Abstract

Indonesia is a big country having big population, huge area and huge Exclusive Economic Zone area. For world harmonized growth, it is quite important to realize steady economy growth on Indonesia. Growth of Indonesia’s shipbuilding industry specifically is an important part to achieve Indonesia’s maritime vision, but by far as for the shipbuilding market, 3 major countries, China, South Korea and Japan have obtained almost 100% share, which means it is quite difficult to increase the world share. In the volatile marine world, fluctuating oil price often affect production capacity, and investment decision is hard to get with TOP management. Indonesia shipbuilding industry has big mission under severe management and environmental condition. We clarify basic dilemma / conflict inhibiting the growth of Indonesia shipbuilding industry under assumption of severe management environmental condition, with Theory of Constraints (TOC). The basic dilemmas are solved by erasing the reason of existence of opposite activity and the Indonesia shipbuilding ever-lasting development logic is proposed with the solution of basic dilemma.

Abstract

With growing ship size and demand for effective handling of container cargoes in recent years, automation has inevitably took place in almost all aspect of modern terminal operation. So far, automation has been led by the large terminals in Europe and North America and soon it will become a pressure for terminals in developing countries to go for automation. The drawbacks heavily rely on the initial investment cost and question arises with regard to effectiveness of automation for medium and small size container terminals. A visual environment that simulates container terminal operation is developed to facilitate investigation advantage and disadvantages of automated container terminal compared to conventional container terminal. A discrete event model for container handling process and agent-based model for path mover flow system is built and validated based on operating terminal in real world and visually simulated to serve the objective. The result of the computer simulation is an evaluation of performance metric for both terminal concepts under similar arrangements. In addition, visual simulation was able to notify the area where advantage and disadvantage of both concepts will take place during operation.
