Abstract

Purpose

The business environment is changing and so are the rules of doing business. Constant innovation is the key to win in this dynamic marketplace, so that the new ideas get converted into new marketable products quickly with the least possible mistake. One way to inculcate innovation is by the participation of customers in the new product development (NPD) process. Platforms like social media has provided an opportunity for firms to communicate, co-create and collaborate with customers. The present study aims to understand the customers' participation in three phases, namely idea generation, development and commercialization of the NPD process for its effectiveness.

Design/methodology/approach

With the help of review of existing literature, a theoretical model is proposed. This model is then empirically evaluated with data of 213 respondents using structural equation modelling (SEM). The respondents are majorly young social media users in India.

Findings

The results highlight that customer involvement is important in idea generation and commercialization phase of NPD process for its effectiveness. Also, the effectiveness of NPD process affects the financial performance of the firm. The use of social media is considered for its mediating role in NPD process effectiveness during the three phases. The results show that it has an effective role to play during the idea generation phase.

Originality/value

Consumers’ perspective concerning usage of social media for their participation in NPD is an unexplored area in general and in the Indian context in particular. To fill this research gap the present study is carried out.

Abstract

Purpose

This paper aims to develop a capacitor position in radial distribution networks with a specific end goal to enhance the voltage profile, diminish the genuine power misfortune and accomplish temperate sparing. The issue of the capacitor situation in electric appropriation systems incorporates augmenting vitality and peak power loss by technique for capacitor establishments.

Design/methodology/approach

This paper proposes a novel strategy using rough thinking to pick reasonable applicant hubs in a dissemination structure for capacitor situation. Voltages and power loss reduction indices of distribution networks hubs are shown by fuzzy enrollment capacities.

Findings

A fuzzy expert system containing a course of action of heuristic rules is then used to ascertain the capacitor position appropriateness of each hub in the circulation structure. The sizing of capacitor is solved by using hybrid artificial bee colony–cuckoo search optimization.

Practical implications

Finally, a short-term load forecasting based on artificial neural network is evaluated for predicting the size of the capacitor for future loads. The proposed capacitor allocation is implemented on 69-node radial distribution network as well as 34-node radial distribution network and the results are evaluated.

Originality/value

Simulation results show that the proposed method has reduced the overall losses of the system compared with existing approaches.

Abstract

The ever increasing challenges of business environment in the recent past has taught the practitioners of data mining and customer relationship management (CRM) much about delivering high‐return and efficient results. Many service sector organizations including banks are now using data mining techniques to analyze the performance of service/customer relationships. The scope of data mining in business is enormous and thus the organizations including banks are applying data mining techniques to gain competitive advantages in their business. They are maintaining customer data in data warehouses and apply data mining software to uncover trends in the customer behaviour and understand their true business value. The organizations need an evaluation model to select the right data mining tools so as to avoid wrong decision. However, from the survey of literature, it is found that there is a gap in research in the design of an evaluation model for data mining software. In view of the importance of the subject and the existing gaps in reseach, this paper proposes a model for evaluating the data mining software with special reference to one of the leading banks in India, which have successfully implemented the data mining for CRM systems. The thus proposed model would provide a framework to evluate and to select the right data mining software which can be used by the service industry in general and the banking industry in particular.

Abstract

Purpose

Most of the studies in the field of homesickness are confined to students; this study aims to explore the feeling of homesickness among working professionals. Also, it tends to examine individual differences in the experience of homesickness across employees of different gender, ages, experience, family type, etc. The study also aspires to compare homesickness among military and civil employees.

Design/methodology/approach

The study explores five dimensions of homesickness, namely, missing family, missing friend, rumination about home, feeling lonely and adjustment problems. The collected data is subjected to reliability, validity and confirmatory factor analysis. Further, t-test and analysis of variance are used to explore homesickness differences across soldiers and corporate employees.

Findings

The study reveals that homesickness is significantly higher for employees in the male, unmarried, nuclear family, above the age of 45 years, and below the graduation category. Also, defense people experience more homesickness than civilian employees.

Originality/value

This study is one of the pioneer studies that compare homesickness among defense and civilian employees. Also, variables such as type of family, the experience of employees and marital status have hardly been explored in the literature of homesickness.

Abstract

Purpose

The purpose of this paper is to deal the adaptation of a direct torque control (DTC) strategy, originally dedicated to three level three leg inverter fed induction motor (IM) drives, following a leg failure that required the reconfiguration of the inverter from three to two legs.

Design/methodology/approach

In case of troubles with one leg of a three level inverter, it is interesting in some applications to keep operating using the two remaining legs. So, after the detection and isolation of the faulty leg, the drive connection should be rearranged with the connection of the motor phase, previously linked to the faulty leg, to the mid point of the DC-bus voltage, leading to a three level two leg inverter topology (also called bridge B8-inverter).

Findings

It has been found that the IM drive exhibits better performances under the proposed DTC strategy dedicated to the reconfigured inverter than those yielded by the DTC of the IM drive under healthy operation of the inverter. It has been noticed that the only drawback affecting the reconfigured inverter fed IM drive is the speed range limitation.

Research limitations/implications

This work should be extended by an experimental validation of the proposed DTC strategies.

Originality/value

The power factor of the reconfigured three level inverter fed IM drive is higher than the one yielded by the three level three leg inverter fed one. This represents a crucial cost benefit.
