The purpose of the study is to identify existing gaps on workplace safety and health management and propose future research areas. The review adds value to existing electronic database through integration of researches' results. To identify existing gaps, a systematic literature review approach has been used. The reviews were undertaken through keywords and safety related topics. In the literature, various characteristics of workplace safety and health problems were found emanating from the lack of operational activities of the employees, internal working environment and external environment those impose hazards on employee temporarily, permanently and on working environments. The integration of multidisciplinary approaches and collaborative model of hub and peripheral industries to protect workplace safety hazards to develop multilevel model has been undermined in many researches. The other face of fin...

Thus, the purpose of this research is to minimize and analyze the loan processing cycle time of Development Bank of Ethiopia so that processing cycle time gets crushed. Project owners get frustrated when their loan application takes longer processing time. As the loan processing cycle time gets longer and longer, project owners or promoters lose enormous amount of money and energy waiting for the loan approval day. Thus, the study was conducted to improve this delay of loan processing time using data from the Bank and ARENA simulation software. In modeling this system, an ARENA software simulation model was developed, verified, and validated to determine the daily loan processing cycle time and potential problem areas for the various request levels in the case company to shorten the length of processing time. The ARENA simulation software used to...

The case study was done using both qualitative and quantitative approaches which could be said mixed approach. First of all, data collection has been conducted by actual presence in the case company. The data were collected using the check sheet. The team has collected the two months data from the case company. After adequate statistical data was collected, the team had used Microsoft excel and excel add on software to analyze the data using statistical quality control tools. The level of quality expectation of the products within the international customers are high, however the case company, the quality control system is not as strong as it is supposed to be. The company is n...

To achieve the planned production volume, a company needs to establish an optimal production sequences. A household utensils manufacturer in Ethiopia was our case company to investigate. We have studied the production sequence of a flat cooking pan, where one packed set of a flat cooking pan comprises seven diametrically ordered flat cook pans. Three production scenarios were developed based on the production line constraints of the case company. Among the various flow shop scheduling heuristics, Campbell, Dudek and Smith (CDC), and Nawaz, Enscor and Ham (NEH) methods were applied. In all production scenarios the applied heuristics yields an optimal production sequences with considerable reduction of a makespan. The optimal production sequences improved the annually planned production volume by more than 22%. Moreover, the paper discusses the performance of the applied heuristics.

Peacock shoe is one of the manufacturing industries in Ethiopia facing challenges on sustaining. The methodology followed is factor analysis and empirically testing hypothesis. A database was designed using SPSS version 20. The survey was validated using statistical validation using the Cronbach alpha index; the result is 0.908. The KMO index value was obtained for the 32 items and had a value of 0.642 with Bartlett's Test of Sphericity Approx. Chi-Square 4503.007, degree of freedom 496 and significance value 0.000. A factor analysis by principal components and varimax rotation was applied for finding the critical success factors. Finding designates that 32 items were merged into eight critical success factors. All the eight factors together explain for 76.941 % of the variance. Multiple regression model analysis has indicated that some of the critical success factors had relationship with success indicators. Due to constraint of time, the researcher focused only at peacock shoe manufacturing industry. Other limitation also includes the absence of any local research that shows the critical success factors at the moment.

Studies on the comparative advantages, preconditions, and contextual factors of implementing QFD revealed that firms comparatively improved quality of products, minimized costs, and shortened product development time as the result of introduction of the QFD to their system of operation. Studies in the context of Ethiopia also revealed that QFD has not been well introduced to the Ethiopian industries; as the result, they are incapable of competing with other industries in the local and global markets, and have faced problems related to cost and quality of products. Therefore, this paper argues that QFD knowledge transfer to developing countries, in general, and to Ethiopian industries, in particular, yields advantages to alleviate the problems related to cost and quality. Preconditions such as top management support,...

The method used was lean- six- sigma elements to define measure and improve unwanted process company wastes. In other word, Baldrige with six-sigma were created to define, measure and improve management perspectives. The tasks were integrated using both quantitative and qualitative analyzing tools implementing mixed strategies. The result was improved by using FMEA analysis was carried out at each stage of the existing process used to determine the failure of the process and to analyses and improve the production quality. The SPSS software was also used. In the finding section, the correlation and regression analysis has shown that there is strong relationship between each variance. There are different wastes that identified in six sigma (DMAIC) on NAS food Plc as a result; the value of waste ratio indicated is 36.7%. This show...

Improvement tools, like total quality management, have become prevalent terms in the discussion around quality issues. The intention of this paper is to study total quality management (TQM) implementation in Leather Industry Development Institute (LIDI), and more specifically, to see if the integration of TQM with other tools and techniques could significantly improve the service level of the institute and the satisfaction of the customers. The paper specifically highlighted that the role of senior managers in TQM implementation were minimal due lack of TQM awareness and system integration. To improve this, a phase-based TQM framework has been developed and interpreted comprehensively including implementation strategies, possible improvements and integrations. Due to this, the institute was expected to be passionate with regard to TQM and continuous improvement.

The objective of this article is also to understand the concept of lean manufacturing, its philosophy, various tools and techniques, lean implementation benefits and barrier towards lean implementation of chemical industries. Competitiveness of chemical manufacturing industry is not easily attainable since chemical products nature is variant. There are challenges which hinder the development of chemical industries production. The chemical industries contribution to the economy is very small when compared to agriculture contribution due to infant stage of the industrial group in general. The methods that can bring the chemical industries development and increase competitiveness is one lean thinking revolution. This lean isn’t just about using tools, or changing a few steps in chemical manufacturing processes. It’s about the complete change ...
