In recent years, growing market competition has made companies increasingly dependent on their suppliers, which requires effective management of their supply chains. To establish and maintain relationships with the best suppliers, companies apply strategic supplier selection, evaluation, and development criteria. The literature review showed the importance of supply chains and the use of strategic criteria in managing relationships with suppliers. Based on the model proposed by Oflac, the authors studied a local subsidiary of a global company of components for the automotive industry. Through this case study, it was possible to understand how a firm establishes strategies and performs in the practice its supply relationship management activities. Results suggest that the existence of strong and continuous relationships creates advantages for companies, allowing them to remain competitive in the markets. The strategies of selection, evaluation, and development of suppliers enable companies to filter the best partners and develop their capabilities to achieve greater profits.

A global supply chain is a core element for an organization's competitiveness. Its success relies on the synchronization of relations, activities, and agreements in order to be flexible, agile, high quality, and cost effective for customers. Strategic sourcing emerges as an important factor to support and integrate the suppliers into the supply chain intelligently. This chapter aims to provide the understanding of how strategic sourcing can contribute to improving a firm's global supply chain competitiveness. In order to do so, it explores the elements to be considered while developing the strategic sourcing: the sourcing process cycle, internal and external relations, sourcing risks, global sourcing application, and supplier development.

Research on sustainable supply chain management (SSCM) has been garnering interest because of its multi-approach in nature. SSCM has emerged as an essential method for organizations to develop and to enhance their competitive strategy through innovative ways in order to satisfy customer basic needs. It facilitates competitive advantage, faster flow of information, material, less response time, speeding up delivery action, better relation and coordination among partners, easy way of information sharing, and increasing order fulfilment rate. Implementing SSCM in organizations like thermal power plants has other benefits such as increasing attention about environmental performance intending the integration of social as well as economic performance. In this chapter, the artificial neural network (ANN) method is used to measure the customer satisfaction after implementing SSCM by thermal power industries.

Businesses around the world experience many challenges to acquire raw materials, parts, subassemblies, and the other necessary inputs to their production systems. As businesses are all moving into the e-commerce platform to gain market share, they realize that electronic supply chain management (e-SCM) powered by enterprise resource planning systems (ERPs) are the new norms and no business organization can operate without both in the new world of e-commerce. Little attention has been devoted to e-SCM dynamic with ERP and the challenges they pose to organizations. In the e-commerce environment, e-SCM is among the most important factors to organizational success. Effective e-SCM can enhance competitiveness and increase market share leading a higher profitability. Nevertheless, the new e-SCM professionals and other actors must understand the factors that undergird e-SCM performance, their drivers, and the necessity of fully functional ERPs for an effective e-SCM.

Within the agricultural sector, it becomes essential worldwide to analyze the magnitude of OHS problems. However, there is a lack of study in Odisha (India) to assess the prevailing situations. Hence, an attempt was made in this study to explore the issues related to OHS among the farmers of Odisha in India. There is a dual main contribution in this study. At first the occupational health and safety issues of farmers of Odisha in India were analyzed based on the literature review and the data collected by personal interaction and questionnaires. In the second part, the step-wise weight assessment ratio analysis (SWARA) method was used to rank the different farming processes, as well as different risks involved in various farming activities.

During the early 2000s, the advent of internet and e-communication enabled organizations to be more responsive and cater to their customers' needs in a better way. Over the last few years, integrated technologies and ERP systems has allowed organizations to gain market share and establish themselves as e-commerce players. This has been achieved through better synchronization, business realignment, and operational flexibility. The rapid development in fields of information technology has transformed old partnerships between suppliers, buyers, and service providers into a more collaborative business process where information and knowledge sharing is a key success parameter. Through enhanced IT capabilities, SMEs can cooperate to form a network and promote their joint capacities to acquire a complex project and integrate resources for a better planning and execution. In this chapter, the author seeks to highlight the importance for e-SCM to be implemented and adopted, current status of adoption through case studies, benefits of e-SCM as strategy and challenges plaguing adoption of e-SCM.

All companies are dependent on their raw material providers. The same applies in the case of thermal power plants. The major raw material for a thermal power plant is the coal. There are a lot of companies which in turn provide this coal to the thermal power plant. Some of these companies are international; some are local, whereas the others are localized. The thermal power plants look into all the aspects of the coal providing company, before settling down for a deal. Some people are specifically assigned to the task of managing the supply chain. The main motive is to optimize the whole process and achieve higher efficiency. There are a lot of things which a thermal power plant looks into before finalizing a deal, such as the price, quality of goods, etc. Thus, it is very important for the raw material providers to understand each and every aspect of the demands of the thermal power plant. A combination of three methods—Delphi, SWARA, and modified SWARA—has been applied to a list of factors, which has later been ranked according to the weight and other relevant calculations.

As the supply chains become more global, the operations (such as procurement, production, warehousing, sales, and forecasting) must be managed with consideration of the global factors. International trade is one of these factors affecting the global supply chain operations. Estimating the future trade volumes of certain products for specific markets can help companies to adjust their own global supply chain operations and strategies. However, in today's competitive and complex global supply chain environments, making accurate forecasts has become significantly difficult. In this chapter, the authors present a novel big data analytics methodology to accurately forecast international trade volumes between countries for specific products. The methodology uses various open data sources and employs random forest and artificial neural networks. To demonstrate the effectiveness of their proposed methodology, the authors present a case study of forecasting the export volume of refrigerators and freezers from Turkey to United Kingdom. The results showed that the proposed methodology provides effective forecasts.

Job shop manufacturing processes have been reluctant to adopt enterprise resource planning systems (ERPs) for enhancing logistics performance. The cost of adopting and deploying ERPs is a high-entry barrier. Prior research has claimed that performance can be enhanced by improving logistics planning using technology such as ERPs. Most past research has examined the effect of ERPs on logistics performance in production processes other than job shops, which seems to suggest that in small-scale production processes the cost of ERPs makes it irrelevant. Are manufacturing job shop production processes the exception that proves the rule? Using both a t-test two sample for means and a Kolmogorov-Simonov (KS) test, this study tested whether or not ERPs can improve supply chain logistics performance in job shop manufacturing processes. The results might lead to a positive social change in the adoption or non-adoption of ERPs in job shop manufacturing.
