We propose inventory model assuming replenishment cost is to be linearly dependent on lot size and purchasing cost per unit item is dependent on lead time. Lead time is taken as decision variable. Shortages are allowed to backlog and to lose partly. Our objective is to cumulatively evaluate optimal replenishment lot-size, order time and lead-time for maximization of total profit. Considering the complexities of the proposed model, we propose a heuristic solution approach by developing an ERCM Genetic Algorithm based on ranking section, elitism, whole arithmetic crossover and non-uniform mutation dependent on the age of the population.

Choosing a proper integrated manufacturing technology is the most difficult and time consuming act for enterprises. Again, Planning plays a crucial role in embedding sustainability into the day to day operations and businesses maintain a strong focus on factors that have a clear and direct effect on their economic performance like cost of materials, profit etc. Electro-Discharge Machining (EDM) is a thermoelectric energy based non-traditional machining processes with Material Removal Rate (MRR), Overcut and Surface Roughness as important outputs. People working on EDM have used a number of ways to optimize them. The objectives being more efficient material removal coupled with reduction in overcut and improved surface quality. In this study the same are individually and simultaneously optimized using Taguchi method on EN41 material and the best combination of the input parameters were identified. Results are validated to show its efficacy in using these in different manufacturing shop floors

Successful cold chain management is essential for pharmaceutical companies, transportation providers and health care practitioners. With growing population and their demand; especially in retail and pharmaceutical sectors drives Indian cold chain market and it has huge potential to grow in the near future. India's greatest need is for an effective and economically viable cold chain solution that will integrate the supply chains for all commodities from the production centers to the consumption centers; thereby reducing physical waste and loss of value of perishable commodities. This article highlights the importance of cold chain concepts with Indian business scenario. Strategic planning of cold supply chain and their real value...

Non-conventional machining helps to sustain industries in this challenging environment. Electric discharge machining is one such precision machining that can produce complex product with great accuracy. This machine can be utilized in the manufacturing of complicated shaped die for plastic molding, automobile parts, aerospace, and other applications. In solving real-world problems like engineering design, business planning, and network design, challenges are being faced due to highly non-linear data and limited resources like time and money. Optimization is the best choice to solve such practical problems efficiently. This chapter deals with the optimization of EDM process parameters using two different bio-inspired optimization algorithms, namely, artificial bee colony algorithm and whale optimization ...

Design / Methodology / Approach: This paper proposes a hypothesis model within the decision-making framework that offers strategic alliance tool for managers in the area of supply chain to operationalize business decisions. Samples of more than 210 primary data sets are collected from population of different industries in India by a proper sampling method and by framing questionnaires. The relationship, as proposed in the hypothesis model, is assessed empirically by using statistical techniques called Structural Equation Modeling. Results: Practitioners may expect improved supply chain performance through strategic alliance between information intensive services and supply chain integr...

Further, an attempt has been made to develop the fundamental psychological mechanism of the aforementioned relationship by proposing retention (RE) as mediator.Design/methodology/approachFor this study, the required population on both private and public sector professionals of middle and senior-level management from service and manufacturing organizations functioning in various parts of India has been considered. For data collection, a complete set of questionnaires has been prepared and collected from 238 professionals. To study and test the hypotheses, structural equation modeling has also been used.Findingsa complete study on the data collected, it has been found that HC is significantly related with OP of the prospective professionals and RE has subsequently mediated the aforementioned linkage partially.Practical implicationsThe present study can suggest prac...

Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight expl...

Rather than becoming function-oriented, firms are now selectively deploying valuable resources on automated processes operated through technology-enabled ‘information communication’ platforms to improve performance. However, there are visible gaps in integrating business processes with information-enabled domain like enterprise resource planning (ERP), which has the potential to bring in the radical improvement in firm’s performance. Again, integration always does not come with positive results, specifically to Indian capital goods sector. Under this consideration, an attempt has been made to explore this unknown domain with conceptualization of a hypothesized model. Data for validation of this study were collected through questionnaire from 25 different units under Indian capital goods industry and relationship proposed in the hypothesized framewo...
