Alias analysis is a method for extracting sets of expressions which may possibly refer to the same memory locations during program execution. Although many researchers have already proposed analysis methods for the purpose of program optimization, difficulties still remain in applying such methods to practical software engineering tools in the sense of precision, extensibility and scalability. ...

Although the field of program comprehension as a research discipline has evolved considerably over the past years, only little is known about how software engineers perform their work. In this paper, we report on an observational study that we have carried out to investigate how software developers understand code when they approach a given maintenance task. We particularly focused on the devel...

In maintenance services skills management is directly linked to the performance of the service. A good human resource management will have an effect on the performance of the plant. Each task which has to be performed is characterized by the level of competence required. For each skill, human resources have different levels. The issue of making a decision about assignment and scheduling leads t...

Today, maintenance strategies and their analyses remain a worrying problem for companies. Our study, presented in this paper, shows that our indicator can provide help for expert decision (maintenance manager) in the context of condition-based maintenance. The paper deals with the proposition of using Hidden Markov Models to track and estimate the degradation of a system, according to observati...

In many developing countries, roads and highways are the dominant mode of transport. Road-based transport typically accounts for more than 80% of the distance travelled by individuals and more than 50% of that travelled by goods. Consequently, a country‟s road assets form a crucial backbone to any economy by seamlessly linking up people and goods to their respective markets, which in turn impro...

Maintenance has become a management issue, with its function as a contributor towards profit. This indicates the need for the maintenance operation to align with the business objectives and increase value for the enterprise. As a contributor to current management techniques, lean thinking approaches are now more commonly used. Without strong evidence to support the presence of generic lean thin...

this article, after explaining the concept of peace building in the framework of united nations peace operations, considers the challenges facing it. peace operations are a complex and inter-related set of activities which lack clear legal status in the united nations charter, but are accessible instruments for the maintenance of international peace and security. despite the fact that peace bui...
