The Model of Support for the Decision-Making Process, While Organizing Dredging Works in the Ports

Abstract

The aim of the research was to create a decision-making model, which would be able to support planning, organizing and conducting the dredging works in the port area. The proposed solution is a multiple element system which enables to verify, in a comprehensive way, the majority of the aspects determining the quality and the time of dredging enterprise realization. The paper presents an original approach to the decision-making process during the organization of dredging works, using the computer program. In order to achieve the main goal of the study, the conditions of dredging works were considered. Furthermore, the factors that have an influence on the schedule of the project were evaluated and algorithms, as well as process organization schemes, were developed. If it is not enough, the decision models corresponding to the discussed issue were analysed and the computer program was created. And last but not the least, the proposed project and equipment were verified using a simulation model. While creating this model, the method of multiple criteria AHP (Analytic Hierarchy Process) decision support was used. Moreover, the mass service model with the priority queue regulations, the expert study, and statistical analysis of the traffic flow, were provided. The model was developed in reliance to multiple criteria studies, based on the opinions of multinational experts. These enabled to adjust each element of the system in accordance with various locations. As a result of the research, the following thesis has been proven, that detailed analysis of the conditions of dredging works and taking into account the received conclusions enables to reduce the costs and shorten the time of dredging projects realizations.

Risk Analysis of Seaport Construction Project Execution

“…One classification distinguishes between internal and external threats. External threats include all factors outside a technical facility that affect its safety, originating from: nature, products of human civilization or other people [23][24][25], traffic intensity, navigational conditions in a given area, etc. Although these are threats traditionally inscribed in the history of human experience, there is still a lack of sufficiently effective means to limit their negative effects [26].…”

Assessment of Dredging cost through Comparative Analysis A case study of Dredging System in Lagos Metropolis

“…The most important factor affecting the efficiency of the excavation process is the equipment capacity of the dredgers. While dredging project construction brings economic benefits to the country, it also brings huge challenges and high uncertainty (Cheng et al, 2022;Kaizer, A., and Neumann, 2021). In the design and implementation of any dredging project, each part of the dredging process must be closely coordinated to ensure a successful dredging operation.…”
