Abstract: A lot of problems that emanate from complexity could have been mitigated or even avoided, if the factors that render a project complex and the risks that they induce, were fully comprehensible in order for a more appropriate management process to be established. The aim of this study is the comprehension of the meaning of complexity in engineering projects through the identification of the factors that affects it based on which a project complexity measurement model is proposed. To that end an extensive literature review has been conducted in order to detect as many factors already identified by previous researchers as possible and to categorize them in a way that can integrate the existing theoretical and empirical approaches. Through that study, 21 factors that contribute to the complexity of engineering projects were distinguished. Afterwards, following the results of a questionnaire survey that was carried out and upon implementing factor analysis on its data, 7 key factors were discerned as the main components of the complexity variables. Finally, using a simplified method of multiple-criteria decision analysis, namely Single Multi Attribute Rating Technique Exploiting Ranking – SMARTER, a practical and approachable model of complexity measurement has been introduced, named Complexity Level Indicator – CLI.

Abstract: Insufficient and irregular power supply in Ghana has been a matter of concern to all. This situation runs through all industrial, commercial and domestic sectors of the Ghanaian economy, posing much challenge to the economic growth. This study considers the Beauty Salon industry which is one important but neglected industry which depends mostly on power for all its activities, and also consumes a lot of energy. In the beauty salon industry, about 73% of the work force is women which falls under the hairdressing with the remaining being barbers. The research shows that, about 96% of their business operations depend on the National Electric grid. Finding an alternative means to provide electrical power source is of much significance. Notwithstanding this, the total average income of GH₵8,443, expenditure of GH₵3,488 and GH₵1,951 being the expenditure of light provision in the absence of national grid. Aside this, the cost of electricity bills keeps raising making the industry being under critical condition to stay in business. Therefore the study identifies various tools and equipment used in the industry and their power ratings to propose a possible design of photovoltaic (PV) system for the industry. This study proposes a 2.8KW Stand-alone Photovoltaic System to help solve the problem of entrepreneurs in the Beauty Salon industry. In view of this study, it can be recommended that, this PV can be implemented to promote it use in the Beauty Salon industry by the Ghana government and other donor agencies to sustain the burden on the industry. Also the study identifies the need for education of power management as most entrepreneurs in the Beauty industry have little knowledge on it.

Abstract: This paper presents the detailed analysis of recruitment and selection of a leading telecom company. The process of selection consists of three stages which are recruitment, screening and selection. The research methodology uses data collection, sampling, and data analysis. The initial research has been done using Observation, Questionnaire, and Personal interaction. Further, newspapers clippings (Regular Articles on Current HR Trends in HT Power Jobs area of Hindustan Times) have also been used to conclude the results.

Abstract: This report review international literature on linear programming and how it applies to investment appraisal. It highlights the acceptable methods on investment appraisal and describes the major aspect of investment appraisal. The research review literatures and identify the distinctions between the research as well as providing explanations for them. The discounted and non-discounted techniques of investment appraisal were examined and the study further studied the relationship between linear programming and how it applies to investment appraisal. Thus this study identifies the relationship between linear programming and investment appraisal.

Abstract: Several research efforts have been made to establish the acceptability of contractors’ prequalification criteria as basis for choosing a contractor to handle the delivery of projects with emphasis placed on the reliability of contractors’ prequalification criteria to yield expected result. No matter the choice of the criteria adopted in selecting the contractor, its appropriateness becomes manifest during execution. Therefore, the essential ingredients needed to meet the demands of smooth administration of civil engineering project is portrayed in the various attributes associated with the criteria adopted during contractors’ prequalification exercise. Hence, this study purposely delves into these attributes as a way of exploring the potentials of contractors’ prequalification criteria geared towards enhancing their reliability to ensuring hitch-free administration of civil engineering project. Its scope comprises clients, contractors and consultants engaging in civil engineering projects. This study shows that contractors’ prequalification criterion for civil engineering project is five-dimensional while its potential attributes are essential tools depicting the diverse civil engineering project administration areas where contractors’ competence is mostly needed.
