layout must be planned after keeping in mind their particular
requirements. The position of employees, that is, whether they remain
stationary or moving, also influences the layout. Employee facilities
such as health, locker rooms, public facilities and related services also
influence the layout significantly.
Machinery:-
The type of product, the volume of its production, the type
of process and management policy determines the size and type of the
machinery to be installed which, in turn, influences the plant layout.
Production is the combination and manipulation of men, materials and
machines. Before laying out a plant, it is necessary to determine
which of these elements are to be stationary or fixed as to location in
the plant and which will be mobile during the process of production.
2. State the function of production management. (Same as 4).
Nov-06
Repeated Question: - (1)3. Explain the importance of systems approach to production
management.
October/Novmeber-024. Define production management. List important areas of it. State the
function of any one area.
Ans. Production Management:-
It refers to the application of management principles to the
production function in a factory. In other words, production management
involves application of planning, organizing, directing and controlling to the
production process.
The important areas of it are as follows:
i. Improving the volume of production.
ii. Reducing the rejection rate.
iii. Minimizing re-work rate.iv. Maintaining the delivery schedules.
v. Controlling the idle machine and manpower hours.
vi. Establishing/updating/improving/setting industrial
engineering norms.
vii. Updating processes and procedures.
viii. Maintaining accuracy and timelines of MIS.

ix. Decreasing machine set-up time.
x. Controlling overtime.
xi. Good house-keeping.
xii. Checking absenteeism, thefts/pilferage and misconduct.
xiii. Eliminating the accidents.
xiv. Effective grievance handling.
xv.Efficient training and team building.
xvi. Minimizing inventory and achieving better yields.
xvii.Enhancing the customer satisfaction.
xviii. Total Quality Management (TQM).
xix. Business Process Re-engineering (BPRE).
xx. Automation.
5. Compare the batch production and mass production.Ans.
Batch Production/ Unit Production Mass Production
a). In this type, the product is
produces in the same batches.
a). In this type of production, the
production is continues throughout.
b). Same type of product is repeated
for many time in the industries.
b). Once the machine is set-up, there
is no need to adjust it for a long time
period.
c). If the design of product or
measurement will change there willbe accordingly changes in set-up and
instruction.
c). Once the production instruction is
given, the work is going straight andsystematically.
d). As per time variation, lots of
changes implement in machine and
method.
d). Raw material storage is
compulsory in this type of
production otherwise production will
stop.
e). The new product will be dispatch
in the market within certain batches.
e).Examples: Electronic industry,
watch industry, Bearing industry,
Electrical goods industry.
f). Examples: medicine industry,shoes industry, furniture,
Automobiles, Imitation item.
f).Apart from this process industry isalso a type of Mass Production. It
also includes chemical and food
products such as cement, sugar, food
products, fertilizer, petrochemicals.

6. State the application of job shop production. Also state its merits and
demerits.
Ans.
Number of jobs produced: 01 to 05 only.
In this production method, a production is as per the customer order.
At the time period there will be variety in the product.
As per customer order specification, set up and instruction will be
changed.
No requirement of stock storage in this type of production.
Production is done as per customer order.
Examples: ship building, casting industries, aircraft industries,
machine tool manufacturing, process industry equipment.
Advantages:
a) Getting more information regarding new technology.
b) No requirement of inventory control so the cost is reducing.
c) Skill of worker is increasing.
Disadvantages:
a) There are lots of difficulties due to not awareness about new
technology
b) A special skilled worker is required.
c) For every new product a worker has to give special training.
7. Differentiate between data and information. Also state various types
of data.8. State and explain features of DBMS.

i. If 3 months moving average is used to forecast the next
months demand, calculate the forecast of sales in the month of
July-05.
ii. Calculate a weighted three months moving average for the
month of July-05, where the weights are 0.5 for the least
month, 0.3 and 0.2 for the other months respectively.

Nov-0612.Explain noise in demand. Explain independent verses dependent
demand.
Ans.
Independent Demand:
Demand for a material that is independent of the demands for
other materials. For example, demands for end products are independent
of demand for parts, raw material or components as their demands are
determined, by customers outside the organization.
Dependent Demand:
Demand for a raw material, part or a component, that is
dependent on the demand doe the end product in which these materials
are used.
13.Explain Mean Absolute Deviation (MAD) and Bias with respect to
forecasting error.
Ans.
Mean Absolute Deviation (MAD):-
A forecast error measure that is the average
forecast error without regard to direction, calculated as the
-
8/7/2019 SA 606 -P.M.I.S
6/25
sum of absolute value of forecast error for all periods divided
by the total number of periods evaluated.
For each period (l), you find the difference between
the forecasted demand and the actual demand. If your forecast
was perfect actual demand equals the forecasted demand, and
the forecast error is zero. As forecasting continues, the forecast
error is recorded and accumulated, period by period.
Notice that MAD is an average of the absolute value
of forecast error; errors are measured without regard to sign
Mad expresses the magnitude but not the direction
error. This measure of absolute values is called absolute
deviation.
BIAS:-
A forecast error measure that is the average of
forecast error with regard to direction and shows any tendencyconsistently to over or under forecast; calculated as the sum of
actual forecast error for all periods divided by the total
number of periods evaluated.
Unlike MAD, BIAS indicates the directional
tendency of forecast errors. If fewer forecasts repeatedly
overestimate actual demand BIAS will have a positive value
consistent under estimates will be indicated by a negative
value.

Sequence the jobs at grinding shop based on minimum critical ratio.
21.Write brief note on Master production schedule (MPS).
Ans.
This is the schedule of the quantity and timing of all end
products to be produced over a specific planning horizon. MPS is
developed from customers firm orders or from forecast of demand or
both. It is an input of the MRP system.
The MPS specifies what end products are to be produced andwhen. The planning horizon should be long enough to cover the
cumulative lead times of all components must be purchased or
manufactured to meet the end product requirements.
22.How material requirement planning (MRP) is useful in production
management.
23.Explain Manufacturing resource planning (MRP II).
Ans. When the capabilities of closed-loop MRP (Material
Requirement Planning) are extended to integrate financial, accounting,
personnel, engineering and marketing information along with the
production planning and control activities of the basic MRP system, the
resulting broad-based resource-coordination system is known as
manufacturing resource planning or MRP-II. It is the heart of the
corporate management information system for many companies, as it
provides information about inventory investment levels, plant expansion
needs, and work-force requirements, which is useful for coordinating
marketing, financial, engineering and manufacturing efforts to achievethe companys overall business plans.
The projection of what materials and components will be
purchased and when, can be used to develop purchase commitments and
a projected purchasing budget. The labour hours projected in the capacity
requirement plan for each work center can be aggregated to develop
