Abstract

Purpose

The purpose of this paper is to develop a simulation-based value function (VF) that combines multiple key performance indicators (KPIs) into a unified Sigma rating (SR) for system-level performance assessment and improvement.

Design/methodology/approach

Simulation is used as a platform for assessing the multiple KPIs at the system level. A simple additive VF is formed to combine the KPIs into a unified SR using the analytical hierarchy process and the entropy method. Value mapping is utilized to resolve the conflict among KPIs and generate a unified value. These methods are integrated into the standard Six Sigma define-measure-analyze-improve-control (DMAIC) process.

Findings

Simulation results provided the Six Sigma DMAIC process with system-level performance measurement and analysis based on multiple KPIs. The developed VF successfully generated unified SRs that were used to assess various performance improvement plans.

Research limitations/implications

The accuracy and credibility of the results obtained from using the proposed VF are highly dependent on the availability of pertinent data and the accuracy of the developed simulation model.

Practical implications

The proposed approach provides Six Sigma practitioners and performance mangers with a mechanism to assess and improve the performance of production and service system based on multiple KPIs when conducting Six Sigma studies.

Originality/value

This paper contributes to the previous research by handling multiple KPIs in Six Sigma studies conducted at the system level using simulation and VF. The research also provides guidelines for using the different methods of weights assessment to form the VF within the DMAIC process.

Abstract

Purpose

Enhancing consumer engagement in e-commerce live streaming is critical for e-commerce operators to build relationships and create consumer loyalty. Using the stimulus–organism–response model and theories from relationship marketing, the authors develop and test an integrative conceptual framework that combines various relational bonds, affective commitment, and consumer engagement.

Design/methodology/approach

Using 327 valid responses from consumers of Taobao Live, the authors employed the software Mplus7.0 to evaluate the measurement model and the structural model.

Findings

The results empirically demonstrate that social and structural bonds positively affect consumer engagement directly and indirectly via affective commitment, while financial bonds have only an indirect effect via affective commitment on consumer engagement.

Practical implications

The findings provide useful insights for e-commerce operators, who should invest in establishing relational bonds and stimulating affective commitment to improve consumer engagement.

Originality/value

This study adds to e-commerce research by being one of the first empirical studies on e-commerce live streaming, extends the marketing literature by integrating different relational bonds as antecedents of consumer engagement from the relational perspective, and enriches the affective commitment literature by distinguishing commitment to the online marketplace from commitment to the broadcaster.

Abstract

The p‐median problem involves the locating of a fixed number of facilities to serve a set of customers such that the aggregate distance travelled is minimized. Considers the p‐median problem with and without distance constraints. Solves the two versions of the p‐median problems utilizing the heuristic proposed by Teitz and Bart using three different data sets. Also provides optimal solutions to these problems using the Lagrangian relaxation and subgradient methods in the branch‐and‐bound procedure. Shows that the heuristic performs quite well except for the cases where the constraints are tight (few facilities and/or small maximum distance).

Abstract

Aims to explore the role of management and control of quality in a process industry. Specifically, focuses on the current practices in the process of making cheese. Develops a survey instrument to measure managers’ perceptions regarding the extent to which various quality management procedures are implemented in the production of cheese. Reveals several interesting observations: for instance, many of the managers believed that implementing more quality control procedures positively contribute towards better quality, increased productivity, and improved exporting capabilities. Moreover, employee training was viewed as a critical factor to the success of TQM initiatives in organizations. Reports other interesting results relating to the different types of tests that are commonly employed during the production of cheese and whether every plant should have a separate quality control department.

Abstract

Purpose

Fast-growing online retail market provides convenience for customers. But it makes competition among online retailers fiercer as well. Online retailers need to improve online shoppers’ satisfaction level for the purpose of keeping their loyalty. As an important component in online retail market, logistics service affects online shoppers’ satisfaction level. By applying expectation confirmation theory, the purpose of this paper is to explore how customized logistics services (CLS) influences online shoppers’ satisfaction level and whether the relationship between them is moderated by product type.

Design/methodology/approach

Data were collected from Tmall.com, the biggest online retail market in China. Exploratory factor analysis and two-way ANOVA were conducted to analyze the data.

Findings

The results indicate that CLS positively impacts online shoppers’ satisfaction level. But product type does not have moderate effect on the relationship between CLS and online shoppers’ satisfaction level.

Practical implications

Online retail market grows fast. As the number of retailers keeps increasing, competition in this market becomes fiercer. In order to attract new shoppers and increase shoppers’ loyalty, online retailers must make shopper satisfied with their purchase. CLS positively impacts online shoppers’ satisfaction level, online retailers should offer shoppers CLS.

Originality/value

This study examines how customized logistics influences customer satisfaction, and extends literatures related to online customer satisfaction by integrating the factor CLS and opens the way for other studies related to logistics service customization. Furthermore, this study discusses how IoT will improve online retailers’ abilities in providing CLS.

Abstract

Purpose

The purpose of this paper is to investigate the influence of social media on employees’ work performance, as well as the underlying mechanism for how they create value at work.

Design/methodology/approach

Based on media synchronicity and social capital theories, the authors propose that social media can foster employees’ social capital and subsequently facilitate knowledge transfer. Both social capital and knowledge transfer help promote work performance. Specifically, the authors adopt shared vision, network ties and trust to represent, respectively, the cognitive, structural and relational dimensions of social capital. The research model is tested using data collected from 379 Chinese working professionals.

Findings

The empirical results reveal that social media can promote the formation of employees’ social capital indicated by network ties, shared vision and trust, which, in turn, can facilitate knowledge transfer. Shared vision and knowledge transfer positively influence work performance. Although network ties and trust do not have a direct impact on work performance, the influence is partially mediated by knowledge transfer.

Practical implications

For organizations that wish to build knowledge networks in the workplace, connecting experts with various social media can effectively complement other knowledge management technology. Further, managers should encourage employees to consciously exploit the byproducts created via social media, e.g., social capital, to promote knowledge exchange.

Originality/value

The integration of media synchronicity and social capital theories offers a new theoretical lens and reasonable explanations for investigating communication performance. The research offers empirical evidence regarding how the influence of social media on work performance is transmitted through social capital and knowledge transfer. The authors quantify social media’s benefits for organizations, providing managers an impetus to deploy them in the workplace with optimistic expectation.

Abstract

Purpose

The purpose of this paper is to explore the correlations among entrepreneurial environment, market-oriented strategies, and entrepreneurial performance.

Design/methodology/approach

Entrepreneurial environment is measured by institutional environment and industrial environment. A survey of 176 large Chinese automobile firms is conducted. The structural equation model is applied to perform analysis.

Findings

The uncertainty of the institutional environment is positively related with market-oriented strategies and market-oriented strategies are positively related with firms’ performance. The stronger the uncertainty of the industrial environment is, the larger impact that market-oriented strategies have on firms’ performance will be. There is no distinct positive relationship between the uncertainty of industrial environment and firms’ market-oriented strategies. The hypothesis, that the stronger the uncertainty of institutional environments is, the larger the impact that market-oriented strategies will be on firms’ performance, is not supported.

Research limitations/implications

In terms of research design, this paper does not select survey samples randomly. This paper only takes institutional and industrial environments into consideration while the environmental characteristics are omitted.

Originality/value

This paper expands entrepreneurship research by integrating previous studies. Findings in this paper are helpful for firms in emerging countries to implement “going abroad strategies,” to start up new businesses in other countries, and to achieve the goals of improving competitiveness and integrating with international firms.
