A SSS problem fundamentally is a multi-criteria practice. It is a judgment of tactical significance to enterprises. The nature of this decision usually is difficult and unstructured. Optimization practices might be useful tools for these types of decision-making difficulties. During last few years, Differential Evolution has arisen as a dominating tool used for solving a variety of problems arising in numerous fields. In the current study, we present an approach to find a solution to the SSS problem using Differential Evolution in pulp and paper industry. Hence this paper presents a novel approach is to practice Differential Evolution to select the efficient sustainable suppliers providing the maximum fulfillment for the sustainable criteria determined. Finally, an illustrative example on pulp and paper industry validates the application of the present approach .

The significance of sustainable supply chain management (SSCM) is a critical corporate matter in the automobile industries that offers incredible potential for achieving better environmental performance , consumer fulfillment, pull down operating expenditures, reducing inventory investments in addition to achieving better fixed asset usage. The environment concerns, climatic changes, and additional ecological concerns in automobile industries are not only articulated by campaigners or researchers, but also by the common man as well, which has motivated the industries to focus on sustainability. The present research focuses on a DEA-based mathematical model and employs differential evolution to select the competent suppliers providing the utmost fulfillment for the sustainable criteria determined. This study aims to examine the sustainable supplier evaluation and selection practices likely to be adopted by the Indian automobile industry for their products.

Changing climatic conditions and environmental deterioration has multi dimensional impact on every sphere of life forms and life form driving processes. Public hold on corporations responsible for ecological misconduct in their supply chains getting more firm with time. To counter the threat it's a high time industries started taking initiatives for sustainability in their supply chains. In spite of that, suppliers often are unsuccessful to appropriately contribute in these initiatives. Hence, present paper justifies the supplier involvement in sustainable initiatives in supply chain management (SCM) with using differential evolution (DE) to select the efficient sustainable suppliers providing the maximum fulfillment for the sustainable criteria determined. Finally, two illustrative cases on automotive industry validate the application of the present approach.

This can be accomplished through the better quality control system, yet many organizations never invest their time to understand how their management system really works. To stay in today's globalize competitive market the implementation of quality circle concepts is very much useful. Quality circle is a philosophy, which deals with the real problems in the company by the contribution of a group of people. Quality circle is the group of people from any department, to solve the problem of any kind to improve the quality of something. In the quality circle the members meet at a decided interval to discuss the solutions of the problem. This paper addresses the application of quality circle concepts to implement the new attachment in the webalinzer machine to print on fabric while rolling it. By this paper we can see that how we can implement quality circle concept for solving the problem of any type with the best suitable option. With the use of their own resources and by the discussion, how the problem can be solved. In short, if we work together and we are open for the ideas then any problem can be solved by the coordination .

The deceleration was expected and in line with a soft patch in global growth and trade, which reflected the withdrawal of stimulus measures and the fading of positive impulses from the inventory cycle. Within an uncertain and risky business environment and global competition, firms have to manage not only their internal operations but also all the processes and relationships within their value chains. The purpose of this study is to provide insights for the Eurozone crises, particularly the Europe and emergingmarket economies.

The present article provides an extensive literature review of the application of GA on supply chain management (SCM). SCM consists of several intricate processes and each process is equally important for maintaining a successful supply chain. In this paper, eight processes (where each process has a set of sub-processes) as given by Council of SCM Professionals (CSCMF) are considered. The idea is to review the application of GA on these aspects and to provide the readers a detailed study in this area. The authors have considered more than 220 papers covering a span of nearly two decades for this study. The analysis is shown in detail with the help of graphs and tables. It is expected that such an extensive study will encourage and motivate the fellow researchers working in related area; to identify the gaps and to come up with innovative ideas.

By combining Lean and Six Sigma it is possible to achieve highly effective improvements in a company's operations. Six Sigma doesn't focus on speed. And, Lean cannot bring a process under statistical control. Lean Six Sigma efforts tend to be aligned by organizational functions rather than supply chains. This can result in departmental improvements, but fall short in achieving end to end supply chain improvements. Supply chain management (SCM) is a major issue in many industries as organizations begin to appreciate the criticality of creating an integrated relationship with their suppliers and customers, as well as all other stakeholders. It is concerned with smoothness, economically driven operations and maximizing value for the end customer through quality delivery. Hence, research is undertaken to integrate lean Six Sigma and SCM that will focus on how their integration drives rapid focused product and process improvements which result in controlled, sustainable, and validated improvements to the bottom line.

A case study of Inlet manifold of engine and Rotor of disk break is taken here to demonstrate the method. While working on this objective the aim will be to reduce the lead time required for tooling required for the conventional block-type investment casting process. There are strong incentives to reduce costs while increasing speed and accuracy in the current market. RP is an ideal method when the components are complex in shape because it substantially compresses the time for developing prototypes, patterns and tooling. This method is even more promising on cost and time front. The capabilities to fabricate freeform surfaces, inbuilt cores, projections and supports are the unbeatable strengths of RP processes. The use of benefits in terms costs have proved that the adoption of RP technology is techno-economically justifiable for the Indian manufacturing industries. Rapid Prototyping have proved to be a cost-effective and time efficient approach for development of pattern making, thereby ensuring possibility for technology transfer in Indian manufacturing industries.

Competition, in other words, determines in what direction one must go, in setting the value content in order for a product or a service to be competitive. This best value is determined by two considerations: performance and cost. Value analysis helps in identifying unnecessary costs of any product by focusing on the product function. Using creative ideas invariably minimizes unnecessary costs even if it does not eliminate them totally. This paper addresses the application of value analysis concepts for cost reduction in the galvanization process. By this paper we can see that how we can use value analysis concept for solving the problem of any type with the best suitable option of reducing the cost of galvanization to the best possible extent. In short, Value analysis is versatile and a systematic way solve to many problems related to any aspect of manufacture, such as quality, production, maintenance, parts availability and many others. It directly contributes to improvement of operating performance and reduced costs.

It is also well recognized that overall supply chain focus should be given an overriding priority over the individual goals of the players, if one were to improve overall supply chain surplus. Therefore, supply chain performance has attracted researcher’s attention. A variety of soft computing techniques have been employed to improve effectiveness and efficiency in various aspects of supply chain management. The aim of this paper is to summarize the findings of existing research concerning the application of soft computing techniques to supply chain management.
