Technical Sessions – Monday July 11

Two models characterize knowledge creation in a NPD project with three parallel
stages: prototyping, pilot line testing, and on-line experimentation. We
determine the optimal rates each activity should be pursued over time. We recognize
knowledge gleaned from prototyping (pilot line) transfers and benefits
pilot line (on-line) activities. In one model, knowledge transfer is fluid and occurs
continuously over time reflecting highly interactive teams. In the second
model, knowledge is accumulated at one stage and transferred to the next stage
at discrete times reflecting teams that work separately. The manager maximizes
revenue earned when the product is released less development costs.

Collaboration in a team contributes to an improved performance in two aspects,
superior work efficiency and the attainment of higher goals. The former
expects an effective method to achieve a goal and the latter a work of higher
quality. We examined the success of a team collaboration by utilizing an indicator
originally developed to measure personal performances, defined as the
excess beyond the predetermined goal. This indicator advantageously allows
for the combining of various evaluation factors and also has the capability to
directly compare performances from different teams.
3 - Minimising the Gap: Developing Organisational Approaches
to Support Personal Knowledge Management
through Technology

Organisational strategies to support personal knowledge management through
technological approaches should reflect individual learner needs. Insight into
these individual attributes informs efficient delivery approaches to build on existing
practice and maximise participant understanding. Various styles of audience
engagement enables individuals to feel "ownership’ of their developing
knowledge and confidence in its use. A case study from a corporate organisation
illustrates an organisational delivery model to maximise the quality of the
learning experience.

1 - Improving Container Terminal Efficiency by Utilizing
Twin Load Capability of Straddle Carriers

At a seaport container terminal where the quay-side transport and the stacking
operation are performed by self lifting vehicles, a major challenge is to
achieve fast vessel turn-around times by dispatching these vehicles efficiently.
Only limited attention has yet been given to the vehicle’s twin-load capability.
Despite particular balancing problems in certain circumstances, this capability
can improve efficiency dramatically when utilized correctly. We propose a dispatching
strategy for twin load straddle carriers and test its performance in an
exhaustive discrete event simulation study.
2 - Increased Environmental Concern Adds Another Dimension

Shipping companies must manage their fleets effectively in order to stay in
business. Ship scheduling and routing which concerns the optimal assignment
of available cargoes play an important role in this respect. Increased environmental
concern due to climate change adds another dimension to the scheduling
and makes it multi-objective. This study focus on enabling vessel and fleet operation
in the most environmental friendly way as a function of sea states for
given voyage requirement such as minimizing voyage fuel consumption, minimize
voyage cost, maximize revenue or maximize profit.
3 - Optimization of Machinery System in Conceptual Ship
Design

Decisions on machinery system are made during conceptual phase of ship design.
This paper presents a decision tree model for deterministic optimization
of machinery systems. Machinery selection deals with determining type and
number of engines, their capacities and internal connections for satisfying demand
for propulsive, maneuvering and electrical power. The proposed model
considers energy efficiency and emission to air over the vessel’s lifetime on the
assumption that the vessel’s operations are known. A computational study is
carried out and suggestions are made for further work.
4 - Ongoing Reform in Australian Ports: The Move towards
Chain Integration
Sophia Everett, Australian Maritime College, University of
Tasmania, TAS 7001, Hobart, Australia, sophiae@amc.edu.au
The objective of port reform in Australia has been underway since the 1980s.
Driven by a market oriented policy agenda reform initially focused on efficiency
improvements and the reduction and/or elimination of ongoing deficits.
In more recent times the focus has included the notion of integrating the ports
into efficient supply chains. This paper will examine recent policy and legislation
changes in a number of Australian state government jurisdictions in a move
towards chain integration. It will evaluate the rationale behind these changes
in a number of Australian states and the success or otherwise of government
policies.
