An approach to formulating and solving the problem of comprehensively evaluating the dynamic system performance is proposed. A MicroGrid represented in a multi-agent system (MAS) form is taken as an example. A unified definition of agents applied to the class of dynamic systems formalized in the form of continuous, discrete and discrete-event models is introduced. The performance efficiency of both the MicroGrid and its individual components (agents) is assessed. The developed flowchart for MicroGrid performance assessment serves as a basis for optimizing the MicroGrid performance indicators in the online mode. By using the proposed solution, it becomes possible to formalize the integration of heterogeneous objective functions into unified criteria by certain types and also taking into account the performance assessments of individual components in the interconnected system. Technical, economic and environmental criteria are considered as standard performance criteria. To obtain a generalized solution with taking into account the heterogeneity of the considered efficiency criteria, a fuzzy model based on the fuzzy sets theory is proposed as a tool for convolution of these criteria. The flowchart of the algorithm for MicroGrid performance assessment is developed taking as an example the design of a hybrid-generating and environmentally safe power supply system for the Arctic enclave with a specified configuration.

Production Dynamic

In the last ten years, the performance of Indonesia’s tea agroindustry has been decreased. It is shown by the decreasing of tea estate area as much as 2.18 percent per year, tea production decreased as much as 0.8 percent, and export volume decreased as much as 1,07 percent per year. This study were aimed to identify performance measurement results of tea production at Bantaran plantation area PT Perkebunan Nusantara XII based on the achievement of RKAP and evaluated the performance achieved through the production of tea agroindustry by dynamic system method. This method allowed to conduct comprehensive studies to study the behavior and improved system performance. This study was started from the observation, interviews, and document collection, which then was made causal loop diagram to the simulation model creation and validation of the model made. From the simulation, it came with conclusion, if there was no policy change, then Bantaran plantation area had a decreased performance status.

A good understanding of system dynamics is imperative to the design of any control strategy. Results of inaccurate models can lead to inefficient controls. However, the formulation of an accurate dynamic model requires high computational power and hence various simplifying assumptions are made while deriving the system equations. In order to illustrate this concept, a simple dynamic experiment of a double-pendulum is formulated and the responses obtained from the derived model and the actual model were compared. Inaccuracies of the derived model clearly showed up in the comparison. By taking into account factors, which were initially omitted for simplifying calculation, the inaccuracies observed could be minimized.

System Performance Evaluation

We discuss dynamic system performance evaluation in the river port utilizing queuing models with batch arrivals. The general models of the system are developed. This system is modelled byMX/M/n/mqueue with finite waiting areas and identical and independent cargo-handling capacities. The models are considered with whole and part batch acceptance (or whole and part batch rejections) and the interarrival and service times are exponentially distributed. Results related to the batch blocking probability and the blocking probability of an arbitrary vessel in nonstationary and stationary states have been obtained. Numerical results and computational experiments are reported to evaluate the efficiency of the models for the real system.
