Chapter 19Operations Scheduling
  • Work Center Defined
  • Typical Scheduling and Control Functions
  • Job-shop Scheduling
  • Examples of Scheduling Rules
  • Shop-floor Control
  • Principles of Work Center Scheduling
  • Issues in Scheduling Service Personnel
work center defined
Work CenterDefined
  • A work center: an area in a business in which productive resources are organized and work is completed.
  • May be a single machine, a group of machines, or an area where a particular type of work is done.
capacity and scheduling
Capacity and Scheduling
  • Infinite loading (Example: MRP)
  • Finite loading
  • Forward scheduling
  • Backward scheduling (Example: MRP)
typical scheduling and control functions
Typical Scheduling and Control Functions
  • Allocating orders, equipment, and personnel.
  • Determining the sequence of order performance.
  • Initiating performance of the scheduled work.
  • Shop-floor control.
priority rules for job sequencing
Priority Rules for Job Sequencing

1. First-come, first-served (FCFS)

2. Shortest operating time (SOT)

3. Last-come, first served (LCFS)

4. Earliest due date first (EDD)

Many other possible rules...

schedule performance measures
Schedule Performance Measures
  • Meeting due dates
  • Minimizing the flow time
  • Minimizingwork-in-process
  • Minimizingidle time
example of job sequencing first come first served
Example of Job Sequencing: First-Come First-Served

Suppose you have the four jobs to the right arrive for processing on one machine.

What is the FCFS schedule?

Answer: FCFS Schedule

shop floor control major functions
Shop-Floor Control:Major Functions

1. Assigning priority of each shop order.

2. Maintaining work-in-process quantity information.

3. Conveying shop-order status information to the office.

shop floor control major functions continued
Shop-Floor Control:Major Functions (Continued)

4. Providing actual output data for capacity control purposes.

5. Providing quantity by location by shop order for WIP inventory and accounting purposes.

6. Providing measurement of efficiency, utilization, and productivity of manpower and machines.

Input/Output Control
  • Planned input should never exceed planned output.
  • Focuses attention on bottleneck work centers.
