IN
QUALITY, RELIABILITY AND OPERATIONS RESEARCH
PREMABLE
The Indian Statistical Institute initiated the use of Statistical Quality Control and Operations Research in India in the early fifties and started developing these fields through theoretical and applied research, practical training in industry and consultation work. Recognising the need for trained manpower by the industry for conserving the scarce resources in the country through the application of scientific techniques, the Institute started a full-time advanced one-year course in SQC and OR at the post-graduate level in 1964. Later on, this course was converted to a Post Graduate Diploma in SQC and OR of fifteen months’ duration. The Institute also introduced SQC and OR as a field of specialisation in the M.Stat programme in late 1960s, and since then offered the specialisation to meet the growing needs and demands for such specialists from the industry. Meanwhile, significant changes were brought about in our economy with import libaralisation, export thrust and restructuring since late eighties. These changes coupled with the advent of up-to-date quality management and assurance system standards (such as ISO 9000 series) worldover gave an unprecedented thrust for quality improvement of products and services in our country. The demand for trained quality professionals grew. To meet this demand, the Institute started a two-year full-time M.Tech programme in Quality, Reliability and Operations Research in Calcutta, in 1989, in place of the earlier P.G. Diploma in SQC and OR. Besides the above programme, Institute also offers a two year part-time Post-graduate Diploma course in SQC and OR at Chennai and Mumbai and a six month evening certificate course in SQC & OR at Bangalore and Hyderabad for supervisory staff sponsored by their organisations
The course structure, the curriculum and the method of instruction have been continually reviewed and updated taking into consideration the feedback from our students, faculty and the respresentatives from industries in keeping with the changing needs and emphasis of the industry on using most up-to-date quality assurance and management systems (such as, ISO 9000, QS 9000, ISO 14000, TQM etc.) and computers (online and offline)
The Master of Technology in Quality, Reliability and Operations Research is a full time programme and is offered at Kolkata. This programme is intended to produce specialists in Quality Management with emphasis on Statistical Quality Control, Reliability, Operations Research, Computer Software and Management Systems. The programme is designed to offer adequate instruction in the theory and practice of the above disciplines. The objective is to equip students with the basic practical skills with sufficient theory to understand the principles involved in the application and to develop in them the power of systematic thinking and reasoning, practical approach and exposition. Every student, besides undergoing classroom instruction, shall do practical work by way of case studies,dissertation and project work on live problems in factory under the guidance of the expert faculty of ISI. On successful completion of this programme, the students may take up either
The duration of the course is two years, inclusive of the period of factory training at the end of the first year during the summer and a period of project and dissertation work in the semester IV the second year of the programme. The practical training for the project will be offered at different centres of the SQC and OR Division. During the practical training, the candidates are required to work on live plant problems and to submit project reports which form a part of the curriculum. The field trainings are, as far as possible, arranged in industrial establishments which are clients of the different SQC and OR Units of the Institute. However, where the Institute is not able to arrange training in such plants, the sponsoring organisations should provide training facilities for their nominees either in their own plants or in other plants approved by the Institute. The deputation of a candidate to any plant is at the sole discretion of the Institute
.
A candidate seeking admission to this course should
Mathematics (at graduate level) and knowledge of Physics and Chemistry (at the higher secondary level) ;
The programme is offered in two streams: Statistics stream and Engineering stream. The candidates with qualifications as in (a), (b) or (d) above are administered admission test in Statistics and Probability, whereas, the candidates with Bachelor’s/equivalent degree in Engineering as in (c) above are administered admission test in Mathematics and Engineering for their admission, (if selected, to the first year of the course in Statistics and Engineering streams respectively). However, the exact nature of the admission test will be decided by an appropriate selection committee.
Admission is based strictly on merit assessed through academic record and performance in the written/oral admission tests and interviews. There is however a provision for admitting a few eligible candidates sponsored by their employers. Advertisements announcing the commencement of the programme and inviting applications for admission are issued around January/February every year in nationally circulated newspapers. Eligible candidates, including sponsored candidates, are required to appear at written/oral selection tests and interviews during May/June. However, sponsored candidates may be admitted on the basis of their suitability alone and not on a competitive basis as may be decided by the Selection Committee at its sole discretion.
Industrial organisations can sponsor candidates from their establishments for this programme provided they satisfy the eligibility requirements.
The Master of Technology in Quality, Reliability and Operations Research is conducted in four semesters, two semesters each in the first and second years. The courses for study and examinations in each semester are as follows.

GENERAL RULES, METHOD OF EXAMINATIONS AND AWARD OF DEGREE
For each course there are two examinations, mid-semestral and semestral (final), except for the courses Dissertation, Project - I and Project - II. The composite score in a course is a weighted average of the scores in the mid-semestral and semestral examinations, home-assignments, practical record-book, etc. (announced at the beginning of the semester). For courses other than Dissertation, Project - I, Project – II, Workshop - I and Workshop - II, the minimum weight given to the semestral examination is 50%.
The attendance requirement is 75% for each course in a semester. If a student fails to attend classes in any course continuously for one week or more, he/she will be required to furnish explanation to the Dean of Studies or the Head, SQC-OR (T&P) Unit or the Class Teacher for such absence. If such explanation is found to be satisfactory by the Teachers’ Committee, then the percentage of attendance is determined disregarding the period for which explanation has been provided by the student and accepted by the Teachers’ Committee.
A student is also required to maintain satisfactory conduct as a necessary condition for taking semestral examination, for promotion and award of degree. Unsatisfactory conduct will include copying in examination, rowdyism, other breach of discipline of the Institute, unlawful / unethical behaviour and the like.
A student will be allowed to take a semestral examination in any course if he / she attends at least 75% of all classes of that course and his / her conduct is satisfactory.
For any semestral examination a student is declared to have passed the examination if he / she
NOTE: The term ‘score’ mentioned in the preceeding criteria for passing a semester will mean composite score or post backpaper score, as may be applicable.
A student is declared have failed the examination if he / she fails to pass the same.
There is a provision of backpaper examinations in all the courses, except Dissertation, Project - I and Project - II. If the composite score of a student falls short of 45% in a credit course, or 35% in a non-credit course, the student may take a backpaper examination to improve the score. A student is required to take a backpaper examination if the composite score is less than the pass-mark. At most one backpaper examination is allowed in a given course. The post-backpaper score in a course is equal to the maximum of backpaper examination score and composite score, subject to a maximum of 45% .
A student can take a maximum of 2 (two) backpaper examinations in any of the four semesters of the M.Tech.(QROR) programme subject to a ceiling of a maximum of 2 (two) in the first year and 2 (two) in the second year. However, a student may take more than the alloted quota of backpaper examinations in a given academic year and decide at the end of that academic year which of the backpaper examination score / scores should be disregarded for computation of the post-backpaper score / scores. Such communication must reach the Class Teacher, in writing.
If a student misses the mid-semestral or semestral examination due to medical or family emergency he/she may be allowed to take supplementary examination/ at the discretion of the Teachers’ Committee, on the basis of an adequately documented request from the student. The maximum a student can score in any supplementary examination is 60%.
A student admitted to the first year of the programme is allowed to attend the second semester of the programme if he / she passes the first semestral examinations, otherwise he / she has to discontinue the programme.
A student, who takes all the second semestral examinations, will be allowed to go for field training (Project work) otherwise he/she has to discontinue the programme.
A student who passes the second semestral examination and completes the field training (Project work) satisfactorily as certified by the supervisor is promoted to the third semester of the programme, otherwise, he/she has to discontinue the programme.
A student promoted to the third semester of the programme will be allowed to attend the fourth semester of the programme if he / she passes the third semestral examinations.
A student who submits his / her dissertation and project report within the prescribed time limit and passes the fourth semestral examinations and does not obtain less than 45% in dissertation and projects will be declared to have completed the fourth semester of the programme.
If even after the backpaper and supplementary examinations referred to in the preceeding paragraphs the student fails in the first or the second semesteral examinations, he/she has to discontinue the course. However, if he / she fails in the third or the fourth semestral examination even after the backpaper and supplementary examinations, then he / she may be allowed to repeat the second year of the course without stipend. The scores obtained during the repetition of the final year are taken as final scores in the final year. A student is given only one chance to repeat a programme. A student will be asked to discontinue if he / she fails in third or fourth semester of the repeating year.
A student who is asked to discontinue the programme is not eligible for readmission to this programme even through the admission test.
A student gets a degree if his/her conduct is satisfactory and he/she passes all the four semesters and is placed in the
A student passing the M.Tech.(QROR) degree examination is given a certificate of the degree and a mark-sheet mentioning.
The stipend rules for second, third and fourth semesters following the declaration of results of the preceeding semester is as follows:
Stipend can be restored because of improved performance and/or attendance, but no stipend is restored with retrospective effect.
TUITION FEE, STIPEND AND CAUTION DEPOSIT
All students other than those sponsored by the employers are awarded full stipend at the time of admission initially for the first semester only. The present rate of stipend is Rs.2500/- (Rupees two thousand five hundred only) per month. The students (other than those sponsored by the employers) are also eligible to receive a contingency grant of Rs.1500/- (Rupees one thousand five hundred only) per semester in reimbursement of cost of text books and supplementary text books, photostat copies of required academic materials, a scientific calculator and other required accessories for the practical classes. All such expenditure should first be approved by the respective class teachers. The payment of stipend and the reimbursement of contingency grant will, however, be governed by the following terms and conditions :
The contingency grant sanctioned will be treated as a limit and the student concerned will be reimbursed the actual expenditure incurred by him on the admissible items within the limit. The grant is not to be paid as an outright payment.
The books and nonconsumable items purchased or acquired out of the contingency grant allowed will be the property of the Institute and the student will have to return them at the end of the course.
The following terms and conditions will govern the grant of the stipend :
For sponsored candidates : Sponsored candidates, if admitted to the course, will not receive any stipend or contingency grant. Their sponsors will have to pay a tuition fee of Rs.20,000/- only per candidate per year as course fee and provide facilities for carrying out project work on practical problems during normal working hours under the guidance of the faculty of the Institute. In addition to the course fee, the sponsoring organisations will have to reimburse the travelling expenses of the members of the faculty to guide the project work of their nominees.
Each student, whether sponsored or not, will have to make a refundable deposit of Rs.1,000/- only as caution money for use of department equipment and facilities.
The Institute has many experienced and highly qualified personnel in SQC and OR. In addition to their research work, they actively participate in the teaching programmes of the Institute. Moreover, experts in the field are invited from professional and industrial organisations to deliver lectures on different topics of quality reliability and opetations research. Most of the faculty members also actively engage themselves in externally funded consultancy/project works on live problems of quality.
CLASS TEACHER
One of the faculty in a class is designated as the class-teacher. All students are required to meet their respective class-teacher periodically to get their academic performance reviewed and to discuss any academic problems if any.
Students are allowed to use the reading-room facilities in the library and are allowed access to the stacks. They have to pay Rs.250/- as security deposit in order to avail of the borrowing facility. At most four books can be borrowed at a time. Any book from the Text Book Library (TBL) may be issued to a student only for overnight or week-end provided at least two copies of that book are present in the TBL; only one book will be issued at a time to a student. Fine will be charged if any book is not returned by the due date stamped on the issue-slip. The library rules and otherdetails are posted in the library.
