Scheduling problems play a big role in manufacturing and planning the production for increasing the production efficiency and assigning the resources to operations. Furthermore, in many manufacturing systems there is a physical space between stages that called intermediate buffers. In this study, a model is proposed for minimizing the makespan of a hybrid flow shop scheduling problem with inter...

Short term prediction of traffic flow is one of the most essential elements of all proactive traffic control systems. Although various methodologies have been applied to forecast traffic parameters, several researchers have showed that compared with the individual methods, hybrid methods provide more accurate results . These results made the hybrid tools and approaches a more common method for ...

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

In this paper, the electrical consumption of a Research Center Building is derived of the bills, Then with defining of fuzzy Bus Thermal Coefficient objective function for heating, the amount of available heat selling to Research Center Building consumer that is produced by Biomass Solar Hybrid Source is calculated. With the capacity determination of Biomass Solar Hybrid Source to provide Therm...

We investigate the connections between the process algebra for hybrid systems of Bergstra and Middelburg and the formalism of hybrid automata of Henzinger et al. We give interpretations of hybrid automata in the process algebra for hybrid systems and compare them with the standard interpretation of hybrid automata as timed transition systems. We also relate the synchronized product operator on ...

In a standalone hybrid wind-diesel-battery system, the battery lifetime is often optimistically overpredicted by hybrid system designers and battery manufacturers. As a result, battery replacement takes place more often than required. One of the reasons is due to the underestimation of battery wear from the short charge-discharge cycles, otherwise known as microcycles. A microcycle takes place ...

Hybrid systems with memory refer to dynamical systems exhibiting both hybrid and delay phenomena. While systems of this type are frequently encountered in many physical and engineering systems, particularly in control applications, various issues centered around the robustness of hybrid delay systems have not been adequately dealt with. In this paper, we establish some basic results on a framew...

Pfaffian Hybrid Systems. Pfaffian hybrid systems, which we recently introduced in [18], are a sub-class of o-minimal hybrid systems which capture rich continuous dynamics and yet can be studied using finite bisimulations. In particular Pfaffian hybrid systems include hybrid systems with continuous dynamics definable by functions such as exp, sin, cos, and other trigonometric functions in approp...

We define controllability for hybrid systems as the existence of correct control-laws that transfer the hybrid plant between pre-defined subsets of the hybrid state-space. A methodology for analyzing controllability and synthesizing control-laws for a class of hybrid systems, applicable expecially in batch control, is proposed. We use a framework consisting of a hybrid plant and a hybrid contro...
