    (Addis Ababa University, 2024) Biruk Gebremedhine; Ameha Mulugeta (PhD); Ayele Legesse (Mr.) Co-Advisor
    The research aims to develop a decision support system (DSS) for spare parts inventory management in order to reduce maintenance costs at Sunshine Construction Company. The study employs a well-designed approach, incorporating data analysis techniques and leveraging DSS systems to gain insights for optimizing inventory management and reducing repair costs. The literature review examines inventory management in the construction industry, focusing on areas like optimizing stock levels, lead-time, decision support systems, maintenance, and repair cost control. It explores strategies such as (s, S) and (q, r) policies, modern inventory management technologies, and the importance of collaboration among stakeholders. A critical issue identified in the review is the need to address the challenge of inaccurate demand forecasting, which can significantly impact inventory optimization efforts. The data collection and analysis used both quantitative data from a case company concerned department recording data like inventory levels, repair costs, maintenance costs) and qualitative data (through interviews). Tools like Excel, FMEA, and the EOQ model are used to analyze and optimize factors like stock levels, lead times, reorder quantities, and safety stock. The expected findings and recommendations aim to improve inventory performance, reduce costs, and promote business success in spare parts management at Sunshine Construction Company. The study aims to contribute innovative solutions related to demand forecasting, inventory policies, maintenance cost control, and technology integration

    Predicting and Analyzing the Impact of Occupational Safety& Health on Labor Productivity: A Case of Ethiopia Plastic Industry
    (Addis Ababa University, 2024-10) Feleke Workie; Kassu Jilcha (Assoc. Prof.); Ayele Legesse (Mr.) Co-Advisor
    Back ground: the Ethiopian plastic industry occupational health and safety risks are negatively impact labours motivations and output. While the information of Ethiopian plastic industry occupational health and safety, such as a review of situational analysis and needs assessment and the impact of energy use on labour productivity in the industry, specially address how to predict or look into the relationship between worker productivity and OHS in Ethiopia plastic industry out of 396 employees of 70 target labours are take all. Objective: In order to create mitigation plans for preventive and corrective measures, the objective is to forecast and analyze the impact of OHS on labour productivity in EPI. Methods: the following techniques to be used to predict and assess how OHS would affect worker productivity in Ethiopia plastic industry. review of relevant literature: analyse the corpus of work on occupational health and safety in multinational industrial enterprises, with a focus on the plastic industry. This to give insight on the possibility, challenges, and state of the industry’s OHS protocols. Gatherings of data: gathering pertinent information on worker productivity, OHS metrics, and other Ethiopian plastic industry component. This data to be gathered through unstructured interview, primary and secondary data sources, and surveys, and then analysed the integration of all that are regression analysis and correlation analysis. Purpose: The aim of this study was to determine how worker productivity in Ethiopia plastic industries was affected by occupational safety and health. Results and discussion: According to the study's findings, the majority of workers are aware of how workplace safety and health affect labours productivity. Furthermore, the survey discovered that even though workers are aware of the risks to their health and safety at work, they often forget to wear personal protective equipment because they think it's too hot. The study comes to the conclusion that worker productivity is strongly impacted by occupational health and safety. In order to reduce workplace accidents and injuries, this study advises management to protect employees and supply them with personal protective equipment. In order to reduce workplace accidents and increase productivity, the study also suggests that management provide routine training and education on occupational health and safety issue.
