Activity Relationship Analysis & Dimensionless block diagram
Dimensionless block diagram has flow diagram drawn on it
- How close things (office, department and service facility) should be to eachother based on their
relationship and how important it is for them to be nearby one another for an efficient flow
Ex. Employee flow:
from parking lot to employee entrance, to time clock, to lockers, to cafeteria, to work area
- To create most efficient layout
Analysis Relationship Analysis
- Shows relationship of every department, office or service area w every other
- Ases uestio ho ipotat is it fo this depatet, offie or service facility to be close
to aothe
Closeness codes:
A – absolutely necessary
E- especially important
I-important
O-ordinary importance
U- unimportant
X- closeness undesired

A- Massive amounts of material btwn departments
A- Need for great number of people moving – maintenance and the tool and suppliers crib
E- code when in doubt of A code – most of the time occurances, not all the time (restrooms)
U- no activity or interference is needed between the two departments
- Ie. Paint and tool room explosions – bad
- A and X are equally as important
- X noise, smell, heat, dust, cold
- Reasons code key – 1/2/3
FMP
1) Flow, material moves, ppl
- Shipping and receiving not close to eachother
- Qualitative and quantitative components to facilitate the assignment of codes
- Flow lines between the two activities codes to depict the movement of the parts or people,
number of lines or intensity of the flow – indicate the desired degree of closeness
- Or assign arbitrary values to relationship codes
- Qualitative based on expert opinions and the judgement of individuals
- Do not exceed the percentages of assigning in the chart:
1) Percentages increase in ALPHA ORDER ; ie. Sooner letter less parentage
▪ Start at A=5%
2) INC BY 5, start at A; A->E inc by 5; E-I inc by 5; EXCEPTION I O; inc by 10
3) The remaining assigned to U
- Total number of relationship codes = N
- N= n(n-1)/ 2
- Where n=number of departments or work centers
- Worksheet= not necessary- summary of activity relationship chart
