Tiru Arthanari has a B.Sc. (Statistics) with first rank from the University of Madras, a Master’s degree in Statistics, M.Stat., a Diploma in O.R., and a Ph.D. all from the Indian statistical Institute (ISI, Calcutta), a premier institute of higher learning and research in the fields of quantitative methods and their applications. Tiru has served as the Head of the SQC & OR division of ISI, which provides training and consultation to industries through its 11 units spread all over India. The Quality Mission Project of the division was launched during that period with a major grant (equivalent to NZ$ 3 million) from the government of India. Tiru is a very successful quality and optimisation consultant with sound theoretical basis and vast applied experience. He is a trained quality system auditor. Before migrating to New Zealand, Tiru was serving one of the three centres of ISI located at Bangalore, India as its head.

Pedigree Polytope and Traveling Salesman Problem
Traveling salesman problen is one of the difficult combinatorial problems. In this research I study an alternative combinatorial object called Pedigrees which I invented. My research students along with me have studied the properties of the set of pedigrees
