Abstract
The automotive industry provides multiple model versions to accommodate consumers' varied needs and tastes. Considering the intricate nature of the model variants, one OEM allocated the resources of quality systems to ensure the integrity of the vehicles provided to consumers. Notwithstanding the established quality management processes in automotive manufacturing, incorrect components can be installed in fully assembled vehicles. These issues are evident in the quality statistics and expenses associated with scrap and rework for the organization under examination. This study aimed to evaluate the effectiveness of the existing system and propose an appropriate human-machine interface to enhance the current systems.
In this study, we employed a structured research methodology and literature review to direct the investigation. The methodology was developed using Saunders research onion. Each layer of methodology was analysed from the philosophical outer layer to the inner core practicalities of data collection and analysis. The literature review enabled the research to acquire contemporary knowledge in the application of HMIs and traceability technology, along with its bounds and limitations. A systems evaluation was conducted to assess the implementation of HMI and identify areas for potential enhancement. The High Capability tools (HCT) and the Pick-to-Light (PTL) systems were the two evaluated systems. The evaluation brought into perspective the benefits and shortcomings of both systems.
The results derived from the system evaluation were validated using a survey distributed to 46 persons familiar with the existing quality systems. Despite the predominant satisfaction among system users, they commented on the existing issues with the systems. The primary concerns regarding the PTL and HCT systems were their speed and the absence of essential functionality. One of the findings of the survey shows inconsistency with respondents being happy with the system yet having issues. However, according to the survey, the resolution to the problem of system speed is to enhance software systems and tools. The proposed remedy for the 'absence of essential features' is to integrate virtual reality within the production environment, according to the survey. The incorporation of virtual reality may reduce the incidence of improper component fitment by providing a reference system.
