The MEWMA chart is one of the traditional multivariate charts which are widely employed in inspecting the quality of manufacturing and services. This chart is created through monitoring the small shifts of mean vectors of variable quality characteristics. Often in practice, the measurement of a quality characteristic produces uncertain, incomplete values, so that ambiguous numbers are obtained. In this condition, a neutrosophic-based control chart can overcome the problem resulting from the ambiguous data. The paper’s objective is to construct a new multivariate monitoring scheme based on a neutrosophic chart, namely the neutrosophic Multivariate EWMA (NMEWMA). Furthermore, the performance of the new multivariate monitoring scheme is evaluated in detecting process shifts employing the Average Run Length (ARL) and Standard Deviation Run Length (SDRL). This control chart is an innovation in the quality monitoring of uncertain data. The research result obtained indicates that the NMEWMA chart performs better than the MEWMA in finding the small mean shifts as well as in the real case application.

Based on a non- probability sample of 200 respondents from logistics and maritime transport service companies. The relationship between variables was analyzed using structural calculation modeling. The results showed that five out of the nine hypotheses were all positively and significantly supported (supply to services quality, transportation to cost, transportation to services quality, transportation to time and warehousing to cost). While the relationship between (supply to cost, supply to time, warehousing to service quality, warehousing to time) were not supported. The study focuses on the one maritime service provider in Oman, thus precluding the generalizability of findings to other logistics service or logistics areas.

In Indonesia, the success of coal extraction largely depends on the role of mining contractors. One of these successes is determined by proper asset management amidst uncertainty in the coal business, such as sustainability and digitalization issues. However, research that identifies the role of asset management in improving the performance of mining projects is still rare. Therefore, this research investigates the impact of Information technology capability, sustainability practices, and asset management on improving the performance of coal mining contractor projects in Indonesia. This research uses quantitative methods, with questionnaire data filled in by 128 project managers of mining contractor projects spread across Indonesia and analyzed by applying structural equation modeling (SEM). The findings indicate that Information technology capability and sustainability practices have a substantial and beneficial effect on improving asset management, which then enhances the performance of mining contractors. Interestingly, there is no direct impact of Information technology capability and sustainability practices on the operational performance of mining projects, so asset management is highly needed. The originality of this study is in the recognition of asset management as a valuable asset for firms that have integrated Information technologies & sustainability practices, as it promotes improved operational performance of projects, and there is still rarely any previous research that examines sustainability practices and asset management, especially mining projects. This research contributes to developing the resource-based view (RBV) theory and also contributes managerially to the practices that mining contractors must carry out when dealing with uncertain business situations.

This study aims to examine the mediating role of social media marketing effectiveness in the relationship between customer engagement dimensions (cognitive, emotional, behavioral, transactional, and social) and brand loyalty in the context of Amazon as a retail brand store. A quantitative approach was adopted, employing a survey-based method to collect data from 320 consumers who engage with Amazon as a retail brand store on social media platforms. Findings reveal positive effects of cognitive, emotional, transactional, and social engagement on brand loyalty and social media marketing effectiveness. However, behavioral engagement exhibited a negative impact. Social media marketing effectiveness positively influenced brand loyalty and mediated the relationships between customer engagement dimensions and brand loyalty. This study contributes to literature by challenging assumptions and providing insights into the interplay among customer engagement dimensions, social media marketing effectiveness, and brand loyalty. This offers brands the opportunity to promote and increase their awareness with the use of social media to interact with existing customer base that will boost loyalty in the long run. Only a few studies have examined social media marketing effectiveness as a mediator between customer engagement dimensions and brand loyalty. Therefore, this work endeavors to fill this gap by investigating consumer engagement, social media marketing and brand loyalty in an age when the internet plays an important role.

Moreover, there are several lessons from this research for businesses operating under stiff competition but with the increasing needs of modern-day consumers.

Coal mining is a very important sector in Indonesia, but there has been a decline in the realization of coal production in recent years, so this can reduce state revenues. One of the big challenges in the mining sector is the uncertainty of the mining business, such as information technology and sustainability concerns, that affect the mining industry's supply chain procedure. The purpose of this examination is to identify and determine the performance of supply chain resilience in the face of business uncertainty by determining the function of IT capabilities and sustainability practices in coal mining contractors. This research was conducted using a quantitative research method approach that was carried out using a structured survey instrument. The methodology employed in this study is built on purposive sampling, which is a non-probability selection method. The researchers used the Structural Equation Model (SEM) to examine data that were gathered from a sample of 128 project managers of coal mining contractors in Indonesia. The findings of this study demonstrated that project operational performance was significantly and favorably impacted by supply chain resilience. Additionally, a major and advantageous mediating IT skill in the operational execution of projects is supply chain resilience. Furthermore, it was shown that the use of IT capacity and the implementation of sustainability practices had a noteworthy and favorable influence on enhancing the performance of mining contractor projects. This research also provides information that environmental dynamism does not significantly moderate supply chain resilience on mining project performance. The novelty of this research is the contribution of supply chain resilience as an important resource for organizations that are integrated with IT capabilities to encourage increased project operational performance, especially for coal mining contractors. Additionally, research is still rarely carried out in between sustainability practices and supply chain resilience in the mining sector. It is concluded that coal mining contractor projects need to build supply chain resilience at the site amidst the uncertainty of the coal mining business.
