Module 5 - Section A: Detailed Schedules

Question 1

Operation Setback Chart

Answer 1

-type of scheduling tool

-product structure, routing, and lead time data used to develop operation setback chart for master-scheduled end items

-graphical display of bill of materials and lead-time info provided by routing for each part

-horizontal axis provides lead time from raw materials purchase to component manufacture to assembly of the finished product

Question 2

Control Board

Answer 2

visual means of showing machine loading or project planning

-also called the schedule board, planning board, or dispatch board

-challenging to keep up to date and to communicate to shop floor

Question 3

Job Shop Scheduling

Answer 3

-one of the production planning and control techniques used to sequence and prioritize production quantities across ops. in a job shop/work center manufacturing process type

-deal with typically small order quantities, lack of knowledge of what needs to be scheduled until actual orders come in, and complexities of multiple shared resources and varied routings and materials

-many job shops employ drum-buffer-rope (resource-limited scheduling) to help minimize bottlenecks that may shift on a daily basis

Question 4

Block scheduling

Answer 4

-an operation scheduling technique where each operation is allowed a block of time, such as a day or week

-often used in service industries (and in school systems) as a way to ensure that the larger blocks of time that are available in a schedule aren’t consumed by smaller appointments

example: one schedules the large blocks of time first, such a a 3 hour dental surgery, and then fills in the smaller items in the remaining gaps

Question 5

Throughput

Answer 5

-rate at which system generates goal units

-expressed for a given time period e.g. month, week, day

-if goal units are money, throughput is an amount of money per time period

Question 6

Visual Management

Answer 6

-management system whereby every metric that matters, standardized work, and improvement approaches are displayed on the shop floor and in the office

Question 7

Flow Rate

Answer 7

-running rate

-inverse of cycle time

example: 360 units per shift (or 0.75 units per minute)

-tends to be slower in batch processing due to lack of specialization of machinery and workers

Question 8

Production Rate

Answer 8

-rate of production usually expressed in units, cases or some other broad measure, expressed by a period of time (e.g. per hour, shift, day, or week)
