Achieving Supply Chain Coordination Through Lot Size Based Discount
(Elsevier, 2015) Routroy, Srikanta
A generic mathematical model is developed for a two level supply chain through lot size based discount to achieve supply chain coordination. The model considers a single product with probabilistic demand. It accounts total supply chain cost which entails product cost, inventory holding cost, ordering cost and stock-out cost considering the maximum allowable supply chain inventory. Genetic algorithm is used for determining the optimum levels of ordering quantity, supply chain savings, and discount percentage (i.e. an upper member should offer to a lower member of the supply chain) to enhance supply chain profit. A case situation is elucidated to demonstrate the salient features of the proposed model.
Addressing the Agile Manufacturing Impediments using Interpretive Structural Modeling
(Elsevier, 2017) Routroy, Srikanta; Potdar, Pavan Kumar
Agile manufacturing (AM) has achieved tremendous remembrance by the organizations to beat the uncertainties resulting from rapidly change market, shortening product life cycle, varying customer demand and obsolete technologies. AM is adopted as a new concept to improve the competitiveness of different organizations ranging from manufacturing sector to service sector. However, in reality, many organizations have been facing lots of problems during the implementation of AM due to some environment specific impediments. The AM implementation process is getting delayed without the efforts of addressing the root cause of Agile Manufacturing Impediments (AMIs). These AMIs have its deep roots along various tangible and intangible issues of the organizations. Therefore, an organization needs to target the appropriate AMIs as putting efforts on all AMIs is not feasible. In this paper, a methodology is proposed using Interpretive Structural Modeling (ISM) integrated with Fuzzy Matriced Impacts Croises Multiplication Appliqueeaun Classement (FMICMAC) algorithm for systematic analysis of impediments of AM. To demonstrate its practicality, a case study was conducted in an Indian automobile manufacturing company.
Addressing the Root Cause Impediments for Supplier Development in Manufacturing Environment
(Elsevier, 2014) Routroy, Srikanta
The manufacturing supply chains, designed for delivering the best to the customer should operate by following systems approach, where planning and execution are strategically carried out protecting the interests of each stakeholder. Supplier Development (SD) is one such sourcing strategy that a manufacturing company devise to strengthen its critical but fragile supply base, portraying mutual interests in the formulation. However in reality, many companies even though capable enough in conceiving and materializing their SD strategies yet, are miserably falling short off due to tremendous misdirected flow of resources. Often, the bitter experiences from the results due to misdirected SD efforts, the companies are pushed to draw wrong conclusions and inevitably search for other misdirected efforts without addressing the root cause impediments. In concrete, the misdirection in SD has its deep roots along various tangible and intangible issues of the operation field. Therefore, a manufacturer needs to bring these issues to the surface, critically analyze and uproot them for smooth development of its supply base strength. In this paper, a methodology is proposed using Interpretive Structural Modeling (ISM) - Fuzzy Matriced Impacts Croises Multiplication Appliqueeaun Classement (FMICMAC) algorithm for systematic analysis of impediments of SD. To demonstrate its utility, a case study was conducted in an Indian manufacturing company and the proposed methodology is applied to it in order to explain the salient features of the concept.

Analysis of Agility Performance of Supply Chain: A Case Study on Indian Automotive Manufacturer
(IOP, 2018) Routroy, Srikanta
Manufacturing companies should understand the changing customer needs and expectations, access and defend the competitive pressure, anticipate and manage the uncertain demand and supply chain risk, and implement the appropriate technology to survive and excel in today's marketplace. Therefore, they are moving away from mass production (i.e. lean supply chain) to one based on fast-responsiveness and flexibility, capitalizing on the rapid advancement in internet technologies and factory-on-demand mode of production (i.e. agile supply chain). It is observed that manufacturing companies in India in general and automotive supply chain in specific are compelled to cultivate supply chain agility for enhancing its performance level on continuous basis and comparing its supply chain agility performance with competitors to survive and sustain in the competitive business environment. Therefore, a methodology is proposed to evaluate the supply chain agility of a manufacturing supply chain and compare its performance level with competitors using Fuzzy Analytic Hierarchy Process and Taguchi Loss Function. A case study is developed and the proposed methodology is applied to Indian automotive supply chain for explaining the salient features of it.
Analysis of Critical Success Factors to Design E-waste Collection Policy in India: A Fuzzy DEMATEL Approach
(Springer, 2021-09) Dasgupta, Mani Sankar; Routroy, Srikanta
The design of an e-waste collection policy is challenging, especially for a country like India, where the economy is a developing state, and there is a large diversity in socio-economic factors. The e-waste collection policy impacts the various stakeholders such as the manufacturer, the raw material producers, the assemblers, the retailers, the generator (households and bulk consumers), the scrap dealers, the smelters, the recyclers, and the regulators. The design of an e-waste collection policy needs to consider the appropriate set of Critical Success Factors (CSFs), which will maximise the e-waste collection providing business sustainability to the stakeholders while satisfying the environmental regulations in the operating locations. Twenty-three CSFs identified and categorised in six implication dimensions for the e-waste collection policy framework based on a literature survey and experts committee view. The fuzzy DEMATEL approach is employed to analyse the CSFs to design an e-waste collection policy in India from a comprehensive perspective. Cause and effect interrelationship is established among the CSFs, and also their impacts are evaluated to segregate the CSFs into cause group (prominent influencing and independent) and effect group (influenced and dependent). The CSFs such as technology involvement, green practices, environmental program, certification and licensing, public ethics and stakeholder's awareness for circular economy are prominent influencing CSFs for e-waste collection policy in India. The current study is expected to provide a platform for policymakers to design the e-waste collection policy.

Analysis of post-harvest supply chain impediments for rural employability and waste reduction
(Inder Science, 2022-03) Routroy, Srikanta; Garg, Girish Kant
The tremendous amount of economic losses, welfare losses and distress among the farmers due to produce spoilage and quality losses are a few major concerns in the Indian post-harvest supply chain (PHSC). A study for identifying and analysing the impediments in the post-harvest supply chain was performed to minimise them. The interpretive structural modelling (ISM) was applied on the identified impediments to analyse the interactions among them and matrix cross-reference multiplication applied to a classification (MICMAC) analysis was used to categorise the impediments into four clusters on the basis of driving and dependence power. The key impediments obtained from the analyses are lack of government support, lack of transportation infrastructure and lack of fixation of minimum support price. And their revisions are to be improved with time to improve farmer profitability, rural employability and waste reduction. These impediments appear at the bottom in structural analysis thus hold a prime value among the identified impediments. The utility of this study is stated in the practical implications section, i.e., adaption of value addition practices for onion to reduce the spoilage ratio.

Analysis of suppliers' preferences to a manufacturer using Kano model and performance value analysis
(Inder Science, 2016-12) Routroy, Srikanta
The approaches to achieve competitive advantages have not been actively extended along the manufacturing supply chains, as most of them are practiced in competitively putting efforts to achieve the customer satisfaction alone. Conventionally, the suppliers' outlook has been mostly ignored by the supply chains without imparting the essential emphasis what it aptly deserves. Moreover, majority of the manufacturers along the supply chains have feeble supply bases and are seriously struggling to put forth a healthy competition. This is due to negligence in accounting the extraneous influence of supplier satisfaction construct which can eventually position a manufacturer as a preferred customer. Considering the above discussed issues, there are no specific studies available in the published literature to systematically capture, plan and manage supplier's perceptions, expectations and attractions which lead to supplier satisfaction. Thus, the current study is an attempt to resolute through an approach using Kano model and performance value analysis.
Analysis of supply chain vulnerability factors in manufacturing enterprises: a fuzzy DEMATEL approach
(Taylor & Francis, 2022-06) Sharma, Satyendra Kumar; Routroy, Srikanta
With an increase in supply chain disruptions, managing supply chain vulnerability has become a key factor to build resilient supply chains. Although supply chain vulnerability and associated factors are mostly studied individually or with selected groups, the supply chain literature lacks comprehensive and systematic studies. The current study aims to identify and segregate the supply chain vulnerability factors for manufacturing enterprises based on causal–effect relationships that exist between them. The supply chain vulnerability factors are identified from the extant literature review. Its applicability in Indian manufacturing enterprises is discussed with experts drawn from industry and academia. The cause–effect relationships of selected supply chain vulnerability factors are analysed using the fuzzy Decision Making Trial and Evaluation Laboratory (DEMATEL) approach. The obtained results indicate that supply design and supply chain efficiency-related factors are effect factors, whereas supply chain collaboration and information technology-related factors are causal factors. Complexity, centralisation, supplier concentration and low-cost sourcing are found to be the most prominent factors. This research contributes to the literature on supply chain vulnerability by describing the causal relationships among key factors impacting it. It would help managers to develop appropriate disruptions mitigation strategy(s) to make a resilient and robust supply chain.
Analyzing a manufacturer’s returns from supplier development programs
(Elsevier, 2017) Routroy, Srikanta
Supplier Development Programs (SDPs) have become the best modes for the manufacturers to improve their suppliers’ overall capabilities. The SDPs are used to transcend and advance the manufacturer-supplier relationships into strategic and sustainable working relationships. They are also proven to be the potential ones in developing the innovative and competitive supply sources in the value addition process. However, there must be a testing procedure for a manufacturer to know whether or not its SDPs are providing the intended returns. In this regard, several Supplier Development Outcomes (SDOs) specifically under a manufacturer’s interest have been identified. They are further analyzed against the SDPs of a manufacturer using Kano quality model integrated with performance value analysis. The said testing procedure was tried in an Indian electronic manufacturing company and the obtained results are demonstrated in this paper as a case study. The proposed procedure was proven to be beneficial to a manufacturer in knowing the efficacies of its SDPs and accordingly examine the influences acting on the SDPs.
