Motion of cranes of bridge type simulation in the MS Excel environment

The idle times of the crane caused by need of replacement of wheels, can have critical value for functioning of a logistic chain. In article the task about the movement of the crane with a skew with the accounting of several mutually influencing processes having various nature is considered. The solution of this task has important applied value for increase in a resource of wheels. For the crane designs, more varied, a known problem is representation of results in a suitable form for engineering calculations, as a compromise between simplicity and quality of the results. Possible solution is modelling in the environment of MS Excel. This approach allows the best way to provide the necessary engineering calculations for simplicity, clarity and reliability of the submission and processing of a large number of heterogeneous data. As an example, modelling of an elastic skeleton of the crane in dynamics that represents complexity in view of lack of specialized mathematical apparatus is considered

Modelling and simulation framework for reactive transport of organic contaminants in bed-sediments using a pure java object - oriented paradigm

Numerical modelling and simulation of organic contaminant reactive transport in the environment is being increasingly relied upon for a wide range of tasks associated with risk-based decision-making, such as prediction of contaminant profiles, optimisation of remediation methods, and monitoring of changes resulting from an implemented remediation scheme. The lack of integration of multiple mechanistic models to a single modelling framework, however, has prevented the field of reactive transport modelling in bed-sediments from developing a cohesive understanding of contaminant fate and behaviour in the aquatic sediment environment. This paper will investigate the problems involved in the model integration process, discuss modelling and software development approaches, and present preliminary results from use of CORETRANS, a predictive modelling framework that simulates 1-dimensional organic contaminant reaction and transport in bed-sediments

Domain modelling and the co-design of business rules in the telecommunication business area.

This paper discusses the development of an enterprise domain model in an environment where part of the domain knowledge is vague and not yet formalised in company-wide business rules. The domain model was developed for a young company starting in the telecommunications sector. The company relied on a number of stand-alone business support systems and sought for a manner to integrate them. There was opted for the development of an enterprise-wide domain model that had to serve as an integration layer to coordinate the stand-alone applications. A specific feature of the company was that it could build up its information infrastructure form scratch, so that many aspects of its business were still in the process of being defined. The paper will highlight parts of the Enterprise Model where there was a need for co-designing business rules together with the domain model. A result of this whole effort was that the company got more insight into important domain knowledge and developed a common understanding across functional areas of the way of doing business.domain modelling; business rules; object-oriented analysis; business process modelling;
