Six Sigma (6σ) is a set of techniques and tools for process improvement. It seeks to improve the quality of the output from a process by identifying and removing the causes of defects and minimizing variability in manufacturing or the process. Some have found the Six Sigma methodology an excellent way to improve their processes as it uses statistical tools to measure processes in terms of defects and variation, transforming them into opportunities for business growth. The project would aim to examine the established piping installation process of a vessel construction, analyse the relevant data to reduce the variability and reduce the cycle time by reducing the rework. It would aim to focus on the existing quality process, analyse the data of acceptance of installed pipes as per QAP, use five established steps of six sigma to provide the requisite control measure for improving the productivity and reducing the cycle time in a vessel construction project. Consistency in achieving planned targets during vessel construction project requires timely availability of Inspection cleared pipes/spools for subsequent processes of Flushing, Leak test & Final Inspection before connecting them, with live engineering systems. The project would also measure the initial sigma level of the existing process and aim to conclude by providing recommended ways of reducing the rejection during quality inspection using established six sigma processes. This project would eventually aim to improve the production process and reduce the cycle time of the entire piping installation process.

The advent of globalization in the market has led to huge competition among the companies in various fields to achieve best supply chain practices. Increasing focus on environmental concerns has driven critical changes in industries’ strategy by incorporating sustainability in their supply chain. A supply chain which does not threaten the opportunities for future generations by considering environmental and social impact in addition to the economic impact leads to the concept of Sustainable Supply Chain Management (SSCM). Firms adopt sustainability by implementing specific practices - named as SSCM practices, in supply chain. However they struggle to identify the influential practices.This Paper intends to analyze the SSCM practices in plywood Industries in Visakhapatnam using Interpretive Structural Modeling (ISM). ISM method is used to develop a structural model to identify the influential practices. The SSCM practices are identified through literature review and from domain experts and managers of industries. Then practices are grouped under the dimensions of sustainability namely economic, environmental and social. And ISM model is built through which the most dominant practice among them in each dimension is identified.

The main focus of this work is to improve the strength, stiffness, wear resistance and fatigue strength of polyoxymethylene (POM). For this purpose, POM is incorporated with a lubricating additive polytetrafluoroethylene (PTFE) and reinforced with silanized multiwalled carbon nanotubes (CNTs). PTFE filled POM composites with varying weight fraction of PTFE and hybrid composites with 1 wt% silanized CNTs and varying weight fractions of PTFE were fabricated by melt compounding using a twin screw extruder followed by injection molding. Tensile, flexural, wear and fatigue behavior of the developed composites were evaluated. Incorporation of PTFE resulted in a significant decline of tensile properties, flexural properties and fatigue strength, whereas specific wear rate and coefficient of friction increased significantly. Reinforcing PTFE filled POM composites with 1 wt% functionalized CNTs has led to improvement of strength, stiffness, wear resistance and fatigue strength. Hybrid composites with 10 wt% PTFE and 1 wt% functionalized CNTs resulted in improvement of strength and stiffness by 31% and 50% respectively and decrease in wear rate and friction coefficient by 67% and 44% respectively as compared to pristine POM.

Fiber-reinforced polymer composites have played a dominant role for a longtime in a variety of applications for their high specific strength and modulus. The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only synthetic fibers such as glass, carbon etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. An attempt has been made to utilize the coir, as natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap. The present work describes the development and characterization of a new set of natural fiber based polyester composites consisting of coir as reinforcement and epoxy resin. Coir composites are developed and their mechanical properties are evaluated, at five different volume fractions and tests were carried out and the results were presented. Experimental results showed tensile, static and Dynamic properties of the composites are greatly influenced by increasing the percentage of reinforcement, and indicate coir can be used as potential reinforcing material for many structural and non-structural applications.
