Humanitarian Logistics and Emergency Response in Humanitarian Organizations in Kenya. 肯尼亚人道主义组织的人道主义后勤和应急工作。
Chrisantos Kimori Osumo, Jane Queen Omwenga
Disasters were unpredictable and unavoidable, necessitating adequate disaster response plans. Humanitarian logistics, which gained prominence after the 2004 Asian tsunami, played an important part in crisis prevention. Despite weak links in relief chain management, issues remained. Humanitarian logistics had a huge impact on disaster relief efforts, as studies revealed a variety of challenges, including a lack of sufficient SCM software and poor facilities. Despite its importance, few studies have explored the impact of disaster assistance on humanitarian organizations, particularly in Kenya. The study sought to address this gap by evaluating the impact of humanitarian logistics on emergency response in Nairobi, Kenya. Humanitarian groups, policymakers, and NGOs profited from the research, which informed strategic planning and policy creation to strengthen disaster response operations. The Resource Dependency Theory (RDT) proposed that organizations rely on external resources for survival and growth. It underlined the importance of forming strategic alliances to secure resources. In humanitarian settings, logistics were critical in procuring and allocating resources for successful emergency response. The research methodology used a cross-sectional descriptive design to investigate the association between humanitarian logistics management techniques and emergency response in Kenyan humanitarian organizations. Semi-structured questionnaires were used to obtain data from 64 Nairobi-based firms. Data analysis required the use of both descriptive and inferential statistical techniques, such as regression and correlation analysis. The study found a significant positive association (β = 0.732, p < 0.001) between logistics management practices and emergency response, indicating that improving logistics leads to better response outcomes. The study recommended prioritizing logistical development and resource allocation to improve emergency response capabilities.
灾害是不可预测和不可避免的,因此必须制定适当的救灾计划。人道主义物流在 2004 年亚洲海啸之后得到了重视,在预防危机方面发挥了重要作用。尽管救灾链管理存在薄弱环节,但问题依然存在。人道主义物流对救灾工作产生了巨大影响,研究揭示了各种挑战,包括缺乏足够的供应链管理软件和设施落后。尽管其重要性不言而喻,但很少有研究探讨灾害援助对人道主义组织的影响,尤其是在肯尼亚。本研究试图通过评估人道主义物流对肯尼亚内罗毕应急响应的影响来弥补这一不足。人道主义团体、政策制定者和非政府组织从研究中获益匪浅,为加强救灾行动的战略规划和政策制定提供了依据。资源依赖理论(RDT)提出,组织的生存和发展依赖于外部资源。该理论强调了结成战略联盟以确保资源的重要性。在人道主义环境中,物流对于采购和分配资源以成功开展应急响应至关重要。研究方法采用了横截面描述性设计,以调查肯尼亚人道主义组织中人道主义后勤管理技术与应急响应之间的关联。研究人员使用半结构式问卷从 64 家内罗毕公司获取数据。数据分析需要使用描述性和推论性统计技术,如回归分析和相关分析。研究发现,物流管理实践与应急响应之间存在明显的正相关关系(β = 0.732,p < 0.001),表明改善物流会带来更好的响应结果。研究建议优先考虑后勤发展和资源分配,以提高应急能力。

Performance Measurement Integration And Performance Of Manufacturing Firms in Rwanda 卢旺达制造业企业的绩效衡量整合与绩效
Alexis Uwamahoro, N. Shale, E. Wachiuri
Rwanda's manufacturing industry is essential to the country's economic growth and employment generation. Achieving sustainable development and global competitiveness necessitates the integration of performance assessment effectively. This entails measuring and optimizing organizational performance, especially in supply chains, using a variety of measures. Global market trends and resource limitations are two ongoing challenges that emphasize the necessity for reliable measuring methods. In order to give policymakers and business practitioners useful information, this study aims to assess the effect of performance measurement integration on manufacturing company performance in Rwanda, concentrating on important industries and geographical areas. Expectancy Theory and the Balanced Scorecard Framework (BSC), two important theoretical frameworks related to performance measurement integration in manufacturing businesses, are examined in the literature study. According to expectation theory, people are driven by their conviction that performance, effort, and results are all related. The BSC provides a strategy-based framework for decision-making at various organizational levels. It was created by Kaplan and Norton. The significance of integrating performance assessment in order to increase productivity, quality, customer happiness, and decision-making for small and medium-sized enterprises (SMEs) is underscored by empirical research. Performance in manufacturing is evaluated and optimized via the use of a variety of instruments and methods, including the BSC and KPIs. The study methodology utilized a quantitative analytic strategy with an explanatory approach to comprehend the relationship between manufacturing company performance and supply chain integration. The research philosophy was shaped by positivism, which prioritized quantitative approaches. Semi-structured questionnaires were used to gather data from 213 manufacturing companies; 94% of the respondents answered the questions. The integration of performance measurement has been found to have a favorable influence on the performance of manufacturing organizations through effective communication, information exchange, and strategic supplier relationships. These findings were supported by descriptive statistics. The findings showed a positive relationship between measurement integration and company performance, with integration accounting for 49.9% of the variance in performance. The results showed that efficient decision-making and information exchange among supply chain participants were influenced. Notably, framework agreements with key suppliers were frequently used in emergency situations. The functions of logistics companies, funders, governments, media, and security personnel in relief efforts were emphasized using qualitative analysis.

Logistics Management Practices and Performance of Government-Owned Sugar Companies In Kenya. 肯尼亚政府拥有的糖业公司的物流管理实践与绩效。
Kenneth Kiprono Rutto, Jane Queen Omwenga
In the recent past, the Kenyan government has not been able to ensure the provision of affordable food. Structural bottlenecks have made it difficult for food produced in the country to reach its intended recipients. This study investigated the effect of logistics management practices on performance of government owned sugar companies in Kenya. It was premised on the proposition that in order to increase competitiveness of government-owned sugar companies, it is important to have a sound understanding of their logistics management practices. Underpinned by resource-based view theory, theory of constraints, systems theory and transaction cost theory, this study provided insights into managing logistics to enhance performance within the context of government owned sugar companies in Kenya. Four specific objectives emanated from this main objective: one, to determine the extent to which inventory management affects performance, two, to assess how order management affects performance, three, to establish how transportation management affects performance, four to determine the extent to which packaging management practices affects performance. Out of these objectives, hypotheses were stated for testing. Through structured questionnaires, data was obtained from 5 government-owned sugar companies. Descriptive and inferential statistics were used to analyze the data and test hypotheses of the relationships stated earlier. The target sample population of the study was 256 supply chain personnel from five Government-owned sugar Companies in Kenya. Data analysis was done using SPSS version 29 using both descriptive and inferential analysis. The study finding revealed that inventory, order, transport, and packaging management significantly influence government-owned sugar manufacturing firms' performance in Kenya, explaining 73.9% of performance variation. ANOVA results confirmed the model's statistical significance (p < 0.05). Further analysis demonstrated positive relationships between inventory, order, transport, and packaging management practices and firm performance. The study suggests government and policymakers allocate resources for collaborative research to enhance state-owned sugar manufacturing firms' logistics management. Researchers should focus on cost reduction, quality control, and technology adoption. Sugar firms need to invest in order processing systems, equipment, and sustainable packaging. Logistics service providers should adopt advanced technologies and collaborate with sugar firms. Further studies should explore additional logistics practices and cross-industry collaborations.
近来,肯尼亚政府一直未能确保提供负担得起的粮食。结构性瓶颈使得该国生产的粮食难以送达预定的收货人手中。本研究调查了物流管理实践对肯尼亚政府拥有的制糖公司业绩的影响。研究的前提是,为了提高国有制糖公司的竞争力,必须对其物流管理实践有一个正确的认识。本研究以资源观理论、制约理论、系统理论和交易成本理论为基础,深入探讨了如何在肯尼亚国有制糖公司的背景下管理物流以提高绩效。这一主要目标衍生出四个具体目标:一是确定库存管理对绩效的影响程度,二是评估订单管理对绩效的影响程度,三是确定运输管理对绩效的影响程度,四是确定包装管理实践对绩效的影响程度。根据这些目标,提出了检验假设。通过结构化问卷,从 5 家国有制糖公司获得了数据。研究采用了描述性和推论性统计方法来分析数据,并对前面提出的关系假设进行检验。研究的目标样本人群是来自肯尼亚 5 家国有制糖公司的 256 名供应链人员。数据分析采用 SPSS 29 版本,同时使用了描述性和推论性分析方法。研究结果表明,库存、订单、运输和包装管理对肯尼亚政府拥有的制糖企业的绩效有显著影响,解释了 73.9% 的绩效差异。方差分析结果证实了模型的统计显著性(P < 0.05)。进一步分析表明,库存、订单、运输和包装管理实践与企业绩效之间存在正相关关系。研究建议政府和政策制定者为合作研究分配资源,以加强国有制糖企业的物流管理。研究人员应重点关注降低成本、质量控制和技术采用。制糖企业需要对订单处理系统、设备和可持续包装进行投资。物流服务提供商应采用先进技术,并与制糖企业合作。进一步的研究应探索更多的物流实践和跨行业合作。

Cost Management Practices and Performance of Ministry of Education Funded School Construction Projects in Marigat Sub County 马里加特分县教育部资助学校建设项目的成本管理做法和绩效
Benjamin Maitano Basil, Margaret Waruguru
Cost approaches to management are necessary for a construction project to operate more efficiently. This study looks at the intricate relationships that exist between cost-control strategies and the success of initiatives to develop the county of Marigat's educational infrastructure. This research attempts to determine the critical connections between cost management strategies and construction project results in light of the challenges associated with successfully completing projects within budgetary limits. The Marigat Sub County Ministry of Education Office reports that 23 out of 32 school construction projects—or 71% of the total are either stopped or falling short of expectations. Therefore, the problem addressed in this study is the significant of cost management practices employed in school construction projects and their influence on construction project performance within Marigat Sub County. The study's overall goal was to examine how cost management practices affect the performance of ministry of education-funded school construction projects in Marigat Sub County. Its specific goals are to evaluate the impact of project resource planning, project cost estimation, and project schedule planning on these construction projects, as well as the impact of each on the ministry of education-funded school construction projects in Marigat Sub County. The findings of the study contributed to existing research by giving insight and evidence-based knowledge regarding cost management practices on school construction projects and how this involvement influences the successful completion and performance school projects. The scope of this research was focused on 132 school projects funded by the Ministry of Education in Marigat Sub County, Baringo. The research adopted a descriptive survey design. The 132 educational programmes in Marigat Sub County that are financed by the ministry of education was the target population. The Yamane formula was used to determine the sample size of the respondents given the total population and the desired level of confidence to get 99 school projects, then a random sampling technique was used to select those 99 school projects from the target population. The study used a questionnaire as data collection tool that was administered to project managers who are school principals. Analysis of data was both descriptive and inferential statistics. The mean score of key performance indicators of project resource planning, cost estimation, cost budgeting, and cost control were above 3.5 out of a maximum of 5 respectively indicating that there was involvement of cost management practices in public school construction projects. The regression model predicts that project resource planning, project cost budgeting and project cost control leads to a .154, .208 and .225 increase in project performance respectfully while project cost estimation leads to .116 decrease. In conclusion, the researcher found that cost management practices in
要想提高建筑项目的运作效率,就必须采用成本管理方法。本研究探讨了成本控制策略与马里加特县教育基础设施发展举措的成功之间存在的错综复杂的关系。鉴于在预算范围内成功完成项目所面临的挑战,本研究试图确定成本管理策略与建设项目成果之间的重要联系。马里加特分县教育部办公室报告称,32 个学校建设项目中有 23 个(占总数的 71%)已经停工或未达到预期目标。因此,本研究要解决的问题是马里加特分县学校建设项目中采用的成本管理方法的重要性及其对建设项目绩效的影响。本研究的总体目标是研究成本管理方法如何影响马里加特分县由教育部资助的学校建设项目的绩效。其具体目标是评估项目资源规划、项目成本估算和项目进度规划对这些建设项目的影响,以及各自对马里加特子县由教育部资助的学校建设项目的影响。研究结果为现有研究提供了有关学校建设项目成本管理实践的见解和基于证据的知识,以及这种参与如何影响学校项目的成功完成和绩效。本研究的范围主要集中在巴林戈马里加特分县由教育部资助的 132 个学校项目上。研究采用了描述性调查设计。目标群体是马里加特分县由教育部资助的 132 个教育项目。在考虑到总人口和获得 99 个学校项目所需的置信度的情况下,使用 Yamane 公式确定了受访者的样本量,然后使用随机抽样技术从目标人口中选取了这 99 个学校项目。本研究使用问卷作为数据收集工具,对身为校长的项目经理进行问卷调查。数据分析采用描述性和推论性统计方法。项目资源规划、成本估算、成本预算和成本控制等关键绩效指标的平均得分分别高于 3.5(满分 5 分),表明公立学校建设项目中存在成本管理实践。回归模型预测,项目资源规划、项目成本预算和项目成本控制分别导致项目绩效提高 0.154、0.208 和 0.225,而项目成本估算则导致绩效降低 0.116。总之,研究人员发现,成本管理实践影响着马里加特分县由教育部资助的学校建设项目的绩效。因此,建议公立学校项目的管理者确保在开展学校建设项目时采用适当的成本管理方法。

The 132 educational programmes in Marigat Sub County that are financed by the ministry of education was the target population. The Yamane formula was used to determine the sample size of the respondents given the total population and the desired level of confidence to get 99 school projects, then a random sampling technique was used to select those 99 school projects from the target population. The study used a questionnaire as data collection tool that was administered to project managers who are school principals. Analysis of data was both descriptive and inferential statistics. The mean score of key performance indicators of project resource planning, cost estimation, cost budgeting, and cost control were above 3.5 out of a maximum of 5 respectively indicating that there was involvement of cost management practices in public school construction projects. The regression model predicts that project resource planning, project cost budgeting and project cost control leads to a .154, .208 and .225 increase in project performance respectfully while project cost estimation leads to .116 decrease. In conclusion, the researcher found that cost management practices in","PeriodicalId":438312,"journal":{"name":"International Journal of Social Science and Humanities Research (IJSSHR) ISSN 2959-7056 (o); 2959-7048 (p)","volume":"87 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140236753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Idealized Influence and Employee Performance in Water Works Development Agencies in Kenya 肯尼亚水利工程开发机构中的理想化影响与员工绩效
Jillo Alexi Kasse, W. Guyo, Y. Muchelule, N. Shalle
This study sought to examine the effect of idealized influence on employee performance in water works development agencies (WWDA) in Kenya. It was guided by Transformational Leadership Theory. A descriptive research design and positivist research paradigm was adopted. The population of this study was the 7 Water Works Development Agencies (WWDAs) while the unit of observation was 450 staff in the organizations. Krejcie and Morgan were used to determine the study sample size of 207 respondents. This study employed stratified random sampling in selecting the sample. The study used primary data collected using a semi structured questionnaire. Data analysis was done using Statistical Package for Social Sciences (SPSS) computer software version 26. Qualitative data collected was analyzed using content analysis and presented in prose form. Quantitative data was analyzed using descriptive and inferential statistics. Descriptive statistics included mean, standard deviation, frequencies, and percentages. The study also computed correlation analysis to measure strength and the direction of linear relationship between variables. Multiple regression models were fitted to the data to determine how the predictor/independent variables affect the response/dependent variable. The study further used hierarchical multiple regression models to measure the moderating effect of legal framework. The findings were presented in tables and figures. The study found that idealized influence has a positive and significant relationship with employee performance in WWDA in Kenya. On moderator, the study found that legal framework has positive significant moderating effect on the relationship between idealized influence and the employee performance in WWDA in Kenya. Based on the findings of this study, it is recommended that WWDA should enhance idealized influence among their leaders to improve their performance. This can be achieved by developing a leadership style that exhibits strong ethical and moral values, and by consistently practicing what they preach. Leaders should also be seen as role models, which can inspire their subordinates to emulate their behavior. Additionally, there is a need to establish effective legal frameworks that ensure transparency, fairness, and accountability in the management of public infrastructure projects, particularly those related to water service delivery. Further studies should explore the impact of other factors such as technology, funding, and political will influence employee performance in WWDA in Kenya.

Influence of Firm Centrality on Supply Chain Performance of Agrochemicals Production Firms in Kenya 企业中心性对肯尼亚农用化学品生产企业供应链绩效的影响
David Kiilu Samson, Dennis Gachibu Chege, Nancy Waithira Mwangi
Characteristically, the supply-chain managers attempt to optimize profitable operations in the manufacturing and distribution in the supply chain. Integrated supply chain optimization is the large-scale streamlining of the links in the supply chain in such a way as to ensure the optimal operation of the links and actors in the supply chain. However, integrated supply chain optimization has not been extensively studied for its effect on the performance of distribution companies as opposed to manufacturing companies. Therefore, the purpose of the study was to examine the influence of firm centrality on supply chain performance of agrochemical production firms in Kenya. The Embeddedness theory guided the study which was also grounded on a positivist philosophy. This study employed the descriptive survey design targeting 32 agrochemical production firms with the unit of observation consisting of 96 persons being one management, one procurement and one supply chain staff per firm. The study adopted the census method and used primary data collected using researcher designed questionnaire and interview schedule that were both pretested using the test-retest method for reliability and content and construct validity. Data was analyzed using descriptive and inferential statistics with descriptive statistics comprising frequencies, percentages, means and standard deviations while inferential statistics comprised Pearson’s correlation coefficient and multiple regressions. The findings revealed that Firm Centrality was a strong predictor of Supply Chain Performance of Agrochemicals production firms in Kenya.The study recommended that the agrochemical production firms need to build stronger firm centrality in the supply chain.

Psychometric properties of a Swahili-translated Kessler Psychological Distress Scale (K6) in sample of aging Kenyans. 斯瓦希里语翻译的凯斯勒心理压力量表(K6)在肯尼亚老年人样本中的心理计量特性。
James Muruthi, Lucy Maina, Elijah Mwega, Violet Kagai, Alfred Otieno
Objective: The prevalence of psychological distress, such as depression and anxiety, is increasing among Kenyans. However, there is a lack of understanding about its prevalence rates among aging people, and we lack culturally standardized and concise tools to measure it. Method: This study utilized a sample of 376 older individuals obtained from three regions in Kenya to investigate the distribution, prevalence, and psychometric properties of a Swahili-translated version of the Kessler Psychological Distress Scale (K6). A significant advantage of the K6 is its capacity to measure various mental health factors despite its conciseness. Results: Distribution assessments reveal that most participants reported high psychological distress scores (13 or above), and women experienced significantly higher rates compared to men. The K6 indicators showed high internal consistency for the sample (alpha =.83). Exploratory factor analysis showed the six items loading to on 1 factor and subsequent confirmatory analysis demonstrated excellent fit (CFI = .95; RMSEA = .03) for the one-factor model. Discussion: The high occurrence of psychological distress among the sample highlights this mental health problem as a potentially urgent area of need in the entire Kenyan population. Factor analysis results suggest that the Swahili-translated K6 is a concise tool with great potential for assessing psychological distress among older Kenyans
目的:在肯尼亚人中,抑郁和焦虑等心理困扰的发生率越来越高。然而,我们对其在老年人中的流行率缺乏了解,也缺乏文化标准化的简明工具来测量它。研究方法本研究从肯尼亚的三个地区抽取了 376 名老年人作为样本,调查斯瓦希里语翻译版凯斯勒心理压力量表(K6)的分布、患病率和心理测量特性。K6 量表的一个显著优点是尽管简洁明了,却能测量各种心理健康因素。结果分布评估显示,大多数参与者的心理压力得分较高(13 分或以上),女性的心理压力得分明显高于男性。K6 指标在样本中显示出较高的内部一致性(α=.83)。探索性因素分析表明,六个项目负载于一个因素,随后的确认分析表明,单因素模型具有极佳的拟合度(CFI = .95;RMSEA = .03)。讨论样本中心理困扰的高发生率凸显了这一心理健康问题在整个肯尼亚人口中的潜在迫切需求。因子分析结果表明,斯瓦希里语翻译的 K6 是一种简明的工具,在评估肯尼亚老年人的心理困扰方面具有很大的潜力。

Effect of Risk Identification on Project Implementation among Faith Based Construction Projects in the Diocese Of Ngong 恩贡教区基于信仰的建筑项目风险识别对项目实施的影响
Peter Kennedy Otieno Mutula, Pamela Engairo
Projects are marred with various challenges and uncertainties from the onset of their inception to implementation and completion phases. These uncertainties if not mitigated properly affect subsequent delivery of project objectives thereby causing delays, cost overruns and sometimes may lead to project failures.  Therefore, risk management practices are major features in project management that project managers, project teams and related stakeholders must effectively employ to deal with the risks and uncertainties that may interfere with the projects in order to realize the project success. This study therefore sought to analyze the analyzed the effect of risk identification on project implementation among Catholic Church construction projects in the Diocese of Ngong. Contingency theory informed the foundation upon which the study variables were reviewed to establish their relationships. The study adopted a descriptive case design to analyze how risk management practices affect the implementation of projects in Catholic Diocese of Ngong. The target population involved 240 members that were drawn from the PPC and PEC. The sample size was 72 members whom were selected by simple random sampling and purposive sampling techniques to give each member in the population a chance of selection and ensure that only those with relevant information are involved in the study. A structured questionnaire aided in gathering primary data for the study. The questionnaires were issued to the respondents through a drop and pick method and data collected were analyzed with the help of statistical packages for social sciences (SPSS) version 23. Quantitative data were analyzed using descriptive analysis while qualitative data were analyzed through content analysis and data presented in frequency tables, pie charts and graphs. The results also showed that there was a weak positive significant relationship between risk identification and project implementation though these had a direct link to a successful project implementation. The study recommended that organizations should formulate and put in place elaborate risk identification strategies to enable them succeed in their project implementation. The researcher further recommends for more studies to be conducted on risk management practices other than the ones the study concentrated as they only accounted for 86.8%.
项目从开始到实施和完成阶段都会遇到各种挑战和不确定因素。这些不确定因素如果得不到适当缓解,就会影响项目目标的后续交付,从而造成延误、成本超支,有时甚至可能导致项目失败。 因此,风险管理实践是项目管理的主要特征,项目经理、项目团队和相关利益方必须有效地利用风险管理实践来应对可能干扰项目的风险和不确定性,以实现项目的成功。因此,本研究试图分析恩贡教区天主教堂建设项目的风险识别对项目实施的影响。研究以权变理论为基础,对研究变量进行了审查,以确定它们之间的关系。研究采用描述性案例设计,分析风险管理实践如何影响天主教恩贡教区内项目的实施。目标人群包括从 PPC 和 PEC 中抽取的 240 名成员。样本量为 72 名成员,通过简单随机抽样和目的性抽样技术选出,以使人口中的每个成员都有机会被选中,并确保只有掌握相关信息的成员才能参与研究。结构化问卷有助于收集研究的原始数据。问卷通过投放和抽取的方法发放给受访者,收集到的数据在社会科学统计软件包(SPSS)23 版的帮助下进行分析。定量数据采用描述性分析法进行分析,而定性数据则采用内容分析法进行分析,并以频率表、饼状图和图表的形式展示数据。研究结果还显示,风险识别和项目实施之间存在微弱的正向显著关系,尽管这些关系与项目的成功实施有直接联系。研究建议,各组织应制定并实施周密的风险识别战略,以便成功实施项目。研究人员还建议对风险管理做法进行更多的研究,而不是研究集中的那些做法,因为它们只占 86.8%。

Determinants of Supply Chain Performance in the Energy Sector in Kenya: A Case Study of the Kenya Power. 肯尼亚能源行业供应链绩效的决定因素:肯尼亚电力公司案例研究
Francis Opuka Omollo, Sammy Odari
The current supply chain management in Kenya energy sector is deficient of an acceptable SCM performance level due to the inability to connect every willing buyer, and the cost of rural electrification by grid development due to dispersion as is expected in the service charter. The general objective of the study was to establish the determinants of supply chain performance in the energy sector in Kenya with an inclination to KPLC. The specific objectives of the study were to; determine the effect of information communication technology on supply chain performance of KPLC; examine the effect of buyer-supplier relationship on supply chain performance of KPLC; determine the effect of procurement professionalism on supply chain performance of KPLC and establish the effect of contract management on performance of KPLC. The study employed a descriptive research design. The researcher used stratified random sampling technique. The study population was 698 employees working in KPLC from which 254 respondents were selected. Questionnaires were used as the main data collection instrument and a pilot study was undertaken to pretest the questionnaires for validity and reliability. For the purpose of analyzing the data that was gathered, and the Statistical Package for Social Sciences Version 24 was utilized in analysis. In order to establish the statistical link between the independent factors and the predicted variable, the study made utilization of the regression model. Descriptive statistics were computed whereby frequencies, percentages and means were clearly shown in the form of both tables and figures. The study revealed that a unit increase in the elements of information communication technology, procurement professionalism, buyer-supplier relationship and contract management will translate to improvement of supply chain performance in KPLC. the study recommends that KPLC and other firms in the energy sector should exploit the aforementioned determinants in a hierarchical order. This would enable KPLC and other firms in the energy sector to focus on the determinants with the most positive significant effect on supply chain performance and prioritize resources allocation and deployment appropriately. The study recommends this order, buyer-supplier relationships, followed by contract management while information communication technology and procurement professionalism should be exploited concurrently.
肯尼亚能源部门目前的供应链管理缺乏可接受的供应链管理绩效水平,原因是无法连接每一个愿意购买的买家,而且由于服务章程中预期的分散性,电网发展导致农村电气化成本高昂。本研究的总体目标是确定肯尼亚能源行业供应链绩效的决定因素,重点关注 KPLC。研究的具体目标是:确定信息通信技术对 KPLC 供应链绩效的影响;检查买方-供应商关系对 KPLC 供应链绩效的影响;确定采购专业性对 KPLC 供应链绩效的影响;以及确定合同管理对 KPLC 绩效的影响。本研究采用了描述性研究设计。研究人员使用了分层随机抽样技术。研究对象为在 KPLC 工作的 698 名员工,从中抽取了 254 名受访者。研究人员使用问卷作为主要的数据收集工具,并进行了试点研究,以预先测试问卷的有效性和可靠性。为了对收集到的数据进行分析,使用了社会科学统计软件包第 24 版。为了建立独立因素与预测变量之间的统计联系,研究使用了回归模型。研究计算了描述性统计,以表格和数字的形式清楚地显示了频率、百分比和平均值。研究结果表明,信息通信技术、采购专业性、买方-供应商关系和合同管理等要素每增加一个单位,KPLC 的供应链绩效就会提高一个单位。这将使 KPLC 和能源行业的其他公司能够关注对供应链绩效具有最积极重大影响的决定因素,并适当优先分配和部署资源。研究建议按以下顺序排列:买方-供应商关系,其次是合同管理,同时应利用信息通信技术和采购专业化。
