Presents results of a quality‐management survey conducted among manufacturing companies in India, China, and Mexico. The results show that the majority of the manufacturers in the three countries are well aware of modern quality‐management concepts and philosophies. The comparisons of the survey results among the three countries show that Mexican companies generally are doing better than Indian and Chinese companies in terms of quality performance, quality improvement efforts, application of the ISO 9000 certifications, and adoption of the “quality is free” philosophy. Chinese companies show the least understanding of quality‐management principles among the three nations surveyed. In comparison to the survey results in developed countries such as Japan, the USA, Canada, and Germany, the responses from India and Mexico are comparable; the responses from China are somewhat inferior to those from the other countries.

The main objective of this research is to study the quality management practices of Indian manufacturing organizations. Presents the results of a survey conducted among the chief operating officers of medium‐and large‐size Indian manufacturing companies. Presents an analysis of the survey results. The survey investigated several quality management‐related issues including adherence to the “quality is free” philosophy, causes of poor quality, quality performance, efforts to improve quality and status of ISO 9000 certification among the Indian companies. Compares also quality practices in India with industrialized nations such as Japan, USA, Germany and Canada.

In a wireless sensor network (WSN), the sensor nodes are distributed in the network, and in general, they are linked through wireless intermediate to assemble physical data. The nodes drop their energy after a specific duration because they are battery-powered, which also reduces network lifetime. In addition, the routing process and cluster head (CH) selection process is the most significant one in WSN. Enhancing network lifetime through balancing path reliability is more challenging in WSN. This paper aims to devise a multihop routing technique with developed IIWEHO technique.

In this method, WSN nodes are simulated originally, and it is fed to the clustering process. Meanwhile, the CH is selected with low energy-based adaptive clustering model with hierarchy (LEACH) model. After CH selection, multipath routing is performed by developed improved invasive weed-based elephant herd optimization (IIWEHO) algorithm. In addition, the multipath routing is selected based on certain fitness functions like delay, energy, link quality and distance. However, the developed IIWEHO technique is the combination of IIWO method and EHO algorithm.

The performance of developed optimization method is estimated with different metrics, like distance, energy, delay and throughput and achieved improved performance for the proposed method.

This paper presents an effectual multihop routing method, named IIWEHO technique in WSN. The developed IIWEHO algorithm is newly devised by incorporating EHO and IIWO approaches. The fitness measures, which include intra- and inter-distance, delay, link quality, delay and consumption of energy, are considered in this model. The proposed model simulates the WSN nodes, and CH selection is done by the LEACH protocol. The suitable CH is chosen for transmitting data through base station from the source to destination. Here, the routing system is devised by a developed optimization technique. The selection of multipath routing is carried out using the developed IIWEHO technique. The developed optimization approach selects the multipath depending on various multi-objective functions.

COVID-19 pandemic has heavily affected worldwide. One of the major industrial sectors impacted by COVID-19 virus is the travel and hospitality, and it has resulted in extreme level of unemployment in travel and tourism industries especially hotels, restaurant chains, street food caterers and bars. Cancellations of events, conferences, conventions and sports leagues are instantaneously causing severe impact on the travel and tourism and hospitality industry. The unemployed workforce is facing numerous mental health challenges in the form of depression, anxiety, hopelessness, lack of confidence and loss of interest in life which are leading them to maladaptive coping mechanisms like suicide, alcohol and substance abuse. This chapter discusses the following topics:
