Item MODELING AND ANALYSIS OF THE DRY PORT TRANSPORT LOGISTICS PERFORMANCE: A CASE OF MODJO DRY PORT(Hawassa University, 2023-10-13) HUNDUMA BERSISATo encourage the country’s economic development, import/export trade is a better and more cost-effective way are using dry ports. Dry Ports are the specific sites to which imports and exports can be consigned for inspection by customs and which can be specified as the origin or destination of goods in transit accompanied by documentation such as the combined transport bill of lading or multi-modal transport document. However, the management of trucks, loading and unloading time, processing of custom duties, port machinery productivity and dwelling time, etc. were the problems at MDP. the research problems in addition were delays at checking points, temporary storage and transport cost at inter-terminal. Therefore, this research was conducted with a model and analysis of Modjo dry port transport logistics performance to overcome the factor affecting the efficiency and effective of the transport logistics in the port. To overcome the problems, primary data collection methods (Site survey: observation, data record, questionary and interview) took place with the help of the company’s workers cooperation whose answers questionary properly 117 of 146 considered in the research. The secondary data source (Text books, articles, journals, theses, and company documents) was used for preliminary identifying the problems and validating the study after the results were analyzed. The raw data collected through different tools in the research were analyzed with the help of SPSS, Excel, and QM for windows software packages. The analyzed data was shown by percentage, mean, table, chart and graphs and the results were shown by graphical and mathematical models. After the results obtained were analyzed and discussed, the research questions; the model of the transport logistics performance, and the performance of its operations were answered. In these results, different performance indicators and their attributes were modeled from the existing model with modifications, in terms of checking points (in-gates) an additional in gate and two other reach stackers at temporary storage will be necessary to be assigned, and the terminal transports should be directly delivering the cargo through CFS to the customers for cost and time optimizationItem PERFORMANCE EVALUATION OF STORMWATER DRAINAGE SYSTEM OF BEDELE TOWN(Hawassa University, 2020-10-24) YEROSAN KEBEDE AYANAVarious factors can degrade the drainage system and reduces its performance. As the role of drainage infrastructure is very high in preventing urban floods, their performance should be monitored and quantified. This study aimed to assess the performance of stormwater drainage systems in Bedele Town. Primary and secondary data were used in this study. The catchment that contributes runoff was delineated using ArcGIS 10.4 software. The Stormwater Management Model (SWMM 5.1) was used to simulate the peak flow rate and water level in the drainage canals by considering the current land use. The intensity duration frequency (IDF) curve was developed by using the Log-Pearson Type III. The peak runoff for 10-year and 25-year return periods was estimated by using the Rational Method. The condition of the existing drainage system was assessed and poor solid waste management, lack of well-connected drainage lines, poor liquid waste disposal, and the existence of fully uncovered areas in the town with drainage structures were identified to be the drainage problem of the Town. From the total area of Bedele Town, 41.1% is uncovered with the drainage systems. The total peak runoff generated from this study area is 15.59 m3/s and the average velocity was 2.5m/s for a 10-year return period. The result from the Rational method as well as SWMM 5.1 shows there is an overflow problem in this study due to the presence of drainage canals with insufficient capacity to carry the runoff generated from this catchment. For a sustainable drainage system, the appropriate use of hydrological analysis, hydraulic design, and stream morphological study should be implemented before carrying out the construction of drainage structures for they were not considered during the construction of the drainage system of the Town. Regular maintenance and frequent clearance of drainage lines, proper integration between roads and drainage structures, provision of additional drainage canals, and improved stormwater management were recommended to solve the stormwater drainage problem of the TowItem Performance Evaluation of Ameleke and Halo-Gelana Small Scale Irrigation Schemes located in Gedeb and Wonago Woredas Gedeo Zone Southern Nations, Nationalities and people Region, Ethiopia(Hawassa University, 2020-04-06) NATNAEL ZEWDUThis study was conducted to evaluate the performance of Ameleke and Halo Gelana small scale irrigation schemes at Gedeo Zone, southern Ethiopia with command area of 42 ha and 75ha respectively. To achieve the objective primary and secondary data were collected. Ameleke and Halo Gelana irrigation schemes were compared using internal and external performance indicators. In order to evaluate the irrigation water use efficiency of farmers at field level, nine farmer fields were selected from each irrigation schemes in relation to their location (from the head, middle and tail end water users). The internal process indicators which include conveyance, application, storage, deep percolation ratio and overall irrigation efficiency were used to check the internal performance of the two irrigation schemes. From the analyses of the internal performance indicators, the mean conveyance efficiencies per 100m length at main canal were found to be 93.3 and 78% and application efficiencies were found to be 72.13 and 67.55% for Ameleke and Halo Gelana, respectively. The runoff ratio for both schemes was nil as the furrows are closed end type. Deep percolation ratios in the same order of the schemes were found to 28.20 and 32.45% for Ameleke and Halo Gelana. Storage efficiencies of 77.35 and 80.7% were also found for Ameleke and Halo Gelana irrigation schemes, respectively. From the analysis of external indicators, the outputs per cropped area were found as 2,852.77 and 2,179.41 US$ ha-1 for Ameleke and Halo Gelana irrigation schemes respectively, but the value of the outputs per command area of schemes were 2,852.77 and 1,278.59 US$ ha-1 for Ameleke and Halo Gelana irrigation schemes respectively. The output per unit irrigation supply of Ameleke is 0.17 and that of Halo Gelana is 0.13 US$ m-3 . Output per water consumed was 0.18 and 0.14 US$ m-3 for Ameleke and Halo Gelana irrigation schemes respectively. The water use performance of the two schemes were compared, relative water supply and relative irrigation supply were found as 1.06 and 1.07 Ameleke and Halo Gelana respectively. The irrigation ratio of Ameleke was found to be 1.00 which means 100% of command area was under irrigation and that of halo Gelana was 0.59 which means about 41% of command area is not under irrigation during study period. In general, based on the assessment carried out, Ameleke irrigation scheme performed better than Halo Gelana scheme. But there is still a room for improvement of the performance of both schemes specially on improving water delivery system, introducing high value crops and agricultural intensificationItem ASSESSMENT OF PERFORMANCE FOR PUBLIC BUILDING CONSTRUCTION PROJECTS IN HAWASSA CITY(Hawassa University, 2020-07-18) BITSIT BEKELE YUTURAConstruction industry has complexity in its nature because it contains large number of parties as clients, contractors, consultants, shareholders, regulatory bodies and others. In Hawassa the number of building projects is increasing from time to time. However, it has become difficult to complete projects in the allocated cost, time and quality. The aim of this thesis is to assess performance of public building construction projects in Hawassa city. Data collection techniques used included literature review, interviews and questionnaire surveys. As outcome 58 factors were identified as factor affecting performance of construction projects. The factors classified in to nine categories (cost, time, quality, productivity, client satisfaction, community and regulatory satisfaction, health and safety, innovation and learning and environment) related factors. For the analysis of the data, statistical analysis SPSS software is used. A survey finding confirmed that major factors that affecting performance has been escalation of material prices, material and equipment cost, availability of resources as planned through project duration, sequencing of work according to schedule, number of disputes between owner and project parties, cost of variation order, incomplete drawing and application of health and safety factors in organization. The main key performance indicators have been cost, time, quality and productivity. Finally based on the findings and results some recommendations were givenItem ANALYSIS OF THE EFFECTS OF THREE WHEELERS ON PERFORMANCE MEASUREMENT PARAMETERS OF INTERSECTIONS: A CASE STUDY: ROUNDABOUTS AND SIGNALIZED INTERSECTIONS IN HOSSANA CITY(Hawassa Unversity, 2020-10-18) DAWIT DAMISSIE ERGICHOTraffic intersections are complex locations on highways. This is because vehicles moving in different direction want to occupy same space at the same time. Traffic volume is one of the variables that have the biggest effect on intersection performances. The traffic volume of Menharya and Maryam signalized intersections, Bezabh Petros and Eyerusalem roundabouts at Hosanna city is highly occupied by three wheelers. So it is vital to study the effects of three wheelers on performance measurement parameters of intersections. The other purposes of the study were, analysis of existing intersection performances, evaluation of the consequences of three wheelers with performance parameters and comparing the performance change of intersections by replacing three wheelers with a minibus. All data were collected by using video camera for traffic data and measuring tape for geometric data. By taking peak hour volume, the performance measurement parameters of intersections were done using HCM 2010 methodologies incorporated in SIDRA Intersection Software 5.1. The effects of three wheelers on intersection performances were evaluated by excluding three wheelers from analysis and by comparing each performance parameter changes with and without three wheelers. By replacing three wheelers with minibus of 12 seats, the performance changes of intersections were evaluated and compared well. From the result of the study, Menharya signalized intersection is operating above its capacity because, the degree of saturation of this intersection is 1.374 which is greater than one and Maryam signalized intersection also shows congested condition with degree of saturation 0.852. 70.5% cause for delay, 85.5% cause for a degree of saturation, and 93.8% cause for the queue distance of Menharya signalized intersection is the presence of three wheelers. In the same manner for Maryam signalized intersection, 17.1% cause of delay. 82.2% cause of degree of saturation, and 90.7% cause of queue length is three wheeler's presence. The performances of both roundabouts are also affected highly due to presence of three wheelers. For Menharya signalized intersection, 54.1% Average delay, 31.7% degree of saturation and 59.5% queue distance, For Maryam signalized intersection, 19.3% Average delay, 32.4% degree of saturation and 45.6% queue distance is improved when Three wheelers replaced by minibus.Item ANALYSIS OF THE EFFECTS OF THREE WHEELERS ON PERFORMANCE MEASUREMENT PARAMETERS OF INTERSECTIONS: A CASE STUDY: ROUNDABOUTS AND SIGNALIZED INTERSECTIONS IN HOSSANA CITY(Hawassa Inversity, 2020-07-17) DAWIT DAMISSIE ERGICHOABSTRACT Traffic intersections are complex locations on highways.

It has a significant effect on social, economic, and environmental. Due to economic development and urbanization, transport in Addis Ababa has faced traffic congestion problems. This paper presents a study on the evaluation of operational performance of traffic in Addis Ababa in the case of the Megenagna to Ayat road network by addressing the factors that cause traffic congestions. LOS, average delay, and degree of saturation were quantified for three roundabouts using SIDRA software to analyze the traffic conditions in the study area. And Levels of service for three road segments were quantified using HCM 2010. A multiple regression analysis using SPSS was applied to quantify the factors that cause congestion on the performance of the road network based on questionnaire and field data. From the analysis, average speed of Ayat to Yetebaberute, Yetebaberute to Sahilitmiheret, Sahilitmiheret to Megenagna road segments were 11.6km/hr, 6.3km/hr & 5.45km/hr respectively and it was 30.08%, 26.14% & 22.59% of the free flow speed respectively. The LOS of these three road segments was F, and the traveler perception score was greater than 5, indicating drivers perceived the worst service. And for the three roundabouts i.e., Sahilitmiheret, Yetebaberute, and Ayat roundabouts, the overall LOS was F, so the degree of saturation is greater than 1 with the overall average delay of 405.20sec, 211sec and 310.2sec, respectively. The results from SIDRA software indicated that the roundabouts are providing traffic service above their capacity during the peak hour. From the SPSS result of the mean-variance results are significant at 0.05(p-0.05), which means that the factors caused traffic congestion in the study area. The regression model developed with R2 of 0.985, which is greater than 0.7, which shows the model was reliable. Based on the result of the study, the roundabouts were over congested; their operational characteristics were unsatisfactory, serving beyond their capacity & at a poor level of service. And the roundabouts contribute significant effect for the performance of the segments. The performance of the road network was poor and cause significant delay for the user. The factors that contribute for the poor traffic performance in the study area were significant to cause congestion.Item ASSESSING CRITICAL FACTORS AFFECTING THE PERFORMANCE OF ROAD CONSTRUCTION PROJECTS (A CASE OF ROAD PROJECTS IN SIDAMA ROADS AUTHORITY)(Hawassa University, 2025-07-14) ERDACHEW EYOB SIMEThe Construction Industry is one of the very fast-growing industries but it also faces many problems which impinge on the performance of their projects. For this reason, it is necessary to plan these projects properly to guarantee their success. The study was conducted with the objective of identifying critical factors affecting the performance of road construction projects in Sidama Roads Authority, developing a framework to improve the performance of road construction projects in SRA and giving suggestion and recommendation to mend the performance of road construction projects in SRA. The study adopted a descriptive research design. Mixed research approach was also employed in this study. A relevant literature was reviewed and self-administered questionnaire which contain A total of 54 performance factors with seven factor groups categorization. It was designed to collect relevant information from purposively selected 120 respondents of SRA (Bensa Daayye road district). Study population was pre-selected twenty (20) road construction projects which found in six road clusters of Bensa Daayye road districts. Additionally; Data were gathered through Focus discussion group. collected data was coded and entered into statistical packages for Social Scientists SPSS Version (27) and analyzed using descriptive statistics such as percentage, frequency and relative importance index (RII) was used to rank the identified factors. The findings were presented in form of tables while explanation was presented in prose and the findings revealed seventeen most significant factors that significantly affects the performance of road construction projects in selected twenty road construction projects in SRA those factors. Those factors were the main causes for the delay and cost overrun. Thus, the output of this research will contribute to identify and understand the critical factors affecting the performance of road construction projects in SRA, by providing fully enough information to identify the areas where necessary action needs to be taken and by furtherly providing respective suggestion, recommendation and subjective framework to improve performance of road construction projects. In addition, it is recommended to Moreover, in addition to the studied critical factors, further in-depth investigation is recommended on many unaddressed critical factorsItem ASSESING PERFORMANCE EVALUATION PRACTICE OF BUILDING CONSTRUCTION PROJECT IN HAWASSA CITY(Hawassa University, 2021-03-18) BIRUK KEBEDE BEKELEProject performance has been considered to be tied to project success and this is also tied to project objectives. Based on this to evaluate performance effectively and efficiently we should develop an objective and consistent measurable criteria. These criteria are called performance dimensions. According to many study performance dimension has been encounter performance shortfall in construction industry worldwide and in developing country at large. Especially in Ethiopia and the city Hawassa the problem is clearly shows. The research aimed at assessing the performance evaluation practice on four Dimensions namely Time, Cost, Quality and health and safety and its challenges and also develops a framework to efficiently practice performance evaluation in construction project in Hawassa city. The study adopts both quantitative and qualitative approach to assess the performance evaluation practice in Hawassa city. Simple random samplings were used to select the representative sample form entire population. Quantitative approach used questionnaire while qualitative approach uses semi-structure interview and case study to stimulate the relevant response from the major stakeholders in the Hawassa building construction project. The data collected by questionnaire were analyzed using frequency and mean for objective one and one sample t-test for objective two. In doing so The study concludes most contractors has limited budget set for evaluation purpose, most contractor evaluate their project in every phase of project. And most contractor use “time variation” formula to measure time, percent net variation over final cost formula to measure cost, system quality method to measure quality, fatality rate to measure safety. The study found that, limited financial resource, poor quality of data collected, poor communication, lack of monitoring and evaluation plans in planning, and budgeting, weak legal and institutional framework and Poor demand for monitoring and evaluation. Lack of monitoring and evaluation units within the organization and Weak linkage between planning and evaluation are the most challenges in Hawassa construction project. And all projects never use the most common framework like Balance score card, European foundation for quality management, Key Performance Indicator and Earned Value Management. Finally the research recommends that contractors in Hawassa should allocate budget, use reliable framework and organize independent unit for performance evaluation. The study develops performance evaluation framework helps to project success and uses as benchmark for other study in Hawassa citItem MODELING AND ANALYSIS OF THE DRY PORT TRANSPORT LOGISTICS PERFORMANCE: A CASE OF MODJO DRY PORT(Hawassa University, 2023-08-06) HUNDUMA BERSISATo encourage the country’s economic development, import/export trade is a better and more cost-effective way are using dry ports.
