“…Simulation tools are capable of analyzing the shop floor under different scenarios by just changing values and performance measures. Another research [2] used discrete simulation model of transport system to improve variation number and size of vessels in order to get efficient and effective pattern. Simulation is used [3] for shop floor control system that controls current status and information provided by controller.…”

In recent times, the globalization of markets due to the improvement of utilization of resources has significant impact on the manufacturing systems. International competition forced companies to establish efficient and effective production facilities that provide best possible outcome in terms of profitability, throughput and lead time. In this background, every industrial facility is in competition to remain competitive in the market and be flexible for future changes. It is not easy to change the environment of any facility in order to check the results beforehand therefore simulation is a viable option. Simulation tools are used to help analyze performance measures for improvement. This paper presents a case by analyzing a facility in order to improve its production using simulation tool. In this study, simulation model for the production facility of Fort Ceramic Company is developed from its current state and then changes are made to its inter-arrival time. Models for both improved and current systems are developed in the simulation tool. Data analyzed in the simulation tool shows better results that represent a significant improvement in productivity, cycle time and throughput time to optimize the system.It is also observed that by decreasing the inter arrival time there is increase in the throughput which improves the revenue.

Abstract-one of the facilities and infrastructure of the vessel is the ventilation system in the cargo hold to maintain the quality. One attempt to avoid high moisture ratios is to provide a dry air supply by using desiccants. The purpose of this thesis is to design the system of air ventilation with solar desiccant by analysis the calculation with decrease air humidity ratio after passing desiccant rotor as well as fulfillment needs of heater and cooling system using heat of exhaust gas and seawater as well as fulfillment of electricity need using solar energy. From the result of analysis obtain to provide air supply in the cargo hold of 437.5 m 3 / hour, the specification of rotor desiccant has a diameter of 550 mm with thickness 200 mm to decrease ratio of outside air humidity equal to 83.1% become 46.5%. Dehumidification air temperature of 47.7 o C will be lowered to 35 o C by using the sea water cooling media. As for the reactivation air heater requirement of 24.292 kW would be to fulfilled by utilizing the exhaust power of 498.12 kW. And for the electric power needs of the syetm is 34,488 wp will be supplied from the total solar module is 33 units with 345 wp per-capacity.

Abstract every ship project would not be apart from risk and uncertainty issues. The inappropriate risk assessment process would have long-term impact, such as financial loss. Thus, risk and uncertainties analysis would be a very important process in financial feasibility determination of the project. This study analyzes the financial feasibility of 17,500 LTDW tanker project. Risk and uncertainty are two differentiated terminologies in this study, where risk focuses on operational risk due to shipbuilding process nonconformity to shipowner finance, while uncertainty focuses on variable costs that affect project cash flows. There are three funding scenarios in this study, where the percentage of funding with own capital and bank loan in scenario 1 is 100% : 0%, scenario 2 is 75% : 25%, and scenario 3 is 50% : 50%. Monte Carlo simulation method was applied to simulate the acceptance criteria, such as net present value (NPV), internal rate of return (IRR), payback period (PP), and profitability index (PI). The results of simulation show that 17,500 LTDW tanker project funding by scenario 1, 2 and 3 are feasible to run, where probability of each acceptance criteria was greater than 50%. Charter rate being the most sensitive uncertainty over project's financial feasibility parameters.
