Price and lead time differentiation, capacity strategy and market competition
(Taylor and Francis Ltd., 2016)
We study a duopoly market in which customers are heterogeneous, and can be segmented as price or time sensitive. Each firm tailors (differentiates) its products/services for the two customer classes solely based on guaranteed ...
A new formulation and benders decomposition for the multi-period maximal covering facility location problem with server uncertainty
(Elsevier, 2016)
Facility location problems reported in the literature generally assume the problem parameter values (like cost, budget, etc.) to be known with complete certainty, even if they change over time (as in multi-period versions). ...
Bandwidth packing problem with queueing delays: modelling and exact solution approach
(Springer New York LLC, 2016)
We present a more generalized model for the bandwidth packing problem with queuing delays under congestion than available in the extant literature. The problem, under Poison call arrivals and general service times, is set ...
Product differentiation and operations strategy in a capacitated environment
(2011-09-07)
We study a firm selling two products/services, which are differentiated solely in their prices and delivery
times, to two different customer segments in a capacitated environment. From a demand perspective,
when both ...
Efficient solution of a class of location-allocation problems with stochastic demand and congestion
(Elsevier Ltd, 2014)
We consider a class of location–allocation problems with immobile servers, stochastic demand and congestion that arises in several planning contexts: location of emergency medical clinics; preventive healthcare centers; ...

Managing Workforce at Superior Refinery Limited (SRL) (A)
(Indian Institute of Management Ahmedabad, 2010)
The case deals with the functional and behavioral issues faced by an oil refinery shift in-charge regarding workforce management. In addition to the refinery policy requirements the behavioral constrains become extremely ...
Balancing U-shaped assembly lines with resource dependent task times: a simulated annealing approach
(Elsevier, 2014)
The advent of Just-in-Time (JIT) and Group Technology philosophies has popularized U-shaped assembly lines, which help overcome many of the disadvantages, like line inflexibility, job monotony, large inventories, etc., ...
A cutting plane approach to combinatorial bandwidth packing problem with queuing delays
(Springer Verlag, 2017)
The combinatorial bandwidth packing problem (CBPP), arising in a telecommunication network with limited bandwidth, is defined as follows. Given a set of requests, each with its potential revenue, and each consisting of ...
Multiple allocation hub interdiction and protection problems: model formulations and solution approaches
(Elsevier, 2018-03-29)
In this paper, we present computationally efficient formulations for the multiple allocation hub interdiction and hub protection problems, which are bilevel and trilevel mixed integer linear programs, respectively. In the ...
