Abstract

Purpose

The choice of a sales channel for fresh vegetables is an important decision a farmer can make. Typically, the farmers rely on their personal experience in directing the produce to a sales channel. This study examines how sales forecasting of fresh vegetables along multiple channels enables marginal and small-scale farmers to maximize their revenue by proportionately allocating the produce considering their short shelf life.

Design/methodology/approach

Machine learning models, namely long short-term memory (LSTM), convolution neural network (CNN) and traditional methods such as autoregressive integrated moving average (ARIMA) and weighted moving average (WMA) are developed and tested for demand forecasting of vegetables through three different channels, namely direct (Jaivasree), regulated (World market) and cooperative (Horticorp).

Findings

The results show that machine learning methods (LSTM/CNN) provide better forecasts for regulated (World market) and cooperative (Horticorp) channels, while traditional moving average yields a better result for direct (Jaivasree) channel where the sales volume is less as compared to the remaining two channels.

Research limitations/implications

The price of vegetables is not considered as the government sets the base price for the vegetables.

Originality/value

The existing literature lacks models and approaches to predict the sales of fresh vegetables for marginal and small-scale farmers of developing economies like India. In this research, the authors forecast the sales of commonly used fresh vegetables for small-scale farmers of Kerala in India based on a set of 130 weekly time series data obtained from the Kerala Horticorp.

Abstract

Purpose

This paper aims to propose a new MLI topology with reduced number of switches for photovoltaic applications. Multilevel inverters (MLIs) have been found to be prospective for renewable energy applications like photovoltaic cell, as they produce output voltage from numerous separate DC sources or capacitor banks with reduced total harmonic distortion (THD) because of a staircase like waveform. However, they endure from serious setbacks including larger number of capacitors, isolated DC sources, associated gate drivers and increased control difficulty for higher number of voltage levels.

Design/methodology/approach

This paper proposes a new three-phase multilevel DC-link inverter topology overpowering the previously mentioned problems. The proposed topology is designed for five and seven levels in Matlab/Simulink with gating pulse using multicarrier pulse width modulation. The hardware results are shown for a five-level MLI to witness the viability of the proposed MLI for medium voltage applications.

Findings

The comparison of the proposed topology with other conventional and other topologies in terms of switch count, DC sources and power loss has been made in this paper. The reduction of switches in proposed topology results in reduced power loss. The simulation and hardware show that the output voltage yields a very close sinusoidal voltage and lesser THD.

Originality/value

The proposed topology can be extended for any level of output voltage which is helpful for sustainable source application.

Abstract

Purpose

Aluminum alloy AA5083 is applicable in ship building, military, railway and industry because of its excellent properties like resistance to chemical and sea water attack. However, its performance is affected by weak wear resistance. Hence, this should be solved to improve the performance of AA5083 alloy in the aforementioned fields. The purpose of this research is to enhance the wear properties of AA5083 alloy.

Design/methodology/approach

In this research, AA5083 alloy was reinforced with industrial wastes such as red mud and granite particles using stir casting method. Totally, four types of composites were fabricated, namely, AA5083/3 Wt.% red mud (C1), AA5083/3 Wt.% granite (C2), AA5083/1 Wt.% red mud-2Wt.% granite (C3) and AA5083/2 Wt.% red mud-1Wt.% granite (C4). Wear properties such as mass loss and coefficient of friction (COF) were analyzed for different wear parameters. Further, the mechanical properties like hardness and tensile strength were investigated.

Findings

Results showed that the inclusion of reinforcement particles improved the wear and mechanical properties of AA5083 alloy (C0). The C2 sample displayed the maximum hardness of 87 HV and tensile strength of 317 MPa owing to the inclusion of 3 Wt.% granite particles. Furthermore, the wear study results showed that the C2 sample displayed the minimum mass loss and COF. It was concluded from this research that C2 sample could be a good candidate to be applicable in marine, military, railway and industrial applications with improved performance.

Originality/value

This work is original as the industrial waste is used as reinforcements in the performance improvement of AA5083 aluminum alloy.

Abstract

Purpose

The purpose of this research is to investigate whether and how shopping well-being emerges from multichannel shopping. The multichannel shopper has more choice of where, when and how to shop, and could potentially experience greater shopping well-being than the single-channel equivalent. On the other hand, it is possible that multichannel shopping creates levels of complexity for consumers in terms of their channel decision processes, and therefore, the potential increase in shopping well-being may not actually occur.

Design/methodology/approach

An interpretive approach is adopted and narratives are used to provide a focus on the multichannel shopper’s lived experiences. Narrative generation was conducted with 12 participant shoppers from across the UK in March and April 2016.

Findings

Multichannel retailing does not deliver universally enhanced shopping well-being. Findings suggest that while well-being is enhanced by some aspects of multichannel shopping, diminished well-being is a more frequent outcome. Six themes emerged from the narratives delineating aspects of multichannel shopping which diminish well-being: finding what you want; ease and flexibility; staying in control; getting a fair deal; pleasure and fulfilment; guilt, regret and annoyance.

Originality/value

This research makes three contributions to our understanding of shopping well-being: by providing more in-depth insight than previous studies, by examining all shopping activity rather than recreational/discretionary shopping and by examining shopping well-being from a multichannel rather than single-channel perspective.

Abstract

Purpose

The aim of this research is to advance the understanding of multi-channel behaviour in terms of different generational cohorts' usage and spending patterns.

Design/methodology/approach

Building on previous studies on multi-channel behaviour, differences in shopping channel usage and purchase amounts were investigated between baby boomers, Gen X, xennials and millennials.

Findings

There were significant differences found between the generations in terms of multi-channel behaviour regarding purchasing frequency and average purchase amounts via a) mobile phone, b) tablet, c) computer, d) social media and e) brick-and-mortar. Fewer differences were found amongst the generational cohorts in terms of amount spent per channel.

Research limitations/implications

The research was successful in analysing variances in multi-channel behaviour amongst the baby boomer, Generation X, xennial and millennial cohorts, while updating the body of literature to consider generational channel usage of mobile and social media in multi-channel retailing.

Practical implications

Marketers should consider xennials’ channel behaviour and focus on converting sales through integrated programmes based on their channel usage. Retailers should also consider millennials' heavy engagement with social media in their lives but spend lower amounts via the medium, which may be an opportunity to use this medium as a viable stand-alone channel in targeting millennials' shopping dollars.

Originality/value

This study updates the body of research on multi-channel behaviour by considering generation as a factor in channel usage and spend amount.

Abstract

Purpose

Companies with global ambitions need to pay close attention to how innovation is achieved in India. In particular, corporate leaders still have much to learn about how this economic powerhouse is likely to develop in the coming decades and what strategy and innovation plays are most likely to be successful.

Design/methodology/approach

This “Masterclass” examines the lessons from three important recent books that offer valuable insights on how Indian businesses are addressing the innovation challenge: Conquering the Chaos by Ravi Venkatesan, former Chairman of Cummins India and Microsoft India, identifies the leadership blueprint for creating most value in this and similar emerging “VUCCA” markets. India Inside by Nirmalya Kumar and Phanish Puranam discovers a significant opportunity and challenge – India's rapid emergence as a global hub of innovation. Reverse Innovation by Vijay Govindarajan and Chris Trimble presents an alternative strategy to “glocalization” as a more promising way to drive global growth, using emerging markets like India as the innovation platform.

Findings

The article looks at why only 25 to 30 of the more than 1,300 major multinationals currently operating in India have made it into the “high-growth trajectory, market leadership” category within that country.

Practical implications

Every company with global ambitions would now be well advised to make to make innovation in India central to their own ambitions, so that they might become the global disruptors of the future not the victims.

Originality/value

While most of today's multinational CEOs see pursuing significant market participation in China as a “no-brainer,” rising, or failing to rise, to the challenge of India, with at least as much urgency and commitment, may turn out to be their most “defining” strategic legacy.

Abstract

Purpose

The purpose of this paper is to evaluate the influence of price and products on the promotion (through in-store temporary displays) on consumer sales in an emerging market context (i.e. Brazil) in different regions with contrasts in the market and store formats analyzed.

Design/methodology/approach

The data originate from retail market audits conducted over three years and are broken down by a region and a channel for a product category that has experienced increased competition and growth and is highly distributed throughout the analyzed regions and channel formats (i.e. the ready-to-drink juice category). This study uses a panel vector autoregression framework and an impulse-response function to determine the effects on sales over time.

Findings

The results suggest that price sensitivity and the effects of promotions on sales vary with the type of store format rather than through structural differences between regions with lower vs higher levels of economic development in an emerging market.

Practical implications

Managers should consider differences in store format more than the heterogeneity among regions when making price and promotion decisions. Additionally, this paper highlights the importance of in-store product visibility through temporary displays of promoted products, especially in smaller stores in an emerging market.

Originality/value

By considering the challenges of managing a consumer brand for which market heterogeneity is key, this paper extends the current research by contrasting consumer price and in-store promotion decisions across two heterogeneous regions and store formats within an emerging market.

Abstract

Purpose

The application of digital twins to optimise operations and supply chain management functions is a bourgeoning practice. Scholars have attempted to keep pace with this development initiating a fast-evolving research agenda. The purpose of this paper is to take stock of the emerging research stream identifying trends and capture the value potential of digital twins to the field of operations and supply chain management.

Design/methodology/approach

In this work we employ a bibliometric literature review supported by bibliographic coupling and keyword co-occurrence network analysis to examine current trends in the research field regarding the value-added potential of digital twin in operations and supply chain management.

Findings

The main findings of this work are the identification of four value clusters and one enabler cluster. Value clusters are comprised of articles that describe how the application of digital twin can enhance supply chain activities at the level of business processes as well as the level of supply chain capabilities. Value clusters of production flow management and product development operate at the business processes level and are maturing communities. The supply chain resilience and risk management value cluster operates at the capability level, it is just emerging, and is positioned at the periphery of the main network.

Originality/value

This is the first study that attempts to conceptualise digital twin as a dynamic capability and employs bibliometric and network analysis on the research stream of digital twin in operations and supply chain management to capture evolutionary trends, literature communities and value-creation dynamics in a digital-twin-enabled supply chain.

Abstract

The influence of thiophenol on the corrosion and hydrogen permeation 1M HCl and 0.SM H2SO4 has weightloss measurements, gasometric studies and other electrochemical techniques. Thiophenol inhibits the corrosion of mild steel in both the acids, but it is found to be more effective in H2SO4. It behaves predominantly as a cathodic inhibitor. It brings down the permeation current in both the acids, but is more effective in H2SO4. The adsorption of thiophenol on the mild steel surface from both the acids obeys Temkin’s adsorption isotherm.

Abstract

Purpose

The purpose of this paper is to present a quick inspection method based on the post-flight data to examine static aeroelastic behavior for transport aircraft subjected to instantaneous high g-loads.

Design/methodology/approach

In the present study, the numerical approach of static aeroelasticity and two verified cases will be presented. The non-linear unsteady aerodynamic models are established through flight data mining and the fuzzy-logic modeling of artificial intelligence techniques based on post-flight data. The first and second derivatives of flight dynamic and static aeroelastic behaviors, respectively, are then estimated by using these aerodynamic models.

Findings

The flight dynamic and static aeroelastic behaviors with instantaneous high g-load for the two transports will be analyzed and make a comparison study. The circumstance of turbulence encounter of the new twin-jet is much serious than that of four-jet transport aircraft, but the characteristic of stability and controllability for the new twin-jet is better than those of the four-jet transport aircraft; the new twin-jet transport is also shown to have very small aeroelastic effects. The static aeroelastic behaviors for the two different types can be assessed by using this method.

Practical implications

As the present study uses the flight data stored in a quick access recorder, an intrusive structural inspection of the post-flight can be avoided. A tentative conclusion is to prove that this method can be adapted to examine the static aeroelastic effects for transport aircraft of different weights, different sizes and different service years in tracking static aeroelastic behavior of existing different types of aircraft. In future research, one can consider to have more issues of other types of aircraft with high composite structure weight.

Originality/value

This method can be used to assist airlines to monitor the variations of flight dynamic and static aeroelastic behaviors as a complementary tool for management to improve aviation safety, operation and operational efficiency.
