This is an easy to understand presentation on how organizations can procure greener products in order to lower the environmental impacts throughout the value chain. This presentation was made by our chairperson Dr. Prasad Modak at the CII GreenCo Forum held in Mumbai on 27th January 2015.
Green logistics, in the context of humanitarian logistics encourages all stakeholders to consider the impact of their actions on the environment. The main objective of Green logistics is to coordinate the activities within a supply chain in such a way that beneficiary needs are met at "least cost" to the environment. It is a principle component of reverse logistics. In the past “cost” has been defined in purely monetary terms, whereas "cost" can now also be understood as the external costs of logistics associated with: climate change, air pollution, dumping waste (including packaging waste), soil degradation, noise, vibration and accidents.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

An Approach to Detecting Writing Styles Based on Clustering Techniquesambekarshweta25
An Approach to Detecting Writing Styles Based on Clustering Techniques
Authors:
-Devkinandan Jagtap
-Shweta Ambekar
-Harshit Singh
-Nakul Sharma (Assistant Professor)
Institution:
VIIT Pune, India
Abstract:
This paper proposes a system to differentiate between human-generated and AI-generated texts using stylometric analysis. The system analyzes text files and classifies writing styles by employing various clustering algorithms, such as k-means, k-means++, hierarchical, and DBSCAN. The effectiveness of these algorithms is measured using silhouette scores. The system successfully identifies distinct writing styles within documents, demonstrating its potential for plagiarism detection.
Introduction:
Stylometry, the study of linguistic and structural features in texts, is used for tasks like plagiarism detection, genre separation, and author verification. This paper leverages stylometric analysis to identify different writing styles and improve plagiarism detection methods.
Methodology:
The system includes data collection, preprocessing, feature extraction, dimensional reduction, machine learning models for clustering, and performance comparison using silhouette scores. Feature extraction focuses on lexical features, vocabulary richness, and readability scores. The study uses a small dataset of texts from various authors and employs algorithms like k-means, k-means++, hierarchical clustering, and DBSCAN for clustering.
Results:
Experiments show that the system effectively identifies writing styles, with silhouette scores indicating reasonable to strong clustering when k=2. As the number of clusters increases, the silhouette scores decrease, indicating a drop in accuracy. K-means and k-means++ perform similarly, while hierarchical clustering is less optimized.
Conclusion and Future Work:
The system works well for distinguishing writing styles with two clusters but becomes less accurate as the number of clusters increases. Future research could focus on adding more parameters and optimizing the methodology to improve accuracy with higher cluster values. This system can enhance existing plagiarism detection tools, especially in academic settings.
2. Introduction
In last few decades, depletion of natural resources and its impact on
environment have attracted significant attention of government and business
communities across the globe
Businesses are now realising that adopting green practices in different stages
of the SC not only helps to make a greener environment for future generation
Also opens multiple avenues for process innovation and improvement
Increasing regulatory norms and customers’ awareness, organizations with
greener processes would be able to maintain sustainable competitive
advantage over their competitors
3. GREEN PROCESSES IN SUPPLY CHAIN
It is inferred that research on almost every sub-field of green supply chain
(SC) has increased in last decade
The sub-field of Green SC is as follows
Green Design
Green Manufacturing
Green Logistics
Disassembly
Remanufacturing
4. Green Design
Green design or environmentally conscious design is concerned with designing
products, which are ecologically sustainable
It reduces the adverse environment impact of product by designing a product that
requires less energy and emits less emission in manufacturing process and while in
use
Adopting green design practices can help to improve the greenness of
manufacturing process
Green design is also considered as the key drivers for innovation, improved brand
positioning and improved business communication
In early days green design focus on discussing the designing of products that
generate less emission both during production phase and customers’ usage
when life cycle data became available, the green design objective in literatures
shifted from few stages of product life cycle to the complete life cycle of the
product
5. Green design – Methods and Practices
Green design objectives are incorporated in design practices in the following
ways:
referring design checklist which is developed over time by feedback from downstream
supply chain agents
referring to standard manual and guidelines such as TS 16949 and ISO 14001
consulting with environmental expert who can be part of design team or who is part
of function which approves the design for environment or who can be external to
organisation
To develop guidelines considering pressure from external agencies
Eco-QFD, which is based on the same principle of QFD (Quality Function Deployment)
used for capturing voice of customer,
adopt life cycle design approach to address the green design requirement
design decision methodology which helps the designer in designing a product using
product-hierarchy without a tradeoff on the economic issue
6. Green design – Methods and Practices
Involve users in design process so that their preferences for alternative green
product weighed against their environmental aspect can be identified which
will yield in sustainable green design
The Application of CAD (Computer-Aided Design) to help designing the product
with lower assembly and disassembly cost
Eco-opti-CAD, a method, which optimizes LCA (Life Cycle Assessment) data for
product structure design
Traditionally, green design has been limited to achieve green product and green
processes, which covers all the activity at the industry level
Extending traditional life cycle approach to cradle-to-cradle approach, an eco-
effective approach considering the impact of resource consumption
7. Green design – Methods and Practices
Apart from the scope of green design, it is also important to discuss the
environmental issues which are addressed by green design solutions
Green design solution helps to address the following issues
Reduction in energy consumption (designing product which is human powered)
Increment in material reuse ( leader-follower joint optimization to address
green design with material efficiency )
Design for reverse logistics to harvest disposable product
Reduction in emission
8. Challenges to green design
Although, green design is important for improving environmental performance of
product, its adoption in industry is full of challenges
Adoption is affected by external and internal hindrances
External hindrances directly relate to economic performance and competitive
advantage of product
Due to low economic gain achieved through eco-friendly product, top management
and middle management provide little support to green design adoption in supply-
chain processes
Those Organisations, driven towards green design, are driven by regulatory pressures
rather than proactive concerns such as economic gain
Internal hindrances relate to resource commitment and competency of organisation
Companies lacking previous experience in green design practices will face problem
in adopting green design Lack of cross functional teams (CFT) approach to solve the
problem will also affect the successful adoption of green practices
9. Challenges to green design
Companies lacking previous experience in green design practices will face
problem in adopting green design Lack of cross functional teams (CFT)
approach to solve the problem will also affect the successful adoption of
green practices
Apart from challenges to adoption of green design methods effectiveness of
green product development towards environmental performance
Green product development and stricter environmental standards might not
necessarily benefit the environment
10. Green Manufacturing
Manufacturing processes involve transformations of product from raw material
to finished product
These processes generate waste in forms of emission and product residual
Green manufacturing aims to reduce such adverse effect of manufacturing
processess
11. Green manufacturing methods
a green manufacturing metric to improve the greenness of individual process, and
developed a four-step framework which includes
evaluate the current greenness score,
prepare improvement plan,
implement the plan,
sustain the improvement
green manufacturing have focused mainly on the selection of green technology
and green material for manufacturing, and on production scheduling to achieve
green objectives
12. Challenges to green manufacturing
The key challenges in implementing green manufacturing practices are
related to financial challenges, technological challenges, and lack of
awareness and unwillingness of organisations
There is greater chances that products may meet the end of life green
objectives expected by customers even though its production processes may
not be green
Regulatory pressures are the key driver of the implementation of green
processes
Small Scale enterprises those are not registered as industrial manufacturer or
not approachable for environmental scrutiny may not deploy greener
practices in manufacturing processes
13. Green Logistics
Logistics is the management of the flow of goods from source to destination
for the purpose of satisfying the csutomer demand
Key logistics processes are material handling, packaging and unwrapping of
products, warehousing and transportation
Green logistics attempts to minimise the adverse environmental effect of
these logistics processes
Addresses the environmental problem by optimising the routes, minimising
the empty running of containers, reducing the fuel consumption and reducing
the emission due to the use of eco-friendly packaging material
14. Challenges to green logistics
Adopting green logistics is challenging in terms of the cost of investment,
technology and knowledge of practices, and customer response to the
products
Product coming out of the reverse logistics is considered inferior by customers
15. Disassembly
Disassembly reduces adverse environmental impact by means of product recovery
The objective of disassembly is to retrieve parts at the end of product life for
reuse, recycle and remanufacturing
The product is disassembled into components and subassemblies, which is further
disassembled into smaller components
These components are then segregated into categories of recyclable, reusable, re-
manufacturable and disposable
Thus, disassembly minimises the total quantity of waste to landfill
It is a critical step to improve organisational environmental performance
Disassembly has recently gained increased attention due to its wide utility in
product recovery
Although included in business processes, disassembly faces high uncertainty in
product quality and quantity, and therefore it needs further attention to improve
economics of business
16. Disassembly Methods
Uncertainty of quality and quantity of incoming product causes inefficiency in
operation of disassembly process
Inefficiencies in disassembly processes have an economic burden on industries
These inefficiencies may discourage industries to implement disassembly
operations
Earlier approach to disassembly was reverse of assembly, but this is an
inefficient process
Inefficiency in the disassembly process was addressed by planning sequence of
disassembly
The efficiency of sequence planning is further improved by including learning
over repetition of the job
disassembly process planning considers the effect of human machine learning
over the repetitive use of certain process/method of disassembly
17. Disassembly Methods
The uncertainty in incoming quality and quantity also affects the disassembly line
Initially in disassembly focused on the problems in disassembly associated with a
single product, later research considered balancing of multi product line (different
products disassembling into similar components)
Apart from optimised sequence planning and line balancing, disassembly
operational efficiency can be improved by designing products with joints which
takes less time and resources to disassemble
new joints are more efficient than traditional joints and are more sustainable
economically
Alternative joints can be reversible joint, thermal and magnetic lock joints
These joints can be more efficiently disassembled by applying heating and
magnetic field
18. Disassembly Methods
Environmental and economic performance of the product further can be
improved by designing the products that are economically preferable for
disassembly and further processing
Strategies for optimal disassembly and recovery
determining all possible processes of disassembly,
determining all possible recovery options available,
determining the optimal disassembly and recovery option
19. Challenges to disassembly
The small electronic components do not have any economic values if they are
considered for recycling or remanufacturing and, therefore, adoption of
disassembly for small components is not favorable
The economic feasibility of disassembly is not favourable unless its efficiency
improves
These economic challenges make it unfavourable to incorporate disassembly
into manufacturing practices
20. Remanufacturing
Remanufacturing is a process that utilises the used components, coming from
disassembly of end of life or used products to manufacture new products
The process of remanufacturing incorporates retrieval of end of life product,
segregation (sorting) of product, disassembly, cleaning, repairing, and reassembly
Remanufacturing is important for improving environment performance of the
industry by reducing the amount of materials for land filling
It has the capability to reduce the adverse environmental effects by reducing the
requirement of new components, production of which causes emissions and energy
consumptions
Remanufacturing is better if the market is competitive
However, the uncertainties in the end of life product’s quality and quantity bring
difficulty in managing remanufacturing for optimal economic performance
Therefore, it is important to devise methods that help remanufacturing to become
an economically attractive practice in the manufacturing industries
21. Methods of remanufacturing planning
Remanufacturing faces problem with incoming quality, schedule and quantity
of end of life or used product and economic feasibility of manufacturing
process
Once the decision related to remanufacturing of aftermarket product is
taken, problem associated with inventory management, production planning,
and product design arises
22. Challenges to remanufacturing adoption
Remanufacturing in developing countries such as India is in the infancy stage
Market such as India, lacks strategy for adaptation of remanufacturing in
formal business activity
There is also a lack of policy from government to guide the remanufacturing
implementation
They argued that there is confusion with understanding of terms such as
reuse, repair, recycle and remanufacture
The negative perception of quality of the remanufactured product also places
challenges for its adoption in the market
23. CONCLUSION
Research in green design has been focused on developing methods while little
emphasis is provided on adoption of the method
Green manufacturing processes can be improved in terms of environmental
performance
Research in areas such measuring green index of manufacturing processes
helps to track the current level of greenness and can promote the
improvement of process
Also, frameworks for selection of green technology can help organisations to
take decisions on adopting green technology
