ASSESSMENT OF COST OPTIMIZATION FOR PORT OPERATIONS
ABSTRACT
It is very fundamental that man's main aim of venturing into businesses of all kinds is to make profit. Though profit tends to grow with time, a better planning, analysis and implementation strategy can in a least expected manner bring efficiency, stability and the much needed profit. The maritime sector of the Nigerian economy is one that has a lot of resources that are been utilized in the course of its day to day operations. The resources engaged in this sector ranges from human, to finance and technological know-how. This research study is therefore determined to optimize the cost of port operations in Nigeria with a view to critically analyze it from the perspective of linear programming model. The quantitative estimates used here were concerned with the activities associated with the operations of Nigerian ports, the costs and the benefits derived by users of these ports etc. A Linear Programming Model as earlier indicated was formulated from the cost components associated with the vessel-port relationships. With the aid of M for Windows Software, an optimal solution was derived. Then the result showed indicated the minimum cost of port operations as well as the optimal time frames for the decision variables of port operations under review. This provides a basis for future projections so as to determine the range of values of the constraints and decision variables for which the Nigeria port operations could be at minimal cost.
CHAPTER ONE
1.0 Introduction
1.1 Background of Study
The globalization of trade and subsequent breakdown in trade barriers has generated tremendous growth in maritime transportation. Thus the stiff competitions among part operators have increased the desire to attract port uses. Therefore, port operators will have to optimize the cost of their operations if they must benchmark good productivity and performance for their terminals. There is no doubt that the maritime sector especially the port system is vital and instrumental to the national economic survival of the country. Nigeria is a popular nation, renowned for her international nature of business. Quality customer service is the benchmark principle for the maritime professional and customer care techniques. Therefore, the economic justification of a port is its ability to satisfy its customers at a lower price and also be able to make profits.
The lowest investment cost (the lowest price) is often the only priority in the process of preparation of the budget in a construction project. If we consider a building's lifespan as tens of years, assessing project alternatives in terms of only investment costs occurs as shortsighted and insufficient. Running costs (operation costs, maintenance and renovation costs) are an important section of investment during the life cycle. Life cycle costing (LCC) should be an inseparable part of decision making on financially expensive investments, which most construction projects can be classified. Calculation of life cycle costs provides a completely new economic view on building design. This paper covers the implementation and incorporation of the LCC criterion in decision making cycle for preparation of construction projects. RICS (Royal Institution of Chartered Surveyors) introduced a method of collecting data about running costs of buildings in 1971 (BMCIS - Building Maintenance Cost Information Service). The British ministry of industry published a document “Life-cycle costs in the management of assets” in 1977.
It is evident that Nigerian ports operate at very low optimal capacity, in spite of the expected large volume of cargo traffic that passes through it. It is very pertinent to note that vessel delay period is a very serious problem that contributes to over 60% of our ports low productivity problem in recent times. Ndikom (2008), further confirms that regrettably, at Lome port, dock workers load 700mts per day as against less than 250mt per day at Nigerian ports. The five days difference in loading arrangements between Nigerian ports and other ports in terms of ship delay rate billings of US$4,000 is rather too staggering and unfortunate. In clear terms, this is enough to deny Nigerian ports cargo and revenue that would ordinarily have come our way.
With regards to costs emanating from the vessel, it can be affirmed that port costs, above all are the most significant, since they depend on the gross tonnage of the vessel and the time it spends in the port. Bulk carriers are those which tend to spend most time in port as well as being the greatest in size. The costs of towing, which depend on the circumstances of the movement, tend to represent approximately 10% to 15% of the cost scale of the vessel (Valverde, 1995). More so, other costs due to the vessels stay at port, including agency fees average approximately 5 or 10% of the total. The port tariffs on the merchandise are situated at less than 50% of the total. Where all costs of unloading are considered in relation to port costs, the former are situated at about 70% of the total where all costs are also included storage, weighing etc. With a clear tendency to drop when using cranes of greater efficiency and capacity, about 30% would correspond to port costs.
According to Kaspi et al. (2006), He looked at the minimization of cost and optimum port performance as anchored on reducing port turnaround time. They developed a regression model to relate turnaround time and port cost which was highly related with allocation of port facilities. Beatriz et al (2004), argues that the optimal organization of the industry can be studied by means of cost and production functions. They reviewed the literature on econometric ports' structure and propose that the calculation of key cost indicators (economics of scale, scope and so forth) is best in determining optimal port structure is order to minimize the cost of port operations.
In many markets, firms compete over time by expending resources with the purpose of reducing their costs. Sometimes, the cost reducing investments operate directly on costs. In many instances, they take the form of developing new products that deliver what customers need more cheaply. Therefore, product development can have the same ultimate effect as direct cost reduction. In fact if one thinks of the product as the services render to customers, then product development often is just cost reduction.
