International Journal of Mechanical and Industrial Engineering

Selection of supplier is one of the most critical activities performed by the organizations because of its strategic importance. Over the years a number of quantitative approaches have been applied to supplier selection problems. The selection process is commonly based on their previous performance records, so the ranking determines which supplier will get their supply contract. However a survey on current evaluation methods shows that they are all less objective and lack accurate data processing. These evaluation criteria often conflict, however and it is frequently impossible to find a supplier that excels in all areas. In addition some of the ...

International Journal of Mechanical and Industrial Engineering

Cold Draw Welded (CDW) tubes find a wide array of applications in the automobile industry. Electric Resistance Welded (ERW) tubes are surface treated with certain chemicals to make them eligible for cold drawing. The surface treatment is a time consuming process. Efforts have been directed to eliminate it altogether or at least to reduce its cycle time. We have assiduously conducted certain trials to establish the nature and character of the surface treatment. With the knowledge thus generated, we have, in our capacity, attempted to analyze why surface treatment is sine qua non to cold draw.

Classification Of Textures With And Without Rotation Angles: A Daubechies Wavelet Based Approach, Shaikhji Zaid M, J B Jadhav, V N Kapadia

International Journal of Mechanical and Industrial Engineering

Textures play important roles in many image processing applications, since images of real objects often do not exhibit regions of uniform and smooth intensities, but variations of intensities with certain repeated structures or patterns, referred to as visual texture. The textural patterns or structures mainly result from the physical surface properties, such as roughness or oriented structured of a tactile quality. It is widely recognized that a visual texture, which can easily perceive, is very difficult to define. The difficulty results mainly from the fact that different people can define textures in applications dependent ways or with different perceptual motivations ...

Optimization Of Orthopaedic Drilling: A Taguchi Approach, Rupesh Kumar Pandey, S.S. Panda

International Journal of Mechanical and Industrial Engineering

Bone drilling is a common procedure to prepare an implant site during orthopaedic surgery. An increase in temperature during such a procedure can result in thermal ostenecrosis which may delay healing or reduce the stability of the fixation. Therefore it is important to minimize the thermal invasion of bone during drilling. The Taguchi method has been applied to investigate the optimal combination of drill diameter, feed rate and spindle speed in dry drilling of Polymethylmethacrylate (PMMA) for minimizing the temperature produced.

Guiding The Implementation Of Quality Improvement Projects: A Toc Approach, Papiya Bhowmik, Sujit Kumar Pattanayak, Shibamay Mitra Sep 2020

Guiding The Implementation Of Quality Improvement Projects: A Toc Approach, Papiya Bhowmik, Sujit Kumar Pattanayak, Shibamay Mitra

International Journal of Mechanical and Industrial Engineering

Many research has shown that approximately 70% of every medium to large scale industries have some type of quality improvement (QI) program. Depending on various independent studies, researchers have concluded that only onefifth of all QI projects show attractive output. The reason for this disappointing result is most of the QI programs are not result oriented. The main aim of this paper is to elaborate the value of using the Theory of Constraints (TOC), so that a result-oriented QI program can be achieved with a better bottom-line impact, which will be better than the traditional cost based selection process.

Inventory Control Using Abc And Hml Analysis – A Case Study On A Manufacturing Industry, Shibamay Mitra, Sujit Kumar Pattanayak, Papiya Bhowmik

International Journal of Mechanical and Industrial Engineering

Inherent uncertainties in demands and supply make it difficult for supply chains to achieve optimum inventory replenishment, resulting in loss of sales or keeping excessive inventories. An unkempt inventory can take up to one-third of an organization’s annual investment. Therefore, in order to compete with invariably erratic demands, it is not only challenging to develop an intelligent system to maintain and control an optimum level of inventory but has also become mandatory. Here we have tried to study the inventory control system of an EMU coach manufacturing industry using ABC and HML analysis method.
