A logarithmic goal programming approach to develop the utility function for a railway travel
(International Journal of Revenue Management, 2015)
Railway passengers are in a dilemma to choose the best train among several alternatives available in a particular route. A relative comparison of competing railways helps the passenger to make an informed choice before the ...
Lessons of success in OR/MS practice gained from experience in Indian and US steel plants
(2000-10-15)
I worked on modeling integrated steel plants in India (as an
analyst) and in the USA (as a doctoral student). The following
factors influence the success of OR/MS practice: positioning
the OR/MS team in operations, ...
An expanded database structure for a class of multi-period, stochastic mathematical programming models for process industries
(Elsevier, 2014)
We introduce a multiple scenario, multiple period, optimization-based decision support system (DSS) for strategic planning in a process industry. The DSS is based on a two stage stochastic linear program (SLP) with recourse ...
A logarithmic goal programming approach to develop the utility function for a railway travel
(Inderscience Enterprises Ltd., 2015)
Railway passengers are in a dilemma to choose the best train among several alternatives available in a particular route. A relative comparison of competing railways helps the passenger to make an informed choice before the ...
Capacity management of intensive care units in a multi- specialty hospital in India
(2010-07-22)
The paper describes the capacity management of Intensive Care Units (ICUs) in a 300- bed multi- specialty hospital where the alternative ICU is utilized when the appropriate ICU is full for a set of two types of ICUs. ...
Capacity management of intensive care units in a multi- specialty hospital in India
(2010-07-26)
The paper describes the capacity management of Intensive Care Units (ICUs) in a 300- bed multi- specialty hospital where the alternative ICU is utilized when the appropriate ICU is full for a set of two types of ICUs. ...
An optimization based decision support system for strategic and operational planning with in-process industries: case of pharmaceuticals industry in India
(2007-10-29)
We describe how a generic multi-period optimization-based decision support system (DSS) can be used for
strategic planning in process industries. The DSS is built on five fundamental elements—materials, facilities,
activities, ...
Mathematical modeling for demurrage reduction in coal transportation for an Indian thermal power plant
(Springer, 2004)
Competitive pressures on power plants have seen them attempting to reduce their
operating expenses for profitable operations. In India, the plants use wagons of the
Indian Railways to transport coal from the mines (in ...
New decision support system for strategic planning in process industries: computational results
(Elsevier, 2018-10)
The impact of a Stochastic Linear Programming (SLP) based Decision Support System in a manufacturing company, such as an integrated aluminum plant, is measured by two important parameters, the VSS and EVPI. With the real ...
A two-part dynamic pricing policy for household electricity consumption scheduling with minimized expenditure
(Elsevier, 2018-02-22)
In this paper we propose an optimization model for scheduling electrical appliances for an individual household. Here, customers are offered dynamic prices which are a function of that household’s planned consumption and ...
