User-Requirements Analysis on Augmented Reality-based Maintenance in Manufacturing

Maintenance of technical equipment in manufacturing is inevitable for sustained productivity with minimal downtimes. Elimination of unscheduled interruptions as well as real-time monitoring of equipment health can potentially benefit from adopting augmented reality (AR) technology. How best to employ this technology in maintenance demands a fundamental comprehension of user requirements for production planners. Despite augmented reality applications being developed to assist various manufacturing operations, no previous study has examined how these user requirements in maintenance have been fulfilled and the potential opportunities that exist for further development. Reviews on maintenance have been general on all industrial fields rather than focusing on a specific industry. In this regard, a systematic literature review was performed on previous studies on augmented reality applications in the maintenance of manufacturing entities from 2017 to 2021. Specifically, the review examines how user requirements have been addressed by these studies and identifies gaps for future research. The user requirements are drawn from the challenges encountered during AR-based maintenance in manufacturing following a similar approach to usability engineering methodologies. The needs are identified as ergonomics, communication, situational awareness, intelligence sources, feedback, safety, motivation, and performance assessment. Contributing factors to those needs are cross-tabulated with the requirements and their results presented as trends, prior to drawing insights and providing possible future suggestions for the made observations.

The role of management accounting in the development of supply chain performance in logistics manufacturing companies

The supply chain has been a major component of competitive strategy to enhance organizational productivity and profitability, and the supply chain is a relatively new and rapidly expanding discipline that is transforming the way that manufacturing and non-manufacturing operations meet the needs of their customers. This study aims to establish the role of management accounting in the development of supply chain performance in logistics manufacturing companies. The study applies a quantitative research methodology and uses a questionnaire method to collect the data. The study sample consists of 181 respondents. This study analyzes the data using the (SPSS) program. The results reveal a statistically significant relationship at the significance level (α≤0.05) between the management accounting, including the “target cost, value chain costing and quality costing” and supply chain performance in logistics manufacturing companies.

LabVIEW Based Inventory Management System

The aim of this paper represents the “LABVIEW BASED INVENTORY MANAGEMENT SYSTEM” creates a web-based producing system that permits manufacturing business to schedule its manufacturing operations supported the daily update of sales from its dealers. Once the sales figure of things for the past weeks are entered by the dealers over the net alongside the orders for future delivery, the schedule for future week’s production is immersed. A report of the specified raw materials or components are immersed with the merchandise necessities over the net & asked to quote their rates. Once the rates are quoted, the order is placed with the specified delivery schedules. Once the components are equipped the stocks are updated. Then a production arrangement is immersed considering the bill of materials. Once the assembly arrangement is approved, the stock is updated once the fabric is issued. Once the finished merchandise are on the market the delivery schedules are immersed supported the orders placed by the Dealers. The stocks with the dealers also will be maintained.

CONTACT INTERACTION OF A TORSION SHAFT WITH A SPLINED BUSH IN ELASTICALLY PLASTIC DEFORMATIONS

Torsion shafts are the main elastic element of the suspension systems of a large number of vehicles. To simulate their reaction to the action of torque, the stress-strain state is analyzed taking into account the contact interaction with the spline sleeve. The features of the distribution of contact pressure between these bodies are established. The nature of stress concentration in the splined hollows of the shaft head is determined. Models and research methods have been developed that make it possible to develop recommendations for design decisions in the design of vehicle suspension systems. The factors are determined that ensure the strength of the torsion shaft at the values of its head diameters close to the diameters of the torsion shaft stem. In the case under consideration, this factor is firstly strength of the torsion shaft head. In particular, it was found that during manufacturing operations there are significant plastic deformations and contact loads in the heads of torsion shafts. This factor is decisive in substantiating the design parameters of torsion shafts. Keywords: torsion shaft; contact interaction; stress-strain state; elastically plastic deformation; suspension system

The 2011 Bangkok Floods: Live Peacefully (Yoo Hai Yen), Live Harmoniously (Yoo Hai Pen Suk)

<p>Thailand’s Bangkok has experienced rapid population growth and subsequent expansion over recent decades. It has resulted in an unintentional increase in vulnerability within rural-residential and metropolis areas. Flood prevention strategies, such as dams, irrigation canals, and flood detention basin, and Kaem Ling ‘Green belt Embankment’, have been slowly built and activated in response to this suburban catastrophe (Vanno). In recent years, King Rama IX of Thailand, initiated Kaem Ling’s, ‘Monkey’s Cheek’s’ project; a reference to the common parable of an intelligent monkey storing its food in its saggy cheeks rather than swallowing. This has allowed the Western and Eastern suburbs of Bangkok to function as waterways, diverting the destructive water paths away to protect the metropolis. Beginning in July 2011, a significant rainfall from the highlands of Thailand flooded down to Bangkok. With affected areas lying less than 10 metres above mean sea level and some as low as 1.5 metres, some areas remained flooded until January 2012. By October, the inundated metropolitan Bangkok began to negatively impact on industries, such as computers and automotive. Both critical supply networks for other manufacturing operations outside of Thailand. This ‘vulnerability’ where the inter-connectedness of economies could mean the closing of factories and manufacturing assembly lines in one country because of a flooding disaster in another had not been recognised. The 2011 Thailand’s flooding death tolls surpassed 815 deaths (with 3 missing), affected 13.6 million people and classed 65 of Thailand’s 77 provinces as flood disaster zones (Benfield, 2012). During the extreme environmental activity, decisions were made to close several district gates in last-ditch efforts for protecting the metropolitan areas. This caused many other peri-urban areas of Bangkok to flood. These suburban areas were intended to act as waterways to protect the metropolis, but instead became a reservoir. Nimitmai 40 Road, situated in Khlong Sam Wa district, was in the middle of the 2011 flooding zones became the locus and main area of interest in this research. Several initial studies, of precedence and technical data, explored objectives of building resilience in response to flooding and community. This research further utilised field study surveys, interviews, and case studies, all of which provided a wealth of information and contextual material. They contributed to design propositions developed through a series of critical reflections. This research aimed to build community resilience, encapsulating spiritual elements in cultural and psychosocial elements of suburban Thai community’s livelihood and to provide flood resilience through both non-technical and technical solutions. Final outcomes of the design iterations suggested a merging of Thai monastery and community centre as a spiritual anchor for the community’s resilience and strengthen my neighbourhood’s sense of place.</p>
