    Assessment of Warehouse Operations Based on Essential Performance Optimizing Components Among Private Pharmaceuticals Importers in Addis Ababa
    (Addis Ababa University, 2024-06) Samuel Tadesse; Matiwos Ensermu (PhD)
    This study evaluates warehouse performance optimization among private pharmaceuticalimporters in Addis Ababa. Utilizing a descriptive study design with a mixed research approach, data were collected from 52 private pharmaceutical importing companies through structuredquestionnaires and personal evaluations. The data were analyzed using descriptive statistics and Kendall’s W Test, with results presented in tables.The analysis revealed that essential components for optimal warehouse performance include infrastructure and planning. Key factors such as the condition of the ceiling, walls, floor,cleanliness, ventilation, lighting, protection from rodents and insects, and maintained temperatures were identified as crucial. Additionally, the layout and operational efficiency,including separate receiving and dispatch areas, secured receipt areas, designated spaces for expired and damaged products, and sufficient aisle space, were highlighted as vital.Warehouse equipment, such as the presence of pallets, pallet jacks, and operable fork trucks, also contributed to optimized operations. Special storage requirements, including a cold chainsystem, properly operating refrigerators, solar-powered refrigerators, and designated areas for hazardous and flammable materials, were noted as important for performance optimization.Inventory management emerged as a crucial component for performance optimization. Key practices include maintaining electronic and paper inventory records, ledgers, periodic physicalinventory counts, FEFO (First Expired, First Out) distribution systems, and the proper disposal of expired and damaged products. Security and safety, along with effective human resourcemanagement—responsible management, staff training, job description postings, SOP postings, orientation for new hires, and sufficient capacity—were also identified as essential foroptimizing warehouse performance. Key terms: Pharmaceuticals, Warehouse, Performance, Optimization

    Economic Impacts and Challenges of Parking System in Addis Ababa City, Ethiopia: Evidence from Addisu Gebeya to Qidus Giorgies Church Corridor
    (Addis Ababa University, 2026-06-01) Samuel Tadesse; Dagnachew Adugna
    Unmanaged parking in rapidly motorizing African cities generates compounding economic, mobility, and governance costs. In Addis Ababa, formal parking supply meets fewer than 40 percent of commercial corridor demand, yet corridor-specific empirical evidence linking parking system failures to measurable economic impacts remains absent from the literature. The study assessed parking supply adequacy and spatial distribution, evaluated parking management effectiveness and institutional coordination, and identified the economic im pacts of the existing parking system along the Addisu Gebeya-Qidus Giorgis Church corri dor, Arada and Gulele Sub-city. sequential explanatory mixed-methods design was em ployed. Data were collected from 180 questionnaire respondents across six stakeholder groups, supplemented by key informant interviews (n = 12), focus group discussions (n = 3), a parking inventory and occupancy survey, travel time delay measurements, and GIS spatial analysis. Analytical techniques included descriptive statistics, one-way ANOVA with Tukey HSD post-hoc tests, and binary logistic regression. Formal parking supply met less than 25 percent of peak demand, with occupancy reaching 94 percent during peak periods. Binary logistic regression identified parking inadequacy (OR = 2.51), fee avoidance (OR = 2.03), and congestion perception (OR = 1.79) as significant predictors of illegal parking. Peak hour travel times exceeded free-flow conditions by 177 percent, generating an estimated an nual delay cost of 1,910 ETB per commuter. Over 83 percent of business owners reported parking-related business constraints, and institutional fragmentation across three agencies was the principal governance barrier.Parking system failure on the corridor is driven by structural supply inadequacy, governance fragmentation, and absent demand management mechanisms, collectively imposing significant economic and accessibility costs on all corri dor users vidence-based interventions are required, including a Corridor Parking Coordi nation Committee, multi-story off-street parking, occupancy-responsive pricing, shared parking districts, and parking by-law reform. The mixed-methods corridor-level framework developed here is replicable across high-intensity urban corridors in the Global South.

    Multi-tiered Amicable Construction Dispute Resolution in Addis Ababa: Legal and Institutional Dimensions.
    (AAU, 2023-03-16) Samuel Tadesse; Aschalew Ashagre(PhD)
    The construction sector has a significant impact on the growth of a state, either directly or indirectly. Since the growth of infrastructure is crucial for Ethiopia. However, due to the numerous players in the market which makes things complicated, disagreements are frequent and often unavoidable. So, it needs to use dispute resolution procedures properly. Globally, strategies of dispute prevention and amicable dispute settlement are strongly advised as being a more efficient way to resolve disagreements. One of the most productive ways to resolve a disagreement amicably is by using each multi-peaceful tier technique step-by-step and employing a variety of amicable tools are efficient. Therefore, the goal of this study is to analyze the legal framework and institutional practice of amicable dispute settlement via multi-tier mechanisms in Ethiopia, particularly in the Addis Ababa construction industry. Further, the study adopted a qualitative research design. Both doctrinal and empirical approaches were employed in data collection. However, multi-stage peaceful conflict settlement mechanisms, such as med-arb and mini-trials, are uncommon in the construction industry. Furthermore, disputants rarely settle disputes using multi-tier amicable resolution processes. Consequently, developing a thorough legislative framework, guidelines and procedures, raising awareness, and introducing institution centres that serve both the nation and the rest of the world suggested a major recommendation.
