We investigate the late phases of the embedded systems’ life cycles, in particular the treatment of change requests, the integration of legacy components, and the problem of emerging platforms. We propose to tackle these issues in a model-driven design paradigm, on the behavioral models, and to employ techniques from automata theory, model checking and automata learning. The main practical impa...

Let π be a nonidling fully collaborative policy. Under any fully collaborative policy, our model is equivalent to one where the service requirements of successive customers at station j ∈ {1, . . . , N} are independent and identically distributed (i.i.d.) with mean 1 αjγj , service rates of collaborating servers are additive, and the service rates depend only on servers, i.e., μij = μi for all ...

Individual agile methods have never been practiced as defined, in the same way that Royce's waterfall [1] model never reflected actual practice. Instead, practitioners adapted the core principles of these processes in order to suit their needs. Understanding this is key to appreciating the agile mindset. What does exist is a set of principles1 which, when followed loosely, form the agile practi...

In Test-Driven development, first test is made according to the customer requirement and then code is prepared to execute this test successfully. In this approach, design is not done exclusively before preparing test cases and coding. Design emerges as software evolves but this may result in lack of design quality. We adapted TDD by incorporating exclusive architectural design phase in the succ...

This application note presents guidelines for measuring whether a design is compliant with AT&T 62411 jitter tolerance, jitter generation and jitter attenuation requirements. 62411 compliance is a necessary requirement for CPE (Customer Premises Equipment) which is connected to T1 lines provided by AT&T. These T1 lines may be either private-line or centraloffice access lines. 62411 may not appl...

In an increasingly dynamic world where both needs and technologies are changing rapidly, there is a requirement for whole-life Customer-oriented Processes (CoPs) for software systems and software development. In the pursuit of delivering 'fit for purpose' systems, the design of a CoP requires an holistic approach to understanding, engineering, managing and evolving the system and software needs...

This paper describes an operator workflow oriented information framework for services and network management. Particular attention is drawn on the requirement for a high-level management information specification. It proposes for this purpose a management information transformation formalism as a tool to specify the polymorph behavior of the information during its lifecycle across the operator ...

Practical implications – Complexity can be decreased if managers ensure less dependency between the satisfaction of customer requirements and position of the decoupling point. It is also advantageous to reduce the coupling level between fast delivery requirement in mass customization and the decoupling point placement. Furthermore, an effective variety management calls for the implementation of...

with the aim of reducing cost of electricity consumption and peak load reduction, tools requirement for better managing electricity consumption have become inevitable in recent years. smart home has some equipment which are controllable and this ability is used for increasing comfort and minimizing electricity cost for residence. as a key component of smart home , electric vehicle(ev) ,increase...

After a thorough investigation of end user requirement differences from a Database and a Data Warehouse, a strong case is made for specific Data Warehouse Management Systems (DWMS), in contrast to the trend of utilizing DBMS for Data Warehouse construction. The three type (Temporal, Nested Relational, Multidimensional) DWMS hypothesis, an original concept of Yoshioki Ishii, President, Software ...
