ASSIGNMENT
Course Code :
MS - 05
Course Title :
Management of Machines and
Materials
Assignment Code :
MS-05/TMA/SEM-I/2015
Coverage :
All Blocks
Note: Please
attempt all the questions and submit this assignment on or before 30th April to
the coordinator of the study centre.
Q. 1. Explain in
detail the framework of planning, organizing and control decisions in
production systems. Give suitable examples to explain the framework.
Answer:A formal scheme for representing control in production systems is
defined. The scheme allows control to be directly specified independently of
conflict resolution and thus allows the issues of control and nondeterminisim
to be treated separately. Unlike previous approaches, it allows control to be
examined within a uniform and consistent framework. It is shown that the scheme
provides a basis for implementing control constructs which, unlike existing
schemes, retain all the properties desired of a knowledge based
system--modularity, flexibility, extensibility and adaptive capacity. Within
the formalism it is also possible to provide a meaningful
Q. 2. What are
the major techniques of work measurement? Discuss two important techniques with
suitable examples.
Answer: Work
measurement techniques are listed below:
·
Historical data method -
It uses the past performance data to set performance standards.Historical data
method uses the past-performance data. Here, past performance is used as a
guideline for setting work performance standards. The main advantage of this
technique is that it is simple to understand, quicker to estimate and easier to
implement. However, past performance is not the best basis for fixing
performance standards. This is because there may be many changes in

Q. 3. Under what
circumstances would you use PERT as opposed to CPM in project management? Give
some example of projects where each would be more applicable than the other.
Answer: Basically, CPM (Critical Path Method) and PERT (Programme Evaluation
Review Technique) are project management techniques, which have been created out
of the need of Western industrial and military establishments to plan, schedule
and control complex projects.
CPM/PERT:CPM/PERT or Network Analysis as the technique is sometimes called,
developed along two parallel streams, one industrial and the other
Q. 4.Explain the
basic concept of value engineering. Choose any product, system or procedure
that you are conversant with and apply the value tests to find out if there is
a scope for value improvement in it.
Answer:Value engineering (VE) is systematic method to improve the
"value" of goods or products and services by using an examination of
function. Value, as defined, is the ratio of function to cost. Value can
therefore be increased by either improving the function or reducing the cost. It
is a primary tenet of value engineering that basic functions be preserved and
not be reduced as a consequence of pursuing value improvements.
Q. 5.Explain the
following in brief:
a. Systematic
waste reduction procedure
Answer: Every unit of material sent to waste carries a
disposal cost. However the true cost of waste is more than just the cost of
disposal. It also includes the additional cost of raw materials, energy and
labour involved in making the product in the first place. This can be 5–20
times higher than the cost of disposal. So waste reduction programmes offer
businesses a double saving. Excessive
waste at the end of a product’s life is often due to the inefficient use of
resources when it was produced. Dealing with waste has an impact on the
environment so it makes sense to address the initial design of products to
sustain our natural resources and the
b. Wastivity
Indices
ANSWER : Wastivity indices are calculated for labour, material, energy, space, and
capital input. Productivity and wastivity are complementry to each other. The
productivity is improved by minimizing wastivity.Waste can be classified on the
basis of:
Waste Resources: Material resources like solids, liquids, and gases can
be wasted. Energy resources like physical, human and solar energy can be
wasted. Time resource can be wasted. Capital in the form of capacity,
equipment, machine
c. Gross
Wastivity:
ANSWER: A system
basically takes some input, process it and gives the desired output, as shown
in Figure 2 i.e., some input is essential, in whatever form, for the
functioning of a system. An ideal system is conceptualized to transform the
total input into useful or desirable output. In view of the known physical laws
of nature the existence of an ideal system is not possible, i.e. 100 per cent
utilization of resources is not practically possible for any system. To
paraphrase, some waste is inevitable in the functioning of any system.
d. Taxonomy of
waste:
ANSWER : Wastebasket taxon (also called a wastebin taxon, dustbin taxonor
catch-all taxon) is a term used in some taxonomic circles to refer to a taxon
that has the sole purpose of classifying organisms that do not fit anywhere
else. They are typically defined by their lack of one or more distinct
character states or by their not belonging to one or more other taxa.
Wastebasket taxa are by definition either paraphyletic or polyphyletic, and are
therefore not
