint that the jobs must be processed in the same order on all machines.

A scheduling problem has 3 machines and 5 jobs. The processing times are:

1.2. : * Define the decision variables: $x_ij = 1$ if job $j$ is scheduled on machine $i$, and $0$ otherwise. * Define the objective function: Minimize $\max_j (C_j - d_j)$, where $C_j$ is the completion time of job $j$ and $d_j$ is the due date of job $j$. * Define the constraints: + Each job can only be scheduled on one machine: $\sum_i x_ij = 1$ for all $j$. + Each machine can only process one job at a time: $\sum_j x_ij \leq 1$ for all $i$. + The completion time of job $j$ is the sum of the processing times of all jobs scheduled on the same machine: $C_j = \sum_i p_ij x_ij$.
