Abstract

Purpose

With the increasing competition among the industries, they remain under pressure as how to select the best set of suppliers for the competitive edge. Often, it has been challenging to develop an effective set of suppliers due to varied and asymmetric mode of criteria. The purpose of this paper is to develop a responsive chain under original equipment manufacturer (OEM).

Design/methodology/approach

This study proposes a responsive chain under a two-echelon system (TES) of OEM, which needs to collaborate with a set of suppliers at each echelon through an integrated methodology of AHP and TOPSIS. According to the OEM’s criteria, demands and suppliers’ capacity vary with time, therefore they are not static for a longer period. Hence, supplier selection (SS) problem possesses dynamicity in real practice. For this, MILP is used for finding optimal order quantities based on the optimal ranking at each echelon in the multi-period scenario. Subsequently, sensitivity analysis (SA) is conducted through Taguchi method of parameter design (TMPD) to achieve an optimal ranking in the TES.

Findings

This study suggests optimal criteria’s weight, percentage contribution, and flexibility for the suppliers and manufacturers involving through maximum demand strategy at each echelon of OEM. It also provides robust group of suppliers and manufacturers in the TES through optimal ranking and simultaneously in the order allocations. Furthermore, it restricts the number of suppliers and manufactures at each echelon through proposed methodology to obtain the solution in a very short running time.

Originality/value

To validate this model, a real data set for the case of chain conveyor company is used. This adopted methodology can suggest the organization that how the approach should be implemented.

Abstract

Purpose

Approximately, 800m tons of e-waste is generated per year in India. Reverse supply chain (RSC) is the probable strategy to cope up with the issue. Setting up a RSC process is not popular in the Indian sector. There are several factors that basically control the profitability of such kind of business. Hence, the purpose of this paper is to develop a causal model among the identified issues and sub-issues for setting up a RSC in an Indian semiconductor manufacturing industry and then evaluate the critical issues based on the causal relations.

Design/methodology/approach

Decision-making trial and evaluation laboratory (DEMATEL) method along fuzzy set theory is used to develop the causal framework among the identified strategical and tactical issues. According to the causal relations from DEMATEL, analytical network process is then used to identify the weights of the sub-issues.

Findings

The cause–effect interactions among the main issues show that legislations and regulations, market-related issues and organizational issue are the most significant strategic issues. Uncertainty in the acquisition time is the most significant tactical issue because it has a crucial impact on the quality and quantity of the used products. Based on the obtained causal relations of the main issues, it is identified that the reduction of waste, creation of new opportunity, market competition, cost reduction, change in technology and location, capacity and number of recovery facility are the major sub-issues in RSC implementation.

Practical implications

This study is conducted on the basis of the experts’ opinion from a semiconductor manufacturing industry, situated in the southern part of India. Therefore, this proves its practical implications.

Originality/value

The paper provides the detail illustration of the issues in the RSC process, and the prioritization of the issues based on the cause–effect relationships also provides some meaningful managerial insights.

Abstract

Purpose

Sustainable development comprises three bottom line concepts, i.e. protect environment, improve economic performance, and social performance. Business organization with only profitability as the primary objective may lead to a highly competitive market which mainly focuses on financial performance and pay less attention to environmental and social performance. Companies that adopt the product recovery activities also select economic performance as the prime priority of their business objectives. The purpose of this paper is to give a brief idea about a different kind of business model other than conventional business models. Here, the authors aim to represent collaboration among firms, companies, and players within a closed-loop supply chain (CLSC) to build a leading business model that establishes three basic concepts of sustainability.

Design/methodology/approach

From literature the authors identified that the primary objective of establishing a sustainable business model is environmental issues but achieving economic performance and gaining market share increase competition among companies. The authors also identified that increasing financial performance results in the development of a competitive business model. This literature review helps to represent the concept of collaborative business model, its benefit, and its mechanism and also helps to compare it with competitive business model in terms of sustainability.

Findings

In case of the collaborative business model, the authors found that collaboration is better than competition to sustain in the market. The authors described the collaborative business model and mechanism of both competitive and collaborative business strategies in a CLSC. The authors gave an idea to adopt some well-known business model and pricing policies for the collaborating firms. The authors presented a comparison between the collaborative and competitive business model and also identified different types of collaborative and completive relationship among the players within a CLSC.

Originality/value

Government legislations, e-waste rules, and environmental rules involve original equipment manufacturer (OEM) for taking back its end-of-life (EOL)/end-of-use products. A collaborative business model helps OEM to manage those huge amounts of used products by involving third parties within the supply chain. Here, in this paper the authors represent different collaborative parties and their purpose for collaboration, and also represent a strong belief that collaborative business model is the recent trend for establishing sustainability than competitive business model.

Abstract

Purpose

This paper aims to address the supplier selection (SS) problem under dynamic business environments to optimize the procurement cost of spare-parts in the context of a mining equipment company (MEC). Practically, involved parameters’ value does not remain constant as planning periods due to fluctuation in the demand and their market dynamics. Therefore, dynamicity in the parameter is considered as an important factor when a company forms a responsive chain through most eligible suppliers with respect to planning periods. This area of study may be considered for their complexities to the approaches toward order-allocations with bi-products of unused and repair spare-parts.

Design/methodology/approach

An integrated methodology of analytic hierarchy process (AHP) and mixed-integer non-linear programming (MILP) is implemented in the two stages during each planning periods. In the first stage, AHP is used to obtain the relative weights with respect to each spare-parts of each criterion and based on that, the ranking is evaluated in accordance with case considered. And in the second stage, MILP is formulated to find the allocations of each spare-part with two distinct approaches through Model-1 and Model-2 separately. Moreover, Model-1 and Model-2 are outlined based on the ranking and efficient parameters-value under cost, limited capacities, quality level and delay lead time respectively.

Findings

The ranking and their optimal order-allocation of potential suppliers are obtained during consecutive planning periods for both unused and repair spare-parts. Subsequently, sensitivity analysis is conducted to deduce the key nuggets with the comparison of Model-1 and Model-2 in the changing of capacity, demand and cost per spare-parts. From this analysis, it is found that suppliers who have optimal parameter settings would be better for order-allocations than ranking during the changing planning period.

Practical implications

This paper points out the situation-specific approach for SS problem for a mining industry which often faces disruptive supplying environments. The managerial implication between ranking and parameters are highlighted through Model-1 and Model-2 by sensitivity analysis.

Originality/value

It provides useful directions for managers who are involved in the procurement of spare-parts in the mining environment. For this, suppliers are selected for order-allocation by using Model-1 and Model-2 in the dynamic business environment. The solvability of the model is presented using LINGO 17. Furthermore, the case company selected in this study can be extended to other sectors.

Abstract

Purpose

There exists insufficient literature on classification and taxonomy of tea leaves supply chain (TLSC), so the purpose of this paper is to study the existing TLSCs and classify them accordingly. Apart from this, the paper also focuses on identification of key decisions issues in the supply chains (SC) and developing a TLSC decision framework for the state of Assam in India.

Design/methodology/approach

The paper is based on a two-year detailed study on TLSC in Assam which encompasses 22 Tea Estates, 41 Small Tea Gardens (STGs) and a Research Institute (Tocklai Tea Research Institute). Secondary data were collected from relevant websites of various government organizations of India, company’s websites, annual reports, official statements from the companies, tea market reports, annual reports of the Indian Tea Association, the Tea Board of India, Tea Research Institute and published reports, etc.

Findings

The “point of origin” of TLSC is a tea garden, “point of consumption” is considered as a tea factory and green tea leaves (GTLs) forms the basic raw material. This SC includes mainly three players: Tea leaves growers, manufacturers of made tea and tea leaves agents. This study identifies the three types of TLSCs existing in Assam: TLSC1, TLSC2 and TLSC3. Among them, only TLSC1 is both responsive as well as an efficient chain, while the rest are only responsive chains. Later two SCs can be made efficient with the proposed TLSC4.

Research limitations/implications

There is an insufficient literature on classification and taxonomy of TLSC, therefore the study (considerably the classification and taxonomy of TLSC) was developed from the primary data which were collected from the 22 Tea Estates and 41 STGs of four districts of Assam, because of limited time (two years). The study should have involved more tea estates and small tea gardens for better classification and taxonomy.

Practical implications

The proposed model suggests that small tea growers may create a co-operative whereby smaller tea gardens (STGs) (members of the co-operative) unite to act as a single large garden, set up their own co-operative factory and recruit permanent tea plucking laborers. This up-gradation of TLSC2 and TLSC3 to TLSC4 may enable a group of STGs to work in a manner similar to a Tea Estate.

Originality/value

To the best of authors’ knowledge this is one of the first studies to classify the TLSC in Assam.

Design/methodology/approach

The paper identified and categorized multiple challenges impacting machine efficiency in MC through a literature review spanning over three decades, and also ranked the identified issue-based parameters. Top issues were found varying across different types of industries identified through the review. Metrics pertaining to efficiency and degree of MC are reviewed in the paper. A chronological review of issues is presented, and a chain diagram is built in the paper. Toolkit of best practices created with solution strategies and tools are summarized through the review.

Findings

The paper found that MC reasonably impacts machine efficiency which needs to be addressed. Major issues through literature review-based ranking are uncovered, and worldwide research trend and comparison are presented. Active research in this area is observed to be at its peak since 2010. The extensive use of strategies and benchmark toolkit for improving efficiency are summarized.

Research limitations/implications

Ranking of issues has been done through a literature review; hence, there can be skewness depending on the frequency of issues researched by various authors in various areas of industries.

Practical implications

This paper is useful for manufacturing managers and companies willing to increase the size of their product portfolio and choices within their available resources without compromising machine efficiencies and, thereby, the cost. The identified issues help in providing a comprehensive issue list to the academia.

Originality/value

This paper describes what is believed to be the first study that explicitly examines the issues faced in achieving machine efficiency while manufacturing in an MC environment.

Abstract

Purpose

This paper aims to investigate entropy generation in an incompressible magneto-micropolar nanofluid flow over a nonlinear stretching sheet. The flow is subjected to thermal radiation and viscous dissipation. The energy equation is extended by considering the impact of the Joule heating term because of an imposed magnetic field.

Design/methodology/approach

The flow, heat and mass transfer model are solved numerically using the spectral quasilinearization method. An analysis of the performance of this method is given.

Findings

It is found that the method is robust, converges fast and gives good accuracy. In terms of the physically significant results, the authors show that the irreversibility caused by the thermal diffusion the dominants other sources of entropy generation and the surface contributes significantly to the total irreversibility.

Originality/value

The flow is subjected to a combination of a buoyancy force, viscous dissipation, Joule heating and thermal radiation. The flow equations are solved numerically using the spectral quasiliearization method. The impact of a range of physical and chemical parameters on entropy generation, velocity, angular velocity, temperature and concentration profiles are determined. The current results may help in industrial applicants. The present problem has not been considered elsewhere.

Abstract

Purpose

The purpose of this paper is to report the impact of thermophoresis and Brownian moment on MHD two-dimensional forced convection flow of nanofluid past a permeable stretching sheet in the presence of thermal diffusion.

Design/methodology/approach

The flow governing PDEs are reduced to ODEs by utilizing pertinent transmutations and then resolved by employing a fourth-order Runge-Kutta-based shooting technique. The energy and diffusion equations are incorporated with Brownian motion, thermophoresis and Soret parameters. The velocity, thermal and concentration attributes along with skin friction factor, local Nusselt and Sherwood number are discussed under the influence of sundry pertinent parameters and presented with the assistance of graphical and tabular values.

Findings

The results infer that Sherwood number is accelerated by Soret parameter but it controls the thermal transport rate. And also, Brownian and thermophoresis play a vital role in enhancing heat conduction process.

Originality/value

Considering the industrial applications of flow of magnetic nanofluid over a stretching surface, this paper presents the solution of the flow problem considering thermophoresis, Brownian motion, magnetic field and thermal diffusion effects. In addition, the aim and objectives of this paper fills a gap in the industry.
