Bodhibrata Nag and Ashok Banerjee, "On a few strategies for a sustainable turnaround of the Indian Railways", Journal of Institute of Public Enterprise (2016) Volume 39, Issue 1 & 2, Page 16-36. Available at The paper focuses on evaluation of the few turn around strategies available with the Indian Railways to improve its operating ratio. The strategies examined are (a) choice of electric traction and the pace of electrification (b) improvement of utilization of network capacity (c) bench marking of maintenance expenses (d) bench marking staff deployment and (e) inflation indexed tariff. The paper demonstrates that judicious application of these strategies can have substantial impact on the profit margin of the Indian Railways. Bodhibrata Nag,"Combating Corruption in Indian Public Procurement- some exploratory case studies", Journal of Institute of Public Enterprise (2015) Volume 38, Issue 1 & 2, Page 1-34.Available at This paper has adopted the exploratory case study method of analyzing a few recent cases of public procurement irregularities documented by the vigilance departments and the CAG available in public domain to inquire into the following issues :(a) how do irregularities and instances of corruption persist in spite of safeguards and thereby find the deficiencies of the current procurement processes and control mechanisms, (b) recommending appropriate corruption prevention methods for arresting the deficiencies in the Indian context. The recommendations following the case analyses are the need for comprehensive set of measures including strengthening the accountability, monitoring and whistleblower mechanisms, training of procurement officials and building a strong information system. Bodhibrata Nag, "A MIP model for scheduling India's General Elections and Police movement", OPSEARCH(Springer) (Oct–Dec 2014) 51(4):562–576. DOI Conducting the General Elections for the 543 members of the Parliament of India across the 833 thousand polling stations spread over the 35 States is a mammoth exercise. Deployment of the Central Police Forces is essential to complement the role of the State police during the elections. However paucity of Central Police Forces necessitates the conduct of elections over stages. This paper proposes and demonstrates a MIP model to (a) schedule the elections with a minimum number of stages (b) sourcing the appropriate number of security personnel from the most convenient Central Police Forces bases (c)scheduling movement of security personnel between stages with the objective of minimizing men-miles. Bodhibrata Nag, "Public Procurement- case study of the Indian Railways", Journal of Institute of Public Enterprise (2013) Volume 36, Issue 1 & 2, Page 45-70. Indian Railways is one of the world’s largest public sector organizations. Its network, traffic, organization and extent of vertical integration are gigantic. This paper undertakes a critical examination of its procurement process to understand the procedures and institutional mechanisms which have evolved over time for safeguarding institutional interests. The paper examines issues such as organizational structure, procurement organization, source selection methodology, procurement oversight and regulation and their impact on the economy, efficiency, transparency and accountability aspects of procurement. It is found that a unique combination of internal vigil, external oversight by independent bodies and organizational characteristics contribute to robust procurement processes. Bodhibrata Nag, "A Dynamic Programming Algorithm for Optimal Design of Tidal Power Plants", Journal of The Institution of Engineers (India): Series B(Springer)(2013) Volume 94, Issue 1, Page 43-51. DOI Awarded the "The Union Ministry of Energy-Department of Power Prize" for the best paper published on Power Development and Utilization at the 29th Indian Engineering Congress 2014. A dynamic programming algorithm is proposed and demonstrated on a test case to determine the optimum operating schedule of a barrage tidal power plant to maximize the energy generation over a tidal cycle. Since consecutive sets of high and low tides can be predicted accurately for any tidal power plant site, this algorithm can be used to calculate the annual energy generation for different technical configurations of the plant. Thus an optimal choice of a tidal power plant design can be made from amongst different design configurations yielding the least cost of energy generation. Since this algorithm determines the optimal time of operation of sluice gate opening and turbine gates opening to maximize energy generation over a tidal cycle, it can also be used to obtain the annual schedule of operation of a tidal power plant and the minute-to-minute energy generation, for dissemination amongst power distribution utilities. Bodhibrata Nag and Katta G.Murty, "Organizing National Elections in India to Elect the 543 Members of the Lok Sabha", Algorithmic Operations Research 7(2013): 55–70. Available at & There are 833 thousand polling stations in all of the 543 parliamentary constituencies spread over 35 states of India. On the day elections are being held in any one of these polling stations, a minimum of 4 Central Police Force(CPF) personnel must be deployed there, to maintain law and order and guarantee that voters can vote freely without being intimidated by anyone. As the number of CPF personnel available for this activity is limited, it is not possible to hold the Indian General elections on a single day over the whole country. So the set of 35 States of India is partitioned into a number of subsets, with elections in each subset of states being held on a single day. This partition is required to satisfy the constraints that the states in each subset are contiguous, and the subsets themselves must be contiguous. We present a method for organizing the Indian General Elections subject to these constraints, and minimizing the total number of election days required, and the total cost for the movement of CPF personnel involved. The method is based on the shortest Hamiltonian path problem, a tour segmentation problem defined in the paper, and the bipartite minimum cost flow problem.

Available at & A large number of railway mega-projects are planned or are under implementation for capacity augmentation, for serving the needs of trade, specific regions or industry sectors. Since transport capacity is one of the main levers of economic progress, it is essential that augmentation of transport capacity is not held up. It is therefore essential to choose the appropriate project management structure, project financing, land acquisition and contractual process to ensure design, construction and commissioning of projects without cost and time overruns. These choices have to be made keeping in view the context of the organisational technical capacity, financial capability, contractor capacity, and industry and trade growth pattern. This paper examines the various project management structures, methods of project financing, land acquisition and contractual processes along with their advantages and disadvantages. The paper takes the specific case of the Dedicated Freight Corridor project to examine the appropriateness of options. Bodhibrata Nag and Katta G. Murty, "Diesel locomotive fueling problem (LFP) in railroad operations", 49 OPSEARCH(Springer)(2012):315–333. DOI About 75 % of the world’s railroads operate with diesel fuel. Even though European railroads rely on electric traction to a large extent, US railroads rely mostly on diesel fuel (100 % of US freight is hauled by diesel locomotives). Like in other industries there is intense competition to keep costs low; and in railroad operations based on diesel locomotives, the cost of fuel and its delivery is the major component of the overall cost. Since the cost of fuel is highly location dependent (due to local taxes and transportation costs between supply and demand points), locomotive fueling problem discussed in this paper is a critical problem in railroad operations. Given: the set of yards, the set of trains to operate, the locomotive assignments to trains, and the fuel cost and capacity data; this problem deals with finding the fueling plan for the various trains to minimize the total cost of fueling the locomotives. We describe three different algorithms, two based on greedy method and one using MIP model, that we used to solve this problem and highlight the summary of solutions obtained by each of them for comparisons of these algorithms.
Papers in Peer-reviewed Conference Proceedings: Bodhibrata Nag(2013).Heavy Haul Corridor Selection and Service Design Models in Proceedings of 10th Heavy Haul International Conference,February 2013, New Delhi. Available at SSRN: Heavy haul corridors are capital intensive and are relatively expensive to maintain. It is therefore imperative that heavy haul corridors are chosen with care, such that sufficient traffic is available on the corridors to ensure adequate returns. The strategic choice will be dictated by projected pattern and volume of freight traffic, projected pattern of passenger traffic and terminal facilities. Various choices may be obtained with different rolling stock and locomotive capacity to obtain scenarios with existing and future fleet characteristics, as well as future terminal facilities. Further, tactical operating plans for networks with heavy haul corridors should be designed properly to ensure maximum utilization of such corridors with a given set of customer demands, rolling stock and locomotive size and capacity, terminal facilities and capacity of peripheral networks. Such operating plans which might span from a fortnight to three months, include decisions regarding routes, frequency of services, aggregation and disaggregation policies, empties repositioning policies and direct or consolidating train service policies. These operating plans may also depend on the service level committed to a customer, which is again tied to a particular pricing. This paper proposes two operations research based models: (i) a model for choosing a heavy haul corridor(s) within an existing network and (ii) a model for design of an optimal operating plan for an existing network with a designated heavy haul corridor(s). The models are further demonstrated on a hypothetical railroad network with test data. Bodhibrata Nag and Jeetendra Singh(2012).A multi-criteria approach for railway project portfolio selection in Proceedings of 10th International Conference on Transportation Planning & Implementation Methodologies for Developing Countries, December 2012, Mumbai. Available at SSRN: In an emerging economy, transport planners have a difficult task of allocating scarce and costly capital amongst the available shelf of railway projects to effectively meet the increasing demands for railway infrastructure. Hitherto, a single criterion such as IRR was being used for ranking and selection of railway projects; however of late, planners have realized the need to incorporate other economic and strategic criteria too in project portfolio selection. There is thus now a need for an analytical tool to assist the decision makers in systematically evaluating the options for optimal allocation of capital amongst railway projects, using various criteria simultaneously. This paper proposes a two-phase analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal solution (TOPSIS)-Global Criteria approach for the purpose, wherein AHP is used to determine the weights of each criterion based on the planners’ evaluation of their relative importance. A single objective function is then obtained using TOPSIS-Global Criteria approach, which is used to identify the optimal capital allocation amongst competing projects. The methodology is demonstrated on a test case of a shelf of railway projects to obtain the best project portfolio fund allocation within the available capital resources.

Bodhibrata Nag, "Determinants of Profitability of US Class I Freight Railroads", Business Expert Press 978-1-94744-161-3 (2017) Expert Insights Bodhibrata Nag and Ashok Banerjee, "Airport Express Metro Line: The Turnaround Story", IIM Calcutta Case Research Centre, 2017 The case highlights how a public sector undertaking operationally turned around an entity run by a private operator. The learning from the case is contrary to the popular belief that private sector generally operates more efficiently than public sector. The case also shows the importance of framing of Concession Agreement and how a poorly drafted agreement can lead to disastrous results. The case describes DMRC ’s successful execution of metro project in New Delhi, India, and its experience of using public-private partnership for construction and operation of the Airport Express Metro Line (AEML). The case is intended for use in courses on Project Management, Risk Management, Project Finance, and Public Private Partnership. The case starts with its protagonist grappling with the situation following the abandonment of the project by its private partner (Reliance - CAF), and ends with its protagonist looking for further ways and means to rescue the project. The case provides a brief description of Delhi Metro project executed and operated by DMRC. The case describes the genesis of Airport Express Metro Line along with its unique public-private partnership financing structure. The construction and operations travails of the Airport Express Metro Line are then elaborated upon, further to which the project was abandoned by its private partner. The final part of the case deals with the efforts of public sector organization DMRC to make the service financially viable against many odds under which the project had been taken over after abandonment. Bodhibrata Nag, "Regulation and Competition of US Railways", Rail Business, Vol 7, Issue 35, July 2016. Bodhibrata Nag and Ashok Banerjee, "Indian Railways: in quest of a sustainable turn-around", IIM Calcutta Case Research Centre, 2014 The case focuses on evaluating the various turn around strategies available to the Indian Railways to improve its profit margin or operating ratio in railway industry parlance. Though Indian Railways is a government body,it is required to function as a commercial enterprise. It receives no budgetary support for its revenue expenses. It does receive some budgetary support for its capital expenditure, but has to pay dividends on the capital received until perpetuity. However, it does not have the freedom to decide on the pricing of transport products, the remuneration of its employees or close down services on un-remunerative sections of the network. It has to contend with powerful employee unions and demands of the populace and industry for more services and higher levels of service. This case is a typical illustration of demands made on public sector organizations operating in developing countries. The lessons derived from this case could well be applied to private sector enterprises operating in highly competitive environments, where the market forces decide the pricing. The case is intended for use in courses on costing and strategic management. The case could also be used for demonstrating the inherent problems of managing a public sector enterprise in a democratic country in a public systems course or searching for evidences of Leibenstein's X inefficiency concept in monopolies in an economics course.

Murty, Bodhibrata Nag, and Omkar D. Palsule-Desai, "Freight Transport by Rail" While the freight railroad industry has been in existence for about 200 years, the procedure used for combining freight rail-cars into blocks based on their destination yards (also referred to as nodes in this chapter) and other attributes, and then assembling blocks into trains has essentially remained the same. Based on customer orders on hand for transporting goods wagons; and the origin, destination, and other attributes like physical dimensions, freight type etc., the railway generates a trip plan detailing the movement of each rail-car from its origin yard to its specified destination yard. The main components of the trip plan are: (a) how to combine the rail-cars at each rail yard into groups called blocks, this is known as the block design problem, (b) designing trains to operate; identifying the origin, destination, route for each individual train, and along the route what blocks to pick up, drop off at different yards along the route; this is known as the “Block-to-train assignment (BTA) and train routing” problem, and also referred to as the Train Design Problem. In this chapter we discuss this train design problem only assuming that blocks have already been formed at each of the yards; and the data on the origin, destination, number of rail-cars, length, tonnage of each block to be transported is given. This is a difficult combinatorial optimization problem encountered in the railroad industry. Bodhibrata Nag and Katta G.
