In the contemporary global market, managing the entire supply chain has become crucial for competitive advantage in different industries. However, the realization and success of supply chain management (SCM) depends significantly on the previous supply chain modeling and simulation for analyzing complex systems. This study develops a modular approach for system analysis and design of supply cha...

An integrated visual modeling and simulation tool called Component-based System Modeling and Simulation (CoSMoS) is extended to support behavioral specification of parallel atomic DEVS model. An approach based on Statecharts and Graphical Modeling Framework has been developed and implemented for specifying behaviors of atomic models. One or more Statecharts can be developed for any atomic model...

Architectural modeling is an integral part of modern software development. In particular, diverse systems benefit from precise architectural models since similar components can often be reused between different system variants. However, during all phases of diverse system development, system variability has to be considered and modeled by appropriate means. Delta modeling is a language-independ...

In this paper we investigate some properties of congruences on ternary semigroups. We also define the notion of congruence on a ternary semigroup generated by a relation and we determine the method of obtaining a congruence on a ternary semigroup T from a relation R on T. Furthermore we study the lattice of congruences on a ternary semigroup and we show that this lattice is not generally modular...
