Front 1

Just-IN-Case = Push Sys

Back 1

Push Sys: Material & Parts R Push Next Process
Ready or Not
Materials R Released to Shop - Just-IN-Case- Where Needed Later on

Hint 1

Larger batch Manufact
Variation in Schdule & Inv Increases in each Upstream Process

Final Assembly build to exact demand

Batch & Queue Processing

Front 2

(JIT) = Just-IN-Time = Pull sys
Finite Loading = OPT= is a Procedure that Scdule WC base on Finite Loading

Back 2

Pull Required Materials
Value Stream &
Upstream Productions
Required 4 Delivery

Hint 2

Finite Loading
aimed at Producing High Qual & Low Cost , By eliminat wastes

Production Leveling
Final Assembly leveled to repetitive sequence & Quantity
Buffer Absorbs the customer's Schedule variations

Front 3

Machine Loading Allo job to wc & Commitment of Machine Time to Job

DIFF Between

Finite Loading Vs. Infinite Loading

Back 3

Finite = Sys Ck Prior Alloc for Capaci
before Commiting Capaci New Order.
CRP=Capaci Reqment Planni - Fuctions does it.
Also MRPII = Manu Reso Plan
JIT
OPT = Optimized Production Tech

Hint 3

Infinite = Sys Assigns Job to WC
Regardless of availa capacity.
W order tell WC - what need to b done
Not What can b Done
Under Normal situa
MRP= Material Reqmet Planning

Front 4

Sequencing Rules Mean:
(FCFS)= First Com-First- Serve
(EDD) = Earliest-Due Date

Back 4

FCFS = Determine Service Order

Used Job Sequencing First

Hint 4

EDD = Good 4 Reduce Ave Job Tardy
But - Does Not Generate - That Sequence of Job that exhibit the smallest Possible Ave Job Tar

Used Lowest DD First

Front 5

SPT is?

Shortest Processing Time

Back 5

SPT - Good 4 Min the Ave Flow T
4 a job residing in the Sys.
Mean less In-Process Inv &
Thus Less Shop Congestion
But- does Not Control Job Tard as Well as EDD

Hint 5

Used lowest Process T First

Front 6

CR is?
Critical Ratio
CR= Job Proces T/(Due Date- today's Shop Date
T=0CR = 11/15 =0.73 High # First
T=11CR= 12/22-11 = 0.55 H # Sec

Back 6

CR - Cal a CR each Time Sys is Ready to Process a Job
CR 4 each Remaining Job in quere

Hint 6

Highest CR = More Critical become = Their 4 it b Next
IF (Neg) = Job is late = so go Next
IF 2(NEG) = Low Process T First
CR = G4 Controlling Congestion & Providing Excellent Customer Service

Front 7

Repetitive Manufacturing is?

Back 7

Diff from job Shop Manu & Proc
Deal wt HI Vol, Standard Parts, Relatively Low Lead T &
Repeat Prod of Large Run Sizes

Hint 7

More Capacity-constrained Than Material-Constrained
Scheduling Techniques used:
MRP=Material Reqment Plan
MRPII=Manu Resour Plan
OPT= Optimized Proding Tech
JIT= Just in T
Combine above to complement each other

Front 8

Difff Between a Pull & Push
PULL = ACTUAL USAGE
PUSH = FOREC
Is one Better then the other one?
Pull Better

Back 8

Pull=(JIT)= Kanban
One Piece Flow- Ultimate
flow of mat is control
by replace only what has been consume
Product & Inv Pull just it time
to meet customer Demand
Tend to reduce or elimate Inv
bc high inv tend to cover up production Problem

Hint 8

Push=(JIC) =Traditional
Mater base on FORECAST or Sch
Mater Order base BEST GUESS of
What Customer Need in Future
Mater come in back door & r push
From oper to oper
into Ready to Ship
if customer still needed Them

Front 9

Master Routing Sheet
DEs

Back 9

Derived From Info from either the Ope Process chart or the Floor Process Chart
Must Exist for Each part, Assembly or Product
Showing The Sequence of Ope, Their Ope: #, Dept where work is Preform,
Their Set-Up-Time(if),
Production Time/Unit
Or Production Rate

Hint 9

With MRS: Workers Need The Product drawing & Specific Ope Instruction
on Quality & Process Control

Front 10

Gantt Chart
Des

Back 10

Displays Sequence & can
Show Where a WC
may be
over- or Under-
loaded

Hint 10

Grant Load Chart
Grant Sequencing Chart
Project Bar Chart

Front 11

Kanban Sys = Visual Production Control
Des
Conveyance kanban
Productions kanban

Back 11

Means Sing or Post Sys
Conveyance - parts moved from one process to the next Process

Hint 11

Production kanban- Production of parts at a Specific location.

Front 12

Visual Control
Des

Back 12

Sys of Symbols that conveys the right info to the right pep in timely manner.

object is to achieve mgmt by sight

Hint 12

Visual Production Control = Kanban & Gantt Chart
Visual Maintenance Control = Andons : lights tp reflect machine stoppage in the Process & Maintenance Load charts for PM & RM= Mar Azul

Visual Quality Controls= To observe variation is produced parts:
X-bar charts, R-charts & P charts

Visual Office Controls = Pitch Board & Office Labels.
Pitch Board= communicates work req, starting time of work, gets the work off the worker desk, work is scheduled in pitch increments , steers towards problem resolution when work does not get done on time

Front 13

Bottleneck is?

What it mean?
How pevents?

Back 13

are What ultimately constrain Manufacturing output

Hint 13

Mean that is preventing and out put form being produce.

By Identifying in advance & scheduling with this in mind

Determind what can be produce & when can it be produce

and schedule around them

to process only what can be absorbed by bottleneck machines within a reasonable time period, so as not to build excessive inventory or not to idle dottleck equicment
