Candian port administraion: its future structre

The administration, management and development of ports in Canada is a Federal government responsibility. This centralist control of ports has been the subject of criticism by many for a variety of reasons, not the least of which is that it is not responsive enough to the affairs of the local level. This problem, along with others, has resulted in the introduction in the Canadian Parliament of proposed legislation over the past five years to alter port administration and development in Canada. The proposals culminated in the recent passage of the Canada Ports Corporation Act which, among other things, will see the abolition of the National Harbours Board. A review of the administrative structure the new Act replaces, along with a review and assessment of the Act itself and the proposed legislation which predated it, forms the basis of this paper. It will be seen that because of the new Act the centralist approach to port administration is maintained, but greater local autonomy and financial self-sufficiency will also be available to ports. However, the central administration will still have the problem of co-ordinating the development of Canadian ports, since ports will continue to be constituted under at least four different pieces of legislation.     

TRAMS: Transit route animation and modelling by simulation

Public transport managers and operators face increasingly difficult problems in providing adequate levels of service at reasonable social and financial costs. A greater demand exists for analytical techniques which allow them to evaluate changes in operational strategies before committing themselves to implementation in the field. This paper describes the development of a discrete event simulation model for the analysis of on-street transit routes. The structure of the model is described and details are provided of the types of events which are explicitly modelled in the TRAMS package. The input requirements are described, and the modular nature of the simulation model is highlighted. The various options for output format are described, including the use of a computer graphics real-time animation option. The range of output performance measures are then discussed, and some comments on areas of application conclude the paper.     

Aircraft Ground Dynamics

The state-of-the-art in analysing a number of ground manoeuvring processes on aircraft is described. The mathematical models are as good as the data supplied to them.     

Emerging organizational values in shipping: Part 4. Decentralization—the redefinition of authority in shipping company organization

Decentralization is a major theme of organizational change in shipping. It is often seen as 'putting power back aboard ship'. However, the authors argue that this view is too simple. Decentralization poses fundamental questions about the entire management structure of the shipping company. The redistribution of authority necessary for decentralization is discussed in terms of the company organization structure.     

The simulation of a fork-lift truck and crane transfer operation

The authors of this paper make use of computer simulation techniques as a means of investigating the problems associated with minimizing a ship's turn-round time.
