ABSTRACT: - This paper represents the practical applications of fuzzy set theory in the predicting delay in construction
industry. The construction industry is one of the most important aspects of a civil engineering structure. The fuzzy set theory is an
important part of construction industry. The fuzzy sets are the sets which are introduced by Lotfi a Zadeh and Dieter Khana in
1965. There are many construction problems in a construction industry which effects on the construction in different wages, like
delay in construction, construction cost, material used on side etc. due to these problems, we caused delay in construction. there
are many methods which estimation the delay duration of activity in a construction industry. The fuzzy set theory is one of them.
This method helps us to minimize the product of sum of the membership association for a certain frequency of occurrence and
corresponding frequency of occurrence. The CPM (critical path method) and PERT (Program Evaluation and Review Technique)
are used in the activity delay. Fuzzy logic provides a simple way to solves a definite conclusion based upon vague, missing input
information. The fuzzy logic is a form of value is deal with the reasoning i.e., approximate rather than fixed.
Keywords: - CPM, PERT, Fuzzy logic, Delay, Construction problem.
1. INTRODUCTION
The fuzzy set theory plays an important part in
the construction industry, it has been studying over the
last 50 years. The fuzzy logic set theory is introduced by
the zadeh in his paper on Fuzzy set. the fuzzy logic set
theory is now applied to problems in construction
engineering, business, medical, related health sciences, and
the natural sciences etc. In an effort to gain a better
understanding of the use of fuzzy logic set theory in
construction industry management research and to
provide a use for future research, a literature review of
fuzzy set theory
in construction industry management has been conducted.
In 1956, the critical path method (CPM) was implemented
on a computer to schedule construction project. In 1957, a
technique implements called the program evaluation
review technique (PERT) has developed to integrate the
coordinate contractor working on a single project.
Recently a method called graphical evaluation and review
techniques (GERT) was developed. It is the simplest
method to say the dovetailed in the construction industry.
It is useful when performance of all the operations is not
necessary for the completion of projects.
All the methods used in the fuzzy set theory has been
totally divided into different two groups deterministic and
probabilistic. When the information is used for a particular
method and which is known during the analysis is called as
deterministic, the critical path method and bar chart is
define as the deterministic. In the probabilistic method
every parameter is generally expressing in terms of mean,
coefficient of variation, standard deviation etc. program
evaluation and review technique, and graphical evaluation
and review technique can be classified as a probabilistic
method.
However different probabilistic method is used with
various degrees of complexity in construction engineering.
Now day parameter is expressed in mathematical term,
because classical probability theory fails to inaccurate the
information. So these linguistic variables can be used in a
mathematical form by fuzzy sets and system theory. The
all problem related to weather and labor delay can be
solved in paper using these concepts of fuzzy sets theory.
2. LITERATURE REVIEW
The various literatures are studied to
get an overview of the factors responsible for a
construction delay in the construction industry and we
studied the various uses of the fuzzy logic set theory in

various fields. This paper helps me to understands the
fuzzy logic set theory.

“Delay Computation Using
Fuzzy Logic Approach” the author use the fuzzy logic set
theory, which helps the author to find out the total delay
duration on the construction site. Initially the research is
based on the real project executed in Gwalior (mp), and
find the delay duration due to shortage of materials and
lack of operators. after that the author apply the fuzzy set
theory on project with linguistic and membership values.
The writer gets the nearly same value in his research.

“The project scheduling
using fuzzy set concepts” this paper analyzed the project
scheduling method using fuzzy set which helps us to find
out the delay duration in any completed project. In this
paper author use the linguistic function along with
membership function to find out the delay duration in any
project. one of the important use of this technique is that it
can be easily implemented in existing computer programs
for project scheduling.

“APPLICATION OF FUZZY LOGIC
IN DELAY ANALYSIS IN CONSTRUCTION” this paper
represents the application of fuzzy logic in analysis of
delays in construction industry using fuzzy toolbox of
MATLAB program software. The author takes the different
factor of delay labor related, project related, consultant
related, contractor related, external factor, owner related,
material related, environment related, design related,
equipment related etc. a case study and an interview was
done by a author in housing project in Gwalior ,to
determine causes of delay with a help of questionnaire
survey. The value of factor ranging from 1 to 100 as a
probability of schedule delay (01 for very low and 100 for
very high).

“A FUZZY MODELING
APPROACH TO WEATHER DELAY ANALYSIS IN
CONSTRUCTION PROJECT” the author use the same
process which is used by the Bilal M. Ayyab and Achintya
Haldar in his research paper but after that the author
compare the different weather with the different activities.
The time impact analysis for different delay analysis can be
used.

“Fuzzy logic approach for Activity Delay
Analysis and Schedule updating” the research aims to
make a fuzzy logic model for modifying activity durations
and the model integrates daily site reporting of activity
progress and delays with a schedule updating and
forecasting system for construction project monitoring
and control.
3. CONCLUSION
The critical review undertaken in this paper
covers total effect of delay, and seen the different method
of finding out the delay duration in different wages. The
other authors used the different methods like RII, AHP etc,
but in this paper we used the fuzzy logic set theory for
determine the delay duration.
