Assessing Materials Management Practices Effect on Firm’s Performance in Ghana Using Dominance Analysis: Evidence from a Listed Company

The objective of this study is to empirically examine the effect of materials management on a firm’s performance by exploring employee views and utilizing a firm’s financial statement data within the Ghanaian context, focusing on Fan Milk Limited, a listed manufacturing firm in Ghana. A cross-sectional research design was espoused for the study, utilizing questionnaires completed by 240 respondents selected via simple random sampling. SPSS version 25.0 was utilized for data analysis, which included descriptive statistics, principal component analysis, exploratory factor analysis with varimax rotation, reliability/validity analysis, and multivariate regression aided with relative importance analysis via dominance analysis. The study found significant positive relationships between all eight materials management practices and a firm’s performance. Dominance analysis further revealed that materials requirement planning and control was the most important predictor of a firm’s performance, while ergonomics was the least important predictor of performance. Managerial recommendations established should be viewed critically while managing manufacturing firms.

Safe Transportation of Nuclear Fuel Assemblies by Means of Wheeled Robotic Platforms

Certain engineering problems concerning safety of the technological operations of the horizontal transportation of nuclear fuel within the enterprises’ sites were considered. Taking into account current trends in the introduction of robotic systems to reduce the impact of hazardous nuclear materials on personnel, the issue of automated control of the movement of the wheeled robotic platform, which can be used for horizontal transportation of nuclear fuel was studied. The major attention was paid to minimizing the transportation loads on nuclear fuel by means of decreasing the accelerations under its horizontal movement on the robotic wheeled transportation platform, which is a separate issue of the comprehensive safety problem of nuclear materials management. The research of horizontal movement safety of nuclear fuel by means of the robotic wheeled platforms was limited to defining transportation accelerations and was performed by computer simulations using mathematical models of dynamics and electro-mechanics. The mathematical model of the robotic transport wheeled platform loaded with nuclear fuel with the on-board accelerometer ensuring the required measurements necessary for an automated safe movement control system was built in the form of the Lagrange equations of the second kind and the electro-mechanics equations of the direct current electric motors. The issue of ensuring smooth running during the displacement of a wheeled platform loaded with nuclear fuel was investigated, since especially in this mode the maximum accelerations are observed, which can lead to nuclear fuel damage. Computer simulation was performed using free Scilab software with open program code. It was demonstrated that due to the proper choice of the time algorithm of the voltage of electric motors, it is possible to ensure a small acceleration during the displacement of a robotic wheeled transport platform loaded with nuclear fuel. The obtained result substantiated the possibility of safe horizontal transportation of nuclear fuel on robotic wheeled platforms within the territories of enterprises, which will significantly reduce the harmful impact of hazardous nuclear materials on industrial personnel.

GESTÃO DE ESTOQUE: REVISÃO DE LITERATURA DA UTILIZAÇÃO DA METODOLOGIA JUST IN TIME COMO DIFERENCIAL COMPETITIVO

This paper presents a literature review of the use of the Just in Time methodology as a competitive differential in companies that seek to control and manage their stocks using this tool. The Just in Time philosophy has undergone several changes throughout its development process by Toyota Motor Company. The first concept was to increase profits. To do so would have to increase the selling price. Thinking about market competitiveness this reasoning would not hold for long and was soon rethought to something more logical and that could please customers in business. Coming to the conclusion that minimizing costs would increase profits. The first surveys pointed the direction from where to begin modifications in the production process, which would be in improving the flow. From this observation began the Just in Time production system that proposes: zero inventory, reduced process time, quality, production on demand, eliminate losses and defects, automate processes and identify standardized operations. The objective research goes through book searches referring to inventory management, materials management, production planning and control among others described in the references. Thus, the work studied the emergence and evolution of the Just in Time methodology and its evolution the advantages and disadvantages of implementation and the understanding of pull production

VCS#9. Unapproved Materials From Approved Suppliers

This case study describes an abrupt and unexpected technical manufacturing problem caused by changes in the physical properties of a formulation ingredient. Manufacturing of a validated process could not be accomplished despite recently completed successful validation. Investigation determined a technical root cause, and also identified problems with practices in several site function areas. Practices in the site Materials Management function were significant in this event. Not all pharma personnel understand that materials from an approved supplier may not be universally acceptable in manufacturing – validation problems may have unlikely sources.

Analisis Pemasaran Kayu Hutan Rakyat di Kabupaten Bogor

The private forest is one of alternatives that played an important role in fulfillment of a need raw materials management industry wood and the needs of wood. Development of private forest can improve the people and land revenue increase productivity. Research conducted in sub-district Leuwisadeng, Cigudeg, and Jasinga shows that there are some marketing actors involved in marketing wood of the private forest of them are farmers, traders, and sawmill industries. The marketing of the three actors formed four marketing channels are grouped based marketing actors and average skidding distance. Channels that most efficient among fourth the channels is a channels II with the percentage of farmer’s share as 46.93 % and the ratio of K/B by 5.45. Types of plants most favored by farmers and consumers is the type of sengon it because sengon having a short, the age of harvest readily grows, and easy cultivation. The consumer likes kind of plant is because sengon have reachable prices, sengon not easily bad condition wood and widely available in market. Key words: bogor, farmer’s share, marketing efficiency rasio, private forest

Managing Contamination and Diverse Bacterial Loads in 16S rRNA Deep Sequencing of Clinical Samples: Implications of the Law of Small Numbers

There has been a gradual increase in 16S deep sequencing studies on infectious disease materials. Management of bacterial DNA contamination is a major challenge in such diagnostics, particularly in low biomass samples.

The Structural of Effective Materials Management Factors Model: A PLS-SEM Approach

Effective materials management has a significant role in the success of any construction projects. Understanding the factors related to the management effectiveness may assist the decision-makers of construction firms to allocate resources in the best possible manner in managing materials when implementing construction projects. However, limited studies have explored and investigated the associated factors of effective materials management related to project performance, especially in the Malaysian construction industry context. Thus, this research paper aims to investigate the influential factors of effective materials management and their effects on project performance. A partial least square-structural equation modelling (PLS-SEM) approach was employed to analyse 202 pieces of data collected from a questionnaire survey. The results indicate that the effective materials management has a positive significant impact on project performance. The top three groups of factors that contribute to this management effectiveness are transportation, management, and purchasing; meanwhile, the most implied factors of the effective materials management are waste, cost and time of project performance. To increase project performance, more resources should be allocated to improve the transportation, management and purchasing components of materials management.
