چکیده
ln this paper we describe a desi&D methodoiO&Y for the development of (potentially multi· proceasor) re&l-time syatem. Our propoaed methodolo&y differa fundament&lly from current methodolo&y and serves to help mana&e the complexity of masaive-intensive systems. One of tht distin&uishin& aspects of this methodolo&y is in its ability to express timiog coostraints and verify to what extent sucb constraints are met. A aecond distinguishing upeet of this methodology is to develop a system aceordins to fivt viewa of systems. ln particular, the problema coneerned witb the transformation of the specifications into the parallel prosrams are addresaed. The propoaed methodolosy is applied to develop ao ooboard geoerator for generatiog transfer frames , complyaont to the CCSDS R.ecommeodations (34), (35). This onboard &entrator is implemented on a traosputer network (I), (2) . lndtz Ten111 Real-time systems, specification, performance evaluation , parallel processin,;, (:(.~<;OS . transputer.

Method integration: An approach to develop agent oriented methodologies
Agent oriented software engineering (AOSE) is an emerging field in computer science and proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. Despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. According to the defects resulted from weaknesses ...
متن کاملDemand-oriented timetable design for urban rail transit under stochastic demand
In the context of public transportation system, improving the service quality and robustness through minimizing the average passengers waiting time is a real challenge. This study provides robust stochastic programming models for train timetabling problem in urban rail transit systems. The objective is minimization of the weighted summation of the expected cost of passenger waiting time, its va...
متن کاملA cost-oriented model for multi-manned assembly line balancing problem
In many real world assembly line systems which the work-piece is of large size more than one worker work on the same work-piece in each station. This type of assembly line is called multi-manned assembly line (MAL). In the classical multi-manned assembly line balancing problem (MALBP) the objective is to minimize the manpower needed to manufacture one product unit. Apart from the manpower, othe...
متن کاملEvaluating the Efficiency of Firms with Negative Data in Multi-Period Systems: An Application to Bank Data
Data Envelopment Analysis (DEA) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. In conventional DEA models, the efficiency scores of Decision Making Units (DMUs) with non-negative inputs and outputs are evaluated in a special period of time. However, in the real world there are situations wherein performance of firms must be evaluated in multip...
متن کاملTowards Multi Dimensional Methods
Recently, new paradigms have emerged to improved standard object-oriented methods. However, most of these lack guidelines for developers on how to design complex real-life systems using these techniques. In this position paper, we investigate proposed methods and reason why they still fail to meet key requirements of the standard design methodology. We also present a few key requirements for su...
