Container terminals world wide are trying to expand capacity and increase performance at a minimum of investments. Often the container terminal operations are changing to meet increased customer demands as well as to adapt to new technologies. The increasing costs of container terminal development do justify the use of computer simulation to assist in planning and policy making. A flexible simu...

Due to rapid growth in foreign trade using sea vessels, there is a growing focus in improving the infrastructure and operational efficiencies at the container terminals. Particularly, the operational responsiveness of loading and unloading of containers, affects the vessel idle times and profitability of the shipping liners. In this research, we determine optimal stack layout design, which mini...

A k-container C(u, v) of a graph G is a set of kdisjoint paths joining u to v. A k-container C(u, v) of G is k∗-container if C(u, v) spans G. A graph G is k∗-connected if there exists a k∗-container between any two distinct vertices. Let κ(G) be the connectivity of G. In this paper, we prove that the n-dimensional burnt pancake graph Bn is n∗connected for any positive integer n.

A k-container C(u, v) of G between u and v is a set of k internally disjoint paths between u and v. A k-container C(u, v) of G is a k∗-container if it contains all vertices of G. A graph G is k∗connected if there exists a k∗-container between any two distinct vertices. In this paper, we prove that the n-dimensional fully connected cubic network FCCNn is 3 ∗-connected for n ≥ 2.

The performance system at the container terminal Semarang Container Terminal (SCT) is not yet good, it can be seen from average dwelling time which still long. Dwelling optimization needs to done in order get a balance of projected increases during trading and compensate for various limitations facilities infrastructure. One them handling procedure using an application, namely cost operating ap...

A pilot scale wastewater treatment plant was designed, constructed and operated on site to treat wastewater from a combined effluent drain. The activated sludge process (ASP) was used at three different hydraulic retention times (HRT) of 12, 10 and 8 hrs at an average MLSS concentration of 3500 mg/L. Under each HRT, the pilot plant was operated for a period of 10-12 weeks. Chemical oxygen deman...

The efforts of modern civilization to create an environment to meet human aspirations have successfully resulted in constant improvements of our lifestyle, but it has increased risks to human and ecological health. This situation has motivated many scientists throughout the world to analyze the environmental factors that can affect our health or ecology and to calculate the levels of risk. In B...

Without significant intervention, demand for crude oil could rise by a further 25% by 2035, stemming from its use for transportation, particularly road transport. Many technologies for alternative fuels and substitute transport energy carriers are being researched, but successful implementation of these technologies at scale will require attention to consumer-behavioural and policy challenges a...

We present three diierent methods for nding solutions to the 2D translation-only containment problem: nd translations for k polygons that place them inside a given polygonal container without overlap. Both the container and the polygons to be placed in it may be nonconvex. First, we provide several exact algorithms that improve results for k = 2 or k = 3. In particular, we give an algorithm for...

We propose a new index, the Container Port Connectivity Index (CPCI), to measure the trade connectivity of ports within the network of container shipping. This index is based on both economics and network topology, and a distinctive feature is that the strength of a port is based on its position within the global structure of the shipping network and not just on local information such as the nu...
