Session-5 Plant Layout / Facilities
layout Understanding the basic infrastructure
decisions of Operations Management.
Visit a retail unit, provide examples of
instances in which these rules were implemented ?
- Locate high-draw items around the periphery of
the store - Use prominent locations such as the first or last
aisle for high-impulse and high margin items - Remove crossover aisles that allow customers the
opportunity to move between aisles - Distribute what are known in the trade as power
items (items that may dominate a shopping trip)
to both sides of an aisle, and disperse them to
increase the viewing of other items - Use end aisle locations because they have a very
high exposure rate

U can choose to produce for 1 year at fixed level
of average demand with 100 people Or Chase
demand by hiring workmen when demand is more than
what can be produced by 100 workmen and
terminating when demand is less than what can be
produced by 100 workmen

worker Regular production cost per bag
Rs 2.00 Inventory
carrying cost Rs 0.50 per quarter
Production per employee 1,000 bags per
quarter Beginning
work force 100 workers
Which choice is cost effective? Produce at
fixed level of avg demand Or Chase demand by
hiring and firing

86Mixed Strategy
- Combination of Level Production and Chase Demand
strategies - Examples of management policies
- no more than x of the workforce can be laid off
in one quarter - inventory levels cannot exceed x dollars
- Many industries may simply shut down
manufacturing during the low demand season and
schedule employee vacations during that time

89Session-8 Resource Requirement Planning
(RRP) Nature and various systems for RRP ERP and
MRP I II systems used for Resource Requirement
Planning
- Resource Requirement Planning (RRP) is
Enterprise Resource Planning system based on 3
systems master production schedules, Material
requirement planning and capacity requirement
planning. -
Resource Requirement Planning (RRP)
Outputs Resource Requirement Planning
Inputs
Marketing Give short range Demand forecast
Master Production Schedule (MPS)
Production schedule- what month to produce what
item. Manpower schedule what month what
manpower Raw material Orders planned to be
released Raw Material/ Inventory status
(Beginning of period)
Finance Determine cash Availability
Material Requirement Planning (MRP)
Production Give production capacity Give norms
for inventory
Purchase Give production capacity Give norms for
inventory
Capacity Requirement Planning (CRP)
Engineering Specification of product
HR Availability of people
90Session-8 Resource Requirement Planning
(RRP) Nature and various systems for RRP ERP and
MRP I II systems used for Resource Requirement
Planning
91MRP Material Resources Planning
- Computerized inventory control and production
planning system - When to use MRP?
- Dependent demand items
- Discrete demand items ( not continuous demand)
- Complex products
- Assemble-to-order environments
92Materials requirements planning (MRP) is a means
for determining the number of parts, components,
and materials needed to produce a product MRP
provides time scheduling information specifying
when each of the materials, parts, and components
should be ordered or produced MRP is a software
93Class Work
What is the Material requirement plan for the
bag?
Lead Times A 1 day B 2 days C 1 day D 3
days E 4 days F 1 day
Total Unit Demand Day 10 50 A Day 8 20 B
(Spares) Day 6 15 D (Spares)
94Example of MRP Logic and Product Structure Tree
Given the product structure tree for A and the
lead time and demand information below, provide a
materials requirements plan that defines the
number of units of each component and when they
will be needed
Product Structure Tree for Assembly A
Lead Times A 1 day B 2 days C 1 day D 3
days E 4 days F 1 day
Total Unit Demand Day 10 50 A Day 8 20 B
(Spares) Day 6 15 D (Spares)
95First, the number of units of A are scheduled
backwards to allow for their lead time. So, in
the materials requirement plan below, we have to
place an order for 50 units of A on the 9th day
to receive them on day 10.
Lead Times A 1 day B 2 days C 1 day D 3
days E 4 days F 1 day
Total Unit Demand Day 10 50 A Day 8 20 B
(Spares) Day 6 15 D (Spares)
96Next, we need to start scheduling the components
that make up A. In the case of component B
we need 4 Bs for each A. Since we need 50 As,
that means 200 Bs. And again, we back the
schedule up for the necessary 2 days of lead time.
Lead Times A 1 day B 2 days C 1 day D 3
days E 4 days F 1 day
9797
Finally, repeating the process for all
components, we have the final materials
requirements plan
Lead Times A 1 day B 2 days C 1 day D 3
days E 4 days F 1 day
Total Unit Demand Day 10 50 A Day 8 20 B
(Spares) Day 6 15 D (Spares)
98Example of Time Fences
- Frozen
- No schedule changes allowed within this window
- Moderately Firm
- Specific changes allowed within product groups as
long as parts are available - Flexible
- Significant variation allowed as long as overall
capacity requirements remain at the same levels
99MRP Example
Requirements include 95 units (80 firm orders and
15 forecast) of X in week 10

105MRP Scheduling Terms
- Gross Requirements Total expected demand
- Scheduled receipts Open orders scheduled to
arrive - Planned on hand Expected inventory on hand at
the beginning of each time period - Projected available balance how many items
available at the start of plan - Net requirements Actual amount needed in each
time period - Planned order receipt Quantity expected to
received at the beginning of the period, keeping
in mind the lead time - Planned order release Planned amount to order
in each time period

110Session-9 Aggregate Planning, Nature and
objective, Operations Planning and Scheduling
System
- Main objective Specify the optimal combination
of - production rate (units completed per month or
week ) for example - Jan Feb March April May June
- 1000 1200 1250 2000 1500 1200
- workforce level (number of workers)
- inventory on hand (inventory carried from
previous period) - so that cost being least.
- This planning is done over an intermediate-range
planning period of 3 to 18 months

115Chase Strategy(Hiring Firing to meet demand)
Lets assume our current workforce is 7 workers.
116Below are the complete calculations for the
remaining months in the six month planning
horizon with the other costs included
117Level Workforce Strategy (Surplus and Shortage
Allowed)
Lets take the same problem as before but this
time use the Level Workforce strategy
This time we will seek to use a workforce level
of 6 workers
118Below are the complete calculations for the
remaining months in the six month planning horizon
Note, if we recalculate this sheet with 7 workers
we would have a surplus
119Below are the complete calculations for the

Note, total costs under this strategy are less
than Chase at Rs 260.408.62

Based on assumptions of forecast of demand, plant

assumptions go wrong, PPC is in
effective. Productivity standards may be set by
management but workmen may say that these norms
are too tough or wage needs to be increased. Low
morale may lead to poor quality , low safety and
delivery and higher costs. When external factors
change rapidly PPC is ineffective. 1. technology

129Process Analysis Terms
- Process Is any part of an organization that
takes inputs and transforms them into outputs. - Cycle Time Is the average successive time
between completions of successive units. - Utilization Is the ratio of the time that a
resource is actually activated relative to the
time that it is available for use.
130Process Performance Metrics
- Operation time Setup time
- Run time
-
- Throughput time Average time for a unit
to move through the system - Velocity Throughput time
- Value-added time
131Process Performance Metrics
- Cycle time Average time between completion
of units - Throughput rate 1 .
- Cycle time
- Efficiency Actual output
- Standard Output
132Process Performance Metrics
- Productivity Output
- Input
133Cycle Time Example
- Suppose you had to produce 600 units in 80 hours
to meet the demand requirements of a product.
What is the cycle time to meet this demand
requirement? - Answer There are 4,800 minutes (60 minutes/hour
x 80 hours) in 80 hours. So the average time
between completions would have to be Cycle time
4,800/600 units 8 minutes. -
