Karim, Osman
This thesis is a comparative analysis between meantime between failure (MTBF) and
maintenance free operating period (MFOP) of mills Asset Management at Anglogold
Ashanti Iduapriem Limited. Management often consider such factors considered in their
budgetary allocation. The work developed a methodology using the data on the Mills to
determine the health status of the Mills and to conduct a comparative analysis between
Maintenance Free Operating Period (MFOP) which is not popularly known in the Mining
Industries with the popularly known and frequently used reliability metric Mean Time
Between Failure (MTBF). The results indicates that the MTBF stoppage intervals were
0.1 to 0.3 weeks whiles that of MFOP ranges from 0.2 to 7.1 weeks. This indicates that
the MFOP gives mining firms higher reliability of equipment as compare to MTBF. The
result was affirmed by a mine site engineer who said “the existing maintenance metrics
(MTBF) has not been able to help Iduapriem mine to holistically deal with its maintenance
and breakdown challenges.” This work exposes the inherent errors in MTBF applications
and the benefits of applying MFOP, these errors have two significant implication from
regulators perspective and competitive edge of the organisation.

Aninakwa, Evelyn
The extractive industry has evolved over a few decades with major emphasis on its core
activities with the sole purpose of maximising profit. The major concern has been focusing
on their key departments, such as mining and maintenance. Until recently, little emphasis
was placed on the other service areas as they were not directly involved in the core activities
within the industry. However, a major shift to focus on other service delivery areas
confirmed that the extractive industry can greatly reduce costs and maximize profit if
efficiently managed. Among the service areas which were given prominence is the supply
chain function. Supply Chain Management is one of the key components responsible for
balancing demand and supply along the entire value-adding chain, including contract
management. Workers’ skills are the most important asset that contributes to market growth.
Many companies have established their contracting forces without investing in qualified and
competent contract management. This study seeks to assess the technical competencies of
indirect employees involved in the contract management cycle and its impact on contract
management at Abosso Goldfield Limited. The primary objective of the research was geared
towards assessing the existing indirect employee’s technical competencies and their impact
on the contract management cycle, as well as strategies to improve deviations in the contract
management cycle. The primary data collected was analysed using Excel and SPSS for
statistical and inferential analyses respectively. The research established that indirect
employee technical competencies significantly impact contract management. Therefore, it
is paramount that cogent reforms such as effective recruitment processes and specific
training such as on the job training are implemented to enhance their competencies.

Otchere, Prince Kofi
The movement of goods and services severely impacts the development of the supply chain and
urban sustainability. Both scholars and decision-makers have recently given the idea of city
logistics and intermodality a lot of attention. City logistics are crucial to maintaining the
viability of metropolitan regions in which urban freight transportation also significantly
impacts how well people live there. Optimizing urban freight transportation substantially
impacts the sustainability and livability of cities and urban areas by lowering traffic
congestion, minimizing traffic accidents, and attenuating the effects of CO2 emissions and
noise. The supply chain of mining and sub-contractor companies in Tarkwa is mostly done by
road freight which creates massive environmental, safety and traffic congestion. Therefore,
this thesis evaluates creating a new transport network to haul mining goods and services to a
consolidated logistics platform. To achieve this, a wide range of literature assessments
relevant to peripheral logistics platforms' impact on cities' sustainability were examined. It
appears that there aren't any well-defined models that can provide a thorough and quantitative
evaluation of sustainability for the rerouting of transport networks. Field traffic flow
observation and a case study on Goldfields Damang were used to perform additional research.
A mixed-methods study using both a qualitative and quantitative component was conducted
based on all the data gathered from the pertinent sources. This thesis created a methodical
technique using google Maps and Jupyter notebook to evaluate the significant elements that
affect a move in the context of all three sustainable aspects: social, economic, and
environmental growth. These effects include traffic congestion, travel time and distance,
increased emissions, cost-effective transportation, and improved mobility. The simulation
revealed the necessity of having a new transport link to the consolidated platform to enhance
intermodality. Research must be done into how government and other stakeholders can
partner to build an intermodal logistic platforms with well-enhanced transport networks, and
the use of GIS in location selection to create smart city concepts

Larbi, Stephen Amon
Finance is concerned with how savings from investors are distributed to businesses via
financial markets and middlemen, who then utilize them to fund their activities. After the
inclusion of asset pricing’s uncertainty, it was discovered that older analysis could not
explain many aspects of corporate finance.
Game theory is that part of applied mathematics that is concerned with how agents
communicate with each other through their choices. It has developed a framework that has
contributed to extra knowledge into many unknown phenomena, giving chance for the
inclusion of asymmetric knowledge and strategic engagement.
In this study, a computational study and application of Game Theory Model to investment
decisions in an optimal portfolio selection problem are considered. Emphasis was placed on
an investment decision problem using data from Invest, Grow, Secure (IGS) Financial
Services for the year 2018.
The decision-maker had to select at least one option from all possible options provided by
IGS Financial Services in which an investment was made. The problem was to decide what
action or a combination of actions to take among the various possible options with the given
rates of return.
The study was successful in modeling investment options of investors as a Game Theoretic
Mathematical Problem that maximizes the returns from their investments. The application
of Game Theory in the financial investment strategy is also successful in offering an optimal
solution as opposed to an investor's personal discretionary means. Hence, the investor is
able to make better investment policies decisions based on which combinations of payoff is
providing the optimal value of returns.
Furthermore, the results from the maximization of returns showed that, allocating 20 percent
and 50 percent of the investor’s funds in the first quarter and second quarter respectively,
yielded the maximum returns to the investor. The results from the minimization of cost
however, showed that, allocating 70% of the investor’s funds in a 12 months investment
policy, minimizes the most cost to the company.
