Item Comparing the performance of neural networks developed by using Levenberg–Marquardt and Quasi-Newton with the gradient descent algorithm for modelling a multiple response grinding process(Elsevier, 2012-02) Routroy, SrikantaMonitoring and control of multiple process quality characteristics (responses) in grinding plays a critical role in precision parts manufacturing industries. Precise and accurate mathematical modelling of multiple response process behaviour holds the key for a better quality product with minimum variability in the process. Artificial neural network (ANN)-based nonlinear grinding process model using backpropagation weight adjustment algorithm (BPNN) is used extensively by researchers and practitioners. However, suitability and systematic approach to implement Levenberg–Marquardt (L–M) and Boyden, Fletcher, Goldfarb and Shanno (BFGS) update Quasi-Newton (Q-N) algorithm for modelling and control of grinding process is seldom explored. This paper provides L–M and BFGS algorithm-based BPNN models for grinding process, and verified their effectiveness by using a real life industrial situation. Based on the real life data, the performance of L–M and BFGS update Q-N are compared with an adaptive learning (A-L) and gradient descent algorithm-based BPNN model. The results clearly indicate that L–M and BFGS-based networks converge faster and can predict the nonlinear behaviour of multiple response grinding process with same level of accuracy as A-L based network.Item Antecedents and drivers for green supply chain management implementation in manufacturing environment(IUP, 2009) Routroy, SrikantaGreen Supply Chain Management (GSCM) is, today, gaining much importance in manufacturing environment due to pressure from the government and environmental consciousness among the customers, to gain competitive advantage. In this paper, an attempt has been made to propose the antecedents and drivers of GSCM in a manufacturing environment, followed by a detailed discussion. While the antecedents of GSCM implementation are proposed as top management support and government's initiatives, the drivers of GSCM implementation are proposed as green sourcing, Green Design (GD), green manufacturing and re-manufacturing, green packaging, Reverse Logistics (RL), Environmental Management System (EMS), green innovation and customer awareness. These proposed antecedents and drivers for GSCM implementation in the manufacturing environment are highly conceptual in nature, which may be validated empirically by conducting a survey among various manufacturing supply chains, for complete acceptability.Item Agriculture supply chain: A systematic review of literature and implications for future research(Emerald, 2017-11) Routroy, SrikantaThe purpose of this paper is to review the agriculture supply chain (ASC) literature along many dimensions which include but are not restricted to scope, objective, wastages, driver, obstacle, outcome, etc.Item Evaluating the critical success factors of supplier development: a case study(Emerald, 2013-05) Routroy, SrikantaThe purpose of this paper is to identify and evaluate the critical success factors (CSFs) responsible for supplier development (SD) in a manufacturing supply chain environment.Item A systematic literature review of healthcare supply chain and implications of future research(Emerald, 2019-10) Routroy, SrikantaThis paper aims to review the healthcare supply chain (HSC) literature along various areas and to find out the gap in it.Item Differential evolution algorithm for supply chain inventory planning(Emerald, 2005) Routroy, SrikantaThis paper discusses the inventory planning of a supply chain, which consists of a manufacturer, distributor and retailer.Item Agile manufacturing: a systematic review of literature and implications for future research(Emerald, 2017-10) Routroy, Srikanta; Potdar, Pavan KumarAgile manufacturing (AM) has evolved as a revolutionary way of manufacturing the products while managing the uncertainties, product introduction time, responsiveness, innovation, superior quality, etc. along the supply chain to satisfy the ever increasing customer demand and to maximize the profit.

The present work is the first comprehensive review on utilization of alternate materials, emphasizing hazardous industrial byproducts, as constituents of RSC. Such usage enhances the performance, sustainability, and affordability of RSC. Added advantages are the immobilization of wastes and the conservation of natural resources for RSC. The review analyses incorporation of ferrous and non-ferrous slags, mines wastes, plastics, red mud, cathode ray tube's glass, metallic wastes, fly ash, silica fume, and miscellaneous residues. Besides, utilization of fibers, nanoparticles, and calcined clay is investigated. The influence on shielding efficiency is adjudged by scrutinizing changes in parameters such as half-value layer and linear attenuation coefficients. Similarly, variations in mechanical and durability properties are investigated and compared. The underlying responsible factors related to the physical, chemical and morphological characteristics of materials and their consequences on RSC’s behavior are correlated. In association with alternatives, the advantages, disadvantages, and possible treatment methods are discussed. The country-wise, material-specific, and progressive research trends are revealed to facilitate future work in this upcoming field. Finally, conclusions are drawn with exposition of current bottlenecks and scope of future research.Item Analyzing the agile manufacturing barriers using fuzzy DEMATEL(Emerald, 2017-10) Routroy, Srikanta; Potdar, Pavan KumarThe purpose of this paper is to identify and analyze the agile manufacturing barriers (AMBs) for establishing a cause and effect relationship among them.Item Analyzing the supply chain risk issues for an Indian manufacturing company(Emerald, 2014-07) Routroy, SrikantaThe purpose of this paper is to identify, analyze, assess and manage the risks issues involved in an Indian manufacturing supply chain.

In today's markets, no business can be successful without mastering the issues, problems and possibilities in managing competitive supply chains. In competitive supply chain network, facilities location includes location of manufacturing plant, which is considered as supply chain design decisions and involved in major capital investments and has a long-term effect on the supply chain performance. Therefore, the successful execution of this decision would give cutting edge to the organization. Selection of a facilities location is a complex task as it involves both qualitative and quantitative factors. The present work describes a framework for selection of facilities location in competitive supply chain.Item Analyzing environment sustainability enablers using fuzzy DEMATEL for an Indian steel manufacturing company(Emerald, 2019-03) Routroy, SrikantaThe purpose of this paper is to analyze the Environmental Sustainability Enablers (ESEs) for an Indian steel manufacturing company to select the appropriate set of ESEs for implementing and enhancing environmental sustainability.Item Benchmarking model of supplier development for an Indian gear manufacturing company(Emerald, 2014-04) Routroy, SrikantaThe aim of this paper is to propose a benchmarking model of supplier development (SD) for an Indian gear manufacturing company for its successful adoption and improvement in a continuous basis.Item Framework for green procurement: a case study(Inder Science, 2012-06) Routroy, SrikantaManufacturing companies are putting significant effort and investment to achieve feasible and affordable greenness in their supply chains.

Sometime, slender supply chain is a result of extensive SD program at multiple stages of a value chain. The leaner the supply chain lesser the time to respond the market change and other uncertainty. The increasing uncertainty because of market dynamics creates the new panorama of visibility issue where the existence of proper visibility deliver a seamless operation in supply chain performance, but its absence create havoc in entire value chain. In presence of SD where the supply chain is leaner, the visibility is a significant governing issue which can produce all the disadvantages of SD, if not dealt properly. In this paper, an attempt is made to address the criteria and their orientations those govern the supply chain performance through visibility under the presence of a well-defined SD. An Interpretive Structural Modeling (ISM) method is used to get a structural framework in a case environment.
