P. Raghuram, Sahay, M., and .G.Saleeshya, P., “Delivery Service through an Integrated Inventory Management Model using a System Dynamics Model”, Proceedings of the International Conference on Industrial Engineering and Operations Management Bogota, Colombia, 2017.[Abstract] A pull production system is a make-to-order environment where manufacturing is started only after customer order is received and hence demand is confirmed. In an environment having dominant flow path for the products, it offers challenging scope for the management and control of raw material, work-in-process and finished goods inventory. Literature and industrial practice suggests a variety of heuristic models used to control inventory to optimal levels. Estimating and knowing the current and future inventories to be maintained is essential to sustain the material flow throughout the planning period. In this paper, we develop an integrated inventory control model integrating the demand and component material flows in a multi-customer, multi-product environment using system dynamics simulation modeling. We have simulated the model in a pull production system where the complete cycle depends on the customer order. The inventory level and structure are linked to delivery service and in effect to competitive advantage. More »» |

P. Raghuram and Dr. Saleeshya P.G., “Assessing the responsiveness of supply chain – structural equation modelling based approach”, International Journal of Logistics Systems and Management, vol. 25, pp. 558–579, 2016.[Abstract] Companies worldwide have now realised that ‘customer focus’ is what wins the game. As demands of the customer become more and more volatile and unpredictable, they have to stay ahead of their competitors in fulfilling the needs of the customer. The supply chain as a ‘unit’ has to compete against other supply chains for reaching out and delighting the customer. Responding fast to the changing customer needs has been an intangible factor underlying a successful business. Thus, responsiveness of the supply chain has become the differentiator between the competing supply chains. In this paper, the end-to-end supply chain factors influencing responsiveness are identified from extant literature and a model of responsiveness of the supply chain has been developed by conducting a survey of 204 pump manufacturers. The developed model has been validated through confirmatory factor analysis using structural equation modelling. These findings can help to identify the areas of improvement for the supply chain and may lead to a focused improvement in these areas thus improving responsiveness and profitability. More »» |

P. Raghuram, Balaji, K., Karthik S, Hari Haran R, Siva Sankar P, and Vimal P, “Optimization of Machining Parameters In Turning Process Using Exergy Analysis”, International Journal of Applied Engineering Research, vol. 10, pp. 29907-29916., 2015.[Abstract] This study uses thermodynamic frame work to conceptualize the energy used in a manufacturing process. High amount of energy consumed per unit material removed in traditional process has formed the base for developing new technologies while, optimizing the traditional method is often neglected. The main focus has been on product quality while the efficiency of energy per material removal has taken a back step. The study covers turning operation and characterizes the energy consumption by varying the machining parameters. With a steep increase in energy prices, a major part of machining cost is due to the energy consumed. Therefore we take this opportunity to perform exergy analysis to identify conditions where resources are lost and thereby arrive at optimum conditions where the process can run at higher efficiency and reduced cost.

S. Sarath, P. Raghuram, and Venkateswaran, R., “Optimization and scheduling of HAZCHEM logistics with time windows : A case study”, International Journal of Applied Engineering Research, vol. 10, pp. 34270-34276, 2015.[Abstract] This research addresses the optimization of Total Logistics Cost (TLC) and time incurred in logistics activity of the transportation of a liquid Hazardous Chemical (HAZCHEM) through road. The logistics of HAZCHEM is receiving considerable attention because of the increase in demand for various industries and the means of transport is also an important factor. In this paper, the total logistics activity for an industrial system is taken by considering the unloading of the chemical from the ship to the storage tank and the transportation from the storage tank to two different manufacturing plants through roadways. The problems faced are low rate of transportation of raw material and high cost of storage and transportation which affects the production rate and hence profit. The decision variables examined are the number and location of manufacturing plants in the logistics system, the flow of materials from storage to manufacturing plants, the quantity to be transported from storage terminal to plants, loading and unloading of raw materials, storage of raw materials, scheduling of trucks, transportation costs and maximizing fill rate. We are proposing a multi objective optimization model, considering all the constraints. The developed model is a MILP function. The model is solved using Lindo which uses simplex algorithm and Solver in Excel using Evolutionary GA to compare the optimality. The result indicates that the developed model produces considerable reduction in the total system wide logistics cost. We are considering the case of a chemical manufacturing plant which uses liquid HAZCHEM as a basic raw material. © Research India Publications. More »» |

H., Vignesh, M., and Ranjith, S., “Remaining life assessment of boiler components”, International Journal of Applied Engineering Research, vol. 10, pp. 23755-23768, 2015.[Abstract] Super heater and re-heater coil failures occur very often and thus the boiler have to be shut down affecting power generation. Pre-assessment of the component helps to plan procurement and replacement activities in advance and also improves the reliability and availability of the plant by reducing unplanned forced outages. This paper analyses the cause for such failures, the details of pattern of failure, material specification, operating parameters and the mechanisms involved for the degradation. It looks at using the degradation in mechanical properties and the microstructure of the component as the guiding tools for predicting the health and the remaining life of the component. This paper paves way to assess the condition of any component of any industry. In this paper two different samples at different exposure limits have been considered and analyzed extensively. © Research India Publications. More »» |

Dr. Saleeshya P.G., P. Raghuram, and N Vamsi, “Lean manufacturing practices in textile industries–a case study”, International Journal of Collaborative Enterprise (IJCol. Ent), vol. 3, no. 1, pp. 18–37, 2012.[Abstract] Lean manufacturing is a philosophy of eliminating waste through continuous improvement. This paper is an outcome of a case study conducted in a textile industry in south India. Though the concept of lean manufacturing has shown good results in continuous process industry, it has not been extensively used as compared to discrete manufacturing industries. Process industries, especially textile industries, have automatic machinery which are highly inflexible and have high volume/low variety products. This nature of the textile industry makes implementing lean manufacturing techniques a challenge; hence implementing lean techniques in a textile industry has been taken up as a challenge. We have chosen a combination of value stream mapping (VSM), 5S, kanban, kaizen, poka-yoke, and visual controls to improve the processes. The achievement potential scores before and after lean implementation has been highlighted using radar diagrams. The findings of this study reveal that a thorough analysis of the process, setup, and changeover time (CO), use of colour coding for identification of volume-mix, use of kaizen and quality circles which empower the workforce, are some of the various keys to a successful lean implementation in a textile industry.

Dr. Saleeshya P.G., Karthik Suresh Thampy, and P. Raghuram, “A combined AHP and ISM-based model to assess the agility of supply chain-a case study”, International Journal of Integrated Supply Management (IJISM), vol. 7, pp. 167-191, 2012.[Abstract] An agile supply chain corresponds to the quick responsiveness of an organisation to ever changing market demands without compromising on cost and quality of the product. The textile industry is one such industry having a volatile market demand. This paper is an outcome of a case study conducted in a leading spinning industry in South India. Various enablers and determinants of agility were identified through literature review, field study and industry study. Based on the findings of these studies a multi-level model was developed and the suitability of this model to improve the agility of supply chain was tested. For this, two methodologies - analytical hierarchy process (AHP) and interpretive structural modelling (ISM) were identified as suitable tools. The analysis of the results of AHP and ISM methodologies provide the industry an insight on how the supply chain can be made more agile. Further, the model provides the top management a clear vision of the practices to be implemented and the improvement methods to be adopted by the company for an effective management of supply chains in spinning industries.
