Flow operations
Processes designed to handle high-volume, standard products.
Routing
Provides information about the operations to be performed, their sequence, the work centers, and the time standards.
Infinite loading
Scheduling that calculates the capacity needed at work centers in the time period needed without regard to the capacity available to do the work.
Finite loading
Scheduling that loads work centers up to a predetermined amount of capacity.
Forward scheduling
Schedule that determines the earliest possible completion date for a job. Due date Time when the job is supposed to be finished.
Backward scheduling
Starts with the due date for an order and works backward to determine the start date for each activity.
Slack

Job lateness

Job tardiness
Measures how long after the due date the job is completed.
Optimized production technology (OPT)
A technique used to schedule bottleneck systems.
Theory of constraints (TOC)
A management philosophy that extends the concepts of OPT.
Internal resource constraint
A regular bottleneck.
Market constraint
The condition that results when market demand is less than production capacity.
Policy constraint
The condition that results when a specific policy dictates the rate of production.

Getting the right quantity of goods at the right place at the right time.
Waste
Anything that does not add value.
A broad view of JIT
A philosophy that encompasses the entire organization.

Broad view of operations, simplicity, continuous improvement, visibility, and flexibility.
Types of waste

Visibility
Problems must be visible to be identified and solved.

The three elements are just-in-time manufacturing, total quality management, and respect for people.
