The proposed supply management model is based, firstly, on realizing a Kraljic matrix to obtain a purchasing strategy, and then followed by the homologation of suppliers who are mainly willing to work with an inventory managed by suppliers (VMI) system. The process aims to reduce the delay time in the acquisition of R1600 loader parts so as to meet the customer in 52 days, the frame established by the company under study in reference to the average of 45 days as the sector standard for the same item.

Rolling element bearing is one of the most critical components of rotating machinery. Its failure can be catastrophic and often results in both human and material losses. This paper presents a machine learning model to predict the wear process phenomena and remaining useful life of a bearing element using classification and regression techniques respectively. An algorithm is developed to recognize the underlying mapping function directly from the data using machine learning principles. Pearson correlation methodology is used to track the important features associated with the evolution of wear and understand its progression. Further, backward elimination technique with ordinary least squares regression results was used to track features for predicting the remaining useful life. The proposed approach is illustrated on a bearing failure data set from the national aeronautics and space agency. This study will be useful in forecasting the fault status of the bearing before it causes any major loss.

Specialised laboratories and learning factories can play a significant role in developing and advancing the Industry 4 concept and production systems. However, there are many challenges that need to be addressed before creating qualified laboratories that have true Industry 4 characteristics. Some of those challenges originate from the varied definitions of Industry 4, from what different institutions and research groups consider critical/trivial to implement in a laboratory, from Universities' policies and regulations, and even taxation rules. Many challenges derive from the complexity of the Industry 4 eco-system and its continuous evolution. The objective of this paper is to provide a systematic analysis of the challenges in implementing viable Industry 4 laboratories in academia. These challenges need to be defined explicitly before they can be addressed, and relevant laboratories developed to maximise the success of what can be significant investment.

Realization of project benefits is considered to be a reflection of project success and is therefore directly linked to organisational performance. However, the failure of projects to achieve their expected outcomes continues to remain a concern, particularly for publicly funded projects. An emerging body of literature suggests that the assessment of a project's capacity to deliver organizational outcomes should be considered within the broader context of ‘project benefit realisation’ or ‘project benefit management’. This paper first develops a conceptual framework capturing the various elements and perspectives of project benefits management applicable to infrastructure projects, and then validates it using empirical data drawn from multiple sources within public sector infrastructure organisations. The findings indicate that pursuance of the proposed framework could support the delivery of improved project outcomes. The empirical evidence further suggests that although the framework holds merit and is well received by project management professionals, its adoption would entail a significant cultural shift in organisations.

The paper aims to assess the dynamics that affects the retail rental outlets in a metro city considering the case of Mumbai, the commercial capital of India. The study uses a data set of shopping outlets in both shopping malls and stand-alone stores in this metro city. Regression and CART models are constructed to estimate the importance of the determinants and predict the rental values of the shopping outlets. The findings of the paper clearly indicate the significance of some of the determinants used in the study in predicting rental values. The results of the study would help builders, developers and investors to gain critical and empirical insights into the variables of the retail rent in any emerging real estate market.

This exploratory study examines which investing characteristics determine success in an equity market. Based on data from 403 respondents, exploratory factor analysis results in 13 factors: middle/long time horizon, qualitative analyst, open-minded/disciplined, organized, emotional stability, naïve, growth stock, concentrated portfolio, contrarian, value stock, globalized, intrinsic value, and price-independent. Multiple linear regression of individual investors' excess return on these factors show statistically significant relationship. These results deepen our knowledge on what sort of investing characteristics are required to survive in equity markets.

This paper provides various sensitivity analyses for the effects of the elicitation parameters of two methods for the utility function assessments needed to deal with risky decisions involving health state and consumption. The two methods include: a) Using a utility function over a deterministic value function, and b) Using a utility copula function over utility functions for each attribute. The two methods are explored and compared in terms of the derived Micromort value (a way to value a risky decision deal in dollars) and how it is sensitive to each parameter needed for the assessments of each method. The results show that the Micromort value increases with the consumption level and decreases with age. As the decision-maker increases the tradeoff between health and wealth, the Micromort value tends to increase. In addition, becoming highly risk averse over value, the decision-maker also has a higher Micromort value.

The rapid development of technology has driven the technology application in various sectors, including the application of Knowledge Management System (KMS). At the Maintenance Department of the XYZ Corporation, an aircraft manufacturing company in Indonesia, there is a potential of the tacit knowledge and experience of maintenance activity cannot be retained by the company when the employees enter retirement. Besides, the company did not have the system to manage tacit knowledge of the maintenance activity to enhance the performance of its employees. The purpose of this research is to design the KMS of the planning & control module to complement the KMS of maintenance activity that previously designed for the XYZ Corporation. The development of the KMS based on the waterfall method. The design of KMS features developed by using the KM Cycle. The KMS for maintenance activity integrates the enhanced features of the maintenance module and Knowledge Management module.

From our analysis of the situation within a manufacturing company in the metal-mechanical sector in Lima, Peru, we found problems due to the noncompliant products index. They originated mostly during the galvanizing process, for which analysis of the current situation was initially developed. To reduce nonconforming products, we designed and implemented a proposal using lean manufacturing tools. Then we validated the attainment of positive results compared to the initial situation. For example, we achieved a 6% reduction of nonconforming products, a 10% decrease in claims, a 6% reduction of reprocessing, and a 0.8% lower percentage of elimination.

This paper aims to investigate Chinese public's expectations of medical error disclosure, and to develop guidelines for hospitals. A national questionnaire survey was conducted in 2019, collecting 1,008 valid responses. Respondents' were asked their views of the severity of error they would like to be disclosed and what, when, where and who they preferred in an error disclosure. Results showed that Chinese public would like to be disclosed any error reached them even no harm. For both moderate and severe outcome errors, they preferred to be disclosed face-to-face, all the information as detail as possible, immediately after the error was recognized and in a prepared meeting room. Regarding attendance of patient side, disclosure was expected to be made to the patient and family. For hospital side, the healthcare provider who committed the error, his/her leader, patient safety manager and high-positioned person of the hospital were anticipated to be present. About the person to make the disclosure, respondents preferred the healthcare provider who committed the error in a moderate outcome case while the leader or high-positioned person in a severe case.
