Abstract

Purpose

The paper provides an overview of research published in the innovation and operations management (IOM) literature on 15 methods for cost management in new product development, and it provides a comparison to an earlier review of the management accounting (MA) literature (Wouters & Morales, 2014).

Methodology/approach

This structured literature search covers papers published in 23 journals in IOM in the period 1990–2014.

Findings

The search yielded a sample of 208 unique papers with 275 results (one paper could refer to multiple cost management methods). The top 3 methods are modular design, component commonality, and product platforms, with 115 results (42%) together. In the MA literature, these three methods accounted for 29%, but target costing was the most researched cost management method by far (26%). Simulation is the most frequently used research method in the IOM literature, whereas this was averagely used in the MA literature; qualitative studies were the most frequently used research method in the MA literature, whereas this was averagely used in the IOM literature. We found a lot of papers presenting practical approaches or decision models as a further development of a particular cost management method, which is a clear difference from the MA literature.

Research limitations/implications

This review focused on the same cost management methods, and future research could also consider other cost management methods which are likely to be more important in the IOM literature compared to the MA literature. Future research could also investigate innovative cost management practices in more detail through longitudinal case studies.

Originality/value

This review of research on methods for cost management published outside the MA literature provides an overview for MA researchers. It highlights key differences between both literatures in their research of the same cost management methods.

Abstract

Purpose

The capacity available to deliver outpatient surgical services is outweighed by the demand. Although additional investment is sometimes needed, better aligning resources, increasing operational efficiency and considering new processes all have a role in improving delivering these services. The purpose of this paper is to evaluate the safety of a physician associate (PA) delivered virtual outpatient department (VOPD) consultation service that was established in a General and Colorectal Surgery Department at an Irish teaching hospital.

Design/methodology/approach

A series of low-risk surgical patients were referred by senior surgeons to a PA delivered virtual clinic (VOPD). Medical records belonging to half the included patients were randomly selected for review by two doctors three months following discharge back to primary care to confirm appropriate standards of care and documentation and to audit any recorded adverse incidents or outcomes.

Findings

In total, 191 patients had been reviewed by the PA in the VOPD with 159 discharged directly back to primary care. Among the 95 medical records that were reviewed by the NCHDs, there were no recorded adverse incidents after discharge. Medical record keeping was deficient in 1 out of 95 reviewed cases.

Practical implications

Using a PA delivered VOPD consultation appears to have a role in following up patients who have undergone low-risk procedures irrespective of age or co-morbidity when selected appropriately. This may assist in reducing the demand on outpatient services by reducing unnecessary return visits, thereby increasing the capacity for new referrals.

Originality/value

While there are reported examples to date of virtual clinics, these relate to services delivered by registered medical practitioners. Here, the authors demonstrate the acceptability of this model of care in an Irish population as delivered by a PA.

Abstract

The present chapter attempts to highlight the vulnerabilities of female migrants as compared to non-migrants in the unorganized urban labor market. Informal female migrants working in construction, as domestic workers, tailors/boutiques, and garment workers in the urban unorganized sector of Uttar Pradesh’s selected urban locations, are covered in this chapter. Though the fact prevails that workers in the unorganized labor markets are confronted with various livelihood crunches, still those who are migrants and swelling the urban labor markets are more prone to different vulnerabilities. There is scanty literature on the situation and condition of migrants particularly female migrant workers in India, whereas we know more about the condition of international migrants, mainly migrant workers in the Gulf and other regions. The study is based on interviews with 174 female informal workers who have migrated and 222 non-migrants from various regions of the state to the urban locations of selected cities. Our study also attempts to do an in-depth, qualitative exploration of these vulnerable women’s lives and perceptions and tries to capture layered vulnerabilities, risks, and rewards confronted due to both migration and work in the informal sector. Specifically, the findings reflect upon the fact that how strong societal norms may actually prevent women from acknowledging or articulating the true reasons for their migrations.

Abstract

Purpose

A trade-off exists between product variety and supply chain (SC) performance. To help mitigate the impact on SC of increased product variety, the purpose of this paper is to examine how variety management activities including variety management strategy (VMS), supplier partnerships and close customer relationships affect SC flexibility and agility at different levels of customisation.

Design/methodology/approach

A survey-research methodology is employed using data from 363 manufacturing firms from the UK and South Korea. In particular, cluster analysis and structural equation modelling were used to evaluate the proposed model according to the level of customisation.

Findings

The results suggest that internal variety management strategy and external SC integration have a positive influence on SC flexibility and agility. Customer relationships and variety management strategies influence SC flexibility more than partnerships with suppliers whereas variety management strategies and partnerships with suppliers influence SC agility more than customer relationships. In fact, for external integration in particular, customer relationships influence SC flexibility (i.e. reaction capability) rather than agility (i.e. reaction time) whereas partnerships with suppliers influence SC agility rather than flexibility. In a high-customisation context, close customer relationships are the most effective way to increase SC flexibility, whereas partnerships with suppliers are the most effective way to increase SC agility. In a low-customisation context, a VMS and customer relationships are the most effective way to increase both SC flexibility and agility.

Originality/value

This paper suggests key variety management activities to aid managers to better manage product variety ambitions in SC under varying customisation profiles through internal and external approaches.

Abstract

The inhibition efficiency of N‐cetyl‐N,N,N‐trimethylammonium bromide (CTAB), a cationic surfactant, in controlling the corrosion of carbon steel in an aqueous solution containing 60ppm Cl, in the absence and presence of Zn2+ and also calcium gluconate (CG), had been evaluated by the weight‐loss method. Weight‐loss studies revealed that the behaviour of CTAB changed when its concentration is ≥ 150ppm. Organisation of assembly of CTAB molecules is expected to take place at this critical concentration. The protective film has been analysed using FTIR spectra. In the presence of CTAB, the protective film consists of Fe2+‐CTAB complex. In the presence of CTAB and Zn2+, the protective film consists of Fe2+‐CTAB complex and Zn(OH)2. In the presence of CTAB and calcium gluconate, the protective film consists of Fe2+‐CTAB complex, Fe2+‐gluconate complex and Ca(OH)2.

Abstract

Purpose

Using a phenomenon known as the bullwhip effect, the authors explore why additional uncertainty in the marketplace can create severe disruptions in global supply chains (GSCs). The purpose of this paper is to analyze related risks in regional vs GSCs during low and high levels of uncertainty. The authors propose and discuss a number of potential implications alongside some tactics that may help mitigate disruptions in some cases before they become terminal problems for the supply chain sustainability.

Design/methodology/approach

Monte Carlo simulation is used to generate the conditions of uncertainty and various scenarios that may emerge to challenge GSCs. Vensim software is utilized as a tool for simulation purposes. The authors considered scenarios applicable to manufacturing and retail sectors specifically because of storability property of goods.

Findings

Regional supply chains, as opposed to global ones, are more stable and reliable (less risk of disruption) during low and high levels of uncertainty. During uncertain times, upstream suppliers are at greater risk in GSCs. Firms must make strategic decisions that will secure its supply chain functionality and assess the likelihood of such events since many firms entered emerging markets.

Originality/value

Building on internalization theory, it shows that risk and survival are components of decision making that are further complicated by supply chains now operating globally in emerging markets. The paper demonstrates with simulation that GSCs are riskier than regional supply chains in low and high levels of uncertainty, particular as it relates to the bullwhip effect. It also provides recommendations about supply chain restructure and investments in communication improvements to reduce the bullwhip effect in the supply chain.

Abstract

Purpose

The purpose of this paper is to study the inhibition effect of Tween‐40 on the corrosion of cold rolled steel (CRS) in 1.0‐8.0 M HCl over the temperature range of 20‐50°C. It also aims to make an attempt to correlate both thermodynamic parameters and kinetic parameters with the inhibition effect.

Design/methodology/approach

The inhibition efficiencies of Tween‐40 are investigated by weight loss and potentiodynamic polarization methods.

Findings

Tween‐40 acts as a good inhibitor in 1.0 M HCl, and inhibition efficiency increases with the inhibitor concentration, while it decreases with HCl concentration and temperature. The adsorption of inhibitor on the CRS surface obeys the Langmuir adsorption isotherm equation. The inhibition effect is satisfactorily explained by both thermodynamic and kinetic parameters. Polarization curves show that Tween‐40 is a mixed‐type inhibitor in hydrochloric acid.

Originality/value

The experimental data have been treated with adsorption theory and kinetic equations successfully. Both the thermodynamic and kinetic parameters can be obtained, and used in explaining the inhibition effect satisfactorily.

Abstract

The corrosion rates of mild steel in a neutral aqueous environment containing 60 ppm C1 in the absence and presence of the sodium salt of amino (trimethylene phosphonic acid) (ATMP), polyacrylamide (PAA) and Zn2+ have been evaluated by the classical weight‐loss method. The formulation consisting of 50 ppm PAA and 50 ppm Zn2+ and also the ATMP (300 ppm) ‐ZN2+ (50 ppm) system shows synergistic effect while the formulation consisting of 300 ppm ATMP and 50 ppm PAA shows antagonistic effect. The formulation consisting of 300 ppm ATMP, 50 ppm Zn2+ and 50 ppm PAA has 98 per cent corrosion inhibition efficiency and 99.9 per cent biocidal efficiency. The mechanistic aspects of corrosion inhibition are based, in a holistic way, on the results obtained from potentiostatic polarization study, X‐ray diffraction technique, UV‐visible, FTIR and luminescence spectra. Found that the protective film consists of FE2+‐ATMP complex, Fe2+‐PAA complex and Zn(OH)2.

Abstract

Purpose

This paper aims to provide a detailed review of various cutting fluids (CFs).

Design/methodology/approach

Friction and wear are inevitable in machine parts in motion. The industrial sector uses various kinds of lubricants, which include engine oils, CFs, hydraulic fluids, greases, etc. to control friction and wear. The main purpose of using CF is to remove heat produced during machining and to reduce cutting forces, tool wear and energy associated with it. Thus, it increases the productivity and quality of the manufacturing process. But more than 80% of the CFs used in the industries now are mineral oil-based. These mineral oils and additives are highly undesirable because of their toxicity, nonbiodegradability, pollution and ecological problems. Hence, these petroleum-based oils in the lubrication system can be substituted with alternatives such as vegetable-based CF. Several studies are being conducted in the field of eco-friendly CFs. Because of the variance in fatty acid profile and availability, the selection of vegetable oils (VOs) is another problem faced nowadays. The present study is focused on bio-based oils and many eco-friendly additives. Various machining processes and comparisons relating to the same have also been made. The aim is to minimize the use of mineral oil and thereby introduce sustainability in production.

Findings

In this present study, bio-based oils, additives and various characteristic behavior of them in machining are being discussed. The VOs are found to be a potential base oil for industrial CFs.

Originality/value

This paper describes the importance of sustainable CFs.

Abstract

The formulation consisting of 300ppm 1‐hydroxyethane‐1, 1‐diphosphonic acid (HEDP), 50ppm polyacrylamide (PAA) and 50 ppm Zn2+ offered 99 per cent corrosion inhibition and 99 to 99.9 per cent biocidal inhibition to mild steel in neutral aqueous environment containing 60ppm Cl‐ , a situation commonly encountered in cooling water systems. The nature of the protective film formed on the metal surface was analysed using X‐ray diffraction, UV‐visible reflectance, FTIR and luminescence spectra. The film was found to be luminescent and to consist of Fe2+ ‐HEDP complex, Fe2+ ‐PAA complex and Zn(OH)2.
